Abstract
The invention relates to an organic polymer composite material, in particular to high-fluidity injection-level nylon 6 and a preparation process thereof. The high-fluidity injection-level nylon 6 comprises the following components in percentage by weight: 95.5-99 percent of nylon 6 slices, 0.1-0.3 percent of nucleating agent, 1.0-3.0 percent of flow modifier, 0.3-1.5 percent of antioxidant and 0.1-1.5 percent of other additives The high-fluidity injection-level nylon 6 has extremely high fluidity, easy injection demolding, releasing agent avoidance, convenient production and purchase, home-made raw and auxiliary materials and production equipment, low production cost and low raw material cost and keeps all the advantages of general nylon 6, thereby greatly improving the overall competitiveness of the product.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of high-fluidity injection-level nylon 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 social technology develop rapidly is at present maked rapid progress, and the product innovation new invention pours out, and wherein has many product innovation structures very complicated, and requires to produce rapidly, can have lower production cost can supply to marketing fast simultaneously.Like this, just require starting material to have higher flowability so that be full of mould, injection moulding fast, relative starting material and production cost are lower.Therefore, launched nylon 6 is carried out composite modified research.And at present Europe, Japanese or the like developed country have started all restrictions of foreign imported product for various reasons, have set up a series of barrier, wherein, to the material Halogen requirement of electric equipment products, are exactly one of them.Simultaneously, owing to contain many cyclophanes cyanogen in the more releasing agent, this also is the composition of strict restriction in present many environmental requirements, in order to ensure safety, reach environmental requirement, the most direct way is exactly the starting material demouldings easily itself, does not need to use releasing agent, and the present technique invention produces in order effectively to overcome the prior art defective.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of high workability is provided, the easy demoulding of injection moulding exempts to add the high-fluidity injection-level nylon 6 raw material of releasing agent.
Technical scheme provided by the invention is as follows: a kind of high-fluidity injection-level nylon 6 of the present invention, form nylon 6 slice by weight by following composition: 95.5-99%, nucleator: 0.1-0.3%; Flow ability modifying agent: 1.0-3.0%, antioxidant: 0.3-1.5%; Other auxiliary agents: 0.1-1.5%.
High-fluidity injection-level nylon 6 Production Flow Chart of the present invention is: earlier nylon 6 slice is dried, then with all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, vacuumize at the uniform velocity mixing extruding through the parallel parallel dual-screw extruding machine of cord wood under the screw combinations situation that medium tenacity is sheared again, the pelletizing of water-cooled tie rod makes the high-fluidity injection-level nylon 6 material through screening and dewatering.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of high-fluidity injection-level nylon 6 of the present invention and manufacture craft thereof, has high flowability, the easy demoulding of injection moulding, exempt to add releasing agent, all advantages that keep nylon 6 commonly used to be had simultaneously, and production procurement is convenient, and raw and auxiliary material and production unit all adopt homemade, production cost and material cost are cheap, have improved comprehensive competitive power of product so greatly.
Embodiment
Below be the most preferred embodiment of high-fluidity injection-level nylon 6 raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of high-fluidity injection-level nylon 6 is provided, and forms nylon 6 slice by weight by following composition: 96.5%; Nucleator: 0.2%; Flow ability modifying agent: 2%, antioxidant: 1.0%; Other auxiliary agents: 0.3%.
Earlier nylon 6 slice is dried, then with antioxidant, nucleator, flow ability modifying 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 even substantially, do not have obvious agglomerate or gather; Twin screw extruder uses 40 length-to-diameter ratios, and medium tenacity is sheared, and extracting vacuum keeps the screw rod uniform rotation mixing; Adopt water-cooled tie rod pelletizing mode, promptly make the high-fluidity injection-level nylon 6 material through screening and dewatering.
Claims (2)
1. a high-fluidity injection-level nylon 6 is characterized in that: form nylon 6 slice by weight by following composition: 95.5-99%, nucleator: 0.1-0.3%; Flow ability modifying agent: 1.0-3.0%, antioxidant: 0.3-1.5%; Other auxiliary agents: 0.1-1.5%.
2. method for preparing high-fluidity injection-level nylon 6, it is characterized in that: comprise the steps: earlier nylon 6 slice to be dried, then with all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, vacuumize at the uniform velocity mixing extruding through the parallel parallel dual-screw extruding machine of cord wood under the screw combinations situation that medium tenacity is sheared again, the pelletizing of water-cooled tie rod makes the high-fluidity injection-level nylon 6 material through screening and dewatering.
