Super-scratch-resistant unsaturated polyester matte transparent finish paint

Abstract

The invention discloses the field of decoration and coating of wooden office furniture and particularly relates to a super-scratch-resistant unsaturated polyester matte transparent finish paint which can meet the curing of a normal-temperature environment condition and can finish through spraying construction; and a coating film has an excellent wear resistance. The super-scratch-resistant unsaturated polyester matte transparent finish paint is formed by mixing a main paint, an initiator and an accelerant; and the weight proportion is that the main paint to the initiator to the accelerant is 100: 1.6: 1.8. According to the super-scratch-resistant unsaturated polyester matte transparent finish paint disclosed by the invention, the scratch-resistant problem of a UPE unsaturated polyester wood transparent matte coating is completely solved; the finish paint is treated by a certain construction process and then can be directly sprayed on the surface of wooden furniture; the scratch resistance is excellent, and the flexibility and the fullness are good; and finish paint can be used for coating protection on the surface of the wooden furniture, has a good mechanical performance and is simple to operate; and an environment-friendly and excellent-performance air-drying transparent matte coating is provided.

Description

technical field [0001] The invention discloses the field of decorative coating for wooden office furniture, and in particular relates to a super scratch-resistant unsaturated polyester matte transparent which can be cured under normal temperature and environmental conditions and completed by spraying. The coating film has excellent wear resistance. top coat. Background technique [0002] At present, the development of unsaturated polyester furniture paint is very rapid, especially in the wooden office furniture decorative coating market, there is only unsaturated polyester bright transparent topcoat, and the scratch resistance is average; there is no one for wooden office furniture Supply of matt unsaturated polyester clear topcoat and super scratch resistant unsaturated polyester matt clear topcoat.

Problems solved by technology

[0003] In order to pursue a matte effect, people often use a two-component PU polyester transparent matte finish, especially a transparent matte finish for wooden office furniture. The first component of the finish contains an isocyanate curing agent. For alkyd resins containing hydroxyl components in component B, since component A contains isocyanate, some free TDI will still exist after the paint film dries, which will easily cause great harm to people. At the same time, if an excessive amount of curing agent is added, although the hardness can It is similar to the paint film of unsaturated polyester, but the flexibility is not good, it is easy to be scratched, and it cannot meet the requirements of users
