Abstract

The invention relates to the technical field of packaging materials, in particular to a high-strength wear-resistant composite packaging material and a preparation method thereof. The high-strength wear-resistant composite packaging material is prepared from, by weight, 80-120 parts of chlorinated butyl rubber, 60-80 parts of polyvinyl chloride resin, 20-40 parts of carbon nanofibers, 4-8 parts of graphene, 8-12 parts of glass fibers, 18-22 parts of carbon fibers, 16-20 parts of ultra-high molecular weight polyethylene fibers, 3-9 parts of plasticizer, 4-8 parts of methyl silicone oil. 8-12 parts of bamboo fiber, 4-8 parts of a compatibilizer. Through the carbon nanofibers, the glass fibers, the carbon fibers and the ultra-high molecular weight polyethylene fibers, the strength, the stability and the wear resistance of the composite packaging material can be relatively high; and through the methyl silicone oil and the bamboo fibers, the composite packaging material has excellent heat resistance, electrical insulating property, weather resistance, hydrophobicity, physiological inertness and small surface tension, and also has a low viscosity-temperature coefficient and high compression resistance, so that the overall using effect is better.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a high-strength wear-resistant composite packaging material and a preparation method thereof. Background technique [0002] Packaging materials are widely used in packaging containers, packaging decoration, packaging printing, packaging and transportation, etc., which play an important role in industrial production and people's daily life. With the continuous development of my country's industrialization, the types and production of industrial products are increasing year by year, and the annual consumption of packaging materials is also increasing. Therefore, the demand for packaging materials in our society has risen sharply. However, although there are many types of existing packaging materials, the existing packaging materials have poor wear resistance and antistatic properties, poor heat resistance, electrical insulation, weather resistance, and compression resis...
