Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a novel method for manufacturing a colored vinyl chloride resin decorative article having an uneven three-dimensional colored pattern or figure on its surface.

[Prior Art] Traditionally, colored plastic decorations include:
A wide range of soft and hard plastics are commercially available, including animals, plants, vehicles,
Products of various shapes, such as landscape paintings and shaped fruits, are known. These colored plastic ornaments are made by punching colored plastic sheets into desired shapes, or by injection molding, compression molding, extrusion molding, etc. using molds of desired shapes. It is manufactured by a method of molding using heat, pressure, or both at the same time.

On the other hand, colored printed plastic sheets are commercially available as decorative items. This is a plastic sheet printed with, for example, a flower pattern, a seasonal pattern, etc. in a desired color.

In addition, brooches, pendants, earrings, etc. are commercially available as plastic accessories, but these are mainly made of plastic sheets printed with animal, plant, or other patterns, or punched into animal, plant, or other shapes, or A fastener is attached to the back side of a colored plastic sheet or the like that is molded with irregularities and is attached to clothing or the body.

[Problems to be Solved by the Invention] However, since ornaments manufactured using the conventional colored plastic materials as described above are produced by the mechanical molding method as described above, the shape depends on the mold. Because it is defined, it is uniform, and the color tone is often almost monochromatic, which has the disadvantage that it is impossible to produce a monotonous product.

On the other hand, decorative items made of colored printed plastic sheets lack a three-dimensional effect because the painted surface is flat, and the printing may peel off if rubbed too hard or used for a long period of time. There were some drawbacks.

Furthermore, like the above-mentioned ornaments, plastic accessories lack a three-dimensional effect because they have a flat surface, or even if the surface is uneven, the color tone is almost monochromatic, resulting in a low decorative effect. There were flaws.

The present invention was made in view of the conventional colored plastic ornaments as described above, and uses liquid colored vinyl chloride resin droplets of two or more colors to be cured and fused together. The object of the present invention is to provide a method for manufacturing a colored vinyl chloride resin decorative article having an excellent decorative effect and having a completely new surface colored in a desired color tone and having an uneven three-dimensional colored pattern or figure. It is.

[Means for Solving the Problems] and [Operation] That is, the present invention provides droplets of liquid colored vinyl chloride resin on a heating plate, and after the surface of the droplets is dried by heating, the following steps are performed. Droplets of liquid colored vinyl chloride resin are dropped in contact with and/or overlapping the droplets, and the process of drying the surface of the droplets is sequentially repeated to produce liquid colored vinyl chloride resin in two or more various colors. A decorative article made of colored vinyl chloride resin, which is characterized in that after forming an aggregate of resin droplets, the aggregate is heated to harden and fuse together, and then cooled and peeled off from a heating plate. This is the manufacturing method.

The present invention will be explained in detail below.

FIGS. 2a to 2d are process diagrams showing an example of the method for manufacturing the colored vinyl chloride resin ornament of the present invention. In the same figure, first, about
A heating plate is placed on a hot plate heated to 150 to 200°C, and droplets 1 of liquid colored vinyl chloride resin are dropped onto the heated heating plate (not shown). (See Figure 2a) In the present invention, the method of dropping droplets of the liquid colored vinyl chloride resin may be by extruding the liquid colored vinyl chloride resin from an extrusion tube and dropping it, or by dropping two or more drops of the colored vinyl chloride resin. In the case of dripping, an extrusion tube filled with liquid colored vinyl chloride resin of each color may be set, and the resin may be extruded from the extrusion tube and dripped all at once. Also,
When dropping resin, the amount and shape of one drop of resin are not particularly limited and can be arbitrarily determined depending on the purpose.

Next, after the dropped droplet 1 is heated by a heating plate and the surface is dried, four drops of the next liquid colored vinyl chloride resin droplet 2 are dropped around and in contact with the droplet 1. . (See Figure 2b) Furthermore, after the dropped droplet 2 is heated by a heating plate and its surface is dried, another liquid colored vinyl chloride resin droplet 2a is added to the droplet 1 and the droplet 2. Drop 4 drops so that they touch each other. (See Figure 2c) Next, after the dropped droplet 2a is heated by a heating plate and its surface is dried, an elongated droplet 3 of liquid colored vinyl chloride resin is added to the droplet 2, 2.
Two drops are dropped so as to be in contact with a to form a collection of droplets of liquid colored vinyl chloride resin in various colors. (See Figure 2 d) After that, the aggregate is sealed with a lid, and the temperature is raised to 200-220℃ and heated for 2-3 minutes until the surface of the resin becomes glossy. After curing the vinyl chloride resin and fusing it together,
By cooling the hardened colored vinyl chloride resin with water, etc. and peeling it off from the heating plate, it is formed into a flat surface with an uneven three-dimensional colored pattern or figure on the surface and a soft, flat back surface. Colored vinyl chloride resin ornaments can be obtained.

In the present invention, a first liquid colored vinyl chloride resin droplet is dropped onto a heating plate, the surface of the droplet is dried, a second droplet is dropped and dried, and then a third droplet and a third droplet are dried. 4. Dry the droplets in the same way and drop them so that they touch and/or overlap, so that in the resulting collection of droplets, the droplets of each color maintain clear outlines and form an uneven surface. , by changing the size of the droplets, the desired pattern or figure is clear and
You can obtain products with vivid colors.

The colored vinyl chloride resin ornament produced by the method described above can be used as it is as an ornament with excellent decorative effects.
