Silicone fluid is a polyorganosiloxane of different degree of polymerization chain structure. The most commonly used silicone fluid is  methyl silicone oil . Silicone fluids are generally colorless (or light yellow), odorless, non-toxic, non-volatile liquids.Silicone fluid is insoluble in water, methanol, glycol and -ethoxyethanol. It is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, which is slightly soluble in acetone, dioxane, ethanol and alcohol. It has a small vapor pressure, a high flash point and a flash point, and a low freezing point. As the number of segments n differs, the molecular weight increases and the viscosity increases, so that the silicone fluid can have various viscosities.  According to chemical structure, silicone fluid is divided into methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, me

Functional silanes , together with silicone rubber, silicone oil and silicone resin, are called four major categories of organic silicone materials. Structurally, small molecule silicones whose main chain is -Si-OC-structure are generally referred to as  functional silanes , while small molecule intermediates and polymer macromolecules whose main chain is -Si-O-Si-structure is called siloxane or polysiloxane, that is, silicone rubber, silicone oil, silicone resin and other silicone compounds.  Functionally,  functional silanes  are mostly hybrid structures. Most products contain both polar and non-polar functional groups in the same molecule. They can serve as interface bridges between inorganic and organic materials or directly participate in the crosslinking of organic polymeric materials. The combination of reactions, which greatly improve the material properties, is a very important and very versatile additive.  Functional silanes have the following different classification methods

Silane coupling agent was developed by United Carbide Corporation, which is mainly used for glass fiber reinforced plastics. The molecular structure of the silane coupling agent is generally: Y-R-Si(OR)3 (wherein Y-organofunctional group, SiOR-siloxy group). The siloxy group is reactive with inorganic substances, and the organic functional group is reactive or compatible with organic substances. Therefore, when the  silane coupling agent  is interposed between the inorganic and organic interfaces, a bonding layer of an organic matrix-silane coupling agent-inorganic matrix can be formed. Typical silane coupling agents are A-151 (vinyltriethoxysilane), A-171 (vinyltrimethoxysilane), A-172 (vinyltris(β-methoxyethoxy)silane), and so on. Introduction to Silane Coupling Agent Here, n = 0 ~ 3; X---hydrolyzable group; Y---organic functional group, which is capable of reacting with a resin. X is usually a chloro group, a methoxy group, an ethoxy group, a methoxyethoxy group, an acetoxy group

Surface pretreatment method The silane coupling agent is formulated into a dilute solution having a concentration of 0.5 to 1%. When used, it is only necessary to apply a thin layer on the cleaned surface to be adhered, and after drying, the glue can be applied. Most of the solvents used are water, alcohol (methanol for methoxysilane, ethanol for ethoxysilane), or a mixture of hydroalcohol, and water with no fluoride ion and inexpensive non-toxic ethanol or isopropanol. In addition to the aminoalkyl silane, solutions prepared from other silane coupling agents are required to be added with acetic acid as a hydrolysis catalyst and the pH is adjusted to 3.5 to 5.5. Long-chain alkyl groups and phenyl silanes are not suitable for use as aqueous solutions because of their poor stability. Chlorosilane and ethoxysilane are accompanied by a severe condensation reaction during hydrolysis, and should not be used as an aqueous solution or a hydroalcoholic solution, and used as an alcohol solutio

Pretreatment filler method The filler is placed in a solid mixer (high-speed solid mixer HENSHEL or a V-type solid mixer, etc.), and the above silane solution is directly sprayed on the filler and stirred. The higher the rotation speed, the better the dispersion effect. Generally, stir for 10-30 minutes (the slower the speed, the longer the time), and the filler should be dried at 120 °C (2 hours). Aqueous solution Aqueous solution (glass fiber surface treatment agent): The glass fiber surface treatment agent often contains: a film former, an antistatic agent, a surfactant, a coupling agent, and water. The amount of the coupling agent is generally from 0.3% to 2% of the total amount of the glass fiber surface treatment agent. First, the pH of the aqueous solution is first adjusted to a certain value with an organic acid or a salt. Under sufficient stirring, silane is added until it is transparent, and then the remaining components are added. For the poorly soluble silane, isopropanol c

Among the two types of silane coupling agent having different properties, the Y group is the most important, which directly determines the application effect of the  silane coupling agent . The bonding strength of the organic adhesive can be improved only when the Y group can react with the corresponding matrix resin. It is generally required that the Y group be compatible with the resin and can undergo a coupling reaction, so for different resins, a silane coupling agent containing an appropriate Y group must be selected. When Y is an unreactive alkyl or aryl group, it is ineffective for polar resins, but can be used for bonding of non-polar resins such as silicone rubber, polystyrene, and the like. When Y contains a reactive functional group, it should be paid attention to its reactivity and compatibility with the resin used. When Y contains an amino group, it is catalytic, which can be used as a catalyst in the polymerization of phenolic, urea-formaldehyde, melamine formaldehyde, an

There are generally three methods for the application of silane coupling agents: One is a surface treatment agent as a skeleton material; the other is added to the binder, and the third is directly added to the polymer material. The first two methods are better from the perspective of giving full play to their effectiveness and reducing costs. The application of silane coupling agents can be roughly summarized into three aspects: 1. It is used for the surface treatment of glass fiber, which 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. Even in the wet state, it has a significant effect on the mechanical properties of the composite. The use of  silane coupling agents  in glass fibers has become quite common. The silane coupling agent used in this aspect accounts for about 50% of the total amount consumed, among them, the more widely used va

The polyether modified silicone oil is a unique silicone nonionic surfactant which is obtained by graft copolymerization of polyether and dimethylsiloxane.  Introduction:  When making products,  polyether modified silicone oil  can obtain various silicone surfactants with different properties by modifying the number of silicone oil chains or changing the ratio of polyether Eo to Po and changing the number of chain links and terminal groups, to meet the needs of a variety of industries.  Use ofmodified silicone oil: 1. In the plastic greenhouse industry: it can be added as an internal additive to plastics to produce anti-fog and improve light transmittance in a non-drip film greenhouse.  2. Used in fabric finishing agent: it is soft, especially suitable for underwear, bed sheets, towels, etc. It is not only soft, but also absorbs sweat and is comfortable to wear.  3. The leveling agent used in paints and polyurethane pastes can reduce the internal friction and stress of the molecules, t
