Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
The application provides a production system of a functional additive for a polyester film, wherein the functional additive can be a functional master batch prepared into a chip form. The polyester film added with the functional master batch can be applied to the application fields of glass, building materials, printing, medicine and health, optics, packaging and the like. The polyester film of the present invention may have a single-layer structure or a multi-layer structure. The functional masterbatch of the present invention is preferably added as a functional additive in the form of a chip to a polyester film of a single layer structure or a surface layer of a polyester film of a multilayer structure, for example, a surface layer and/or a bottom layer of a polyester film of a three-layer structure.
The polyester referred to herein is a polyester formed from one or more species selected from among polybasic carboxylic acids containing dibasic acids and their ester-forming derivatives, and one or more species selected from among polyhydric alcohols containing dihydric alcohols; or a polyester formed from a hydroxycarboxylic acid or an ester-forming derivative thereof; or a polyester formed from a cyclic ester. The polyester can be produced by a conventionally known method. For example, taking the preparation of PET as an example, it can be obtained by: a method of performing polycondensation after esterification of terephthalic acid and ethylene glycol; or a method in which an alkyl ester of terephthalic acid such as dimethyl terephthalate is subjected to a transesterification reaction with ethylene glycol and then subjected to polycondensation.
In the process of producing the polyester film, the functional master batch can be added into common polyester in a slicing mode, so that the produced polyester film has the functional characteristics of the functional master batch. For example, 1 to 30 wt% of the functional master batch of the present invention may be added to 70 to 99 wt% of polyester containing no other component, and then a polyester film is produced by processes such as extrusion and stretching, or a surface layer structure of a heat shrinkable film, a release film or an optical film is obtained by a multilayer co-extrusion process.
The functional master batch for the polyester film comprises a polyester carrier, polystyrene or polyethylene, polylactic acid, aerogel and polydimethylsiloxane. When the functional master batch is suitable for being added into the main polyester PET, for example, the polyester carrier of the functional master batch can be correspondingly selected to be the PET, so that the compatibility of the functional master batch and the main polyester PET is better, and the performance of the original polyester is prevented from being changed by unnecessary ester exchange. Likewise, when the functional masterbatch is suitable for addition to other host polyesters, such as PBT, PTT, PCT, or PETG, the polyester carrier in the functional masterbatch is preferably the same as the host polyester. Of course, under the conditions of similar properties and relatively good compatibility, the polyester carrier and the main polyester in the functional master batch can also be different, but the control of the product quality is possibly difficult. The silica aerogel in the functional master batch is commonly called as 'blue smoke', is a low-density silica aerogel which is porous and disordered and has a nano-scale continuous network structure, has a larger specific surface area than common silica, and is more difficult to disperse than common silica by using phosphate coupling agents and silane coupling agents (such as vinyltriethoxysilane, vinyltrimethoxysilane, vinyltris (beta-methoxyethoxy) silane and the like) in the prior art. Because of its very low density, it floats easily and cannot be dispersed into the polyester. The porous structure of the aerogel can generate strong bonding force with polylactic acid, polypropylene ethylene or polyethylene through polydimethylsiloxane, the density of the aerogel is increased, and the aerogel can be sunk into the polyester.
The polyester carrier in the functional masterbatch of the present application may be formed by, for example, polycondensation of a dibasic acid and a glycol. For example, the dibasic acid component thereof, including, but not limited to, terephthalic acid, isophthalic acid, 2, 6-naphthalenedicarboxylic acid, 3, 4 '-diphenylether dicarboxylic acid, hexahydrophthalic acid, 2, 7-naphthalenedicarboxylic acid, phthalic acid, 4' -methylenebisbenzoic acid, oxalic acid, malonic acid, succinic acid, methylsuccinic acid, glutaric acid, adipic acid, 3-methyladipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, 1, 11-undecanedicarboxylic acid, 1, 10-decanedicarboxylic acid, undecanedicarboxylic acid, 1, 12-dodecanedicarboxylic acid, hexadecanedioic acid, docosanedicarboxylic acid, lignoceric acid, dimer acid, 1, 4-cyclohexanedicarboxylic acid, 1, 3-cyclohexanedicarboxylic acid, 1-cyclohexanediacetic acid, fumaric acid, maleic acid, and hexahydrophthalic acid.

Further, these may be used alone or in combination of two or more.
The polyester carrier in the functional masterbatch of the present invention may be formed of hydroxycarboxylic acids and their ester-forming derivatives, or may be formed of cyclic esters.
For example, the hydroxycarboxylic acid component includes, but is not limited to: lactic acid, citric acid, malic acid, tartaric acid, glycolic acid, 3-hydroxybutyric acid, p-hydroxybenzoic acid, p- (2-hydroxyethoxy) benzoic acid, 4-hydroxycyclohexanecarboxylic acid and the like. The ester-forming derivatives of hydroxycarboxylic acids include, but are not limited to: dimethyl terephthalate, dimethyl isophthalate, dimethyl 2, 6-naphthalenedicarboxylate, dimethyl 3, 4 '-diphenylether dicarboxylate, dimethyl hexahydrophthalate, dimethyl 2, 7-naphthalenedicarboxylate, dimethyl phthalate, dimethyl 4, 4' -methylenebisbenzoate, dimethyl oxalate, dimethyl malonate, dimethyl succinate, dimethyl glutarate, dimethyl adipate, dimethyl azelate, dimethyl 1, 3-cyclohexanedicarboxylate and dimethyl 5-sulfoisophthalate. Further, these may be used alone or in combination of two or more. For example, cyclic esters include, but are not limited to: epsilon-caprolactone, beta-propiolactone, beta-methyl-beta-propiolactone, delta-valerolactone, glycolide, lactide, and the like. Further, these may be used alone or in combination of two or more.
The polyester carrier used in the present application is preferably polyethylene terephthalate, polybutylene terephthalate, polypropylene terephthalate, poly-1, 4-cyclohexanedimethanol terephthalate, polyethylene naphthalate, polybutylene naphthalate, polypropylene naphthalate, and a copolymer thereof, and particularly preferably polyethylene terephthalate (PET) and a copolymer thereof.
The polyester support of the present application is preferably produced industrially by a polycondensation method in which, for example, PET is esterified or transesterified with terephthalic acid or dimethyl terephthalate and ethylene glycol to produce bishydroxyethyl terephthalate, and the bishydroxyethyl terephthalate is polycondensed at high temperature under vacuum using a catalyst. In one embodiment, esterification can be carried out from terephthalic acid, ethylene glycol, cyclohexanedimethanol, a catalyst and a heat stabilizer; or esterification is carried out by taking terephthalic acid, ethylene glycol, isophthalic acid, a catalyst and a heat stabilizer as raw materials. In another embodiment, the catalyst is any one of Ti/Si series non-heavy metal catalyst and antimony trioxide, and the addition amount of the catalyst is 0.01-0.09% of the mass of the polyester. In another specific embodiment, the heat stabilizer is a phosphoric acid compound, and the addition amount of the phosphoric acid compound is 0.0003-0.030% of the mass of the polyester; the phosphoric acid compound comprises any one of phosphoric acid, phosphorous acid, polyphosphoric acid, trimethyl phosphate, triphenyl phosphate and triethyl phosphate. The preparation of the polyester support of another embodiment is as follows: adding 5.0kg of terephthalic acid, 2.2kg of ethylene glycol and 1.10g of germanium dioxide into a 20L general polymerization reaction kettle, carrying out esterification reaction at 230-265 ℃ and 0.2-0.3 Mpa (gauge pressure), releasing pressure to normal pressure when the water yield reaches 1200ml, adding 1.025g of triphenyl phosphate, stirring for 10 minutes at normal pressure, raising the temperature and reducing the pressure to 280 ℃ and below 100Pa, and after 1-3 hours of reaction, extruding, granulating and drying to obtain the polyester carrier.
In the functional master batch for the polyester film, the components except the polyester carrier can be uniformly mixed, extruded and granulated by using equipment such as an extruder to obtain functional material slices, then the functional material slices are added into the polyester carrier, and finally the functional master batch is prepared. That is, the functional masterbatch for polyester film of the present application includes a polyester carrier and a functional material chip including polystyrene or polyethylene, polylactic acid, aerogel and polydimethylsiloxane. Preferably, the functional material slice comprises the following components in parts by weight: 60-70 parts of aerogel, 10-15 parts of polylactic acid, 30-60 parts of polystyrene or polyethylene and 30-40 parts of polydimethylsiloxane. The functional material slices can be used as independent additives to be directly added into polyester to produce a polyester film, the properties of the independent functional material slices are soft, and in order to facilitate long-term storage and avoid pollution, the functional material slices are preferably added into a polyester carrier at the content of 30 wt% -40 wt% to prepare a functional master batch, namely, the content of the functional material slices in the functional master batch is 30 wt% -40 wt%. For example, in the process of preparing the polyester carrier, 60 parts by weight of functional material chips (the content of the functional material chips is 37.5 wt%) can be added into the polyester carrier per 100 parts by weight of the expected yield, and the functional material chips are uniformly mixed, extruded and cut into granules to obtain the functional master batch of the application.
In addition, because the content of the functional material slices in the prepared functional master batch is 30 wt% -40 wt%, in order to avoid the oxidation and decomposition of the effective components during storage, in the process of preparing the functional master batch, the functional material slices are preferably added into a polyester carrier at the content of 30 wt% -40 wt%, and 0.1 wt% -0.5 wt% of poly m-xylylene adipamide is simultaneously added.
When the functional material chips are added to the polyester carrier, the polylactic acid is easily decomposed into water and carbon dioxide at high temperature, thereby being separated from the aerogel. The silicon atoms of the aerogel are combined with the silicon atoms of the polydimethylsiloxane, the macromolecules at the other end of the polydimethylsiloxane can be combined with the alkane of the polyester, and the aerogel can still be kept in the polyester through the polydimethylsiloxane even if the affinity of polylactic acid is lost. And carbon dioxide generated by the decomposed polylactic acid can form bubbles to bring other solid inorganic particles in the polyester to the surface layer of the product, for example, a metal salt antioxidant, a catalyst and the like can be brought to the surface layer part of the polyester, so that a convex-concave structure can be formed on the surface of the polyester, the anti-blocking effect is realized, the adding amount of the inorganic anti-blocking particles can be reduced, and the light transmittance of the polyester is improved. For example, it is detected that the anti-blocking effect of the polyester film is not obviously changed and the light transmittance of the polyester film can be greatly improved under the condition of reducing the dosage of the anti-blocking particles by 20 to 30 percent.
In one embodiment of the present application, 60 to 70 parts by weight of aerogel particles having a particle size of 0.5 to 10 μm can be preferably dried at 120 ℃ for 4 hours; drying 10-15 parts by weight of polylactic acid particles with the particle size of less than 0.5mm at 110 ℃ for 4 hours; drying 10-15 parts by weight of polystyrene or polyethylene particles with the particle size of less than 0.5mm at 110 ℃ for 4 hours. And putting the dried particles into 30-40 parts by weight of liquid polydimethylsiloxane at normal temperature, and stirring at the speed of 1000-1500rpm for 2 hours to obtain a paste material. 20-45 parts by weight of polystyrene or polyethylene particles (which can be dried only in a purchased particle form without being crushed) dried at 110 ℃ for 4 hours are put into an extruder together with the paste material, and the mixture is melted, extruded, granulated and dried to obtain functional material slices after uniform mixing.
Polydimethylsiloxane is insoluble in water, has poor affinity with common inorganic particles, can be dispersed by shearing force of high-speed stirring, and is not suitable for being directly added into polyester. The silicon atoms of the polydimethylsiloxane can form firm molecular combination with the silicon atoms of the aerogel, the binding force is strong, and the polydimethylsiloxane and the aerogel cannot be separated by applying high-speed stirring. The polymer at the other end of the polydimethylsiloxane can be combined with the alkane of the polyester, and the binding force is strong. Not only has good dispersion effect, but also can not be separated from the combination to generate agglomeration phenomenon due to the molecular combination. While the ordinary silicon dioxide has smooth surface and insufficient bonding force with the existing coupling agent, the ordinary silicon dioxide can be separated from the coupling agent when the stirring force is too large during dispersion, and the ordinary silicon dioxide can still agglomerate when added into polyester.
The functional material slices can be selectively put into the polyester carrier in the preparation process of the polyester carrier, for example, the functional material slices can be put into the esterification stage in the preparation process of the polyester carrier, or after the esterification, or in the polycondensation stage, or after the polycondensation is completed, and finally, the functional master batch for the polyester film is obtained by extrusion granulation.
Preferably, the functional material chip selection of the present application is put into the polycondensation stage of the polyester carrier, for example, referring to the preparation steps of the polyester carrier described previously, the functional masterbatch for the polyester film of the present application can be prepared by the following steps: adding terephthalic acid, ethylene glycol and germanium dioxide into a general polymerization reaction kettle, carrying out esterification reaction at 230-265 ℃ and 0.2-0.3 Mpa (gauge pressure), after the esterification is finished, releasing the pressure to normal pressure, adding triethyl phosphate and functional material slices for polycondensation, stirring for 10 minutes at normal pressure, raising the temperature and reducing the pressure to 280 ℃ and below 100Pa, after the reaction is finished for 1-3 hours, extruding, granulating and drying to obtain the functional master batch. As described above, 0.1 to 0.5 wt% of poly (m-xylylene adipamide) may be added simultaneously with the addition of the functional pellet.
Through detection, after the functional master batch is added, the influence on the viscosity of the original polyester is small, and the stability of the parameters of the polyester film is favorably maintained. In addition, the glossiness, the wear resistance, the high temperature resistance and the heat insulation performance of the polyester film are all improved by 10 to 20 percent.
The production method of the functional masterbatch of the present application will be described in detail with reference to the functional masterbatch production system for polyester film of the present application shown in fig. 1.

A small amount of m-xylylene adipamide may be added simultaneously with the addition of the functional material chips. Of course, it should be understood by those skilled in the art that the polyester carrier preparation mechanism 100 of the present application is not limited to only one esterification reaction kettle and one polycondensation reaction kettle connected in series therewith, and for example, in the known five-kettle production process, two esterification reaction kettles and three polycondensation reaction kettles are generally connected in series in sequence, wherein the first two polycondensation reaction kettles are used for the pre-polycondensation reaction, and the last polycondensation reaction kettle is used for the final polycondensation reaction. The functional material slices can be selectively added into any one polycondensation reaction kettle, and preferably the functional material slices are added into the polycondensation reaction kettle of the final condensation reaction, so that unnecessary copolymerization impurities are prevented from being introduced, and the characteristics of the functional material are prevented from being influenced.
