Description
Technical Field
The invention relates to the field of painting materials, in particular to a water-based resin for waterproof oil painting pigments and a preparation method and application thereof.
Background
The water-repellent ability of the oil paint itself depends mainly on the natural resin or synthetic resin from which the oil paint is processed. However, due to the production technology, the water-based resin used by the existing oil painting pigment is often poor in waterproof performance, and the waterproof performance of the outdoor oil painting is restricted.
For oil paintings, particularly outdoor large oil paintings, due to wind, sunshine and rain, corresponding waterproof treatment is needed after the outdoor oil paintings are usually manufactured, labor and time are wasted, and if the outdoor large oil paintings are not properly treated, the oil paintings are damaged by rainwater once and are difficult to repair.
Disclosure of Invention
The invention aims to synthesize the water-based resin for the waterproof oil painting pigment. The specific technical scheme is as follows:
the water-based resin for the waterproof oil painting pigment is prepared from, by mass, 117-137 parts of distilled water or deionized water, 3-5 parts of alkylphenol polyoxyethylene ether, 0.9-1.1 parts of sodium dodecyl sulfate, 0.65-0.85 part of polyacrylamide, 55.3-57.3 parts of styrene, 48.0-50.0 parts of butyl acrylate, 1.0-1.7 parts of methyl methacrylate, 2.0-3.0 parts of acrylic acid, 0.8-1.0 part of ammonium persulfate and 3-5 parts of 25-28 wt% of an ammonia water solution, wherein the pH value of the resin is 7-8, and the viscosity of the resin is 210-250 mPa.
The invention also aims to provide a preparation method of the water-based resin, and the specific technical scheme is as follows:
a preparation method of water-based resin for waterproof oil painting pigment comprises the following steps: adding 3-5 parts of alkylphenol polyoxyethylene, 0.9-1.1 part of lauryl sodium sulfate, 0.65-0.85 part of polyacrylamide, 0.8-1.0 part of ammonium persulfate, and 137 parts of distilled water or deionized water into a reaction container in sequence by mass, stirring until the materials are completely dissolved, then adding 55.3-57.3 parts of styrene, 48.0-50.0 parts of butyl acrylate, 1.0-1.7 parts of methyl methacrylate and 2.0-3.0 parts of acrylic acid in sequence, and continuously stirring for 20-40 minutes to obtain an emulsion; stopping stirring, leading out or pouring out the emulsion from 2/5-2/3, heating to 90-100 ℃ while stirring, dropwise adding the led out or poured out emulsion to control the temperature to 90-100 ℃ so as to enable the reaction to be stable, controlling the temperature to 1-1.5 hours, and then keeping the temperature at 100-110 ℃ for 1-3 hours; and then adding 3-5 parts of 25-28 wt% ammonia water solution to adjust the pH value to 7-8, thus obtaining the water-based resin for the waterproof oil painting pigment.
Preferably, the temperature rise rate is 2-3 ℃/min.
The invention also aims to provide application of the waterborne resin. The specific technical scheme is as follows:
the water-based resin for the water-proof oil painting pigment is used as a resin raw material of the water-based oil painting pigment.
Preferably, the method for specific application thereof comprises the following steps:
(1) sequentially adding softened water, a dispersing agent, a wetting agent, a defoaming agent, ethylene glycol, titanium dioxide and stone powder into a dispersing container, dispersing for 10-30 minutes at the rotating speed of 800 plus materials of 1000 revolutions per minute, then sanding until the fineness of the pigment is 150 mu m, and pouring into a size mixing container;
(2) and (2) adding the aqueous resin, the film-forming polymer, the preservative and water into the size mixing container in the step (1), stirring for 20-40 minutes at the speed of 200 revolutions per minute of 120-.
Preferably, the dispersant is P-19, the wetting agent is CF-01, the defoamer is SPA-202, the preservative is CTX-3, and the film-forming polymer is 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate.
Preferably, the softened water, the dispersing agent, the wetting agent, the defoaming agent, the ethylene glycol, the titanium dioxide and the stone powder in the step (1) are respectively 300 parts, 1 part, 4 parts, 190 parts, 200 parts and 100 parts in parts by mass; the aqueous resin, the film-forming polymer, the preservative and the water in the step (2) are 470 parts, 17 parts, 3 parts and 120 parts by mass respectively.
The invention has the advantages of
The preparation process is safe and environment-friendly, the synthesized water-based resin can be infinitely mixed with water, no toxic or side effect is caused to oil painting pigment producers or users, and the oil painting pigment prepared by the water-based resin has unique waterproof performance and weather resistance after being naturally dried. The water-based resin greatly improves the water resistance and the washing resistance of the oil painting pigment. The oil painting works created by the oil painting pigment made of the resin have natural waterproof function after being naturally dried; especially for oil painting works finished outdoors, the oil painting works can be preserved for a long time without additional waterproof treatment.
