Abstract

The invention discloses a styrene copolymer emulsion for dip coating of glass fibers and a preparation method and an application of the styrene copolymer emulsion. In order to solve the problem that the glass fibers subjected to dip coating are low in alkali resistance in the prior art, the styrene copolymer emulsion is prepared by taking a certain quantity of styrene, acrylonitrile and acrylate as a mixed monomer, selecting a specific seed emulsifier and a blended emulsifier, adopting a seed emulsion, and performing polymerization. The styrene copolymer emulsion is good in stability; and the glass fibers treated by using the styrene copolymer emulsion are straight, good in alkali resistance and high in fiber strength.

Description

technical field [0001] The invention relates to a styrene copolymer emulsion, in particular to a styrene copolymer emulsion used for glass fiber dip coating and its preparation method and application. Background technique [0002] The main raw materials of glass fiber are natural ores such as limestone, silica, alumina, fluorite, etc., which have excellent properties such as high temperature resistance, corrosion resistance, high strength, small specific gravity, low moisture absorption, and good electrical insulation performance; glass fiber as a Widely used reinforcing material, can be used in plastic products, construction, aerospace, microelectronics and other fields, especially the mesh cloth made of glass fiber, can be used in building exterior wall insulation system, roof asphalt waterproof, etc., is a kind of New building materials. [0003] Yu Zhongying disclosed an emulsion adhesive in the article "Development of Emulsion Adhesive for Glass Fiber Mesh Cloth", whic...
