Flame-retardant PP (propene polymer) foaming plate and preparation method thereof

Abstract

The invention discloses a flame-retardant PP (propene polymer) foaming plate and a preparation method thereof. The flame-retardant PP foaming plate comprises, by weight, 85-100 parts of polypropylene, 40-60 parts of brominated polystyrene, 34-48 parts of aluminum ash, 25-35 parts of red mud, 20-30 parts of chlorinated polypropylene, 17-23 parts of dawsonite, 19-27 parts of oil shale residues, 10-15 parts of decabromodiphenyl ether, 2-3 parts of p-toluenesulfonhydrazide, 8-14 parts of antimony phosphite, 5-10 parts of zinc aluminate, 5-10 parts of ferrocene, 10-15 parts of ammonium phosphomolybdate, 12-18 parts of pentaerythritol bis-dimethyl silicate ester, 1-2 parts of trihydrazine s-triazine, 3-6 parts of dibasic lead stearate, 4-9 parts of citric acid and 11-17 parts of ethylhexyl diphenyl phosphate. According to the foaming plate, the brominated polystyrene, the decabromodiphenyl ether, the dawsonite, the pentaerythritol bis-dimethyl silicate ester and the like are added and serve as flame retardants, the zinc aluminate, the ferrocene, the ammonium phosphomolybdate and the like are added and serve as smoke suppressants, the raw materials mutually cooperate, the oxygen index of the PP foaming plate is improved, the smoke amount of the PP foaming plate is reduced, and physical and mechanical properties of products cannot be affected.

Description

technical field [0001] The invention relates to a PP foam board and a preparation method thereof, in particular to a flame-retardant PP foam board and a preparation method thereof. Background technique [0002] PP foam board, also known as polypropylene foam board, its chemical composition is polypropylene (Polypropylene). PP foam board has excellent processability due to its excellent thermal stability and dimensional stability of products under high temperature, suitable and soft surface, excellent microwave adaptability and degradability. It can also adjust related performance according to product performance and use, and can be widely used in auto parts, equipment manufacturing, stationery, packaging, building materials and other fields. [0003] In recent years, PP foam boards have developed rapidly, and a wide variety of PP foam boards with different properties have appeared on the market. However, compared with the performance of foreign PP foam boards, there is s...
