Problems solved by technology

[0006] Also, many efforts have been made to apply the existing silver nanoparticles, but there are problems in the separation of silver nanoparticles, in terms of being contained in the plastic itself rather than the surface coating method, and there are not only inability to provide uniform quality, And the problem of decreased antibacterial ability

Embodiment 1

[0098] Preparation of amphibole slurry

[0099] After the raw amphibole crushed into 0.1-5mm is put into the furnace, the temperature and pressure are adjusted so that the temperature reaches 1200°C.

[0100] In the first ignition, the pressure was adjusted to 0.1 kg / hour using liquefied petroleum gas (LPG) (hereinafter referred to as "gas") in the furnace, and the temperature was brought to 300°C within 1 hour.

[0101] After 1 hour, the gas pressure was adjusted to 0.125 kg / hr to bring the temperature to 500°C within 1 hour.

[0102] When 500°C was reached, the gas pressure was adjusted to 0.15 kg / hour to bring the temperature to 700°C within 1 hour.

[0103] When the temperature in the furnace reached 700°C, the gas pressure was adjusted to 0.2 kg / hour to bring the temperature to 850°C within 1 hour.

[0104] When the temperature reaches 850°C, the gas pressure is fixed at 0.2 kg / hour and maintained for about 1 hour for complete combustion of the organic substances contai...

Embodiment 2

[0113] Preparation of amphibole granules

[0114] In order to increase the porosity of the final particles, a 1:1 weight ratio mixture of calcium carbonate and sodium carbonate was added to the slurry prepared in Example 1 as a foaming agent, relative to 100 parts by weight of the solid content of the slurry. , adding 5 parts by weight, adding 1 part by weight of silver nanoparticles as antibacterial substances to prepare a granulated mixture.

[0115] Then, for granulation, the furnace of the hot blast furnace is ignited by spray drying method and the temperature is raised within 2 hours to make the internal temperature reach 1000°C. 300 ℃, put the nozzle into the lower end of the cyclone, and the temperature is 40kgf / cm 2 The pump pressure scatters the finely divided granulated mixture at the upper point of the inflow weight.

[0116] The radiated liquid phase falls off due to eddy currents caused by the hot air flowing in from the upper side of the cyclone, thereby formin...

Embodiment 3

[0120] Preparation of masterbatch

[0121] Low-density polyethylene was prepared as a plastic raw material, and the above-mentioned amphibole particles were made into 30% by weight, mixed with 70% by weight of low-density polyethylene, and then put into a melt extruder.

[0122] The temperature inside the furnace of the melt extruder is set at 180-350°C. While realizing the melting of the plastic raw material, the amphibole particles are uniformly dispersed in the plastic raw material and extruded. After cooling the extruded material, it is prepared by cutting. masterbatch.

[0123] Image 6 The left side shows the low-density polyethylene plastic raw material, the middle shows the amphibole particles, and the right side shows the masterbatch.

Abstract

The present invention relates to a method for preparing a masterbatch for preparing plastic products, and to a method for preparing an antimicrobial plastic masterbatch of amphibole particles, that is, when the particles are melted, an antibacterial substance is contained, and by adding the amphibole as a raw material The porous calcined particles enable it to exert high far-infrared radiation and excellent antibacterial effect.

Description

technical field [0001] The present invention relates to a method for preparing a master batch used for preparing plastic products, and relates to a method for preparing an antibacterial plastic master batch of fenugreek granules as follows, that is, when the particles are melted, an antibacterial substance is contained, and the fenugreek is used as a raw material by adding Porous calcined particles to enable it to exert high far-infrared radiation and excellent antibacterial effect. Background technique [0002] It is known that antibacterial plastics contain antibacterial substances in plastics, so as to have sterilization and antibacterial effects, and have antifungal ability, anticorrosion, preservation, deodorization and other functions. [0003] As a technology related to the preparation of antibacterial plastics, "Antibacterial plastic materials, antibacterial plastics, master batches for the preparation of antibacterial plastics, and methods for preparing antibacteria...
