Problems solved by technology

It overcomes the problem of poor environmental stress cracking resistance of the existing unmodified high-density polyethylene material, and at the same time increases the flexibility and processability of the material. However, the modified polyethylene material requires the selection of materials Too high, not conducive to actual production, and it is mainly used in steel pipe materials, poor flexibility and other properties, not conducive to the preparation of bionic rattan materials, and it also has the technical problem of poor anti-aging performance

Abstract

The invention relates to a polyethylene composite material used for bionic vine, belongs to the technical field of materials and aims at solving the technical problems that in the prior art, the polyethylene composite material is bad in fracture-resistant strength, low in aging-resistant capacity, high in possibility of breaking and bad in flow performance. The polyethylene composite material disclosed by the invention is prepared mainly from the following raw materials by weight percent: 85%-95% of high pressure polyethylene, 1.0%-5.0% of low pressure polyethylene, 0.5%-1.5% of polyisobutene, 3.0%-10% of flexibilizer, 0.1%-0.6% of antioxidant, 0.1%-0.6% of anti-ultraviolet agent and one or two of 1.0%-5.0% of titanium pigment and 1.0%-5.0% of toner. The polyethylene composite material disclosed by the invention has the advantages of good flow performance, good flexibility, strong aging-resistant performance and good aesthetic property; and the aging-resistant time of the polyethylene composite material at least achieves more than five years, and the breaking-resistant strength of the polyethylene composite material achieves more than 400MPa.

Description

technical field [0001] The invention relates to a composite material, in particular to a polyethylene composite material used for bionic rattan, and belongs to the field of material technology. Background technique [0002] With the continuous improvement of living standards, people's requirements for living environment are also getting higher and higher. For example, some green elements, such as natural plants or bionic materials, are added to the office space or interior decoration. At present, the above two materials are mainly used in the market. However, due to the extensive use of natural plants such as natural vines, to a certain extent, the lack of natural resources has affected the ecological environment. Therefore, the generation of bionic materials such as bionic vines to replace natural resources has become the dominant position in today's market . However, because the existing materials used to prepare bionic plants such as bionic rattan mainly use polypropyle...
