Abstract

The invention discloses a preparation method of mould-proof bamboo plywood with high bonding strength. The preparation method comprises steps as follows: bamboo curtains are ultrasonically treated and then dried; the dried bamboo curtains are subjected to plasma treatment; the bamboo curtains subjected to plasma treatment are dipped in glue adopting a modified epoxide resin adhesive; after glue dipping, the bamboo curtains are dehumidified and then assembled to form a blank; hot-pressing solidification is performed. The modified epoxide resin adhesive comprises components in parts by weight as follows: 50-60 parts of epoxy resin, 30-40 parts of phenolic resin, 15-20 parts of polyurethane resin, 2-5 parts of silicon resin methyl branched silicon oil, 1-3 parts of dipentaerythritol, 3-6 parts of polyborosiloxane, 15-18 parts of sepiolite, 5-8 parts of nano magnesia, 7-10 parts of corn starch, 0.4-1 part of an anti-ageing agent and 2-3 parts of butyl p-hydroxybenzoate. By means of the preparation method of the mould-proof bamboo plywood with the high bonding strength, the bonding strength of the obtained bamboo plywood is high, the water absorption expansion rate is low, and the corrosion resistance is excellent.

Description

technical field [0001] The invention relates to the technical field of bamboo plywood, in particular to a method for preparing a mold-proof bamboo plywood with high gluing performance. Background technique [0002] Bamboo plywood is a board made of moso bamboo as the main structure and filling material, which is formed into a billet under high pressure and cured at high temperature. Bamboo plywood has the characteristics of high hardness, flexural resistance, strong pressure resistance, good wear resistance, and low water expansion rate. Its main uses are: building formwork, bamboo plywood pallets for concrete block (brick) production, and automobile trunk boxes Board and box bottom, train car box and bottom, container board, refrigerated ship board, decorative bamboo floor and other related boards. And because bamboo is easy to cultivate, it can be felled in more than four years, and it will grow quickly. Therefore, the use of bamboo to replace wood is the direction of nat...
