Weatherproof flexible veneer and manufacturing method thereof

Abstract

The invention provides a weatherproof flexible veneer, which comprises a nonwoven fabric layer, a polyurethane (PUR) hot melt adhesive layer, a wood solid veneer layer, a water-based coloring layer, a PUR hot melt adhesive paint layer and an ultraviolet (UV) finish paint layer, wherein the nonwoven fabric layer is bonded with the solid wood veneer layer through the PUR hot melt adhesive layer, and the water-based coloring layer, the PUR hot melt adhesive paint layer and the UV-side paint layer are sequentially coated on the upper surface of the solid wood veneer layer. The weatherproof flexible veneer has good flexibility and does not crack and prevents the paint from peeling off after being bent for multiple times, the adopted synthesized materials can meet the international environment-friendly requirement, a traditional paint technical is changed, no pollution is led to an application environment, the utilization rate of the paint is high, the weatherproof flexible veneer is free from being delaminated at a high temperature and being embrittled at a low temperature, has excellent properties such as ultraviolet resistance, aging resistance and water resistance and can be made into a veneer synthesized material which can be continuously coiled, and the requirement on elongation and mass production of the material can be met.

Description

technical field [0001] The invention belongs to the field of wood processing, in particular to a weather-resistant flexible veneer. Background technique [0002] Wood veneer is one of the essential materials in the building materials and furniture industry. Ordinary wood veneer is not flexible enough, it is easy to crack when bent, the paint is easy to fall off, it is easy to delaminate at high temperature, and it is easy to be brittle at low temperature. It is anti-ultraviolet, anti-aging, waterproof, etc. The performance is poor, and the traditional paint process pollutes the environment, and the paint utilization rate is not high. [0003] Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a weather-resistant flexible veneer. [0005] A weather-resistant flexible veneer is characterized in that it includes a non-woven fabric layer, a PUR hot-melt adhesive layer, a solid wood cortex layer, a water-based col...
