Embodiment 1

[0022] The formula ratio of this solvent-based super weather-resistant exterior wall paint is:

[0023]

[0024] Its preparation method is:

[0025] A, thermoplastic acrylic resin is dropped in the reactor;

[0026] B. Start the mixer and add a part of diluent, dispersant, and wetting agent to the reaction kettle in sequence at a stirring speed of 200-500 rpm for stirring, and stir for more than 10 minutes until the materials are evenly mixed to obtain a mixture;

[0027] C. Add colored pigments and fillers to the mixture obtained in step B successively at a stirring speed of 200-500 rpm, and then stir at a speed of 1000-1200 rpm for more than 15 minutes;

[0028] D. After stirring evenly, grind with a horizontal sand mill, and stop when the fineness is below 50 microns;

[0029] E. After the fineness meets the requirements, continue to stir at a stirring speed of 200-500 rpm, and slowly add defoamer and stir until uniform;

[0030] F. Add the remaining diluent to adjust...

Abstract

The invention discloses solvent-type super-weather-proof exterior wall coating and a preparation method thereof, and relates to the technical field of chemical engineering. The solvent-type super-weather-proof exterior wall coating comprises the following components in percentage by weight: 55%-70% of thermoplastic acrylic resin, 10%-25% of coloring pigment, 10%-25% of filler, 0.1%-0.5% of defoaming agent,.1% -0.5% flatting agent, 0.1%-0.5% of wetting agent and 5%-10% of thinning agent. The solvent-type super-weather-proof exterior wall coating is a tough acrylic resin system, and a coating formed by the exterior wall coating has high durability in any climate, very good weather fastness, excellent waterproof performance and washing resistance and very good dirt resistance and self-cleaning ability and resists ultraviolet lights and corrosion of chemical substances in environments; a coating film formed by the exterior wall coating has good low-temperature drying performance, so that the construction can be carried out in cold reasons; the solvent-type super-weather-proof exterior wall coating has good adhesive force with multiple substrates and used coating films.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a solvent-based super-weather-resistant exterior wall paint and a preparation method thereof. Background technique [0002] Most of the paints sold on the market in our country are mostly low-grade latex paints, which have poor stain resistance, are easy to change color, and have a service life of only about three years. The low-temperature film-forming effect is poor, and it is not suitable for construction in winter. The performance indicators of some raw materials contained can neither meet the above requirements nor meet the environmental protection and safety requirements. the Contents of the invention [0003] The invention provides a solvent-based super-weather-resistant exterior wall paint and a preparation method thereof, which can solve the problems that the existing exterior wall paints have poor weather resistance, are easy to yellow and cannot be cons...
