In above extinction fever ball, the extinction heating surface is made of polyethylene film.
The above extinction fever ball in, the polyethylene film with a thickness of 0.2~0.5mm.
The present invention also provides a kind of methods for preparing extinction fever ball, which comprises by Alathon, ethylene It according to mass ratio is that 44:37~44:32~41:28 is added in mixing machine with the copolymer of alkene, polyacrylate, 175 2~5min of hybrid reaction at a temperature of~182 DEG C, with extruder temperature is 179~187 DEG C, blow-up ratio is 2.5~3.0, is led Draw and generates heat ball than blow molding under conditions of being 4~6 to get to extinction.
In the above-mentioned methods, it is 0.910 to 0.930g/ that the Alathon, which includes: the density (d) of 5 to 95 quality %, The ethene polymers (A) that cm3 and HLMFR is 0.1 to 3.0g/10 minute；And 5 to 95 quality % density (d) be 0.955 to The ethene polymers (B) that 0.965g/cm3 and HLMFR is 10 to 100g/10 minutes.
In the above-mentioned methods, the polyacrylate is prepared by following methods: by acrylic acid, SE-10 emulsifier, acrylic acid Different monooctyl ester, Macrogol 600, polyethylene glycol methacrylate-styrene polymer, 819 photoinitiators and aluminium-magnesium silicate are added in reaction kettle, Mixing speed is 96~110r/min, reacts 28min under the conditions of 28~36 DEG C of maintenance system temperature, product is through 36W LED lamplight According to 45s, 100W lamp and high pressure mercury 34s, 1000W 4~13s of lamp and high pressure mercury, crush to get polyacrylate is arrived.
In the above-mentioned methods, acrylic acid, SE-10 emulsifier, Isooctyl acrylate monomer, Macrogol 600, polyethylene glycol methyl The mass ratio of acrylate, 819 photoinitiators and aluminium-magnesium silicate is 8:29~37:27~41:3~9:9~18:0.3~0.7: 16~23.
The present invention also provides above-mentioned extinction fever balls to inhibit the application in Eichhornia crassipes growth.
Compared with prior art, present invention has the advantage that
Extinction fever ball provided by the invention includes hollow ball and extinction heating surface, and total quality is light, may float on water On face, thermal energy is converted by solar energy using the extinction heating surface on surface, ambient temperature is improved, inhibits water hyacinth Growth.
Detailed description of the invention
Fig. 1 is schematic diagram (wherein, the 1- extinction heating surface of extinction fever ball of the invention；2- hollow ball).
Specific embodiment
The following examples can make those skilled in the art that the present invention be more fully understood, but not limit in any way The present invention.
In the present invention, extinction generates heat ball using hollow ball as structural support, and the density of the hollow ball is smaller, After a large amount of spheres are thrown into water, it can quickly be sprawled in the water surface, so that the sunny slope for being wrapped in the polyethylene film of spherome surface is fast Speed absorbs solar energy, and generates heat, increases ambient temperature, when temperature is more than water hyacinth suitable growth temperature, It can inhibit its growth.
In some implementations, the density of hollow ball is in 0.5~0.8g/cm3Between, when the density mistake of density hollow sphere Hour, it is easier to drift out the water surface, when the density of hollow ball is greater than 0.8g/cm3When, then hollow ball may not be able to swim in the water surface On, and then the effect quickly to absorb solar energy is not achieved.
In some embodiments, the diameter of hollow ball is between 10cm-15cm, when the diameter of hollow ball is less than 10cm When, sphere specific surface area is excessive, extinction amount increases, and sphere and the direct gap of sphere reduce, reduce water body dissolved oxygen amount, leads to water body Surface temperature is excessively high, generates anaerobic environment, is easy to breed harmful bacteria.
The extinction heating surface of extinction fever ball is made of polyethylene film.In some embodiments, polyethylene film is equal by ethylene Polymers, is made for two or three in polyacrylate the copolymer of ethylene and alkene, with a thickness of 0.2~0.5mm, when poly- second When the thickness of alkene film is less than 0.2mm, sphere aging speed is too fast, when the thickness of polyethylene film is greater than 0.5mm, generates resource wave Take.
