Manufacturing process for woven wheat straw board

Abstract

The invention discloses a manufacturing process for a woven wheat straw board. The manufacturing process for the woven wheat straw board comprises the following steps: (1) splitting wheat straws in to wheat straw sheets; (2) drying the wheat straw sheets; (3) adding isocyanate adhesive into the dried wheat straw sheets and stirring uniformly; (4) weaving and paving the wheat straw sheets into board blanks in a crisscrossed mode; and (5) performing hot press molding on the board blanks to form the woven wheat straw boards with clear and natural surface texture. By the adoption of the technical scheme, the wheat straws are split into the wheat straw sheets, and the wheat straw sheets are woven and paved in the crisscrossed mode. The wheat straws are not crushed and hot press molding is adopted, so that the strength and the toughness of the formed wheat straw board can be improved completely, and the surface texture, the inner woven structure, the physical property and the like of the wheat straw board are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of man-made composite boards, in particular to a manufacturing process of woven wheat straw boards. Background technique [0002] Wheat straw board is a man-made composite board with excellent performance made of agricultural production residue - wheat straw. Wheat straw board is between medium density fiberboard and wood particleboard in terms of performance. It is a homogeneous board like medium density board and has a very smooth surface. Its production cost is lower than that of particleboard. It is stable in strength and size. It is superior to wood particleboard in terms of durability, machinability, screw and nail holding ability, waterproof performance, veneer performance and density (20% lighter). It does not release formaldehyde, so it does not pollute the environment. It does not rely on the increasingly scarce wood raw material, but uses cheap and inexhaustible wheat straw that can be renewed e...

AI Technical Summary

Problems solved by technology

However, the production of wheat straw boards is not common in China at present. The wheat straw boards produced by the existing production technology are produced after crushing wheat straw, and they are not as good as wood-based boards in terms of waterproof performance, section density, mechanical properties, and appearance. Quality requirements, it is difficult to popularize and recognize in the market
