Problems solved by technology

[0002] Glass fiber mesh cloth is based on glass fiber woven fabric, which is coated with polymer anti-emulsion. Because the acrylic emulsion used in glass fiber mesh cloth has "hot sticky and cold brittle" strength and The low retention rate of alkali resistance is limited in actual production and application, and the high temperature resistance, alkali resistance and erosion resistance are poor; and glass fiber mesh cloth has been widely used as a reinforcing material for building walls However, the strength of the existing mesh cloth cannot meet the needs of the construction industry. If thicker fibers are used, the surface of the mesh cloth will be uneven, poor in conformity, difficult to construct, insufficient in strength, and difficult to control in quality

Embodiment 1

[0014] A kind of preparation technology of glass fiber grid cloth, comprises the following steps:

[0015] (1) Gray cloth weaving: several raw yarns prepared from original sodium borosilicate glass are divided into warp threads and weft threads, and the two warp threads and weft threads are cross-woven into a warp thread group, and the warp thread groups are arranged equidistantly. Sequentially it is woven into a qualified grid gray cloth, wherein the warp is the round glass fiber yarn of 265g / km; the weft is 1265g / km, the wide flat glass fiber yarn of 3mm;

[0016] (2) Acid leaching: Arrange the above-mentioned gray cloths evenly on a group of support rods, put the whole into the acid leaching tank, select hydrochloric acid with a concentration of 3.0mol / L and inject it into the acid leaching tank. Treat for 2.8 hours, and at the same time use an acid-resistant pump to circulate and stir;

[0017] (3) Water washing: the gray cloth after the above steps is washed at a tempera...

Abstract

The invention belongs to the technical field of heat preservation building materials and particularly relates to a preparation process of a glass fiber mesh cloth. The preparation process comprises the following five steps: weaving a blank cloth, acid-leaching the blank cloth, water-washing the blank cloth, thermal-treating the blank cloth and performing after surface treatment. The glass fiber mesh cloth has compact tissue structure and flat and smooth surface, is low in thickness and variable coefficient of grams per square meter, has excellent high-temperature-resistant performance, has good flexibility and good fitness, is low in cost, and can be widely used in heat preservation, water proofing, crack resistance for inner and outer wall bodies of buildings.
