Abstract
本发明涉及一种高温无机抗菌剂，属新材料领域。该抗菌剂由抗菌金属离子、主载体和附属载体组成。其中提供抗菌金属离子的材料为AgNO3、CuO、ZnO，主载体为CaSO4、Al6Si2O13、ZrO2，附属载体为SiO2、Al2O3。抗菌剂用固态反应烧结制成。该高温无机抗菌剂具有成本低廉、抗菌率高、耐高温性好等优点。可广泛用于建筑材料、日用陶瓷、塑料、涂料、油漆、纸、纺织品及木材等中。The invention relates to a high-temperature inorganic antibacterial agent, which belongs to the field of new materials. The antibacterial agent is composed of antibacterial metal ions, main carrier and auxiliary carrier. Among them, the materials providing antibacterial metal ions are AgNO 3 , CuO, ZnO, the main carriers are CaSO 4 , Al 6 Si 2 O 13 , ZrO 2 , and the auxiliary carriers are SiO 2 , Al 2 O 3 . The antimicrobial is made by solid state reaction sintering. The high temperature inorganic antibacterial agent has the advantages of low cost, high antibacterial rate, good high temperature resistance and the like. It can be widely used in building materials, household ceramics, plastics, coatings, paints, paper, textiles and wood, etc.
Description
The present invention relates to a kind of high-temp inorganic antibacterial agent, belong to field of new.
Existing inorganic antiseptic combines by high efficiency and the broad spectrum activity with inorganic material inherent stability and antibiotic composition, has successfully overcome safety in utilization, persistence, the broad-spectrum antibacterial property of organic anti-bacterial material, the shortcoming of warm tolerance equal difference.But still exist when temperature during above 1200 ℃ of left and right sides, its antibacterial effect extreme difference that just becomes almost loses the shortcoming of antibacterial effect.
The objective of the invention is to overcome the deficiency of prior art, and provide a kind of with low cost, antibiotic rate is high, heat-resisting quantity good, the high-temp inorganic antibacterial agent that the scope of application is wide.
The present invention is achieved in that this high-temp inorganic antibacterial agent is made up of antibacterial metal ions and carrier.Wherein, antibacterial metal ions is by AgNO
3, among CuO, the ZnO any one, two kinds or three kinds select acquisition simultaneously for use, its monodrome or and value shared percentage by weight in always filling a prescription be not less than 4%.Span is respectively: AgNO
3Get that 0～10wt%, CuO get 0～10wt%, ZnO gets 0～20wt%.Carrier is made up of main carrier and attached carrier, and main carrier is CaSO

3In any one or two kinds select for use simultaneously, its monodrome or and value shared percentage by weight can not be less than 1% in total prescription, its span is 0～15wt%.Antibacterial agent is made with solid state reaction sintering.
Embodiments of the invention are as follows:
Select for use down the each component in the page table to determine prescription, technology weighing routinely, mixings of preparing, mill, afterwards again through solid state reaction sintering (temperature is got 750 ℃～1300 ℃, and the time is more than one hour) are milled carefully, operation such as packing and obtain high-temp inorganic antibacterial agent.This high-temp inorganic antibacterial agent after testing, its antibiotic circle is more than 1mm, the minimum growth stops concentration MIC all less than 300ppm.This antibacterial agent mixes the domestic ceramics glaze and imposes on billet surface, and its antibiotic rate reaches 99.99%.Antibacterial agent is made with solid state reaction sintering.
The present invention compared with prior art has advantages such as with low cost, that antibiotic rate is high, heat-resisting quantity is good.Can be widely used in construction material, domestic ceramics, plastics, coating, paint, paper, textile and the timber etc.
