Problems solved by technology

However, this method is difficult to process and has high production costs, so it is not suitable for promotion.
In addition, the so-called air permeability only allows a small amount of water vapor to pass through, the internal and external air circulation is poor, and the air permeability is not ideal.

Abstract

The invention provides high-molecular large-mesh breathable and rain-proof mesh cloth and a processing technology thereof. The processing technology comprises the steps of firstly modifying porous inorganic particles through gamma-methacryloxypropyltrimethoxysilane to obtain modified porous inorganic particles; then taking cross-linked starch, acrylamide and the modified porous inorganic particles as raw materials, and carrying out a polymerization reaction to obtain a polymerization product; then uniformly mixing 2-methyl-1,3-pentanediol, polyester polyol, the polymerization product, ammonia water with the mass concentration of 5-7% and 1-aminoethyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide, then adding 4-methylcyclohexyl diisocyanate, and performing stirring and uniform mixing to obtain a coating solution; and finally, uniformly coating the outer surface of base cloth of polyvinyl chloride mesh cloth with the coating solution, and performing curing and drying to obtain the high-molecular large-mesh breathable and rain-proof mesh cloth. The rain-proof mesh cloth has both rain-proof performance and air permeability, and has good popularization value.

Description

technical field [0001] The invention relates to the technical field of rainproof fabric processing, in particular to a large-mesh polymer mesh breathable rainproof fabric and its processing technology. Background technique [0002] Rainproof tarpaulins are in great demand in real life, such as tarpaulins, raincoats, etc. The most basic requirement of rainproof tarps is to prevent rainwater, but the existing waterproof materials are impervious to water and also impermeable to air, and both tarpaulins and raincoats have certain requirements on air permeability. [0003] Due to the contradiction between water resistance and air permeability, if the water resistance of the product is good, the corresponding air permeability will be poor, and if the product has good air permeability, the corresponding water resistance will be poor. Therefore, how to balance rain resistance and air permeability is the biggest problem currently facing. [0004] In recent years, people have tried ...
