Problems solved by technology

[0003] At present, water-based glass coatings have gradually begun to be water-based, and there are many products on the market that can meet the general physical property requirements. However, the water-based glass coatings in the prior art have the defect of poor resistance to boiling at 100°C, which cannot meet the requirements of high-end customers. Therefore, it is of great significance to develop a water-based glass protective coating resistant to boiling.

Abstract

The invention relates to the technical field of coatings, and particularly relates to a water-boiling-resistant high-temperature-baking-resistant glass protective coating and a preparation method thereof. The water-boiling-resistant high-temperature-baking-resistant glass protective coating is prepared from water-based acrylic resin, water-based amino resin I, water-based amino resin II, water-based epoxy resin, a wetting flatting agent, an amine neutralizer, a water silane coupling agent, a coalescing agent, a thickening agent and water. The water-based acrylic resin used in the formula is especially suitable for glass substrates and is good in water resistance, so that the requirement of adherence of most glass materials and the requirement of one-hour water boiling resistance at 100 DEGC of can be met. In addition, the water-based silane coupling agent used in the formula has strong adhesion to a glass substrate, and can meet the requirement of adhesion of some special glass materials and the performance requirement of one-hour water boiling resistance at 100 DEG C. The preparation method of the boiling-resistant high-temperature-baking-resistant glass protective coating has the characteristics of simple process, low production cost and suitability for large-scale production.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a boiling-resistant high-temperature baking glass protective coating and a preparation method thereof. Background technique [0002] With the application of glass products more and more widely, glass protective coatings can play a good role in protecting glass and impart specific properties, so the preparation of glass protective coatings is becoming more and more important. [0003] At present, water-based glass coatings have gradually begun to be water-based, and there are many products on the market that can meet the general physical property requirements. However, the water-based glass coatings in the prior art have the defect of poor resistance to boiling at 100°C, which cannot meet the requirements of high-end customers. Therefore, it is of great significance to develop a water-based glass protective coating that can withstand boiling. Contents of the invention [0004]...
