Abstract
The invention relates to a process of a green environmental-protection flexible nylon 6 material. The green environmental-protection flexible nylon 6 material is composed of the following components in percentage by weight: 49.5-90% of nylon 6, 3-35% of nylon softener, 3-35% of bulking agent, 0.3-1.5% of antioxidant and 0.3-5.5% of other auxiliaries. The green environmental-protection flexible nylon 6 material can resist to a low temperature of -40 DEG C, cantilever notch impact strength is about ten times higher than that of common nylon 6, and moreover, the green environmental-protection flexible nylon 6 material is convenient to produce and purchase, raw and auxiliary materials and production equipment are all made in China, and competitive capacity is greatly improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of environmental protection flexible nylon 6 material technologies.The invention still further relates to and make this environmental protection flexible nylon 6 material technologies.
Background technology
Nylon 6 is polyamide resins, 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 shock strength of pure nylon 6 is lower, and this shortcoming is more outstanding than low ambient temperature the time.Film and the employed nylon 6 material of tubing that many places are arranged need under the maintenance original tensile strength of nylon 6 material and temperature tolerance prerequisite, possess certain flexibility and grease resistance characteristic, and can still possess excellent toughness under extremely low temperature.
In the market, the related products price of external major company is very high, and there is a certain advantage of having sacrificed nylon 6 itself in the product of domestic manufacturer, or because technique or technology not fully cause product with stable quality control bad, can not scale production use.
The present technique invention produces in order effectively to overcome this situation.
Summary of the invention
The object of the invention is to, a kind of environmental protection flexible nylon 6 materials that resist cold are provided, can tolerate subzero 40 degree low temperature, the socle girder notched Izod impact strength exceeds about ten times than common nylon 6, and production procurement is convenient.
Technical scheme provided by the invention is as follows: nylon 6:49.5-90%; Nylon softener: 3-35%; Expanding material: 3-35%; Antioxidant: 0.3-1.5%; Other auxiliary agents: 0.3-5.5%;
The environmental protection of the present invention flexible nylon 6 material preparation methods that resist cold, comprise the steps: first with nylon 6 oven dry, then with all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, through cord wood parallel equidirectional two-screw forcing machine mixing extrusion in the screw combinations situation that medium tenacity is sheared, the water cooling bracing pelletizing makes cold-resistant flexible nylon 6 materials of environmental protection through screening and dewatering again.
Environmental protection of the present invention flexible nylon 6 materials that resist cold, can tolerate subzero 40 degree low temperature, the socle girder notched Izod impact strength exceeds about ten times than common nylon 6, and 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 cold-resistant flexible nylon 6 materials of environmental protection of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of environmental protection flexible nylon 6 materials that resist cold are provided, and is made of by weight nylon 6:78.5% following composition; Nylon softener: 12%; Expanding material: 8%; Antioxidant: 1.0%; Other auxiliary agents: 0.5%.
First with nylon 6 oven dry, then with nylon softener, expanding material, antioxidant, 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, liquid substantially even, do not have obvious agglomerate or gather; Twin screw extruder uses 40 length-to-diameter ratios, and medium tenacity is sheared; Adopt water cooling bracing pelletizing mode (or underwater cutpellet mode), namely make cold-resistant flexible nylon 6 materials of environmental protection 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.
Claims (2)
1. environmental protection flexible nylon 6 material technologies is characterized in that, are made of by weight nylon 6:49.5-90% following composition; Nylon softener: 3-35%; Expanding material: 3-35%; Antioxidant: 0.3-1.5%; Other auxiliary agents: 0.3-5.5%.
2. environmental protection flexible nylon 6 material technologies; it is characterized in that; comprise the steps: first with nylon 6 oven dry; then with all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes; again through cord wood parallel equidirectional two-screw forcing machine mixing extrusion in the screw combinations situation that medium tenacity is sheared; water cooling bracing pelletizing or underwater cutpellet make cold-resistant flexible nylon 6 materials of environmental protection through screening and dewatering.
