Description
Technical Field
The invention belongs to the technical field of tile bonding materials, and particularly relates to a reaction-curing organic-inorganic composite elastic multi-component tile bonding material and a preparation method thereof.
Background
With the rapid development of modern society, people have higher requirements on living environment, so that not only safety and durability of buildings, but also comfort and attractiveness are required to be ensured. The ceramic tile is used as an important decorative material, and has the advantages of good appearance, good waterproof property, high hardness, easy cleaning, green environmental protection and the like, is favored by people, and the use amount in the decoration industry is gradually increased, so that the demand of the market for ceramic tile glue is also gradually increased. At present, common tile bonding materials in the market include common cement mortar, tile adhesive, pressure-sensitive adhesive and tile back adhesive.
The pressure-sensitive adhesive is prepared from high-molecular polymer emulsion, defoamer, dispersing agent and other auxiliary agents, and when in use, the pressure-sensitive adhesive is coated on the back of the ceramic tile, and the ceramic tile is paved and stuck on the upper wall of the cement mortar. After the pressure-sensitive adhesive is coated, a layer of milky film is formed on the surface after 2-3 hours, so that the ceramic tile can be paved, or the construction period is too long, the pressure-sensitive adhesive has poor water resistance, or the ceramic tile is fallen off due to low bonding strength. The tile back adhesive is a product compounded by high molecular polymer emulsion and electrodeless silicate, and is coated on the back of the tile as the same as the pressure sensitive adhesive and then covered with cement mortar for paving the wall. Compared with pressure sensitive adhesive, the tile back adhesive does not need to be dried and has better water resistance. But the tile adhesive back adhesive is troublesome in construction, has a slightly high price and is not suitable for large-area use.
Because the pressure-sensitive adhesive and the tile back adhesive are both troublesome in construction, can not be used independently, and have high price. Currently, the commonly used tile bonding materials are still conventional cement mortars and tile adhesives. The common cement mortar mainly comprises cement and sand, belongs to brittle materials, has the defects of low bonding strength, large dry shrinkage deformation, poor impermeability, poor corrosion resistance and the like, cannot resist displacement deformation caused by thermal expansion and contraction or wet expansion and dry shrinkage, and easily causes tile falling. The tile adhesive is cement mortar modified by the polymer, and has the advantages of low brittleness, high bonding strength, high durability, high corrosion resistance and the like compared with cement mortar. But domestic concrete wall roughness is not enough, in order to make the ceramic tile wall level and beautiful, only can adopt thick subsides method construction, guarantees the roughness through improving thickness. And the main component of the tile adhesive is cement, and the hydration reaction can lead to volume shrinkage, so that the tile is empty and falls off. Although the tile adhesive has certain flexibility, the tile adhesive has no extensibility, and is easy to crack and cause bonding failure when deformed. In addition, the tile glue needs to be maintained for a period of time after construction to reach the bonding strength peak value, and the lower the temperature is, the slower the hydration reaction is, and the later the bonding strength peak value appears.
Besides the defects of the bonding material, the ceramic tile and the bonding material are deformed due to the change of the environment dry and wet and the temperature; the building subsides or deforms and then leads to bonding failure between bonding material and ceramic tile, between bonding material and basic unit, finally drops, and damage to personnel building is all very big. In addition, the water absorption and the size of the ceramic tile also cause the problems of brick falling and the like. The lower the water absorption of the tile, the higher the requirement for the adhesive strength of the tile glue. The larger the tile size, the fewer the tile seams per unit area, the smaller the seams available for deformation, and the tile is more likely to fall off. Tile drop has become a problem to be solved in the industry.
