Abstract
The new process of preparing nano antibacterial material features the comprehensive interlayer insertion process of organic/inorganic composite antibacterial material. The present invention prepares nano antibacterial material by using silicate mineral and zirconium phosphate as carrier and through superfine processing, combined wet and dry milling, graidng, absorption of contact antibacterial component and photocatalyst, drying high-energy surface treatment, dispersing and high temperature calcinations.
Description
The present invention relates to the technology of preparing of nano anti-biotic material, be specifically related to insertion technology (intercalation) between inorganic/organic composite antibiotic synthetic layer, technology of preparing, preparation technology and method, its feature comprises the new technology that adopts the active reactive group utilize chemicals directly to introduce antibacterial agent on macromolecular chain.
The environmental protection protection has been subjected to the people's of the world today great attention, and anti-biotic material is the important component part of environment-friendly materials.Air and water pollution needs to purify; The sealing of dwelling house is very high now, poor aeration, and indoor temperature is higher relatively, and such environment provides good condition for the breeding growth of mould, and people need use antibacterial product, reach the purpose of cleaning ambient.
It all is that the colour stable aspect of single inorganic antiseptic has obtained significant achievement that the corporate boss that domestic present antibacterial agent is developed wants direction.And a collection of new material, High-tech company have occurred and be engaged in the exploitation of anti-biotic material and apply.Develop insertion technology (intercalation) between inorganic/organic composite antibiotic synthetic layer, technology of preparing, preparation technology and method, its feature comprises the new technology that adopts the active reactive group utilize chemicals directly to introduce antibacterial agent on macromolecular chain.Study seldom, especially the antibacterial agent of using in the macromolecular material of high-performance, multifunction just begins.
The object of the present invention is to provide that a kind of equipment is simple, the new preparation process of technological process weak point, small investment, production nano anti-biotic material that cost is low.
The technical characterstic of this invention: with inorganic nano material is that carrier carried (silver, copper, zinc etc.) some metals are ion, the inorganic nanometer functional material that utilizes physics and chemical method to combine to produce is called for short (antibacterial agent), and main carrier is silicate mineral, titanium dioxide, basic zirconium phosphate.Aspect anti-biotic material processing, utilize on the macromolecular chain of active reactive group of compound and directly introduce antibacterial agent.Say an organic compound antibacterial agent introducing metal ion (Ag clearly
+Deng) in the lamellar spacing of the inorganic carrier that exchanged, improve its heatproof degree; Through in the ultra-fine grinding process, temperature reaches 120 ℃ of silver ions and organic antibacterial agent can discharge at leisure together, reaches potent antibiotic purpose.
The present invention will further specify by following examples.
The basic zirconium phosphate of getting 1 kilogram of silicate mineral and 0.17 kilogram adopts nanometer super-fine processing technology through doing wet combination, the ball milling comminution by gas stream, complex methods such as ultra-fine agitator, other the antibiotic composition of contact in multistage mother liquor separation classification process receives with photocatalysis and receives, after through energetic surface treatment in 15 minutes, use the HT-115 beater to break up in the process of the anti-biotic material drying after the classification, in the process of breaing up, add additive A+B again, the organic compound antibacterial agent is introduced metal ion (Ag
+Deng) in the lamellar spacing of the inorganic carrier that exchanged, improve its heatproof degree; Through in the ultra-fine grinding process, temperature reaches 120 ℃ of silver ions and organic antibacterial agent can discharge at leisure together, accomplishes long-acting 5 years and high-efficient antibacterial agent.The antibacterial agent of different purposes can surface modification treatment according to user's needs.
Claims (2)
1. the new preparation process of a nano anti-biotic material is characterized in that adopting and inserts legal system between inorganic/organic composite antibiotic synthetic layer and be equipped with technology.
According to claims 1 described inorganic/the organic composite antibiotic synthetic layer between insertion, mainly be that the organic compound antibacterial agent is introduced metal ion (Ag
+) etc.In the lamellar spacing by the inorganic carrier (silicate mineral, basic zirconium phosphate) that exchanged, the temperature that improves its heatproof degree, ultra-fine ore deposit reaches 120 ℃.
