Description

Functional synthetic plastics and its manufacturing method

The present invention relates to a functional synthetic plastics and a method for manufacturing the same, and more particularly, to a synthetic resin plastic and a method for producing the same, which provides excellent antibacterial and antifungal effects as well as far-infrared radiation by using Korea.

In general, synthetic resin is a material derived from petroleum, and its variety is diverse, and its use is almost infinitely unused in real life products, and has an infinite range of applications in various fields. However, since synthetic resins are convenient and inexpensive to manufacture, they are limited in their use in the fields of direct contact with the human body because they are harmful to the human body such as environmental hormones, as well as wastewater problems and harmful substances generated during manufacturing.

Thus, many attempts have been made to add various functional additives to impart functionality to synthetic resins. Recently, research is being actively conducted to add jade, mica, hornblende, elvan, loess, and charcoal, which are known to be beneficial to health, to synthetic resins.

Korean Laid-Open Patent Publication No. 94-21638 discloses a method for preparing a master batch beneficial to the human body by mixing polyester resin and jade powder, and Korean Laid-Open Patent Publication No. 2002-0070672 describes a technique of adding a mineral (mica). However, its functionality cannot be satisfied.

Korean Patent Publication No. 10-354848 discloses a technique for adding a mineral and a silver antibacterial agent. However, they cannot effectively impart antimicrobial properties to resins, and have insufficient radiation of far infrared rays. Korean Patent Publication No. 10-429151 discloses a method of adding jade to an acrylic resin, but the jade powder is uniformly applied to the acrylic resin. There was a problem that was not mixed.

Korean Patent Publication No. 10-0558893 describes adding germanium powder to synthetic resins, but it is not enough to have antimicrobial properties, and due to strength problems during manufacturing, only a small amount of germanium powder is added to reduce the amount of synthetic resins. There was this. In addition, Korean Patent Publication No. 10-2010-0000379 discloses an eco-friendly functional synthetic resin composition using volcanic stones, but since the particles of the powder are not uniform, the dispersion is not uniform, and thus there is a limit in showing its functionality.

In addition, there are many patents for adding various mineral additives to impart functionality to synthetic resins, but there have been no satisfactory results.

Therefore, the additives are pulverized to ultra fine granules to spread and distribute uniformly to increase the amount of additives, and to have far-infrared radiation activity, antibacterial and antifungal effects, and to produce environmental pollution such as environmental hormones, wastewater and harmful substances that are harmful to the human body. We can reduce the environmental pollution of the earth by reducing the use of.

The present invention was developed to solve and solve the following problems, and the far-infrared emissivity is excellent by diffusing, distributing and uniformly mixing the natural S Korea powder pulverized with an ultra fine particle size (1.0-70 ㎛) in a synthetic resin. In addition, the antimicrobial and antifungal properties are very excellent, and unlike conventional methods, the purpose is to provide a functional synthetic resin that can reduce the amount of synthetic resin by increasing the use ratio in the synthetic resin.

In the manufacturing method of eco-friendly functional synthetic resin plastic composition using a sKorea 1 step of coarsely crushing 3-4 ㎝ SKOREA gemstone into 300-400 mesh; Wet grinding with a bead mill to widen the pores; Three steps of drying the powder again; Pulverizing the dried powder stably at an ultrafine particle size (1.0-70 μm) with an air jet mill by a high speed jet stream to obtain a powder that could not be obtained by the conventional method; And 0.05-25.0 wt% of SKOKO powder and 0.001-1.0 wt% of siliculum-based admixture per 100 wt% of resin, wherein the ultra fine powder is extruded by dispersing, distributing and uniformly mixing it with synthetic resin. Characterized in that it comprises a step.

The functional synthetic resin of the present invention is very excellent in far-infrared emissivity, antimicrobial and anti-mildew, and diffuses, distributes and uniforms natural crushed powder with high fineness (1.0-70㎛) at a higher ratio than conventional functional additives. By using a mixture of synthetic resins, the amount of synthetic resin can be reduced, so that it can be widely used without limitation for various products frequently contacting the human body, and there are various beneficial effects that can reduce environmental pollution.

       SKOREA is an ideal black sand body that emits more than 92% of negative ions and more than 94% of far infrared rays when heated to 200 ℃ at room temperature (below 40 ℃), and especially titanium dioxide which is not found in ocher, jade, albite and germanium. As it exists in the state of 3-7% and acts as a photocatalyst, SKOREA receives light energy and electrons continue to move, and holes are generated from all over the place. This is a mysterious natural material.

Synthetic resins used in the present invention can be recycled and used as well as all synthetic resins that are generally used, polyethylene, polypropylene, polystyrene, synthetic rubber, vinyl chloride resin, vinylidene chloride resin, vinyl acetate resin, poly Vinyl alcohol, polyvinyl acetal, polymethyl methacrylate, polyacrylate, nylon (polyamide), polyethylene terephthalate, polyester, polycarbonate, polyether, polyfluoroethylene, phenol resin, urea resin, melanin resin, Unsaturated polyester resin, epoxy resin, alkyd resin, silicon resin, polyurethane resin, ion exchange resin, polysulfone, PPO and Noryl resin, ionomer, polyimide, polyamideimide, polybenzimidazole, PPS resin, ABS resin, One or more of those consisting of polybutylene terephthalate are used alone or in combination Can.

Sukko powder and synthetic resin of the present invention are mixed uniformly for 5-15 minutes using a mixer. In addition, additives such as antioxidants, corrosion inhibitors, stabilizers, and glazes may be used depending on the type of synthetic resin. The additive may use those known in the art.

The raw materials mixed as follows may be extruded using an extruder generally used in the art, and then cooled by water or air cooling, and then cooled and cut into 1-10 mm pellets for sale. have.

Thus prepared synthetic resin of the present invention can be effectively used in all products that are expected to come into contact with the human body because it is very excellent in far-infrared emissivity, antibacterial and anti-fungal properties.

Hereinafter, the present invention will be described in detail with reference to examples.

Coarse crushed 3-4 cm gemstones in 300-400 mesh to provide fine powder. The powder is then wet milled with a bead mill to widen the pores, and the powder is dried again. 0.05-25.0 weight% of fine powder and 0.001-1.0 weight% of siliceous-based admixture, which could not be obtained by the conventional method by stably pulverizing the dried powder to ultra-fine particle size of 1.0-70 μm by air jet mill by high speed jet stream It characterized in that it comprises an ultra-fine particle size powder in a synthetic resin diffusion, distribution and uniformly mixed by extrusion molding, cooling and cutting to prepare a pellet for injection of 1-10㎜. Far-infrared emission, antibacterial and antifungal tests were performed on the pellets by KICM. The far-infrared radiation was tested according to KICM-FIR-1005. Mold testing was performed according to ASTM G-21. The results are shown in Tables 1-3 and Figures 1-4, respectively.
