Paint crosslinking agent in acetal adhesive
2017-5-17 23:47:41
Paint crosslinking agent in acetal adhesive,It is one or more of the polyfunctional epoxy compound or epoxy resin, polyamide, polyamine, polyols, polyisocyanate vinegar.
The coating crosslinking agent in the non-aldehyde adhesive is described as follows:
1) polyfunctional epoxy compound can choose two glycidyl terephthalic acid and cool, phthalate glycidyl phthalate glycidyl between vinegar, vinegar, adipic acid two glycidyl vinegar, on the base benzoic acid two glycidyl ether vinegar and resorcinol diglycidyl ether, ethyl 2 drunk 2 glycidyl ether, three by methyl propane glycidyl ether, 1, 4 yiding glycol diglycidyl ether, propyl three drunk three glycidyl ether; Epoxy resin can be used in bisphenol A epoxy.
(2) multivariate by acid can choose terephthalic acid, phthalic acid, isophthalic acid, maleic acid, fumaric acid, citric acid, tartaric acid and malonic acid, succinic acid, adipic acid, even the benzyl formate, trimellitic formic acid, all three formate benzene;
(3) multiple amine can choose ethylenediamine, propylene amide, butyl diamine, hexamethylenediamine, divinyl three amine, triethylene tetramine, four ethylene amines, the b tomb ethylenediamine, para-phenylene diamine, o-phenylendiamine, m-phenylene diamine;
(4) polyols can choose ethylene glycol, propylene glycol, succinic drunk, self diol, neopentyl glycol, glycerin, three by methyl propane, pentaerythritol, glucose, fructose, diethylene glycol, ethylene glycol, hydroquinone, catechol, resorcinol;
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
More than 5 different peja vinegar can choose 2, 4 toluene 2 different atmosphere vinegar, 2, 6 a toluene two isocyanate vinegar, 4, 4 'freed one diphenyl methane two isocyanate, 2, 4' one diphenyl methane two isocyanate and cool, 2, 2 'one diphenyl methane two isocyanate vinegar, benzene two methylene two different atmosphere vinegar, 1, 5 a CAI diisocyanate.
Trimethylamine hydrochloride with 98% epoxy propane in 45 ~ 50 ℃ 4 h reaction, adding sodium hydroxide to 30 ~ 60 min reaction, adjust pH 7, in 0 ~ 5 ℃ to 3 get together cyanogen chloride reaction, then add the para ester reaction 4 h, crosslinking agent FKJ. Process: in 500 ml of three round bottom flask neck add 4.775 g trimethylamine hydrochloride, dissolved l5mL water, and stir constantly, heating up to 45 ~ 50 "C % drip with concentration of 98% epoxy chloropropane 5 ml, keep drops in half an hour out, drop after thermal reaction 4 h, get the product 1.
Keep stirring at room temperature with a 40 per cent concentration of NaOH aqueous solution in the product 1, and then continue to react 30 to 60min after completion. Filter the NaCl, which is produced by the reaction, and the pH is about 9, and the pH of the solution is about 7, and the pH is about 7, and you get the product 2.
Stirring at room temperature under the condition of product in 2 drops in the add too much concentrated ammonia, and after that, continue to 3 ~ 4 h reaction, the pH measurement 11 ~ 12, and then heated to 80 ℃ and the reaction liquid vacuum removing excess ammonia, deamination after pH measurement for 8 ~ 9. Cooled to 0 ~ 5 ℃, stirring constantly slowly drops under the solubilization of melamine in acetone solution to the above reaction solution with sodium carbonate to adjust control reaction pH value is about 6, until the pH change no longer receive product 3.
Product 3 reaction liquid heating up to a certain temperature, successively add a certain amount of counterpoint under stirring constantly ester and performance regulator X - NH - R, add again after thermal reaction about 4 h. At the end of the reaction, the salting, filtration, vacuum drying, the crosslinking agent FKJ.
