Vegetable fiber reinforced flame-retardant thermoplastic starch-based composite material and preparation method thereof

Abstract

The invention belongs to a vegetable fiber reinforced flame-retardant thermoplastic starch-based composite material and a preparation method thereof. The composite material comprises the following raw materials in part by weight: 100 to 120 parts of starch, 30 to 50 parts of plasticizer, 5 to 30 parts of vegetable fibers and 5 to 40 parts of flame retardant. The banana fiber raw material used by the invention is agricultural waste, namely banana stems, and has low cost; and sisal fibers, jute fibers and the like can be produced industrially and the raw materials are easily obtained. The product can be prepared by simple controllable standard machine-shaping conditions. The finished product has excellent biodegradability, mechanical property and flame retardant property, can be used in the fields of package, automotive trim, household appliances and the like and avoid applying pressure to the environment after being scrapped. Meanwhile, the vegetable fiber reinforced flame-retardant thermoplastic starch-based composite material increases the additional value of the cash crops, increases farmer income and has important significance for reduction of white pollution.

Description

technical field

[0001] The invention relates to the field of natural raw starch composite materials and thermoplastic processing thereof, in particular to plant fiber reinforced flame-retardant thermoplastic starch-based composite materials and a preparation method thereof. Background technique

[0002] Since Leo Baekeland invented phenolic plastics in the early 20th century, plastics have been applied to all aspects of people's lives in more than 100 years, completely changing human life, and are recognized as a particularly important one among the 100 major inventions of mankind. In 1996, global plastic production had exceeded 130% of steel production (according to total production volume). In 2001, my country's output of plastic products ranked second in the world, and in 2007 it increased to 31.8454 million tons (according to China Statistical Yearbook 2008). While plastic brings comfort and convenience to people, it also brings environmental pollution hazards to humans...
