Abstract
Invention is related to chemical composition technical field, is related to a kind of coating for surface, refers in particular to a kind of polyurethane paint.It is made of polyurethane resin, dimethylbenzene, butyl acetate, cyclohexanone, cyano-acetoxy class compound.The advantages of invention, is：Following situations can be avoided, object plane is bad, has greasy dirt substance, bottom cleaning is not clean, and adhesive force is bad after conjunctiva；Object plane is excessively smooth, and paint film is too thin after brushing, and adhesive force is bad, generates cracking decortication phenomenon.
Description
Technical field
Invention is related to chemical composition technical field, is related to a kind of coating for surface, refers in particular to a kind of polyurethane paint.
Background technology
Polyurethane paint, that is, polyurethanes paint.Its paint film is tough, and gloss is plentiful, strong adhesive force, water proof and wearable, corrosion-resistant
Property.It is widely used in high-class woodenware furniture, it can also be used to metal surface.The characteristics of Polyester Paint is can shape between high-polymer molecular
At acyclic and/or annular hydrogen bond, under external force, hydrogen bond it is separable and absorb external energy (per molar absorbance 20~
25kJ).Hydrogen bond can be re-formed again again after external force removes.The reversible repetition that hydrogen bond so splits, and re-forms, makes poly- ammonia
Ester paint film has high degree of mechanical wearability and toughness.Compared with other paint, under the conditions of same rigidity, due to the work of hydrogen bond
With the elongation at break highest of Polyurethane lacquer, so being widely used as floor paint, overtime work paint, high-decoration anti-decaying paint etc..Coating
In some kind (such as epoxy, chlorinated rubber) defencive functions it is good and decorative slightly worse；It is filled if some kinds (such as nitrate paint etc.)
Decorations property is good and defencive function is poor.However polyurethane paint has both protection and dicoration, can be used for high-class woodenware, piano, airliner
Deng application.Although it has more feature, its disadvantage mainly has blisters in case of wet, film efflorescence, in object surface light
In the case of cunning, adhesive force is bad, influence it is bad, cause be easy cracking.
Invention content
The purpose of invention is in view of the above-mentioned problems, providing a kind of strong adhesive force so that the poly- ammonia that product is not easily susceptible to cracking
Ester paint.
In order to achieve the above objectives, invention uses following technical proposal：Polyurethane paint, which is characterized in that by polyurethane tree
Fat, dimethylbenzene, butyl acetate, cyclohexanone, cyano-acetoxy class compound composition；The cyano-acetoxy class compound
Basic structural formula be
In a kind of above-mentioned polyurethane paint, the polyurethane resin is 180 parts -220 parts, dimethylbenzene is 18 part -22
Part, butyl acetate are 13 parts -19 parts, cyclohexanone is 3 parts -9 parts, cyano-acetoxy class is 55 parts -68 parts.
In a kind of above-mentioned polyurethane paint, the cyano-acetoxy class compound is 6- (2- cyanoethyls) -17 α -
Acetoxyl group corpus luteum ketone compounds.
Compared with prior art, it is the advantages of invention：Following situations can be avoided, object plane is bad, there is greasy dirt class object
Matter, bottom cleaning is not clean, and adhesive force is bad after conjunctiva；Object plane is excessively smooth, and paint film is too thin after brushing, and adhesive force is bad, production
Raw cracking decortication phenomenon；Coating quality is bad, and resin, gum components are too many in coating, easy embrittlement after film forming.
