Abstract

The invention relates to the technical field of construction materials, particularly an improved adhesive for reinforcing glass fiber meshes for bonding stones. The adhesive is formed by mixing a liquid component and a powder component. The liquid component comprises a mixed emulsion, water and a defoaming agent. The powder body component comprises cement, quartz sand, cellulose ether, a water reducing agent and a retarder. The weight ratio of the liquid component to the powder component is 1:3-1:5, and the viscosity of the finished product is 20000-60000cp. The adhesive is simple to prepare; the added water reducing agent and retarder can shorten the drying time by 40-50%; and the viscosity change of the slurry is controlled within a narrower range, thereby greatly enhancing the production efficiency and quality uniformity of the reinforcing glass fiber meshes for bonding stones. The ratio of the liquid component to the powder component is enhanced, so that the use cost is greatly lowered by 30-40%. The adhesive has the advantages of proper setting time, short drying time, narrow viscosity change range, high production efficiency and lower cost, and is beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an improved adhesive for pasting stone reinforced glass fiber nets. Background technique [0002] Stone is a good decorative material, which has been widely used in architectural decoration and has good decorative effect. However, the anti-bending and anti-bending strength of decorative stone is not high enough. In actual use, it is necessary to paste glass fiber mesh cloth on the back of the stone for reinforcement. The commonly used bonding materials are epoxy resin, unsaturated resin, stone waterproof adhesive, etc. . Stone waterproof adhesive, which can meet the bonding performance and decorative effect of the back of the stone. Applying the waterproof adhesive to the back of the stone can form a very good waterproof layer, and the waterproof layer has a good relationship with the cement-based adhesive. compatibility and durability. [0003] However, the existin...
