Abstract

The invention relates to a surface treating agent and a preparation method thereof. The surface treating agent is prepared from the following components in percentage by weight: 0.70 to 0.75 percent of glacial acetic acid, 0.45 to 0.55 percent of silane coupling agent prepared by taking trialkoxysilane as an intermediate, 0.33 to 0.40 percent of sulfur-containing silane, 0.75 to 1.00 percent of polyacrylamide, 0.55 to 0.89 percent of acid resin, 1.7 to 2.3 percent of emulsifier, 3.7 to 4.5 percent of higher alcohol, 1.27*10<-3> to 2.27*10<-3> percent of antifoaming agent, and the balance of pure water. The surface treating agent has the advantages that the formula, the mixture ratio and the preparation method of the surface treating agent are optimized, so that the concentration of the glacial acetic acid in the surface treating agent is lowered remarkably, the raw material cost is lowered, corresponding waste water treatment cost is lowered, the overall production cost of an enterprise is lowered, and the aim of protecting the environment is fulfilled; the surface treating agent disclosed by the invention has an unexpected effect of enhancing the mechanical performance of woven glass fabrics.

Description

technical field [0001] The present invention relates to a surface treatment agent, and more particularly, to a surface treatment agent for treating glass cloth and a preparation method thereof. Background technique [0002] Glass-fibre fabric is a kind of fabric made of glass fiber, which has the properties of insulation, heat insulation, corrosion resistance, non-combustion, high temperature resistance, high strength, etc. It is mainly used as insulating material and reinforcing material of FRP , chemical filter cloth, high-pressure steam insulation materials, fireproof products, high elastic transmission belts, building materials and wall coverings, etc. [0003] In order to make the glass cloth itself have better mechanical properties and be easier to apply to the composite process with other materials, it is necessary to carry out surface treatment on the glass cloth during the production process of the glass cloth. Since glass cloth is an inorganic fiber, a silane coup...
