The deterioration of the durability of the concrete structure with hydrophobic treatment
leads to a significant decrease in the reliability and safety of the structure, which greatly endangers the normal use of the structure. There are many factors that cause the deterioration of the durability of the concrete, among which the corrosion of steel bars is one of the main reasons for the decrease in the durability of the concrete structure. one. Due to the corrosion of steel bars, a large number of concrete structures had to be repaired or demolished in advance, causing huge economic losses. Silane surface hydrophobic treatment can reduce the probability and rate of steel bar corrosion caused by external chloride ion erosion of concrete, delay the time for steel bar to start to corrode, and reduce the mass loss rate of corroded steel bars.
Textile auxiliary
silicone has a unique silicon-oxygen bond structure Si-O-Si, which endows larger bond angles and bond lengths, and small intermolecular forces. It is not easy to crystallize like ordinary organic molecules, so it has good air permeability; The high bond energy makes silicone polymers have outstanding heat resistance and excellent flexibility; the helical structure of the molecular chain and the methyl groups extend outward, making it have extremely low surface tension and good water repellency ;Silicon-hydrogen bond (Si-H) has greater activity, and can be hydrolyzed, condensed and cross-linked to form a film under the action of high temperature and metal salt; Due to the special structure, it has become an environmentally friendly textile printing and dyeing auxiliary with excellent performance, non-toxicity and no irritating odor.
Plastics, Rubber
In the plastics and rubber industry, the unique properties of silanes are used to enhance performance and improve process performance. Silane acts as a coupling agent and dispersant for fillers in the formulation of rubber and plastics, as a polymerization modifier in the synthesis of polypropylene to improve isotacticity, and as a crosslinker in the synthesis of polyethylene homopolymers and copolymers agent to increase the cross-linking point.1. Rubber compounding: Due to the benefits of using inorganic fillers instead of carbon black in reinforced rubber, silane has been widely used in the organic rubber industry. Compared with the use of carbon black, silica and other materials used for reinforcement Inorganic fillers in rubber can make rubber obtain unique and more beneficial physical and mechanical properties. 2. Plastic formula: used for polyethylene crosslinking to make wire sheath material: In an extruder containing peroxide heated to an appropriate temperature, silane-modified polyethylene containing trialkoxysilyl side chains is produced .


In the process of casting
and casting, natural and synthetic resins are used as binders for molds and core sands. However, due to the great differences in the structure and properties between sand and resins, it is not easy to produce chemical bonds between them, and they cannot penetrate and dissolve each other. It depends on the mutual attraction between molecules on the interface. Therefore, it is not enough to simply increase the area and quantity. Coupling agents are usually used in casting materials to enhance the bonding effect, that is, to enhance the bonding force between the resin mold-sand grain interface. . Adding a silane coupling agent can not only improve the strength of the resin sand, but also organically combine the resin and the sand through a chemical reaction to reduce the cost. As an occasion where the strength requirement is not very high, some high boilers of aminosilanes have also been widely used in consideration of cost reduction.
Paint, ink
With the unique ability of silanes to form covalent bonds between inorganic and organic components and the inherent stability of the silicon-oxygen bond, silanes endow these materials with resistance to physical, chemical, environmental and thermal degradation.
Silane monomers are widely used in coatings in the form of organofunctional alkoxysilanes, acting as adhesion promoters, pigment treatments and crosslinkers. Inorganic alkyl functional groups combine with various organic functional groups to form covalent bonds between organic polymers and inorganic surfaces such as dyes, fillers, glass and metallic materials. The functional groups and hydrolyzable alkoxy functional groups must be compatible with the chemistry of the organic polymer in the coating or ink.
Glass fiber reinforced material
Glass is extremely hydrophilic and can absorb water to the interface, resulting in weakening of the bonding force between glass fiber and resin. Silane coupling agent is one of the key components of glass fiber reinforced polymers. It can improve the bonding performance of glass fiber and resin, and greatly improve the strength, electrical, water resistance, and weather resistance of glass fiber reinforced composite materials. At present, it is quite common to use silane coupling agent in glass fiber The silane coupling agent used in this aspect accounts for more than 60% of its total consumption. According to the different chemical structures of the film-forming resins, the types of coupling agents commonly used in glass fibers are epoxy silane, methacrylic Silanes with reactive functional groups such as acyloxy groups.
In order to improve certain properties of organic adhesives (such as dry/wet adhesion, mechanical properties, storage stability, heat resistance, moisture resistance, weather resistance, etc.), or to reduce the cost of organic adhesives, often in adhesives Add some inorganic fillers. If the filler is pre-treated with a silane coupling agent, the polar groups on the surface of the filler react chemically with the silane coupling agent, which can greatly reduce the structural interaction between the filler and the resin, and not only make the filler less sensitive to the adhesive matrix resin. The compatibility and dispersibility are greatly improved, and the viscosity of the system is significantly reduced, so the amount of filler can be increased. For fillers with a large amount of hydroxyl groups on the surface such as glass and silica, it is completely ineffective for fillers without hydroxyl groups on the surface such as calcium carbonate and graphite.
Filler modification 
Fillers have gradually become important organic polymer additives and modifiers, which play an important role in reducing production costs and improving product performance. The hydroxyl groups on the surface of fillers are usually hydrophilic and exhibit incompatibility with organic polymers. For example, alkoxysilane is suitable for treating the surface of minerals, the hydroxyl groups on the mineral surface and the hydroxyl groups produced by the hydrolysis of silane are condensed, and the organic ends on the silane face outward, so that the minerals are better dispersed in the polymer Come, it is not easy to agglomerate, it can improve the coupling of resin and filler, and even make the filler into a reinforcing additive. Silanization treatment can improve the processing performance, mechanical properties and durability of the product in the following ways.
