Water-based polybutadiene coating crosslinking agent
Polybutadiene coating materials. The hydroxy liquid polybutadiene resin (HTPB), maleic anhydride (anhydride), linseed oil, linotype oil, naphthenic acid cobalt, and rare earth drier.
Water-based polybutadiene coating process. In the reactor, to join 100 HTPB, 20 copies of maleic anhydride, a small amount of inhibitor, temperature to 100 ℃ 6 h. Add too much water, in the 90 ℃ 3 h reaction, reacts to heat up to 100 ℃ for 2 h. Cool down and remove excess water.
Join 18 linolenic acid glycidyl ester, 120 ℃ 5 h reaction, cooling, adding cosolvent, drier, neutralizing agent and water, stir for a quick water-based paint. Use iron sheets to soak and dry at room temperature.
Anion polybutadiene electrophoresis coating
Liquid polybutadiene. Electrodeposition coatings with polybutadiene is commonly relative molecular mass of 500 ~ 5000 liquid polybutadiene (LPB), the common preparation for under nitrogen atmosphere in the 30 l reaction kettle with 1 mol 芐 sodium base, 15 mol, toluene and 15 l n-hexane, then heat up to 30 ℃, add 10 l butadiene more than 2 h.
And then you add the methanol and you stop the polymerization. Add gypsum powder, stir well, filter the mixture and remove the base polymer transparent solution. The non-reactive butadiene, toluene and n-hexane were vaporized from the polymer solution, and the polybutadiene was obtained.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.

Anion. The anode electrophoresis coating is made by anionic polybutadiene, which is usually caused by anhydride reaction. The process for adding 1000 g in 2 l autoclave polybutadiene, maleic anhydride, 212 g to 300 g and 2 g xylene antigen 3 c, in nitrogen atmosphere reaction under 19 ℃ 8 h, under the low pressure steam out not reaction of maleic anhydride and xylene, get polybutadiene maleic anhydride. The polybutadiene is obtained by hydrolysis of the polybutadiene after the polybutadiene acid anhydride.
According to the formula ratio of polybutadiene, antioxidants, maleic anhydride, join the reaction kettle, xylene, nitrogen, after waiting for maleic anhydride melting, stirring, heating up to 200 + 10 ℃, insulation 4 h, 1 h to vacuum, after xylene extraction, resin viscosity and the acid value sampling test, qualified after the temperature to 140 ℃, add formula, amount of crosslinking agent, ethylene glycol butyl ether, butyl acetate, after 140 ℃ heat preservation 3 h, cool to filter out under 100 ℃.
Water-soluble polybutadiene resin after organic amine neutralization, join the pigments, fillers and additives, grinding fineness to qualified after a quick solid content is (50 + 2) % of the anodic electrophoretic coating H11-94.
Electrophoresis coating and film performance index. The black electrophoresis paint should be mixed with a solid content of 14 to 17 percent of the liquid, which can be applied after 24h. The pH of the tank is 8.0 ~ 9.0. Construction temperature is 25 ~ 40 ℃; The construction voltage is 100 ~ 180V; The conductivity is (1200 plus or minus 500) mu S. The penetration is greater than 16%.
The anode electrophoresis coating construction is convenient, the size groove is applicable. It is mainly used in automobile, agricultural machine, motorcycle, bicycle and mechanical and electrical products as anti-rust primer, and also can be used in the combination of steam matching and modu-product.
Polybutadiene is a polymer of 1, 3-butadiene. The abbreviation is PB. Used as catalyst, polymerization method and polymerization conditions of different and produce a variety of different structures of polybutadiene, such as cis - 1, 4 - polybutadiene (see image), anti - 1, 4 - polybutadiene, 1, 2 - polybutadiene, and cis 1, 4, anti - 1, 4 polybutadiene and 1, 2, 3 person mixed structure. Cis 1, 4 polybutadiene (hereinafter referred to as butadiene rubber, English abbreviation for CBR) and mixed structure of polybutadiene is synthetic rubber, called butadiene rubber BR, and 1, 2 - polybutadiene mainly used as adhesives and sealants.
