Method for manufacturing environment-friendly waterproof fiber board

Abstract

The invention discloses a method for manufacturing an environment-friendly waterproof fiber board. The method is technologically characterized in that prehydrolysis treatment is not conducted on raw materials, and hydrolysis and hot pressing of the raw materials are completed at a time in a hot pressing machine; the weight ratio of an activating agent is optimally set as 1.5%, the water content of a plate blank reaches 20%, the hot pressing temperature reaches 180 DEG C, hot pressing pressure reaches 5 Mpa, hot pressing time is 6 min, the quantity of paraffin emulsion reaches 1.0%, and limiting performance meets the national standard of medium-density fiber boards in GBT11718-2009. The product obtained by implementing the method can be sawn and nailed and is good in machinability, and the defects that natural wood is poor in durability, prone to combustion, damping, corrosion and moth biting and the like are overcome. The shortcomings of pure plastic are overcome. Compared with wood, the environment-friendly waterproof fiber board is good in isotropy, weather resistance and dimensional stability and has the advantages of being firm, tough, durable, resistant to abrasion and the like. In addition, the surface of the environment-friendly waterproof fiber board is easily decorated, the materials of the product can be degraded and recycled, and the product is good in environmental friendliness.

Description

technical field [0001] The invention relates to a method for making an environmentally friendly waterproof fiber board. Background technique [0002] At present, the development and utilization rate of residues such as crop straws in our country is low, and a large amount of straws are burned in the field, which not only causes serious air pollution, destroys the ecological environment, but also wastes valuable renewable resources. In recent years, the country has vigorously promoted Protect the ecological balance and gradually limit the consumption of forest resources; [0003] Traditional synthetic panels have been in operation for decades, but due to market price restrictions and relatively simple raw materials, coupled with the country’s policy of returning farmland to forests and closing mountains for afforestation in recent years, many wood-based panel manufacturers are facing material shortages, resulting in abnormal production and bankruptcy. However, most wood-base...
