Description

Lacquer coating application technique
Technical field
The present invention relates to technical field of building construction more particularly to a kind of lacquer coating application techniques.
Background technique
It is also most commonly used material that coating, which is most important in decoration of exterior wall stone material, and solvent type especially therein applies Material, with the exploitation of China's real estate, economic fast development, the various performances of solvent based coating with technology maturation, Various indexs also have the development advanced by leaps and bounds, such as: water resistance, corrosion resistance, resistance to ag(e)ing.But solvent based coating exists The serious environment for having polluteed our lives of a large amount of organic volatile is had in use process, our health is also functioned to Serious threat.Society all advocates sustainable development now, so exploitation use environment close friend coating is particularly important.Institute The Environmentally friendly coatings of meaning, exactly to the environment-friendly health type that the health of human and animal is safe from harm, there are no pollution to the environment Coating, environmentally friendly, the coating not constituted a threat to the health of the mankind.From the point of view of being free of this angle of volatile organic matter, Environmentally friendly coatings mainly include four major class at present；Water paint, high solid powder coating, powdery paints and radiation curing apply Material etc..
Exterior coating is because its particularity will be influenced by outside environmental elements, the especially ageing-resistant performance of exterior coating Want relatively good with contaminated resistance.The ageing-resistant performance of coating is the embodiment of coating comprehensive performance, and superiority and inferiority directly influences it Service life and economy.The ageing-resistant performance for improving coating should comprehensively consider the factor for influencing paint aging performance, from former material Material, Design of Coatings Formulation and coating producing process etc. consider.Stain resistance and coating resistance to ag(e)ing are closely related, stain resistant The raising of property will also be set about from the design of the formula of coating.Guaranteeing the coating for making with excellent behavior pattern Under, then be controlled to construction link, color difference, the contamination sagging, floating occurred after could fundamentally overcoming coating to apply The problems such as.
Lacquer is since its is easy for construction, texture and decorative effect with lithotome, thus in external wall of high-rise building In external decoration engineering, the deep favor by numerous owners and builder.The present invention provides a kind of exterior insulation according to engineering practice Ture mineral varnish face brick-imitation effect decoration way, it would be desirable to the promotion and application of this construction technology are played and actively promote work With.
