Coupling agent

In plastic mixing, to improve the synthetic resin and inorganic filler or reinforcement of the interface performance of a kind of plastic additives. Also known as surface modification agent. It can reduce in the process of plastic processing of synthetic resin melt viscosity, improving filler points divergence in order to improve the processing performance, thus make the products obtain a good surface quality and mechanical, heat and electric properties. Its dosage 0.5 for filling agent? 2%. Coupling agent generally consists of two parts: part is inorganic groups, can with the inorganic filler or reinforcement effect; The other part is organic affinity groups, but with synthetic resin.

Coupling agent is a kind of material that has two different functional groups, the biggest characteristic of its molecular structure is molecules contain property difference of the two groups, one is inorganic groups, easy to react with inorganic surface; The other is a hydrophilic organic groups, which can react with synthetic resin or other polymer or generate hydrogen bond the dissolved. So coupling agent is referred to as a "bridge", to improve the interfacial interaction between inorganic and organic compounds, thus big big improve the performance of composite materials, such as physical properties, electrical properties, thermal properties, optical properties, etc. Coupling agent used in rubber industry, can improve the tires, rubber sheet, rubber hose, rubber shoes and other products of abrasion resistance and aging resistance, and can reduce the dosage of NR, thereby reducing the cost. Coupling agent on the role of composite materials is that it can react with some groups on the surface of the reinforced material, and can react with matrix resin, between reinforcing materials and resin matrix in the formation of an interface layer, boundary layer can pass stress, so as to enhance the bonding strength between the reinforcing materials and resin, which improves the performance of composite materials, can also prevent other medium to permeate interface at the same time, improve the interface state, is advantageous to the products resistance to aging, stress and electric insulation performance.

The main function function

Glass fiber, glass fiber reinforced plastic: improving composite wet state physical and mechanical strength, wet state electrical properties, and improve the set of glass fiber bundle of sex, protective and processing technology.

Adhesives and coatings, high bonding strength, weather resistance, under wet state, improve the pigment dispersion, improve the wear resistance and crosslinked resin。

Casting: to improve the strength of the resin sand. In order to realize the high and low gas.

Rubber products to improve mechanical strength, wear resistance, wet electrical properties and rheology.

Sealant: to improve the wet bonding strength, improve the dispersion of filler and abrasion resistance。

Textile: make textile soft plump, improve its waterproof and adhesive force of dye。

Printing ink: improve the bonding strength of the invasive.

Filler surface treatment: improve the compatibility of filler and resin in the resin, invasive and dispersion.

Crosslinked polyethylene: used for crosslinking polyethylene cable and hot water pipe to enhance strength. Durability and service life.

Silane coupling agent: A172JN1204JN950 KH550KH560KHB92 aluminum acid ester
