Rice-wheat haulm plywood and process technique thereof

Abstract

Disclosed are a composites plate of rice and wheat straw and the process thereof, which belong to the technical field of processing of constructional or decorative planks. The invention is characterized in that the composites plate is processed by the materials according to weight percentage of rice straw powder, wheat straw powder or mixed powder of rice and wheat powder 40-60%, light magnesium-oxide 10-30% and epoxy adhesive 30-40%. The process comprises the steps that preparing rice straw powder, wheat straw powder or mixed powder of rice and wheat powder according to the weight percentage and placing the powder in a container, then adding the light magnesium-oxide in the rice straw powder, wheat straw powder or mixed powder of rice and wheat powder according to the weight percentage, then mixing the mixture homogeneously under constant temperature, then adding the epoxy adhesive according to the weight percentage, stirring the mixture continuously homogeneously under constant temperature, pouring the stirred mixture in a prefabricated mould, and finally required plate finished products are accomplished after pushing process. The invention has easily accessible materials, solves the problem of further processing, which is high in strength, firm and durable.

Description

Technical field:

[0001] The invention relates to a rice-wheat straw plywood and its processing technology, which belongs to the technical field of plate processing for building or decoration. In particular, a technology that can replace wood plywood or compressed board, using rice straw and straw to make plywood. Background technique:

[0002] Existing plywood is usually pressed with sawdust or bonded with wood. For example, in Chinese Patent No. 01142809.0, "A kind of high-quality solid wood three-layer plywood processing wood floor and construction method" is described. A panel with a sawing mold is provided on the sawing surface of an electric disc saw or an electric blade cutting saw, and two sets of parallel grooves are arranged on the width direction of the panel, arranged on both sides of the front center line of the saw kerf. The two groups of parallel grooves are provided with a slidable limit frame, and a single-head bolt is arranged in the limit frame, and the b...
