According to the chemical structure and composition of the coupling agent, it is divided into four categories: organic chromium complexes, silanes, titanates and aluminates:Folded chromium complex couplingAgent Chromium complex coupling agent was developed in the early 1950s. The metal chromium complex formed by unsaturated organic acid and trivalent chromium ion has mature synthesis and application technology and low cost, but the variety is relatively single.Folding titanate coupling agentAcco ...
Coupling agent is also called surface modifier. It can reduce the viscosity of the synthetic resin melt in the plastic processing process, improve the dispersion of the filler to improve the processing performance, and then make the product obtain good surface quality and mechanical, thermal and electrical properties.1. Classification of coupling agentAccording to the chemical structure and composition of the coupling agent, it is divided into four categories: organic chromium complexes, silanes ...
Silicone resin is a collective term for a type of polymer in which silicon atoms and oxygen atoms are alternately connected to form a skeleton, and different organic groups are connected to silicon atoms. The structure of silicone resin contains both "organic group" and "inorganic structure". This special composition and molecular structure make it a combination of organic and inorganic functions. The following editor introduces the properties of silicone resins and the uses ...
Quaternary ammonium salts used as softeners, according to theirIn terms of learning structure, there are mainly the following:Among the above four quaternary ammonium softeners, except for the first type of alkyl trimethyl quaternary ammonium salt, which tends to be eliminated, the other three are full of vitality. Their applications on textiles are divided into three types, namely; washing softener, household softening conditioner and fabric softener. The softening effect of dialkyl dimethyl qu ...
Silicone rubber has a variety of excellent properties, but its mechanical properties such as compressive strength and tearing strength are poor, and cannot meet the requirements of the process. Fillers need to be added to modify and strengthen it. When MQ silicone resin is used as a reinforcing filler, it can not only increase the strength of the rubber matrix, but also will not increase the viscosity of the system too fast to facilitate subsequent operations, and the prepared vulcanizate has be ...
Softener requirements1. Under various soft processing conditions, the working fluid should be very stable. 2. Does not reduce the whiteness and color fastness of fibers or fabrics.3. The softened fiber or fabric is not easy to be discolored by heat, and there should be no changes in color, feel, or odor during storage.4. If the softener is emulsion, its emulsion stability is better.5. According to different processing requirements, it can have proper water absorption or water repellency, an ...
Organic silicone adhesive is a one-component, semi-transparent paste-like room temperature curing adhesive, which is a high-performance elastomer that is naturally cured. It has excellent resistance to cold and heat, aging resistance and electrical insulation, and has good adhesion to most metal and non-metal materials.Organic silicone adhesive is a one-component, semi-transparent paste-like room temperature curing adhesive, which is a high-performance elastomer that is naturally cured. It has e ...
A substance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, the water can spread on the surface of the solid material or penetrate the surface, thereby wetting the solid material.Wetting agent is a surface active agent that can make solid materials more easily wetted by water by reducing its surface energy.Such as sulfonated oils, soaps, pull open powder BX, etc., soy lecithin, mercaptans, hydrazides and mercaptan acetals, etc. c ...
Modified resin adhesive refers to a type of adhesive made by adding thermoplastic resin or synthetic rubber as a base material to thermosetting resin. Also known as composite adhesives and hybrid adhesives. Refers to various hybrid polymer adhesives.Modified resin adhesive refers to a type of adhesive made by adding thermoplastic resin or synthetic rubber as a base material to thermosetting resin.

Wetting agent is a special surfactant that can reduce the internal surface tension between solid or liquid. Applying wetting agents to lawns can increase the ability of water to wet water on hydrophobic soils or other growing media. The surface tension of water is the ability of surface water to cohere to the center of the body of water. The water droplet containing wetting agent spreads its attachment area on the hydrophobic surface, which is larger than the ordinary water droplet attachment ar ...
