Ceramic tile adhesive and preparation method thereof

Abstract

The invention discloses a ceramic tile adhesive and a preparation method thereof. The ceramic tile adhesive is prepared from the following raw materials in parts by weight: 30-40 parts of cement, 35-40 parts of quartz sand, 10-15 parts of vinyl acetate-ethylene copolymer rubber powder, 5-7 parts of zeolite powder, 0.3-0.6 part of nano titanium dioxide, 6-10 parts of modified gypsum powder, 1-3 parts of cellulose ether, 5-10 parts of fly ash, 0.3-0.6 part of setting retarder, 0.5-0.8 part of defoaming agent, 0.3-0.5 part of organic silicon water repellent, 4-7 parts of citric acid, 5-8 parts of guar gum, 3-7 parts of eucalyptus oil, 2.6-3.5 parts of rice bran wax and 50-70 parts of water. The ceramic tile adhesive has the advantages of favorable water resistance, favorable cold / heat abrupt change resistance, favorable aging resistance and favorable long-term durability, and has high binding force with ceramic tiles when being used for bonding ceramic tiles.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a ceramic tile adhesive and a preparation method thereof. Background technique [0002] Ceramic tile facing system is one of the most commonly used decorative facings in my country's construction projects; it has the characteristics of strong impact resistance, good durability, and easy cleaning; but it is often accompanied by several stubborn problems such as water seepage, hollowing, and shedding . At present, the commonly used bonding and caulking materials for tile facing in China include: pure cement slurry, cement mortar, flexible tile adhesive, silica gel, etc. These materials have a high water absorption rate, which will generate strong thermal expansion internal stress in the hot summer and severe cold winter. The freezing of the system after absorbing water will also generate strong expansion internal stress. There is a problem of cracks due to expansion and ...

Problems solved by technology

These materials have a high water absorption rate, which will generate strong thermal expansion internal stress in the hot summer and severe cold winter. The freezing of the system after absorbing water will also generate strong expansion internal stress. There is a problem of cracks due to expansion and contraction caused by temperature changes. These Internal stress destroys the bonding interface, resulting in hollowing and falling off
