Abstract

The invention discloses a high molecular polymer emulsion and a preparation method thereof, a functional coating, a film layer and a waterproof roll material. The raw materials of the polymer emulsion include methacrylic acid, methyl methacrylate, and selective butyl methacrylate. Esters, initiators, emulsifiers, catalysts and water, the mass ratio of methacrylic acid to methyl methacrylate is 1:0.8-1.4; and made by emulsion polymerization method; the functional coating comprises the above-mentioned emulsion and functional additives; The film layer is made of the above-mentioned emulsion or functional coating; the above-mentioned emulsion or functional coating can be directly coated on the surface of the waterproof coil material or directly cover the surface of the waterproof coil material by using the above-mentioned film layer, and then a polymer containing the present invention is made. The high-molecular polymer can react with cement mortar or post-cast concrete, which enhances the effective adhesion, thereby ensuring that the waterproofing membrane provided with the high-molecular polymer and the substrate are fully bonded.

Description

technical field [0001] The invention belongs to the field of construction engineering waterproofing, and specifically relates to a high molecular polymer emulsion and a preparation method thereof, a functional coating, a film layer and a waterproof roll material. Background technique [0002] Now waterproofing membranes include wet-laid waterproofing membranes and pre-laid waterproofing membranes, but no matter which type of materials there are some obvious problems and defects, for example, SBS has been combined with non-curing coatings in recent years to solve the problem of SBS. There is a problem that the coil and the base surface are full of stickiness, but during construction, non-curing needs to be heated and melted, and the SBS base film also needs to be baked, which is easy to cause fire. For self-adhesive materials such as PET and cross-laminated film materials, the choice of isolation film is a problem. First, the isolation film forms white pollution on the constr...
