Abstract
The invention discloses a PC (polycarbonate) material which comprises the following components in percentage by weight: 72.5-96 percent of PC, 1.0-5.0 percent of a luminous agent, 1.0-15.5 percent of a stress cracking-prevention modifier, 0.1-2.0 percent of an antioxidant, 0.1-2.0 percent of a lubricant and 1.3-5.5 percent of other additives. The PC material can automatically release light ray energy absorbed in case of existing of light rays to automatically give out light under the conditions of no other energy support and no light ray irradiation, has the light very easy to recognize clearly, is attractive in product appearance and good in shock strength, and improves the shortcoming that a PC material injection moulding product has high probability of stress cracking. Meanwhile, the PC material is convenient in production and procurement, and can meet all environment-friendly requirements, and therefore has comprehensively improved product competitiveness.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of polycarbonate material.The invention still further relates to the method for making this polycarbonate material.
Background technology
Be accompanied by the use of biomass energy, wind energy, sun power, water energy, fossil energy, nuclear energy etc., the mankind progressively move towards agricultural civilization and industrial civilization from First Contact.And along with the continuous growth of population in the world and economic scale, the energy uses the environmental problem brought and inducement thereof constantly by people are familiar with, the not just harm of smog, photo-chemical smog and acid rain etc., atmospheric carbon dioxide levels raises the Global climate change of bringing, and has also been confirmed to be undisputable fact.Under this background, a series of new ideas, the new policies such as " carbon footprint ", " low-carbon economy ", " low-carbon technology ", " low carbon development ", " low-carbon (LC) mode of life ", " low-carbon (LC) society ", " low-carbon (LC) city ", " Low Carbon World " are arisen at the historic moment, can say that current social is very high for energy-saving and emission-reduction, low-carbon economy cry, the Chinese government promotes energetically.The mechanical property of polycarbonate material own is good, and gloss is splendid, and moderate cost, if possess noctilucence feature, is convenient to injection molding again, will play good social agency, creates good economic worth simultaneously.
Summary of the invention
The object of the invention is to, provide a kind of under dull thread radiation situation, do not need external any energy support, the light ray energy absorbing can automatically be released in light time and automatic luminous and the injecting products that has improved polycarbonate material easily produce the polycarbonate material of the shortcoming of stress cracking phenomenon.
Technical scheme provided by the invention is as follows: it is made up of by weight following composition, polycarbonate: 72.5-96%; Luminous agent: 1.0-5.0%; Anti-stress cracking properties-correcting agent: 1.0-15.5%; Oxidation inhibitor: 0.1-2.0%; Lubricant: 0.1-2.0%; Other auxiliary agents: 1.3-5.5%.
The preparation method of polycarbonate material of the present invention, after comprising the steps: first polycarbonate and anti-stress cracking properties-correcting agent, oxidation inhibitor, luminous agent, lubricant, other auxiliary agents proportionally to weigh in mixer low speed mixing 10 minutes, after in the screw combinations situation sheared at some strength through parallel equidirectional two-screw forcing machine in time again, keeping under good vacuum state, with certain screw speed mixing extrusion, water cooling bracing pelletizing makes polycarbonate material through screening and dewatering.
Polycarbonate material of the present invention, under dull thread radiation situation, do not need external any energy support, the light ray energy absorbing can automatically be released in light time and automatic luminous, its light is easy to clear identification, product appearance is attractive in appearance, resistance to impact shock is good, and the injecting products that has improved polycarbonate material easily produces the shortcoming of stress cracking phenomenon, and production procurement is convenient, also meet all environmental requirements, comprehensive like this product competitiveness that improved simultaneously.
Embodiment
Be below the embodiment of polycarbonate material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment mono-, provides a kind of polycarbonate material, is made up of by weight polycarbonate: 90.0% following composition; Anti-stress cracking properties-correcting agent: 4.0%; Luminous agent: 3.2%; Oxidation inhibitor: 1.0%, lubricant: 0.3%; Other auxiliary agents: 1.5%.
First by polycarbonate and anti-stress cracking properties-correcting agent, oxidation inhibitor, luminous agent, lubricant, after other auxiliary agents proportionally weigh in mixer low speed mixing 10 minutes, mixer adopts low speed mixing, stainless steel, paddle should be less than 0.5 centimetre with barrel gap, supplementary material mixed effect should visual various particles and powder substantially even, there is no obvious agglomerate or gather, and then in the screw combinations situation of shearing at some strength through parallel equidirectional two-screw forcing machine in time, twin screw extruder uses 36 length-to-diameter ratios, keeping under good vacuum state, with certain screw speed mixing extrusion, water cooling bracing pelletizing makes polycarbonate material through screening and dewatering.
The above; it is only 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; the variation that can expect without creative work or replacement, within all should being encompassed in 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.
