In the invention, the alkyd resin protective coating is not easy to dry when the dosage of the alkyd resin is too large, and the film cannot be formed and the paint film performance is poor when the dosage of the alkyd resin is too small. In the invention, the alkyd resin is preferably prepared from natural vegetable oil through a high-temperature reaction. In the invention, in the high-temperature reaction process, the natural vegetable oil is subjected to alcoholysis and then polymerization. In the present invention, the natural vegetable oil preferably includes one or more of soybean oil, linseed oil and cottonseed oil, and more preferably soybean oil, linseed oil or cottonseed oil. In the invention, the temperature of the high-temperature reaction is preferably 180-200 ℃, and more preferably 185-195 ℃; the high-temperature reaction time is preferably 14-15 h, and more preferably 15 h. After the high-temperature reaction is finished, the invention preferably also comprises the steps of adding diethylene glycol butyl ether and/or diethylene glycol methyl ether solvent to adjust the viscosity of the obtained resin; in the invention, the viscosity of the alkyd resin is preferably 250-350 s (coating-4 viscometer, 25 ℃). The paint prepared by taking the alkyd resin as a film forming substance has a higher flash point than a paint prepared by directly taking natural vegetable oil as a raw material, and the alkyd resin protective paint provided by the invention has good adhesive force, flexibility, alkali resistance, acid resistance, wear resistance and weather resistance, is high in hardness, smooth and fine in paint film, non-toxic and pollution-free, and can effectively prolong the service life of the paint film of the alkyd resin protective paint.
In the invention, on the basis of the weight parts of the alkyd resin, the raw materials for preparing the high-flash-point alkyd resin protective coating comprise 15-20 parts of titanium dioxide, preferably 16-20 parts, and more preferably 16 parts, 17 parts, 18 parts, 19 parts or 20 parts.

In the invention, the titanium dioxide is preferably rutile type titanium dioxide, and more preferably chloride rutile type titanium dioxide. According to the invention, the titanium dioxide is used in combination with other raw materials, so that the performance of the alkyd resin protective coating can be improved.
In the invention, the raw materials for preparing the high flash point alkyd resin protective coating comprise, by weight, 5-15 parts of barium sulfate, preferably 6-15 parts of barium sulfate, and more preferably 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts or 15 parts of barium sulfate. In the present invention, the particle size of the barium sulfate is preferably 1100 to 1300 mesh, more preferably 1150 to 1250 mesh, and most preferably 1200 mesh. In the present invention, the barium sulfate functions as a filler; the film forming effect of the alkyd resin protective coating can be influenced by too much barium sulfate, and the mechanical property of a paint film of the alkyd resin protective coating can be influenced by too little barium sulfate. The invention uses the barium sulfate and other raw materials in a matching way, and can improve the performance of the alkyd resin protective coating.
In the invention, based on the weight parts of the alkyd resin, the raw materials for preparing the high-flash-point alkyd resin protective coating comprise 5-10 parts of alcohol ether solvent, preferably 6-10 parts, and more preferably 6 parts, 7 parts, 8 parts, 9 parts or 10 parts.

According to the invention, the fumed silica is used in combination with other raw materials, so that the performance of the alkyd resin protective coating can be improved.
In the invention, the raw materials for preparing the high flash point alkyd resin protective coating comprise 0.2-0.4 part of wetting agent, preferably 0.22-0.4 part, more preferably 0.25 part, 0.3 part, 0.35 part or 0.40 part by weight of alkyd resin. The present invention is not particularly limited with respect to the specific kind of the wetting agent, and any wetting agent known in the art, such as silicone oil, may be used. In the invention, the wetting agent is used for wetting pigment and filler, so that the grinding efficiency of titanium dioxide and barium sulfate and the coating of alkyd resin on other raw materials are improved, and the raw materials such as titanium dioxide and barium sulfate are prevented from flooding; too much of the wetting agent can cause shrinkage cavity of the alkyd resin protective paint film, and too little of the wetting agent can cause the paint film of the alkyd resin protective paint to be colored. The wetting agent is matched with other raw materials for use, so that the performance of the alkyd resin protective coating can be improved.
In the invention, the raw materials for preparing the high flash point alkyd resin protective coating comprise 0.3-0.5 part of dispersant, preferably 0.35-0.5 part, more preferably 0.35 part, 0.4 part, 0.45 part or 0.5 part by weight of alkyd resin.

In the present invention, the dispersant functions to disperse the pigment filler; when the amount of the dispersant is too much, the drying of a paint film of the alkyd resin protective paint is slow, and when the amount of the dispersant is too little, the paint film of the alkyd resin protective paint is loose and the paint is precipitated. The invention uses the dispersant and other raw materials in a matching way, and can improve the performance of the alkyd resin protective coating.
In the invention, the raw materials for preparing the high flash point alkyd resin protective coating comprise, by weight, 0.7-1 part of a drier, preferably 0.75-1 part, more preferably 0.75 part, 0.8 part, 0.85 part, 0.9 part, 0.95 part or 1 part of an alkyd resin. In the invention, the drier comprises one or more of metal oxide, metal salt and rare earth drier; the metal in the metal oxide and metal salt independently comprises cobalt, manganese, iron, zinc or calcium. In the invention, the drier is used for accelerating the drying of a paint film of the alkyd resin protective paint; the alkyd resin protective coating is easy to crust when the usage amount of the drier is too much, and the paint film of the alkyd resin protective coating is not easy to dry when the usage amount is too little. The invention uses the drier and other raw materials in a matching way, and can improve the performance of the alkyd resin protective coating.
In the invention, the raw materials for preparing the high flash point alkyd resin protective coating comprise 0.2-0.3 part of anti-skinning agent, preferably 0.22-0.3 part, more preferably 0.22 part, 0.24 part, 0.26 part, 0.28 part or 0.3 part by weight of alkyd resin. The invention has no special limitation on the type of the anti-skinning agent, and the anti-skinning agent well known in the art can be adopted, such as methyl ethyl ketoxime. In the invention, the anti-skinning agent is used for preventing the alkyd resin protective paint from skinning during storage; the anti-skinning agent is used in an excessive amount, so that a paint film of the alkyd resin protective paint is not dried, and the anti-skinning effect cannot be achieved due to the use of an excessive amount. The anti-skinning agent is matched with other raw materials, so that the performance of the alkyd resin protective coating can be improved.
The alkyd resin protective coating is prepared by taking alkyd resin as a main body, adding an alcohol ether solvent, titanium dioxide, barium sulfate and fumed silica, and under the action of a wetting agent, a dispersing agent, a drier and an anti-skinning agent, the obtained alkyd resin protective coating is high in flash point and is safer in the production, transportation and use processes; excellent acid resistance, alkali resistance, weather resistance and other properties; and the toxicity is low, and the environment is protected.
