Abstract

The invention relates to a preparation method of a surface coating treating agent capable of improving the strength of a phosphate strengthened quartz fiber composite material and a coating treatment method, and relates to a preparation method of a surface coating treating agent for phosphate strengthened quartz fiber composite material and a coating treatment method. In order to solve the problems that the phosphate strengthened quartz fiber composite material prepared by using coating anticorrosive treatment in the existing method is bad in mechanical properties at normal temperature and high temperature, the treating agent is prepared by dissolving thermosetting phenolic resin in ethanol so as to obtain the surface coating treating agent. The preparation method comprises the following steps of: immerging quartz fiber in the surface coating treating agent for soaking; and airing after taking out so as to complete the coating treatment. The preparation method of the treating agent is simple, and the coating treatment method is simple; for the phosphate strengthened quartz fiber composite material prepared by taking the quartz fiber after being treated as a base material, the bending strength at the normal temperature reaches to 300MPa, and reaches to 124MPa at 500 DEG C; and the phosphate strengthened quartz fiber composite material can be applied to the high temperature resistance fields of aviation, aerospace, and the like.

Description

technical field [0001] The invention relates to a preparation method and a coating treatment method of a surface coating treatment agent for a phosphate-reinforced quartz fiber composite material. Background technique [0002] In the phosphate-reinforced quartz fiber composite material, due to the strong corrosiveness of phosphate to silica, the quartz fiber without surface coating will react with quartz to form silicic acid during the phosphate curing process due to high temperature and acidic conditions. Severely corrodes the quartz fiber, resulting in a serious decline in the mechanical properties at room temperature and high temperature. [0003] Various methods are used in China for coating anti-corrosion treatment, such as: silicone resin, alumina sol-gel, zirconia sol-gel, etc., but the anti-corrosion effect is not good. The bending strength is lower than 60MPa, and the mechanical properties at room temperature and high temperature are poor, so it is not suitable for...
