Problems solved by technology

[0009] Although the above-mentioned coatings are all environmentally friendly coatings, they still cannot guarantee that they will be completely free of volatile harmful substances. Therefore, it is necessary to study a ground coating that can achieve zero harmful volatile substances to meet the needs of consumers.

Abstract

The invention discloses an environment-friendly epoxy resin coating, an environment-friendly coiled material and a preparation method thereof. The coating comprises a component A and a component B in a weight ratio of 10 to (3-6), wherein the component A comprises 35-60 parts by mass of bisphenol F epoxy resin, 10-25% by mass of cycloaliphatic epoxy resin, 1-5% by mass of toughening agents, 0.5-1% by mass of coupling agents, 0.1-0.5% by mass of defoaming agents, 0.1-0.5% by mass of levelling agents, 1-5% by mass of colour paste and the balance of environment-friendly fillers; the component B comprises 89-96% by mass of curing agents, 1-5% by mass of epoxy resins and the balance of curing accelerators. The coating has the beneficial effects that as the bisphenol F epoxy resin, the cycloaliphatic epoxy resin and the environment-friendly fillers are adopted as the components of the coating, not only are volatile harmful substances not introduced to the fillers of the coating but also the following characteristics of the coating are ensured: low density, wear resistance, water resistance, flexibility and comfort.

Description

Technical field [0001] The invention relates to the technical field of polymer coatings, in particular to an environment-friendly epoxy resin paint, an environment-friendly coil and a preparation method thereof. Background technique [0002] With the improvement of living standards, the continuous increase of labor wages, and the strengthening of environmental protection awareness, people's choice of coils has gradually changed to environmental protection, simplification, and harmlessness. [0003] At present, the more common household and commercial space decoration coils are mainly divided into two types of coils: block and coil. [0004] Among them, block materials mainly include ceramic tiles, laminate flooring, solid wood flooring, etc. The radioactive substances of ceramic tiles have attracted more and more attention. Laminate flooring contains melamine and formaldehyde, solid wood flooring is more expensive, and the paving of such block materials is more troublesome. It requi...
