What are coupling agents and types?
May 11, 2021 What are coupling agents and types?
Coupling agent is a kind of material with two different functional groups. The most characteristic of its molecular structure is that the molecule contains two groups with different chemical properties. One is an inorganic group, which is easy to react with the inorganic surface; the other is an organic group, which can react with synthetic resin or other polymers or form hydrogen bonds and dissolve in it. Therefore, the silane coupling agent is called "molecular bridge", which can improve the interface interaction between inorganic and organic materials, so as to greatly improve the properties of composite materials, such as physical properties, electrical properties, thermal properties, optical properties and so on. Coupling agent used in rubber industry can improve the wear resistance and aging resistance of tire, rubber sheet, hose, rubber shoes and other products, and reduce the amount of NR, thus reducing the cost. The function of coupling agent in composite materials is that it can react with some groups on the surface of reinforced materials, and react with matrix resin, forming an interface layer between reinforcement materials and resin matrix, which can transfer stress, so as to enhance the bonding strength between reinforcement materials and resin, improve the properties of composite materials, and prevent other media from seeping into the interface It is beneficial to the aging resistance, stress resistance and electrical insulation properties of the products. A plastic additive used to improve the interfacial properties of synthetic resins with inorganic fillers or reinforcements. Also known as surface modifier. It can reduce the viscosity of synthetic resin melt and improve the dispersion of filler in the process of plastic processing, so as to improve the processing performance, and then make the products obtain good surface quality and mechanical, thermal and electrical properties. Its dosage is generally 0.5-2% of that of filler. Coupling agents are generally composed of two parts: one is an inorganic group, which can interact with inorganic fillers or reinforcing materials; the other is an organic group, which can interact with synthetic resin.
Introduction and application of silane coupling agent?
May 11, 2021 Introduction and application of silane coupling agent?
Silane coupling agent is developed by United carbide company of USA, which is mainly used for glass fiber reinforced plastics. The molecular structure formula of silane coupling agent is generally y-r-si (or) 3 (where y-organic functional group, sior silyloxy group). Silyloxy groups are reactive to inorganic compounds, and organic functional groups are reactive or compatible with organic compounds. Therefore, when the silane coupling agent is between the inorganic and the organic interface, the organic matrix silane coupling agent inorganic matrix bonding layer can be formed. The typical silane coupling agents are A151 (vinyl triethoxysilane), A171 (vinyl trimethoxysilane), A172 (vinyltriethoxysilane), etc. The use of silane coupling agents can be summarized into three aspects Appearance treatment It can improve the bonding function of glass fiber and resin, greatly improve the strength, electrical, water resistance, weather resistance and other functions of glass fiber reinforced composite materials. Even in wet state, it has a significant effect on the mechanical function of composite materials. Silane coupling agents have been widely used in glass fiber. The silane coupling agents used in this field account for about 50% of the total consumption. Among them, vinyl silane, aminosilane, methacryloyloxysilane and so on are widely used. Filled plastic The surface treatment of the filler can be carried out in advance, or it can be directly added into the resin. It can improve the dispersion and adhesion of fillers in the resin, improve the compatibility between inorganic fillers and resins, improve the process function and improve the mechanical, electrical and weather resistance functions of filled plastics (including rubber). Used as tackifier for sealants, adhesives and coatings It can improve their adhesive strength, water resistance, weather resistance and other functions. Silane coupling agents are often able to deal with the problem that some materials cannot be bonded for a long time. The effect principle of silane coupling agent as tackifier is that it has two groups; one group can combine with the skeleton data to be adhered; the other group can combine with polymer materials or adhesives, thus forming a strong chemical bond at the bonding interface, which greatly improves the bonding strength. There are three ways to use silane coupling agent: first, as a surface treatment agent for skeleton data; second, adding it to adhesive; third, directly adding it to polymer data. From the perspective of giving full play to its effectiveness and reducing costs, the first two methods are better.
Usage and dosage of coupling agent
May 11, 2021 Usage and dosage of coupling agent
1、 Usage 1. Pretreatment of pigments and fillers Although it is difficult to coat titanate silane coupling agent on the surface of pigments and fillers in advance, the treatment effect is better. Dissolve the coupling agent in a small amount of toluene, xylene and other benzene solvents, add human pigments and fillers, and properly heat up to about 100 ℃ under high-speed stirring (about 1000r / min), stir for about 0.5h, so that each pigment and fillers particles can be coated with a layer of coupling agent. After coating with coupling agent, the pigment and filler can be used to make coating. 2. Direct addition method In the process of paint making, coupling agent is directly added before high-speed laxity. Use solvent gasoline, xylene and other solvents to dissolve the weighed coupling agent, disperse it into the organic base material, participate in the high-speed dispersion of pigments and fillers, and then make the coating according to the usual method. The water-soluble coupling agent is used for the water-based coating, and the treatment method is as described above, with water as the solvent. 2、 Dosage Theoretically, the amount of coupling agent is to make all hydrophilic reaction groups in the coupling agent react with the hydroxyl or proton supplied by the pigments and fillers. There is no need to excess, but in fact, the most appropriate amount should be determined according to the particle size of the pigments and fillers and the situation of the surface functional groups. The relationship between viscosity and amount of coupling agent can be obtained by viscosity measurement. The most suitable amount of titanate is the biggest point of viscosity decrease. According to the experience, the amount of coupling agent should be 1% - 2% of the amount of solid pigments and fillers in the coating. The finer the particle size of pigments and fillers, the larger the surface deposit, and the more coupling agents are used. In conclusion, titanate coupling agents with different groups can be planned according to the needs of the coating industry, so that they can become specific or multifunctional auxiliaries,
