Description
Technical Field
The invention relates to the field of materials for compressor electric appliance shells, in particular to a high-temperature oil-resistant flame-retardant bio-based polycarbonate material and a preparation method thereof.
Background
Polycarbonate (PC) is a polymer containing carbonate groups in molecular chains, generally refers to bisphenol A type aromatic PC, and two preparation methods, namely a phosgene interface method and a molten ester exchange method (indirect phosgene and complete non-phosgene), are mainly adopted at present, and the Ningbo Zhejiang iron galenic company has marketed PC products, namely the green and environment-friendly complete non-phosgene molten ester exchange method is adopted. The bio-based PC is aliphatic PC with isosorbide replacing bisphenol A, and is called DURABIO by chemical commercial product name of Mitsubishi Japan. The common PC has ductility and toughness, and is widely used in various safety lampshades, signal lamps, transparent protective plates of stadiums and stadiums, lighting glass, high-rise building glass, CD discs, motorcycle driving safety helmets and the like. The areas where the largest amount of PC is used are computers, office supplies, automobiles, replacement glass and sheets. The bio-based PC is mainly used for automobile instrument panels at present, and is bright black and scratch-resistant. Ordinary PC is now cheap, 12 yuan per kg, while bio-based PC 90 yuan per kg.
Common PC is transparent and nontoxic, has good heat resistance and cold resistance, and is easy to generate stress cracking, because a benzene ring rigid group exists on a PC molecular chain, the steric effect is large, the high-temperature injection molding fluidity is general, the benzene ring molecular chain is difficult to be subjected to disorientation, the local stress of a workpiece is concentrated, and the workpiece can crack after the stress is released along with the time lapse. But the bio-based PC is completely different from the bio-based PC, does not contain benzene ring rigid groups, has very good fluidity and is the same as polypropylene resin, so the risk of stress concentration problem of a product is reduced by 80-90%. The best method for solving the problem of PC stress cracking is alloying, and the method comprises PC + toughening agent, PC + ABS, PC + PBT, PC + AS, PC + PET or ternary blend, and is applied in large batch in the market. At present, the focus of the modified PC is oil resistance, stress cracking resistance is focused before, and compared with the latter, the oil resistance difficulty is higher, namely, the modified PC can pass through the stress resistance through oil-resistant materials, and the requirement is higher. In the American group of the year, vegetable oil-resistant flame-retardant PC resin is required, wherein the vegetable oil comprises blend oil, peanut oil and corn oil, and the flame-retardant PC of a shell of a compressor electric appliance requires engine oil-resistant oil, wherein the blend oil comprises R134a, 600A, antirust oil and oil-resistant paint for an automobile door handle, so that the requirements of customers in the market prompt research and development personnel to find a solution hard to find, and a patent CN201510485848.2 discloses an oil-resistant flame-retardant polycarbonate material and a preparation method thereof, and the oil-resistant flame-retardant polycarbonate material is mainly used for kitchen wall switches (basically used at normal temperature); patent CN201180063799.3 improves the chemical resistance of PC materials by adding siloxane polycarbonate, and patent ZL201710419341.6 granted by this unit solves the high temperature oil resistance problem of PC, also alloyed and copolymerized PC.
Disclosure of Invention
The invention provides a high-temperature oil-resistant flame-retardant polycarbonate material and a preparation method thereof.
The technical scheme for solving the technical problems is as follows: a high-temperature oil-resistant flame-retardant polycarbonate material is prepared from the following components in percentage by weight:
on the basis of the technical scheme, the invention can further specifically select the following.
Specifically, the ordinary PC resin is a mixture of an aromatic polycarbonate with either or both of a low viscosity and a high viscosity at an arbitrary ratio. Zhejiang iron of China made in the strong wind with the brand name PC02-10 and kesi chuang low-viscosity PC 2405.
Specifically, the bio-based PC resin is D6350R manufactured by Mitsubishi chemical, melt index 12g/10min, 230 ℃ 2.16 kg.
Specifically, the brominated flame retardant is one of or a mixture of brominated triazine and tetrabromobisphenol A oligomer in any proportion. Compared with the conventional polybrominated diphenyl ether, the brominated flame retardant is safer due to no generation of toxic dibenzodithiane and polybrominated dibenzofuran during thermal cracking or combustion of high polymers.
Specifically, the toughening agent is an organic silicon toughening agent. The organic silicon toughening agent used in the invention takes acrylic acid and organic silicon as cores and methyl methacrylate or styrene-acrylonitrile (SAN) as shells, and has the capabilities of toughening, high temperature resistance, weather resistance, fire prevention assistance and the like.
Specifically, the auxiliary agent is prepared by mixing the following raw materials in parts by weight: 0.2-0.3 part of antioxidant; 0.3-1 part of ester exchange inhibitor; 0.4-0.6 part of high-temperature lubricant; 0.5-1 part of black master batch.
Specifically, the antioxidant is any one of or a mixture of two of a high-efficiency phosphite ester antioxidant S9228 and a thioether antioxidant 412S in any proportion.
Specifically, the high-temperature lubricant is pentaerythritol stearate (PETS), belongs to alkyd ester lubricants, has good internal and external lubricity, can improve the thermal stability of products, and is non-toxic.
Specifically, the black master batch is any one of or a mixture of polycarbonate-based black master batch and styrene-acrylonitrile-based black master batch in any proportion. The black master is one of color master batches, which is a plastic colorant formed by well dispersing a high proportion of pigment, additive and thermoplastic resin, namely, the thermoplastic resin is used as a carrier, and the preferred black master in the application takes polycarbonate or styrene-acrylonitrile as a carrier.
The invention also provides a method for preparing the high-temperature oil-resistant flame-retardant polycarbonate material, which comprises the following steps:
s1, processing and mixing raw materials: drying the PC resin until the water content is below 0.03%, and then adding the PC resin, the brominated flame retardant, the toughening agent and the auxiliary agent into a high-speed mixer according to corresponding weight percentages for fully mixing;
s2, melt extrusion: adding the mixed materials into a double-screw extruder for melt extrusion, wherein the extrusion temperature is 245-270 ℃, and the screw rotating speed is 350 revolutions per minute;
s3, granulation and post-treatment: and cooling, air-drying, granulating, strongly magnetizing and packaging the extruded material in sequence to obtain the high-temperature oil-resistant flame-retardant polycarbonate material.
The invention has the beneficial effects that:
the modified PC material prepared by using common PC and bio-based PC as main components and adding a proper amount of toughening agent, auxiliary agent and the like has good high-temperature oil resistance, can ensure that the PC material does not crack after being soaked in R134a halogenated hydrocarbon oil (R134a, R600a and R134a in antirust oil SNR-2000S have the strongest permeability) for 48 hours at the high temperature of 70 ℃, overcomes the defects of partial compatibility and reduced flame retardance caused by PC alloying in the prior art, and does not need to add more flame retardants including anti-dripping agents, compatilizers and ester exchange inhibiting agents. The bio-based PC provides ultrahigh fluidity, is well compatible with common PC, and has coexisting aliphatic and aromatic structures, thereby fundamentally reducing the internal stress of a workpiece and stress cracking of the workpiece; in addition, the high-temperature oil-resistant flame-retardant polycarbonate material provided by the invention has the characteristics of simple formula and preparation process, high production efficiency and convenience for industrialization.
