Abstract

The invention relates to the technical field of plate manufacturing, in particular to a preparation method of an environment-friendly plate. The preparation method comprises the steps of basic fiber preparation, reinforced fiber preparation, bonder preparation, preparation of an inflaming retarding reinforcing agent, preparation of a curing agent, material mixing and plate preparation. According to the preparation method of the plate, waste is utilized repeatedly; the preparation method is green and environment-friendly; the prepared plate is good in mechanical strength and has excellent mouldresistance and inflaming retarding performance; no harmful gas is released; the production process is controllable; the plate is poisonless and harmless and is suitable for batch production; and highpractical value and good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of modern papermaking, in particular to a preparation method of an environmentally friendly board. Background technique [0002] On the one hand, wood has always been favored by humans. Its natural texture, texture, structural mechanical properties, and ease of processing are irreplaceable by other materials, and it is widely used in furniture manufacturing and building materials industries. However, the material of some wood, especially plantation wood, cannot meet the needs of the public. For example, its structure is relatively loose, low density, easy to be eaten by insects, bacterial erosion, acid, alkali and weathering degradation, etc. Therefore, the application of composite boards was born, and now Some raw materials in the board are too single, and the prepared board has poor pressure resistance and mechanical properties. [0003] On the other hand, wood flame retardant is a method of improving the...
