Description

A kind of oil resistant, low temperature resistant regeneration ABS/PBT alloy material
Technical field
The present invention relates to technical field of polymer materials, be specifically related to a kind of oil resistant, low temperature resistant regeneration ABS/PBT alloy material Material.
Background technology
Acrylonitrile-butadiene-styrene (ABS) (ABS) is because of its excellent mechanical property, dimensional stability, it is easy to process, colour, The features such as post-treatment is convenient and be widely used in each field of social life, be that current production rate is maximum, most widely used polymerization One of thing.ABS has higher melt strength simultaneously, the advantage that extrusion performance is good.But ABS plastic there is also thermal deformation simultaneously The shortcomings such as temperature is relatively low, chemical resistance especially oil resistivity, weatherability are poor, limit its application.
Polybutylene terephthalate (PBT) is that a kind of crystalline thermoplastic polyester has nontoxic, against weather, anti-chemistry Stability of drug products is good, mechanical strength advantages of higher and prominent oil resistant solvent resistance, but owing to the crystallization rate of PBT is the highest, Viscosity is the lowest, and melt strength is the highest, it is difficult to extrusion molding.
Carry out ABS Yu PBT being blended and can be effectively improved the performances such as the weatherability of ABS material, oil resistivity, solvent resistance, Improve the application space of material greatly, can be widely applied to the social life every field such as pipeline, architectural shape and sheet material.
ABS and PBT is conventional material, whether ABS or PBT material, all can produce substantial amounts of defective material or substandard products, Recovery article, owing to recovery article is after using for a long time, all there occurs in various degree is aging, its reworking performance, tough Property etc. deterioration occurs, therefore at present process for ABS, PBT defective material, substandard products or recovery article mainly has in the following manner.
(1) burning or land-fill method, owing to can produce the harmful gass such as sulfur dioxide in burning process, easily cause ring Environment pollution, and take land-fill method, environment also can be caused the biggest harm, current this mode by the refractory organics of ABS and PBT The most progressively it is eliminated.
(2) defective material, substandard products or recovery article are simply recycled and do not carry out any modification, be downgraded to commonly mould Material uses, although solving problem of environmental pollution, but fail to make full use of the economic worth of these defective materials, range of application is narrow.
(3) carry out composite modified by ABS or the PBT reworked material of interpolation part with corresponding ABS, PBT virgin material, again obtain Obtain the preferable ABS of performance, PBT material accordingly.As Chinese patent CN 201110188049.0 discloses a kind of Merlon/ ABS and preparation method and application, it uses PC virgin material, PC reworked material and ABS reworked material to be that main component is modified, carries Its forming property high, it is thus achieved that a kind of modified PC/ABS alloy material.But, prior art does not have and can adopt completely It is the scheme that bulk composition improves with ABS, PBT reworked material.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of oil resistant, low temperature resistant regeneration ABS/PBT alloy material, resin ABS, PBT reworked material selected completely by material, by the toughener in technical scheme, compatilizer preferably and collocation, it is thus achieved that The regeneration ABS/PBT alloy material that a kind of performance is excellent.
In order to realize the technical purpose of the present invention, the present invention adopts the following technical scheme that.
A kind of oil resistant, low temperature resistant regeneration ABS/PBT alloy material, by mass percentage, including following component: ABS again Raw material 48% ~ 78%, PBT reworked material 10% ~ 40%, compatilizer 2% ~ 5%, EMA toughener 2% ~ 3%, MBS(methyl methacrylate-fourth Diene-styrene copolymer) toughener 5% ~ 12%, antioxidant 0.3% ~ 0.6%, lubricant 0.3% ~ 0.6% and Nano filling 1-2%.
Preferably, described EMA toughener is preferentially from the product of 1125 AC models of du pont company.
Preferably, by mass percentage, in described ABS reworked material, PC/ABS alloy content is less than 10%.
Preferably, described compatilizer is SAG(styrene-acrylonitrile-glycidyl methacrylate copolymer), Malaysia At least two in acid anhydride-grafted acrylonitrile-butadiene-styrene (ABS), styrene-maleic anhydride copolymer, and one therein is SAG。
The most particularly select compatilizer SAG(styrene-acrylonitrile-glycidyl methacrylate copolymerization Thing), by the chain extension graft reaction between SAG and ABS, PBT, significantly improve ABS, PBT reworked material processing fluidity, make regeneration ABS/PBT alloy material has good strength character, overcomes part of having in existing ABS/PBT alloy material and uses ABS, PBT virgin material improves the defect of its shaping strength.
Preferably, described compatilizer is SAG.
Preferably, described antioxidant be mass ratio be the antioxidant 1076 of 1:2 and irgasfos 168 is compounding forms.
Preferably, described lubricant is calcium stearate, magnesium stearate, stearic amide, methylene bis stearic amide or second At least one in the double stearic amide of support.
Preferably, the one during described Nano filling is nanomete talc powder, nano titanium oxide, nano zine oxide.
It is further preferred that the particle diameter of described Nano filling is 20-120nm.
The invention have the advantages that: the invention provides a kind of oil resistant, low temperature resistant regeneration ABS/PBT alloy material Material, compared with prior art, has the advantage that
The regeneration ABS/PBT alloy material that the present invention provides, uses regeneration ABS, PBT resin material, it is not necessary to add completely ABS, PBT virgin material, is significantly improved the utilization rate of regeneration ABS, PBT, and is changed by the feature of ABS and PBT reworked material Property, it is thus achieved that a kind of oil resistant, low temperature resistant, impact strength is good, processability is good regeneration ABS/PBT alloy material, for ABS, The utilization of PBT reworked material is made that prominent contribution.
EMA toughener and MBS toughener is used to carry out composite toughening, by the optimum option to toughener, to regeneration ABS/PBT alloy material is modified, and significantly improves the impact strength of regeneration ABS/PBT alloy material, it is thus achieved that meet The regeneration ABS/PBT alloy material of performance requirement.
Use compatilizer SAG(styrene-acrylonitrile-glycidyl methacrylate copolymer), by SAG Yu ABS, Chain extension graft reaction between PBT, significantly improves ABS, PBT reworked material processing fluidity, makes regeneration ABS/PBT alloy material have There is good shaping strength, overcome part of having in existing ABS/PBT alloy material and use ABS, PBT virgin material to improve it The defect of shaping strength, has the performance not being weaker than ABS, PBT virgin material, it is achieved that environmental protection, the warp to ABS, PBT reworked material Ji utilizes, and has great economic worth and social value.
By employing Nano filling to ABS/PBT composite modification, at nanoparticle and ABS reworked material, PBT reworked material Between under the thread connection that formed and molecular force, make the microcrack in ABS/PBT composite become micro-crack, stop oils Material corrodes further, improves the oil resistivity of ABS/PBT composite.
