Abstract

The invention discloses ZnO nanomaterial hybridized acrylic emulsion, polyacrylic copolymer emulsion water-based paint, a waterproof roll and a preparation method of the polyacrylic copolymer emulsionwater-based paint. The ZnO nanomaterial hybridized acrylic emulsion is prepared from the raw materials in parts by weight: 1-8 parts of acrylic acid, 12-18 parts of butyl acrylate, 20-25 parts of methyl methacrylate, 0.10-0.30 part of an initiator, 0.1-1 part of a dispersing agent, 1.5-3.0 parts of nano ZnO, 45-65 parts of water, 1-2 parts of an emulsifier, 0-10 parts of styrene, and 0-10 parts of acrylonitrile. As an n-type semiconductor compound, the nano ZnO can absorb energy of short-wave light radiation higher than the energy gap of the nano ZnO to generate electron transition and corresponding holes, and can transmit the energy to surrounding dielectrics, and thus the bonding performance of the waterproof roll in poured concrete is protected when the waterproof roll is exposed to the ultraviolet environment for a long time.

Description

technical field [0001] The invention belongs to the field of building waterproofing, and more specifically relates to a ZnO nanomaterial hybrid acrylic emulsion, a polyacrylic acid copolymer emulsion water-based coating, a waterproof coiled material and a preparation method thereof. Background technique [0002] Polymer self-adhesive film waterproofing membrane is a composite waterproofing membrane with a multi-layer structure, usually including a main waterproofing layer and a pressure-sensitive adhesive layer. This kind of waterproof membrane can form a complete and continuous bond with the post-cast concrete after it is cured, and can effectively prevent water channeling between the waterproof membrane and the structural concrete layer. During the application process of this type of waterproof membrane, it usually needs to be pre-laid or fixed on the base concrete. For the actual application of materials in building floor engineering, it is difficult to strictly control ...
