Description
The present invention relates to a PVC resin composition for manufacturing a water and sewage pipe having high tensile strength, impact resistance, antibacterial and deodorizing function, and a water supply and drainage pipe using the PVC resin composition. The present invention can reduce the odor of disinfectant flowing in tap water, The present invention relates to a PVC resin composition for manufacturing a water and sewage pipe having an antibacterial function for reducing the odor generated in a sewer pipe, a connection pipe, a water bath, and the like and preventing the propagation of various bacteria.
Up to now, water and sewage pipes are heat stabilizers and impact modifiers in PVC resin. PVC tubing which is extruded with a mixture of antioxidants and lubricants. Antimicrobial water and sewage pipes containing organic and inorganic antimicrobial agents are being produced and sold. Particularly, currently used inorganic antibacterial agents are metal ions such as silver, copper and zinc However, these metals have problems such as toxicity and discoloration due to oxidation, and they are avoided to use. In order to prevent such side effects as described above, various kinds of inorganic antimicrobial agents for water supply and drainage pipes have been developed.
As a related prior art, Korean Patent No. 10-877201 discloses an antimicrobial agent for enhancing the antimicrobial activity of outer layer (1) and inner layer (3), such as zinc 2-pyridenthol-1-oxide and zirconium phosphate, , A silica-based antimicrobial agent (product name: Silvix Nanosilver Composite Powder) composed of SiO2 98.25%, water 0.25% and Al2O3 1.00%.
In Korean Patent No. 10-384929, 25 weight% of ferrous sulfate aqueous solution and 25 weight% of EDTA are added to prevent skim formation in the water supply and drainage pipe caused by fungi and various noxious bacteria propagation, 10 to 40% by weight of an aqueous solution of ferrous sulfate stabilized with 50% by weight of a calcium carbonate compound and 10 to 40% by weight of EDTA are added in a neutral aqueous solution.
In addition, Korean Patent No. 10-1260031 discloses a technique for obtaining an antibacterial effect by mixing 1 to 3 parts by weight of a fragrant wood powder having an average particle diameter of 20 mu m, and in Korean Patent No. 10-969655, a zeolite has an antibacterial effect And vermiculite has a far infrared ray emission effect and antimicrobial property and acts as a filler while the phosphate compound is a component having antimicrobial activity and is composed of a primary phosphate, a secondary phosphate, a hexametaphosphate and a tetra Discloses a technique for increasing the antibacterial property by combining at least one selected from potassium phosphate (Mono-Phosphate, Di-Phosphate, Hexameta-Phosphate and Tetra-Potassium Pyrophosphate).
Korean Patent No. 10-890796 discloses a technique for an antibacterial zeolite containing 0.1 to 3 mass%, which is not limited to an additive for an antimicrobial agent in a water pipe, but has antimicrobial activity against fungi and the like.
However, the above-mentioned prior arts have antibacterial ability to inhibit the propagation of germs, and there is a limit to the original removal of the odor of the disinfectant generated from tap water, and the level of antibacterial performance and odor removal are not satisfactory.
The object of the present invention is to develop an antibacterial material having excellent dispersibility and lasting antibacterial effect semi-permanently.
It is another object of the present invention to develop a material having a deodorizing and deodorizing function.
It is another object of the present invention to provide a water supply and drainage pipe and a joint pipe having high antibacterial power and excellent deodorizing and deodorizing function as well as mechanical strength.
Existing water and sewage pipes are heat stabilizers and impact modifiers in PVC resin. And some of them are produced and sold. In particular, metal ions such as silver, copper, and zinc are mainly used as inorganic antibacterial agents currently being used. In the case of copper, it is applied only to the construction materials due to the problem of toxicity and discoloration due to oxidation, and silver is the most applied in practice. In the case of silver ions, it binds to the cell wall to interfere with energy transfer. When it penetrates into the cell, it binds with the sulfur component of the protein, thereby inhibiting the enzyme that causes metabolism, thereby blocking the propagation of bacteria. Specifically, The metal particles are ionized from the impregnated metal components and eluted to the plastic surface. The silver particles are eluted at a concentration of several ppb. The dissolution of metal ions by contact with the water present in the air on the surface of the plastic is shown in the following [ Picture].
[Drawing]
In addition, inorganic antibacterial agents have advantages such as excellent durability due to a slow dissolution rate, little environmental or human hazard due to very small amount of elution, and excellent thermal stability. On the other hand, the inorganic antibacterial agent has advantages such as dispersibility, discolouration, , And relatively high prices. Recently, the development of nanotechnology has led to the development of nanoparticles rather than bulk particles. In the case of using nanoparticles, it is possible to maximize the elution by increasing the specific surface area with respect to the mass. So that the price can be dramatically lowered. Actually, when it is added to plastic, it should be more than 2500ppm to exhibit antibacterial and germicidal effect by elution, but since nanoparticles are used, the same effect is exhibited even at a concentration of 100ppm. However, it has been difficult to process nanoparticles with polymers until now, and the effective concentration of nanoparticles to exhibit antibacterial and germicidal effects varies depending on the degree of technological development. Particularly, it is urgent to research and develop dispersion of nanoparticles in polymer resin to be. Inorganic antibacterial agents are antimicrobial agents in which inorganic carriers are substituted with silver, copper and zinc, and when they are mixed with powdered PVC resin, their dispersibility is low and they can not exert their antimicrobial activity. In order to solve the problem of dispersibility, the present invention adds a wax-based dispersant (DP720) to disperse the dispersibility smoothly and uniformly to maximize the antibacterial activity.
