Abstract

The invention relates to the technical field of preparation of building materials and in particular relates to a method for preparing two-component vitrified brick backing glue. The method disclosed by the invention comprises the following steps: treating sugarcane serving as a raw material to obtain pre-dispersed suspension, mixing the pre-dispersed suspension, cotton stalk bark fibers, ammoniumpersulfate, N,N-methylenebis acrylamide and the like, reacting, extracting with acetone, drying to obtain a component A, performing graft copolymerization on acrylic acid and sugarcane fibers, forminga three-dimensional network structure, and producing a water-absorbent resin, wherein the cotton stalk bark fibers easily crimp when meeting water, the water is difficultly squeezed out, the roughness of the vitrified brick can be improved by the cotton stalk bark fibers, and the bricks are conveniently adhered; mixing a cellulose ether and a castor oil polyurethane prepolymer, dispersing to obtain premixed emulsion, adding quick lime, carboxylic butadiene-styrene latex, fly ash and other materials into the pre-dispersed mixture, performing vacuum defoamation to obtain a component B, and performing network interpenetrating on castor oil polyurethane and methyl silicone rubber, thereby obtaining an adhesive with an IPN (Interpenetrating Polymer Network) structure. The network interpenetrating structure is compact in binding, and the application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a method for preparing a two-component back glue for vitrified tiles. Background technique [0002] At present, ceramic bricks with high water absorption rate (5% to 10%) used in home decoration, large clubs, supermarkets and interior and exterior decoration of buildings have low strength, single style, and small size, so they are no longer suitable for high-speed development. market needs. At the same time, vitrified bricks have been widely used in the architectural decoration market due to their advantages of low water absorption, high strength, and many specifications and varieties. [0003] Vitrified tiles are commonly known as porcelain polished tiles. Vitrified tiles are made of quartz sand and mud fired according to a certain proportion, and then polished brightly but do not need to be polished. The surface is as smooth and translucent as a glass mir...
