Description
Technical field
The present invention relates to building material field, particularly a kind of fungi-proofing plasterboard.
Background technology
Nano zine oxide has extremely strong oxidation activity, can destroy biological activity and the metabolism breeding function of bacterium, thereby reach fungi-proofing object.In addition, nano zine oxide, under sunlight especially ultraviolet irradiation, can decomposite the electronegative electronics moving freely voluntarily, and leaves the hole of positively charged, this hole activates airborne oxygen for active oxygen, and active oxygen can kill most of pathogenic bacterias and virus.Nano zine oxide is added to compound, can plays and kill or the effect of anti-bacteria breeding, but because nano zine oxide has the features such as the large and specific surface energy of specific surface area is large, self easily reunites; On the other hand, surface of nanometer zinc oxide polarity is stronger, is difficult for dispersedly in medium, and this has just greatly limited the performance of its nano effect.Therefore nano oxidized zinc solution being carried out before application necessary processing is the key that fungi-proofing plasterboard keeps good fungi-proofing performance.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of fungi-proofing plasterboard and preparation method.
Fungi-proofing plasterboard formula is as follows:
(1) gypsum: 45～47 parts
(2) sand: 15～17 parts
(3) the anti-microbial inoculum of nano zine oxide: 12～14 parts
(4) polyamide resin: 1.5～2.5 parts
(5) magnetized water: 22～24 parts
The anti-microbial inoculum of nano zine oxide is made by following manner:
Ammoniacal liquor is added drop-wise in zinc nitrate solution, makes solution system pH value be greater than 9, then obtain precipitation with funnel, and with deionized water washing sediment repeatedly, until the pH value of system approaches 7; Maintain the temperature at 50 DEG C, to precipitation in successively add concentration be 0.95mol/L salpeter solution stir, between system pH to 3.5～4.1, can obtain nano oxidized zinc solution.
Anti-nano zine oxide microbial inoculum is magnetized to processing, and magnetizing equipment electric current adopts direct current, and the anti-microbial inoculum of nano zine oxide magnetizes in latter 12 hours and must finish using.
Nano oxidized zinc solution is after magnetization, and the elongated or bond angle of the key of nano zine oxide structure changes, and causes nano zine oxide intermolecular attraction to diminish, and magnetization surface of nanometer zinc oxide tension force is less, and it is active corresponding also larger, is easy to combine with gypsum molecule.Table 1 is surface tension test data table, reflects that nano zine oxide magnetization rear surface tension force obviously diminishes in table.
Table 1 surface tension test data table
Nano zine oxide itself is exactly a small magnet, and because opposite pole is inhaled mutually, thereby in ortho-water, many nano zine oxides will be inhaled first mutually, connect into huge " molecular grouping ", and this " molecular grouping " can weaken the multiple physicochemical property of nano zine oxide.Compared with large molecular grouping, the physical and chemical activity of unit molecule nano zine oxide is very strong, but the unit molecule in ortho-water is little, its activity is not high, in compound mix process, nano zine oxide can not be fully combined with gypsum molecule, thereby has affected germ resistance, and magnetization can improve antibacterial effect effectively.
Accelerate because magnetized water makes the hydration reaction of gypsum, shorten the time of coagulation of gypsum, and the early strength of plasterboard is corresponding improve also, thereby has also reduced its early stage tiny crack quantity, so magnetized water can improve the intensity of plasterboard.Table 2 is ortho-water and Magnetized water plasterboard intersection contrast strength trial, reflects that Magnetized water plasterboard intensity obtains certain raising in table.According to table 2 test situation, best magnetizing parameters is selected as follows: magneticstrength is 270MT, and discharge is 1500L/h.
Table 2 ortho-water and Magnetized water plasterboard intersection contrast strength trial
The fungi-proofing agent content of nano zine oxide is determined according to test.As can be seen from Table 3, along with the increase of the anti-microbial inoculum consumption of nano zine oxide, antibiotic rate improves.The sterilization rate of contact 4h, higher than contact 1h, illustrates that the anti-microbial inoculum of nano zine oxide can continue sterilization within a certain period of time.But along with the increase of the anti-microbial inoculum consumption of nano zine oxide, cost increases, and is unfavorable for practical application.And as can be seen from Table 3, in the time that the anti-microbial inoculum of nano zine oxide is 12 parts, sterilization rate also reaches 92.35% left and right, then increase the consumption of the anti-microbial inoculum of nano zine oxide, meaning is not very large, and has increased cost.Comprehensive anti-microbial property and cost factor, the fungi-proofing agent content of nano zine oxide is defined as 12～14 parts.
The impact of the anti-microbial inoculum consumption of table 3 nano zine oxide on anti-microbial property
| The anti-microbial inoculum consumption of nano zine oxide (part) | Contact 1h sterilization rate (%) | Contact 4h sterilization rate (%) |
| 0 | 1.96 | |
| 10 | 85.86 | 90.53 |
| 12 | 92.35 | 94.28 |
| 14 | 93.32 | 95.95 |
| 16 | 93.56 | 96.71 |
In order to improve cohesive force, be beneficial to mixing and moulding, add polyamide resin is binding agent.Polyamide resin volume will directly have influence on workability and the mechanical property of prepared insulation compound.Volume is very few, does not reach result of use; Volume is too much uneconomical again.Table 4 is the impact of different addition quantity polyamide resin on fungi-proofing plasterboard performance.In table, show that compound is slightly dispersion state in the time that polyamide resin volume is little, when mixing, fundamental sensation is less than viscosity.Along with the increase gradually of polyamide resin volume, the workability of compound progressively improves, and in the time that polyamide resin volume is 1.5 parts, the cohesiveness of compound can reach the requirement of construction, and serviceability has showed comparatively superiorly.Along with the increase of polyamide resin volume, the ultimate compression strength of compound, folding strength, pressure cut cohesive strength and full hydraulic pressure is cut totally all risings to some extent of cohesive strength, illustrates that the adhesive aggregation performance of compound is progressively improved.According to test-results, polyamide resin Determination of quantity is 1.5～2.5 parts.
The impact of table 4 different addition quantity polyamide resin on fungi-proofing plasterboard performance
The made fungi-proofing plasterboard of the present invention has the advantages that fungi-proofing performance is good, intensity is high.
