Problems solved by technology

Because the solid content of water-based paint is not high, water-based paint needs drying equipment to dry and remove water before curing into a film, otherwise it will affect the performance of the paint film after film formation, which will lead to increased energy consumption, longer production time, and higher production costs.
It is necessary to solve the problems of low hardness and poor wear resistance of the paint film when it is applied to the resin film floor

Abstract

The invention provides a water-based paint resin film veneer solid wood composite floor with low VOCs release and a preparation method thereof. The water-based paint resin film veneer solid wood composite floor sequentially comprises a water-based paint surface layer, a resin film decorative layer, a plurality of base material layers and a back plate from top to bottom. The preparation method mainly comprises the following steps: preparing water-based UV finish paint; preparing a resin film decorative layer; and preparing the water-based paint resin film veneer solid wood composite floor withlow VOCs release.

Description

technical field [0001] The invention relates to the technical field of production and processing of solid wood composite flooring, in particular to a water-based paint resin film-finished solid wood composite floor with low VOCs release and a preparation method thereof. Background technique [0002] Wood flooring is a commonly used ground decoration material. The main varieties include laminate flooring, solid wood composite flooring, solid wood flooring, and impregnated paper laminate veneer multi-layer solid wood composite flooring. With the implementation of the national real estate full decoration delivery policy, the sales volume of solid wood composite flooring is always on the rise. However, due to the use of precious broad-leaved tree species on its surface, it faces many bottlenecks in sustainable development. For example: (1) the world's major All timber supplying countries have introduced corresponding forest protection laws and regulations, resulting in tighter s...
