Chips of glass product has coloured coating and manufactures this color coating method

摘要

The color coating of the invention, so that the surface of some or all small glass articles is transparent, and by two layers (2,3), it is by synthesizing clear varnish from the surface of base (2) towards glass, preferred epoxy or acryl urethane or polyurethane lacquer, and top layer (3) is coloured and transparent, the manufactured dye base anthraquinone amino acid derivative in preferred embodiment. It is not have simili reflecting layer (5), or be related to those of a part of watch crystal bits product and to be used to apply simili reflecting layer (5) simili that color coating, which can be only applied to surface such segment glass bits product,. Cleaned during the preparation of above-described color coating method and dry watch crystal bits product immerse the mixture of the composition that the first epoxy resin or polyurethane or acryl urethane define, by mixture be applied to article surface by the effect of heat and it is dry after one coloring mixture of epoxy resin varnish that is formed be applied to clear, colorless ground glaze layer (2) obtained and obtain Transparent color top layer (3). Preferably, parison submerges and therefrom base mixture moves in vertical direction. Water dye bath includes 0.0001 to 1.Chips of glass product occurs for the dyestuff anthraquinone amino acid derivative of 6 parts by weight, water based on every 100 parts by weight and movement bath to be maintained at 10 to 140 degC degC periodic regimes from 10 second to 1 hour in constant bath temperature. Previous is immersed in dye bath, and parison can preheat thoroughly in advance. In the parison of movement dye bath, at normal temperature, bath is effectively stirred.
