Abstract
The invention relates to an organic polymer composite material, in particular to a halogen-free enhanced high temperature nylon raw material. The invention also relates to a preparation method of thehalogen-free enhanced high temperature nylon. The halogen-free enhanced high temperature nylon comprises the following components in percentage by weight: 49.5-90% of high temperature nylon, namely semi-aromatic nylon PPA; 0.1-10% of heat-resisting black master batch; 10-45% of halogen-free alkali-free glass fiber; and 0.3-5.5% of lubricant and heat stabilizer. The halogen-free enhanced green hightemperature nylon raw material has similar performance to similar imported materials, but the price thereof is only from one third to a half of the price of the similar imported materials, in addition, the raw material can be easily purchased, thereby changing the conditions that foreign manufacturers dominate the market and the sale price remains high and does not fall, so that the competitiveness is overall improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen-free enhanced high temperature nylon raw material.The invention still further relates to the preparation method of this halogen-free enhanced high temperature nylon.
Background technology
At present, the application with metal in the alternative automotive industry of plastics constantly enlarges in the world, 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.
It is possible that the development that strengthens high-temperature nylon changes into the more microminiaturized and powerful of automobile.High temperature resistant nylon can bring higher heat resistance for some parts of automobile.The equally also useful high temperature resistant nylon of the engine box of new automobile and the drift stop of automobile and clutch pack replaces the trend of metal and thermosetting material.These all will strengthen the demand to this high temperature resistant nylon material, thereby drive the nylon market requirement.
This material can anti-180 ℃ continuous high temperature, and can also keep good dimensional stability.Has excellent long-term and short term thermal performance, can tolerate infrared (IR) high temperature that reflow ovens produced that uses in the pb-free solder process, has excellent physical strength, and under wet environment, provide identical intensity and toughness, remarkable chemical resistant properties, dimensional stability, excellent electrical characteristic, good surface appearance.
This series product market is substantially all captured by western developed country enterprise at present, China enterprise or can not produce, or can not stablize controlling performance, these are the problem to be solved in the present invention just.
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 objective of the invention is to effectively overcome the defective of existing nylon, a kind of physical strength height is provided, good flame resistance, and the cheap Halogen that is easy to get of the prices of raw and semifnished materials strengthens the green high temperature nylon raw material.
Technical scheme provided by the invention is as follows: a kind of Halogen strengthens green high temperature nylon, is made of high-temperature nylon (semi-aromatic nylon PPA): 49.5-90% according to weight ratio following composition; High temperature resistant black agglomerate: 0.1%-10%; Halogen alkali-free glass fiber: 10-45%; Lubricant and thermo-stabilizer: 0.3-5.5;
Halogen of the present invention strengthens the green high temperature nylon preparation methods, comprise the steps: earlier with high-temperature nylon, lubricant and thermo-stabilizer proportionally after the weighing in mixer low speed mixing 10 minutes, added in proportion by the side under the screw combinations situation that medium tenacity is sheared through twin screw extruder that the Halogen alkali-free glass fiber is mixing to be extruded, the pelletizing of water-cooled tie rod makes Halogen through screening and dewatering and strengthens the green high temperature nylon material again.
The preparation control method key point that Halogen of the present invention strengthens the green high temperature nylon material is as follows:
Thoroughly clear up machine before producing earlier and guarantee can not contain other kind plastics; There is the uncompacted product of hole must isolate and to adopt; Finished product must pass through screening and dewatering; The finished product water ratio is lower than timely waterproof packing sealing in 0.5% o'clock.
The present invention has effectively overcome the defective of existing nylon, has the following advantages:
A kind of Halogen of the present invention strengthens the green high temperature nylon raw material, 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 external producer monopolizes the market, the situation that selling price is high, comprehensive like this competitive power that improved.
Embodiment
Below be the most preferred embodiment that Halogen of the present invention strengthens the green high temperature nylon raw material, therefore do not limit protection scope of the present invention.
Embodiment one, provides a kind of Halogen to strengthen the green high temperature nylon raw material, forms high-temperature nylon (semi-aromatic nylon PPA) by weight by following composition: 65%, and high temperature resistant black agglomerate: 1.5%; Halogen alkali-free glass fiber: 33%; Lubricant and thermo-stabilizer: 0.5;
Earlier with high-temperature nylon (semi-aromatic nylon PPA), high temperature resistant black agglomerate, lubricant and thermo-stabilizer 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 even substantially, do not have obvious agglomerate or gather; Twin screw extruder uses 36 length-to-diameter ratios, and medium tenacity is sheared; The Halogen alkali-free glass fiber is added in proportion by the side; Adopt water-cooled tie rod pelletizing mode, promptly make Halogen through screening and dewatering and strengthen the green high temperature nylon material.
Claims (2)
1, a kind of halogen-free enhanced high temperature nylon is characterized in that: form high-temperature nylon (semi-aromatic nylon PPA): 49.5-90% by weight by following composition; High temperature resistant black agglomerate: 0.1%-10%; Halogen alkali-free glass fiber: 10-45%; Lubricant and thermo-stabilizer: 0.3-5.5.
2, a kind of method for preparing halogen-free enhanced high temperature nylon, it is characterized in that: comprise the steps: that finished product is through screening and dewatering, then with high-temperature nylon, lubricant and thermo-stabilizer proportionally after the weighing in mixer low speed mixing 10 minutes, under the screw combinations situation that medium tenacity is sheared, add the Halogen alkali-free glass fiber through twin screw extruder again and carry out mixing extruding by the side, the pelletizing of water-cooled tie rod makes the halogen-free antiflaming enhanced green high temperature nylon material through screening and dewatering again, and the finished product water ratio is lower than timely waterproof packing sealing in 0.3% o'clock.
