Abstract
The invention relates to an environmentally-friendly semitransparent cold-resistant nylon 6 which comprises the following components in proportion by weight: 49.5-90% of nylon 6, 3-35% of nylon freezing agents, 3-35% of clarifier, 0.3-1.5% of antioxidant and 0.3-5.5% of other adjuvant. The environmentally-friendly semitransparent cold-resistant nylon 6 can resist a low temperature of 40 DEG C below zero, and the impact strength of a notch of a cantilever beam is much higher than that of a common nylon 6. Moreover, the environmentally-friendly semitransparent cold-resistant nylon 6 is convenient to produce and purchase, and thus the competitiveness is enhanced greatly.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to the translucent cold-resistant nylon 6 of a kind of environmental protection, the invention still further relates to the method for making translucent cold-resistant nylon 6 raw 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.The employed nylon 6 material in many places is arranged, need under the original associated advantages prerequisite of maintenance nylon 6 material, possess certain toughness and grease resistance characteristic, and can under extremely low temperature, still possess excellent toughness.Simultaneously, nylon 6 material itself possesses translucent characteristics, but often when traditional toughened cold-resistant modification, has become opaque oyster white, has so just limited application.At present, generally speaking, produce possess translucent and good toughness simultaneously, low temperature resistant, intensity good, the material of excellent wear resistance or the like advantage, what often adopt is special materials such as Ni Long11, nylon 12, NYLON610, nylon 1010, and these materials only have only a few major company to produce, the buying trouble, and price is very high; Fusing point, the temperature tolerance of these materials all are starkly lower than nylon 6 simultaneously, and expensive material cost has promptly been used in some field, and effect still is barely satisfactory.
Summary of the invention
The objective of the invention is to, provide a kind of environmental protection translucent cold-resistant nylon 6, can tolerate subzero 40 degree low temperature, the socle girder notched Izod impact strength is more high than common nylon 6, and production procurement is convenient, greatly improves the competitiveness like this.
Technical scheme provided by the invention is as follows: nylon 6:49.5-90%; Nylon cold-resistant agent: 3-35%; Transparent base: 3-35%; Antioxidant: 0.3-1.5%; Other auxiliary agents: 0.3-5.5%.
The preparation method of the translucent cold-resistant nylon 6 of environmental protection of the present invention, 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 the translucent cold-resistant nylon 6 material of environmental protection through screening and dewatering again.
The beneficial effect of the translucent cold-resistant nylon 6 of environmental protection of the present invention is: can tolerate subzero 40 degree low temperature, the socle girder notched Izod impact strength is more high than common nylon 6, and production procurement is convenient, greatly improves the competitiveness like this.
Embodiment
Below be the most preferred embodiment of the translucent cold-resistant nylon 6 of environmental protection of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, provides a kind of environmental protection translucent cold-resistant nylon 6, forms nylon 6:78.5% by weight by following composition; Nylon cold-resistant agent: 15%; Transparent base: 5%; Antioxidant: 1.0%; Other auxiliary agents: 0.5%.
Earlier with nylon 6 oven dry, then with nylon cold-resistant agent, transparent base, 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 the translucent cold-resistant nylon 6 material 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.
