Anti-static epoxy self-leveling coating material

Abstract

The invention relates to an anti-static epoxy self-leveling coating material which comprises the following components in percentage by weight: 30-50 percent of bisphenol A epoxy resin, 1-5 percent of a reactive diluent, 5-20 percent of a conductive filler, 0.1-0.2 percent of a dispersing agent, 1-3 percent of a leveling agent, 0.1-0.5 percent of a defoaming agent, 5-10 percent of a curing agent and 20-50 percent of water. A preparation method of the anti-static epoxy self-leveling coating material comprises the following steps: (1) adding the reactive diluent into the bisphenol A epoxy resin, and stirring for 20min at a constant speed; (2) adding the conductive filler, the dispersing agent, the leveling agent and the defoaming agent into a mixture prepared in step (1), dispersing for 30min at a high speed, and grinding to obtain slurry; (3) mixing the curing agent and water, and stirring for 20 min at a constant speed to form a water solution; and (4) adding the slurry prepared by grinding into the curing agent water solution prepared in step (3), and mixing uniformly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antistatic epoxy self-leveling coating. Background technique [0002] With the development and production of modern science and technology, more and more factories and workshops have put forward the requirement of eliminating static electricity accumulation for floor paint, which makes the status of anti-static epoxy floor paint increasingly prominent. However, the antistatic performance of the antistatic floor paint currently on the market is very limited, which is far from meeting the requirements for use. [0003] Conductive fillers are an important part of additive antistatic coatings, and it is necessary to select the appropriate type, shape and amount of conductive fillers. Commonly used conductive fillers include metal-based fillers, carbon-based fillers, metal oxide-based fillers, and composite conductive fillers. Metal-based fillers have disadvantages such as high ...

AI Technical Summary

Problems solved by technology

Metal-based fillers have disadvantages such as high price or poor oxidation resistance; carbon-based fillers also have problems such as poor dispersion stability and single color; metal oxide-based fillers have not been widely used due to technical and cost problems; composite conductive fillers are easy to settle and harden, and high-speed The conductive material coated on the surface is easy to peel off when dispersed, resulting in unstable antistatic performance of the coating, and contains tin, antimony, indium and other heavy metals that are harmful to the human body, which do not meet the increasingly stringent environmental protection requirements
