Abstract
The invention belongs to oil removal technical field of coatings, more particularly to construction drainage pipe oil removal coating and preparation method thereof, the acrylic acid for being 100: 110: 30 by mass ratio, a concentration of 40% sodium hydrate aqueous solution and water carries out the obtained acrylates of neutralization reaction, starch is added at 30~40 DEG C and potassium peroxydisulfate is allowed to polymerize at 60~90 DEG C, wherein the mass ratio of starch and potassium peroxydisulfate and acrylic acid is 20: 2: 100, again obtained polymer is placed in grind after water swelling in the water of 100 times of acrylic acid and be slurried, and the coating that 85% alcohol is mixed into is added after the sieving of 300~500 mesh, wherein alcohol dosage and the ratio of acrylic acid are 80: 100.Construction drainage pipe oil removal coating provided by the invention, is sprayed on the inner surface of various tubing, and spraying position oil stain, which is fallen, meets wet meeting Automatic-falling above, and spraying in regular one month or so is primary, solves the problems, such as that the pipeline oil removal of oily wastewater prevents peculiar smell.
Description
Technical field
The invention belongs to oil removal technical field of coatings, and in particular to construction drainage pipe oil removal coating and preparation method thereof.
Background technology
With city and the development of urbanization, hotel, dining room scale be growing, quantity day is more, produces therewith
Raw food and drink waste water amount is increasing.Catering trade oily water refers to the sewage of catering industry be discharged into sewer pipe in operation,
Its main feature is that (TSS CODs (COD) concentration and content are high for animal and plant fat (FOG), total suspended particles.
It mainly has following three big directly harm：
First, block pipeline:A large amount of grease and residue are easily adhered on drainage pipeline wall, pipeline reality of accumulating over a long period to obtain
Circulation area is smaller and smaller, and displacement is reduced rapidly with flow velocity, eventually forms blocking, according to the data of closing, each metropolitan district in China
Domain have daily places up to a hundred caused by grease line clogging due to need dredging replace, caused by economic loss it is huge.
Second, corrosion pipeline and generate peculiar smell:Under chemistry and biochemical action, the time pushes away the grease accumulated in pipeline
Mordant aliphatic acid is decomposed and generated to shifting gradually, this not only can corrosion pipeline, but also pungent unpleasant peculiar smell can be produced.
Third leads to public sewage disposal failure:A large amount of grease finally enters sewage treatment plant by pipe network and makes pair
The very sensitive biological bacteria of grease largely degenerates, is dead, and effluent quality is caused to be decreased obviously and polluted to lower receiving water body.
The problem of pipeline oil removal of the first, second therein oily wastewater of catering trade for a long time de-tastes all is to be badly in need of
Solution and the hang-up that cannot thoroughly solve.The existing material of drainage pipe material for building on the market generally has a plastic tube, metal tube and multiple
Close three kinds of materials of pipe.The above different materials can not all solve the problems, such as that the pipeline oil removal of oily wastewater prevents peculiar smell simultaneously.Therefore
The drainage pipe material for building of brand new technical development of new oil removal coating need to be taken.
Invention content
It is an object of the invention to overcome disadvantages mentioned above, one kind is provided and is sprayed on nontoxic, nothing on construction drainage pipe internal surface
The paint without adhesion to oil of taste.
Specific technical solution is：
Construction drainage pipe oil removal coating has following methods to prepare gained：
（1）It is formulated into according to mass ratio 100: 110: 30 by acrylic acid, the sodium hydrate aqueous solution that mass concentration is 40% and water
Row reaction, obtains acrylates；
（2）At 30~40 DEG C, starch and potassium peroxydisulfate are added, is then heated at 60~90 DEG C and polymerisation occurs, institute
The mass ratio of the starch and potassium peroxydisulfate and acrylic acid stated is 20: 2: 100；
（3）Obtained polymer is added in water again, the dosage of water is 100 times of acrylic acid quality, polymer absorption expansion
Grinding is slurried afterwards, and is sieved through 300~500 mesh；
（4）The coating that the alcohol of concentration 75~95% is mixed into is added, the wherein mass ratio of alcohol dosage and acrylic acid is
50~100: 100.
Construction drainage pipe oil removal coating provided by the invention, is sprayed on the inner surface of various tubing, sprays position oil stain
Fall met above it is wet can Automatic-falling, spraying in regular one month or so is primary, solve oily wastewater pipeline oil removal prevent it is different
The problem of taste.
Specific implementation mode
It is described in conjunction with the embodiments the specific implementation mode of the present invention.The acrylic acid, dense for being 100: 110: 30 by mass ratio
Degree carries out the obtained acrylates of neutralization reaction for 40% sodium hydrate aqueous solution and water, and starch is added at 30~40 DEG C
It is allowed to polymerize at 60~90 DEG C with potassium peroxydisulfate, wherein the mass ratio of starch and potassium peroxydisulfate and acrylic acid is 20: 2:
100, then obtained polymer is placed in grind after water swelling in the water of 100 times of acrylic acid and is slurried, and through 300~500
The coating that 85% alcohol is mixed into is added after mesh sieving, wherein alcohol dosage and the ratio of acrylic acid is 80: 100.
Mechanical brushing and abrasive jet cleaning are used before applying construction drainage pipeline, inner wall of the pipe is made to reach the mark of spraying
It is accurate.
First paint without adhesion to oil is sent in spray equipment when coating, this spray equipment is sprayed with one or several
Mouth.When it enters in pipeline, it advances while spraying paint without adhesion to oil, and spray pressure is 14 ~ 21 MPa, and pipe is generally solid
Fixed not dynamic formula, depends on the nozzle specially used device in spraying arms.Coating layer thickness in pipe is by spray pressure, the number of material spray
It is determined with pipe relative velocity with spraying arms.Spraying in one month or so is primary.
Claims (1)
