Abstract

The invention mainly provides a high-efficiency flame-retardant shaving board processing method. According to the high-efficiency flame-retardant shaving board processing method provided by the invention, moso bamboo is mixed with sundry bamboo, arbor is mixed with the sundry bamboo, and cotton stalks are mixed with sundry stalks to obtain a totally new shaving board base material; and subsequently a fire retardant, a reinforcing agent and flame-retardant resin are added into the shaving board base material. The high-efficiency flame-retardant shaving board processing method provided by the invention solves the problem about formaldehyde release of traditional materials by modifying composite materials of wood shavings by using organic and inorganic materials, so a wood material is reinforced, the water resistance and the weather resistance of a board material are improved, the overall shaving board is endowed with excellent fireproof performance, and thus the shaving board becomes a novel all-powerful super board material; moreover, the cost of the shaving board is equivalent to that of a traditional urea resin pressed shaving board, so the shaving board is extremely high in promotional value, simple in product production process, easy to control and capable of realizing industrialization.

Description

technical field [0001] The invention mainly relates to the field of chipboard processing, in particular to a high-efficiency flame-retardant particleboard processing method. Background technique [0002] Particleboard is formed by hot pressing of shavings with an adhesive. The traditional product adopts surface core layer gradient structure pavement and assembly. It has excellent physical and chemical properties and is easy to process, so it is favored by people. With the advancement of science and technology, derivative series products and deep-processing varieties of particleboard continue to appear and improve, and various functional particleboards are gradually applied in various fields of the national economy. [0003] Particleboard production is inseparable from adhesives. At present, urea-formaldehyde resin adhesives account for more than 90% of the total glue used in the production of particleboard industry, but the defect of urea-formaldehyde resin is that it is no...
