Description
Technical Field
The invention relates to the technical field of paint production, in particular to a heat-insulating paint for water-based color steel tiles and a preparation method thereof.
Background
The color steel tile is also called color profiling tile, which is a profiled plate made of color coated steel plate by rolling and cold bending into various wave patterns. The decorative material is mainly suitable for the decoration of roofs, walls, inner walls and the like of industrial and civil buildings, warehouses, special buildings and large-span steel structure houses, has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire resistance, rain resistance, long service life, no maintenance and the like, and has been widely popularized and applied. When the color steel tile is installed, the middle part of the tile is stepped on as much as possible, the edge of the tile is prevented from being stepped on, and the color steel tile is carefully installed in severe weather.
In daily life, a layer of paint is often required to be sprayed on the surface of the color steel tile, and the purpose of the paint is to protect the color steel tile to a certain extent, so that the color steel tile is prevented from being corroded due to long-time wind and sun exposure. The service life of the water heater is prolonged to a certain extent. However, although the coating on the market can play a certain role in protecting the color steel tile, the function of the coating is relatively single, such as the heat insulation performance of the coating is relatively insufficient, the ultraviolet resistance of the coating is relatively poor, the paint film of the coating can be aged to different degrees after being exposed to sunlight for a long time, and the service life of the coating is shortened to a certain extent. Based on the above, the invention provides a heat-insulating coating for water-based color steel tiles and a preparation method thereof, so as to solve the technical problem.
Disclosure of Invention
The invention aims to provide the heat-insulating paint for the water-based color steel tile and the preparation method thereof, and the prepared heat-insulating paint for the water-based color steel tile has good ageing resistance, good heat-insulating property, good protection effect on the color steel tile and prolonged service life to a certain extent.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the heat-insulating coating for the water-based color steel tile comprises the following components in parts by weight: 35 to 45 parts of acrylic emulsion, 45 to 60 parts of polyurethane emulsion, 0.2 to 0.35 part of polydimethylsiloxane, 0.12 to 0.2 part of fluorosilicone, 1.6 to 2.3 parts of sodium hexametaphosphate, 2 to 4.5 parts of propylene glycol methyl ether acetate, 2.5 to 3.8 parts of nano silicon dioxide, 1.8 to 2.5 parts of nano zinc oxide, 2.0 to 3.5 parts of sericite, 1.5 to 2.5 parts of precipitated barium sulfate, 8 to 15 parts of functional additive, 0.7 to 1.2 parts of pigment, 0.5 to 0.8 part of thickener, 0.3 to 0.7 part of preservative, 0.3 to 0.6 part of ultraviolet absorber and 10 to 30 parts of deionized water.
Further, the preparation method of the functional additive comprises the following steps:
