Abstract

The invention discloses a preparation method of a quick-drying high-bonding-strength ceramic tile adhesive, and belongs to the field of building materials. A mixed glue solution is prepared by blending carboxymethyl chitosan, guar gum and the like, a pretreated glue solution containing microsphere components is formed under the cross-linking effect of auxiliary materials, and a concentrated material containing titanium dioxide prepared subsequently is combined to provide a catalytic drying effect, improve the dispersion stability of a ceramic tile glue, provide good bonding strength, added sugar calcium facilitates internal polymerization, and calcium ions can be combined with sodium alginate to mask part of hydrophilic groups to form a relatively stable egg box structure to provide the function of separating water, so that the time required for solidification is shortened, and the bonding strength is maintained for a long time. According to the invention, metakaolin is modified by trimethylchlorosilane to construct a hydrophobic film, so that part of methyl groups can replace hydroxyl groups, the number of hydrophilic silicon hydroxyl groups is reduced, and the compatibility withrubber materials is improved. The method solves the problems of long solidification time and low bonding strength of the common ceramic tile adhesive at present.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of quick-drying high-bonding strength tile adhesive. 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 a single tile for exterior walls. For example, the application of 800×800mm heavy-duty tiles in the market has become very common; on the other hand, tiles are becoming denser and more absorbent ...
