Abstract

PURPOSE: A manufacturing method of an antibacterial roller for windows and doors is provided to manufacture the antibacterial roller for windows and doors that can be used very hygienically by adding an antibacterial agent of about 0.7 to 0.8 wt.% to a synthetic resin raw material for manufacturing the roller. CONSTITUTION: The manufacturing method of an antibacterial roller for windows and doors comprises the process of injection molding the mixture at a temperature of 170 to 180 deg.C after mixing an antibacterial agent such as zeolite comprising silver, zinc and copper, calcium phosphate, silver compounds such as silver iodide and silver chloride, or Bio Hunter RX-301 produced by Clean Zone Corporation with an ordinary synthetic resin for manufacturing a roller for windows and doors in an amount of 0.7 to 0.9 wt.%, wherein the manufactured antibacterial roller for windows and doors is capable of preventing parasitism and propagation of various harmful bacteria such as Staphylococcus aureus ATCC 6538, Lscherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 4352, Salmonella typhimunum KCTC 1925, and Aspergillus niger ATCC 10254.

Description

A manufacturing method of an antibacterial roller for windows and doors}

The present invention relates to a method for producing an antibacterial roller for windows and doors.

As is well known, rollers for window and door are usually injection molded as synthetic resin, but are used by insert molding bearings in the center, and when using them, they are fixedly mounted on the window frame or the bottom of the window frame while being assembled to the roller frame. It is also used to open and close the door very smoothly.

However, in general, windows and windows should be formed such as a windscreen jaw, etc. in order to easily open and close the window by slide type, and the space between them is narrow as the rails and the windscreen are formed three-dimensionally, so that there are various dusts or foreign substances here. This is easily caught, of course, staphylococcus, E. coli, pneumoniae, Salmonella, fungi, etc. will be inhabited, which is very unsanitary.

In addition. The above-mentioned germs cause various diseases in going out for human life and at the same time act as a disaster that destroys the clean environment.

Therefore, the present invention was invented to prevent the parasitic and breeding or occurrence of various bacteria in windows and door frames, and in particular, the general synthetic resin raw materials for manufacturing rollers include zeolite containing silver, zinc, copper, or the like. 0.7-0.9 wt% of an antimicrobial agent, such as calcium phosphate, silver iodide, silver chloride, or silver chloride, is mixed and injection molded at 170-180 ° C., so that E. coli, pneumococci, Salmonella, and fungi, including Staphylococcus, are used during installation. It is an object of the present invention to provide a method for producing an antibacterial roller that can prevent the parasitic and propagation of various harmful bacteria such as bacteria.

In addition, when the antimicrobial agent is added to various windows and doors made of synthetic resin, the sanitary windows and doors can be manufactured and supplied even more hygienic.

<Example 1>

Injection molding is carried out at 170-180 ° C. by mixing 0.7-0.9 wt% of a conventional synthetic resin for producing window rollers with an antimicrobial agent such as zeolite including silver, zinc, copper, or calcium phosphate.

<Example 2>

0.7-0.9 wt% of silver compounds, such as silver iodide and silver chloride, are mixed in the conventional synthetic resin for manufacturing the roller for windows and windows, and injection molding is carried out at 170-180 ° C.

<Example 3>

Bio Hunter RX-301, a manufactured product of 'Cleanzone', is mixed with ordinary synthetic resin for manufacturing rollers for windows and windows, and injection molding is performed at 170 ° C -180 ° C.

Since the antibacterial roller manufactured by the above method has excellent antibacterial effect, it is very effective in preventing the sterilization and propagation of various bacteria such as Salmonella and Staphylococcus aureus.

The following is a test result for the antimicrobial roller manufactured by the manufacturing method of the present invention at the Korea Chemical Research Institute.

Antimicrobial activity measurement method; KS K 0693 (Bacterial Counting Method)

Test result;

Staphylococcus (Sfaphlococcus aureus ATCC 6538)

Initial strain number before test: 7.0 × 10 ⁴ '

Viable cell count after test '0'

100% bacteria reduction rate

Escherichia coli (Lscherichia coli ATCC 25922)

Initial strain before test '2.0 × 10'

Viable cell count after test '1.0 × 10 ⁴ '

Reduction rate of germs '99.9%'

Pneumococcal (Klebsiella pneumoniae ATCC 4352)

Initial bacterial count before test '1.4 × 10'

Test water viable count '0'

Bacterial reduction rate '100%'

Salmonella typhimunum KCTC 1925

Initial strain before test '1,2 × 10'

Viable cell count after test '1.0 × 10 ³ '

Bacterial reduction rate '99.9%'

Fungus (Aspergillus niger ATCC 10254)

Initial strain before test '2.8 × 10'

Viable cell count after test '1.0 × 10 ³ '

Bacterial reduction rate '99.9%'

As can be seen from the above test results, the present invention, in the manufacture of antimicrobial rollers for windows and doors with synthetic resin, by adding and mixing antimicrobial agents, makes it possible to prevent staphylococcus aureus and various bacteria propagation and very hygienic use.

In addition, in the manufacture of various windows and doors made of synthetic resin in addition to the roller for windows and doors can be used more hygienically if the antimicrobial agent is added.

As described above, in the injection molding of a window and door roller, 0.7 to 0.9 wt% of a zeolite containing silver, zinc, copper, or the like and a silver compound such as calcium phosphate, silver iodide, silver chloride, etc. are mixed, By injection molding at 170˚C-180˚C, it is a very useful invention that can be used very hygienic and stable due to its excellent antibacterial activity.
