Abstract

The invention discloses biomass resin and a method for preparing a fibre oriented shaving composite board by using the biomass resin as an adhesive. The biomass resin is prepared from, by weight, 100 parts of water, 1-3.5 parts of a compound stabilizer, 5-50 parts of vegetable protein powder, 0.01-0.05 part of a protease additive, 2-10 parts of plant starch, 1-7 parts of modified plant cellulose powder, 0.01-0.05 part of a complex enzyme preparation, 0.1-5 parts of a molecular structure acylation modifier, 0.1-0.5 part of a cross-linking agent, 0.01-10 parts of a resin additive, 0.01-0.05 part of an antifoaming agent, 0.1-0.5 part of a preservative and 5-10 parts of a filler. In addition, the biomass resin is used as an adhesive to be applied in a preparation technology of a fibre oriented shaving composite board. Viscosity is reduced, solid content is raised, and secondary gluing performance after drying of the adhesive is enhanced.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel processing, and in particular relates to a biomass resin and a method for preparing a fiber-oriented strand composite board by using the biomass resin as an adhesive. Background technique [0002] At present, the world's forest resources are increasingly scarce, resulting in a shortage of timber market. The raw materials of my country's timber market have changed from natural forest resources to artificial forest timber, bamboo timber, crop straw and timber processing residues. It not only reduces the logging of forest resources, but also reduces environmental pollution. These woody material resources have the characteristics of scattered sources, difficult collection, small diameter class, and low stacking density. These characteristics determine that in the future, the wood industry will adopt a supply mode in which raw materials are processed into semi-finished products and then tran...
