The present invention relates to an acrylic resin composition having antistatic properties. Acrylic resin is known for its transparency, good mechanical properties, workability, and beautiful appearance, and is widely used in various decorative items, lighting equipment, signboards, nameplates, etc. Since the electrical insulation property is very high, it is difficult for static electricity generated by contact or friction to dissipate, and it is often experienced that dust and dirt adhere to the material, deteriorating its appearance. Conventionally, antistatic methods for synthetic resins can be roughly divided into additive-kneading methods, which mainly use surfactants, and surface-coating methods, which mainly use silicone compounds, and some of these methods have been put into practical use. There are examples of practical application of additive kneading molds to acrylic resin molding materials, but there are still no examples of fully satisfactory performance achieved by applying additive kneading molds to acrylic resin molded products. I can't find it. In addition, as an example of surface coating type, it is known that treatment with silicone-based compounds is used, and although it has been put into practical use to some extent, it is costly due to the additional artificial treatment applied to the finished product. There are problems and it is difficult to say that it is common. In view of these circumstances, the present inventors have developed an excellent method using the cast polymerization method, which is a common manufacturing method for acrylic resins, without impairing the unique properties of acrylic resins. As a result of extensive research in order to obtain an acrylic resin composition with antistatic properties, we found that an acrylic resin composition can be obtained by using a complex ionic organic boron compound, a glycerin monofatty acid ester, and a quaternary alkyl sulfate. It was discovered that an acrylic resin composition having excellent antistatic performance can be obtained with a small amount of compounding without impairing the original physical properties, and the present invention was achieved. The antistatic method of adding a complex ionic organic boron compound alone to an acrylic resin was published in Japanese Patent Publication No. 48-43371.
Disclosed in the issue. However, it is not possible to obtain antistatic performance with a small amount of addition, and although antistatic performance can be obtained with a large amount, the polymerization rate is delayed during cast polymerization, and the resulting product has no voids. There were many occurrences, and the bleed phenomenon was significant, making the product unsatisfactory. In addition, the method of adding glycerin monofatty acid ester is an effective antistatic method, but the effective target resins are limited to soft polyvinyl chloride, low density polyethylene, polypropylene, etc., which have a low glass transition point. Even when added to acrylic resin, antistatic performance was not exhibited. On the other hand, even if a quaternary alkyl sulfate salt is added alone to an acrylic resin, antistatic performance cannot be obtained. A method of using a complex ionic organic boron compound and a glycerin monofatty acid ester, a method of using a complex ionic organic boron compound and an alkyl sulfate quaternary salt, and a method of using a glycerin monofatty acid ester and an alkyl sulfate quaternary salt together. In any of the antistatic methods, it is not possible to obtain antistatic performance with a small amount of addition, and if a large amount is added, antistatic performance can be achieved, but a delay phenomenon in the polymerization rate is observed during cast polymerization. However, the resulting product is not satisfactory as a product as there are many voids and the bleed phenomenon is significant. That is, the gist of the present invention is to create a composition having antistatic properties by adding and mixing a complex ionic organic boron compound, a glycerin monofatty acid ester, and a quaternary alkyl sulfate salt to an acrylic resin and using a cast polymerization method. In the method of manufacturing things,
Methyl methacrylate monomer alone, a mixture of methyl methacrylate and other monomers that can be copolymerized, or a partial polymer or copolymer thereof are simultaneously treated with the antistatic performance imparting agent, or The present invention relates to an acrylic resin composition having excellent antistatic properties, which is prepared by adding, mixing and dissolving a mixture of these materials, adding a polymerization initiator, and casting polymerization. The complex ionic organic boron compounds used in the present invention include bisglycerylborate monopalmitate, bisglycerylborate moreolate, bisglycerylborate monostearate, bisglycerylborate isostearate, and bisglycerylborate monohydroxystearate. are mentioned as preferred examples, and bisglyceryl borate monostearate is particularly effective. Moreover, these can be used alone or in combination of two or more types as required. The glycerin monofatty acid ester is a monoester of glycerin and a higher fatty acid having 8 to 22 carbon atoms, such as glycerin monolaurate, glycerin monomyristate,
Preferred examples include glycerin monopalmitate, glycerin monooleate, glycerin monostearate, glycerin monomontanate, glycerin monolinoleate, and glycerin monobehenate, with particular preference given to glycerin monostearate. Effective. Moreover, these can be used alone or in combination of two or more types as required. Examples of quaternary salts of alkyl sulfates include (3-lauramidepropyl)trimethylammonium methylsulfate, (3-stearamidepropyl)trimethylammoniummethylsulfate, (3-lauramidepropyl)dimethylethylammonium ethylsulfate, and (3-lauramidepropyl)dimethylethylammonium ethylsulfate. Preferred examples include dimethylethylammonium ethyl sulfate (stearamidepropyl) and the like. Suitable examples of the composition of the present invention include 0.3 to 5 parts by weight, preferably 0.5 to 4 parts by weight, and 0.1 to 5 parts by weight of a glycerin monofatty acid ester, based on 100 parts by weight of the acrylic resin. , preferably 0.3 to 4 parts by weight, and 0.1 to 0.5 parts by weight of the alkyl quaternary sulfate, preferably 0.2 to 0.3 parts by weight. Antistatic performance cannot be obtained if the complex ionic organic boron compound is added in an amount of less than 0.3 part by weight, the glycerin monofatty acid ester is added in an amount of less than 0.1 part by weight, and the quaternary alkyl sulfate salt is added in an amount of less than 0.1 part by weight. Furthermore, no improvement in antistatic performance was observed when the complex ionic organic boron compound was added in an amount of 5 parts by weight or more, the glycerin monofatty acid ester was added in an amount of 5 parts by weight or more, and the quaternary alkyl sulfate was added in an amount of 0.5 parts by weight or more. On the contrary, the obtained product has many voids, and is undesirable because it has noticeable discoloration, devitrification, and bleeding. The acrylic resin referred to in the present invention is polymethyl methacrylate alone or a copolymer of methyl methacrylate and other copolymerizable monomers.
Other copolymerizable monomers are not particularly limited, but in the present invention, acrylic esters having an alkyl group having 1 to 10 carbon atoms or methacrylic esters having an alkyl group having 2 to 18 carbon atoms, e.g. , methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, cyclohexyl acrylate, 2-hydroxyethyl acrylate, ethyl methacrylate, butyl methacrylate, 2-ethylhexyl methacrylate, lauryl methacrylate, methacrylic acid Stearyl, cyclohexyl methacrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate; acrylic acid, methacrylic acid,
Preferred examples include styrene, acrylonitrile, and methacrylonitrile. One or more of these can be used as a copolymer with methyl methacrylate. The conditions for producing the resin composition of the present invention are not particularly limited, and ordinary casting polymerization conditions for acrylic resins can be employed as they are. That is, a desired amount of a complex ionic organic boron compound, a glycerin monofatty acid ester, and a quaternary alkyl sulfate salt is mixed with a methyl methacrylate monomer or a methyl methacrylate monomer with another copolymerizable monomer. A mixture solution or a partial polymer or copolymer thereof, either simultaneously or in advance, is added together with a polymerization initiator, mixed and dissolved, and then poured into a desired mold,
After degassing under reduced pressure, heat at 70 to 90℃ for 2 to 4 hours, then 100 to 100℃.
By heating and curing the resin composition at 120° C. for 40 to 90 minutes, a molded article of the resin composition of the present invention having a desired shape can be obtained. The acrylic resin composition produced by the present invention has extremely excellent antistatic properties and is particularly effectively used for electrical equipment parts such as meter covers, nameplates, etc. of instruments. Further, in the present invention, known additives such as ultraviolet absorbers and various dyes/pigments can be used as necessary, and many of these can be used in combination without any side effects. Specific examples of the present invention are shown below, and parts in the examples indicate parts by weight. The antistatic performance was evaluated by measuring the resistance using a 60 mm x 60 mm x 3 mm sample using a super insulation resistance tester manufactured by Yokogawa Heuretsu Packard Co., Ltd. Examples 1 to 6 Bisglyceryl porate monostearate, glycerin monostearate, and (3-lauramidopropyl) trimethylammonium methyl sulfate were added and mixed in various proportions to 100 parts of methyl methacrylate monomer. After heating and dissolving at ℃, 0.012 part of α,α'-azobisisobutyronitrile was added as a polymerization initiator. This mixed solution was injected between two glass plates using a polyvinyl chloride tube as a gasket, and then heated at 86℃ for 3 hours.
It was polymerized and cured by heating at 120°C for 1 hour. After completion of polymerization, the plate is colorless and transparent, and has excellent antistatic properties immediately after being taken out.After rubbing strongly with a dry cloth,
No ash adhesion occurred even when it was brought close to dry ash. Also, place this board in an air oven at 200℃.
Even after heat treatment for 30 minutes, the antistatic performance did not change and the board itself did not change color. Table 1 shows the resistance measurement results. Comparative Examples 1 to 2 Examples 1 to 2 except that bisglyceryl borate monostearate and glycerin monostearate were added and mixed to 100 parts of methyl methacrylate monomer.
Polymerization was carried out by heating in the same manner as in 6. Although the plate after completion of polymerization was colorless and transparent, it did not exhibit antistatic performance unless it was incorporated in a large amount, and in this case voids and bleed occurred, making it impossible to use as a product. Table 1 shows the resistance measurement results. Comparative Examples 3 to 4 Heat polymerization was carried out in the same manner as in Examples 1 to 6 except that bisglyceryl borate monostearate was added and mixed alone to 100 parts of methyl methacrylate monomer. The plate after completion of polymerization was colorless and transparent, but since a large amount of additives were mixed, although it was able to exhibit antistatic performance, voids and bleeding occurred, and it could not be used as a product. Table 1 shows the resistance measurement results. Comparative Example 5 Heat polymerization was carried out in the same manner as in Examples 1 to 6 except that 10 parts of glycerin monostearate was added and mixed alone to 100 parts of methyl methacrylate monomer. After completion of polymerization, the plate was colorless and transparent, but did not exhibit antistatic performance. Table 1 shows the measured resistance values. Comparative Example 6 Heat polymerization was carried out in the same manner as in Examples 1 to 6 except that 1 part of (3-lauramidopropyl)trimethylammonium methyl sulfate was added and mixed alone to 100 parts of methyl methacrylate. After completion of polymerization, the plate not only did not exhibit antistatic properties, but also had voids, bleed, coloring, and even devitrification phenomena, and could not be used as a product. Table 1 shows the resistance measurement results.
