Green plastic modified material

Abstract

The invention discloses a green plastic modified material. The green plastic modified material comprises the following substances in parts by weight: 9-15 parts of thermoplastic resin, 5-13 parts of polypropylene, 25-30 parts of a plasticiser, 2-3 parts of a coalescing agent, 2-5 parts of octahydrate, 3-7 parts of silicic ester, 1-2 parts of clay, 3-7 parts of methyl trimethoxysilane, 11-14 parts of poly-4-methyl-1-pentene, 3-8 parts of butadiene and 2-8 parts of phenethylene. The plastic modified material provided by the invention does not contain halogen and is environmental-friendly, can create very high environment protection benefits, has a good flame retardant property, and is high in safety and good in physical mechanical properties such as tensile resistance strength, bending resistance strength, shock resistance strength and heat deformation temperature resistance property; a television housing made of the plastic modified material is stronger in anti-impact property and long in service life, and can be recovered for reuse.

Description

technical field [0001] The invention relates to a green plastic modified material. Background technique [0002] High-impact polystyrene (HIPS) is one of the five most commonly used general-purpose plastics in industrial production. It has the advantages of low specific gravity, easy molding and processing, and easy coloring. It is widely used in electronics, electrical appliances, automobiles, home appliances, toys, etc. Industry, especially in the field of TV casings, has been at the forefront of various plastic materials. With the development of TV technology, the size of flat-panel TVs is getting larger and larger, and HIPS has also achieved rapid development in the field of TV casings. [0003] However, because the TV casing made of high-impact polystyrene (HIPS) is easy to burn under an open flame, a large amount of smoke and toxic gases are generated, and there are great safety hazards. People continue to study the ability to endow high-impact polystyrene ( HIPS) Fla...

Problems solved by technology

[0003] However, because the TV casing made of high-impact polystyrene (HIPS) is easy to burn under an open flame, a large amount of smoke and toxic gases are generated, and there are great safety hazards. People continue to study the ability to endow high-impact polystyrene ( HIPS) Flame-retardant HIPS plastic modified materials with flame-retardant and self-extinguishing properties. In the past, flame-retardant HIPS plastic modified materials added halogen bromine and antimony inorganic compounds to high-impact polystyrene (HIPS) as flame retardants. , so that the obtained modified material has the performance of flame retardancy

[0004] In order to achieve good flame retardancy, the addition of halogen bromine and antimony is more, which not only leads to high production costs, but also has a serious impact on the physical and mechanical properties of the modified material, resulting in the tensile strength, Bending strength, impact strength, heat distortion temperature and other properties have dropped significantly, resulting in poor impact resistance and short service life of TV casings made of flame-retardant HIPS plastic modified materials. What is more serious is flame-retardant HIPS plastic modified materials. The halogen contained in the material will cause serious harm to the ozone layer of the atmosphere, especially with the improvement of environmental protection standards in various countries, it is required to reduce or eliminate the use of halogen-containing flame retardants, and halogen-containing materials will gradually be eliminated because they do not meet environmental protection requirements
