Problems solved by technology

my country consumes a large amount of wood every year, and Douglas pine is one of them, resulting in a large amount of leftover materials. If these leftover materials are not used, they will not only have no economic value, but will also cause a burden on the environment.

Abstract

The invention provides a preparation method of a composite biomass degradable board. The preparation method comprises the following steps that bamboo shoot shells are taken, cleaned then dried and crushed into particles of 0.2-0.5mm to obtain the bamboo shoot shell fiber particles; Douglas fir trunk scraps are taken, cleaned, soaked for 72-82h in clear water at the room temperature, then taken outto be transferred to a grinding machine for grinding for 5-8 min to obtain Douglas fir trunk fiber; 10wt%-20wt% of the bamboo shoot shell fiber particles and 80wt%-90wt% of Douglas fir trunk fiber are uniformly mixed, and poured into a mold; and hot pressing is conducted at the temperature of 110 DEG C, and the pressure of 5-8 MPa for 2-2.5h so as to obtain the composite biomass degradable board.The composite biomass degradable board prepared by the method has the advantages that under the condition that no chemical adhesives are added, safety and environmental protection are achieved, and good mechanical properties are achieved at the same time.

Description

technical field [0001] The invention relates to a preparation method of a composite biomass degradable plate. Background technique [0002] Since the beginning of the 21st century, the global timber supply has been unable to meet the growing demand. At the same time, the rapid economic development has led to the crisis of fossil energy such as oil. Therefore, human life and social development increasingly require new composite materials with high performance, multi-function and high added value, especially biomass materials, which use biomass as raw material and adopt reasonable processing methods to obtain a series of new composite materials. , Applied to people's lives and various sectors of the national economy. Biomass material emerges at the historic moment in this situation. The so-called biomass materials refer to the renewable resources produced by the photosynthesis of carbon dioxide through plants as raw materials. After production and use, they can be degraded i...
