Embodiment 1-3

[0018] A kind of super-tough flame-retardant PP, the raw materials are weighed and mixed evenly according to the weight ratio (see Table 1 for the formula), discharged, and then extruded and granulated with a twin-screw extruder to obtain super-tough flame-retardant PP, which is extruded by twin-screw The temperature control of the machine is shown in Table 2.

[0019] Wherein, the PP is copolymerized PP (commercially available), and the melt index is 15-35g / 10min. The flame retardant is a phosphate ester flame retardant (commercially available). The toughening agent is POE (commercially available). The flame retardant synergist is a silicon-containing flame retardant synergist (see paper: a kind of application of a silicon-containing flame retardant synergist in polycarbonate, Hu Zhi, etc., China Flame Retardant Academic Annual Conference, 2009, or other literature available). The compatibilizer is maleic anhydride grafted polypropylene (commercially available). The anti-...

Abstract

The invention discloses super-tough flame-retardant PP and a preparation method thereof. The super-tough flame-retardant PP is prepared by mixing, by weight percentage, 40-60% of PP, 5-20% of flame retardant, 10-20% of toughening agent, 10-20% of flame retardant synergist, 2-10% of compatibilizer and 0.1-1% of anti-oxygen and anti-copper agent. The super-tough flame-retardant PP can replace flame-retardant ABS and flame-retardant PC to be applied to the field of sockets and extension sockets and is high in impact strength, high in heat resistance, high in flame retardance, high in electric insulation performance and the like.

Description

technical field [0001] The invention relates to the technical field of polymer production, in particular to a super-tough flame-retardant PP and a preparation method thereof. Background technique [0002] The quality of wall switch sockets and extension cord sockets determines their safety, and also directly affects the safety of household electricity use. Inferior wall switch sockets and extension cord sockets often emit sparks during use, which may cause electric shock and fire. Therefore, quality is very important. To look at quality, first of all, it depends on what kind of material it is made of. Like the shells of some big brand wall switch sockets and extension cord sockets, they are strong and reliable, and have certain flame retardancy and high temperature resistance. , impact resistance and other performance materials. [0003] The material requirements for switch sockets and extension cord sockets are: high strength, high toughness, high heat resistance, high fl...
