It is a further object of the present invention to provide the preparation methods that a kind of long-acting bacteriostatic removes aldehyde diatom ooze wall material, including following step It is rapid:
(1) it by after diatomite coarse crushing, is added in nitric acid solution, being configured to diatomite weight percent is 20-30% Mixed liquor, after 30-60min is stirred by ultrasonic under the conditions of 60-80 DEG C, washing is dry to account for diatomite total weight to moisture Then diatomite and expanded vermiculite are sent into sintering furnace by 5-10%, after being to slowly warm up to 500 DEG C, roast 2-4h, be subsequently cooled to It 200 ± 10 DEG C, is pulverized after quenching to 200 mesh, it is spare;
(2) fresh Enteromorpha is caught, vacuum freeze drying is carried out after cleaning up, then with shell in inert gas shielding Lower 600-800 DEG C of sintering 2h pulverizes to 200 mesh after being cooled to room temperature, obtains mixed material A;It is spare;
(3) charred medicinal herb with its property retained after drying luffa vine, tea seed cake is dried, and is then mixed the luffa vine after charred medicinal herb with its property retained with tea seed cake and is sent Enter nano-level grinder to be ground, obtains mixed material B, it is spare;
(4) by step (2), (3), after mixing, ethanol in proper amount is added in mixed material A obtained, mixed material B respectively Then triethanolamine is added in ultrasonic disperse 10-20min, aluminate coupling agent stirs under the revolving speed of 200-300r/min 30min obtains mixed material C after washing is dry;
(5) mixed material C made from the diatomite, expanded vermiculite and step (4) after pulverizing step (1), which is sent into, to be divided Dissipate machine, it is pre-dispersed uniformly after, it is fine to add sodium sulfate of polyethenoxy ether of fatty alcohol, hydroxypropylcellulose, water soluble starch, wollastonite Peacekeeping suitable quantity of water under the revolving speed of 400-600r/min after heating stirring 30-60min, dries to obtain mixed material D;
(6) portland cement, kaolin, polypropylene fibre are added in high speed mixer, with stirring for 800-1000r/min It mixes speed and 30min is mixed, mixed material D is then added, after stirring 10min in advance, sodium carboxymethylcellulose, Arab is added Gum powder and suitable quantity of water, after high-speed stirred 30min, discharging it is dry to get.
Preferably, the pH value of nitric acid solution is 0.2-0.4 in step (1).
Further, the pH value of nitric acid solution is 0.3 in step (1).
Preferably, Enteromorpha, sintering temperature of the shell under atmosphere of inert gases are 700 DEG C in step (2).
Compared with prior art, the invention has the benefit that
(1) diatom ooze wall material prepared by the present invention is without containing the toxic organic solvents such as formaldehyde, volatile organic content pole Low, the hole compared with ordinary silicon diatomaceous earth increased significantly increase, and hole connectivity is good, through hydroxypropylcellulose, water soluble starch, wollastonite After fiber treatment, diatomite protective layer as diatomite surface formation layer of gel skeleton when adding water and stirring can be made, prevent it The hole of his raw material blocking diatomite, also has a certain degree of cohesiveness, is conducive to the compoiste adhering of diatomite Yu other raw materials, together When the cross-linking properties of diatomite and portland cement, kaolin, polypropylene fibre can be improved, keep diatom ooze obtained more stable, With better grasping force, it is not easy precipitated and separated, flexibility is good, and intensity is high, long-acting can remove the nuisances such as indoor formaldehyde, stupid Matter, the phenomenon that being less prone to cracking in use, fall off, easily lose powder, long service life.
(2) washed to remove after heating diatomite coarse crushing nitric acid solution in preparation method of the invention Impurity therein is removed, hole is dredged, is then 5-10% by diatomite drying to water content, then roasted at 500 DEG C, it can To remove organic impurities therein, moreover it is possible on the basis of keeping hole integrality, expand the hole of diatomite, have diatomite There is better adsorptivity.
(3) present invention is directed to local conditions, prepares diatom ooze as raw material after Enteromorpha, shell are handled, can Pollution problem is spread unchecked with solve local Enteromorpha and shell, and the cost of diatom ooze can be reduced.Enteromorpha is cheap and easy to get, solves The problem of Enteromorpha excessively blocks the fairway, and destroys marine ecosystems, seriously threatens inshore fishing, tourism development, turns waste into wealth, Not only resource has been saved, but also has protected environment.Shell is porous light, keeps diatom ooze quality fine and smooth as filler material, can not only fill Real paint film increases covering power, assigns diatom ooze and is not easy precipitating and good brushability, also has certain formaldehyde adsorption and metal The characteristic of the harmful substances such as ion.
(4) luffa vine belongs to agricultural waste material under normal circumstances, however itself has suppression well to common strain Bacterium activity, and changed after the luffa vine after charred medicinal herb with its property retained is mixed with tea seed cake, Enteromorpha conch meal with triethanolamine, aluminate coupling agent Property, the bacteriostasis property of the bactericidal property of tea seed cake, conch meal is combined with the bacteriostasis property of luffa vine, it is modified so that the mixing Object has more active sites, and insect prevention bacteriostasis property is more excellent, and it is covered to the diatomite for being loaded in ultramicro grinding, expansion jointly On vermiculite mixed material, the slow release of antibacterial agent may be implemented, have the effect of long-acting bactericidal, and antimicrobial component can be improved Stability and bioavilability.
(5) present invention uses sodium sulfate of polyethenoxy ether of fatty alcohol and hydroxypropylcellulose, water soluble starch, wollastonite fibre Mixed material C is handled, microvesicle, and sodium sulfate of polyethenoxy ether of fatty alcohol and hydroxypropyl fiber can be formed on its surface Element, water soluble starch, wollastonite fibre compounding, form a kind of protective layer of similar gels skeleton on mixed material surface, prevent Other raw materials block their hole, also have a certain degree of cohesiveness, and are conducive to its compoiste adhering with other raw materials, while can The cross-linking properties for improving they and portland cement, kaolin, polypropylene fibre keeps diatom ooze obtained more stable, has more Good grasping force, is not easy precipitated and separated, and flexibility is good, and intensity is high, is less prone to cracking in use, falls off, easily loses powder The phenomenon that, long service life.
(6) present invention uses gum arabic powder, sodium carboxymethylcellulose organic binder as binder, although having Machine binder, but because diatomite and expanded vermiculite surface form a kind of protective layer of similar gels skeleton, organic binder The hole that diatomite and expanded vermiculite will not be closed ensure that good adhesion substantially, it is ensured that diatom ooze is good Absorption property and bacteriostasis property, long-acting can remove the harmful substances such as indoor formaldehyde, stupid, preferably purify air, and be added A certain amount of portland cement, kaolin make diatom ooze obtained have better covering power and intensity.
