Problems solved by technology

[0007] The purpose of the present invention is to provide a non-woven fabric reinforced laminated veneer lumber manufacturing method for the poor physical and mechanical properties of the existing decorative profile laminated veneer lumber and the easy cracking of the surface coating. The manufactured non-woven reinforced laminated veneer lumber has excellent physical and mechanical properties, and is especially suitable for use as a base material for decorative profiles. The mechanical properties are superior to the indicators of all-wood laminated veneer lumber, and the successful implementation of non-woven fabric-reinforced laminated veneer lumber has significant economic and social benefits

Abstract

The invention discloses a production method for non-woven fabric enhanced laminated veneer lumber used as decorative profile base materials. Veneer and non-fabric which are served as raw materials are assembled to be in a required thickness after processing and are hot pressed to form into laminated veneer lumber through a hot compressor. The laminated veneer lumber base materials produced through the production method has the advantages of being good in physical and mechanical performance, reducing production costs, improving product technological contents and additional values, enabling existing timber resources and small and medium fast growing wood veneer to be effectively used, meanwhile improving the production efficiency, enabling the environmental protection standard to achieve a E1-level requirement, being capable of exporting to Europe and Southeast Asia countries and having remarkable economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a method for manufacturing a non-woven reinforced veneer laminate used as a base material of a decorative profile. Background technique [0002] With the rapid development of my country's economy, the contradiction between supply and demand of timber has become increasingly prominent, and the resources of Dajing grade and hard broad-leaved timber are relatively scarce. Coupled with the relatively backward production equipment and technology of other types of wood-based panels, the comprehensive utilization rate of wood is low, and wood waste is serious, which to a certain extent restricts the development of the wood-based panel industry. How to make efficient use of existing wood resources and improve the technological content and added value of products is an urgent problem to be solved. Decorative wood, including wooden decorative profiles, has become m...
