Flame-retardant waterproof phase-change energy storage formaldehyde-free solid wood composite board and manufacturing method thereof

Abstract

The invention relates to a flame-retardant, waterproof, phase-change energy-storage formaldehyde-free solid wood composite board and a production method thereof, which solve the problem of excess formaldehyde in the adhesive used in the production of existing composite boards, and have functions of flame-retardant, waterproof, and phase-change energy storage. The solid wood layer and the flame-retardant and waterproof phase-change energy storage layer laminated on the solid wood layer by pressure, the flame-retardant and waterproof phase-change energy storage layer is composed of expanded perlite, Glauber's salt, calcium chloride hexahydrate, n-octylic acid and butyl stearate Any phase change material in grease, silica sol solution, plant fiber, calcium carbonate, penetrating agent, flame retardant, waterproofing agent, color material, mix the ingredients evenly and spread the material, and lay non-woven fabric on the material , after being rolled by a rolling machine, it becomes a flame-retardant layer plate, and the surface of the flame-retardant and waterproof phase-change energy storage layer is coated with a formaldehyde-free water-based adhesive, and the solid wood layer plate is placed on the pre-pressing machine, and the solid wood layer and flame-retardant The waterproof phase-change energy storage layer is superimposed and pre-compressed so that the solid wood layer is close to the flame-retardant waterproof phase-change energy storage layer, and the hot press is pushed for hot pressing to become a solid wood composite board, which solves the problem of excessive formaldehyde in the adhesive in the production of existing composite boards Problems and has the advantages of energy saving, fire prevention, waterproof.

Description

technical field [0001] The invention relates to a flame-retardant, waterproof, phase-change energy-storage formaldehyde-free solid wood composite board and a manufacturing method thereof, which can solve the problem of excessive formaldehyde in adhesives in the production of existing composite boards and have flame-retardant, waterproof, and phase-change energy storage functions. Background technique [0002] At present, there are several types of flame-retardant boards on the market, with various varieties and different performance and quality. There are mainly flame-retardant wood-based panels and glass magnesium boards. Wood-based panels are made of urea glue or phenolic glue, the formaldehyde exceeds the standard, not waterproof, and easy to crack. Although the formaldehyde content of the board made of modified urea glue is low, it is neither fireproof nor waterproof; glass magnesium board is only fireproof, not waterproof. It is waterproof, and a large amount of glass w...
