Problems solved by technology

[0005] In the above application documents, the epoxy floor coating can be applied under the condition of 0°C without freezing and has excellent product performance. It can solve the problems of slow reaction, incomplete reaction or even freezing of existing coatings in low temperature environments, making the floor At the same time, the floor has high wear resistance, crack resistance and hardness, etc., but the floor coating is mainly made of solvent-based epoxy materials with conductive additives. During long-term use, the overall antistatic effect is not durable. problems, and the overall application effect is not good, therefore, a new solution needs to be proposed to solve the above problems

Abstract

The invention discloses solvent-free epoxy self-leveling antistatic finish paint and a preparation method thereof and relates to the technical field of epoxy self-leveling paint. The problems that theantistatic endurance performance of the floor coating is poor; the solvent-free epoxy self-leveling antistatic finish paint comprises a component A and a component B, the component A and the component B are independently stored and mixed according to the weight part ratio of (4-6): 1 in use, and the component A comprises the following raw materials in parts by weight: 25-35 parts of bisphenol A type epoxy resin; 1.2 to 1.6 parts of a reactive diluent AGE; 1.4 to 1.8 parts of benzyl alcohol; 0.8 to 1.2 parts of a Disponer 9250 wetting and dispersing agent; 0.3 to 0.5 part of a defoaming agent;0.5 to 0.7 part of leveling agent; 0.8 to 1.2 parts of wax powder; 0.6 to 0.9 part of an anti-settling agent; 45 to 50 parts of silicon barium powder; 8 to 12 parts of epoxy color paste; 3-6 parts ofconductive graphene; 2.5 to 5.5 parts of a conductive auxiliary agent; 1.8 to 2.6 parts of hexadecyl trimethyl ammonium bromide; and the component B is a polyether amine curing agent. The solvent-free epoxy self-leveling antistatic finish paint provided by the invention has stable and lasting antistatic performance.

Description

technical field [0001] The invention relates to the technical field of epoxy self-leveling paint, more specifically, it relates to a solvent-free epoxy self-leveling antistatic paint and a preparation method thereof. Background technique [0002] Floor coatings are ground decoration materials that use epoxy resin raw materials as the main agent, adding pigments, solvents, and auxiliary curing agents. The research and production of epoxy oily floor paints all become floor coatings. [0003] Factory floor coatings generally contain high-insulation polymer materials. When the surface is rubbed or impacted, it is easy to generate and accumulate static electricity, which will cause electromagnetic interference. What is more serious is that when static electricity accumulates to a certain extent, it will generate static electricity. Discharge will cause flammable and explosive materials to ignite or explode, causing huge and vicious accidents. Therefore, floor coatings need to hav...
