Abstract

The invention discloses a high-performance artificial board. The high-performance artificial board comprises, by weight, 84-96 parts of cypress saw milling powder, 17-23 parts of corn straw powder, 6-8 parts of carbon calcium powder, 3-8 parts of polyester resin, 0.9-1.6 parts of an initiator a, 0.8-1.5 parts of a curing agent, 0.7-1.3 parts of a waterproof agent, 1-1.8 parts of flame retardant, 1.2-2 parts of a smoke inhibitor, 0.2-0.6 part of an accelerator and 12-24 parts of adhesive. The adhesive is high in bonding strength and water resistance and completely meets the related standards in GB / T14732-2006; the strength of the produced artificial board far exceeds the standards of second-class national artificial boards, the adhesive can be widely applied to production of artificial boards, plywood and cellulose boards on an industrial production line, and is used by replacing urea formaldehyde adhesive, phenolic aldehyde adhesive and methyl aldehyde adhesive, and dependency on fossil resources is reduced; the high-performance artificial board is high in mechanical strength and easy to form in an adhesive-dipping mode.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of artificial board preparation, and in particular relates to a high-performance artificial board and a preparation method thereof. [0003] 【Background technique】 [0004] my country is a large agricultural country, with an annual output of about 800 million tons of crop straw. The traditional way to deal with these large amounts of crop straw is to burn it on the spot or pile it up to make it rot, which has caused serious environmental pollution and other problems. [0005] At present, my country has made great breakthroughs in the use of crop straws to process man-made panels. However, due to the low lignin content of the existing simple crop straw wood-based panels, the medium density boards produced therefrom have low mechanical strength and small nail-holding force. The pure crop straw wood-based panel is not easy to be glued and formed due to the high wax content in the crop straw. [0006] ...
