High-strength shock-resistant environment-friendly modified plastic

Abstract

The invention discloses a high-strength shock-resistant environment-friendly modified plastic which is composed of the following components in parts by weight: 30-45 parts of polyolefin resin, 20-30 parts of PE (polyethylene), 5-9 parts of ethylene copolymer elastomer, 1-2 parts of dispersant, 1-5 parts of polyether glycol, 25 parts of toluene diisocyanate, 2-5 parts of chlorobenzoate, 2-3 parts of white carbon black, 2 parts of kaolin, 2 parts of pigment, 3 parts of thickener and 9 parts of dispersant. The environment-friendly material disclosed by the invention has favorable mechanical properties, such as bending and tension modulus, notch impact strength, ultraviolet resistance and cold / heat shock resistance, and favorable degradability, and is easy to process.

Description

technical field [0001] The invention relates to an environment-friendly modified plastic with high strength and impact resistance. Background technique [0002] Existing products made of polypropylene resin or polyethylene resin are all injection molded with pure polypropylene resin or polyethylene resin. The mechanical properties and degradability of resisting cold and heat shock are not very good, especially as people pay more and more attention to environmental protection, the requirements for the degradation performance of plastic products are getting higher and higher. Therefore, the traditional polypropylene resin or Products made from polyethylene resins are increasingly subject to market and government constraints. Although, there are some degradable polypropylene resin or polyethylene resin products to appear at present, but because their degradability and other properties are not very satisfactory, they have not been widely promoted and applied.

[0002] Existing products made of polypropylene resin or polyethylene resin are all injection molded with pure polypropylene resin or polyethylene resin. The mechanical properties and degradability of resisting cold and heat shock are not very good, especially as people pay more and more attention to environmental protection, the requirements for the degradation performance of plastic products are getting higher and higher. Therefore, the traditional polypropylene resin or Products made of polyethylene resin are increasingly subject to market and government restrictions

Although some degradable polypropylene resin or polyethylene resin products have appeared at present, they have not been widely promoted and applied due to their unsatisfactory degradability and other properties.
