Problems solved by technology

However, the oxygen index of polypropylene is low, only 17.4. It is easy to burn, has a fast burning rate, and has a large calorific value. When burning, it is accompanied by melt dripping, which is easy to cause fire and has unsafe factors, which limits its application in many fields. application
[0003] In order to enhance the flame retardancy of polypropylene products, only flame retardants can be added, but the addition of flame retardants will often reduce the mechanical properties of the products, making these products prone to stress, cracking, and impact resistance to notches. Low strength, poor wear resistance, poor fluidity, easy aging and other shortcomings, the product reliability is insufficient

Abstract

The invention discloses flame-retarding PP including, by weight, 60-80 parts of PP copolymerized resin, 12-18 parts of environment-friendly bromine / antimony composite flame-retarding agent, 6-10 partsof a compatibilizer, 1-4 parts of an antioxidant, and 0.5-2 parts of a heat-resistant stabilizer. The invention also discloses a preparation method of the flame-retarding PP. In the invention, the flame retarding effect of the flame-retarding PP is significantly improved, and the flame-retarding PP is improved in impact toughness and low temperature resistance at the same time. The flame-retarding PP can be applied to the field, with high requirements, such as home appliances, machinery, automobiles, etc.

Description

technical field [0001] The invention relates to the field of flame-retardant materials, in particular to a flame-retardant PP and a preparation method thereof. Background technique [0002] Polypropylene (PP) is widely used in automobiles, home appliances, textiles, construction and other industries due to its excellent mechanical properties, good electrical insulation, chemical corrosion resistance, and light weight. However, the oxygen index of polypropylene is low, only 17.4. It is easy to burn, has a fast burning rate, and has a large calorific value. When burning, it is accompanied by melt dripping, which is easy to cause fire and has unsafe factors, which limits its application in many fields. application. [0003] In order to enhance the flame retardancy of polypropylene products, only flame retardants can be added, but the addition of flame retardants will often reduce the mechanical properties of the products, making these products prone to stress, cracking, and im...
