Abstract
The invention relates to an environmental-friendly black nylon material, and belongs to the technical field of high-molecular materials. The environmental-friendly black nylon material is prepared from the following raw materials in parts by weight: 39-48 parts of nylon 66 resin, 7-12 parts of polypropylene resin, 6-9 parts of compatilizers, 0.3-0.9 part of coupling agents, 9-17 parts of fire retardants, 7-15 parts of phosphate, 0.3-0.7 parts of antioxidants, 15-26 parts of glass fibers and 2-3 parts of carbon black. The environmental-friendly black nylon material provided by the invention is tested to have the following performance indexes: the tensile strength is higher than 120-140 MPa, the bending strength is higher than 210-230 MPa, the cantilever notch impact strength is higher than 11-16 kj/m<2>, and the fire retardance achieves V-0(UL-94-1.6 mm).
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of black nylon material of environmental protection.
Background technology
Nylon is the broad-spectrum engineering plastics of a class, because there are shortcomings such as low temperature brittleness is big, water-intake rate is high, poor dimensional stability in pure nylon resin, thereby has influenced the application of pure nylon resin to a certain extent.To the nylon resin modification, can improve the above-mentioned shortcoming of nylon with acrylic resin, and can bring the nylon products flexible to improve, have good practice significance.Again, the nylon products poor fire has flame retardant resistance in order to make it, often add some halogen-containing fire retardants, use TDE and antimonous oxide to do fire retardant as patent CN10153570A, although flame retardant properties is good, but discharge toxic smog during burning, influence environment.
Summary of the invention
Task of the present invention is the black nylon material that a kind of environmental protection will be provided, and it has halogen-free flameproof, high, the environment amenable characteristics of intensity.
Task of the present invention is finished like this, a kind of black nylon material of environmental protection, and its raw material by following parts by weight is formed:
In one embodiment of the invention, described Nylon 66 be fusing point more than 230 ℃ and viscosity index be 2.4 nylon resin.
In another embodiment of the present invention, described acrylic resin is a homo-polypropylene, and its molten finger is 2～6g/10min, 170 ℃ of fusing points.
In yet another embodiment of the present invention, described compatilizer is the polypropylene of maleic anhydride graft, and its percentage of grafting is 0.8%.
In another embodiment of the present invention, described coupling agent is the aminopropyl Ethoxysilane.
Also have among the embodiment of the present invention, described fire retardant is the melamine urate.
More of the present invention and among embodiment, described phosphoric acid salt is melamine pyrophosphate.
In of the present invention and then embodiment, described oxidation inhibitor is three (2,4 di-tert-butyl-phenyl) phosphorous acid ester.
Of the present invention again more and among embodiment, described glass fibre is the alkali-free short glass fiber of length 3mm.
