Abstract
The invention discloses a method for preparing an antibacterial acrylic plate from stellerite. According to the invention, stellerite is adopted as a raw material, and is elutriated and crushed; sodium-type zeolite, cupric nitrate, zinc nitrate, and silver nitrate are sequentially added to sodium-type zeolite according to a certain ratio, and the mixture is stirred; the mixture is stood for 2 hours, and is washed, until the mixture is neutralized; the mixture is dried by baking, such that a stellerite antibacterial agent is obtained; the prepared stellerite antibacterial agent is added to an acrylic plate substrate, and the mixture is well mixed and foamed, such that a stellerite antibacterial acrylic plate is prepared. With the method, the prepared antibacterial acrylic plate has functions of bacterium resistance, mildew resistance, far-infrared effects, and the like. The antibacterial effect is above 95%. Compared with common products, the acrylic plate with the added stellerite antibacterial agent is advantaged in higher smoothness, higher brilliance, high efficiency, and heat resistance. After long-time use, the good antibacterial performance of the acrylic plate is maintained.
Description

2O.Natural parastilbite is that natural zeolite is the aluminium silicate mineral of a kind of aqueous basic metal or earth alkali metal, the tectosilicate of being made up of silicon-oxy tetrahedron and aluminum-oxygen tetrahedron.To have the monovalence end to obtain saturated for Sauerstoffatom in its aluminum-oxygen tetrahedron, and whole aluminum-oxygen tetrahedron has negative charge, comes compensation balance with near the positively charged ion of positively charged.Open structure helps IX, because the influence of hydrate free energy is bigger.Function with molecular sieve is like absorption and ion exchange.
With the preparation of antimicrobial acrylic board of stellerite copper loaded, zinc, three kinds of antibacterial metal ions of silver, Shang Weijian has report.
Summary of the invention
The objective of the invention is to disclose a kind of method for preparing antibiotic acrylic board with stellerite.
The present invention prepares the method for antibiotic acrylic board with stellerite, comprises the steps:
(1) is raw material with the natural parastilbite ore deposit, raw ore eluriated that grinding and processing is to the 550-600 order;
(2) be that ratio is added in the na-pretreated zeolite successively with 1g na-pretreated zeolite, 0.1M cupric nitrate 5ml, 0.1M zinc nitrate 5ml, 0.1M Silver Nitrate 10ml; After under the insulation stirring reaction 2-3 hour; Room temperature held 2 hours; Washing gets the antiseptic-germicide of copper, zinc, silver-colored mixed load to neutral after the oven dry;
(3) antiseptic-germicide with stellerite mixed load copper, zinc, silver-colored antibacterial metal ions adds in the acrylic board base material;
(4) with prior art the acrylic board base material is processed pressing plate, make antibiotic acrylic board.
The mass ratio of the interpolation of described stellerite antiseptic-germicide is: acrylic plate substrate ︰ stellerite antiseptic-germicide=100 ︰ 5;
The natural parastilbite that described stellerite produces for the Guangxi resource, its purity is high, and iron level is low to moderate 0.27, and whiteness is near 90%, and crystal is big.
The antibacterial experiment of the antibiotic acrylic board of stellerite of the present invention shows, colibacillary antibiotic rate is reached 96.8%, and the antibiotic rate of streptococcus aureus is reached 95.2%.
Advantage of the present invention is: the antibiotic acrylic board of preparation has functions such as antibiotic, mildew-resistant, far infrared effect, and antibacterial effect reaches more than 95%, can kill bacterium, the mould on contact product surface, prevents that dirt and bacterial plaque from appearring in the surface; Stellerite antiseptic-germicide dispersing property is good, and available ordinary method is distributed in the base material, and is safe, non-stimulated; The acrylic board that adds the stellerite antiseptic-germicide is Paint Gloss bright with respect to common product, and efficient is high, and is heat-resisting, still keeps the excellent antibiotic performance through long-time use.
Embodiment
The chemical constitution and the processing condition of the antibiotic acrylic board of preparation stellerite: the stellerite ore that 1, produces with the Guangxi resource is the antiseptic-germicide main raw material, and raw ore is eluriated, and grinding and processing is to the 550-600 order; 2, with the 1g na-pretreated zeolite; 0.1M cupric nitrate 5ml, 0.1M zinc nitrate 5ml, 0.1M Silver Nitrate 10ml are that ratio is added successively, after under the insulation stirring reaction 2-3 hour, and room temperature held 2 hours; Washing gets the antibacterial agent of copper zinc-silver mixed load to neutral after the oven dry.Antibacterial effect is outstanding and have high characteristics of Guangxi Zeolite whiteness high purity after the stellerite modification, can be directly adds in the acrylic board base material with 5% mass ratio, through being processed into antibiotic acrylic board.
The technical process of preparation is: stellerite elutriation → dry ground → antibacterial modified → insulation, stirring → washing → drying → be mixed into antibiotic acrylic board base material → forming process → finished product.
Claims (4)
1. prepare the method for antibiotic acrylic board with stellerite, it is characterized in that: comprise the steps:
(1) with the stellerite ore be raw material, warp elutriation, grinding and processing are to the 550-600 order;
(2) again with the 1g na-pretreated zeolite; 0.1M cupric nitrate 5ml, 0.1M zinc nitrate 5ml, 0.1M Silver Nitrate 10ml are that ratio is added in the na-pretreated zeolite successively; After under the insulation stirring reaction 2-3 hour; Room temperature held 2 hours, washing get the stellerite antiseptic-germicide of copper, zinc, silver-colored mixed load to neutral after the oven dry;
(3) the above-mentioned stellerite antiseptic-germicide that makes is added in the acrylic board base material, mix, and then process the antibiotic acrylic board of stellerite.
2. method according to claim 1 is characterized in that: the interpolation mass ratio of stellerite antiseptic-germicide is: acrylic plate substrate ︰ stellerite antiseptic-germicide=100 ︰ 5.
