Description
Technical Field
The invention relates to the field of nano water-based paint, in particular to high-antifouling nano water-based paint, a preparation method and equipment.
Background
The nano antifouling paint in the prior art consists of a nano antifouling base material, a binder, a toxic agent, a pigment, an auxiliary agent and a solvent. The nano antifouling base material and the paint base are asphalt, chlorinated rubber, acrylic resin and vinyl resin. The original toxic agents were arsenic, mercury, and other compounds, which were banned due to their high toxicity. Currently, cuprous oxide, organotin compounds and their complexes are widely used. The auxiliary agent comprises a dispersing agent, an anti-settling agent, an exudation regulator and the like. The use of such antifouling paints has been totally banned by the international marine organization due to the toxicity of heavy metals and organotin. The adopted nano material has special properties such as surface effect, small-size effect, optical effect, quantum size effect, macroscopic quantum size effect and the like, and can enable the coating to obtain new functions.
The application of the nano material in the coating can be divided into two major categories, one category is the application in the oil coating and is called solvent type nano coating; the other is applied to water-based paint, called water-based nano paint, and the former has the advantages of chemical resistance, water resistance, good coating adhesion, wear resistance, good color retention and the like. But the most serious disadvantage is that the organic solvent or the toxic raw material is contained, and the environmental pollution and the human body damage can be caused in the production, construction and use processes. The latter has the advantages of no toxicity, no pollution, low cost and the like besides the advantages of the former, and the development and application of the water-based nano coating with environmental protection performance are undoubtedly the hot spots of research of people today with increasingly serious environmental problems.
The equipment arranged in the preparation process of the nano water-based paint is general equipment rather than special equipment, the preparation process, the components and the process cannot be completely matched, so that the production efficiency is low, the product quality is unstable, and particularly, the nano water-based paint cannot be continuously added in the stirring process. For example, chinese patent No. 201510777546.2 discloses a coating material dispenser, which includes: power, agitator motor, stirring support frame, puddler and stir the dish, agitator motor set up in stirring support frame, agitator motor with the power electricity is connected, the one end of puddler with agitator motor's output shaft, the other end of puddler with stir dish swing joint, this dispenser have simple structure, convenient to use's characteristics, and it adopts the puddler and stirs the dish cooperation and disperses, stirs coating. Because the stirring disc can move up and down relative to the stirring rod, the paint with different depths in the paint container can be stirred, so that a better stirring effect is achieved. The stirring of different degree of depth coatings is realized through adjusting the stirring dish, can reduce the repacking to the coating dispenser, reduces the cost of manufacture. But the processing of various processes such as stirring and feeding, heating, pressure reduction and the like can not be realized according to the components and the preparation process of the coating.
In conclusion, the existing nano water-based paint has some defects, cannot realize environmental protection, high-efficiency antifouling and poor antifouling effect of materials; meanwhile, the dispersing equipment for preparing the nano water-based paint can not be used for feeding materials while stirring, and various working procedures and processing methods can be integrated in one equipment to complete the process.
Therefore, a mutually matched high antifouling nano water-based paint, a preparation method and equipment are provided.
