Problems solved by technology

Since most of the existing tile adhesives are rigid materials, there is not enough adhesion between the cement mortar and the tiles after molding, and the external environment (such as temperature changes, foundation or wall subsidence, cracks, external forces, etc.) Under the influence of different stresses and subtle movements, it is very easy to lose the original bonding force between the tiles and the bonding surface, resulting in hollowing and even the phenomenon of tiles falling off, which not only affects the environmental beauty of the building, but also It may threaten people's personal safety, and there are serious safety hazards

Abstract

The invention provides an elastic rock plate paving adhesive and a preparation method thereof. The elastic rock plate paving adhesive is prepared from the following raw materials: resin, aggregate, filler, functional filler, a water removal agent, a silane coupling agent, an accelerant and an additive, wherein the functional filler is hollow glass microspheres and/or hollow plastic microspheres. The paving adhesive does not need to be mixed when in use, can be used once a bag is opened, is used for paving rock plates, cement base surfaces, wood plates and the like, has good elasticity, can effectively absorb stress, and has light weight and heat insulation performance.

Description

technical field [0001] The invention belongs to the field of decorative materials, and relates to a paving adhesive, in particular to an elastic rock slab paving adhesive and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, adhesives are widely used, and people's requirements for adhesives are getting higher and higher. Low cost, strong security and other characteristics. But today's adhesives have high production costs and poor environmental performance. [0003] In recent years, with the rapid development of the construction industry, tile adhesives for pasting decorative materials such as ceramic tiles, facing tiles, and floor tiles have been widely used in interior and exterior walls, floors, bathrooms, kitchens and other building decorations. Since most of the existing tile adhesives are rigid materials, the cement mortar does not have enough adhesion between th...
