Abstract

The invention discloses an all-purpose back gum which comprises a styrene-acrylic emulsion, a polycarboxylic acid water reducer and a butyl acrylate emulsion, and the mass ratio of the styrene-acrylic emulsion to the polycarboxylic acid water reducer to the butyl acrylate emulsion is 3:(0.1-0.2):(1.8-2.3). The butyl acrylate emulsion is prepared from the following raw materials in parts by weight: 30 to 40 parts of butyl acrylate, 0.1 to 0.5 part of polyvinyl alcohol, 10 to 15 parts of butadiene, 2 to 5 parts of acrylic acid, 6 to 10 parts of a surfactant, 0.1 to 0.5 part of an initiator and 40 to 50 parts of water. According to the back gum disclosed by the invention, the defects in the prior art are overcome. When the back gum is applied to coatings of cement outer walls, inner walls and floors, the waterproof and anti-falling effects can be achieved, the durability is prominent, and the back gum can be firmly combined with cement.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an all-round adhesive. Background technique [0002] With the progress of society and the continuous development of science and technology, there are many kinds of waterproof coatings, which can be divided into silicone self-cleaning and water-resistant coatings, strong acid and alkali resistant coatings, pure acrylic elastic coatings, tempered waterproof putty powder, silicone self-cleaning elastic coatings, Fluorocarbon coatings, advanced acrylic coatings, exterior wall paints, special primers for tiles, environmentally friendly exterior wall latex paints, tile topcoats, acrylic oily topcoats, high weather-resistant hydrophobic topcoats, metallic paints and other coatings with different functions. Also known as glue. Due to the wide variety of these glues, construction workers need to use a variety of waterproof glues in the process of building construction, which makes the c...
