Abstract
The invention relates to a manufacturing process of a green environment-friendly semitransparent nylon 66 material. The green environment-friendly semitransparent nylon 66 material is composed of the following components in percentage by weight: 49.5-90% of nylon 66, 3-35% of nylon anti-freezing agent, 3-35% of clarifier, 0.3-1.5% of antioxidant and 0.3-5.5% of other assistants. According to the invention, the green environment-friendly semitransparent anti-freezing nylon 66 material can resist a low temperature of minus 40 degrees; the cantilever notch impact strength is much higher in comparison with the common nylon 66; and both the production and the procurement are convenient. Thus, the competitive power is greatly improved.
Description
Technical field
1, the present invention relates to a kind of organic polymer composite, more particularly, relate to the translucent nylon 66 material manufacture craft of a kind of environmental protection.The invention still further relates to the method for making this environmental protection semitransparent cold-resistant nylon 66 materials.
Background technology
2, nylon 66 is to use at present one of maximum several engineering plastics, and his fusing point is higher, has good physical and mechanical property and wear resistance and self lubricity, and these Comprehensive Characteristics are that other plastics are not available.But the shock strength of pure nylon 66 is lower, and this shortcoming is more outstanding than low ambient temperature the time.The employed nylon 66 material in many places is arranged, need under the original associated advantages prerequisite of maintenance nylon 66 material, possess certain toughness and grease resistance characteristic, and can under extremely low temperature, still possess excellent toughness.Simultaneously, nylon 66 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 simultaneously translucent and good toughness, low temperature resistant, intensity good, the material of excellent wear resistance etc. advantage, what often adopt is the special materials such as （Fen Mo/Ke Li） Nylon11 in powder/granular form, 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 66 simultaneously, and expensive material cost, effect or barely satisfactory have namely been used in some field.
Summary of the invention
3, the object of the invention is to, provide a kind of and can tolerate subzero 40 degree low temperature, environmental protection semitransparent cold-resistant nylon 66 materials that the socle girder notched Izod impact strength is more high than common nylon 66.
4, technical scheme provided by the invention is as follows: nylon 66:49.5-90%, nylon cold-resistant agent: 3-35%; Transparent base: 2-35%, antioxidant: 0.3-1.5%; Other auxiliary agents: 0.3-5.5%;
5, environmental protection semitransparent cold-resistant nylon 66 material preparation methods of the present invention, comprise the steps: first with nylon 66 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 environmental protection semitransparent cold-resistant nylon 66 materials through screening and dewatering again.
6, environmental protection semitransparent cold-resistant nylon 66 materials of the present invention can tolerate subzero 40 degree low temperature, and the socle girder notched Izod impact strength is more high than common nylon 66, and production procurement is convenient, greatly improves the competitiveness like this.
Embodiment
7, be the most preferred embodiment of environmental protection semitransparent cold-resistant nylon 66 materials of the present invention below, therefore do not limit protection scope of the present invention.
8, embodiment one, and a kind of environmental protection semitransparent cold-resistant nylon 66 materials are provided, and forms by weight nylon 66:81.5% by following composition; Nylon cold-resistant agent: 12%; Transparent base: 5%, antioxidant: 1.0%; Other auxiliary agents: 0.5%.
9, first with nylon 66 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 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 environmental protection semitransparent cold-resistant nylon 66 materials through screening and dewatering.
10, 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. the translucent nylon 66 material manufacture craft of environmental protection is characterized in that, is made of by weight nylon 66:49.5-90%, nylon cold-resistant agent: 3-35% following composition; Transparent base: 3-35%, antioxidant: 0.3-1.5%; Other auxiliary agents: 0.3-5.5%.
2. translucent nylon 66 material manufacture craft of environmental protection; it is characterized in that; comprise the steps: first with nylon 66 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 environmental protection semitransparent cold-resistant nylon 66 materials through screening and dewatering.
