A kind of alkyd resin and preparation method thereof

Abstract

The invention discloses an alkyd resin, which comprises the following components in terms of mass percentage: 5-25% of cyclohexane 1,2-dicarboxylic acid diisononyl by-product; 20-30% of polyhydric alcohol; 20-35% polybasic acid; 5-20% monobasic acid; 0.01-1% color reducer; 0.01-5% reflux solvent; 10-25% dilution solvent; cyclohexane 1,2-dicarboxylic acid The diisononyl ester by-product comprises 5-15% nonanol by mass percentage, 5-15% nonanoic acid, 25-35% nonyl nonanoate, 25-35% hydroxymethyl dinonyl ester, 5-15% aldol condensate from nonanal, 5-15% high carbon ester from nonanoic acid. The alkyd resin of the invention can effectively utilize the by-products of DINCH, avoid subsequent by-product treatment costs, reduce environmental pollution, and can prepare coatings with high solid content in construction, high gloss and high vividness of image.

Description

Technical field [0001] The present invention relates to the field of polymer synthesis, particularly alcoholic resin and a preparation method thereof. Background technique [0002] DINCH (cyclohexane 1,2-dimethylene) is a common chemical raw material that will accompany a large number of by-products when producing DINCH, which will damage the environment, and the general treatment method is to increase subsequent. The processing process treats its by-products, thereby producing various processing costs; at the same time, the coating prepared by the existing resin is insufficient, the gloss is not high, and the premium premium is poor. [0003] There is an urgent need for a by-product that can effectively utilize DINCH, eliminating the renewal of by-product treatment cost, reducing environmental pollution, can prepare a coating of coating, high gloss, high gloss, high gloss, and preparation Method to solve the above technical problems. Inventive content [0004] In order to solve...

AI Technical Summary

Problems solved by technology

[0002] DINCH (diisononyl cyclohexane 1,2-dicarboxylate) is a common chemical raw material. During the production of DINCH, a large number of by-products will be produced, which will cause damage to the environment. The general treatment method is to increase the subsequent Therefore, various treatment costs will be incurred; at the same time, the coatings prepared by existing resins have one or more defects such as insufficient solid content, low gloss, and poor distinctness of image.
