preparation example 1

[0076] Preparation of silica sol loaded with nano silver-titanium dioxide

[0077] 1) Weigh 17.0 mg of silver nitrate, add 100 ml of deionized water to dissolve and prepare a 1 mmol / L silver nitrate solution, and store the prepared silver nitrate solution in a brown volumetric flask away from light. Take 60ml of the above-mentioned silver nitrate solution and place it in a conical reaction flask with a stirring bar, add 9ml of 40mM sodium citrate solution as a stabilizer, stir for 5min, then add dropwise 6ml of 10mM sodium borohydride under rapid stirring and dark conditions The solution was stirred while adding dropwise, and magnetic stirring was continued for 3 h after the dropwise addition was completed to obtain a clear nano-silver solution.

[0078] 2) Take 50mL of the above nano-silver solution, slowly drop it into 600g of 10% silica sol solution (silicon dioxide dispersion solution), avoid light, and ultrasonically disperse evenly.

[0079] 3) Weigh 1.2 g of nano-titan...

[0085] Preparation of Polyvinyl Alcohol Dispersion of Antibacterial Composite Microspheres

[0086] At 60°C, the antibacterial composite microspheres obtained in Preparation Example 2 were added to a certain amount of 3wt% mass fraction of polyvinyl alcohol transparent solution, magnetically stirred for 60min, then ultrasonically oscillated for dispersal for 15min, and then magnetically stirred for 60min again after ultrasonically oscillated. Obtain the antimicrobial microparticle dispersion, wherein the mass percent of the antibacterial microsphere in the antibacterial composite microsphere dispersion is 12%.

Abstract

The invention relates to a bacteriostatic isolation coating film-forming liquid for a medical inspection platform and a preparation method thereof. The film-forming liquid containing solid micro-particles comprises a silica sol component loaded with nano silver-titanium dioxide, a nano silver-doped organic-modified mesoporous silica antibacterial composite microsphere component, a composite organic resin component, polyhexamethylene biguanide hydrochloride or phosphate, and an other auxiliary agent component. The bacteriostatic isolation coating film-forming liquid can be used for the surfacefilm-forming isolation use of the hospital inspection platform such as various working or operating tables, appliance storage-taking brackets or working cabinets, and has excellent disinfection bacteriostatic function and hydrophobic and easy-cleaning function.

Description

technical field [0001] The invention belongs to the field of medical composite materials, and in particular relates to an emulsion-type coating film-forming liquid composition of nano silver-containing antibacterial particle deposition composite resin and a preparation method thereof. Background technique [0002] Medical testing is a bridge between clinical and basic medicine, including clinical chemistry, microbial culture, immunology, hematology and body fluid blood and other disciplines, involving biochemical testing, immune testing and microbial testing. Medical examination plays a very important role in clinical diagnosis, judgment of curative effect and prognosis. [0003] In hospitals, medical tests usually carry out culture and testing of materials taken from the human body in the fields of microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology, etc., involving disposable testing equipment, patients The detection of body fluids and tissu...
