2017-2-23 17:50:13
Crosslinking agent USES 1, a variety of thermoplastic (polyethylene, polyvinyl chloride (PVC), chlorinated polyethylene, EVA, polystyrene, etc.) of crosslinking and modification. Thermal crosslinking generally add quantity for 1-3%, plus dicumyl peroxide (DCP) of 0.2-1%; Irradiation crosslinking adding amount of 0.5 to 2%, can no longer add DCP. After crosslinking can significantly improve the heat resistance and flame retardant, solvent resistance, mechanical strength and electrical, etc. It than single crosslinked by peroxide system to significantly improve the quality of products, and no peculiar smell. Typically used in polyethylene, polyethylene (PE)/chlorinated polyethylene, polyethylene/EVA crosslinking polyethylene cable and high and low foaming products.
Crosslinking agent USES 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%), and can significantly shorten curing time, improve the strength, abrasion resistance, solvent resistance and corrosion resistance.
3 styrene, acrylic acid, crosslinking agent USES type ion exchange resin crosslinking. 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 a recently developed at home and abroad, prospect is very good new type of ion exchange resin.
Crosslinking agent USES 4, polyacrylate, modification of poly (alkyl acrylate etc. Can significantly improve the thermal stability, optical properties and process performance, etc. Typical for ordinary heat resistant modification of organic glass.
Crosslinking agent USES 5, epoxy resin, DAP (eps formate diallyl esters) modified resin. Can improve the heat resistance, adhesion, mechanical strength and dimensional stability. Typically used in epoxy potting compound and material modification.
Crosslinking agent USES 6, unsaturated polyester and polyester thermoplastic crosslinking and modification. Can significantly improve the heat resistance, chemical corrosion resistance, dimensional stability, weathering resistance and mechanical properties, etc. 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 ℃.
Crosslinking agent USES 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 in the manufacture of multilayer safety glass.
Crosslinking agent USES 8, polystyrene in plasticizing, styrene and TAIC, such as copolymerization modification, can be made transparent, ground resistance of products.
Crosslinking agent USES 9, protective metal heat resistance, radiation resistance, weatherability, TAIC prepolymer on the metal surface plating, the baking coating has very good heat resistance, radiation resistance, weather resistance and electrical insulation. Typical printed circuit board used in the manufacture of microelectronic products such as insulation.
Crosslinking agent USES 10, used for uv curing coating, photoresist, flame retardants and flame retardant of crosslinking agent and other intermediates. Typically used for synthesis of TBC and efficient fire retardants crosslinking agent DABC.
Halogen atoms of chlorine, fluorine, bromine can make polymer becomes sensitive, but there are exceptions, such as polyvinylidene fluoride (PVC, ETFE and so on.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Containing other than the main chain of carbon atoms of:
O main chain by ionization vulcanization of PDMS materials - n - (SiR2 - o -);
O by ionization vulcanization main chain of the polyamide - (R1 - NH - CO - R2 -) n;
O polymer is sensitive to radiation degradation of cellulose base;
O the main chain of polyacetal - (CH2 - o -) n - is sensitive to radiation degradation;
Aromatic hydrocarbon alicyclic amorphous polyamide less affected;
The tensile strength of the alloy in the elongation at break increased significantly at the same time, increased significantly, this may be a sign of a large number of crosslinking.
S. DADBIN etc (polymer degradation and stability, 89200, p. 436) through the dose of 5 million electron volts accelerators for 40 to 150 kGy electron beam irradiation crosslinking of polyamide 6 was studied.
Tensile strength and elongation at break of pure PA6 less affected.
Pure PA6 molecular weight affected less, until 100 kGy dose and then rise significantly.
Cooperate with crosslinking agent TAC composites slightly raised rush strength, and elongation at break is almost not decline. Thermal deformation temperature increased significantly.
