Abstract

The invention relates to the field of water-based paint, and particularly discloses a water-based epoxy anti-static self-leveling floor finish paint composition and a construction method. The waterborne epoxy anti-static self-leveling floor finish paint composition is composed of a component A and a component B. The component A is prepared from, by weight, 30-50 parts of waterborne epoxy resin emulsion, 1-10 parts of carbon nanotube conductive paste, 10-30 parts of filler, 1-10 parts of auxiliaries, 1-5 parts of waterborne color paste and 10-30 parts of water. The carbon nano tube in the carbon nano tube conductive slurry is obtained by reacting polysiloxane with double-end hydroxyalkyl side chain polyether and an epoxy group with an acylating chlorination carbon nano tube. The waterborne epoxy anti-static self-leveling floor finish disclosed by the invention can realize better and stable anti-static performance under the condition of lower carbon nanotube content.

Description

technical field [0001] The application relates to the field of water-based coatings, more specifically, it relates to a water-based epoxy antistatic self-leveling floor topcoat composition and a construction method. Background technique [0002] Due to its environmental protection characteristics, water-based floor paint is currently used on a large scale. However, the main film-forming substance of the floor topcoat is epoxy resin, which has good insulation, and the topcoat will be frequently rubbed (for example, the topcoat in the garage often rubs against the wheels), resulting in the formation of static electricity. Effective and rapid conduction can lead to static electricity accumulation and cause danger. [0003] Carbon nanotubes have a large aspect ratio and are an excellent conductive material. Now they are widely used in water-based floor paints. However, in the existing application methods, carbon nanotubes are easy to disperse, aggregate, and disperse The probl...
