The present invention relates to a fine powder colorant composition for polyvinyl chloride paste. More specifically, the present invention relates to a fine powder colorant composition for polyvinyl chloride paste containing a pigment, an inorganic filler, and one or more polyethylene glycol fatty acid ester surfactants. Polyvinyl chloride resin (hereinafter abbreviated as PVC) obtained by emulsion polymerization and called paste resin is suspended and dispersed in a liquid plasticizer for PVC with simple stirring, and forms a fluid paste. This is called a ``plastisol,'' and a paste resin suspended and dispersed in a liquid plasticizer for PVC and an organic solvent is called an ``organosol.'' These are collectively called PVC paste. These "plastisols" and "organosols" have fluidity at room temperature and become homogeneous and elastic solids when heated. The PVC paste processing method takes advantage of this property. The coloring agent used in PVC paste processing is usually in the form of a paste, which is made by mixing and dispersing pigments and PVC plasticizers that are liquid at room temperature using three rolls. This pasty colorant is highly sticky, making it inconvenient to handle, making it difficult to dispose of contaminated containers after using the colorant, and causing problems such as separation of the pigment and PVC plasticizer during long-term storage. There are drawbacks. On the other hand, powdered colorants have the advantage of being convenient to handle, but pigments as they are or conventional powdered colorants have poor dispersibility in PVC paste, thickening properties,
In reality, it could not be used due to problems such as defoaming properties. For example, finely powdered titanium oxide, which is added in large amounts in paste resin processing, is sometimes added to PVC paste in its unprocessed state and kneaded and dispersed using a triple roll, but this kneading and dispersion process requires a long time. be. In view of the above-mentioned drawbacks, the inventors of the present invention have conducted intensive studies to obtain a colorant that has good dispersibility, does not thicken, is convenient to handle, and does not change over time during storage. By uniformly mixing and pulverizing one or more polyethylene glycol fatty acid ester surfactants,
The present invention was completed based on the discovery that not only the dispersibility, diffusibility, and thickening properties of pigments in PVC paste were improved, but also a fine powder colorant composition that was convenient to handle and did not change over time could be obtained. . That is, the gist of the present invention is a fine powder colorant composition for PVC paste, which is formed by uniformly mixing a pigment, an inorganic filler, and one or more polyethylene glycol fatty acid ester surfactants. The pigment used in the present invention is preferably an inorganic pigment, which has an average particle size of 2.5 microns or less.
Any material suitable for coloring PVC can be used successfully. For example, anatase titanium oxide, rutile titanium oxide, Bengara, yellow iron oxide, iron black, chromium oxide,
Examples include ultramarine blue, chrome yellow, chrome vermilion, etc., and their content in the fine powder colorant composition is preferably 40 to 90 percent by weight, preferably 60 to 80 percent by weight. The inorganic fillers used in the present invention include, for example, calcium carbonate, clay, silica, calcium silicate, magnesium silicate, mica, diatomaceous earth, etc., and these have an average particle size of 3 microns or less and an oil absorption capacity (DOP). It is preferable that the amount is 60ml/100g or less. These inorganic fillers may be surface-treated or non-surface-treated, but surface-treated ones are preferable.The content of the inorganic filler in the fine powder colorant composition is 5 to 5.
60% by weight, preferably 10-40% by weight. The polyethylene glycol fatty acid ester surfactants used in the present invention include polyethylene glycol fatty acid ester compounds, polyethylene glycol dialiphatic carboxylic acid ester compounds, and derivatives thereof, and one or more of these may be used alone or in combination. used in The polyethylene glycol fatty acid ester compound is preferably an ester compound of polyethylene glycol with a molecular weight of 1000 or less and a fatty acid with a carbon number of 8 to 32. Examples include polyethylene glycol monooleate, polyethylene glycol monolaurate, and polyethylene glycol monopalmide. tate, polyethylene glycol monoricinolate, etc. Furthermore, polyethylene glycol dialiphatic carboxylic acid ester compounds and their derivatives are preferably ester compounds of polyethylene glycol with a molecular weight of 1000 or less and dialiphatic carboxylic acids such as maleic acid and succinic acid. Examples include ester compounds of dialiphatic carboxylic acids into which an alkyl group or a sulfone group has been introduced, and their sodium salts. Examples include polyethylene glycol monooctyl maleate, polyethylene glycol monooctyl sulfomaleate and its sodium salt, polyethylene glycol monooctyl succinate, polyethylene glycol monooctyl sulfosuccinate and its sodium salt. Polyethylene glycol fatty acid ester compounds, polyethylene glycol dialiphatic carboxylic acid esters, and their derivatives have great effects when used alone, but when used in combination, they have a synergistic effect that improves PVC in fine powder colorant compositions.
Polyethylene glycol fatty acid ester compounds not only improve dispersibility and diffusivity in pastes but also inhibit the thickening of PVC pastes and improve cell uniformity during foaming.Polyethylene glycol fatty acid ester compounds have a large viscosity-reducing effect. , and polyethylene glycol dialiphatic carboxylic acid ester compounds and their derivatives.
Great effect on cell uniformity when foaming PVC paste. In general, when surfactants are added to PVC pastes, they do not soften the product like plasticizers do, they do not volatilize like diluting solvents, and they have a viscosity-reducing effect that helps pigment dispersibility and diffusion. However, depending on the type, it may have poor compatibility with PVC paste, resulting in negative effects such as blooming, thickening, and impairing thermal stability. On the other hand, if a large amount is contained in a fine powder colorant composition, the colorant tends to form blocks, and the dispersibility into the PVC paste may be impaired. For the above reasons, the content of the surfactant of the present invention in the fine powder colorant composition is usually 0.01 to 5% by weight, preferably 0.5 to 3% by weight. When polyethylene glycol fatty acid ester, polyethylene glycol dialiphatic carboxylic acid ester, and its derivatives are used together, the mixing ratio thereof is preferably 10:90 to 90:10. In addition, in order to prevent the fine powder colorant from scattering and to improve its affinity with the PVC paste, a PVC plasticizer may be added within a range that does not solidify the colorant. Furthermore, heat stabilizers, ultraviolet absorbers, ultraviolet stabilizers, optical brighteners, flame retardants, etc. can be added depending on the processing conditions of the PVC paste and the intended use of the product. The present invention will be explained below using Examples and Comparative Examples. Examples 1 to 5 and Comparative Example 1-7 According to the recipe in Table 1, the inorganic filler was put into a Henschel mixer (manufactured by Mitsui Miike Seisakusho), and while stirring, the surfactant was gradually added and mixed for 3 minutes. do.
Next, add the inorganic pigment and mix it uniformly for 3 minutes, then take it out.
The mixture was mixed and ground using a fine grinder equipped with a screen having a diameter of 1 m/m to obtain a fine powder coloring agent for PVC paste.
However, Comparative Examples 3 and 7 are paste coloring agents kneaded and dispersed using three rolls.

遜色がない事が判明した。[Table] The colorants obtained in Examples and Comparative Examples were evaluated for storage stability, dispersibility, change in viscosity of PVC paste, and uniformity of foam cells according to the following methods. Storage stability of colorant The colorant was stored at room temperature for 2 months, and changes in the appearance of the colorant were visually judged. Dispersibility PVC (paste resin) 100 parts by weight, liquid stabilizer (Ca-Zn) 3 parts by weight, blowing agent (azodicarbamide) 5 parts by weight, DOP 60 parts by weight, calcium carbonate 40 parts by weight, and petroleum diluent solvent 4 parts by weight Take 100 parts by weight of the PVC paste, add 10 parts by weight of each coloring agent, and stir and disperse at 600 rpm using a lab mixer (Model LA-30 manufactured by Tokushu Kika Kogyo Co., Ltd.). It was applied on a glass plate at minute intervals, and the time (minutes) until streaks and aggregates of the colorant were no longer observed was measured. Change in viscosity of colored PVC paste Using each colored PVC paste obtained using the same formulation and procedure as above, the viscosity was measured using a BL viscometer 1 hour and 48 hours after sample preparation.
However, the amount of DOP in the powdered colorant was adjusted to be the same as in Comparative Examples 3 and 7. Uniformity of foam cells. Viscosity measured after 48 hours using colored PVC paste applied to wallpaper at a thickness of 10 mils with an applicator.
The mixture was gelatinized at 130°C for 30 seconds and then foamed at 210°C for 60 seconds, and the appearance of the foamed cells was observed using a magnifying glass (15x magnification). The evaluation results are summarized in Table-2. The handling convenience of the powdered colorant of the present invention was better than that of the paste colorant without any need to measure it. Storage stability has been completely improved and
It was confirmed that the viscosity of the PVC paste sol did not increase and the change in viscosity over time was small. It was found that the dispersibility of the colorant and the uniformity of the cells during foaming of the colored paste sol were comparable to those of the paste colorant.
