Self-cleaning polyethylene material and preparation method thereof

Abstract

The invention discloses a self-cleaning polyethylene material. The material is prepared from the following components in parts by weight: 30-50 parts of high-density polyethylene, 30-50 parts of silicone rubber, 5-10 parts of benzoxazine, 5 parts of nano-titanium dioxide, 3 parts of a dispersant, and 0.5 part of a heat stabilizer. According to the self-cleaning polyethylene material provided by the invention, two thermosetting materials including the silicone rubber and the benzoxazine that can effectively improve the surface properties of the material are introduced into the polyethylene substrate material through a dynamic vulcanization technology, so that the thermoplastic elastomer material with ultra-low surface energy is prepared; compared with a traditional coating material, the thermoplastic elastomer material provided by the invention has a simpler production process, strong operability, and a wider application range; and the nano-titanium dioxide filler is added into the system, so that the mechanical properties of the material are improved, and the material has stronger catalytic decomposition ability under visible light catalytic conditions, and can purify organic stains attached to the surface of the material.

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a self-cleaning polyethylene material and a preparation method thereof. Background technique [0002] With the improvement of social economic level and people's living standards, people's requirements for material properties are also getting higher and higher. For materials used in daily life, how to improve the durability and decorative properties of materials and reduce the cost of maintenance is an urgent problem in the material industry. The emergence of self-cleaning materials provides a clear direction for solving the above problems. [0003] The emergence of self-cleaning materials benefits from the development of bionics and the continuous improvement of human knowledge of nature. In nature, plant leaves are materials with excellent self-cleaning performance, and the material has a very large contact angle with water. Among the existing self-cleaning materials, most...

AI Technical Summary

Problems solved by technology

Among the existing self-cleaning materials, most of them imitate the hydrophobic surface of plant leaves by reducing the surface energy of the material, but such methods usually appear in the form of coating products, and the material is made hydrophobic by coating. The surface properties of the surface, the process is more, but also did not take into account the differences of various materials
