The application of silane coupling agent

Silane coupling agent is essentially a class of organic functional groups of silane, in its elements at the same time be able to have the quality and inorganic materials (such as glass, silica sand, metal, etc.) combined with the chemical reaction of groups and the organic matter and materials (synthetic resin Etc.) combined with the chemical reaction group.
The application of silane coupling agent can be broadly divided into three areas:
(A) for the surface treatment of glass fiber, glass fiber can improve the adhesion properties of resin and has greatly enhanced the glass fiber-reinforced composites strength, electrical, water resistance, anti-climate, such as performance, even in the wet, it the mechanical properties of composite materials to improve the results would be very significant. At present, the use of glass fiber silane coupling agent has been quite common for this area of silane coupling agent about the 50% of total consumption, which is used in more varieties is a Vinyltrimethoxysilane,Amino Silane, propylene-methyl silane and so on.
(B) inorganic filler used to fill plastic. Can be conducted in advance of the filler surface treatment, but also directly to join in the resin. Fill in the resin can improve the dispersion and adhesion, improving technology to enhance performance and fill plastic (including rubber), machinery, electrical and weather-resistant properties, and so on.
(C) used as a sealant, adhesive and paint the tackifier, to increase their bonding strength, water resistance, weather-resistant properties, and so on. Silane coupling agent is often able to resolve some of the adhesive material for a long time can not be solved. Silane coupling agent tackifier as the role of the principle that it is, there are two groups; a group and stick to the combination of frame materials; and the other is a group with the polymer material or adhesive , In order to form a strong bond interface chemical bonds higher, greatly improved the adhesive strength. The application of silane coupling agent in general there are three ways: First, as a reinforcing material surface treatment agent; second is added to the adhesive, three directly into the polymer material. From its full effectiveness and cost point of view, the first two methods better.
Silane coupling agent in the adhesives industry specific applications the following areas:
① structural adhesives in the metal and non-metallic bonding, the use of silane-type tackifier, and the metal oxide will be able to condensation, or with another silane alcohol condensation, so that the atoms of silicon and plastic materials were firmly on the surface Contact. If the phenolic structure of nitrile rubber silane for the addition of tackifier, can significantly improve the bonding strength.
② bonding in the glass fiber connection at home and abroad have been widely used for silane treatment agent. It can interface with the chemical reaction, so as to enhance the bonding strength. For example, if neoprene bonding agents do not have to deal with silane, peel strength for bonding 1.07 kg / cm 2, if used to make amino-silane agent, the bonding strength of the spin-off of 8.7 kg / cm 2.
③ in the rubber and other materials bonding, silane tackifier has a special function. It is clear to raise a variety of rubber and other materials of the bonding strength. For example, glass and polyurethane rubber bonding, if do not have to deal with silane agent, adhesive peel strength to 0.224 kg / cm 2, if the increase in silane, peel strength was 7.26 kg / cm 2.
④ have been unable to use ordinary adhesive bonding solution to the issue of silane coupling agent can be used at times to solve. Such as aluminum and polyethylene, silicone rubber and metal, silicone rubber and plexiglass can be based on chemical bond theory, the choice of silane coupling agent, to be a satisfactory solution. For example, the use of vinyl-tert-butyl peroxide silane (Y-4310) can bond with aluminum foil and polyethylene; butadiene with the three-silicone triethoxysilane can and pull away from the intensity of metal To reach 21.6 ~ 22.4 kg / cm 2. General adhesive resin or with the use of coupling agent can not only improve the adhesive strength, which is more important is to increase the adhesive force of the water resistance and durability. Such as polyurethane and epoxy resin materials, although many have high adhesive strength, adhesion, but the water resistance and durability is not ideal; adding silane coupling agent after this performance can be significantly improved .
Silane coupling agent of the other aspects of the application include:
① so that the immobilized enzyme attached to the glass substrate surface,
② oil well drilling in the sand,
③ so that the brick surface with a hydrophobic,
④ through the anti-moisture absorption, so that the fluorescent coating on the surface has a high resistance;
⑤ improve the column of liquid organic glass surface relative to the moisture absorption

New silane coupling agents for truck tire applications

There are many applications of silane coupling agents,today,Nanjing Aocheng Chemical CO., LTD  will tell you more about new silane coupling agents for truck tire applications are as follows:

The use of silica to reinforce elastomers is well known in the passenger car tire industry. The silica is chemically bonded to the rubber matrix using silane coupling agents. Sulfur-containing alkoxysilanes, such as 1-(trietboxy-silanyl)-3-[3-(triethoxy-silanyl)-propyltetrasulfanyl]-propane (5), often referred to as TESPT, and octanethioic acid S-[3-(triethoxy-silanyl)-propyl] ester (6), are used to covalently bond the rubber to the silica. The silanes (5) and (6) contain functional groups that react well with the rubbers typically used in passenger tire tread compound, such as styrene-butadiene rubber and butadiene rubber. Because these rubbers are chemically bonded or linked to the silica, the silica-filled elastomer is better able to transfer stress and has less hysteresis than carbon black-filled elastomers. In carbon black-filled elastomers, the rubber is physi-adsorbed onto the surface of the filler. These characteristics of the silica-filled elastomers reduce the rolling resistance and improve the wet traction of passenger car tires.

Reducing rolling resistance and extending wear life of tread compound are also of strong interest for truck tires. The tread compounds used in fabricating truck tires are based upon natural rubber. When silica replaces carbon black in natural rubber-based formulations, a reduction of rolling resistance is observed. However, these compounds have poor wear properties. Tread compounds containing silica filler and silanes (5) or (6) are unable to match the wear performance of tread compounds containing highly reinforcing carbon black fillers. The replacement of carbon black by silica in truck tread compounds has been stymied by ineffective coupling of the silica to natural rubber.

Silanes Protect Concrete Road Surfaces from Water Penetration

We know that there are many applications of silanes ,such as silane coupling agent,silane adhesion promoters,silane crosslinkers,silane moisture scavengers,so the effect of silane and we know what?We will tell you more about the effect of silane in water penetration are as follows:

Drivers may have fewer potholes to dodge, and local governments may be able to save money, thanks to Isobutyltrimethoxysilane for concrete formulators that can help repel water and protect highway infrastructure from weather damage.

Harsh weather wreaks havoc on roads and bridges, which can lead to dangerous driving conditions, In addition, increased maintenance costs can be a drain on severely strained state and local budgets. So it would be grateful to solve these problems by just adding something into the concrete.

The freeze-thaw cycles in winter allow water to penetrate the concrete road surfaces. When that water freezes, it expands, which creates pressure that causes the concrete to crack, resulting in hazardous potholes. On top of that, the seeping water often carries deicing salts with it, which can cause or accelerate corrosion of steel reinforcing bars, compromising the integrity of the infrastructure.

Isobutyltrimethoxysilane can offer water repellent properties to concrete when applied as a penetrating treatment. Silane molecules are small and reactive, and work at a microscopic level by penetrating into and bonding to the concrete. Once applied, the layer of silane, which even in high-strength concrete can be up to 4-5 millimeters thick, creates an umbrella of protection that keeps water out.

Using silanes as a penetrating treatment in concrete is one way to help keep roads safer and longer lasting, Isobutyltrimethoxysilane provides a convenient, proven and cost-effective way to get the right products to help prevent weather damage from occurring in the first place, so that local governments can spend less money repairing infrastructure.
