Abstract
The invention relates to a coating material with the refractive index approximate to that of a mirror. The coating material comprises methacrylic acyloxy propyl trialkyl silane, sulfydryl propyl trialkyl silane, zirconium oxide wrapped by antimony oxide and integrally combined with titanium oxide, compound metal particles manufactured from silicon oxide and magnesium oxide, dicyandiamide, organic carboxylic acid and a cobalt (II) compound. The refractive index of the coating material is approximate to that of a base body, and the coating material has the anti-aging property.
Description
Technical field
The invention belongs to surfacing field, specifically refer to a kind of coating material for eyeglass, the refractive index of its refractive index and lens materials is approximate.
Background technology
Vision correction or sunglasses glass lens, owing to adopting high-index material to become thinner, one of them problem producing while forming coating on the lens of being made by this high-index material is the interference pattern being caused by the refractive index difference between this coating and lens.This interference pattern has caused the open defect of lens.
By making the refractive index of hard conating approach the refractive index of the lens that uses high-index material, developed the technology that can realize high index of refraction hard conating.By add the inorganic oxide particle of mainly being made by titanium dioxide in hard conating liquid, the refractive index of the hard conating of formation is improved.Although titanium dioxide contributes to improve the refractive index of hard conating, to compare with the hard conating that does not conform to titanium dioxide, for example ageing-resistant performance is poor for above-mentioned other physical property containing titanium dioxide hard conating.
Summary of the invention
The coating composition that the object of this invention is to provide a kind of ageing-resistant high refractive index coating.
The present invention is achieved by the following technical solutions:
A coating material approximate with eyeglass refractive index, composite metal particulate, dicyandiamide, organic polycarboxylic acid and cobalt (II) compound that zirconia, monox and the magnesium oxide of being combined with titanium dioxide one that include methacryloxypropyl trialkyl silane and sulfydryl propyl group trialkyl silane, is coated by antimony oxide is made.
The weight ratio of described methacryloxypropyl trialkyl silane and sulfydryl propyl group trialkyl silane is 2:1.
The mean grain size of the composite metal particulate that described zirconia, monox and the magnesium oxide of being combined with titanium dioxide one that be coated by antimony oxide is made is 8-12nm.
The thickness of described antimony oxide is the 150/1-1/100 of composite metal diameter of particle.
The weight ratio of the amount of solid of the composite metal particulate that described methacryloxypropyl trialkyl silane and sulfydryl propyl group trialkyl silane are made with zirconia, monox and the magnesium oxide of being combined with titanium dioxide one that are coated by antimony oxide is 1:1.
The weight ratio of described dicyandiamide and organic polycarboxylic acid is 1:1.
10% of the composite metal particulate loading that the weight of described dicyandiamide accounts for methacryloxypropyl trialkyl silane and sulfydryl propyl group trialkyl silane and zirconia, monox and the magnesium oxide of being combined with titanium dioxide one that are coated by antimony oxide are made.
Described organic polycarboxylic acid is itaconic acid.
The weight of described cobalt (II) compound be all the other components and 0.5%-1%.
Described cobalt (II) compound is the sequestrant with aliphatics ligand.
The invention has the beneficial effects as follows:
The coating obtaining by the technical program is similar to the refractive index of plastic basic unit, and ageing-resistant, and coating is thin, saves production cost.
