Paint crosslinking agent effect

Paint crosslinking agent effect:Crosslinking agents are mainly used in polymer materials (rubber and thermosetting resin). Because the molecular structure of the polymer materials as one long line, not crosslinked intensity at the low, easy to break, and there is no elastic, the effect of crosslinking agent is to produce chemical bonds between the molecules of the form, the linear molecules each other together, form a mesh structure, increase strength and flexibility of the rubber, rubber crosslinking agent is mainly used in the sulfur, in addition to promoter.

Various types of plastic (polyethylene, polyvinyl chloride, chlorinated polyethylene, EVA, polystyrene, etc.) interconnection and modification. The heat crosslinking is usually 1 to 3 percent, plus 2 isopropyl benzene (DCP) is 0.2-1%. Irradiated crosslinking adds 0.5 to 2%, no more DCP. The heat resistance, flame resistance, solvent, mechanical strength and electrical properties of the products can be improved significantly. It will improve the quality of the product significantly more than the single use of the oxide system. Typical for polyethylene, polyethylene/chlorinated polyethylene, polyethylene/EVA crosslinked cable and high polyethylene high, low foaming products.

2, ethylene propylene rubber, all kinds of fluorine rubber, CPE and other special rubber vulcanization (with DCP and use, general dosage is 0.5 to 4%), can significantly shorten curing time, improve the strength, abrasion resistance, solvent resistance and corrosion resistance.

The crosslinking of acrylic and styrene exchange resin. It is no less than divinyl benzene crosslinking agent dosage, high quality, to the preparation of fouling resistance, strength, large pore size, heat, acid and alkali resistance, oxidation resistance and other excellent properties of ion exchange resin. This is newly developed at home and abroad, promising new ion-exchange resin.

Polyacrylate, polyalkyl acrylate and other modifications. It can significantly improve the performance of heat resistance, optical performance and processing. Typical for the heat resistant modification of common organic glass.

Modification of tree ester of epoxy resin, DAP (polyphthalate). It can improve heat resistance, adhesion, mechanical strength and dimensional stability. It is typical for the modification of epoxy filling and packet sealing.

The crosslinking and modification of unsaturated polyester and thermoplastic polyester. It can significantly improve heat resistance, corrosion resistance, dimensional stability, weathering and mechanical properties. Typically used to improve the thermal heat resistant unsaturated polyester glass fiber reinforced plastic products, using the temperature of the modified products can reach above 180 ℃.

7, the homopolymer of TAIC itself - poly triene propyl different cyanuric acid ester as a transparent, hard, heat resistance, excellent electrical insulating resin, can be used to glue the glass and ceramic etc. Typically used to make multi-layer safety glass.

8, polystyrene, styrene and TAIC, which can be made transparent and broken products.

9, metal heat resistance, radiation resistance, weatherability of protectant, TAIC prepolymer on the metal surface plating, the baking coating has very good heat resistance, radiation resistance, weather resistance and electrical insulation. Typical used in the manufacturing of micro-electronic products such as printed circuit boards and other insulation materials.

It is used as an intermediates for light curing coating, photoresist, flame retardant and flame retardant crosslinking agent. Typical for the synthesis of high efficiency flame retardant TBC and flame retardant DABC.
