Abstract
The invention relates to a green, environmentally-friendly, cold-resistant and flexible nylon 6 material, which consists of the following components in percentage by weight: 49.5 to 90 percent of nylon6, 3 to 35 percent of nylon softener, 3 to 35 percent of bulking agent, 0.3 to 1.5 percent of antioxygen and 0.3 to 5.5 percent of other additive. The green, environmentally-friendly, cold-resistant and flexible nylon 6 material of the invention can tolerate the low temperature of 40 DEG C below zero, has a cantilever beam gap impact strength which is about 10 times higher than that of the common nylon 6. In addition, the production and purchase are convenient, and raw and auxiliary materials and production equipment are China-made, so the competitiveness is greatly improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to cold-resistant flexible nylon 6 materials of a kind of environmental protection.The invention still further relates to the method for making cold-resistant flexible nylon 6 materials of this environmental protection.
Background technology
Nylon 6 is polyamide resins, 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 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 possess certain flexibility and grease resistance characteristic, and can still possess excellent toughness under extremely low temperature under maintenance original tensile strength of nylon 6 material and temperature tolerance prerequisite.
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 technology or technology fully cause product with stable quality control bad inadequately, can not scale production use.
The present technique invention produces in order effectively to overcome this situation.
Summary of the invention
The objective 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%;
Environmental protection of the present invention flexible nylon 6 preparation methods that resist cold, comprise the steps: earlier with nylon 6 oven dry, then with all auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, through the parallel parallel dual-screw extruding machine of cord wood mixing extruding under the screw combinations situation that medium tenacity is sheared, the pelletizing of water-cooled tie rod 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 homemade, 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, by following composition by weight forming nylon 6:78.5%; Nylon softener: 12%; Expanding material: 8%; Antioxidant: 1.0%; Other auxiliary agents: 0.5%.
Earlier 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 even substantially, do not have obvious agglomerate or gather; Twin screw extruder uses 40 length-to-diameter ratios, and medium tenacity is sheared; Adopt water-cooled tie rod pelletizing mode (or underwater cutpellet mode), promptly 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 thereto; 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.
