Abstract
The invention relates to an organic polymer composite material, in particular to halogen-free anti-buckling deformation reinforced nylon 6 and a preparation method thereof. The halogen free anti-buckling deformation reinforced nylon 6 comprises the following components in percentage by weight: nylon 6 45-70, halogen-free and alkali-free glass fibers 1-35, halogen-free glass microspheres 1-40, flexibilizer 1-5, coupling agent 0.1-0.4 and other assistants 0.1-5.5. The halogen-free anti-buckling deformation reinforced nylon 6 and the manufacturing process thereof are halogen-free and environmentally friendly, have excellent comprehensive mechanical properties and a characteristic of excellent anti-buckling deformation performance, are more suitable to be used for producing tightly assembled parts such as masks/shells and other product frameworks, and are convenient in production and purchase. Thus, the comprehensive competitive power of the product is fully 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 preparation method thereof.
Background technology
Nylon 6 is to use one of maximum several engineering plastics at present, his amide group has polarity, in his structure, has well-set hydrogen bond, make 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 big, and shock strength is on the low side before the suction, suction back rigidity declines to a great extent again, shortcoming such as size instability simultaneously, thus limited the application of nylon 6, and then dwindled downstream industry design engineer's selection leeway again.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 glass fiber reinforced nylon 6 exactly.And Europe/Japan or the like 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 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, produces big internal stress easily when moulding, thereby causes the final product buckling deformation.
Existing Reinforced Nylon 6 materials of producing anti-warpage are to adopt talcum powder to play anti-warping effect in the existing market, and it is low to have intensity, and anti-warpage effect is insufficient, influences 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 objective of the invention is to overcome the defective of prior art, a kind of halogen-free anti-buckling deformation reinforced nylon dragon 6 raw materials that increased the good feature of anti-buckling deformation on comprehensive mechanical performance keeps good basis are provided.
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, form nylon 6:45-70%, Halogen alkali-free glass fiber: 1-35% by weight by 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: earlier 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 the Halogen alkali-free glass fiber slow speed of revolution mixing extrude by the side through twin screw extruder under the screw combinations situation that medium tenacity is sheared again, the pelletizing of water-cooled tie rod 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 having increased the good feature of anti-buckling deformation on the good basis at comprehensive mechanical performance, face shield/shell and the product skeleton class product that is used to produce 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 forms nylon 6:48%, the high pigment black masterbatch of nylon 6 carriers: 1.5% by weight by following composition; Halogen alkali-free glass fiber: 23%; Halogen glass microballon: 22%: toughner: 3%; Coupling agent: 0.3%; Other auxiliary agents: 2.2%;
Earlier 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 even substantially, 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-cooled tie rod pelletizing mode, promptly make halogen-free anti-buckling deformation reinforced nylon dragon 6 materials through screening and dewatering.
