The present invention relates to an antistatic agent for resins used in molding resin compositions and paper coatings. Calcium carbonate powder is widely used as a filler for resins for the purpose of improving the dimensional stability, heat resistance, flame retardance, rigidity, etc. of various resin molded products, and for the purpose of reducing costs. It is also used as a filler in paper paints. By the way, in the case of resin molded products and coated paper, it prevents the adhesion of dust by preventing static electricity, and in the case of computer flooring and packaging, it prevents computer malfunctions due to static electricity, and in the case of dry copy paper, paper Efforts are being made to make feeding smoother. Such antistatic methods include conventional methods of adding an appropriate antistatic agent to resin molding compositions and paper coatings;
Alternatively, methods of forming a thin film of conductive resin on the surface of a resin molded product or paper are known, but in either case, fully satisfactory results have not been obtained. There was a concern that the antistatic effect deteriorated over time. As a result of intensive studies in light of the above circumstances, the inventors performed a specific surface treatment on calcium carbonate powder, which is commonly used as a filler for resins, and used this as the filler to form resin compositions for molding. The present invention was completed based on the discovery that when added to paper paints and the like, it is possible to effectively prevent the resulting resin molded product or coated paper from becoming electrostatically charged. That is, this invention has the following general formula; [In the formula, R 1 is hydrogen or

[Formula] R 2 is hydrogen or a methyl group, R 3 is an alkyl group having 10 to 22 carbon atoms, and n+m is an integer of 1 to 15] A resin made of calcium carbonate powder surface-treated with a polyoxyalkylene amine compound represented by This relates to antistatic agents. In this invention, the polyoxyalkylene amine compound represented by the above general formula used for surface treatment of calcium carbonate powder includes various commercially available alkyl polyoxyalkylene amines, and one or more of them may be used. It will be done. The above-mentioned polyoxyalkylene amine compound gives good results in preventing static electricity on molded products or coated paper even when it is added directly to molding resin compositions or paper coatings, but when the surface is treated with this compound, By using calcium carbonate powder, the molded article or coated paper can be further prevented from being charged. Note that the reason for this is not necessarily clear at present. Surface treatment is generally carried out by adding the above-mentioned polyoxyalkylene amine compound to calcium carbonate powder while stirring the powder at 110 to 120° C. with a high-speed mixer. The amount of polyoxyalkylene amine compound added is calcium carbonate powder 100
It is usually about 0.5 to 5 parts by weight. By using the calcium carbonate powder surface-treated by the above method as a filler for resins such as polyvinyl chloride resin, polyolefin resin, polyester resin, etc. or as a filler for paper paint, the untreated calcium carbonate powder can be used as a filler for filling the above-mentioned method. Insulation resistance of molded products or coated paper is lower than when untreated calcium carbonate powder and the polyoxyalkylene amine compound are added simultaneously to molding compositions or paper coatings. Significantly decreased. Further, as the original function of calcium carbonate powder, it is possible to improve the dimensional stability, heat resistance, flame retardance, and rigidity of molded products or coated paper, and furthermore, good results can be obtained in cost reduction. Hereinafter, the present invention will be explained in more detail by describing examples. Note that in the following, parts mean parts by weight.

The mixture was heated to 110-120°C while stirring with a high-speed mixer, and an alkyl polyoxyalkylene amine (in the general formula, R 3 is a stearyl group, R 1 is a polyoxyethylene group, R 2 is hydrogen, and n+m is 7)4
By adding 50% of the mixture and continuing heating and stirring for an additional 5 minutes, surface-treated calcium carbonate powder was obtained. 250 parts of this treated powder, 100 parts of polyvinyl chloride resin (high quality 103EP manufactured by Nippon Zeon Co., Ltd.), 50 parts of dioctyl phthalate, 1 part of barium stearate and 1 part of zinc stearate were mixed and heated at 160 to 165°C. After kneading, a sheet molded product with a thickness of 2.0 mm was produced by press molding at 170°C. The results of investigating the volume resistivity values of this sheet molded product at the initial stage (5 hours after press molding) and after storage over time (5 days using a weatherometer at 20°C and 42% RH) are as shown in Table 1 below. It was hot. In addition, Comparative Example No. 1 in the table is the result of a sheet molded product produced in the same manner as above except that the untreated calcium carbonate powder according to the example was used, and No. 2 is the result of the above No.
A conductive resin composition (an organic solvent with a solid content of 30% by weight made by dissolving a quaternary ammonium salt type acrylic polymer in a mixed solvent of isopropyl alcohol and xylene at a weight ratio of 4:6) was applied to the surface of the sheet molded product No. 1. Solution) was applied at a rate of 1 g/ m2 , and No. 3 was obtained by adding and mixing the untreated calcium carbonate powder according to Example 1 and the alkyl polyoxyalkylene amine into the resin composition at the same time. These are the results of a sheet molded product produced in the same manner as above, except that.
