Abstract
The invention relates to an epoxy resin powder paint and application thereof. The paint contains the following components in parts by weight: 20-40 parts of E-12 epoxy resin, 20-40 parts of polyester resin, 6-25 parts of organic silicon resin and 2-15 parts of pigment. The paint can be obtained through normal powder paint preparation methods. The epoxy resin powder paint has excellent weather fastness, and the film formed after the paint is coated is well-rounded and glossy and has good luster and excellent adhesion. Therefore, the epoxy resin powder paint can be used in coatings of middle and top grade household appliances.
Description
Technical field
The present invention relates to a kind of coating, be specifically related to a kind of epoxy powder coating and application thereof.
Background technology
Epoxy powder coating is a kind of dry state pressed powder that does not contain organic solvent; It is different with the coating and the water-borne coatings of common solvent type; Need be during application with solvent or water as dispersion medium, but with air as dispersion medium, be coated on workpiece surface equably; Heating back forms a kind of new coating of filming, and this is the remarkable difference part with other coating.
Epoxy powder coating and application techniques are the new development on paint spraying again behind water-soluble electrophoretic paint, and it is to meet economy, ecology, the energy, a novel material of effect four principles, novel process, new technology.The sixties, the powder coating coating technology development of external advanced country was swift and violent, had much the gesture that replaces solvent reducible coatings.The current powder coating of producing generally adopts extrusion process, makes epoxy powder begin to go on industriallization.The seventies, the powder coating development of China was rapid; Almost increase with 80 ~ 100% speed every year; Powder coating of current China and powder electrostatic coating equipment have got into promotes developmental stage at a high speed; Powder coating is one of coating of giving priority to of China's " the Seventh Five-Year Plan ", progressively to replace traditional solvent-borne type paint.
CN101885831A discloses a kind of preparation method who is used for the polyester modified epoxy resin of household electroplate primer; It is through vulcabond vibrin to be grafted on the epoxy resin; The method of with hydramine the part epoxy group(ing) being carried out open loop again prepares polyester modified epoxy resin; Used vibrin is the terminal hydroxy group linear polyester resin, and used epoxy resin is the bisphenol A type epoxy resin that has two secondary hydroxyls at least.The inventive method makes the gained polyester modified epoxy resin contain ammonia ester bond, ester bond, primary hydroxyl, secondary hydroxyl and epoxy group(ing) simultaneously; Therefore; Merge the advantage of existing vibrin and epoxy resin, abandoned their shortcoming simultaneously, possessed excellent flexibility, sticking power and antiseptic property; Household electroplate primer by its preparation is compared with the polyester primer performance with traditional epoxy primer, and over-all properties is more excellent.
