Anti-falling cement-based glue for tiles for exterior wall

Abstract

The invention provides anti-falling cement-based glue for tiles for an exterior wall. The glue is prepared from the following components in parts by weight: 40-50 parts of common silicate cement, 45-55 parts of fine aggregate, 3-8 parts of filler, 1-3 parts of redispersible powder, 0.2-1.0 part of cellulose ether, 0.2-0.8 part of a water reducer, 0.3-1.0 part of crack-resisting fiber, 0.05-0.25 part of an anti-sliding compound, 0.05-0.25 part of a porosity regulating compound, and 0.2-1.0 part of a set controlling compound. According to the anti-falling cement-based glue for tiles for the exterior wall provided by the invention, the anti-sliding falling performance of an adhesive for tiles is improved simultaneously from four aspects of improving the binding power, resisting shrinkage crack, resisting slippage and enhancing the weather resistance; the construction properties of the glue for tiles such as water retention, viscosity maintaining and the like can be remarkably improved, the original adhesive strength of the glue for tiles can be effectively enhanced, and the tensile bond strength of the glue for tiles if the glue for tiles is soaked in water, thermally aged and frozen and thawed can be improved to a great extent. The glue for tiles has good adaptability with other additives. The glue for tiles plays good roles of reducing water and increasing strength, reducing the cracking risk and optimizing the gap structure,

Description

technical field

[0001] The invention belongs to the field of building materials, and in particular relates to an anti-shedding cement-based tile adhesive for exterior walls. Background technique

[0002] As a decorative material, ceramic tiles are widely used in both indoor and outdoor decoration. In exterior wall decoration, there are many ways to use large tiles to enhance the decorative aesthetics, especially in medium and high-end public buildings. However, with the rapid development of cities and the increase of high-rise buildings, it is not uncommon for exterior wall tiles to slip and fall off in large areas and smash cars and injure passers-by.

[0003] On the one hand, the sliding and falling off of exterior wall tiles is due to the increasing area and weight of single tiles used for exterior walls in my country. For example, the application of heavy-duty tiles of 800×800mm in the market has become very common; on the other hand, tiles are becoming more and more de...
