Wood-plastic composite floor and preparation method thereof

Abstract

The invention relates to a wood-plastic composite floor and a manufacturing method thereof. The wood-plastic composite floor manufactured by the method comprises: from top to bottom, a surface coating layer, an upper surface board layer, an upper surface board modified layer, an intermediate layer, The lower panel modified layer and the lower panel layer are compositely composed. It can further alleviate the shortage of precious wood, and the surface of the carbonized surface is modified and then compounded with the intermediate layer, which improves the decoration of the surface of the wood-plastic composite material, and the veneer after carbonization treatment has good dimensional stability, small color difference, and wood. High utilization rate. The 18mm-thick wood-plastic composite floor of the present invention has a bending load of 1240N after being boiled (immersed)-freeze-dried, a dipping peeling rate of 0, and a wet friction coefficient of 0.7; it can save wood resources and have solid wood floors at the same time. Surface effect and other advantages, no harmful substances are released, and can be widely used indoors and outdoors. The manufacturing method is scientific and reasonable and easy to form.

Description

technical field [0001] The invention relates to a floor, in particular to a wood-plastic composite floor and a preparation method thereof. Background technique [0002] With the acceleration of the pace of social life and the improvement of people's living standards, a healthier living environment is required, and wood products are more used in various places, especially as floor covering products - flooring is widely used. But each floor has different advantages and disadvantages. Solid wood flooring has the characteristics of elegance and naturalness, comfortable foot feeling, and good thermal insulation performance, but its dimensional stability is not good enough, and it is easy to arch, warp or deform when the environment is too humid or dry; solid wood composite flooring can better overcome the problems of solid wood flooring. There are indeed disadvantages, but it will inevitably use a large amount of glue in the production process, so there is a problem of releasing...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the existing solid wood composite floor using a large amount of natural precious wood and the release of harmful substances, to provide a floor with stable size, no release of harmful substances, good floor texture and quality, and at the same time taking into account the saving of wood resources and solid wood flooring Surface effects and other advantages, can be widely used in wood-plastic composite flooring indoors and outdoors
