Problems solved by technology

At the same time, the veneer absorbs moisture and swells, loses water and shrinks, and its performance is quite different from that of stone plastic, which may easily cause the veneer surface to warp
In addition, due to the poor waterproof performance of natural veneer, it is not suitable for outdoor use, and its application after bonding with stone-plastic substrates is greatly limited.

Embodiment 1

[0076] This embodiment is a modified veneer, the preparation method of which includes the following steps: soak the veneer with a thickness of 0.6 mm in a treatment solution with a methyl methacrylate concentration of 98%, and the treatment solution contains a mass concentration of 2% ethanol penetrating agent; transferred to pressurized tank after full soaking, at 1.2kg / m 2 Keep the pressure for 60 minutes in an inert atmosphere under 100°C, then carry out polymerization reaction in a reaction tank at 100°C, and then carry out equilibrium treatment at 25°C and an environment with a relative humidity of 25% for 7 days to complete the modification of veneer.

Embodiment 2

[0078] This embodiment is a modified veneer, the preparation method of which includes the following steps: soak the veneer with a thickness of 0.8 mm in a treatment solution with a methyl methacrylate concentration of 97%, and the treatment solution contains a mass concentration of 3% ethanol penetrating agent; transferred to pressurized tank after full soaking, at 1.3kg / m 2 Keep the pressure for 50 minutes in an inert atmosphere at 100°C, then carry out the polymerization reaction in a reaction tank at 100°C; then perform an equilibrium treatment at 22°C and a relative humidity of 40% for 6 days to complete the modification of the veneer.

Embodiment 3

[0080] The present embodiment is a modified veneer, the preparation method of which comprises the following steps: soak the veneer with a thickness of 1.0 mm in a treatment solution with a methyl methacrylate concentration of 98%, and the treatment solution contains a mass concentration of 2% ethanol penetrating agent; transferred to pressurized tank after full soaking, at 1.3kg / m 2 Keep the pressure for 70 minutes in an inert atmosphere at 100°C, then carry out the polymerization reaction in a reaction tank at 100°C; then perform an equilibrium treatment at 28°C and a relative humidity of 35% for 8 days to complete the modification of the veneer.

Abstract

The invention provides a modified wood veneer, a modification method of the wood veneer, a wood veneer / stone plastic composite plate and a preparation method of the wood veneer / stone plastic compositeplate, and relates to the technical field of plates. The modified wood veneer comprises a wood veneer base material and polymethyl methacrylate which coats the surface of the wood veneer base material and / or permeates into the wood veneer base material. By utilizing the modified wood veneer, the technical problem that a wood veneer in the prior art is prone to moisture absorption and deformationcan be relieved, and the technical effect of improving the stability of the wood veneer can be achieved.

Description

technical field [0001] The invention relates to the field of plates, in particular to a modified veneer, a modification method of veneer, a veneer / stone-plastic composite plate and a preparation method thereof. Background technique [0002] Stone plastic board, also known as PVC sheet board, is a new type of floor and wall decoration material. It mainly uses natural marble powder to form a solid base layer with high density and high fiber mesh structure. Made of molecular PVC wear-resistant layer. Compared with other floor and wall decoration materials, stone-plastic floor has obvious advantages. For example, the main raw material of stone-plastic board is natural stone powder, which does not contain radioactive elements, and can be completely recycled and reused, which is more environmentally friendly; Light and thin, it has great advantages in building load-bearing and space saving in high-rise buildings; in addition, stone-plastic panels have super wear resistance, high ...
