Coating common sense: which coating base material is suitable for oxidative polymerization dry coating?

The key points are as follows: when the solvent or dispersing medium volatilizes, the coating material in the coating reacts with the oxygen in the atmosphere to solidify into a film, and the metal soap with organic acid is added to accelerate the drying process The metal soap of this kind of organic acid is called drier Long chain fatty acids (esters) increase the relative molecular weight by oxidation, so as to achieve oxidative polymerization and film-forming In the coating industry, grease is rarely used as the only film-forming material, and it is generally combined with other resins, such as terpene resin and phenolic resin to make oil resin paint or varnish Although alkyd resin manufacturing is not necessarily through Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Coating home news: when the solvent or dispersion medium volatilizes, the coating material in the coating reacts with the oxygen in the atmosphere to solidify into a film, and the metal soap with organic acid is added to accelerate the drying process The metal soap of this kind of organic acid is called drier Long chain fatty acids (esters) increase the relative molecular weight by oxidation, so as to achieve oxidative polymerization and film-forming In the coating industry, grease is rarely used as the only film-forming material, and it is generally combined with other resins, such as terpene resin and phenolic resin to make oil resin paint or varnish Although alkyd resin is not made by the reaction of vegetable oil and polyol, the mechanism of polymerization is the same Long oil alkyd resin, which is soluble in aliphatic hydrocarbon solvent, is widely used in air dry decorative coatings because of its good glossiness, light retention, weather resistance and easy to brush At the same time, the long oil alkyd resin can also be used as the main film-forming material in outdoor alkyd paint (steel structure paint, construction paint) In addition, alkyd resin can also be modified to form a new alkyd resin, mainly the adjustment of fatty acid type and oil degree, so that the comprehensive performance (drying speed, solubility, polymerization degree and compatibility with other resins) of the modified alkyd resin can be significantly improved Many air drying industrial coatings (such as those used for surface coating of heavy agricultural machinery) are made of styrene or vinyl toluene modified medium short oil alkyd resin as paint base with aromatic solvent The film was formed by oxidative polymerization and solvent evaporation If it is heated to 60-80 ° C, the drying speed can be obviously accelerated Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
