[Industrial Application Field] The present invention relates to a polypropylene resin composition that has excellent pigment dispersibility and product appearance in colored molded products. [Prior Art] Polypropylene resin has traditionally been used for industrial parts, due to its excellent chemical, physical and electrical properties.
It is widely used in the field of electrical appliance parts, and many of its products are colored. The coloring method involves mixing polypropylene resin with various stabilizers, fillers, etc. if necessary, and then adding pigments to make colored pellets, which are then used to mold the product. A method of making a masterbatch pellet of pigment and mixing it with polypropylene resin during molding to form a colored product (masterbatch method); There are methods (dry color method, liquid color method) in which products are molded in a state covered with pigments, and the last dry color method and liquid color method are increasingly being used because they are cost-effective. [Problems to be solved by the invention] In this case, the cost is lower than that of the dope dyeing method and the master batch method, but depending on the shape of the product, pigment dispersion may be poor and color unevenness may often occur in the product. In addition, this method also has the disadvantage that weld lines are more noticeable than in other methods. In order to solve these drawbacks, pigments are
Various metal soaps, waxes, etc. are added as dispersants, but their improvement effects are small;
Furthermore, even if the amount added is increased, there is a limit to the improvement effect, and the current situation is that a complete solution has not been reached. [Means for Solving the Problems] As a result of intensive research, the present inventors found that when molding colored products using the dry color method or liquid color method, the polypropylene resin used usually contains a dispersant for pigments. By selecting two or more specific types from the metal soaps used and adding them in predetermined amounts, the dispersibility of pigments during molding can be dramatically improved, resulting in a very good coloring state and a close weld line. The inventors have discovered that it is possible to obtain a product that is less noticeable, leading to the present invention. That is, the present invention uses polypropylene resin 100
parts by weight, 0.05 to 0.5 parts by weight of calcium stearate, and 0.05 parts by weight of one or more metal stearates selected from zinc stearate, magnesium stearate, and amminium stearate.
A colored polypropylene resin composition comprising ~0.5 parts by weight and a pigment. In the present invention, the polypropylene resin used is propylene homopolymer, ethylene-propylene copolymer, or propylene and other α-
It refers to a copolymer with olefin, including various polyethylenes, other crystalline resins, and various rubbers (EPR,
EPDM, etc.) and various inorganic organic fillers may be added, and if necessary, it may be partially or completely modified with an unsaturated carboxylic acid such as maleic anhydride. In addition to the composition of the present invention, additives such as various antioxidants, antistatic agents, and ultraviolet absorbers may be added as necessary. The amount of calcium stearate used in the present invention and the amount of one or more metal stearates selected from zinc stearate, magnesium stearate, and aluminum stearate are based on 100 parts by weight of the polypropylene resin.
Each must be in the range of 0.05 to 0.5 parts by weight,
If the amount of each added is less than 0.05 part by weight, the improvement effect of the present invention will be small, and if added in excess of 0.5 part by weight, each will stand out on the surface of the product, deteriorating the appearance of the product, which is not preferable in either case. Additionally, calcium stearate is usually added to polypropylene as a neutralizing agent for catalyst residue, but in order to obtain the effects of the present invention,
It is essential to blend a certain amount of calcium stearate and one or more metal stearates selected from zinc stearate, magnesium stearate, and aluminum stearate; no matter how much calcium stearate is blended, the The effect of the invention cannot be obtained. Hereinafter, the present invention will be specifically explained with reference to Examples. Example 1 Ethylene content 12.5% by weight, boiling n-heptane insoluble content 78.8% by weight, melt index 42g/
100 parts by weight of ethylene propylene block copolymer (hereinafter abbreviated as PP-A), 0.2 parts by weight of calcium stearate, zinc stearate
0.15 parts by weight, 0.05 parts by weight of 2,6-di-t-butyl-4-methylphenol, 0.1 parts by weight of tetrakis[methylene-3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate]methane After mixing the two parts using a Henschel mixer, they were pelletized using a 40 mmφ single-screw extruder. 100 parts by weight of these pellets were added with a red powder pigment (PV manufactured by Hoechst).
Fast Red B) 0.5 parts by weight was sprinkled on the test piece 1 (gate 3.5 mmφ) with a length of 240 mm, width of 80 mm, and thickness of 2 mm using an injection molding machine.
Test piece 2 (gate 3 mm x 1 mm) with two holes of 25 mm in diameter centered at mm was formed. The quality of the weld lines was visually inspected. The results are shown in Table-1. (1) Pigment dispersibility judgment criteria ○ Color unevenness due to poor pigment dispersibility Not at all △ 〃 Slightly present × 〃 Considerably present (2) Appearance ○ Embossed stearate None △ 〃 Slightly present × 〃 Considerably present (3) Weld line Judgment criteria ○ Weld line Almost inconspicuous △ 〃 Slightly noticeable × 〃 Quite noticeable Example 2 In Example 1, the amount of calcium stearate added was 0.1 part by weight, and the amount of zinc stearate added was
The test was conducted in the same manner as in Example 1, except that the amount was 0.1 part by weight. The results obtained are shown in Table-1. Example 3 In Example 1, the amount of calcium stearate added was 0.4 parts by weight, and the amount of zinc stearate was changed to 0.4 parts by weight.
The test was conducted in the same manner as in Example 1, except that the amount was 0.45 parts by weight. The results obtained are shown in Table-1. Example 4 In Example 1, instead of PP-A, an ethylene-propylene random copolymer (hereinafter referred to as PP Example 1 except that -B) was used.
It was tested in the same way. The results obtained are shown in Table-1. Examples 5 and 6 In Example 1, instead of zinc stearate,
The test was conducted in the same manner as in Example 1, except that magnesium stearate and aluminum stearate were used. The results obtained are shown in Table-1. Comparative Example 1 A test was carried out in the same manner as in Example 1 except that zinc stearate was not added. The results obtained are shown in Table-1. Comparative Example 2 A test was conducted in the same manner as in Comparative Example 1, except that the amount of calcium stearate added was 1.0 parts by weight. The results obtained are shown in Table-1. Comparative Example 3 In Example 1, the amount of calcium stearate added was 0.03 parts by weight, and the amount of zinc stearate added was 0.03 parts by weight.
The test was conducted in the same manner as in Example 1, except that the amount was 0.03 parts by weight. The results obtained are shown in Table-1. Comparative Example 4 In Example 1, the amount of calcium stearate added was 0.6 parts by weight, and the amount of zinc stearate was changed to 0.6 parts by weight.
The test was conducted in the same manner as in Example 1, except that the amount was 0.6 parts by weight. The results obtained are shown in Table-1.
