Abstract
The invention relates to an organic polymer composite material, in particular to halogen-free flame retardant environmental-protection high temperature nylon and a manufacture process of the halogen-free flame retardant environmental-protection high temperature nylon. The halogen-free flame retardant environmental-protection high temperature nylon is composed of the following components in percentage by weight: 45-80% of high temperature nylon, 5-20% of halogen-free flame retardant masterbatch, 1-3% of high temperature resisting black masterbatch, 10-45% of halogen-free alkali-free glass fiber and 0.3-5.5% of other auxiliaries. A performance of the halogen-free flame retardant environmental-protection high temperature nylon is similar to that of imported import materials, price of the halogen-free flame retardant environmental-protection high temperature nylon is only one third to a half of that of the imported import materials, and moreover, the halogen-free flame retardant environmental-protection high temperature nylon is convenient to produce and purchase, a situation that developed countries dominate the market exclusively is changed, a situation that sale price keeps up is changed, and competitive capacity is comprehensively improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free flameproof and strengthen high-temperature nylon and manufacture craft thereof.
Background technology
At present, the RoHS rules impel industry when the enterprising trip link actuator surface mounting of printed circuit board (PCB), employing meets the weldprocedure of unleaded regulation, thus higher heatproof and environmental requirement are proposed material, simultaneously, the differentiation design of various industry and civilian product has also proposed to tolerate the more still requirement of high safety of harsh and unforgiving environments to material, and will meet simultaneously various environmental protection instructions regulations.
The invention of this special type composite material is arisen at the historic moment under this background just, this material can anti-200 ℃ continuous high temperature, and can also keep good dimensional stability, and have good ductility and low warpage, nearly all size is different, strict Application Areas can both be used.Excellent long-term and short term thermal performance can be born the high temperature that infrared (IR) reflow ovens of using in the pb-free solder process produces.This product fully meets European Union's " waste and old electric electric installation " (WEEE) and " objectionable impurities limits the use of instruction " (RoHS) rules and other environmental regulations.Compare the traditional material that uses brominated additives, this product has high-end machinery and electric property more, also have simultaneously the characteristics such as easy processing, good looking appearance and laser marking, and the electrical characteristic of the chemical resistant properties excellent in dimensional stability of identical intensity and key brilliance are provided under wet environment.Compare with traditional nylon 6,66 or 46, its water regain is few 70%, and the interior coefficient of expansion is low, with metal species seemingly.
Halogen-free flame-retardance and low smoke performance are rolled into one in the invention of this special type composite material, meet
Summary of the invention
The object of the invention is to effectively overcome the defective of existing nylon, provide that a kind of physical strength is high, flame retardant properties good, and the cheap halogen-free antiflaming enhanced green high temperature nylon of the prices of raw and semifnished materials.
Technical scheme provided by the invention is as follows: high-temperature nylon: 45-80%, halogen-free flame-retardant master batch: 5-20%, high temperature resistant black masterbatch: 1-3%; Halogen alkali-free glass fiber: 10-45%; Other auxiliary agents: 0.3-5.5;
Halogen-free antiflaming enhanced green high temperature nylon material preparation method of the present invention, comprise the steps: first with high-temperature nylon, halogen-free flame-retardant master batch, high temperature resistant black masterbatch, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, in the screw combinations situation that medium tenacity is sheared, add Halogen alkali-free glass fiber by the side through twin screw extruder again and carry out mixing extrusion; Employing water cooling bracing pelletizing then screening and dewatering processing makes the halogen-free antiflaming enhanced green high temperature nylon material.
Halogen-free antiflaming enhanced green high temperature nylon material preparation control method key point of the present invention is as follows: the heat-resistant fireproof master batch can use after water ratio is lower than 0.4 in 80 degree oven dry, thoroughly clear up first machine before producing and guarantee can not contain other kind plastics, add the Halogen alkali-free glass fiber by the side and carry out mixing extrusion; There is the uncompacted product of hole must isolate and to adopt; Must carry out screening and dewatering and process, timely waterproof packing sealing when the finished product water ratio is lower than 0.5%.
The present invention has effectively overcome the defective of existing nylon, has the following advantages:
A kind of halogen-free antiflaming enhanced green high temperature nylon of the present invention, performance and import same type of material are similar, price but only is equivalent to the same type of material 1/3rd of import between half, and production procurement is convenient, having changed enterprise of developed country monopolizes the market, the situation that selling price is high, comprehensive like this competitive power that improved.
Embodiment
Below be the most preferred embodiment of halogen-free antiflaming enhanced green 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 antiflaming enhanced green high temperature nylon raw material is provided, and is made of by weight high-temperature nylon (semi-aromatic nylon PPA) following composition: 53%, and the halogen-free flame-retardant master batch of oven dry: 12%, carrier free black masterbatch: 1.5%; Halogen alkali-free glass fiber: 33%; Other auxiliary agents: 0.5;
First with the halogen-free flame-retardant master batch, high temperature resistant black masterbatch, other auxiliary agents of high-temperature nylon (semi-aromatic nylon PPA), oven dry 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, and medium tenacity is sheared; Add the Halogen alkali-free glass fiber by the side and carry out mixing extrusion; Adopt water
