Problems solved by technology

[0004] However, due to the high production cost of polylactic acid in traditional polylactic acid products, polylactic acid cannot be popularized, and polylactic acid products have poor heat resistance and brittle texture. Therefore, it is urgent to research and develop a low-cost, heat-resistant and flexible Biomass-based composite materials for non-woven fabrics with good performance and degradability

Abstract

The invention discloses a biomass based composite material with high degradability for non-woven fabric and a processing technology of the biomass based composite material, and belongs to the technical field of biodegradable polymer composite materials. The processing technology comprises steps as follows: after sodium alginate and nano-silica are mixed, the mixture is processed by a silane coupling agent KH-550, and modified sodium alginate is prepared; then, oxidized starch and polyallylamine hydrochloride are subjected to a mixed reaction, the modified sodium alginate is added, a stirring reaction is performed, and an additive is prepared; polylactic acid and epoxidized soybean oil are mixed, a catalyst and the additive are added, mixed banburying and pelletizing are performed, and thebiomass based composite material with high degradability for the non-woven fabric is obtained. The biomass based composite material with high degradability for the non-woven fabric has better heat resistance, excellent flexibility and higher degradability and is suitable for preparing the non-woven fabric.

Description

technical field [0001] The invention relates to the technical field of composite materials for non-woven fabrics, in particular to a high-degradability biomass-based composite material for non-woven fabrics and its processing technology. Background technique [0002] With the advancement of science and technology and the development of human civilization, polymer material products, such as plastic bags, lunch boxes, medical and a series of plastic products in daily life, are constantly being produced and become waste. [0003] Since the beginning of the 20th century, a large number of applications of synthetic polymer materials have caused serious environmental pollution, and the search and application of new environmentally friendly polymer materials has received extensive attention from all over the world. In this situation, biodegradable polymer materials are developing rapidly. Practice has proved that biodegradable polymer materials are different from general synthetic...
