Abstract

The invention discloses a preparation method of bamboo plywood with high bonding strength. The preparation method comprises the following steps of (S1) performing ultrasonic treatment on a bamboo curtain; (S2) carbonizing the bamboo curtain after ultrasonic treatment, specifically, the carbonization treatment comprises the steps of sending the bamboo curtain into a drying and disinfecting carbon dryer, the heating temperature of the drying and disinfecting carbon dryer is 160 to 190 DEG C, the heating time is 2 to 4 hours, and the bamboo curtain is carbonized till the carbonizing degree is 5%to 30%; (S3) performing plasma treatment on the bamboo curtain after carbonization; (S4) gumming the bamboo curtain after plasma treatment, specifically, a modified phenolic resin adhesive is adoptedduring gumming; (S5) dehumidifying the bamboo curtain after gumming; (S6) assembling the bamboo curtain after dehumidification; and (S7) hot-pressing and solidifying.

Description

technical field [0001] The invention relates to the technical field of bamboo plywood, in particular to a preparation method of high bonding strength bamboo plywood. 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 national policy suppor...
