Abstract

The invention relates to liquid alkyd resin and a preparation method thereof. The liquid alkyd resin comprises the following raw materials: oil, rosin, benzoic acid, polyatomic alcohol, waste, solvent oil and the like. The preparation method comprises the following steps of: adopting recovered waste and old plastic and chemical-fiber industrial waste as main raw materials, adding all auxiliary materials, generating polyesterification reaction in a reaction kettle, then carrying out dilution, and finally carrying out filtering to prepare a finished liquid alkyd resin product. In the invention, the waste plastic is utilized for preparing the liquid alkyd resin, the wastes become valuables, the technical process is simple and is easy to operate, the mode for utilizing heat-conducting oil for heating is safer and more energy-saving, and the application range is wide.

Description

technical field

[0001] The invention belongs to the technical field of paint and paint preparation, and in particular relates to a liquid paint used for the coating of automobiles, ships, machinery, and steel structure houses, as well as the surface treatment and spraying of various metals such as steel pipes, steel wire ropes, and standard parts. Alkyd resins and methods for their preparation. Background technique

[0002] Polyols and polybasic acids can undergo polycondensation reactions, and the resulting polycondensate macromolecular main chain contains many ester groups (-COO-), and this polymer is called polyester. In the paint industry, polyester resins modified with fatty acids or oils are called alkyd resins. According to the number and structure of double bonds in fatty acid (or oil) molecules, it can be divided into three types: dry, semi-dry and non-dry. Drying alkyds cure in air; non-drying alkyds are mixed with amino resins and cured by heating. After the al...
