Problems solved by technology

[0004] Due to the existing preparation process of nuclear-type nano-powder materials, the process route of preparing nano-nuclei particles first and then coating them is basically adopted, and then undergoes crystallization heat treatment in the later stage, but the process flow is complicated and the production cycle is long. The cost is high, and the realization of industrialization has limitations

Abstract

The invention discloses a core-shell organic silicon durable paint and a preparation method thereof. The preparation method comprises the steps of: adding water, cellulose and the like in a sealed pressure container to prepare a core by a hydrothermal method at 50-70 DEG C in a mixing manner; reacting for less than 30min; then, adding a dispersant DP270, a bactericide XG-405, a paint defoamer NXZ and the like by weight percent continuously at the same time for polymerization; uniformly agitating, curing, and correcting the viscosity; and metering and packaging after inspection by technical indexes. The core-shell organic silicon durable paint provided by the invention has the beneficial effects that the manufacturing process is simple and the manufacturing cost is low, so that the core-shell organic silicon durable paint is suitable for industrialization and is the optimal representative of new generation of water-based paints. The core-shell organic silicon durable paint integrates the environment protection performance of the water-based paint and the light-maintaining, color-maintaining, super-weatherproof and super-stain preventing performances of the oil paint. The film has good acid-resisting, alkali-resisting and chemical pollution-resisting performances and the like, so that the core-shell organic silicon durable paint is suitable for new projects and projects of large buildings such as various houses, office buildings, hotels, plants and schools.

Description

technical field [0001] The invention relates to a core-shell type organosilicon durable coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] The method of changing the properties of the powder by coating the surface of the Nazi powder is an important method in the surface coating modification method, and the shell layer can be either organic or inorganic. According to needs, making it compatible with materials or improving its thermomechanical and chemical stability, changing optical, magnetic, electrical properties and service life, and controlling the surface chemical composition of nanopowders are the keys to increasing the added value of nanopowders. [0003] The core-shell polymer is a polymer composite particle with a unique structure, which has better stability, adhesion and mechanical properties than the usual emulsion blends or random copolymers, so it is used in adhesives, anti-corrosion It has a wid...
