Abstract
The invention discloses a high-elongation at break injection molding-level modified nylon 6 material which consists of the following components in percentage by weight: 49.5-90% of nylon 6, 3-35% of nylon modifier, 1-35% of compatibilizer, 0.3-1.5% of antioxidant and 0.3-5.5% of other auxiliaries. The high-elongation at break injection molding-level modified nylon 6 material disclosed by the invention can tolerate the low temperature of -40 DEG C, 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 high elongation at tear injection grade modified nylon-6 material.The invention still further relates to the method for making this high elongation at tear injection grade modified nylon-6 material.
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 elongation at break 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 to keep under the original tensile strength of nylon 6 material and the temperature tolerance prerequisite, possesses higher elongation at break characteristic, and can under extremely low temperature, still possess this feature, in the market, extrusion grade 6 materials possess certain elongation at break, but still are not very high, and the nylon 6 material of injection grade is just lower.
Summary of the invention
The object of the invention is to, a kind of environmental protection high elongation at tear injection grade modified nylon-6 material that can tolerate subzero 40 degree low temperature is provided.
Technical scheme provided by the invention is as follows: a kind of environmental protection high elongation at tear injection grade modified nylon-6 material is made of nylon 6:49.5-90%, modified nylon agent: 3-35% by weight following composition; Expanding material: 1-35%, antioxidant: 0.3-1.5%; Other auxiliary agents: 0.3-5.5%.
The preparation method of environmental protection high elongation at tear injection grade modified nylon-6 material of the present invention; 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 some strength is sheared, water cooling bracing pelletizing or underwater cutpellet make environmental protection high elongation at tear injection grade modified nylon-6 material through screening and dewatering again.
The advantage of environmental protection high elongation at tear injection grade modified nylon-6 material of the present invention is: can tolerate subzero 40 degree low temperature, 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 environmental protection high elongation at tear injection grade modified nylon-6 material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of environmental protection high elongation at tear injection grade modified nylon-6 material is provided, and is made of by weight nylon 6:83.5% following composition; Modified nylon agent: 12%; Expanding material: 3.0%, antioxidant: 1.0%; Other auxiliary agents: 0.5%.
First with nylon 6 oven dry, then with modified nylon agent, 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 higher-strength is sheared; Adopt water cooling bracing pelletizing mode, namely make environmental protection high elongation at tear injection grade modified nylon-6 material 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.
