Description
Technical Field
The invention relates to the technical field of materials, in particular to an antibacterial, algae-proof and discoloration-preventing water culture tank material and a preparation method thereof.
Background
Fungi or algae in water have long plagued practitioners in the water culture and breeding field. For example, algae growth can create problems, where the algae can consume nutrients accumulated in the water and can be harmful to the hydroponic plants or animals. In the past, the treatment method generally comprises removing algae, or culturing algae in a container or adding quicklime into the algae for disinfection, but the method is not the fundamental method.
At present, practitioners develop water culture tank materials with the functions of preventing bacteria and algae to achieve the effect of preventing bacteria and algae from growing and breeding, so that the culture solution is protected. However, the prepared water culture tank material is usually prepared by adding an antibacterial and anti-algae additive into a base material, and because metal ions contained in the antibacterial and anti-algae additive change color when being exposed to light or heat, the color of a final product is easy to turn yellow, and the antibacterial and anti-algae effect is not durable.
Disclosure of Invention
Based on the technical problems in the background art, the invention provides an antibacterial, anti-algae and anti-discoloration water culture tank material and a preparation method thereof.
The invention provides an antibacterial and anti-algae discoloration prevention hydroponic tank material which comprises the following raw materials in parts by weight: 100 parts of polypropylene, 0.5-5 parts of anti-discoloration antibacterial anti-algae agent, 0-20 parts of inorganic filler, 1-10 parts of elastomer, 0.1-2 parts of coupling agent, 0.1-2 parts of antioxidant and 0-3 parts of additive;
the antitarnish antibacterial algaecide consists of silver-carrying zeolite prepared by an ion exchange method, copper zeolite and a silicon dioxide film coated on the surface of the silver-carrying zeolite.
Preferably, the polypropylene is a polypropylene having a melt flow rate of 0.5 to 60g/10min at 230 ℃ under a load of 2.16 kg.
Preferably, the discoloration-preventing antibacterial algicide is obtained by exchanging silver ions and copper ions with a mixed solution of zeolite, silver salt and copper salt, and then reacting with tetraethyl orthosilicate.
Preferably, the zeolite is
One or more of artificial zeolite, X-type artificial zeolite, Y-type artificial zeolite or mordenite.
Preferably, the silver salt is one or more of silver nitrate, silver sulfate or silver chloride, and the copper salt is one or more of copper nitrate, copper sulfate or copper chloride; preferably, the molar ratio of the amounts of silver salt and copper salt is 0.1-0.3: 0.1-3.
Preferably, the dosage ratio of the zeolite to the mixed solution of the silver salt and the copper salt is 0.5-1.5g:10mL, and the dosage ratio of the zeolite to the tetraethyl orthosilicate is 4-20g:1 mL.
Preferably, the inorganic filler is one or more of talcum powder, barium sulfate or calcium carbonate; the elastomer is a copolymer of ethylene and octene; the coupling agent is one or a mixture of silane coupling agent, titanate coupling agent or aluminate coupling agent; the antioxidant is one or a mixture of hindered phenol antioxidants or thioester antioxidants.
Preferably, the additives include lubricants, light stabilizers;
preferably, the lubricant is one or more of stearate, amide, silicone or metal soap, and the light stabilizer is one or more of triazine light stabilizer, benzotriazole, salicylate or hindered amine light stabilizer.
The invention also provides a preparation method of the antibacterial, algae-proof and anti-discoloration water culture tank material, which comprises the following steps: uniformly mixing raw materials of polypropylene, the anti-discoloration antibacterial anti-algae agent, the inorganic filler, the elastomer, the coupling agent, the antioxidant and the additive in a high-speed mixer, adding the raw materials into a double-screw extruder for melt extrusion, and then cooling and granulating to obtain the anti-bacterial anti-algae discoloration water culture tank material.
Preferably, the process conditions of the melt extrusion include: the first region is 180 ℃ minus 190 ℃, the second region is 190 ℃ minus 200 ℃, the third region is 200 ℃ minus 210 ℃, and the fourth region is 190 ℃ minus 200 ℃.
In the antibacterial, algae-preventing and discoloration-preventing water culture tank material, polypropylene is used as a matrix raw material, and a discoloration-preventing antibacterial agent is added, wherein the discoloration-preventing antibacterial agent comprises copper and silver active components, and has the characteristics of high efficiency prevention of algae growth by copper compounds and strong bactericidal capability by silver compounds, so that the polypropylene composite material is endowed with excellent antibacterial and algae-preventing activity on the basis of the original performance of the polypropylene material.
Furthermore, the discoloration-prevention antibacterial algaecide provided by the invention is prepared by exchanging silver ions and copper ions with a mixed solution of zeolite, silver salt and copper salt, and then adding tetraethyl orthosilicate for reaction, so that a layer of silicon dioxide film is covered on the surface of the silver-and copper-loaded zeolite, and the silicon dioxide film plays a role in protection, can anchor the silver and copper ions on ion exchange positions, fully reduces the dissolution rate of the silver and copper ions from a carrier, and prevents the silver ions from discoloring due to too early and too fast contact with light and heat and prevents the copper ions from being rapidly separated out, so that the material is prevented from discoloring due to water absorption. Therefore, the long-term and lasting algae-proof and antibacterial effects of the water culture tank material are ensured, and the possibility of color change of the water culture tank material is also prevented.
Detailed Description
Hereinafter, the technical solution of the present invention will be described in detail by specific examples, but these examples should be explicitly proposed for illustration, but should not be construed as limiting the scope of the present invention.
