High-strength polystyrene

Abstract

The invention discloses high-strength polystyrene, and belongs to the technical field of high molecular organic matter. The high-strength polystyrene is composed of the following substances: 800-1000parts of polystyrene, 10-12 parts of clay, 50-55 parts of straw ash, 2-3 parts of ascorbic acid, 1-2 parts of silane coupling agent KH550, 1-3 parts an anti-dripping agent, 2-5 parts of antimony trioxide, 1-2 parts of nano carbon powder, 2-3 parts of tributyl citrate, 4-5 parts of sodium selenite, 5-6 parts of cuttlefish bone powder, 1-3 parts of hydrated magnesium hydroxide, 2-4 parts of decabromodiphenyl ether, and 2-5 parts of diffusion oil. The polystyrene foam provided by the invention has an excellent flame-retardant effect, gives excellent mechanical properties to a polystyrene foam material, has high strength and a low density, and maintains the advantages of thermal insulation, a light mass, a low water absorption rate and the like of the polystyrene foam material.

Description

technical field [0001] The invention relates to a high-strength polystyrene, which belongs to the technical field of high molecular organic matter. Background technique [0002] Expanded polystyrene resin is a foam material with low density and thermal insulation properties first invented by BASF in the early 1940s. The structure of expanded polystyrene resin is characterized by large specific surface area, and the internal structure of the material is cell-like, and between the cells are cell walls, pillars or polystyrene films, and most of the internal volume of the material is occupied by air. When it catches fire, it is very easy to spread the flame. Therefore, the flame retardancy of expanded polystyrene resin products is much more difficult than other common resin materials. Moreover, when expanded polystyrene resin burns, it will produce an orange flame, emit the smell of styrene, and be accompanied by a large amount of black smoke, which is very toxic. The flame r...

Problems solved by technology

Moreover, when the expanded polystyrene resin burns, it will produce an orange flame, emit the smell of styrene, and be accompanied by a large amount of black smoke, which is very toxic

Existing flame retardant foaming materials, their flame retardant properties are still not ideal, and cannot meet some occasions with high fire protection requirements, and are still subject to some limitations in use

At the same time, other mechanical properties of the existing polystyrene foam also need to be further improved
