Embodiment

[0006] Embodiment: A kind of polyurethane paint synthesis technique is characterized in that: it is after being allocated by curing agent and water, is added dropwise in the coating, and the ratio of curing agent and water allocation is 1: 1 to 30 times or 1: 5 to 15 times, and can also be freely allocated, preferably 1: 8 to 10 times, more preferably 1: 8.6 to 9 times, the curing agent is isophorone diamine, water can be purified water or demineralized water, the most The best choice is pure water or demineralized water. The temperature of paint, curing agent and water should be controlled at 35°C-0°C or 20°C-0°C when adding drops, and the best control is at 15°C-0°C. The best solution is to control the temperature at 10°C-0°C. The speed of dropping should be determined by the time of uninterrupted dropping. Its time is 50-100 minutes, the best is 70-90 minutes, and the best choice is 75- 85 minutes, the most appropriate time is about 80 minutes, no more than 3 minutes, the b...

Abstract

The invention discloses a synthesizing technique of polyamine ester paint, which comprises the following steps: allocating isophorone diamine and softened water to drip into the paint; setting the ratio of allocating hardener and water at 1: 8.6-9; controlling the temperature of paint, hardener and water at 10-0 deg. c and the dripping time for 80 min; selecting shower dispersion dripping pattern. The invention simplifies the manufacturing technique without stock easily, which improves the manufacturing efficiency and reduces cost with easy spread and widely using.

Description

technical field [0001] The invention relates to a synthesis process of polyurethane paint. Background technique [0002] The production technology in the general polyurethane coating synthesis is not easy to master, it is easy to cause bad materials, the production efficiency is low, the cost is increased, and it cannot be popularized, so that it is widely used in production and life. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned defective, a kind of polyurethane paint synthesis technique is provided. [0004] The technical solution of the present invention is: a polyurethane coating synthesis process, characterized in that it is formulated by curing agent and water, and then added dropwise to the coating, the ratio of curing agent and water is 1:1 to 30 times Or 1: 5 to 15 times, also can allocate at will, preferably 1: 8 to 10 times, more preferably 1: 8.6 to 9 times, curing agent is isophorone diamine, water can ...
