Abstract
The invention relates to a halogen flame-retardant transparent polycarbonate material which consists of the following components in percentage by weight: 47.5-96% of polycarbonate, 1-35% of bromination polycarbonate, 1.0-3.0% of transparent reagent, 0.1-2.0% of antioxidant, 0.1-2.0% of lubricant and 1.3-5.5% of other auxiliaries. The anti-stress cracking halogen flame-retardant transparent polycarbonate material provided by the invention is excellent in comprehensive mechanical performance, basically maintains the original transparency of the polycarbonate material and has beautiful appearance; and moreover, the material is convenient to produce, conforms to all environmental protection requirements and has low price, thereby comprehensively improving the product competitiveness.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of halogen anti-flaming transparent polycarbonate material that has.The invention still further relates to this method that halogen anti-flaming transparent polycarbonate material is arranged of making.
Background technology
Polycarbonate is a kind of unbodied, the nontoxic transparent thermoplastic polymer of tasteless odorless, and it has machinery and heat and electric over-all properties, particularly tough are high, 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 fire-retardant fireproof grade 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 security improves greatly.But seen in the market, or expensive and strong to external import dependency, or performance is excellent not, etc. shortcoming.Simultaneously, because the adding of fire retardant tends to seriously reduce the original transparency of material.And polycarbonate material self has an intrinsic defective, is exactly to have easily larger internal stress when injection moulding is produced, and causes the final product cracking, and condemnation factor is very high, obviously strengthens cost.
Summary of the invention
The object of the invention is to, what a kind of anti-stress cracking was provided has a halogen anti-flaming transparent polycarbonate material, and comprehensive mechanical performance is good, substantially keeps the original transparency of polycarbonate material, and product appearance is attractive in appearance, and convenient for production.
Technical scheme provided by the invention is as follows: polycarbonate: 47.5-96%; Brominated polycarbonate: 1-35%; Transparent base: 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 that halogen anti-flaming transparent polycarbonate is arranged of anti-stress cracking of the present invention, comprise the steps: first polycarbonate to be dried with 120 degree, then with oxidation inhibitor, brominated polycarbonate, transparent base, lubricant, other auxiliary agents proportionally after the weighing again in the mixer low speed mixing after 5 minutes more in time in the screw combinations situation of parallel equidirectional two-screw forcing machine in medium tenacity, keeping under the good vacuum state, with certain screw speed mixing extrusion, the water cooling bracing pelletizing has a halogen anti-flaming transparent polycarbonate material through what screening and dewatering made anti-stress cracking.
The anti-stress cracking of the present invention halogen anti-flaming transparent polycarbonate material arranged, comprehensive mechanical performance is good, the basic original transparency of polycarbonate material that keeps, product appearance is attractive in appearance, and convenient for production, simultaneously also meet all environmental requirements, low price, comprehensive like this competitive power that improves product.
Embodiment
Below be the embodiment that halogen anti-flaming transparent polycarbonate material is arranged of anti-stress cracking of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and what a kind of anti-stress cracking was provided has a halogen anti-flaming transparent polycarbonate material, is made of by weight polycarbonate following composition: 47.5-96%; Brominated polycarbonate: 1-35%; Transparent base: 1.0-3.0%; Oxidation inhibitor: 0.1-2.0%; Lubricant: 0.1-2.0%; Other auxiliary agents: 1.3-5.5%.
First polycarbonate was dried 4 hours with 120 degree, then with oxidation inhibitor, brominated polycarbonate, transparent base, lubricant, other auxiliary agents are low speed mixing 5 minutes in the mixer again after the weighing proportionally, 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 timely parallel equidirectional two-screw forcing machine is in the screw combinations situation that medium tenacity is sheared, practical 36 length-to-diameter ratios of twin screw extruder, keeping under the good vacuum state, with certain screw speed mixing extrusion, the water cooling bracing pelletizing has a halogen anti-flaming transparent polycarbonate material through what screening and dewatering made anti-stress cracking.
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.
