Abstract

The invention discloses a preparation method for high-strength antibacterial mould-proof bamboo plywood. The preparation method comprises the steps that a bamboo sheet is manufactured, specifically, the bamboo sheet is dried to be 8-15% in moisture content, and then the bamboo sheet is subjected to plasma processing to obtain a material A; the material A is added into an antibacterial agent to be soaked for 30-45 min, and then is dried to be 8-15% in moisture content to obtain a material B; the material B is soaked in a phenolic resin adhesive for 100s-120s, and then is dried to be 10-15% in moisture content to obtain a material C; the material C is assembled to obtain a work board; the work board is subjected to hot-pressing consolidation to obtain a substrate; and the substrate is aged to obtain the high-strength antibacterial mould-proof bamboo plywood. The preparation method for the high-strength antibacterial mould-proof bamboo plywood has the advantages of being simple in process, mild in condition and low in cost; and the obtain bamboo plywood is high in strength, good in corrosion resistance and excellent in antibacterial and mould-proof performance.

Description

technical field [0001] The invention relates to the technical field of bamboo plywood, in particular to a preparation method of high-strength antibacterial and mildew-resistant bamboo plywood. Background technique [0002] China is rich in bamboo resources. Today, when timber resources are in short supply, bamboo plywood has a bright prospect as a new material for replacing wood with bamboo. In the manufacturing process of bamboo products, bamboo gluing is one of the key processes in the production process of bamboo products. In the process of bamboo gluing, phenolic resin adhesive is a commonly used adhesive. However, the bonding process is a complex physical, chemical or both process. The quality of bonding depends not only on the structure and state of the adhesive and the surface of the material to be bonded, but also on various process conditions in the bonding process. closely related. Existing bamboo plywood has defects such as low strength, poor antibacterial and a...
