Description
Technical Field
The invention relates to the field of coating materials, in particular to an emulsifier for a low-solid-content water-based epoxy resin coating and a preparation method thereof.
Background
With the successive release of national environmental protection policies and the stricter of legal regulations, coating enterprises invest a lot of manpower and material resources to develop environment-friendly low-VOC coatings including epoxy coatings.
There are many technical routes for environmental protection epoxy coatings, such as water-borne epoxy coatings, solvent-borne high solids coatings, solventless, powder, and the like. The different kinds of coatings have respective unique performance and characteristics, and can meet the application requirements of different occasions. The solvent-free and powder coating technical route can almost realize zero VOC, although the requirement on construction environmental conditions is high, the technology is relatively mature, so that the solvent-free and powder coating technical route needs not the innovation of the technology but the innovation and the popularization of application. Therefore, the VOC-containing solvent-based epoxy coating is a key target for VOC emission reduction of future coatings.
Epoxy coatings have three possible directions to reduce VOC:
1) high VOC, low solids solvent-borne coatings (VOC >420g/L) are turning to low VOC, low solids waterborne coatings (VOC <420g/L), a direction that is in the category of "oil to water".
2) The direction in which high VOC, low solids solvent-borne coatings (VOC >420g/L) are turned to low VOC, high solids solvent-borne coatings (VOC <420g/L) is in the category of "oil to oil".
3) The low VOC high solids solvent borne (VOC <420g/L) is moving to ultra low VOC high solids aqueous coatings in the "oil to water" category.
However, the epoxy resin emulsifier used in the water-based paint has more problems, which are mainly reflected in that:
1) the emulsion process is very complex, different equipment, although determining the approximate process, different product types require completely different processes.
2) The time of emulsification is long. Regardless of the other production process times, emulsification of weatherable epoxy requires 7-8 hours, or even longer.
