Problems solved by technology

The existing bamboo board preparation process is mostly prepared by cutting, crushing, mixing, curing, pressing, and curing, and can obtain relatively high-quality environmentally friendly bamboo boards, but its strength is not ideal, and the insect-proof and moisture-proof performance is also in some special cases. The humid area is not ideal, and it is obvious that it cannot be exposed to fire, which greatly limits its application and popularization

Abstract

A preparation method of high-strength fireproof corrosion-resistant type bamboo boards comprises the following steps that selected bamboo wood is cut primarily, and bamboo joints are removed; perpendicular sectioning is conducted, so that thin type long-strip-shaped bamboo wood is formed; the thin type long-strip-shaped bamboo wood is steamed for 0.5-1 h at the high temperature of 100-120 DEG C; the thin type long-strip-shaped bamboo wood is placed on a hollowed-out rack to be dried, blown and irradiated with ultraviolet rays; the thin type long-strip-shaped bamboo wood is smashed into bamboo powder; materials are mixed, wherein 70-90 parts of the bamboo powder, 5-10 parts of silica powder, 3-8 parts of mica powder, 4-6 parts of starch, 20-30 parts of water and 15-25 parts of PVC powder are fetched and stirred to be evenly mixed; then, 15-30 parts of bonding adhesive is added and stirred to be evenly mixed with the mixture; aging is conducted; pressing and solidifying are conducted; and the surfaces of obtained products are coated with a nanometer-scale fireproof coating material. The bamboo wood is pretreated through preceding processes, so that the moisture and sugar in the bamboo wood are greatly reduced; besides, ultraviolet irradiation is also conducted, and formula auxiliary materials are added during material mixing; and in this way, the strength, the fire resistance, the inspect preventing performance and the corrosion resistance of the final bamboo boards are improved, and the application range of the bamboo boards is widened.

Description

technical field [0001] The invention relates to a bamboo board technology, in particular to a method for preparing a high-strength fire-resistant and anti-corrosion bamboo board. Background technique [0002] In the building materials industry, particle board is widely used as a kind of particle board, occupying a place in the market with its low cost and mature technology, and becoming the choice of most furniture design and decoration design. However, the environmental protection performance and durability of this kind of board are all unsatisfactory. Bamboo board has excellent physical properties, and has the advantages of small coefficient of water absorption, no cracking, no deformation, etc., and it is currently emerging rapidly. The existing bamboo board preparation process is mostly prepared by cutting, crushing, mixing, curing, pressing, and curing, and can obtain relatively high-quality environmentally friendly bamboo boards, but its strength is not ideal, and the...
