Abstract
The invention relates to an organic high polymer composite material, and more specifically relates to a halogen-free anti-buckling-deformation reinforced nylon 6 and a manufacturing process thereof. The halogen-free anti-buckling-deformation reinforced nylon 6 is composed of the following components in percentage by weight: 45-70% of nylon 6, 1-35% of halogen-free and alkali-free glass fiber, 1-40% of halogen-free glass microsphere, 1-5% of toughener, 0.1-0.4% of coupling agent and 0.1-5.5% of other assistants. According to the invention, the halogen-free anti-buckling-deformation reinforced nylon 6 and the manufacturing process thereof have the characteristics that the reinforced nylon 6 is halogen-free and environment-friendly and a good anti-buckling-deformation property is added on the basis of keeping favorable comprehensive mechanical properties, thereby being more suitable for the production of masks/shells required to be tightly assembled and molded parts such as product frameworks and the like; and both the production and the procurement are convenient. Thus, the comprehensive competitive power of the product 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 anti-buckling deformation reinforced nylon dragon 6 and manufacture craft thereof.
Background technology
Nylon 6 is to use at present one of maximum several engineering plastics, his amide group has polarity, in his structure, has well-set hydrogen bond, so that the fusing point of nylon 6 is higher, have good physical and mechanical property and wear resistance and self lubricity, these Comprehensive Characteristics are that other plastics are not available.But the heat-drawn wire of pure nylon 6 is lower, and water-absorbent is large, and shock strength is on the low side before the suction, rigidity declines to a great extent again after the suction, the shortcomings such as simultaneously size is unstable, thus limited the application of nylon 6, and then dwindled again downstream industry design engineer's selection leeway.Therefore, launched nylon 6 is carried out composite modified research.And improve the comprehensive employed the most universal the most effective method of physical and mechanical property of nylon 6 material, adopt exactly glass fiber reinforced nylon 6.And Europe/Japan etc. developed country has started all restrictions of foreign imported product for various reasons at present, has set up a series of barrier, wherein, to the material Halogen-free requirement of electric equipment products, is exactly one of them.Therefore cause the more export enterprise of China is seriously perplexed.Simultaneously, owing to glass fibre has than big L/D ratio, and nylon 6 is crystal type materials, easily produces larger internal stress when moulding, thereby causes the final product buckling deformation.
The existing reinforced nylon 6 material of producing anti-warpage is to adopt talcum powder to play anti-warping effect in the existing market, has intensity low, and anti-warpage effect is insufficient, affects product appearance gloss, the serial shortcoming that material flowability is bad.The present technique invention produces in order effectively to overcome this phenomenon.
Summary of the invention
The object of the invention is to overcome the defective of prior art, provide a kind of and keep good basis to increase halogen-free anti-buckling deformation reinforced nylon dragon 6 raw materials of the good feature of anti-buckling deformation at comprehensive mechanical performance.
Technical scheme provided by the invention is as follows: a kind of halogen-free anti-buckling deformation reinforced nylon dragon 6 of the present invention is made of nylon 6:45-70%, Halogen alkali-free glass fiber: 1-35% by weight following composition; Halogen glass microballon: 1_40%; Toughner: 1-5%; Coupling agent: 0.1-0.4%; Other auxiliary agents: 0.1-5.5%.
The preparation technology of halogen-free anti-buckling deformation reinforced nylon of the present invention dragon 6 raw materials is: first with nylon 6, Halogen glass microballon, toughner, coupling agent, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, in proportion add Halogen alkali-free glass fiber 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 halogen-free anti-buckling deformation reinforced nylon dragon 6 materials through screening and dewatering.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of halogen-free anti-buckling deformation reinforced nylon dragon 6 of the present invention and manufacture craft thereof, has halogen-free environmental, and keep good basis to increase the good feature of anti-buckling deformation at comprehensive mechanical performance, face shield/shell and product skeleton class product for the production of the need close fit preferably, and production procurement is convenient, comprehensive like this synthesized competitiveness that improves product.
Embodiment
Below be the most preferred embodiment of halogen-free anti-buckling deformation reinforced nylon dragon 6 raw materials of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of halogen-free anti-buckling deformation reinforced nylon dragon 6 is provided, and is made of by weight nylon 6:48%, the high pigment black masterbatch of nylon 6 carriers: 1.5% following composition; Halogen alkali-free glass fiber: 23%; Halogen glass microballon: 22%: toughner: 3%; Coupling agent: 0.3%; Other auxiliary agents: 2.2%;
First with nylon 6 oven dry, then the high pigment black masterbatch of nylon 6, nylon 6 carriers, Halogen glass microballon, toughner, coupling agent, other auxiliary agents after the 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, the combination of medium tenacity shear screw, and setting is not higher than 300 rev/mins rotating speed; The Halogen alkali-free glass fiber is added in proportion by the side; Adopt water cooling bracing pelletizing mode, namely make halogen-free anti-buckling deformation reinforced nylon dragon 6 materials through screening and dewatering.
