Plant fiber particle-filling regeneration polyester composite material and preparation method thereof

Abstract

The invention relates to a plant fiber particle-filling regeneration polyester composite material and a preparation method thereof. The plant fiber particle-filling regeneration polyester composite material is prepared by, by weight, 50-80% of regeneration polyester, 10-20% of polyolefin, 5-30% of plant fiber particles, 2-10% of compatilizer, 2-8% of chain extender, 0.2-1% of antioxygen and 0.2-2% of lubricating agents. The raw materials are fused and then particles are squeezed out and the plant fiber particle-filling regeneration polyester composite material is obtained. According to the plant fiber particle-filling regeneration polyester composite material and the preparation method thereof, the performances (tenacity, transparency and the like) are excellent, sources for raw materials are wide, cost is low, recycling and reusing are available, environment pollution is reduced, and resources are saved. Compared with various inorganic and synthetic fibers, the plant fiber particles have the advantages of being low in price, easy to obtain, low in density, high in tensile strength and modulus, and small in energy consumption for processing, renewable and compatible with the ecological environment, small in environment pollution, small in damage to human bodies, and capable of meeting requirements of the ecological environment, large in economic potential, and applicable to the fields such as automobile industries, interior decoration, and electric products.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a plant fiber particle-filled recycled polyester composite material and a preparation method thereof. Background technique [0002] Polyester materials (such as PC, PET, PBT, etc.) are a class of excellent engineering plastics, with good impact resistance and processing performance, and high industrial application value, so they are widely used in CDs, disposable packaging bottles , Textile and other industries. While bringing convenience to people's lives, it also produces a large amount of non-degradable garbage, causing increasingly serious environmental pollution. The recycling and reuse of waste PET beverage bottles and PC disc materials has also attracted people's attention. It can not only reduce environmental pollution, but also save resources and comply with low-carbon environmental protection. [0003] Compared with many inorganic and synthetic ...

Problems solved by technology

[0004] At present, most of the recycling of polyester materials in China is still in the early stage of recycling and reprocessing. Such products have low technical content, low added value, and product performance cannot meet the requirements for use. Moreover, recycled polyester materials are still being used and processed. Easy to degrade during the process, and the stability is not guaranteed
