Abstract
The invention relates to an organic high-molecule composite material, more specifically relates to high-glaze flame-retardant high-temperature nylon and a manufacturing process thereof. The organic high molecule composite material is formed by the following ingredients according to parts by weight: 39.5-90% of half aroma nylon PPA (phenyl-propanolamine), 5-20% of halogen-free high-temperature resistant flame-retardant masterbatch, 2-6% of a halogen-free high temperature resistant auxiliary fire retardant, 1-30% of a halogen-free glass microballoon, 1-5% of flexibilizer, 0.1-0.4% of a coupling agent and 0.1-5.5% of other accessory ingredients. The halogen-free buckling deformation prevention high-glaze flame-retardant high-temperature nylon and the manufacturing process thereof provided by the invention have the advantages that in addition to the favorable comprehensive mechanical property and the halogen-free flame-retardant property, the nylon in the invention is also characterized by strong capability in avoiding buckling and deformation and a high-glaze and beautiful appearance, and the production and acquisition of the nylon are convenient, thereby improving competitiveness.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly relate to a kind of glazed flame-retardant high-temperature nylon and manufacture craft thereof.
Background technology
The application that at present substitutes metal in the industry with plastics in the world constantly enlarges, and scientist all over the world actively seeks new high-performance thermoplastics by various tests, also becomes enterprise and strives for more families and the important component part of extending volume growth.The development of high-temperature nylon makes this become possibility.High temperature resistant nylon can bring higher heat resistance for some parts.This material can anti-180 ℃ continuous high temperature, has excellent long-term and short term thermal performance, can tolerate the high temperature that infrared (IR) reflow ovens of using in the pb-free solder process produces, has excellent physical strength, and under wet environment, provide identical intensity and toughness, remarkable chemical resistant properties, excellent electrical characteristic.But, owing to cause easily orientation, anisotropy, when moulding, produce easily larger internal stress, thereby cause the final product buckling deformation.To have intensity low for the existing inflaming retarding high-temperature nylon material of producing anti-warpage in the existing market, and anti-warpage effect is insufficient, and product appearance gloss is good not, the serial shortcoming that material flowability is bad.The present technique invention produces in order effectively to overcome this phenomenon.
Series product of the present invention fully meet European Union's " waste and old electric electric installation " (WEEE) and " objectionable impurities limits the use of instruction " (RoHS) rules and other environmental regulations, and strict Application Areas can both be used.
Summary of the invention
The object of the invention is to effectively overcome the defective of prior art, provide a kind of gloss appearance degree high, the anti-effective halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon raw material of warpage.
Technical scheme provided by the invention is as follows: a kind of halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon raw material of the present invention is made of by weight following composition, semi-aromatic nylon PPA:39.5-90%; Halogen-free refractory fire-retardant master granule: 5-20%; Halogen-free refractory auxiliary flame retardant 2-6%; Halogen glass microballon: 1-30%; Toughner: 1-5%; Coupling agent: 0.1-0.4%; Other auxiliary agents: 0.1-5.5%0
The preparation method of halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon material of the present invention, comprise the steps: first with high-temperature nylon, Halogen glass microballon, toughner, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, in proportion add halogen-free refractory fire-retardant master granule, halogen-free refractory auxiliary flame retardant slow speed of revolution mixing extrusion by the side through twin screw extruder in the screw combinations situation that medium tenacity is sheared again, the water cooling bracing pelletizing makes the halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon material through screening and dewatering.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon of the present invention and manufacture craft thereof, keep the basis of good and halogen-free flameproof to increase the feature that anti-buckling deformation is good and the outward appearance high gloss is attractive in appearance at comprehensive mechanical performance, production procurement is convenient, has improved like this competitive power.
Embodiment
Below be the most preferred embodiment of halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon raw material is provided, and is made of by weight semi-aromatic nylon PPA:57%, high temperature resistant black masterbatch: 1.5% following composition; Halogen-free refractory fire-retardant master granule: 8%; Halogen-free refractory auxiliary flame retardant: 3%; Halogen glass microballon: 25%: toughner: 3%; Coupling agent: 0.3%; Other auxiliary agents: 2.2%;
First with semi-aromatic nylon PPA, high temperature resistant black masterbatch, Halogen glass microballon, toughner, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, the combination of medium tenacity shear screw, and setting is not higher than 200 rev/mins rotating speed; Halogen-free refractory fire-retardant master granule, halogen-free refractory auxiliary flame retardant are added in proportion by the side; Adopt water cooling bracing pelletizing mode, namely make the halogen-free buckling deformation prevention glazed flame-retardant high-temperature nylon material through screening and dewatering.
