Abstract

The invention discloses a preparation method of a fluorine functional monomer modified soap-free emulsion polymer for polymer cement. Hydroxyl monomers and ester monomers are used as raw materials; asoap-free emulsion polymerization method is adopted, meanwhile, a pH regulator is used for controlling the pH value of the reaction environment to be 8 to 8.5; the soap-free hydroxyl hydrophilic monomers, soap-free ester-based hydrophobic monomers and an initiator a are subjected to reaction to synthesize a soap-free polymer; the soap-free polymer reacts with other raw materials to synthesize a polymer waterproof coating. The preparation method has the advantages of high polymerization speed, fewer reaction steps, small environmental pollution and mild reaction conditions, and the synthesizedproduct has quite good adhesion force, tensile elasticity and durability with a basal plane due to the proper pH value in the polymerization process.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to the field of waterproof materials, in particular to a preparation method of a soap-free emulsion polymer modified with a fluorine functional monomer for polymer cement. Background technique [0002] With the continuous improvement of social living conditions, people pay more and more attention to their quality of life, and their requirements for waterproof conditions are constantly increasing. In recent years, with the development of social science and technology, new waterproof products and their engineering application technologies have developed rapidly, and are developing from multi-layer to single-layer, from hot construction to cold construction. Faced with the continuous progress and renewal of science and technology, it is particularly important to master the construction preparation and quality issues of waterproofing projects, which is of great significance to t...
