High-strength lightweight environment-friendly composite board and preparation method thereof

Abstract

The invention discloses a high-strength lightweight environment-friendly composite board and a preparation method thereof. The high-strength lightweight environment-friendly composite board is prepared from the following raw materials in parts by weight: 30-40 parts of polyamide fiber, 6-8 parts of dispersible emulsion powder, 6-8 parts of capsular perlite, 30-40 parts of plant fiber, 5-7 parts ofantibacterial mothproof additive, 18-24 parts of inorganic phosphate adhesive, 2-4 parts of waterproof agent, 1-3 parts of silicon oxide, 10-16 parts of adhesive auxiliary, 10-12 parts of flame retardant additive, and 3-5 parts of zinc stearate. The high-strength lightweight environment-friendly composite board disclosed by the invention is light in weight, high in strength, waterproof and wearable, and has good antibacterial mothproof performance; the material is free from formaldehyde and peculiar smell, and is environmentally friendly; furthermore, the preparation method disclosed by the invention is low in cost, easy to obtain raw materials, concise in process, has higher practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of composite board materials, in particular to a high-strength, light-weight and environmentally friendly composite board and a preparation method thereof. Background technique [0002] Existing indoor insulation materials mostly use benzene board, but its disadvantages are that it will release harmful gas, not resistant to aging, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, difficult construction, high engineering cost, and other Resources are limited and difficult to recycle. From the point of view of environmental protection, cork insulation effect is good, but the cost is too high. [0003] At the same time, most of the existing wood-based panels in the market are products with adhesives applied, and the adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and amm...

AI Technical Summary

Problems solved by technology

[0002] Existing indoor insulation materials mostly use benzene board, but its disadvantages are that it will release harmful gas, not resistant to aging, large deformation coefficient, poor stability, poor safety, easy to burn, poor ecological environmental protection, difficult construction, high engineering cost, and other Resources are limited and difficult to recycle

From the point of view of environmental protection, cork insulation effect is good, but the cost is too high

[0003] At the same time, most of the existing wood-based panels in the market are products with adhesives applied, and the adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and ammonia into the environment, seriously polluting the environment and affecting people's health

At present, the environment-friendly wood-based panels developed and used in the industry usually adopt the method of adding negative ion coating to suppress the release of toxic gases in the wood-based panels. Gas defects, and the limitations of the existence time, contact area, and validity period of toxic gases fixed by negative ions cannot fundamentally solve the above-mentioned problem of wood-based panels polluting the environment

In addition, the existing wood-based panels have single functions, poor durability and durability, and short service life

[0004] In addition, with the passage of time, it is easy to breed insects and centipedes in the artificial board, which is very unsanitary, and it will crawl into the house of the residents, causing certain troubles
