Description
Technical Field
The invention relates to the technical field of chemical coatings, and particularly relates to a water-based shop primer with excellent initial water resistance and a preparation method thereof.
Background
The shop primer, namely the steel pretreatment primer, is a quick-drying primer which is sprayed on the surface of steel after the steel (steel plate or profile steel) is subjected to sand blasting treatment and rust removal on a coating production line, plays a role in rust prevention on the steel in the processes of storage, processing and assembly, and reduces the workload of secondary rust removal. It is subject to significant varieties of polyvinyl butyral shop Primer (PVB), epoxy zinc rich shop primer, epoxy iron red shop primer, inorganic zinc silicate shop primer, and the like. With the increasing awareness of environmental protection, the development of water-based anticorrosive coatings has been on the rise, and water-based shop primers are also listed as one of the main varieties of water-based coatings. The VOC content of the solvent type workshop primer is as high as 600-680 g/L, and the water-based workshop primer can realize almost zero VOC, so that the VOC emission is greatly reduced.
The water-based shop primer is developed based on an inorganic silicate technology, the film forming speed of the water-based alkali metal silicate depends on the modulus of the silicate, the modulus is low, the film forming speed is slow, the initial water resistance is poor, the alkali metal silicate contains a large amount of alkali metal cations, the ions still exist in the coating after drying, the water absorption is strong, and the reason for the poor initial water resistance is also high. High modulus improves water resistance, but has the problems of poor stability and poor adhesion. Therefore, although the film formation mechanism of the water-based shop primer is different from that of the organic water-based anticorrosive paint, there is a problem of initial water resistance similar thereto. The steel plate just coated with the shop primer is quickly stored outdoors, and if the steel plate meets rainy days, the protection effect is influenced by the poor water resistance of the initial paint film.
