Environment-friendly anti-scaling nano-ceramic membrane coating and preparation method of the environment-friendly anti-scaling nano-ceramic membrane coating

Abstract

The invention provides an environment-friendly anti-scaling nano-ceramic membrane coating and a preparation method of the environment-friendly anti-scaling nano-ceramic membrane coating, belonging to the field of functional coating. The formula of the environment-friendly anti-scaling nano-ceramic membrane coating contains the ingredients as follows: 15-65% of aluminum sol, 15-65% of silica sol, 4-20% of silane monomers, 3-27% of pigments, 3-27% of fillers and 5-25% of anti-settling agent. The preparation method includes the step as follows: respectively weighing aluminum sol, silane monomers, pigments, fillers and anti-settling agent in corresponding weight, and then conducting mixing, high-speed dispersion and grinding, wherein the ground mixture serves as component a; weighting silica sol in corresponding weight, wherein the silica sol serves as component b; and mixing the component a with the component b, and sanding and curing the mixture, thus obtaining the -ceramic membrane coating. On the basis of inorganic membrane forming materials, the hydrophobic characteristic of the coating is regulated by changing the types and the ratio of the silane monomers, so that the environment-friendly anti-scaling nano-ceramic membrane coating achieves good bonding property with a transport device and also can effectively prevent scaling or biological rooting; and simultaneously the nano-ceramic membrane coating has the quality of a enamel surface, excellent decoration, safety and innocuity, thus being an environment-friendly coating.

Description

technical field

[0001] The invention belongs to the field of functional coatings, and relates to an environment-friendly anti-scaling nano-ceramic film coating and a preparation method thereof. Background technique

[0002] Various transportation and heating pipelines or large-scale heating devices often reduce their working efficiency due to fouling in applications. For example, after the heating pipe is scaled, it will seriously corrode the pipe wall and reduce the heating efficiency. On the one hand, due to the hard water containing some minerals in the water pipeline, scale will be formed on the inner wall of the pipeline during transportation; on the other hand, the pipeline that transports biologically-rich sewage is often attacked and polluted by sessile organisms during application. In this way, the efficiency of transportation is greatly reduced, and the cost of replacing the transportation device or dredging the pipeline is increased. In particular, the fouling p...
