Alkali-resistant glass fiber mesh cloth

Abstract

The invention discloses alkali-resistant glass fiber mesh cloth. The mesh cloth is formed by weaving longitude lines and latitude lines, wherein all the longitude lines are arranged longitudinally atequal distance, all the latitude lines are arranged horizontally at equal distance, and each of the longitude lines is woven with all the latitude lines; all the longitude lines and all the latitude lines are glass fiber yarns, each of the glass fiber yarns comprises a plurality of monofilaments, and the diameter of each of the monofilaments is 7-10 [mu]m; the thickness of the alkali-resistant glass fiber mesh cloth is 0.2-0.7 mm; and the outer surface of the alkali-resistant glass fiber mesh cloth is coated with a binding agent layer, and the outer surface of the binding agent layer is coatedwith an alkali-resistant layer. The alkali-resistant glass fiber mesh cloth is strong in high temperature resistance, high in tensile strength and low in thermal conductivity coefficient; in addition, when the alkali-resistant glass fiber mesh cloth is compounded with resin to form an anti-ablation material, the anti-ablation property and the mechanical washing resistance of the anti-ablation material can be effectively improved, and high temperature on the surface of the anti-ablation material can be prevented from transmitting into the anti-ablation material.

Description

technical field [0001] The invention relates to a mesh cloth, in particular to an alkali-resistant glass fiber mesh cloth. Background technique [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; [0003] Glass fiber mesh cloth is often used in building decoratio...

[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;

[0003] Glass fiber mesh cloth is often used in building decoration, and it is pasted on the wall to prevent cracking of the wall surface. Generally, only one layer of mesh cloth can be pasted on the wall, but there are special cases, such as at the lap joint Or wh
