The present invention relates to a thermoplastic resin sheet containing germanium and tourmaline, and more particularly, germanium, which is a natural ore capable of coloring a mixture of a polyvinyl chloride (PVC) resin and a foaming paste polyvinyl chloride (PVC) resin. It relates to a thermoplastic resin sheet containing germanium and tourmaline, characterized in that the background color of the thermoplastic resin sheet prepared by adding a mixed powder of and tourmaline can exhibit a natural and luxurious color.

Generally, accessories such as hats, bags, footwear, jewelry, and dress accessories or portable electronic products such as cameras and tape recorders have been the standard of judgment for consumers to purchase based on the performance and price of products. As the performance of all the products, such as and the like are excellent, and the price difference between the products of the same type does not vary much, the consumer's purchasing criterion is based on the appearance of the product itself or the shape of the case design to protect the product. The judgment is an important factor, but the accessories or accessories such as hats, bags, shoes, jewelry, etc. are imprinted or printed on the outside of the case of electronics such as cameras and tape recorders. Label is shown in the photo of FIG. As the background (1) color of the label appears as the color of the pigment added to the synthetic resin raw material mixture, the color is not natural, and because it cannot express a high-quality atmosphere, Due to unnaturalness, there is a fear that problems may occur that are not properly valued.

Therefore, the present invention is to solve the above problems, a natural ore that can give color to the mixture of polyvinyl chloride (PVC) resin and polyvinyl chloride (PVC) resin for foaming of grayish white germanium and black brown By manufacturing a thermoplastic resin sheet by adding a mixed tourmaline powder, the mechanical properties such as tensile strength and elongation of the thermoplastic resin sheet are excellent, and the base color of the thermoplastic sheet is an artificial color of the chemical pigment. Germanium and tourmaline are separated from the atmosphere of natural minerals, and the color of the thermoplastic sheet is made to feel the luxurious atmosphere by the subtle color atmosphere that comes from the natural stone of germanium and tourmaline mixed powder which is natural ore. To provide a thermoplastic resin sheet containing the purpose All.

The thermoplastic resin sheet of the present invention for solving the above problems is 19 to 20% by weight of polyvinyl chloride (PVC) resin, 35 to 40% by weight of polyvinyl chloride (PVC) resin for foaming, 32 to 35% by weight of plasticizer 4 to 6% by weight of germanium and 4 to 6% by weight of tourmaline are added to the mixture, and 0.5 to 1.0% by weight of blowing agent and 0.5 to 1.0% by weight of stabilizer are prepared.

The thermoplastic resin sheet according to the present invention may be used as a household material such as labels, stationery cases, cushions, pillows, or building materials such as decorative sheets.

In addition, the polyvinyl chloride (PVC) resin used in the present invention plays a role of making the thermoplastic sheet exhibit soft characteristics by a plasticizer as a main raw material, and the mixing amount of the polyvinyl chloride (PVC) resin is 18 to 20% by weight. desirable. When the amount of polyvinyl chloride (PVC) resin is less than 18% by weight, the amount of mixing of other compound components is relatively high, which may lower mechanical properties such as tensile strength and elongation of the thermoplastic resin sheet. When it exceeds%, since foaming paste content of polyvinyl chloride (PVC) resin becomes small relatively, there exists a possibility that the foamability of a thermoplastic resin sheet may fall.

The foaming paste polyvinyl chloride (PVC) resin serves to excellent the elastic force of the thermoplastic resin sheet, the mixing amount is preferably 35 to 42% by weight. When the mixing amount of the polyvinyl chloride (PVC) resin for foaming is less than 35% by weight, the elastic force of the thermoplastic sheet may be lowered. When it exceeds 42% by weight, the elastic force of the thermoplastic sheet is increased but printing is performed. There is a risk of deterioration. The foaming paste polyvinyl chloride (PVC) resin used in the present invention preferably has a polymerization degree of 1,550 ± 50 and a Brookfield viscosity (DOP 60 phr) of 5,500 ± 2,000 cps (25 ° C). It is excellent in the stamping performance for engraving various patterns on the thermoplastic resin sheet within the range of the physical properties.

The plasticizer weakens the attraction between the chain polymers of the resins when molding the mixture of the polyvinyl chloride (PVC) resin and the foaming paste polyvinyl chloride (PVC) resin to soften the soft and soft properties of the thermoplastic resin sheet. It serves to make the, and the mixing amount is preferably 32 to 35% by weight. If the amount of the plasticizer is less than 32% by weight, there is a concern that the properties of the thermoplastic resin sheet may not be soft or soft, and if it is more than 35% by weight, the thermoplastic resin sheet does not exhibit sufficient softness. Only the surface of the thermoplastic resin sheet surface is so soft that it may interfere with printing or the printed figure may be easily damaged. The kind of plasticizer usable in the present invention is preferably selected from dioctyl phthalate (DOP) or dibutyl phthalate (DBP).

Germanium, which is a natural ore used in the present invention, is an off-white natural color and tourmaline having a natural color of blackish brown, red or green color and tourmaline having a blackish brown, red or green color when mixed with an appropriate amount. Because it plays a role, it is characterized in that the color of the base immediately after the manufacture of the thermoplastic resin sheet has a feeling of luxury atmosphere as if used for a long time clean. The mixing amount of germanium is preferably 4 to 6% by weight. When the mixing amount is less than 4% by weight, the atmosphere effect of the natural color of tourmaline may be lowered. When the mixing amount is greater than 6% by weight, There is a concern that the color of tourmaline may not be sufficiently expressed because the amount of germanium is relatively high compared to the amount of mixture.

Tourmaline used in the present invention serves to give the natural color of the natural color of the background color of the thermoplastic resin sheet, it will have each color such as black brown, red or green. If the amount of tourmaline is less than 4% by weight, the background color of the thermoplastic sheet may not sufficiently represent the color of the natural stone. If the amount of the tourmaline is more than 6% by weight, the amount of germanium is relatively high compared to the amount of germanium. There is a fear that the atmospheric effect of color is lowered.

The germanium powder and the tourmaline powder used in the present invention can be used by minimizing the volume of the powder particles while maintaining the properties of natural stone by using a fine powder passing through a 1,000 mesh sieve.

The foaming agent serves to foam the foaming paste polyvinyl chloride (PVC) resin, the mixing amount is preferably 0.5 to 1.0% by weight. When the mixing amount of the blowing agent is less than 0.5% by weight, the foaming paste polyvinyl chloride (PVC) resin may not be sufficiently foamed, and thus the elastic force may be lowered. When it exceeds 1.0% by weight, the foaming paste polyvinyl chloride is used. (PVC) The resin may be over-foamed and the surface of the thermoplastic resin sheet may be too soft, which may interfere with the printing operation. In addition, the foam usable in the present invention is preferably used by selecting one of azodicarbonamide and benzene sulfonyl hydrazide.

The stabilizer serves to prevent the change of color, which is a thermal decomposition phenomenon of the polyvinyl chloride (PVC) resin and the foaming paste polyvinyl chloride (PVC) resin, and thus the deterioration of properties of the finished product and the generation of hydrogen chloride gas. Silver is preferably 0.5 to 1.0% by weight. When the amount of the stabilizer is less than 0.5% by weight, the resins may be discolored or the properties thereof are deteriorated due to the lack of the stabilizer content. There exists a possibility that the thermoplastic resin sheet of the physical property may not be manufactured. The stabilizer usable in the present invention preferably uses a Ba-Zn liquid stabilizer.

And the thermoplastic resin sheet of the present invention is manufactured by molding at a temperature of 170 ~ 210 ℃ by molding in a mold after mixing the above components.
