Abstract
The invention relates to an organic polymer composite material, in particular to a manufacture process of low-smoke inflaming retarding polycarbonate. The low-smoke inflaming retarding polycarbonate is composed of the following components in percentage by weight: 47.5-96% of polycarbonate, 1-35% of phosphorus nitrogen composite halogen-free fire retardant, 1.0-3.0% of antismoke agent, 0.1-2.0% of antioxygen, 0.1-2.0% of lubricating agent and 1.3-5.5% of other auxiliaries. According to the low-smoke inflaming retarding polycarbonate and the manufacture process disclosed by the invention, the low-smoke inflaming retarding polycarbonate is environment-friendly, free of halogen and good in comprehensive mechanical behavior, effectively reduces strong black smoke produced during burning of the polycarbonate, is convenient to produce and purchase, and simultaneously meets all environment-friendly requirements, and product competitiveness is comprehensively improved.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of low-smoke non-halogen flame-retardant polycarbonate manufacture craft.
Background technology
Polycarbonate is a kind of unbodied, the nontoxic transparent thermoplastic polymer of tasteless odorless, and it has the over-all propertieies, particularly tough height such as mechanical and hot and electric, and creep is little, and product size is stable, has good electrical properties in high temperatures.Polycarbonate is widely used in all fields of national economy aspect mechano-electronic electrical lighting building safety and the medicine equipment as a kind of engineering plastics of excellent combination property.Adopt the low-smoke non-halogen flame-retardant polycarbonate material, can significantly improve its range of application, can substitute timber and metal or other materials in a lot of fields and use.And Europe/Japan etc. developed country has started all restrictions of foreign imported product for various reasons at present, has set up a series of barrier, wherein, to the material Halogen-free requirement of product, is exactly one of them.Therefore cause the more export enterprise of China is seriously perplexed.And seen in the market, perhaps can not guarantee not halogen-containingly to cause environmental protection limited, or expensive and dependency is strong, or mechanical property is excellent not, etc. shortcoming.The strong black smoke that produces when especially effectively reducing the polycarbonate burning, having had not yet to see document relates to, and the safety that smog causes and environmental issue, more and more improved at present the attention degree to it, but because technical development problem, reduce so that many times have to or abandon requirement to smog, or have to use other material instead and sacrifice the requirement of some other aspect.The present invention produces in order effectively to overcome this technological deficiency.
Summary of the invention
The object of the invention is to overcome the defective of prior art, provide a kind of comprehensive mechanical performance good, and not halogen-containing low-smoke non-halogen flame-retardant polycarbonate raw material.
Technical scheme provided by the invention is as follows: a kind of low-smoke non-halogen flame-retardant polycarbonate of the present invention is made of polycarbonate: 47.5-96% by weight following composition; 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 ‰
Low-smoke non-halogen flame-retardant polycarbonate of the present invention Production Flow Chart is: first polycarbonate is dried with 120 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 the parallel equidirectional two-screw forcing machine in the screw combinations situation that medium tenacity is sheared, keeping under the good vacuum state, with low screw speed mixing extrusion, the water cooling bracing pelletizing makes Di Yan Wu Tooth flame retardant polycarbonate material through screening and dewatering.
The present invention has effectively overcome the defective of prior art, has the following advantages:
A kind of low-smoke non-halogen flame-retardant polycarbonate of the present invention and manufacture craft thereof, environment friendly non-halogen, it is good that comprehensive mechanical performance keeps, and the strong black smoke that produces when effectively reducing the polycarbonate burning, production procurement is convenient, also meet simultaneously all environmental requirements, comprehensive like this product competitiveness that improved.
Embodiment
Below be the most preferred embodiment of low-smoke non-halogen flame-retardant polycarbonate raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of low-smoke non-halogen flame-retardant polycarbonate is provided, and is made of by weight polycarbonate following composition: 90.0%, and phosphorus nitrogen composite halogen-free fire retardant: 5%; Smoke suppressor: 2.2%; Oxidation inhibitor: 1.0%, lubricant: 0.3%; Other auxiliary agents: 1.5%.
First polycarbonate was dried 4 hours with 120 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 substantially even, do not have obvious agglomerate or gather, and then in time through the parallel equidirectional two-screw forcing machine in the screw combinations situation that medium tenacity is sheared, twin screw extruder uses 36 length-to-diameter ratios, keeping under the good vacuum state, with low screw speed mixing extrusion, the water cooling bracing pelletizing makes the low-smoke non-halogen flame-retardant polycarbonate material through screening and dewatering.
