Problems solved by technology

[0003] Chemical pollution and toxic damage, solvent-based coating products themselves have certain chemical hazards
In the work of Xu clothing, it is necessary to pay attention to the air pollution caused by solvents and thinners in the paint, which is harmful to the human body; fire and explosion hazards, solvent-based paints, and thinners used in painting operations are mostly flammable and explosive. Materials, so the painting operation itself has the hidden danger of fire and explosion
The possible causes of fire and explosion are that the operation rules are not followed during electrostatic painting, and discharge sparks are easily generated; waste paint, paint mist, paint materials and solvent waste rags are not well kept, and they are easy to spontaneously ignite and ignite when they are piled up; electrical equipment Improper selection or use, or failure to repair in time after damage, insufficient explosion-proof level, etc.; lightning strike disasters during thunderstorm season

Abstract

The invention discloses a room-temperature self-setting corrosion protective coating. The room-temperature self-setting corrosion protective coating is prepared from the following main components in parts by weight: 30-75 parts of polyurethane, 15-18 parts of polytetrafluoroethylene, 12-15 parts of zinc phosphate, 12-16 parts of n-butanol, 5-8 parts of strontium sulfate, 3-8 parts of sodium hexametaphosphate, 5-7 parts of a dispersant, 1-3 parts of a toughening agent, 2-5 parts of a flatting agent and 3-6 parts of a plasticizer. The invention also discloses a room-temperature self-setting corrosion protective coating and a preparation method thereof. The room-temperature self-setting corrosion protective coating can be used under the rigour condition, is long in the corrosion protective life and also has excellent characteristics of weatherability, ageing, radiation, abrasion, impact, high temperature and low temperature resistance and stability in electrical conductivity. With the adoption of the room-temperature self-setting corrosion protective coating, the resistivity can meet the requirement for electrostatic resistance, and long service life of the coating can also be ensured.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to an anti-corrosion coating, in particular to a normal-temperature self-curing anti-corrosion coating and a preparation method thereof. Background technique [0002] Anti-corrosion coatings have become an important new force in the field of coatings. Anti-corrosion coatings are playing an increasingly important role, and their development prospects are promising.
