Problems solved by technology

Alkyd resin has a broad market, but the traditional alkyd paint in the prior art has slow drying and low hardness. In order to meet the market and meet customer requirements, the company decided to develop a fast-drying alkyd resin. , Gloss and color retention are greatly improved compared with the previous traditional alkyd resin

Abstract

The invention discloses quick-dried alkyd resin and a preparation method thereof. The quick-dried alkyd resin is prepared from the following components in parts by weight: 17-22 parts of linoleic acid, 7-12 parts of benzoic acid, 9-12 parts of pentaerythritol, 16-22 parts of phthalic anhydride, 3-6 parts of a backflow solvent and 32-40 parts of a diluted solvent. By adopting the alkyd resin disclosed by the invention, the hard drying time of conventional alkyd resin is shortened to be 8 hours from the conventional 24 hours, so that the construction period of users is shortened. Compared with paint prepared from conventional alkyd resin, the quick-dried alkyd resin is relatively rapid to dry, relatively better in hardness, relatively excellent in mechanical property and relatively high in light and color retention property.

Description

Technical field: [0001] The invention belongs to the technical field of paint chemical industry, and in particular relates to a quick-drying alkyd resin and a preparation method thereof. technical background: [0002] A type of coating that uses alkyd resins made of polyols, polyacids and drying vegetable oils as the main film-forming substance is called alkyd resin paint. This kind of paint has good construction performance and can be dried at room temperature to form a film. The film is bright and plump, with strong adhesion, flexibility, firmness and not easy to age. In addition, alkyd resins can also be blended into a variety of distinctive coating products to meet different needs by taking advantage of the good miscibility of alkyd resins with other resins. Widely used in the finishing of buildings, bridges, ships, vehicles, instruments, meters, etc. Alkyd resin has a broad market, but the traditional alkyd paint in the prior art has slow drying and low hardness. In o...
