Description
Technical Field
The invention relates to a polycarbonate composition, in particular to a polycarbonate composition for a high-gloss oil-resistant switch panel and a preparation method thereof, belonging to the technical field of composite high polymer materials.
Background
Polycarbonate (PC) has the characteristic of high temperature resistance, has higher ball pressure temperature and glow wire temperature, and is the mainstream material in the fields of wall switches, controller shells and the like at present. However, when the polycarbonate resin is applied to a wall switch in a kitchen, cracks and even breakage may occur on the surface of a manufactured part, because the residual stress generated after the molecular chain of the polycarbonate is forced to be oriented is large, the polycarbonate resin is easily induced to crack after contacting with oil or an organic solvent, so that the use experience of a user is influenced, and even great personal and property losses are brought; in addition, the switch panel is a part of interior decoration besides the switch property, and at present, most markets are occupied by white switch panels with high whiteness and bright colors, so the appearance of materials for manufacturing the switch panel is very important, but the oil resistance and the glossiness of the formed parts of the existing polycarbonate materials for preparing the switch panel are difficult to achieve good effects at the same time.
In order to improve the condition that the existing polycarbonate material for the switch panel is not oil-resistant, in the prior art, modified nitrile rubber is added into polycarbonate resin, so that the oil-resistant cracking performance of the polycarbonate resin is obviously improved, and the modified nitrile rubber is suitable for kitchen environments with large oil smoke, but the addition of the nitrile rubber only prolongs the cracking time to different degrees, so that the cracking phenomenon cannot be completely eradicated, in addition, the addition of a large amount of rubber is not beneficial to the coloring of the material, and particularly, the modified nitrile rubber is greatly limited in the field of switch panels mainly taking white color as a main material.
Disclosure of Invention
in order to solve the technical problems, the invention provides a high-gloss oil-resistant polycarbonate composition for a switch panel and a preparation method thereof.
The technical scheme of the invention is as follows:
The polycarbonate composition for the high-gloss oil-resistant switch panel comprises the following components in parts by weight: 50-65 parts of polycarbonate, 25-30 parts of polyester resin, 4-7 parts of toughening agent, 1-6 parts of compatilizer, 2-10 parts of flame retardant, 1-5 parts of titanium dioxide, 0.01-2.0 parts of antioxidant and 0.2-0.8 part of other auxiliary agents.
Wherein the Polycarbonate (PC) is a thermoplastic aromatic polycarbonate polymer or copolymer having a branched chain obtained by reacting an aromatic hydroxy compound with phosgene or a carbonic acid diester, or reacting an aromatic hydroxy compound and a small amount of a polyhydroxy compound with phosgene or a carbonic acid diester. The method for producing the aromatic polycarbonate resin is not particularly limited, and conventionally known techniques such as a phosgene method (interfacial polymerization method) and a melting method (transesterification method) can be used. In the present invention, the molecular weight of the polycarbonate is suitably selected for the purpose of improving the appearance and flowability of the molded article, and is at least one of aromatic polycarbonates having viscosity average molecular weights of 10000-30000. The viscosity average molecular weight [ Mv ] obtained by converting the solution viscosity is usually 10000 or more, preferably 12000 or more, and usually 30000 or less, preferably 29000 or less. By setting the viscosity average molecular weight within the above range, the mechanical strength of the polycarbonate resin composition of the present invention can be ensured, and the polycarbonate resin composition is more preferable when used for applications requiring high mechanical strength.
Wherein the polyester resin is virgin polyethylene terephthalate with the intrinsic viscosity of 0.65-0.9 dl/g.

wherein the flame retardant is one of a phosphorus-nitrogen organic compound and a halogen-containing flame retardant. The phosphorus-nitrogen organic compound is preferably hexaphenoxycyclophosphazene, the halogen-containing flame retardant is preferably a bromine-containing flame retardant, and more preferably one or a mixture of two of brominated triazine, brominated epoxy, decabromodiphenylethane and brominated polyphenyl. The two flame retardants can greatly improve the glow wire temperature of the polycarbonate composition, have little influence on the heat-resistant temperature of resin, and can ensure that the composition passes a 125 ℃ ball pressure temperature test.
The titanium dioxide is rutile titanium dioxide with modified surface, and the titanium dioxide particles can be pure titanium dioxide or can contain other metal oxides, such as silicon dioxide, aluminum oxide and/or zirconium oxide, or phosphorus-containing compounds and the like. And the surface-modifying compound used in the modification treatment of the surface thereof is used to improve the surface wettability of the titanium dioxide particles or to add specific functional groups to the surface of the titanium dioxide particles, which treated titanium dioxide particles provide a white color when used herein in a polycarbonate composition, while not affecting the mechanical properties of the composition and the properties such as glow wire ignition temperature resistance.
