In view of this, be necessary to provide a kind of can according to the method for making of the reflectance coating of the accurate location and installation of pre-provisioning request and this reflectance coating.
A kind of reflectance coating, can be used for spreading upon on the smooth reflecting surface of metal substrate, described reflectance coating is the composition of hardening agent and reflective powder, and wherein said hardening agent comprises acryl series monomers, polyurethane acryl oligomer, polyester acryl modification polyester oligomer and light initiator.
A method for making for reflectance coating, comprises the steps:
S1: hardening agent and reflective powder are mixed to form composition, described hardening agent is acryl series monomers, polyurethane acryl oligomer, polyester acryl modify polyester oligomer and light initiator is mixed to form composition;
S2 a: metal substrate is provided, and by the composition uniform application that is mixed to form by hardening agent and reflective powder to the surface of metal substrate;
S3: adopt this composition smearing to metallic substrate surfaces of ultraviolet source irradiation to make it the reflectance coating being formed and be attached to metallic substrate surfaces that hardens.
Reflectance coating of the present invention is mixed to form by reflective powder and the composition modifying polyester oligomer and light initiator containing acryl series monomers, polyurethane acryl oligomer, polyester acryl, and it can be formed on the surperficial preposition of metal substrate according to predetermined requirement in the mode of smearing.
Accompanying drawing explanation
Fig. 1 is the diagrammatic cross-section of metal substrate of the present invention and reflectance coating.
Main element symbol description
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the mode that reflectance coating 20 of the present invention can be smeared is formed on the reflecting surface of metal substrate 10.
Described metal substrate 10 is a smooth metal plate, and it can be made up of the metal material that the reflectivity such as copper, aluminium is good.Described metal substrate 10 comprises a smooth and smooth upper surface 101 and parallel with this upper surface 101 and spaced smooth a lower surface 102.In the present embodiment, described upper surface 101 is the reflecting surface of described metal substrate 10.
