Problems solved by technology

[0002] At present, on the inner walls of various buried pipelines, sewage treatment pools, sewage tanks, cooling towers, wet gas storage cabinets, reservoirs, caverns and tunnels, asphalt-based epoxy coatings are usually used for anti-corrosion and anti-fouling purposes, but asphalt The composition contains heavy metals and other toxic and harmful substances, which are harmful to the environment and the human body. At the same time, epoxy asphalt coatings contain more solvents. In a closed environment on the inner wall, in addition to being harmful to the human body, there is also a danger of explosion; Therefore, there is a need in the market for an antifouling coating that is solvent-free, environmentally friendly, does not contain asphalt, has better anti-corrosion and anti-fouling properties, and has better one-time film-forming properties.

Abstract

The invention relates to an epoxy solvent free paint and a preparation method thereof. The paint comprises the following components and contents in parts by weight: 35-45 parts of epoxy resin, 10-20 parts of curing agent, 30=45vparts of inert pigment filler, and 5-10 parts of additive. Compared with the prior art, the solid content of the epoxy solvent free paint in the invention is 100%, VOC content thereof is 0, and solvent evaporation does not exist, environment protection property is good, influence of pollutant property to the environment is reduced, and the epoxy solvent free paint has characteristics of excellent acid, alkali, oil and chemicals corrosion resistance, construction can be carried out in closed space without hazards such as explosion, suffocation and the like, the primary filming thickness of the invention is 3-4 times of common paint, construction procedures are reduced, and concrete structure and steel structure can be protected from being corroded under carbon dioxide and corrosive conditions.

Description

technical field [0001] The invention relates to coatings, in particular to an epoxy solvent-free coating and a preparation method thereof. Background technique [0002] At present, on the inner walls of various buried pipelines, sewage treatment pools, sewage tanks, cooling towers, wet gas storage cabinets, reservoirs, caverns and tunnels, asphalt-based epoxy coatings are usually used for anti-corrosion and anti-fouling purposes, but asphalt The composition contains heavy metals and other toxic and harmful substances, which are harmful to the environment and the human body. At the same time, epoxy asphalt coatings contain more solvents. In a closed environment on the inner wall, in addition to being harmful to the human body, there is also a danger of explosion; Therefore, a solvent-free, environmentally friendly, asphalt-free, anti-corrosion and anti-fouling performance is currently required in the market, and an anti-fouling coating with better one-time film-forming proper...
