Description
Technical field
The invention belongs to the modified field of Material Physics, it is related to a kind of high transmission rate, the preparation method of heat-resisting PC/PAR alloys.
Background technology
With the development of modern science and technology, the application of high performance engineering plastics composite is particularly important with development, hair
Toward more using single engineering plastics, as study on the modification object, but in some special dimensions, single engineering plastics have met
Demand is wanted in not its development.In recent years, by two or more plastics using physical blending or the method for chemical graft
And high-performance, the engineering plastic alloy of multifunction for obtaining, can improve or improve the performance and reduces cost of present plastics, altogether
In mixed modification, physical blending accounts for more than 80% in actual applications.Engineering plastics physical blending prepares high performance alloys maximum
Problem is exactly the compatible problem between two kinds of plastics, and its compatibility directly determines the combination property of engineering plastic alloy.
Makrolon has good physical mechanics property, heat resistance, translucency and chemical stability, but including electronics electricity
Numerous high-technology fields such as device, instrument, Aero-Space, automobile are carried to the mechanical performance of makrolon, optical property, hot property
Requirement higher is gone out.Therefore, realize that high intensity, high temperature resistant, transparency of makrolon etc. are the developing direction of makrolon.
Poly- aryl acid esters is bisphenol A-type polyester construction, has certain compatibility with makrolon from structure, and the transparency is good,
If PAR and PC be blended, the heat resistance of makrolon can be significantly improved and its transparency is kept, makrolon is expanded significantly
Range of application.
Makrolon is blended with polyarylate, and blend has two glass transition temperatures, corresponds respectively to PAR and PC.But warp
After appropriate temperature mixing, due to there occurs ester exchange reaction, new cocondensation type polyester is generated, it serves the work of compatilizer
With PC/PAR blends turn into compatible system, and only one of which corresponds to the glass transition temperature of this compatible system, and its is corresponding
Plastic alloy occurs in that certain cooperative effect in the physical properties such as heat resistance, also.
The content of the invention
The technical problem to be solved in the present invention is the degree of product ester exchange that solves, and light transmittance, easy processing, height are heat-resisting, and
A kind of high transmission rate, heat-resisting PC/PAR alloys are provided.
To achieve these goals, the present invention provides a kind of high transmission rate, heat-resisting PC/PAR alloys, may be by following skill
Art scheme realizes, i.e., a kind of high transmission rate, heat-resisting PC/PAR alloys, by unsaturated dibasic acid, makrolon, poly- aryl acid
Ester, unsaturated dicarboxylic acid monomer, ester exchange inhibitor, antioxidant, lubricant, compatilizer, are prepared by the way that ester exchange reaction is blended
Obtain, the high transmission rate, heat-resisting PC/PAR alloys are made up by weight percentage of following component：
Described makrolon is one or more in middle and high, low gluing；
Described poly- aryl acid esters is the polyester of bisphenol A-type；
Described antioxidant is one or more in phosphorous acid esters, Hinered phenols, thio-2 acid 2 stearyl ester；
Described ester exchange agent is species well known to those skilled in the art, and what is used is manganese acetate, phosphorous triphenyl phosphate
One or more in ester system, Sodium Acid Pyrophosphate；
The preparation method of PC/PAR alloys in the present invention, it is characterised in that first ester exchange agent is diluted in lysate, is treated
In being mixed into mixer together with makrolon, poly- aryl acid esters after being completely dissolved, high-speed stirred 5 minutes is then sequentially added anti-
The high-speed stirred such as oxygen agent, lubricant, compatilizer 3-5 minutes, in discharging feeding double screw extruder, then extruded machine melting modeling
Change, head extrusion, tie rod, cooling, pelletizing, drying, obtain finished product.
The processing temperature of described double screw extruder is 260-320 DEG C, and screw speed is extruded at 300-400 revs/min
Type is 35 machines；
The present invention is obtained a kind of high transmission rate, heat-resisting PC/PAR alloys using above-mentioned formula and processing method, and its advantage is
The compatilizer of the alloy is good, and high light transmittance is maintained while compatibility is improved, hence it is evident that the temperature classification of lifting material, expands
Use scope, low residual amt, have no irritating odor, be conducive to that environmental protection and people's is healthy；Processing technology is simple, easily
In large-scale production；
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.
Implement one：
