preparation example Construction

[0027]The preparation process of the glue is as follows: firstly add trimethylolethane, ethyl diisocyanate cyclohexane, acetone, dicarboxymethyl propionic acid, and monoethanolamine into the reaction kettle in sequence, and continue for 28-42r / s Stir at a high speed for 3 to 5 minutes to obtain a slurry; then add alkylene ether, acetyl tributyl citrate, ammonium polyacrylate, methyl tin mercaptide, isopropyl titanate, and titanium dioxide to the slurry in the reactor in sequence , and continue to stir at a speed of 15-18r / s for 15-25 minutes, making the state of each component of the slurry more stable and relatively dispersed, improving the thermal stability of the slurry and reducing the impact of light; finally, the propane Add diamine, diethylthiotoluenediamine, and diphenylguanidine into the reaction kettle in sequence, and continue to stir at a low speed of 6-9r / s for 2-6 hours to extend the chain and vulcanize to obtain the polyurethane rubber. liquid. The heat resista...

Abstract

The invention relates to a polyurethane adhesive liquid specifically applicable to production of a popcorn-like shoe material. The adhesive liquid comprises the following preparation raw materials byweight: 38 to 45 parts of trimethylolethane, 22 to 28 parts of ethyl diisocyanate cyclohexane, 3 to 6 parts of diphenyl guanidine, 8 to 12 parts of dicarboxymethylpropionic acid, 3 to 6 parts of monoethanolamine, 4 to 6 parts of ammonium polyacrylate, 5 to 7 parts of propylene diamine, 0.5 to 2 parts of diethyl thiotoluenediamine, 3 to 6 parts of alkylene ether, 17 to 20 parts of acetone, 1 to 3 parts of acetyl tributyl citrate, 0. 5 to 1.5 parts of methyl tin mercaptide, 0.7 to 0.9 part of isopropyl titanate and 0.1 to 0.3 part of titanium dioxide. The polyurethane adhesive liquid provided bythe invention has heat resistance improved by 40 to 40% compared with the heat resistance of a majority of conventional polyurethane adhesive liquids, can still maintain good conventional performances at an ambient temperature of 95 to 115 DEGC, is insusceptible to generating adhesive failure and adhesive overflowing, and is especially applicable to products which require high-temperature treatment.

Description

technical field [0001] The invention relates to the field of polyurethane glue, in particular to a polyurethane glue especially suitable for the production of popcorn shoe materials and a reaction kettle thereof. Background technique [0002] The production of popcorn soles is formed by foaming TPU particles to obtain popcorn particles and bonding the popcorn particles together with a PU (polyurethane) adhesive. Polyurethane adhesives refer to adhesives containing carbamate groups (-NHCOO-) or isocyanate groups (-NCO) in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanate and polyurethane. Polyisocyanate molecular chains contain isocyano groups (-NCO) and carbamate groups (-NH-COO-), so polyurethane adhesives exhibit high activity and polarity. [0003] However, the heat resistance of polyurethane glue currently on the market is mostly between 70 and 85°C, but such heat resistance cannot meet the needs of many fields. Under these co...
