A kind of seawater pipeline anticorrosive paint and preparation method thereof
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of seawater pipeline anticorrosive paint and preparation method thereof.
Background technique
Marine corrosion refers to the corrosion that metal component occurs in marine environment.Marine environment is a kind of corrosion ring of complexity Border.Wherein in addition to the corrosion of seawater, microorganism, mushroom corrosion are also one of important component.Needle in the prior art It is general using toxic preservative is added in coating to the above problem, although certain anti-corrosion effect is achieved, also to sea Foreign ecological environment causes biggish broken ring, the especially water environment on seawater pipeline periphery.
Summary of the invention
The object of the present invention is to provide a kind of safe and non-toxic, high-efficient and lasting seawater pipeline anticorrosive paints.
For achieving the above object, the technical scheme adopted by the invention is that: a kind of seawater pipeline anticorrosive paint, by The raw material of following parts by weight are constituted:
The general formula of the piezoluminescence material are as follows:
The photocatalyst material is Ag doping modified nano-titanium dioxide.
Preferably, it is made of the raw material of following parts by weight:
Preferably, the length of the PP fiber is less than 1mm.
Preferably, the preparation method of the seawater pipeline anticorrosive paint, comprising the following steps:
(1) preparation of piezoluminescence material: bromo tetraphenyl ethylene and 4- aldehyde radical phenyl boric acid are dissolved in toluene, and four fourths are added Base ammonium bromide and wet chemical；After logical nitrogen 0.5h, tetrakis triphenylphosphine palladium is added, is heated to 90 DEG C of reactions for 24 hours；Reaction After, the reaction solution for being as cold as room temperature is poured into water, is extracted using ethyl acetate；Organic layer is dry with anhydrous sodium sulfate Afterwards, solvent is boiled off, is purified using silica gel column chromatography, is drenched and is inhaled as leacheate using n-hexane and methylene chloride mixed solvent, obtained To white product be piezoluminescence material；
(2) preparation of photocatalyst material: at normal temperature, a certain amount of nano-titanium dioxide being added in silver nitrate solution, Sodium carbonate liquor is added after reaction after a period of time, mixed solution is made；The mixed solution is straight under the irradiation of ultraviolet radiator Supernatant liquor is removed after standing to distill water washing to photochemical reaction is completed, lower layer is Ag doping modified nano-silica Titanium；
(3) modified natural glycan super absorbent resin, zinc acrylate resin and emulsified wax are emulsified 60-80 points together Clock adds phosphatide emulsifier, and it is stand-by that water-soluble emulsion is made；Again by piezoluminescence material, photocatalyst material, PP fiber, Organobentonite, propylene glycol are added in water-soluble emulsion, 100 DEG C at a temperature of, stir 15 points with 900 revs/min of speed Clock is to get finished product.
Beneficial effects of the present invention embody a concentrated reflection of:
(1) safe and non-toxic, effectiveness is lasting using photocatalyst material as antibacterial, sterilizing composition, to inhibiting microorganism attachment tool There is fabulous effect.
(2) piezoluminescence material is under the fluctuation impact of seawater, and pressure change can generate certain fluorescent effect, with nature Light matches can provide long-acting trigger condition for photocatalyst.
(3) using Ag doping modified nano-titanium dioxide as photocatalyst material, there is broader Absorber Bandwidth, so that light touches Catalytic material also has preferable activity under the catalysis of natural light.
(4) addition of PP fiber not only increases the mechanical performance of coating, while improving the roughness of coating surface, makes Obtaining photocatalyst material and piezoluminescence material has more exposed areas, improves the efficiency of the two.
Specific embodiment
The preparation method of seawater pipeline anticorrosive paint of the present invention:
(1) preparation of piezoluminescence material: bromo tetraphenyl ethylene and 4- aldehyde radical phenyl boric acid are dissolved in toluene, and four fourths are added Base ammonium bromide and wet chemical；After logical nitrogen 0.5h, tetrakis triphenylphosphine palladium is added, is heated to 90 DEG C of reactions for 24 hours；Reaction After, the reaction solution for being as cold as room temperature is poured into water, is extracted using ethyl acetate；Organic layer is dry with anhydrous sodium sulfate Afterwards, solvent is boiled off, is purified using silica gel column chromatography, is drenched and is inhaled as leacheate using n-hexane and methylene chloride mixed solvent, obtained To white product be piezoluminescence material, output capacity 88%；Since coating of the present invention is typically employed in seawater On pipe element, natural light is relatively poor.For this purpose, the activity in order to guarantee photocatalyst material, the present invention is added with piezoluminescence Material, the piezoluminescence material namely can be issued light by after external pressure stimulation, urge to provide for photocatalyst material Change source.The general structure of the piezoluminescence material are as follows:
(2) preparation of photocatalyst material: the extinction bandwidth in order to improve photocatalyst material plays visible light and fluorescence more Good catalytic action, better way are that photocatalyst material of the present invention uses Ag doping modified nano-titanium dioxide, It exactly utilizes and adulterates silver particles in nano-titanium dioxide, to improve the extinction bandwidth of nano-titanium dioxide, make it non-ultraviolet Also there is preferable activity under environment.The present invention controls the PH numerical value of solution, by one at normal temperature using photochemical precipitation method Quantitative nano-titanium dioxide is added in silver nitrate solution, strong stirring, and it is molten that sodium carbonate is added after reaction after a period of time Mixed solution is made in liquid；The mixed solution under the irradiation of ultraviolet radiator until complete photochemical reaction, it is quiet to distill water washing Removing supernatant liquor is postponed, lower layer is Ag doping modified nano-titanium dioxide.Ag doping modified Nano two of the present invention Titanium oxide still has high activity under visible light environment, reduces the catalysis difficulty of photocatalyst material.
(3) modified natural glycan super absorbent resin, zinc acrylate resin and emulsified wax are emulsified 60-80 points together Clock adds phosphatide emulsifier, and it is stand-by that water-soluble emulsion is made；Again by piezoluminescence material, photocatalyst material, PP fiber, Organobentonite, propylene glycol are added in water-soluble emulsion, 100 DEG C at a temperature of, stir 15 points with 900 revs/min of speed Clock is to get finished product.
