Dimer acid modified alkyd resin and preparing method thereof

Abstract

The invention discloses a modified alcohol acid resin (R is aliphatic acid hydrocarbyl group; R1, R2, R3 and R4 are dimer acid hydrocarbyl group or hydrocarbyl chain) and making method of paint coating, which comprises the following steps: adopting plant oleic acid as raw material; using dimer acid manufactured by plant oleic acid to replace oleic acid; making polyol, polyacid, reflux solvent anddilute solvent as auxiliary material to synthesize the product.

Description

Dimer acid modified alkyd resin and manufacturing method thereof 1. Technical field The invention belongs to a coating semi-finished product and a manufacturing method thereof in the technical field of fine chemicals, and in particular relates to a modified alkyd resin and a manufacturing method thereof. 2. Background technology The usual alkyd resins are made by polymerizing vegetable oil or vegetable oleic acid with polyols and polyacids. The prepared coatings are generally dry. In recent years, in order to meet different performance requirements, many modified alkyd resin products have appeared, mainly including TDI (toluene diisocyanate), styrene, acrylic modified alkyd resin, such as "Modern Paint and Coating" 2002 03 issue discloses a kind of manufacture method of TDI modified alkyd resin, "Chemical Engineering" 2001 01 Issue, "Material Protection" 2000 08 and "Chemical Technology and Development" 2006 Volume 35 Issue 5 disclosed the production method of styrene-modi...
