Problems solved by technology

[0002] Because alkyd resin has excellent durability, flexibility, and good brushability, it is widely prepared as anti-corrosion coating resin, which is used in vehicles, railways, large pipelines, construction and other fields; Medium, there are defects such as slow drying and easy yellowing, and the salt spray resistance of the coating is poor;
[0003] The flash point is an important basis for classifying the fire hazard of flammable liquids. Most of the solvents used in the existing alkyd resins are volatile flammable solvents, and the flash point is generally low, and it is easy to release a large amount of aromatic hydrocarbons, esters, and ketones after construction. Organic volatiles such as methionine pollute the environment and are also harmful to human health;
[0004] Existing alkyd resin coatings are mainly composed of long-oil semi-dry soy-acid alkyd resin, combined with 200# solvent oil, pigments and fillers, and drier; there are the following deficiencies: the product has a low flash point; Low safety; in the process of production, operation, transportation, storage and use, there are strict requirements on related production facilities, transportation vehicles, warehouse storage facilities and construction management; traditional alkyd resin coatings need to be used in large quantities in order to meet the construction conditions Organic solvents are used for dilution, so the VOC content is high, polluting the environment, requiring post-environmental protection treatment, and increasing costs

Abstract

The invention provides a high-flash-point safe alkyd anticorrosive coating and a preparation process thereof. The anticorrosive coating prepared by the invention is compounded by taking renewable high-iodine-value oleic acid alkyd resin as an adhesive and taking a high-flash-point solvent, emulsified water, a high-efficiency drier, titanium dioxide, nano barium sulfate and the like as pigments and fillers; linseed oil with a high iodine value and basic alkyd resin are used for preparing the oleic acid alkyd resin with a high iodine value, so that the compactness, dryness and water resistance of the coating are synchronously improved; the linseed oil with a high iodine value is prepared by limiting the content ratio of maleic anhydride, linseed oil and azodiisobutyronitrile, so that the hydrolytic stability of the resin is improved; the basic alkyd resin with stable gloss, gloss retention, water resistance and outdoor durability is prepared by limiting the contents of maleic anhydride, linoleic acid, benzoic acid, tung linoleic acid, pentaerythritol and isophthalic acid; and the high-iodine-value oleic acid alkyd resin is modified by hollow titanium dioxide microspheres with the particle size of 250-300nm, so that the compactness of the coating is improved, and the corrosion resistance is greatly enhanced.
