Problems solved by technology

[0003] However, the known pigments are injected and kneaded with liquid raw materials such as isocyanate polymers and hydroxyl compounds at the same time. Since the general kneading process will generate high temperatures due to high pressure, the pigments are easily affected by high temperatures. Discoloration, and its color cannot achieve the expected bright effect, which finally affects the quality of the resin film produced and coated

Abstract

A process for preparing resin membrane includes such steps as mixing isocyanate polymer with hydroxy compound, adding pigment and foaming agent, pugging, and coating it on a cloth substrate.

Description

technical field [0001] The present invention relates to a kind of resin, more specifically, it refers to a method of premixing the raw materials that make up the resin, then adding coloring material and foaming agent for secondary mixing, and finally coating to form a resin film , so that it retains its original color and better vividness. Background technique [0002] Press, the general resin film is formed by coating the reactive resin on the base cloth by using the coating equipment, wherein, the reactive resin is composed of an isocyanate polymer containing NCO - referred to as PU resin, an OH-containing Two liquid raw materials of hydroxyl compound, one color material and one foaming agent are simultaneously injected into a kneading and mixing mechanical equipment for kneading and mixing with different stroke lengths, and finally, the mixture is injected into the coating equipment to form. [0003] However, the known pigments are injected and kneaded with liquid raw ma...
