Abstract

The invention relates to a surface treatment agent for treating glass fabrics and a preparation method thereof. The surface treatment agent is prepared from the following ingredients including 0.52 to 0.65 weight percent of glacial acetic acid, 0.64 to 0.92 weight percent of silane coupling agents prepared by taking trialkoxysilanes as intermediates, 1.27*10<-3> to 2.27*10<-3> weight percent of auxiliary agents A, 5.45*10<-3> to 8.68*10<-3> weight percent of auxiliary agents B and the balance of pure water, wherein the auxiliary agents A are prepared from 40 to 55 weight percent of mineral oil, 25 to 40 weight percent of polyether, 15 to 25 weight percent of silicon dioxide and 2 to 5 weight percent of water; the auxiliary agents B are prepared from 60 to 75 weight percent of silicon oil, 15 to 25 weight percent of aliphatic hydrocarbon, 5 to 15 weight percent of polysorbate and 1 to 3 weight percent of water. The surface treatment agent has the advantages that through optimizing the formulas of the surface treatment agents, the proportion relationship between the formulas and the preparation method, the glacial acetic acid concentration in the surface treatment agents is obviously reduced; the raw material cost is saved; the corresponding waste water treatment cost is reduced; the general production cost of enterprises can be favorably reduced; the goal of protecting the environment is achieved.

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...
