New plastic modified material

Abstract

The invention discloses a new plastic modified material characterized by including the following materials: by weight, 9-15 parts of thermoplastic resin, 5-13 parts of polypropylene, 25-30 parts of a plasticizer, 2-3 parts of a film forming assistant, 5-8 parts of a polyacrylic emulsion, 1 - 9 parts of a filler, 1 - 3 parts of fiber aquatic stone, 11 - 24 parts of redispersible emulsion powder, 2 - 9 parts of red phosphorus powder, 3-8 parts of a lubricant and 15 - 20 parts of carbon black powder. The new plastic modified material contains no halogen, is friendly to the environment, can produce great environmental protection benefits, and has good flame retardant performance, high safety, good tensile strength, high bending strength, high impacting strength, thermal deformation resistant temperature and other physical and mechanical properties, and TV casings produced by application of the plastic modified material are strong in shock resistance and long in service life, and can be recycled.

Description

technical field [0001] The invention relates to a novel 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
