Abstract

The present invention discloses preparation process of composite material of hemp stalk and plastic. The composite material is prepared through mixing hemp stalk powder and mineral powder to obtain composite hemp stalk powder, extruding and pelletizing to obtain composite hemp stalk pellet, mixing with plastic, and pelletizing or extruding into product. The composite material is environment friendly, reusable and low in cost.

Description

technical field [0001] The invention belongs to the technical field of natural fiber composite materials and wood-plastic composite materials, and specifically refers to a preparation method of hemp stem and plastic composite materials. Background technique [0002] my country is a big hemp-producing country in the world, rich in hemp resources. According to statistics, the average annual planting area of ​​hemp, kenaf, jute and flax is 200,000 to 250,000 hectares, and the output ranks third in the world. Hemp, jute, flax and kenaf are all annual herbaceous plants. For example, jute is mainly produced in India and Bangladesh, and there are also a lot of planting areas in my country. Jute stems are 2 to 5 meters high, the fibers are white and shiny, and have good water absorption. They are used for making linen, sacks, ropes and carpets. Usually, people mainly use the bast fiber part of hemp as the fiber raw material of textiles, or use chopped hemp fiber to prepare natural...
