Description: TECHNICAL FIELD The present invention relates to a coloring agent particularly suitable for coloring a vinyl chloride resin. <Prior Art> In recent years, rationalization of production has become an important management issue for vinyl chloride resin compound processing manufacturers or vinyl chloride resin molding manufacturers. To this end, colorants, which are secondary materials but play a very important role in the value of the final molded article of vinyl chloride resin, are required to have various properties to be provided for rationalization. The characteristics are (a) automatic measurement for labor saving and automation, (b)
Non-scattering property for shortening color change time, non-contaminating property of container wall, and (c) low lubricity for easy processing and quality stabilization.
Examples include peptization / dispersibility and color development stability. There are various types of colorants for vinyl chloride resin in terms of form, but they are roughly classified into dry color, plate batch type, paste type, and powder type. <Problems to be solved by the invention> Since dry color is in the form of a fine powder, it is very scatterable, causing a deterioration in the workplace environment, and is not suitable for automatic weighing. No. A plate batch type colorant contains a large amount of a plasticizer and is often used in the field of soft vinyl chloride resin processing. However, since it is a plate, it is not suitable for automatic measurement. In addition, there is a problem in uniformity when mixed with a vinyl chloride resin or a compound. Paste type colorant is a high viscosity liquid,
It is difficult to handle, and the wall contamination of mixers such as Henschel mixer, Banbury mixer and ribbon blender is severe,
It is often used only as a coloring agent for vinyl chloride paste resins. The powder type coloring agent includes a powdery wet type using a polyethylene wax as a vehicle, and a powdery resin dispersed type using a styrene-acrylic resin or a vinyl chloride resin as a vehicle. The wetting type colorant has a small scattering property and also has an automatic weighing property, so that it has a wide range of use and occupies the mainstream of the colorant. However, there were problems such as severe contamination in the mixer, unstable color development, and lubricity, which made molding difficult when used in large quantities. Further, recently developed resin-dispersed type colorants have improved problems such as non-staining property, color development stability, and low lubricity. However, because the main vehicle is a resin with a fluid softening point of 150 ° C or higher, there is a problem in peptization and dispersibility (easiness of unraveling when added to vinyl chloride resin and compound and heated and kneaded). The agent is dispersed in the molded product as it is unraveled, causing fish eyes and pinholes. Therefore, it has not been able to satisfy all market requirements. For example, a colorant described in JP-A-56-55446 is one example of such a colorant, which is a high softening point of an acrylic-styrene copolymer containing styrene as a copolymerization component in a main vehicle. Because of the use of the material, the kneading properties in the low temperature range are poor, and still need improvement. <Means for Solving the Problems> The present inventors have conducted intensive studies in view of such a situation, and as a result, have added a vinyl chloride resin to a specific (meth) acrylate resin as required. Using the resin component as a vehicle, adding a pigment and a plasticizer to this, and further using a coloring agent obtained by adding a wax, a stabilizer, and the like as needed, eliminates the above-mentioned problems, and provides a vinyl chloride resin. It has been found that a colored vinyl chloride-based resin having good compatibility with water and excellent transparency can be obtained, and the present invention has been completed. That is, the present invention relates to a resin component composed of 20 to 100% by weight of a (meth) acrylate resin having a flow softening point of 90 to 150 ° C and 0 to 80% by weight of a vinyl chloride resin (total 10%).
0% by weight) and a pigment and a plasticizer. The (meth) acrylate resin used in the present invention includes methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, and (meth) acryl. A resin obtained by polymerizing one or more of (meth) acrylate monomers such as lauryl acid as a main component, and further adding (meth) acrylic acid as needed, and having a fluid softening point. And those having a fluid softening point of 110 to 130 ° C are preferred. The flow softening point is measured as follows. A very small amount (0.001) between 20 mm x 20 mm glass plates (1 mm thick)
A sample in which a sample powder (about 0.002 g) is sandwiched is placed in a microscope, and the sample is heated at a rate of 20 ° C./min while irradiating light from below. When the temperature near the softening point is reached, a force of about 500 g / cm 2 is applied to the sample with tweezers or the like, and the colorant softens and dissolves to form a film, and when light from below is blocked by the film-like colorant, The temperature is measured and taken as the flow softening point. As the vinyl chloride resin used as required in the present invention, a homopolymer of vinyl chloride or vinyl chloride may be used.
Resins obtained by copolymerization as components, for example, vinyl chloride-vinyl acetate copolymer resin, vinyl chloride-ethylene copolymer resin, vinyl chloride- (meth) acrylate copolymer resin and the like, among which the average polymerization degree = Those having a low polymerization degree of 1000 or less are preferred in that the fluid softening point is low. The proportion of the (meth) acrylate resin and the vinyl chloride resin used as the resin component in the present invention is such that the (meth) acrylate resin is usually 20 to 100% by weight based on the total amount of 100% by weight, Preferably 50-80% by weight,
The content of the vinyl chloride resin is usually in the range of 80 to 0% by weight, preferably 50 to 20% by weight. As the pigment used in the present invention, any pigment for coloring a synthetic resin can be used. For example, organic pigments such as azo-based, phthalocyanine-based, quinacridone-based, and sulene-based pigments, titanium oxide, carbon black, iron oxide, and graphite can be used. Examples include inorganic pigments and extender pigments such as calcium carbonate and barium sulfate. As the plasticizer used in the present invention, any plasticizer for a vinyl chloride resin can be used, for example, di-2-phthalic acid.
Phthalate plasticizers such as ethylhexyl (DOP), linear dibasic ester plasticizers such as di-2-ethylhexyl adipate (DOA), epoxy plasticizers such as soybean oil with epoxy value, and adipic polyester And polyester plasticizers. The ratio of the resin component, the pigment and the plasticizer used is usually 100 parts by weight based on the total amount of these three components and one resin component.
0-80% by weight, pigment 10-80% by weight, plasticizer 3-50% by weight
Range. Among them, when an organic pigment is used, the resin component is preferably in a range of 30 to 60% by weight, a pigment is used in a range of 30 to 60% by weight, and a plasticizer is used in a range of 5 to 20% by weight. A range of 30% by weight, a pigment of 50 to 80% by weight, and a plasticizer of 5 to 20% by weight is preferable. The colorant of the present invention contains the above-mentioned resin component, pigment and plasticizer as essential components. If necessary, a wax, a stabilizer, other resins and the like can be added. As the wax, hydrocarbon-based, fatty acid-based, paraffin-based, and ester-based waxes can be used, and the amount of the wax is usually in the range of 15% by weight or less in the colorant. 5% by weight for low lubricity
It is preferable to set the following. As the stabilizer, any of known stabilizers such as various metallic soaps, organic tin compounds and basic lead compounds can be used. The coloring agent of the present invention is, for example, a predetermined amount of a resin component, a pigment,
After mixing and stirring the plasticizer, wax, stabilizer and the like with a mixer, the mixture is obtained by kneading with a kneader such as a pressure kneader or a heating roll.In a usual case, a lump obtained by kneading is obtained by a pulverizer. Pulverized, classified, and used as a powdered colorant having a uniform particle size. The flow softening point of the coloring agent of the present invention thus obtained is usually
The temperature is 90 to 120 ° C, and among them, the one having a temperature of 100 to 110 ° C is preferable. <Example> Hereinafter, the present invention will be described specifically with reference to Examples and Comparative Examples. All parts in the examples are parts by weight. Example 1 70 parts of methyl methacrylate-butyl acrylate copolymer resin (flow softening point 125 ° C.) and vinyl chloride resin (
