AI Technical Summary

Problems solved by technology

Among them, polylactic acid (PLA) and phthalic acid-adipate-butylene glycol ester (PBAT) are the two most widely used biodegradable materials at the present stage of industrialization and application. However, when the above-mentioned single materials are used on films, The comprehensive physical and chemical properties are poor, and it cannot achieve the use effect of the existing HEPE+LLDPE and LDPE+LLDPE plastic films on the market. In addition, the cost of raw materials has always been high, so it is difficult to be truly accepted by the market.

Abstract

The invention relates to the field of fully biodegradable plastics, and discloses a talcum powder filled full-biodegradable film blowing material which comprises the following components in parts by mass: 50-60 parts of PBAT (Polybutylene Terephthalate); 5 to 20 parts of PLA; 10 to 30 parts of talcum powder; 0.1 to 0.5 part of a chain extender; 0.1 to 0.5 part of a coupling agent; and 0.5-2 parts of a lubricant. The invention further discloses a preparation method of the fully biodegradable film blowing material filled with the talcum powder. The special film blowing material disclosed by the invention is relatively low in cost, good in processability and applicable to a common LDPE film blowing machine, and a prepared film product is excellent in physical performance and has relatively high application value.

Description

technical field [0001] The invention relates to the field of biodegradable plastics, relates to a talcum powder-filled biodegradable blown film material, and also relates to a preparation method of the talcum powder-filled biodegradable blown film material. Background technique [0002] Since its birth, petroleum-based plastics have penetrated into all areas of human life. According to statistics, China uses more than 3 million tons of discarded plastics every year. Take disposable plastic film products as an example. After being used and discarded in the natural environment, they will not decompose even after hundreds of years. [0003] At present, plastics are mainly disposed of by incineration or burial, which will produce a large amount of toxic and harmful gases or pollute the quality of soil and groundwater, causing irreversible pollution to the environment. [0004] In this context, fully biodegradable materials, as environmentally friendly products that are most li...
