Problems solved by technology

[0009] In addition, in biosynthetic resins, the resin matrix can be general-purpose resins such as PE, PP, PET, PVC, PS, etc. These resins contain a small amount of polar groups and are hydrophobic, and the main component of biomass as a filler is Cellulose, lignin and hemi-lignin contain more polar groups on the surface, such as hydroxyl groups, which are hydrophilic, so the interfacial compatibility between the two is poor, and it is difficult to form a good wetting and interface binding
In addition, biomass micropowder is a porous solid with tiny pores on the surface and inside, and it is difficult for resins with poor compatibility with biomass to penetrate and wet the inside of the pores, which makes it easy to produce interface defects between biomass and resin , which further increases th

Abstract

The invention discloses biologically-synthesized resin capable of controlling interfacial compatibility and application thereof and relates to biologically-synthesized resin and application thereof. The biologically-synthesized resin is prepared by, by weight percentage, 30-50% of resin, 0.5-5% of compatilizer, 0.5-3% of lubricating agent, 0.5-3% of oxidant and the balance of filler. The biologically-synthesized resin can be used for preparing degradable materials. By the preparation method of the biologically-synthesized resin, the surface appearance of biomass micro-powder can be controlled, good interfacial compatibility between the biomass micro-powder and a nonpolar resin base can be achieved, good moistening and interfacial combination between the biomass micro-powder and the nonpolar resin base can be achieved, interface combination strength is increased, internal defects of biologically-synthesized resin products are reduced, interface thickness is controlled, occlusion of the resin base on the surface and inside biomass is reduced, and the mechanical strength, stability, machinability, flexibility and ductility of the biologically-synthesized resin products are guaranteed.

Description

technical field [0001] The present invention relates to a method for increasing the interfacial compatibility of biomass with general resins through the use of compatibilizers and self-assembly of nanoparticles. Background technique [0002] With the increasingly prominent problem of plastic pollution, degradable plastics are gradually favored by the market. According to statistics, the demand for degradable plastics in foreign markets will grow rapidly at a rate of 20% per year. Degradable plastics can be divided into photodegradable plastics, biodegradable plastics, chemically degradable plastics, combined degradable plastics, etc. according to the environmental conditions that cause degradation. [0003] At present, the degradable plastics in the world mainly include three categories: aliphatic polyester degradable plastics, plastic starch and starch-based degradable plastics, and highly filled plastics with degradable modifiers added. [0004] Aliphatic polyesters main...
