Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to application of a polycarbonate composition, sulfonate and a phosphorus-containing compound in reducing fuming and heat release of polycarbonate.
Background
Polycarbonate (PC) extensively is applicable to the transportation trade, and to the aircraft cabin that personnel are highly concentrated, the space is narrow and small closed relatively, and in case the burning is fired to the material, will consume a large amount of oxygen, release the heat and produce poisonous combustible gas, and combustible gas can further combustion-supporting more heats of production, and the heat is concentrated the release and will be built a local high temperature environment, leads to the material to degrade with higher speed and produce more poisonous combustible gas. With the emphasis of people on the safety problem of traveling, the development of a product with low smoke density and low heat release during combustion and high-temperature heating is urgently needed by the market.
Chinese patent CN104830041A discloses a low-heat-release polycarbonate material, which mainly comprises a brominated flame retardant, semi-aromatic polyester and siloxane polycarbonate. However, the brominated flame retardant is not advocated under the trend of pursuing environmental protection at the present stage, and the smoke generated by the brominated flame retardant is generally very toxic and is not beneficial to escape of people in a closed space. And the reduction of smoke is not discussed in this patent.
In the prior art, the halogen-free polymer system focuses on optimizing the formula by evaluating the flame retardant grade, but the smoke release amount is less considered, and 85% of casualties in a fire disaster are caused by smoke, so that the smoke generation property of the polymer system is very necessary to be researched. Because the combustion mechanism and the smoke generation mechanism of the polymer are completely different, and when the flame retardant is added into the polymer, the combustion is more incomplete, and the smoke generation amount is generally increased, the polymer is difficult to have good smoke suppression effect and flame retardant effect simultaneously. Generally, the smoke release is reduced by adding a large amount of mineral filler. However, the toughness of the material is significantly reduced when too much mineral filler is added. In this case, in order to solve the problem of the decrease in toughness of the material, it is necessary to add a toughening agent, but the addition of the toughening agent increases the smoke emission and heat emission. Therefore, there is a need to effectively reduce the amount of mineral filler added.
Disclosure of Invention
The invention aims to provide a polycarbonate composition which has the advantages of low smoke and heat release under high temperature or during combustion and good toughness retention.
It is another object of the present invention to provide the use of sulfonates and phosphorus-containing compounds to reduce the smoke density and heat release rate of polycarbonates.
The invention is realized by the following technical scheme:
a polycarbonate composition comprises the following components in parts by weight:
100 parts of polycarbonate;
1-30 parts of boehmite;
0.1-1.5 parts of sulfonate;
1-12 parts of a phosphorus-containing compound;
the phosphorus-containing compound is at least one selected from hexabenzene oxygen cyclotriphosphazene, bisphenol A-bis (diphenyl phosphate), resorcinol bis [ bis (2, 6-dimethylphenyl phosphate) ], and triphenylphosphine oxide.
Other phosphorus-containing compounds and sulfonate have the functions of reducing smoke density and heat release rate after being compounded, but the effects of hexaphenyloxycyclotriphosphazene, bisphenol A-bis (diphenyl phosphate), resorcinol bis [ bis (2, 6-dimethylphenyl phosphate) ], and triphenylphosphine oxide are the best, and a polycarbonate composition with excellent low smoke density and heat release rate can be prepared under the condition of small addition amount.
Compared with the common phosphorus additives such as linear polyphosphazenes such as ammonium polyphosphate, triphenyl phosphate, tert-butyl triphenyl phosphate, tris (2, 6-xylyl) phosphate, resorcinol-bis (diphenyl phosphate), hexaaminocyclotriphosphazene, hexaanilinocytriphosphazene, poly (4-carboxyphenoxy) phosphazene and the like, the phosphorus-containing compounds (hexaphenyloxycyclotriphosphazene, bisphenol A-bis (diphenyl phosphate), resorcinol bis [ bis (2, 6-dimethylphenyl phosphate) ], triphenylphosphine oxide) have the most obvious reduction on the smoke density and the heat release rate of polycarbonate, have less reduction on the toughness of the polycarbonate composite material, and are more favorable for popularization and application. The hexaaminocyclotriphosphazene and hexaphenylaminocyclotriphosphazene have larger influence on the mechanical properties of the polycarbonate, and more toxic and harmful nitrogen oxides can be generated in the combustion process due to more nitrogen-containing groups; linear polyphosphazenes such as poly (bis (4-carboxyphenoxy) phosphazene) have poor compatibility with polycarbonate and are not as effective in actually reducing smoke density and heat release rate as hexaphenyloxycyclotriphosphazene, bisphenol A-bis (diphenyl phosphate), resorcinol bis [ bis (2, 6-dimethylphenylphosphate) ] or triphenylphosphine oxide.
The most common mineral filler in polycarbonate is talc, which also has some flame retardant properties. However, in order to promote the use of a polycarbonate composition having a low smoke density and a low heat release rate, it is necessary to maintain good toughness, and therefore, the selection of a mineral filler is required to maintain good toughness in addition to the low smoke density and the low heat release rate. The invention discovers that the addition of boehmite has better balance of toughness, smoke density and heat release rate, and is beneficial to preparing the polycarbonate composition with good comprehensive performance.
Polycarbonate resin: the polycarbonate resin of the present invention may be a branched thermoplastic polymer or copolymer obtained by the reaction of a dihydroxy compound or a dihydroxy compound thereof with a small amount of a polyhydroxy compound and phosgene (phosgene) or a carbonic acid diester. The production method of the polycarbonate resin is not particularly limited, and polycarbonate resins produced by a phosgene method (interfacial polymerization method) or a melting method (transesterification method) known so far may be used. An aromatic dihydroxy compound is preferable as the starting dihydroxy compound, and may be exemplified by 2, 2-bis (4-hydroxyphenyl) propane (═ bisphenol a), tetramethylbisphenol a, bis (4-hydroxyphenyl) -p-diisopropylbenzene, hydroquinone, resorcinol, 4-dihydroxybiphenyl and the like, of which bisphenol a is preferable. A compound in which at least one tetraalkylphosphonium sulfonate (tetraalkylphosphonium sulfonate) is bound to the aforementioned aromatic dihydroxy compound can also be used.
Of the foregoing, the polycarbonate resin is preferably an aromatic polycarbonate resin derived from 2, 2-bis (4-hydroxyphenyl) propane, or an aromatic polycarbonate copolymer derived from 2, 2-bis (4-hydroxyphenyl) propane and other aromatic dihydroxy compounds. The polycarbonate resin may also be a copolymer in which the main component is an aromatic polycarbonate resin, for example, a copolymer with a polymer or oligomer having a siloxane structure. Further, a mixture of two or more of the above polycarbonate resins may be used. The monohydric aromatic hydroxy compounds may be used to adjust the molecular weight of the polycarbonate resin, for example, m-methylphenol, p-methylphenol, m-propylphenol, p-t-butylphenol, and p- (long chain alkyl) -substituted phenols.
The method for producing the polycarbonate resin is not particularly limited in the present invention, and a polycarbonate resin produced by a phosgene method (interfacial polymerization method) or a melt method (transesterification method) can be used. The polycarbonate resin is also provided by subjecting the polycarbonate resin produced by the melt process to a post-treatment for adjusting the amount of terminal hydroxyl groups.
The sulfonate is selected from at least one of tetraethyl ammonium perfluoroethane sulfonate, potassium diphenylsulfone sulfonate, potassium perfluoroalkyl sulfonate, potassium benzenesulfonyl and sodium p-toluenesulfonate;
preferably, the sulfonate is selected from potassium perfluorobutyl sulfonate.
The phosphorus-containing compound is selected from at least one of hexaphenoxycyclotriphosphazene and resorcinol bis [ bis (2, 6-dimethylphenylphosphate) ]; the particle size of the boehmite is 0.1-13 microns. Further, the particle size of the mineral filler is 0.1 micron to 13 microns.
When the particle size of the mineral filler is less than 0.1 micron, the surface area is too large, the degradation effect on the polycarbonate is greatly improved under the same addition amount, and the particle size is too small, so that agglomeration is easy to occur, and the processing is difficult; when the particle size of the mineral filler is larger than 13 μm, the mechanical properties are insufficient. The particle size of the filler used in the production and testing process is typically distributed over a range, such as 4-6 microns, or more broadly, 3-7 microns.
In order to increase the anti-dripping performance of the composition when burning or receiving high temperature, 0-5 parts by weight of anti-dripping agent is also included; the anti-dripping agent is at least one selected from polytetrafluoroethylene, silicone-coated polytetrafluoroethylene, methacrylate polymer-coated polytetrafluoroethylene and styrene-acrylonitrile copolymer-coated polytetrafluoroethylene.
According to other performance requirements of the polycarbonate composition, 0-10 parts by weight of an auxiliary agent can be further included; the auxiliary agent is at least one of a heat stabilizer, an antioxidant, a light stabilizer, a plasticizer, a filler and a coloring agent.
The lubricant is metal stearate lubricant, alkyl stearate lubricant, pentaerythritol stearate lubricant, paraffin or montan wax.

The preparation method of the polycarbonate composition comprises the following steps: weighing the polycarbonate, the sulfonate, the phosphorus-containing compound, the boehmite and the auxiliary agent according to the proportion, then uniformly mixing in a high-speed mixer, and then putting into a double-screw extruder for extrusion and granulation to obtain the polycarbonate composition.
The application of sulfonate and phosphorus-containing compound in reducing fuming and heat release of polycarbonate comprises the following components in parts by weight:

0.2-0.8 part of sulfonate;
2-10 parts of a phosphorus-containing compound.
The phosphorus-containing compound may be used in any amount of 2 parts, 3 parts, 4 parts, to 12 parts.
As the amount of sulfonate is increased, the change in the smoke release and heat release rates is first decreased and then increased, and within the preferred range, the smoke release density and heat release rate are better controlled, and the toughness is less attenuated. However, too large an amount of the sulfonate added also causes the toughness of the composition to be lowered.

The particle size of the mineral filler is 0.1-13 microns.
The invention has the following beneficial effects
The invention discovers that the compounding of the sulfonate and the phosphorus-containing compound can effectively reduce the smoke release density and the heat release rate of the polycarbonate composition, and the dosage of the mineral filler can be effectively reduced in the application of preparing the low-smoke low-heat-release polycarbonate composition, so that the toughness of the material is well maintained.

It can be seen from comparative example 3 that the addition of a large amount of talc instead of sulfonate also reduced some smoke density and heat release rate, but the notched impact strength was greatly reduced.
As can be seen from comparative example 1/2, neither the addition of the sulfonate alone nor the addition of the phosphorus-containing compound had the function of simultaneously decreasing the smoke density and the heat release rate.
From example 3/5, it can be seen that the examples of potassium perfluorobutylsulfonate in sulfonate are superior in overall performance.

From examples 9-12, it can be seen that boehmite does not reduce smoke density and heat release rate as well as mica and talc, but it retains toughness well, and its combination of properties is more suitable for the preparation of polycarbonate composition products for a good range of applications.
