Abstract

The preparation and product molding process of biodegradable resin composite and modified special resin involves the composite of PBS (polybutylene succinate) and PLA (polylactic acid) biodegradable high molecular polymer. Through the filling modification of modified starch and activated inorganic filler, special resin materials such as injection molding, blow molding, blister molding, and hollow molding can be obtained. It can be processed on existing general plastic molding equipment such as general injection molding equipment, blow molding equipment, blister machines, and extrusion hollow machines. The temperature of the product is above -20-105°C, the performance is excellent, and the biodegradation is >90% within 90 days, which has practical and popularization value.

Description

technical field [0001] The invention relates to a biodegradable resin composite and modified special resin preparation and molding process. Background technique [0002] The development of my country's degradable materials in the 20th century has roughly gone through the following stages: [0003] I) During the 1970s and 1980s, research on additive photolysis of photosensitizers in common plastic resins [0004] II) Application and market development of photodegradable plastics in the mid-1980s [0005] III) 1990-1995, bi-(photo / bio)degradable plastics [0006] IV) After 1995, the market application, inspection and modification of various photo / biodegradable plastic products. Since the popularized and applied degradable materials are inseparable from the use of petroleum resin as a carrier, which is a partially degradable material, the remaining large amount of polyolefins cannot be degraded in the soil for hundreds of years, resulting in the destruction of the soil struc...
