Abstract
The invention discloses a stretch-proof polypropylene composite material. The stretch-proof polypropylene composite material is prepared from, by weight, 55-58% of polypropylene, 10% of toughening agent, 5% of talcum powder, 5% of glass fiber, 20% of halogen-free flame retardant, 1-2% of coupling agent, 1% of antioxidant and 2-3% of polyethylene glycol. In addition, the sum of weight proportions of the components is 100%. The stretch-proof polypropylene composite material has higher toughness and flame retardance.
Description
Technical field
The present invention relates to matrix material preparation, particularly relate to a kind of stretch-proof polypropylene composite material.
Background technology
Polypropylene is one of five large general-purpose plastics, nontoxic, light weight, corrosion-resistant, be easy to processing, production cost is low, and comprehensive mechanical property is good, is widely used in producing and sphere of life.In recent years, it is the highest that the consumption of general-purpose plastics increases, but it belongs to inflammable material, there is potential safety hazard, therefore carries out modification to it, and it is necessary for giving its flame retardant properties.At present, prepared by the polypropylene (PP) that a lot of household appliances shell material adopts V0 level fire-retardant all successively.
Warm-air drier is all generally prepared by fire-retardant material, but in view of within these 2 years, the too many case of catching fire due to warm-air drier initiation occurs, Australia standard committee has issued new standard, a lot of more strict requirement is added to this series products, also certain requirement is had to the glowing filament performance of material, namely will by glowing filament flammability index (GWIT) test of 850 DEG C.The requirement of Australia regulator, all products not meeting these new demands, are prohibited from entering market, Australia.And the general fire-retardant PP of V0 level is not nearly all by the GWIT glowing filament flammability index test of 750 DEG C, do not meet the new standard in Australia, greatly limit its application market.
But existing high glow-wire polypropylene commercially, due to fire retardant addition large (generally wanting more than 50%), greatly reduces the mechanical property of material, particularly tensile strength is on the low side, generally only have 12MPa, show as material partially soft, be difficult to the demand meeting client.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of stretch-proof polypropylene composite material.
In order to solve the problems of the technologies described above, the invention provides a kind of stretch-proof polypropylene composite material, comprise following component and the weight proportion of each component is:
