Description

Electronic apparatus highlight high-hardness dustproof ABS alloy material and preparation method thereof
Technical field
The present invention relates to macromolecular material and alloy technology field thereof, relate in particular to electronic apparatus highlight high-hardness dustproof ABS alloy material and preparation method thereof.
Background technology
The electronic apparatus shell of being made by the material of high surface gloss just becomes electronic apparatuss such as liquid crystal TV set manufacturer, sound equipment manufacturer, notebook computer manufacturer, MP3 manufacturer with its noble elegant, steady atmospheric outward appearance and is used for one of important means that attracts on human consumer's eyeball.Usually the high glossiness of electronic apparatus sheating material is mainly realized by having high gloss at its surface high optical coating of spraying or material itself.The construction of high optical coating is under suitable condition, generally not having a lot of problems occurs, if but in case run under the higher condition of temperature drift or humidity, problem such as the coating bubble can occur, come off, subside makes troubles for a lot of electronic apparatus manufacturing firm.Along with society is more and more higher to the cry of environmental protection, the solvent evaporates that the paint spay-coating construction produces also is subjected to environmental restraint gradually.
In recent years, the human consumer finds that progressively the macromolecular material electronic apparatus shell of high glossiness adsorbs dust easily because of static reason to be made dirty, with always leaving a trace after hand or the towel wiping, therefore influences the attractive in appearance of electronic apparatus greatly.This mainly be because in the air, on hand or leave a large amount of dusts on the towel, these dust small-particles and static electrification object near the time, because different electric charge attracts mutually, repel mutually with electric charge, its inner positive and negative charge is divided into positive and negative polarities as magnetic pole, therefore the static electrification object is very big to the short grained magnetism of dust, and the dust small-particle is adsorbed easily.Therefore, invent a kind of surface gloss height, surface hardness height and dust-proof macromolecular material, meet the market requirement of electronic apparatus and human consumer's needs.
The ABS(acrylonitrile-butadiene-styrene (ABS)) be vinyl cyanide, divinyl, three kinds of monomeric graft copolymers of vinylbenzene, its shock resistance is good, and machine-shaping easily is widely used in the electronic apparatus shell.But the surface gloss of ABS, surface hardness are generally lower.
The PMMA(polymethylmethacrylate) being synthetic glass again, is to be polymerized by methyl methacrylate monomer, has very high surface gloss and surface hardness, is widely used in electronic apparatus, instrument, light fixture and furniture.But the poor toughness of PMMA.
Mention the PMMA/ABS alloy in the patent " 200810241325.3 1 kinds of high-light ABS alloys and preparation method thereof " and have the surface of good glossiness, hardness height, good toughness.But that uses in its prescription has a surface gloss that may seriously reduce material because of the rubber content height, even may produce mixed color phenomenon.Simultaneously, because it does not add suitable dustproof auxiliary agent, therefore do not have dust reduction capability.
Mention in the patent " 200810203577.7ABS/PMMA matrix material " with rubber size in 100 ~ 400 nanometers, the toughness reinforcing increase-volume ABS/PMMA of MBS matrix material with bimodal distribution structure, mention the consistency that increases ABS and PMMA with MBS in the patent " 200510120989.0 improve the method for ABS and PMMA consistency ", mention surface hardness, tensile strength and the flexural strength of PMMA that in ABS, adds 25 ~ 30 parts in the patent " 200510120988.6 have ABS modified resin of high surface hardness and preparation method thereof " to improve ABS.Aforementioned all patents all do not relate to and how to overcome material surface and influenced problem attractive in appearance by contamination by dust easily.
