Abstract

The invention relates to the field of foamed plastics, in particular to halogen-free flame retardant polystyrene foam, and solves the problem that the flame retardant function cannot be realized better due to poor high-low-temperature resistance of a foam material in the prior art. The halogen-free flame retardant polystyrene foam comprises components in parts by weight as follows: 100 parts of polystyrene masterbatch, 10-20 parts of organosilicone grafted polystyrene, 3-10 parts of silicone rubber micropowder, 20-30 parts of inorganic filler, 2-10 parts of n-pentane, 4-10 parts of halogen-free flame retardant, 0.15-1 part of a catalyst and 0.1-0.3 parts of dimethyl silicone oil. The halogen-free flame retardant polystyrene foam can be prepared in a conventional foaming mode. The halogen-free flame retardant polystyrene foam has the following advantages: (1), high-temperature resistance and flame-retardant performance are excellent; (2), the polystyrene foam is halogen-free and flame-retardant and cannot produce greasy dirt, harmful substances or substances polluting the environment in a burning process; (3), the mechanical property is excellent, and the impact resistance is strong.

Description

technical field [0001] The invention relates to the field of foamed plastics, in particular to a halogen-free flame-retardant polystyrene foam. Background technique [0002] Polystyrene foam is made of polystyrene resin as the main body, adding foaming agent and other additives. It is currently the most widely used cushioning material. It has a closed-cell structure, low water absorption and excellent water resistance; low density, generally 0.015-0.03; good mechanical strength, excellent cushioning performance; good processability, easy to mold; good colorability, strong temperature adaptability , Excellent anti-radiation and other advantages, and high dimensional accuracy, uniform structure. Therefore, its share in the external wall insulation is very high. [0003] However, ordinary polystyrene foam is extremely flammable and emits styrene gas that pollutes the environment when burned. The maximum working temperature is only 120°C, and it often cannot play its role in ...
