It is one or more.
Preferably, described matrix resin is polymethyl methacrylate or polycarbonate.
Preferably, the resin curing agent be fats polyisocyanate or alicyclic ring class polyisocyanate, it is described organic molten
Agent is chloroform, methylene chloride or acetone.
A kind of preparation method of preventing ultraviolet night viewing compatible thin-film material, the specific steps of which are as follows:
(1) transparent substrate surface is cleaned up；
(2) each raw material for weighing preventing ultraviolet night viewing compatible coating in proportion, is dissolved in organic solvent, and it is simultaneous that UV resistance night vision is made
Hold coating, coating is coated in transparent substrate surface obtained by step (1)；
(3) by gained film drying 4 ~ 6 hours in step (2), it is small that 80 DEG C of curing ovens 5 ~ 8 are transferred to afterwards after the solvent is volatilized
When.
The utility model has the advantages that preventing ultraviolet night viewing compatible coating prepared by the present invention matches model by special technique and specifically
After enclosing preparation, obtained thin-film material has preferable transmitance in visible light region, and its uv resistance can be also very good, tool
There is very wide application prospect.
