Abstract

The invention discloses an alkyd resin paint, which comprises the following components by weight: 22-32 parts of C5-9 synthetic fatty acid, 30-35 parts of tung oil, 8-12 parts of rosin maleate, and pentaerythritol 14-18 parts, phthalic anhydride 11-15 parts, xylene 45-65 parts and turpentine 40-45 parts. The alkyd resin paint of the present invention has excellent adhesion, excellent impact resistance, surface hardness, toughness, adhesion and other mechanical properties, and can be used for steel bars, water pipes, valves, steel cylinders, agricultural machinery, automobile parts and building steel structures. Surface spraying. The invention is suitable for spraying by the method of high-voltage electrostatic spraying.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to an alkyd resin paint. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. In the prior art, its powder coating is composed of polyester resin, blocked isophor copper diisocyanate, benzoin and dibutyltin dilaurate. Its disadvantages are poor physical properties, poor covering effect, and easy generation of fine bubbles. Unable to meet electrical spraying and surface protection. That is, the existing powder coatings have poor coverage and cannot meet the needs of production and life. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies and provide...
