Development of epoxy coating crosslinking agent
The development of epoxy coating crosslinking agent has been developed rapidly, and many new high performance crosslinking agents have emerged.
Epon HPT crosslinking agent 1061 and 1062, and by excluding ether bond in the molecular structure, containing hydroxyl, more can improve the water resistance, heat resistance, crosslinking agent and crosslinking of bisphenol A type epoxy resin with Tg content of up to 207 ℃, 1.4% ~ 1.6% water imbibition.
PN 1 31 and PN 1 40 are latent sexual couplets; Stable below 90 ℃, 90 ℃ can be crosslinked, prepared with the storage life of one-component epoxy adhesives is greater than 9 months.
Phenol, formaldehyde and melamine synthesis of phenolic resin (ATN), used as crosslinking agent for epoxy resin, have good flame retardancy, and can reach UL94 V - O grade. In whorls diamine (ATU) with different epoxide and acrylonitrile reaction, of adduct is liquid at room temperature, used as a crosslinking agent for long period of epoxy resin, not strict measurement, easy to use, almost non-toxic.
Crosslinking material tenacity, small shrinkage rate, high bonding strength, the tensile strength of 65 ~ 80 mpa, the impact strength of 14 ~ 16 kj / ㎡. To tetrabromobisphenol A dual (2 hydroxy ethyl ether and p-nitrophenyl formyl chloride reaction of aryl ether ester aromatic amine, used as A crosslinking agent of epoxy resin, crosslinking material has high strength, high toughness, high heat resistance, low water absorbability, the tensile strength of 95 mpa, the elongation at break > 12%, water < 1.3%.
Epoxy crosslinking agent development, worked out the hydrogenation of methyl dick anhydride (H - MNA), crosslinked bisphenol A epoxy resin is 162 ℃, thermal aging time is 1.5 times that of MNA and MeTHPA at 200 ℃ after 30 d bending strength was almost unchanged. In order to meet the moisture resistance of electronic packaging materials, a variety of heat-resistant crosslinking agents have been developed, mainly including the structure of phenolic resin.
HardeneHY940 sexual intercourse for modified low molecular polyamide latent agent, mixed with liquid epoxy resin, have six months to storage life at room temperature, 100 ℃ under present high reactivity, with excellent adhesion and mechanical properties.
T - 99 super flexible multi-functional epoxy crosslinking agent, colorless, transparent, non-toxic environmental protection, can be at room temperature or heating cross-linked epoxy resin, the crosslinking content more than 200% elongation at break, dominant, cracking has been confusing for the first time amine crosslinker crosslinked the brittleness of epoxy resin, greatly broaden the application field of epoxy resin adhesives.
