Abstract
The invention discloses a silver antibiosis powder and an antibiosis ceramic and an antibiosis plastic with bacteria-proof walls. The silver antibiosis powder is prepared by reaction of hydroxyapatite with particle size of 100-200nm with silver nitrate with particle size of 100-200nm. The antibiosis ceramic with the bacteria-proof wall is prepared by adding 0.4-0.5 percent of the silver antibiosis powder in percentage by weight into ceramic glaze. The antibiosis plastic with the bacteria-proof wall is prepared by adding 0.5-0.6 percent of the silver antibiosis powder in percentage by weight into parent particles. The prepared nanometer silver antibiosis powder can achieve 100 percent of antibiosis effect to escherichia coli and staphylococcus aureus on the surfaces of the antibiosis ceramic and the antibiosis plastic when the using amount is 0.5 percent (in percentage by weight).
Description
Technical field
The present invention relates to inorganic antiseptic, specifically a kind of silver-colored antimicrobial powder and band are every the anti-bacteria ceramic and the antibiotic plastic of bacterium wall.
Background technology
At present, when using inorganic antiseptic to produce goods such as anti-bacteria ceramic and antibiotic plastic, the addition of inorganic antiseptic directly influences the appearance luster of anti-microbial property and goods, anti-microbial property raises along with increasing of antibacterial agent addition, but the appearance luster of goods can increasing and blackening along with the antibacterial agent addition.Therefore, existing inorganic antiseptic can't be produced pottery, the plastic products that make the best of both worlds.
Summary of the invention
Purpose of the present invention just provides a kind of silver-colored antimicrobial powder, and this powder just can make the anti-microbial property of made pottery, plastic products satisfy instructions for use under the less situation of consumption, thereby does not influence the appearance luster of goods.
Another purpose of the present invention just provides the anti-bacteria ceramic of a kind of band every the bacterium wall, so that made ceramic has antibiotic resistance performance, uses needs thereby satisfy the user.
Further aim of the present invention just provides the antibiotic plastic of a kind of band every the bacterium wall, so that made plastic articles has antibiotic resistance performance, uses needs thereby satisfy the user.
The present invention is achieved in that silver-colored antimicrobial powder of the present invention is to be made in the silver nitrate reaction of 100-200nm at hydroxyapatite and the particle diameter of 100-200nm by particle diameter.
Band of the present invention is to be that the silver-colored antimicrobial powder of 0.4-0.5% makes add percentage by weight in ceramic glaze every the anti-bacteria ceramic of bacterium wall.
Band of the present invention is that to add percentage by weight in master batch be that the silver-colored antimicrobial powder of 0.5-0.6% makes every the antibiotic plastic of bacterium wall.
The nanometer-level silver antimicrobial powder that the present invention makes just can make anti-bacteria ceramic and antibiotic plastic surface reach when consumption is 0.5% (percentage by weight) Escherichia coli and staphylococcus aureus antibiotic rate are reached 100% antibacterial effect.
