Embodiment 1

[0039] Open 45 parts of hemp fibers with a length of 50 mm, and open 55 parts of PBAT fibers with a length of 70 mm. After the opening, the two fibers are pre-mixed, and the fibers are formed into a net. Lay the netted natural fibers and PBAT fibers. layer; the fiber mat will not scatter after being punched by a needle punching machine; the obtained fiber mat is properly cut, layered, and hot-pressed. The relevant performance tests are shown in Table 1.

Embodiment 2

[0041] Open 30 parts of silk fibers with a length of 70 mm, and open 70 parts of PBAT fibers with a length of 100 mm. After the opening, the two fibers are premixed, and the fibers are formed into a web. layer; the fiber mat will not scatter after being punched by a needle punching machine; the obtained fiber mat is cut, layered, and hot-pressed. The relevant performance tests are shown in Table 1.

Embodiment 3

Abstract

The invention discloses a completely degradable high shock resistance composite which comprises the following components in parts by weight: 20-80 parts of natural fiber and 20-80 parts of poly(butyleneadipate-co-terephthalate) (PBAT) fiber. The invention further discloses a preparation method and an application of the completely degradable high shock resistance composite. The composite adopts the PBAT fiber as a base material, so that the composite has very excellent shock resistance and is not easy to break. In addition, a reinforcing phase and a base body of the composite are degradable materials, so that the composite is less harmful to an environment, cannot result in white pollution, and meets a requirement of sustainable development.

Description

technical field [0001] The invention relates to the technical field of polymer modification, in particular to a fully degradable high impact-resistant composite material and its preparation method and application. Background technique [0002] The current white pollution has brought huge social and ecological problems to human beings. Among them, non-degradable plastics prepared from polymer compounds such as polystyrene, polypropylene, and polyvinyl chloride are one of the main culprits causing white pollution. The best way to solve this problem is to research and develop new degradable plastics, and use them to replace non-degradable plastics on appropriate occasions. At present, the degradable plastics that have been studied more include polylactic acid (PLA), poly-3-hydroxyalkanoate (PHA), poly-ε-caprolactone (PCL) and polybutylene succinate (PBS). The research on PLA is relatively comprehensive, and the performance research in various aspects is very sufficient. The r...
