Modified environment-friendly plastic with high elasticity

Abstract

The invention discloses a modified environment-friendly plastic with high elasticity. The modified environment-friendly plastic comprises the following raw materials in parts by weight: 50-60 parts of ethylene-vinyl acetate copolymer, 45-55 parts of polyethylene resin, 18-22 parts of hydroxybutyrate-hydroxyvalerate copolyester, 12-15 parts of modified poly-beta-hydroxybutyric acid, 15-20 parts of oxidized starch, 10-15 parts of styrene-butadiene-styrene block copolymer, 1.5-1.8 parts of carbon fibers, 3-4 parts of cotton fibers, 1.1-1.3 parts of silane coupling agent, 2-3 parts of methylparaben, 1.1-1.6 parts of potassium sorbate, 2-2.2 parts of epoxy fatty acid octyl ester, 5-7 parts of tricresyl phosphate, 6-8 parts of precipitated barium sulfate, 3-5 parts of calcined kaolin, 23-26 parts of fumed titania and 1-1.4 parts of antioxidant. The modified environment-friendly plastic has high elasticity and excellent tensile strength, elongation at break and thermal aging property and can not cause irreversible harms to the environment.

Description

technical field [0001] The invention relates to the technical field of environment-friendly plastics, in particular to a modified environment-friendly plastic with high elasticity. 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 at present, they have not been widely promoted and applied because their degradability and other performances are not v...

[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.
