Abstract

The invention discloses a biochar-based thermosetting resin composite material and a preparation method thereof. The preparation method of the biochar-based thermosetting resin composite material comprises the following steps: (1) pre-treating a biochar raw material, specifically directly taking crushed biochar powder; (2) uniformly mixing the crushed biochar powder with thermosetting resin (one or more selected from epoxy resin, phenolic resin, amino resin, urea resin, unsaturated polyester resin and the like), a curing agent and the like; (3) carrying out filling; and (4) carrying out curingand forming. The preparation method of the biochar-based thermosetting resin composite material is simple in process and is environmentally friendly, the prepared biochar-based thermosetting resin composite material is high in mechanical performance, and high-value comprehensive utilization of renewable biomass resources is achieved.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a biochar-based thermosetting resin composite material and a preparation method thereof. Background technique [0002] Biochar, also called biomass char and biomass coke, is a kind of highly aromatized refractory solid object produced by high-temperature pyrolysis and carbonization of plant biomass under complete or partial anoxic conditions. It belongs to a type of black carbon. types. Biochar is a new type of environmentally friendly material with wide sources, degradability, low cost, large specific surface area, good adsorption, etc. The prepared composite materials are widely used in carbon sequestration and emission reduction, water purification, heavy metal adsorption , soil improvement, high-quality energy and other daily life. Therefore, it has broad market prospects and good social and economic benefits. [0003] The use of biochar to prepare composite materials is...
