Abstract

The invention discloses a novel ecological non-toxic waterproof flame-retardant bonding agent for straw artificial board production. The bonding agent is prepared from the following ingredients in proportion by weight: 10 to 35 percent of bonding agents, 60 to 90 percent of curing agents, 1 to 5 percent of modifying agents and 3 to 10 percent of phenolic resin. Double ingredients of main bonding agents and the curing agents are used; the certain modifying agents are added so as to enhance the bonding force of the bonding agent and improve the anti-bending intensity and anti-impact and waterproof performance. The bonding agent breaks through the industry barrier that isocyanate is necessary for the production of a straw artificial board at present. The production cost is reduced; the product quality is improved, so that the product has the characteristics of non-toxicity, waterproof performance, flame-retardant performance and the like. All equipment and processes for producing the straw artificial board both at home and abroad adopt a hot pressing process for production, the pollution is great, and the production cost is increased. When the novel special non-toxic waterproof flame-retardant special bonding agent for the straw artificial board is used, a cold pressing process is used for production, and the problem of the complicated hot pressing production process is fundamentally solved; the production efficiency is greatly improved. In addition, the produced product has the advantages of non-toxicity, waterproof performance, flame-retardant performance and an ecological and environment-friendly effect; a new crop straw integral utilization and farmer yield increase path is opened up.

Description

technical field [0001] The invention relates to the field of artificial board manufacturing, in particular to a novel adhesive for straw artificial boards and a production method thereof. Background technique [0002] my country is a large agricultural country with an annual output of 800 million tons of crop straw. In the situation of wood shortage, waste of crop straw resources and strong demand for wood-based panels, using crop straw instead of wood to make wood-based panels is a green and environmentally friendly alternative that saves a lot of forest resources. [0003] As an ecological, environmentally friendly and new energy-saving material, the new environmentally friendly straw-based panel not only has excellent product performance, is non-toxic and harmless, and can reach A-level waterproof and fireproof. Moreover, it can eliminate the pollution of the environment caused by the burning of straw by farmers, and achieve the comprehensive utilization of resources. A...
