Abstract

The invention relates to chlorinated alkyd resin and a preparation method thereof. The preparation method comprises the following steps: preparing alkyd resin by taking glycerinum, pentaerythritol, phthalic anhydride, soya bean oil fatty acid and rosin as raw materials; after dilution, introducing chlorine to chlorinate to obtain the chlorinated alkyd resin. The chlorinated alkyd resin provided by the invention has the advantages of low cost, good paint-making performance, good preservative effect, flame retardance and the like. The preparation process of the chlorinated alkyd resin is simple and convenient, mild in condition and suitable for industrialized production; the chlorinated alkyd resin has a wide application prospect in the field of coating.

Description

Technical field: [0001] The invention relates to a chlorinated alkyd resin and a preparation method thereof. The chlorinated alkyd resin has good corrosion resistance. Background technique: [0002] Alkyd resin has become the largest and most widely used synthetic resin in the coatings industry because of its wide source of synthetic raw materials, flexible formula, simple process, excellent comprehensive performance of coating film, and can be endowed with various performance characteristics through various modifications. Alkyd paint formulated by alkyd resin is still one of the most important paint varieties in the paint market so far, and its output accounts for about 20% to 25% of the total paint industry. Alkyd paint based on alkyd resin has the advantages of good self-drying property, low price, diverse and simple construction, and is widely used as decorative anti-corrosion materials on indoor and outdoor buildings, steel equipment, machines and other equipment.
