Problems solved by technology

Reactive diluents are generally added to solvent-free epoxy coatings to reduce the viscosity and facilitate construction, but it will lead to a decrease in cross-linking density and reduce the performance of the coating.
Without adding active diluent, the viscosity of the paint is very high, so it can only be applied by double-tube feeding heating and airless spraying

Abstract

The invention belongs to the field of epoxy coating, and particularly relates to a loadable solvent-free epoxy resin floor coating. The coating is prepared from a component A and a component B; the component A is prepared from, by weight, 90-100 parts of bisphenol A epoxy resin, 40-45 parts of quartz sand and 10-15 parts of tea stem powder; the component B is prepared from, by weight, 10-15 parts of modified polyamide and 0.2-2.0 parts of trimethyl hexamethylene diamine; the mass ratio of the component A to the component B is 5:1. The coating is environmentally friendly, high in hardness, good in wear resistance, applicable heavy-load places, good in chemical resistance, high in adhesive force, excellent in durability and corrosion resistance, resistant to scratches, short in drying time and easy and convenient to construct.

Description

technical field [0001] The invention belongs to the field of preparation of epoxy coatings, and in particular relates to a load-carrying solvent-free epoxy resin floor coating. Background technique [0002] Epoxy resin coatings have the advantages of strong anti-corrosion ability, strong adhesion, high hardness, wear resistance, salt spray resistance, acid and alkali resistance, high gloss, high solid content, and high fullness. Therefore, it is widely used as industrial heavy-duty anti-corrosion paint, anti-rust primer, floor paint, oil tank paint, drinking water tank paint, etc. However, traditional solvent-based coatings contain more than 30% organic solvents. During the process of manufacturing, construction, drying, and curing of coatings, a large amount of VOC is released into the atmosphere, which constitutes extremely serious pollution and harm to the human ecological environment. threaten. The solvent-free epoxy coating has no volatile organic solvents, is non-tox...
