Abstract

The invention aims to provide a biomass flame-retardant thermal-insulating panel and a preparing method thereof. By the biomass flame-retardant thermal-insulating panel, the environmental-friendly straw panel which integrates high strength and flame retardation and is low in energy consumption is produced. The biomass flame-retardant thermal-insulating panel consists of biomass raw materials and an adhesive in a mass ration of 1:0.3- 1. The biomass raw materials comprise crop straw, shells, core wood and carbides; the adhesive is prepared from silica sol or sodium silicate, aluminium chloride, filler, curing agent and stabilizer; the filler is a composite consisting of aluminium oxide, zinc oxide and magnesium oxide; the curing agent is one of aluminium hydroxide, magnesium hydrate or zinc hydroxide; and the stabilizer is carboxymethylcellulose sodium.The preparing method comprises the following steps of: the pretreatment of biomass raw materials; dosing; and hot press molding. The biomass flame-retardant thermal-insulating panel is abundant in raw materials, and the preparing is simple, energy-saving and environment-friendly. The product has the advantages of flame retardance, water prevention, insect prevention, high mechanical property and heat-insulating property, low cost and the like, and has the huge economic and social benefits.

Description

technical field [0001] The invention relates to a board, in particular to a biomass flame-retardant and heat-insulating board and a preparation method thereof. Background technique [0002] my country is a large agricultural country with abundant straw resources. Rice straw, wheat straw and corn straw are the three major crop straws. According to estimates by experts, the annual output of crop straws in my country is 726 million tons, accounting for about 30% of the total straw in the world. Currently, the effective utilization rate of crop straws is only 33%. Doing a good job in the comprehensive processing and utilization of crop straws can not only reduce the environmental pollution caused by straw burning, but also is a major strategic issue for the practice of developing circular economy. [0003] my country is a big country in the production and consumption of wood-based panels, and the annual output of wood-based panels has exceeded 100 million m 3 , more than 200 m...
