Abstract
The invention discloses a thin-wall fast injection molding special nylon 6 material which consists of the following components in percentage by weight: 85.5-99% of nylon 6 slice, 0.1-0.3% of nucleating agent, 1.0-3.0% of high-speed flow modifier, 1.0-8.0% of plasticizer, 0.3-1.5% of antioxidant and 0.1-1.5% of other auxiliaries. The thin-wall fast injection molding special nylon 6 material disclosed by the invention has extremely high fluidity and maintains all advantages of common nylon 6; and moreover, the production purchasing is convenient, and the raw and auxiliary materials and the production equipment are all domestic products, thereby remarkably improving the competitiveness.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly relate to a kind of thin-walled fast injection molding special-purpose nylon 6 materials, the invention still further relates to the method for making this thin-walled fast injection molding special-purpose nylon 6 materials.
Background technology
The thin-walled fast injection molding generally all is to adopt LCP liquid crystalline resin material at present, this material have at high temperature can rapid flow characteristics, also has simultaneously fusing point height, body fire protection flame retarding etc. advantage, but its price is very high, and manufacturer is few, and waste recovery recycling difficulty is also larger.
Summary of the invention
The object of the invention is to advantageous environmental protection thin-walled fast injection molding special-purpose nylon 6 materials that a kind of high flowability are provided and keep general nylon 6 to have.
Technical scheme provided by the invention is as follows: a kind of environmental protection thin-walled fast injection molding special-purpose nylon 6 materials are made of nylon 6 slice: 85.5-99%, nucleator: 0.1-0.3% by weight following composition; Flow at high speed properties-correcting agent: 1.0-3.0%; Softening agent: 1.0-8.0%; Antioxidant: 0.3-1.5%; Other auxiliary agents: 0.1-1.5%.
Environmental protection thin-walled fast injection molding special-purpose nylon 6 material preparation methods of the present invention; comprise the steps: first nylon 6 slice to be dried; then with all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes; in the screw combinations situation that some strength is sheared, vacuumize at the uniform velocity mixing extrusion through cord wood parallel equidirectional two-screw forcing machine again; water cooling bracing pelletizing or underwater cutpellet make environmental protection thin-walled fast injection molding special-purpose nylon 6 materials through screening and dewatering.
The advantage of environmental protection thin-walled fast injection molding special-purpose nylon 6 materials of the present invention: by to the nylon 6 material modification, it is being kept on the former advantageous basis, flowability is extremely at a high speed arranged again, can produce the product of thin-walled fast injection molding in many places, even at some local LCP material that substitutes, can greatly reduce cost, production procurement is convenient, raw and auxiliary material and production unit all adopt domestic, greatly improve the competitiveness like this.
Embodiment
Below be the most preferred embodiment of environmental protection thin-walled fast injection molding special-purpose nylon 6 materials of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of environmental protection thin-walled fast injection molding special-purpose nylon 6 materials are provided, and is made of by weight nylon 6 slice following composition: 93.5%; Nucleator: 0.2%; Flow at high speed properties-correcting agent: 2.0%; Softening agent: 3.0%; Antioxidant: 1.0%; Other auxiliary agents: 0.3%.
The method of making environmental protection thin-walled fast injection molding special-purpose nylon 6 materials is: first nylon 6 slice is dried, then with antioxidant, nucleator, flow at high speed properties-correcting agent, softening 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 substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 40 length-to-diameter ratios, shears than weak intensity, and extracting vacuum keeps the screw rod uniform rotation mixing; Adopt water cooling bracing pelletizing mode, namely make environmental protection thin-walled fast injection molding special-purpose nylon 6 materials through screening and dewatering.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
