Example Embodiment

[0026] Example one

[0027] The first step is to dry the 20-40 mesh jute stalk powder at 90°C with hot air, and control the water content within 3%.

[0028] In the second step, the jute stalk powder of 20-40 mesh is vigorously stirred at 1000-3000 rpm at 90-110°C, while stirring, 0.5% of the weight of the jute stalk powder is added with the silane coupling agent KH550, and the stirring is continued In 10 minutes, the coupled jute stalk powder was prepared.

[0029] In the third step, the 1250 mesh mineral filler calcium carbonate is vigorously stirred at 90-110°C at 1000-3000 rpm, while stirring, 2% stearic acid accounting for the weight of the mineral filler is added, and stirring is continued for 5 minutes to obtain the modified Calcium carbonate.

[0030] In the fourth step, the above-mentioned coupled jute stalk powder and modified calcium carbonate are mixed uniformly in a weight ratio of 100:50 to obtain composite jute stalk powder; extruded and granulated by a special wood...

[0033] Example two

[0034] In the first step, the kenaf stalk powder with 80-100 mesh is dried with hot air at 90°C, and the water content is controlled within 3%.

[0035] In the second step, the kenaf stalk powder of 80-100 mesh is stirred vigorously at 1000-3000 rpm at 90-110°C, and the titanate coupling agent MBJ, which accounts for 1% of the weight of the hemp stalk powder, is added while stirring. -101, continue to stir for 10 minutes to prepare coupled kenaf stem powder.

[0036] In the third step, the 1250 mesh mineral filler talc powder was stirred vigorously at 1000-3000 rpm at 90-110°C, while stirring, stearic acid accounting for 3% of the weight of the talc was added, and the stirring was continued for 5 minutes to obtain a modified product. Sexual talc.

[0037] In the fourth step, the above-mentioned coupled kenaf stalk powder and modified talc powder are mixed uniformly in a weight ratio of 100:10 to obtain composite kenaf stalk powder; extruded and granulated by a...

Example Embodiment

[0040] Example three

[0041] In the first step, the flax stalk flour with 60-80 meshes is dried with hot air at 90°C, and the water content is controlled within 3%.

[0042] In the second step, the flax stalk powder with 60-80 mesh is vigorously stirred at 1000-3000 rpm at 90-110°C, and the aluminum zirconate coupling agent TL accounting for 3% by weight of the flax stalk powder is added while stirring. -4, continue to stir for 20 minutes to prepare coupled flax stalk powder.

[0043] In the third step, 325 mesh calcium carbonate was vigorously stirred at 90-110°C at 1000-3000 rpm, and stearic acid accounting for 4% by weight of calcium carbonate was added while stirring, and the stirring was continued for 6 minutes to obtain modified carbonic acid. calcium.

[0044] In the fourth step, the above-mentioned coupled flax stalk powder and modified calcium carbonate are mixed uniformly at a weight ratio of 100:30 to obtain composite hemp stalk powder; extruded and pelletized by a speci...

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...
