Table 1
Comparative example 1 is with the difference of embodiment 1, the content mistake of polyvinyl butyral resin in composite paint system
It is low, it is 2.06%；Polyamide, epoxy resin content it is higher, respectively 30.9%, 5.15%, the levelling of comparative example 1 effect
Really, there is significantly decline compared with embodiment 1 in flatness, attachment fastness, anti-counterfeit recognition performance etc.；Comparative example 2 and embodiment 2
Difference is that the too high levels of polyvinyl butyral resin in composition system, are 18.4%, polyamide, asphalt mixtures modified by epoxy resin
The content of fat is relatively low, and respectively 9.22%, 7.37%, the levelling effect of comparative example 2, flatness, attachment fastness, anti-counterfeit recognition
Can wait, also occur being decreased obviously compared with embodiment 2, or even coating occur and adhere in nickel version；Comparative example 3 exists with the difference of embodiment 3
In the too high levels of composition system epoxy resin are 11.4%, and polyamide, polyvinyl butyral resin contain
Amount is relatively low, and respectively 15.5%, 11.4%, levelling effect, flatness, attachment fastness, anti-counterfeit recognition performance of comparative example 3 etc.,
Also occur being decreased obviously compared with embodiment 3, or even molding temperature occur narrow, it is difficult to the problem of regulation.Therefore, by embodiment 1,2,
3 and comparative example 1,2,3 comparison understand, key component-polyamide, epoxy resin and poly- second in present composition system
Enol butyral resin under certain proportion relation, the levelling effect, smooth that the compositionss of the present invention could be caused to have had
The radium-shine rainbow effect of degree, attachment fastness, anti-counterfeit recognition performance and protrusion.
Embodiment 2,4,5 and embodiment 1,3,6 are contrasted and is understood, polyamide is (1~3) from weight ratio:
The non-reacted polyamide of (1~2), the mixture of reactive polyamide resin, and epoxy resin is from weight ratio
1：(1~2):The glycidyl ether type epoxy resin of (1~3), glycidyl ester epoxy resin, (+)-2,3-Epoxy-1-propanol amine asphalt mixtures modified by epoxy resin
The mixture of fat, and polyvinyl butyral resin is (1~4) from weight ratio:The polyvinyl butyral resin tree of 1 middle viscosity
In the case of fat, low viscous polyvinyl butyral resin mixture, the composition system for enabling to the present invention possesses most
