Abstract
The invention relates to a flame-retardant whisker-enhanced polypropylene alloy material, belonging to the technical field of macromolecular materials. The alloy material is prepared from the following raw materials in parts by weight: 44.2-49.5 parts of polypropylene resin, 7.2-13.1 parts of rubber, 3-5 parts of nylon resin, 6-9 parts of compatibilizer, 11-19 parts of flame retardant, 5-8 parts of whisker enhancer, 0.4-0.8 part of antioxidant, 9-15 parts of glass fiber and 1.2-2 parts of carbon black. The flame-retardant whisker-enhanced polypropylene alloy material has the advantages that the bending strength is greater than 73-92 MPa, the izod notched impact strength is 14.5-18.3 kj/m<2>, the thermal deformation temperature is 155-170 DEG C, and the flame retardance V-0 is UL-94-V-0-1.6 mm, so that the use field of the flame-retardant whisker-enhanced polypropylene alloy material can be expanded.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to the polypropylene alloy material that a kind of fire-retardant whisker strengthens.
Background technology
Because polypropylene has good electrical performance characteristics, low temperature tolerance characteristics, chemical stability and workability etc., thereby extensively is used in automobile, building materials, textile equipment, food product pack etc.Because polypropylene is a kind of combustible material, easily forms wire drawing during burning and produce a large amount of molten drops, thereby limited to a certain extent polypropylene and used widely.Hence one can see that, polypropylene material carried out modification have positive effect.
Summary of the invention
Task of the present invention is to provide that a kind of intensity is high, heat resistance good and flame retardant effect is excellent and use the polypropylene alloy material that the fire-retardant whisker of expanding use range strengthens.
Task of the present invention is finished like this, the polypropylene alloy material that a kind of fire-retardant whisker strengthens, and its raw material by following parts by weight forms:

In another embodiment of the present invention, described rubber is paracril
In yet another embodiment of the present invention, described nylon resin is that fusing point is at the NYLON610 resin more than 220 ℃.
In another embodiment of the present invention, described compatilizer is the maleic anhydride grafted polyethylene resin.
Also have among the embodiment of the present invention, described fire retardant is TDE.
More of the present invention and among embodiment, described whisker toughener is the calcium sulfate crystal whiskers of length 150-220 micron.
In of the present invention and then embodiment, described oxidation inhibitor is tricresyl phosphite (24-di-tert-butyl-phenyl) ester.
Of the present invention again more and among embodiment, described glass fibre is the alkali free glass fibre of length 3mm.
In again of the present invention and then embodiment, described carbon black is that carbonarius is female.
