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

Abstract

The invention discloses a PP composite cereal fiber material and a preparation method thereof, and mainly relates to the field of plastic processing. The PP composite cereal fiber material comprises the raw materials: polypropylene, polyethylene, a polyolefin elastomer, white mineral oil, cereal straw powder, barium sulfate, calcium carbonate, an antioxidant 1010, an antioxidant 168, an EBS dispersant, PE wax, titanium dioxide and zinc stearate. The PP composite cereal fiber material has the advantages that use of petroleum resources is reduced, and the advantages of low carbon and environmental protection, easy degradation, superior performance and easy processing are achieved.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a PP composite grain fiber material and a preparation method thereof. Background technique [0002] Petroleum base materials such as polypropylene and polyethylene are widely used in various aspects of industry, agriculture, and life because of their advantages such as low density, high mechanical strength, good chemical resistance, low price, and easy molding. However, its strong dependence on petroleum raw materials and its difficulty in degradation have caused great pressure on resources and environmental protection. [0003] At the same time, my country is a large agricultural country with abundant crop straw resources, but the crop straw has not been well utilized, and to a large extent farmers directly burn it, which causes serious air pollution and is also a waste of resources. Straw burning is easy to cause fire, causing damage and loss to people's lives and property. ...
