Problems solved by technology

[0004] In the prior art, there are some products that introduce straw into plastic raw materials, but due to the granules produced by the existing technology, in the subsequent processing, there are problems such as poor dispersion, color spots in the post-processed products, and unsmooth demoulding. This pellet cannot be widely used

Embodiment 1

[0059] Example 1: PP composite grain and wheat fiber material

[0060] The raw materials are: 36 parts of polypropylene V30G; 1.5 parts of polyethylene 7042; 1.2 parts of polyolefin elastomer; 0.2 parts of white mineral oil; 34 parts of wheat straw powder; 10 parts of barium sulfate; 10 parts of calcium carbonate; 0.2 part; 0.2 part of antioxidant 168; 0.2 part of EBS dispersant; 0.4 part of polyethylene wax; 1.3 part of titanium dioxide; 0.3 part of zinc stearate.

[0061] During specific processing, the prepared granules (polypropylene V30G, polyethylene, 1.2 parts of polyolefin elastomer, wheat straw powder), powders (barium sulfate, calcium carbonate, titanium dioxide) and other additives are mixed in a mixer Mix evenly, and then pour it into the feed port of the extruder. The speed of the main machine is 550r / min±10. Melting and polymerization are realized by the three-stage control of the extruder. The three stages are melting section-polymerization and plasticizing sect...

Abstract

The invention discloses a PP composite grain fiber material and a preparation method thereof, and mainly relates to the field of plastic processing. Its raw materials include polypropylene, polyethylene, polyolefin elastomer, white mineral oil, wheat straw powder, barium sulfate, calcium carbonate, antioxidant 1010, antioxidant 168, EBS dispersant, PE wax, titanium dioxide, hard Zinc fatty acid. The beneficial effect of the invention is that it reduces the use of petroleum resources, and has the advantages of low-carbon environmental protection, easy degradation, superior performance and easy processing.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a PP composite grain and wheat fiber material and a preparation method thereof. Background technique [0002] Petroleum substrates such as polypropylene and polyethylene are widely used in industry, agriculture, and life due to their low density, high mechanical strength, good chemical resistance, low price, and easy molding. However, it is highly dependent on petroleum raw materials and difficult to degrade, which has caused great pressure on resources and environmental protection. [0003] At the same time, my country is a big agricultural country with abundant crop straw resources, but crop straws are not well utilized, and are largely burned directly by farmers, which causes serious air pollution and is also a waste of resources. Straw burning can easily lead to fires and cause harm and loss to people's lives and properties. One of the effective ways to solve this problem ...
