Abstract
The invention belongs to the field of water-based paint, and discloses a vinyl silicone oil modified resin oil-water separation net material, and a preparation method and application thereof. The oil-water separation mesh material is prepared by the following steps: mixing vinyl silicone oil modified resin, a curing agent and water to form a water dispersion system, depositing the hydrophobic coating vinyl silicone oil modified resin and the curing agent on the surface of a metal net through electrophoresis technology, and curing at high temperature to obtain the modified oil-water separation net. During the separation process of separating oil-water mixture, the water phase cannot permeate through the meshes and is trapped due to the hydrophobicity of the modified metal net; due to the lipophilicity of the modified metal net, the oil phase can penetrate through the meshes, and therefore the oil-water efficient separation is achieved. After the oil-water mixture is treated (acid leaching, alkali leaching and salt leaching) for 24 hours in various harsh environments, the separation efficiency of the separation mesh material on the oil-water mixture can still be kept above 99.5%.

The electrophoresis process control parameters are as follows: the temperature of the bath solution is 28 ℃, the pH value is 7.3, the voltage is 15V, the electrophoresis time is 15 seconds, and the total solid content of the vinyl silicone oil modified resin and the blocking curing agent is 13 percent.
(4) And (3) washing the iron net with a large amount of flowing clear water after electrophoresis, airing, and curing at the high temperature of 160 ℃ for 1 hour to obtain the vinyl silicone oil modified resin oil-water separation net material.
The vinyl silicone oil modified resin in the step (1) is prepared by the following steps:
(1.1)15 parts of vinyl silicone oil (5 mol% of vinyl), 0.2 part of azobisisobutyronitrile and 50 parts of ethylene glycol monomethyl ether acetate are mixed, stirred, heated to 100 ℃ and kept warm.
(1.2) dropwise adding a mixture of 6 parts of methyl methacrylate, 9 parts of butyl acrylate, 3 parts of styrene, 10 parts of hydroxypropyl methacrylate, 5 parts of dimethylaminoethyl methacrylate and 0.2 part of azobisisobutyronitrile at a constant speed for 1.5 hours, dividing the rest of azobisisobutyronitrile into two equal parts, dropwise adding one part of azodiisobutyronitrile for each hour, and finally continuing to perform heat preservation reaction for 2 hours;
(1.3) cooling to room temperature, adding lactic acid to neutralize until the pH value is 7.6, and obtaining the vinyl silicone oil modified resin.
The blocked curing agent in the step 1 is prepared by reacting 50 g of HDI tripolymer with 26 g of methyl ethyl ketoxime under the reaction condition that the methyl ethyl ketoxime is slowly dripped into HDI at 25 ℃, and is stirred and reacted for 24 hours.
The scanning electron microscope SEM schematic diagram of the cathode metal mesh iron mesh used in this example 1 is shown in fig. 1, the SEM image of the vinyl silicone oil modified resin oil-water separation mesh material obtained in this example 1 is shown in fig. 2, and it can be seen from fig. 1 and fig. 2 that the surface of the iron mesh without the electrophoretic deposition process is relatively smooth, the average pore size is 40 micrometers, after the treatment of the electrophoretic deposition process, the surface of the iron mesh is covered with a uniform polymer coating, and the coating thickness is 2 to 3 micrometers, so that the pore size of the iron mesh after the electrophoretic deposition is about 35 micrometers.
