example 1

[0018] First, weigh 10g of red thistle leaves, wash them with deionized water for 3 times, and pulverize the washed red thistle leaves with a pulverizer to obtain powder of red thistle leaves, put the powder in a beaker, and add 300mL to the beaker. Ionized water, and placed in a 180W ultrasonic oscillator for 20 minutes, filtered to obtain the filtrate, which is the extract of red thistle leaves, for subsequent use; then weigh 10g of Artemisia annua, wash 3 times with deionized water, and wash the cleaned artemisia Put artemisia in a beaker, add 300mL of n-hexane into the beaker, transfer the beaker to a microwave extractor, extract at 30°C and 20MPa for 1 hour, filter to obtain a filtrate, and distill the filtrate under reduced pressure to obtain a solid, which is Artemisia annua extract, for subsequent use; then take 400g bamboo slices, cut the bamboo slices into 5cm in length, dry the cut bamboo slices in a 95°C oven until the moisture content of the bamboo slices is 10%, a...

Abstract

The invention discloses a preparation method for anti-corrosion flame-retardant bamboo plywood and belongs to the technical field of bamboo plywood preparation. The preparation method comprises the steps that a prepared ageratum conyzoides leaf extracting solution and a prepared artemisia princeps extract are added with deionized water, stirred and mixed, added with processed bamboo pieces and dried after being soaked, and bamboo pieces containing germicidal components are obtained and soaked in prepared flame-retardant gum; after gum soaking is conducted, the bamboo pieces are put into a drying oven to be dried; and then the dried bamboo pieces are subjected to blank assembling, curing and hot pressing, so that the anti-corrosion flame-retardant bamboo plywood is obtained. Examples prove that the operation process of the preparation method is simple and convenient, the ordinary bamboo piece materials are adopted, resources are rich, and the production cost is reduced; in addition, the prepared bamboo plywood is good in adhesion property and low in water absorption expansion rate, and the flame retardance and the corrosion resistance are also significantly improved; and after the anti-corrosion flame-retardant bamboo plywood is used, warping and degumming are not prone to occurring, so that the market prospects are broad.

Description

technical field [0001] The invention discloses a method for preparing an anti-corrosion and flame-retardant bamboo plywood, which belongs to the technical field of bamboo plywood preparation. 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, replacing wood with bamboo is a guide that is supp...
