Abstract

The invention discloses an environment-friendly wear-resistant thermal-insulation and flame-retardant composite board and a preparation method thereof. The composite board is manufactured from the following raw materials in parts by weight: 7-9 parts an aldehyde-free adhesive, 6-10 parts of reinforcing fiber, 8-10 parts of a fireproof additive, 6-8 parts of a light additive, 4-6 parts of a nano-additive, 40-50 parts of discarded straw, 4-6 parts of dispersible rubber powder, 8-10 parts of filler, 3-5 parts of mesh cloth, 2-4 parts of an organosilicon waterproofing agent and 12-18 parts of a compound aqueous solution. The composite board is better in wear resistance and weather resistance, excellent in compression resistance, tensile strength, dimensional stability and thermal insulation performance, non-toxic, harmless and formaldehyde-free; materials are safe and environmentally friendly, a large amount of agricultural straw is used, so that the cost is reduced, resources are saved, continuous production is realized, production efficiency is greatly improved, the process is simple and concise, and the composite board has higher practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of environmental-friendly plates, in particular to an environmentally-friendly, wear-resistant, heat-retaining, and flame-retardant composite plate and a preparation method thereof. Background technique [0002] On the one hand, since most of the existing wood-based panels emit more or less harmful gases and formaldehyde that is harmful to the human body and the living environment, in order to meet the standard requirements, manufacturers use modified urea-formaldehyde resin adhesives for production , so that the release of formaldehyde from the blockboard is greatly reduced, but this measure cannot completely eliminate the release of formaldehyde. In the case of a large amount of use, the pollution of the indoor environment by the released formaldehyde is still relatively serious. [0003] On the other hand, the development trend of wood-based panels is rapidly changing from wood to various wood substitutes...
