Abstract
The invention provides a high-transparency composite material and a manufacturing method thereof, which can solve the problems that the transparency effect needs to be further improved, the production cost is high and the like in the prior art. The technical scheme of the invention is that the material comprises the following components, by weight, 35-50 parts of polymethyl methacrylate, 35-40 parts of acrylonitrile-styrene, 20-30 parts of methyl methacrylate-acrylonitrile-butadiene-styrene and 0.2-0.8 part of polyvinyl alcohol; 0.1-0.2 part of dispersant, 2-6 parts of n-dodecyl mercaptan and 0.5-1.0 part of plasticizer. Experimental data show that the light transmittance of the invention is between 75 and 88, which is greatly superior to that of the prior art.
Description
Technical field
The present invention relates to plastic material, specifically, relate to a kind of high transparent plastics matrix material and manufacture method thereof.
Background technology
ABS resin has the excellent comprehensive performance, since coming out, obtained using widely, common ABS is by two inconsistent phases, be that the polybutadiene rubber graft copolymer is formed mutually with the SAN resin mutually, the light scattering effect that the difference of specific refractory power causes between its different microfacies makes material lose the transparency.If particle diameter is enough little, little of comparing with visible wavelength, can think that then two-phase optically is a homogeneous, so that product shows as is translucent.
In order further to widen the range of application of ABS resin, on the basis of basic its original excellent comprehensive performance of assurance, improve its transparency, preparation transparent ABS/PMMA resin by design to composition and microstructure.Transparent ABS/PMMA resin has outstanding transmittance and good processing properties and physical property, as resistance to impact shock and mouldability.The excellent combination property of transparent ABS/PMMA resin is so can be widely used in requiring simultaneously on the product of transparent and intensity, as electron device, business automation equipment and toy.In recent years, the demand growth of transparent ABS/PMMA resin is very fast both at home and abroad, the present domestic transparent ABS/whole dependence on import of PMMA resin, the potential market demand is more than 80,000 tons/year, along with China's sustained and rapid development of economy, a few years from now on China transparent ABS/PMMA resin market demand potential is bigger, and will become the importing country of transparent ABS/PMMA resin maximum in the world.
The principle of design of transparent ABS/PMMA resin is to keep under the prerequisite of higher structure of its micron-scale phase separation, by the chemical structure that means such as blend, copolymerization are regulated material, reduces rubber/the mould refringence of phase.Thereby eliminate light scattering effect and realize that visible region is transparent.Generally speaking, when differing, the two-phase specific refractory power just can reach enough transparencies less than 0.009 the time.
In recent years, people deepen day by day to the research of polymethylmethacrylate.Polymethylmethacrylate has the transparency of height, and goods are than light with volume unorganic glass goods.Simultaneously having certain impact strength and good low-temperature performance again, is the manufacturing important source material of air system and opticinstrument, makes transparent modified dose of ABS with it, can improve the transparency of ABS.
Though the prior art scheme provides the method for synthetic production transparent ABS/PMMA, working condition is required than higher, transparent effect is still undesirable, should need further to improve.
Summary of the invention
The invention provides a kind of high-transparence composite and manufacture method thereof, it can solve transparent effect that prior art exists and still need and further improve, and problem such as production cost height.
In order to reach the purpose that solves the problems of the technologies described above, technical scheme of the present invention is, a kind of high-transparence composite, it is characterized in that: described material comprises following component, by weight, polymethylmethacrylate 35-50 part, acrylonitrile-styrene 35-40 part, methyl methacrylate-acrylonitrile-butadiene-styrene (ABS) 20-30 part, polyvinyl alcohol 0.2-0.8 part; Dispersion agent 0.1-0.2 part, dodecyl mercaptan carbon 2-6 part, softening agent 0.5-1.0 part.
In technical scheme of the present invention, also have following technical characterictic: described dispersion agent is one or more in sodium lauryl sulphate, sodium metnylene bis-naphthalene sulfonate or the Sodium dodecylbenzene sulfonate.
In technical scheme of the present invention, also have following technical characterictic: described softening agent is one or more in cithrol, hexylene glycol two (2-ethyl) own ester or the polyglycol distearate.
A kind of manufacture method of high-transparence composite, described method is undertaken by following step:
(1) drying
With PMMA is being under 90～100 ℃ the condition dry 2～4 hours, and acrylonitrile-styrene, methyl methacrylate-acrylonitrile-butadiene-styrene (ABS) are respectively under 80～90 ℃ of conditions dry 3～5 hours.
(2) just mix
With polymethylmethacrylate, acrylonitrile-styrene, methyl methacrylate-acrylonitrile-butadiene-styrene (ABS), and polyvinyl alcohol, dispersion agent, dodecyl mercaptan carbon and softening agent according to the rules ratio of weight and number join in the high-speed mixer, the high-speed stirring batch mixing mixes various supplementary materials.
(3) extruding pelletization
Resulting mixture in the above-mentioned steps (2) joined in the twin screw extruder extrude, the extruded stock bar is through the tank cool to room temperature, after the air-blow drying machine drying, by the dicing machine granulation.
Described high-speed mixer is the stirring-type high-speed mixer.
Described forcing machine is that forcing machine is a twin screw extruder.
Each warm area temperature of described forcing machine is; One section: 140-170 ℃; Two sections: 180-210 ℃; Three sections: 200-240 ℃; Head 180-230 ℃.
The material that adds and starting material are compatible and refractive index is close is if the refractive index of two material less than 0.009, generally is transparent after this two material blend.The refractive index of PMMA is 1.492, the refractive index about 1.56 of AS, and the refractive index compromise of MABS 1.54PMMA, three material is about 1.54.Common ABS is by two inconsistent phases, and promptly the polybutadiene rubber multipolymer is formed mutually with the SAN resin mutually, and the light scattering effect that the difference of specific refractory power causes between its different microfacies makes material lose the transparency.The difference of rubber phase size and two-phase specific refractory power has determined the transparency of ABS.If the rubber phase particle diameter is enough little, little of comparing with visible wavelength, can think that then two-phase optically is a homogeneous, so that product shows as is transparent.The principle of design of transparent ABS resin is to keep under the prerequisite of higher structure of its micron-scale phase separation, by the chemical structure that the means of blend are regulated material, reduces rubber/the mould refringence of phase.Thereby eliminate light scattering effect and realize that visible region is transparent.Generally speaking, when differing, the two-phase specific refractory power just can reach enough transparencies less than 0.009 the time.Utilize MABS to be used as the basic moiety of ABS among the present invention, reduced rubber phase content, utilize MABS to be used as the basic moiety of ABS.Adopt the mode of AS, PMMA and MABS three component blend, three kinds of raw materials that refractive index is close manufacturing transparent material that combines.In the course of processing, utilize dispersion agent and softening agent, improve the flowability and the processing stability of mixed system, improve Drawing abillity, and make mixing of material, make the preparation method of transparent ABS/PMMA more simple and practical, and the performance variation of material is little.The present invention adopts the blend method preparation, goes for having now the client of the twin screw extruder production of directly reaching the standard grade, thereby has reduced cost.Compare with traditional production method, technology, equipment are simple, have reduced production cost.
