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 of strong adhesive force.It is made of polyurethane resin, dimethylbenzene, butyl acetate, cyclohexanone, acetoacetate 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 strong adhesive force
Polyurethane paint.
Background technology
The polyurethane paint of strong adhesive force, that is, polyurethanes paint.Its paint film is tough, and gloss is plentiful, and strong adhesive force is water-fast
Wear-resisting, corrosion resistance.It is widely used in high-class woodenware furniture, it can also be used to metal surface.The characteristics of Polyester Paint is in high polymer
Acyclic and/or annular hydrogen bond can be formed between molecule, under external force, hydrogen bond is separable and absorbs external energy (often
20~25kJ of molar absorbance).Hydrogen bond can be re-formed again again after external force removes.Hydrogen bond so splits, but re-form can
It is inverse to repeat, make the Polyurethane lacquer of strong adhesive force that there is high degree of mechanical wearability and toughness.Compared with other paint, identical hard
Under the conditions of degree, due to the effect of hydrogen bond, the elongation at break highest of the Polyurethane lacquer of strong adhesive force, so being widely used as floor
Paint, overtime work paint, high-decoration anti-decaying paint etc..Defencive function is good and decorates for some kinds (such as epoxy, chlorinated rubber) in coating
Property is slightly worse；Good decorative property if some kinds (such as nitrate paint etc.) and defencive function is poor.However the polyurethane paint of strong adhesive force has both
Protection and dicoration, can be used for the application of high-class woodenware, piano, airliner etc..Although it has more feature, its
Disadvantage mainly has blisters in case of wet, and film efflorescence, in the case where object surface is smooth, adhesive force is bad, influences bad, causes to hold
It is easy to crack.
Invention content
The purpose of invention is in view of the above-mentioned problems, providing a kind of strong adhesive force so that the attachment that product is not easily susceptible to cracking
The strong polyurethane paint of power.
In order to achieve the above objectives, invention uses following technical proposal：The polyurethane paint of strong adhesive force, which is characterized in that
It is made of polyurethane resin, dimethylbenzene, butyl acetate, cyclohexanone, acetoacetate class compound；The acetoacetate class chemical combination
The basic structural formula of object isR5 and R6 is alkyl or cycloalkyl；R7 is hydrogen or methyl.
In a kind of polyurethane paint of above-mentioned strong adhesive force, the polyurethane resin is 180 parts -220 parts, dimethylbenzene
For 18 parts -22 parts, butyl acetate be 13 parts -19 parts, cyclohexanone is 3 parts -9 parts, acetoacetate class is 55 parts -68 parts.
In a kind of polyurethane paint of above-mentioned strong adhesive force, the acetoacetate class compound is acetoacetic ester.
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.
