The composite material disclosed by the invention is excellent in comprehensive mechanical property and wide in application range; and the preparation method for the composite material is simple, and easy to operate.
Description
Technical field
The present invention relates to polymeric material field, particularly a kind of new A BS/PC/PMMA composite manufacture method.
Background technology
The terpolymer that ABS (Acrylonitrile Butadiene Styrene) resin is comprised of vinyl cyanide, divinyl and vinylbenzene.The ABS resin is because showing three kinds of synergisticing performances between the component; so have the surface hardness height, tough and tensile, low-temperature impact resistance good, creep resistant good, good stability of the dimension, molding shrinkage are little; the good excellent properties that waits of processing characteristics; be widely used in household electrical appliance; mechanical fitting; office appliance; electron device; the vast field such as automotive industry; but the ABS scraping and wiping resistance performance is relatively poor; usually can adopt the method for spraying to improve the scraping and wiping resistance performance of material surface, but the spraying meeting bring pollution to environment for this reason, and very difficult recycle and reuse.
PC is a kind of line style carbonic acid polyester, carbonic acid group and other group alternative arrangements in the molecule, these groups can be aromatic series, can be aliphatics, also can both.Bisphenol A-type PC is most important Industrial products.PC is the amorphous polymer of almost colourless vitreous state, has well optical.The PC high molecular weight resin has very high toughness, and the socle girder notched Izod impact strength is 600～900J/m, and the heat-drawn wire of not filling the trade mark is approximately 130 ℃, can make this numerical value increase by 10 ℃ after glass fibre strengthens.The modulus in flexure of PC can reach more than the 2400MPa, and resin can be processed into large rigid articles.When being lower than 100 ℃, the creep rate under load is very low.PC has preferably hydrolytic resistance, but can not be used for repeating to stand the goods of high pressure steam.PC salient features defective is that stability to hydrolysis resistance is not high enough, and is responsive to breach, anti-organic chemistry moral character, and the scratch resistance trace is relatively poor, and long-term exposure can jaundice in ultraviolet ray.The same with other resins, PC is subjected to soaking of some organic solvent turbid easily.
PMMA is a kind of thermoplastics, has splendid weathering resistance, and higher surface hardness has preferably impact property, good processing characteristics is arranged, high transparency is arranged, transmittance can see through visible light 99% up to 91%～93%, UV-light 72%, quality is light, has outstanding weathering resistance.But the PMMA melt viscosity is higher, and rate of cooling is very fast again, and goods produce internal stress easily, so strict to process regulation during moulding, also needs to carry out aftertreatment behind the product molding.PMMA has the Room Temperature Creep characteristic.Along with load strengthens, the time growth, can cause the stress cracking phenomenon.
Because shortcomings such as not high, the easy snag of PMMA surface hardness, shock resistance are low, moulding poor mobile performances, the modification of PMMA occurs in succession.Such as the copolymerization of methyl methacrylate and vinylbenzene, divinyl, the blend of PMMA and PC etc.Super transparent PMMA material is mainly used in protecting screen of mobile phone; this product is divided into hardening coat; there are not two kinds of hardening coats. be characterized in that transmittance is fabulous; there is not impurity; the electrostatic protection film; the thick rear hardness of surface hardening can reach more than the 5-6H. and at present special recommendation is used for the PMMA material of hardening treatment, domesticly is called living plate.
ABS, PC, PMMA are a kind of as macromolecular material, namely has its advantage, the shortcoming that himself is arranged again, these three kinds of macromolecular materials are mixed and made into alloy, can effectively utilize the advantage of differing materials, by optimizing proportioning, can make the matrix material of mechanical property excellence, range of application Guan Guang.
Summary of the invention
The objective of the invention is to overcome the defective of existing macromolecular material, a kind of composite manufacture method with excellent comprehensive mechanical property is provided.
In order to realize above goal of the invention, the present invention by the following technical solutions: a kind of preparation method of novel alloy may further comprise the steps:
(1) prepares 10～20 parts of raw material: ABS by following mass fraction; 40～60 parts of PC; 20～40 parts of PMMA; 2～6 parts of compatilizers; 0.1～0.5 part of lubricant; 2～4 parts in oxidation inhibitor;
(2) pour ABS, PC, PMMA and compatilizer into high-speed mixer and mixing 10～20min, add lubricant and oxidation inhibitor, continue to mix 10min;
(3) with dual-screw-stem machine with the raw material extruding pelletization that mixes, material granule is at 80 ℃ of dry 5h.
Described compatilizer is the styrene-acrylonitrile-butadiene terpolymer, and molecular-weight average is 1～40,000, and its particle size range is between 100～300nm.
The ABS resin have the surface hardness height, tough and tensile, low-temperature impact resistance good, creep resistant good, good stability of the dimension, advantage that molding shrinkage is little, shortcoming is that scraping and wiping resistance performance is relatively poor; PC has that good light transmission, resisting heat distortion performance, high impact properties, hardness are high, good weatherability, and shortcoming is not ultraviolet resistance, not anti-highly basic, is subject to the erosion of organic solvent.PMMA has splendid weathering resistance, and higher surface hardness has good processing characteristics, high transparency is arranged, but melt viscosity is higher, rate of cooling is very fast again, goods produce internal stress easily, so strict to process regulation during moulding, also need to carry out aftertreatment behind the product molding.PMMA has the Room Temperature Creep characteristic.Along with load strengthens, the time growth, can cause the stress cracking phenomenon.
The characteristics of comprehensive ABS, PC, three kinds of macromolecular materials of PMMA, regulate the proportioning of three kinds of materials, it is 10～20 parts at ABS, PC is 40～60 parts, PMMA is 20～40 parts, the surface hardness of matrix material, toughness, shock-resistance, processing characteristics all reach optimum regime, combine the advantage of three kinds of macromolecular materials, have weakened simultaneously three kinds of macromolecular materials shortcoming originally.
Major advantage of the present invention and beneficial effect are:
(1) the matrix material comprehensive mechanical property that makes of the present invention is excellent, has wide range of applications;
(2) composite material and preparation method thereof of the present invention is simple, easy handling.
