Abstract
The invention relates to an environment-friendly low-smoke halogen-free flame-retardant nylon 6 material which comprises the following components in percentage by weight: 57.5-96% of nylon, 1-35% of phosphorus-nitrogen composite halogen-free flame retardant, 1.0-3.0% of smoke suppressor, 0.1-2.0% of antioxidant, 0.1-2.0% of lubricant and 1.3-5.5% of other assistants. The environment-friendly low-smoke halogen-free flame-retardant nylon 6 material has the advantages of favorable comprehensive mechanical properties, no halogen, low smoke, beautiful product appearance, and convenient production and purchase, and conforms to all requirements for environmental protection, thereby comprehensively enhancing the competitive power of the product.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of environmental protection low-smoke non-halogen flame-retardant nylon 6 material.The invention still further relates to the method for making this environmental protection low-smoke non-halogen flame-retardant nylon 6 material.
Background technology
Along with social development, people are more and more higher to the environmental requirement of articles for daily use, and security requirement is also more and more higher.Halogen is more and more conditions that are required recent years; Simultaneously, the fire protection requirement of electronic apparatus or the like articles for daily use is also more and more paid attention to by human consumer and manufacturer.Show that according to the ASSOCIATE STATISTICS data tragedy incident that causes owing to the smog reason has occupied total death toll more than 1/3rd in fire.At this present situation, even we have carried out Halogen, fire-retardant fireproof also only produce extremely low smog simultaneously in passive burning nylon 6 material R﹠D work, possessing These characteristics simultaneously, still keep other advantages of nylon 6 material, and had good injection molding processing characteristics and good cost competitive edge.
Summary of the invention
The objective of the invention is to, a kind of environmental protection low-smoke non-halogen flame-retardant nylon 6 material is provided, comprehensive mechanical performance is good, not halogen-containing, low cigarette, product appearance is attractive in appearance, and production procurement is convenient, also meets all environmental requirements, comprehensive like this product competitiveness that improved simultaneously.
Technical scheme provided by the invention is as follows: nylon 6:57.5-96%; Phosphorus nitrogen composite halogen-free fire retardant: 1-35%; Smoke suppressor: 1.0-3.0%; Oxidation inhibitor: 0.1-2.0%; Lubricant: 0.1-2.0%; Other auxiliary agents: 1.3-5.5%.
The preparation method of environmental protection low-smoke non-halogen flame-retardant nylon 6 material of the present invention, comprise the steps: earlier nylon 6 slice to be dried with 90 degree, then with oxidation inhibitor, phosphorus nitrogen composite halogen-free fire retardant, smoke suppressor, lubricant, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, after more in time through parallel parallel dual-screw extruding machine under the screw combinations situation that medium tenacity is sheared, keeping under the good vacuum state, mixing extruding, the pelletizing of water-cooled tie rod makes environmental protection low-smoke non-halogen flame-retardant nylon 6 material through screening and dewatering.
Environmental protection low-smoke non-halogen flame-retardant nylon 6 material comprehensive mechanical performance of the present invention is good, not halogen-containing, low cigarette, and product appearance is attractive in appearance, and production procurement is convenient, also meets all environmental requirements, comprehensive like this product competitiveness that improved simultaneously.
Embodiment
Below be the embodiment of environmental protection low-smoke non-halogen flame-retardant 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 low-smoke non-halogen flame-retardant nylon 6 material is provided, and forms nylon 6 slice by weight by following composition: 87.0%, and phosphorus nitrogen composite halogen-free fire retardant: 8%; Smoke suppressor: 2.2%; Oxidation inhibitor: 1.0%, lubricant: 0.3%; Other auxiliary agents: 1.5%.
Earlier nylon 6 slice was dried 4 hours with 90 degree, then with oxidation inhibitor, phosphorus nitrogen composite halogen-free fire retardant, smoke suppressor, lubricant, other auxiliary agents proportionally after the weighing in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, stainless steel, paddle should with the barrel gap less than 0.5 centimetre, the supplementary material mixed effect should visual various particles and powder even substantially, do not have obvious agglomerate or gather, and then in time through parallel parallel dual-screw extruding machine under the screw combinations situation that medium tenacity is sheared, twin screw extruder uses 36 length-to-diameter ratios, keeping under the good vacuum state, mixing extruding, the pelletizing of water-cooled tie rod makes environmental protection low-smoke non-halogen flame-retardant 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 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.
