Abstract

The invention belongs to the field of vitrified brick binders, and specifically provides a gypsum based vitrified brick binder and a preparation method thereof. The binder is prepared from following raw materials in parts by weight: 350 to 400 parts of alpha gypsum, 600 to 650 parts of graded sand, 1.5 to 3 parts of water retainer, 12 to 18 parts of redispersible latex powder, 0.15 to 0.3 part ofretarder, 5 to 8 parts of wood fibers, 5 to 10 parts of water repellent, and 0.8 to 1 part of starch ether. Alpha gypsum is taken as the main cementing material to prepare the vitrified brick binder,which has the characteristics of excellent binding performance, durability, stability, waterproof property, good construction performance, and shrinkage resistance. The shortages of a cement based binder such as bad stability, bad durability, and the like, are overcome. Moreover, the application range of gypsum is enlarged. The prepared vitrified brick binder has a sound absorbing property, a moisture absorbing performance, a flame retardant property, and a thermal insulation property.

Description

technical field [0001] The invention belongs to the field of vitrified tile adhesives, and specifically discloses a gypsum-based vitrified tile adhesive and a preparation method thereof. Background technique [0002] With the development of the ceramic industry and the improvement of people's requirements for the quality of ceramic tiles, ordinary ceramic tiles are gradually being replaced by high-quality vitrified tiles. Vitrified tiles are commonly known as porcelain polished tiles. A bright brick. Vitrified tiles are commonly used in specifications of 300*600mm, 600*600mm, and 800*800mm. The size is relatively large, and its water absorption rate is lower than 0.5%. The vitrified tile adhesive has been rapidly developed and applied to meet the requirements of bonding performance and prevent the occurrence of tile shedding events. At present, in the preparation of vitrified brick adhesives, cement is generally used as the cementitious component, graded sand is used as th...
