Problems solved by technology

Its film-forming base material is not flame-retardant, but by adding a large amount of flame-retardant pigments and fillers to achieve the purpose of flame-retardant and fire-proof. The decorative effect of the coating is poor, and it is almost impossible to obtain a flame-retardant and fire-resistant coating film with a transparent decorative effect.

Abstract

The invention belongs to the technical field of chemical engineering and especially discloses a flame-retardant alkyd resin. The flame-retardant alkyd resin comprises: by weight, 19.0 to 22.0% of soya fatty acid, 8.2 to 12.2% of pentaerythritol, 4.5 to 8.5% of tetrabromobisphenol A, 0.2 to 0.8% of maleic anhydride, 28.5 to 34.5% of tetrabromophthalic anhydride, 0.05 to 0.2 of at least one color subtraction agent, 0.05 to 0.2% of an antioxidant, 2.00 to 5% of refluxing xylene, and 24 to 28% of at least one dilute solvent. The flame-retardant alkyd resin has strong flame resistance. The preparation method of the flame-retardant alkyd resin is simple.

Description

technical field [0001] The invention relates to a coating in the field of chemical industry, in particular to a flame-retardant alkyd resin used for the coating. Background technique [0002] Alkyd resin coatings have the characteristics of good film adhesion, brightness, and fullness. They are generally organic polymer resins made from organic chemical raw materials such as oil (or oleic acid), polyols, and polyacids through condensation chemical reactions. The polybasic acid used in the synthesis of alkyd resins is mostly phthalic anhydride (PA, referred to as phthalic anhydride), and the commonly used polyols are ethylene glycol, glycerin, pentaerythritol, trimethylolpropane, etc. Alkyd resin coatings are the main film-forming substances of traditional blending paints, wood paints and enamel paints. The coatings produced by the synthesis of alkyd resins from commonly used raw materials have poor flame retardancy and are easy to decompose and burn at higher temperatures. G...
