Waterborne nano coil coating and preparation method thereof

Abstract

The invention belongs to a waterborne nano coil coating and a preparation method thereof. Firstly, an inorganic material with no toxic property, foreign smell and combustion characteristic is used as a basic powder material of a coil coating, a waterborne acrylic emulsion, waterborne epoxy resin, water-soluble functional auxiliaries and other film forming matters are compounded, updated and modified by using a nanotechnology and nano materials, and gaps of large micro materials in a coating structure are filled by using various nano powder materials after the hydration of the coil coating is effectively finished, so that the coating generates a coating function enhancing effect under the synergistic action of multi-effect combination of the nano materials and micro materials, the defect that the performance of the waterborne coil coating prepared by a micrometer technology is lowered is overcome effectively, and the technical performance of the waterborne coil coating is remarkably enhanced. By using the waterborne nano coil coating and the preparation method thereof, the production efficiency is increased, the fire risks and industrial pollution of the traditional solvent type coil coating are eliminated, and meanwhile, the aim of safe, environment-friendly, low-consumption and efficient production is achieved.

Description

technical field [0001] The invention belongs to a water-based nano-coil coating and a preparation technology thereof, and relates to modifying and upgrading traditional coil coating materials and chemical substances by using nanotechnology and nano-materials to prepare a water-based nano-coil coating.

Problems solved by technology

The coating process of this traditional solvent-based coil coating causes high energy consumption, waste of resources and high pollution discharge, which seriously restricts the development of coil coating and coating industry in China.

[0006] At present, there are more than 200 coil coating production enterprises in China, nearly 400 coating production lines, and the total annual designed production is about 10 million tons. Due to factors such as pollution and technology of traditional solvent-based coil coatings and coating processes, The total annual production of coils is less than 3.3 million tons, which is only 1 / 3 of the total annual design and production of coil coating production lines in my country. For a long time, the entire industry has been in a state of single products, low quality, repeated production and disorderly competition in the market

It can be seen that traditional solvent-based coil coatings and coating processes are difficult to achieve industrial safety, environmental protection, low-carbon energy saving and product upgrades; while traditional micron-level technology for research on water-based coil coatings and coatings is very difficult. It is difficult to break through the key technical threshold of water-based coil coatings and coatings
