Abstract

The invention relates to an acrylate tile back glue emulsion and a preparation method thereof. The preparation method comprises preparation of a base material liquid A, preparation of a monomer solution B, preparation of an initiator solution C, preparation of a later added initiator solution D, pre-emulsification semi-continuous dropwise addtion, and later treatment processes. The emulsion comprises, by weight, 100 to 500 parts of an alkyl acrylate monomer, 20 to 100 parts of an alkyl methacrylate monomer, 0.1 to 10 parts of alkyl carboxylic acid, 1 to 10 parts of a functional monomer, 0.1 to 10 parts of vinyltrioxysilane, 1 to 30 parts of an emulsifier, 0.1 to 5 parts of an initiator, 0.1 to 5 parts of a buffering agent, and 100 to 150 parts of deionized water. The preparation method has the advantages of simple processes, low cost and safety. The emulsion has characteristics of good gloss, good water resistance, good weather resistance, high peel strength, high adhesion and instant-coating and instant-pasting of a single component.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and relates to an emulsion for acrylic tile back glue and a preparation method thereof. Background technique [0002] Tile back glue can effectively improve the bonding strength between the back of the brick and the bonding material, and solve the common problems of hollowing, peeling, and falling off of the wet tile in the decoration project. It is the most effective interface bonding reinforcement material at present. . Tile adhesives are mainly used to paste decorative materials such as ceramic tiles, facing tiles, and floor tiles, and are widely used in decorative decoration places such as interior and exterior walls, floors, bathrooms, and kitchens. Its main features are high bonding strength, water resistance, freeze-thaw resistance, good aging resistance and convenient construction. It is a very ideal bonding material. [0003] However, although the tile adhesives currently on the...
