Abstract

PURPOSE:To obtain a pattern with external appearance of natural beauty by a method wherein the required quantity of different color extruded precolored resin composition pats from sub-extruders, the delivery rate of each of which is variable and a necessary number of which are arranged on the kneading part of a main extruder, are added to the required positions of a main extruded precolored resin composition part. CONSTITUTION:Green kneaded mixture 1 consists in kneading 20pts.wt. of unsaturated polyester resin, 20pts.wt. of styrene monomer, 1pt.wt. of dicumyl peroxide, 10pts.wt of glass fibers, 46pts.wt. of calcium carbonate, 1pt.wt. of zinc stearate, 2pts.wt. of green coloring agent by means of a kneader. Black kneaded mixture 2 consists in kneading the mixture of the same composition as that of the green kneaded mixture except that the green coloring agent is changed by black coloring agent. 95pts.wt. of the green kneaded mixture 1 is charged and further kneaded in a single extruder. 5pts.wt. of the black kneaded mixture 2, which is divided into a necessary number of single extruders at the center of the kneading part of said single extruder. The divided black kneaded mixtures 2 are continuously added to the green kneaded mixture 1 extruded from the single extruder. The resultant delivered part is cut into the required weight in order to obtain molding material with pattern. A molded ash tray is obtained by compression-molding said molding material with pattern at the mold temperature of 155 deg.C and mold pressure of 150kg/cm<2>.

単調な模様にならざるを得なかった。Conventionally, patterned molding materials similar to natural stone have been produced by mixing crushed mineral products, hardened molding material pieces, crushed wood products, and cloth fragments into the molding material to create patterned molding materials and molding them to create patterns. Although molded products were obtained, in each method, the amount of patterning was uniformly dispersed in the molding material, so the molded products had no choice but to have a monotonous pattern.

する。In the present invention, a required number of sub-extruders with a variable extrusion amount are installed in the mixed line part of the main extruder, and the different colored resin composition extrudates from the sub-extruders are placed at the required positions of the main colored resin composition extrudates. Since this is a method for manufacturing a patterned molding material characterized by adding the required amount, the pattern is uniformly dispersed in the molding material and does not become a monotonous pattern, making it possible to obtain a pattern with a natural and beautiful appearance. The present invention will be described in detail below.

本発明を実施例にもとすいて説明する。The resins of the extruded colored resin composition used in the present invention include unsaturated polyester YVM resin, urea resin, melamine resin,
Although any thermosetting resin such as phenol resin can be used, it is preferable to use unsaturated polyester μ resin which has excellent transparency and colorability. In addition to the resin and necessary coloring agents, curing agents, catalysts, fillers, reinforcing agents, mold release agents, solvents, salts, etc. may be added as necessary. As the extruder, a single extruder or a multi-screw extruder can be used, and there are no particular limitations. However, as for the sub-extruder, it is better to use a small-capacity extruder than the main extruder because the degree of variation in the extrusion amount can be adjusted. This is easy and desirable. The required number of sub-extruders can be arranged from one to a plurality of sub-extruders, and the position of the sub-extruder may be any part of the main extruder where the lines are mixed, preferably near the middle of the line where the lines are mixed, but there are no particular limitations. It's not. The present invention will be explained below using examples.

, styrene monomer mountain, 1 part of dicumyl peroxide, 10 parts of glass fiber, 1 part of acidic acid, 1 part of zinc stearin, and 2 parts of green colorant were mixed in a kneader, then put into a single extruder and kneaded. At the same time, a black kneaded material obtained by processing in the same manner as the green mixed material except that the green coloring agent of the green mixed material 1 was changed to a black coloring agent was placed in a single extrusion ring with a variable extrusion amount arranged in the center of the mixed wire part. A patterned molding material was obtained by continuously adding 5 parts by weight of 2 to 95 parts by weight of the green kneaded product and cutting the extruded amount to the required weight. Next, the patterned molding material was molded at a mold temperature of 155°C and a molding pressure of 15°C.
