Abstract
A high-molecular polymer composition is prepared through mixing polycarbonate with ABS resin, mixing butanediol naphthalate, and adding triphenyl phosphate as flame retarding agent and RDP with cellular structure. Its advantages include high high-temp resistance, high speed of releasing internal stress, not deforming easily and low cost.
Description
The invention relates to the constituent and the compound method thereof of the high molecular polymer of the high heat-resisting and snap-out release internal stress of a kind of tool, particularly comprise and add a kind of polymkeric substance that discharges the internal stress time that shortens, be polybutylene terephthalate Poly (butylene terephtalate), the internal stress time of releasing of polymkeric substance can be significantly shortened in the adding of this polymkeric substance.
As everyone knows, the article of high temperature casting, the problem that after getting back to room temperature, must have internal stress, and the existence of internal stress can influence the ability of article opposing external force, and involve the problem that article are deformed by external force easily, so after the article manufacturing is finished, how in the shortest time, to discharge internal stress, required for market, become the problem that must face.General plasthetics needs for two to trimestral time discharge internal stress approximately, could sell, and need expend a large amount of waiting time and cost thus.TV shell commonly used is main constituent with polycarbonate (Polycarbonate) with ABS resin, and the resulting finished product of this prescription still needs one month time to discharge internal stress approximately.
Carry at the problems referred to above, the inventor designs in many ways, inquires into through secular based on the correlative study of engaging in related products for many years, exploitation, and the practical experience of selling, and through many times test and improvement, creates technical scheme of the present invention finally.
Main purpose of the present invention is to provide the constituent and the compound method thereof of the high molecular polymer of the high heat-resisting and snap-out release internal stress of a kind of tool, earlier with polycarbonate with after ABS resin is mixed, add polybutylene terephthalate again, this constituent makes article be about to internal stress when casting is finished to discharge about 95%, make article be packaged into sale during, remaining 5% internal stress can be discharged fully, needn't wait for for a long time, reach the purpose of enhancing productivity and reducing cost.
Secondary objective of the present invention is to provide the constituent and the compound method thereof of the high molecular polymer of the high heat-resisting and snap-out release internal stress of a kind of tool, in polybutylene terephthalate and polycarbonate and ABS resin constituent, add fire retardant triphenyl and cancellated fire retardant RDP again, this triphenyl is except reducing the combustibility, also can improve the flowability and the processibility of polymkeric substance, and then the fragility of reduction product, make product unlikely be full of cracks when using the screw spiral shell solid, and cancellated fire retardant RDP can improve the stability of product shape, increases impact strength and heat-resistant quality.
Further specify below in conjunction with preferred embodiment.
Embodiment 1
The constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of tool of the present invention comprises following compositions in portion by weight: polycarbonate 10-90 part, ABS resin 10-90 part, polybutylene terephthalate 5-45 part, triphenyl below 10 parts and cancellated fire retardant RDP below 10 parts.
The preparation steps of the constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of tool of the present invention comprised for two steps:
The first step is that polycarbonate 10-90 part is mixed earlier with ABS resin 10-90 part, makes to generate a polymkeric substance D;
Second step got 55～85% polymkeric substance D and mixes with 5～45% polybutylene terephthalate, and add the fire retardant triphenyl below 10 parts and cancellated fire retardant RDP below 10 parts, make the constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of tool of the present invention.
Wherein, the proportioning of constituent is parts by weight.
Embodiment 2
The constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of tool of the present invention comprises following compositions in portion by weight: polycarbonate 15-80 part, ABS resin 15-85 part, polybutylene terephthalate 5-40 part.
Its compound method is with embodiment 1, so do not repeat.
Embodiment 3
The constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of tool of the present invention comprises following compositions in portion by weight: polycarbonate 30-75 part, ABS resin 20-65 part, polybutylene terephthalate 15-35 part, 8 parts of triphenyl and cancellated fire retardant RDP are at 8 parts.
Its compound method is with embodiment 1, so do not repeat.
Embodiment 4
The constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of tool of the present invention comprises following compositions in portion by weight: polycarbonate 35-65 part, ABS resin 15-45 part, polybutylene terephthalate 10-30 part, 5 parts of triphenyl and cancellated fire retardant RDP are at 5 parts.
Its compound method is with embodiment 1, so do not repeat.
Wherein, polycarbonate (Polycarbonate) is with the reaction of derivative one phosgene of carbonic acid and diphenol and get, and this polymer property is good, has partially crystalline, transparent and quite high impact strength arranged.
And polybutylene terephthalate Poly (butylene terephthalate) is with dimethyl terephthalate (DMT) (dimethyl terephthalate, DMT) carry out transesterify and condensation, polymerization with butyleneglycol and get, the machinery of this polymkeric substance tool brilliance and electrical properties, for a long time place good anti-degree under the high temperature, extraordinary dimensional stability and extremely low creep, the strain of high resistance power, superiority such as chemical-resistant is good, processibility is good, crystallinity height are arranged under high heat.
With polybutylene terephthalate and polycarbonate blending, can be owing to the high strength and the high thermal resistance of the high crystalline and the polycarbonate of polybutylene terephthalate, overcome the size destabilization of polybutylene terephthalate and the shortcoming of finished product warpage, overcome polycarbonate simultaneously to the quick salty shortcoming of solvent, under complementing each other, obtain having the material of super high impact strength and good solvent resistance, thereby greatly overcome original defective after adding polybutylene terephthalate.
Fireproofing agent must be more rigorous to the addition of triphenyl, because this additive can produce consistency with main polymkeric substance composition, though so can improve the flowability of polymkeric substance, reduce the fragility of product, but if ratio is too much, can reduce the heat impedance and the crushing resistance of product on the contrary, however but the adding of meshy fire retardant agent RDP head it off just.
In sum, the invention relates to the constituent of the high molecular polymer of the high heat-resisting and snap-out release internal stress of a kind of tool, particularly comprise one and can shorten the polymkeric substance that discharges the internal stress time, polybutylene terephthalate, this polymkeric substance adds the internal stress time of releasing that can significantly shorten material.So the present invention is an effect that is rich in novelty, progressive and can supplies industry to utilize in fact.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to described feature of the scope of the invention and spirit change and modify, and all should be included within protection scope of the present invention.
