Abstract

The invention discloses flame-retardant polypropylene plastic. The flame-retardant polypropylene plastic comprises the following component in parts by weight: 70-80 parts of polypropylene resin, 40-50 parts of a fire retardant, 10-20 parts of terpene resin, 8-12 parts of nano-titania and 0.2-0.8 part of an antioxidant. By adding the fire retardant prepared by mixing ammonium polyphosphate, grafted maleic anhydride and nano-clay into the flame-retardant polypropylene plastic, ammonium polyphosphate and nano-clay in a compound flame-retardant polypropylene system can be uniformly dispersed, so that the flame-retardant efficiency is obviously improved, the crystallization property of a polypropylene matrix can be improved, and the tenacity of a material is improved.

Description

Technical field [0001] The invention relates to the field of plastics, in particular to a polypropylene flame-retardant plastic. Background technique [0002] Polypropylene (PP) is one of the largest resins in the world and is widely used in many industries such as packaging, textiles, building materials, automobiles, electronics / electrical appliances, and office supplies. However, one of its shortcomings that cannot be ignored is its flammability. For PP flame retardant, traditional flame retardants such as halogen, phosphorus and inorganic hydroxides are still used in the industrial field. However, because some halogen-based flame retardants pose a potential threat to the environment, the development of environmentally friendly flame retardants is currently an important development direction. As an emerging environmentally friendly flame retardant system, phosphorus-nitrogen intumescent flame retardants have become a research hotspot in flame-retardant polypropylene materials....
