Description
Technical Field
The invention relates to the field of polycarbonate composite materials, in particular to an oil-resistant, heat-resistant and aging-resistant halogen-free flame-retardant polycarbonate composite material and a preparation method thereof.
Background
Polycarbonate (PC for short) is a thermoplastic non-crystalline engineering plastic, is a high molecular polymer containing carbonate groups in molecular chains, has excellent impact strength, thermal stability, glossiness, bacteria inhibiting property, flame retardant property and pollution resistance, and is the best choice for wall switches in the building industry and the like. But because of the existence of benzene ring in the PC molecular structure, the molecular chain rigidity and the steric hindrance are larger, the melt viscosity is large, the processing is difficult, and the residual stress of the product is larger in the processing and forming process; secondly, assembly stress is easily generated when the wall switch is fixed by a buckle or a tapping screw in the installation and assembly processes, so that residual stress and external assembly stress in the wall switch made of polycarbonate materials are easily induced and released under the environment with large oil smoke such as a kitchen, and the like, so that the product is cracked, the problem is brought to normal use of the product, meanwhile, potential safety hazards are brought to daily use of people, and the oil resistance is obviously necessary to be improved.
Secondly, the polymer material is easy to be degraded and aged under the comprehensive action of internal and external factors in the processing, storage and use processes. The reason for this is as follows:
1. internal factors are structure, e.g., containing unsaturated double bonds, branches, carbonyl groups, hydroxyl groups at the ends, etc. For example, diolefin-polymerized rubbers contain C ═ C double bonds, and are susceptible to thermal-oxidative aging, photo-oxidative aging, and ozone aging, thereby resulting in a decrease in material properties.
2. The external factors are mainly light, oxygen, ozone, heat, water, mechanical stress, high-energy radiation, seawater, salt spray, mold, bacteria, insects, etc. Some polymers are not aged as well, and when irradiated, especially by high-energy radiation, chemical bonds are broken, and even near-ultraviolet radiation is sufficient to open the normal single bond (except for the strong bond of C-H, O-H). The aging phenomenon is ubiquitous, and the normal use of the material is influenced, so that the aging is delayed.
Thirdly, the high molecular materials for electrics and electrics generally need flame retardant property, the flame retardance of plastics cannot meet the requirements, the flame retardant requirement can be met only by adding a fireproof agent, and as the environmental awareness of people is gradually enhanced, the halogen flame retardant generates carcinogens during combustion, so that the halogen-free flame retardant requirement is provided for the flame retardant modification of the plastics.
The Chinese patent application with the application publication number of CN 103524913A discloses a flame-retardant oil-resistant aging-resistant thermoplastic elastomer cable material, which is prepared from the following raw materials in parts by weight: polyvinyl chloride SG-3100 parts, nitrile rubber N2610-20 parts, polycarbonate 10-15 parts, polyethylene glycol terephthalate-1, 4-cyclohexane dimethanol ester 10-15 parts, silane coupling agent 15-20 parts, tetraphenyl- (bisphenol-A) diphosphate 30-40 parts, calcium carbonate 20-30 parts, calcium silicate 1-2 parts, barium stearate 30-50 parts, toluene diphenyl phosphate 10-15 parts, glycerol triglycerate 3-4 parts, cross-linking agent TAIC 2-3 parts, stearic acid 2-3 parts, N' -m-phenylene bismaleimide 1-2 parts, alcohol ester twelve 5-8 parts, PE wax 0.5-1 part, aluminum nitride powder 1-2 parts, jade powder 1-2 parts, and modified filler 8-10 parts. According to the technical scheme, the flame-retardant, oil-resistant and aging-resistant thermoplastic elastomer cable material has the characteristics of flame retardance, oil resistance, aging resistance, acid and alkali resistance through compounding of various components, is low in specific gravity and low in manufacturing cost, but is a soft material and cannot meet the ball pressure heat-resistant requirement of an electrical material.

The Chinese invention application with application publication number CN 105131546A discloses an oil smoke resistant polycarbonate material and a preparation method thereof, the oil resistance of the polycarbonate is improved by adding nitrile rubber, and the polycarbonate material mainly comprises: 70-90% of polycarbonate; 5-20% of modified nitrile rubber; 4-15% of a flame retardant; 0.3-3% of antioxidant; 0.4-3% of lubricant, wherein the modified nitrile rubber is prepared from nitrile rubber and ethylene methyl acrylate copolymer, and the mass ratio of the modified nitrile rubber to the ethylene methyl acrylate copolymer is 2-5: 1. according to the technical scheme, the material has good oil resistance and flame retardance through compounding of various components, but butadiene in the nitrile rubber has a large number of double bonds, so that the butadiene is easy to degrade under the thermal oxidation action of oil smoke to reduce the performance of the material, shorten the service life and yellow the appearance of the material, and secondly, because the rubber is not flame retardant, a large amount of low-molecular bromine flame retardant is required to be added to reach the flame retardant level of the material, so that the material cost is high.
Disclosure of Invention
The invention provides an oil-resistant, heat-resistant and aging-resistant halogen-free flame-retardant polycarbonate composite material which has excellent toughness, heat resistance, electrical insulation and aging resistance, is halogen-free, flame-retardant and environment-friendly, and has obviously improved oil cracking resistance.
The specific technical scheme is as follows:
the halogen-free flame-retardant polycarbonate composite material with oil resistance, heat resistance and aging resistance is characterized by comprising the following raw materials in percentage by weight:
the oil-resistant auxiliary agent is obtained by compounding silicone master batches and organic modified silicone oil, and the mass ratio of the silicone master batches to the organic modified silicone oil is 1: 1-10.
The silicone master batch is prepared by blending and granulating siloxane, silicon dioxide, a coupling agent and a carrier. Is often used as an external lubricant for improving the mold release property of the polymer material. The carrier comprises polycarbonate, styrene-acrylonitrile copolymer (SAN) and the like.
The organic modified silicone oil is prepared by replacing part of methyl groups in the methyl silicone oil with certain organic groups to improve the performance of the methyl silicone oil, and preferably, the organic modified silicone oil is alkyl modified silicone oil, the alkyl is a straight chain or branched chain alkyl with 8-12 carbon atoms, and more preferably octene.
According to the invention, the oil resistance of the polycarbonate composite material can be obviously improved by adding the compound oil-resistant auxiliary agent consisting of the silicone master batch and the organic modified silicone oil. If added alone, the oil resistance is not significantly improved. The reason for this analysis may be: after the organic modified silicone oil is added, the organic modified silicone oil can migrate to the surface of the material to form a layer of protective film, so that stress release caused by the swelling action of oil on the surface of the material is prevented from generating cracking to a certain extent, but the oil resistance effect is not obviously improved due to the non-uniformity of migration and dispersion. The silicone master batch can form strong intermolecular force with the organic modified silicone oil so that the silicone master batch can be more uniformly dispersed on the surface of the material, thereby obviously improving the oil-resistant effect.
In fact, the silicone is added in the form of master batch, which is used for better dispersion in matrix, such as directly adding silicone powder, but the silicone can be uniformly dispersed by strong shearing, and the strong shearing easily causes the material to degrade, yellow and black. Therefore, it is preferably added in the form of a master batch.
Preferably, the number average molecular weight of the polycarbonate is 2.8 to 3.2 ten thousand.
Preferably, the toughening agent is at least one selected from the group consisting of a terpolymer of methyl methacrylate-butadiene-styrene, a polyolefin elastomer, a silicone toughening agent, and ethylene-acrylate-glycidyl methacrylate.
Preferably, the flame retardant is at least one selected from the group consisting of a phosphorus flame retardant, a sulfonate flame retardant and a silicon flame retardant.
Preferably, the oil-resistant, heat-resistant and aging-resistant halogen-free flame-retardant polycarbonate composite material further comprises an antioxidant, an anti-hydrolysis stabilizer and a pigment.
More preferably, the antioxidant is selected from at least one of hindered phenols, phosphites and organic thioethers; and preferably a compound antioxidant prepared by mixing the antioxidant 1076, the antioxidant 168 and the antioxidant 412S according to the mass ratio of 2:1: 2.
The pigment is selected from rutile type or anatase type titanium dioxide.
On the basis of the preferable raw materials, the oil-resistant, heat-resistant and aging-resistant halogen-free flame-retardant polycarbonate composite material comprises the following raw materials in percentage by weight:
the mass ratio of the silicone master batch to the organic modified silicone oil is 1: 1.5-2.
Preferably, the toughening agent is selected from organosilicon toughening agents, and the flame retardant is selected from sulfonate flame retardants.
The invention also discloses a preparation method of the oil-resistant, heat-resistant and aging-resistant halogen-free flame-retardant polycarbonate composite material, which is prepared by blending all the raw materials according to a ratio and then extruding and granulating the mixture.
Preferably, part of polycarbonate is blended with a flame retardant, an antioxidant, a lubricant and an anti-hydrolysis stabilizer and extruded to prepare master batches, then the master batches are mixed with the rest raw materials, and the oil-resistant, heat-resistant and aging-resistant halogen-free flame-retardant polycarbonate composite material is obtained after extrusion. By adopting the preparation process, the master batch taking PC as a carrier has better compatibility with a resin matrix, and the material has better oil resistance and impact resistance.
Compared with the prior art, the invention has the following advantages:
the polycarbonate composite material disclosed by the invention adopts the compounded oil-resistant auxiliary agent consisting of the silicone master batch and the organic modified silicone oil, and the oil resistance of the composite material can be obviously improved by utilizing the mutual cooperation of the silicone master batch and the organic modified silicone oil. Meanwhile, the oil-resistant auxiliary agent and other components generate ideal synergistic action under specific content, so that the heat-resistant aging performance of the composite material can be further improved while excellent mechanical property, heat resistance and oil resistance are obtained, and especially yellowing can be reduced.
