Problems solved by technology

[0002] Our country is a large agricultural country, and the residual amount of crop straw subsidiary products is as high as more than 1 billion tons every year. This is a huge renewable resource. Manufacturing wood-based panels with straw is the most marketable development potential and industry for industrial utilization of straw. It is one of the best ways to solve the comprehensive utilization of crop straws, but compared with wooden boards and wood-based panels, its straw-based panels still have certain shortcomings in their physical strength properties. The impact strength is still not up to the level of wooden panels and wood-based panels, and some physical problems have not yet been satisfactorily resolved.

Abstract

A composite straw (or stalk)-plastics board is composed of a core board made of the straw or stalk of agricultural crops and with two adhesive layers on its both surface, and two veneers adhered respectively onto said two adhesive layers. Said veneer is chosen from high-density plywood, polyhydroamine solution immersed paperboard, and PCC plate. Said adhesive is chosen from MVF adhesive, high-adhesion emulsion adhesive and universal adhesive.

Description

Technical field [0001] The invention relates to an artificial composite board, in particular to a crop straw wood-plastic composite board. Background technique [0002] Our country is a large agricultural country, and the residual amount of crop straw subsidiary products is as high as more than 1 billion tons every year. This is a huge renewable resource. Manufacturing wood-based panels with straw is the most marketable development potential and industry for industrial utilization of straw. It is one of the best ways to solve the comprehensive utilization of crop straws, but compared with wooden boards and wood-based panels, its straw-based panels still have certain shortcomings in their physical strength properties. The impact strength has not yet reached the level of wooden panels and wood-based panels, and some physical problems have not been satisfactorily resolved so far. Contents of the invention [0003] In order to solve the problems of the physical strength of st...
