Problems solved by technology

The real stone paints currently used are all liquid synthetic resin emulsion real stone paints. The film-forming aids and other additives in the formula generally use organic solvents. Organic solvents are volatile and will pollute the environment and endanger human health.
And the existing macromolecular emulsion, anti-ultraviolet ability is poor, and weather resistance is poor, and it is easy to crack, easy to fade, easy to bloom after being irradiated by ultraviolet light.
In addition, it is often due to the difference in thermal expansion and contraction, which leads to cracking and falling off of the real stone paint surface or paint surface.
At the same time, the existing real stone paint for exterior walls does not have radiation protection and pollution resistance.

[0027] A1: Octaphenyl cage polysilsesquioxane modified sulfonated polyimide, prepared by the following method:

[0028] In a 100mL dry three-neck flask, add 1.6mmol 2,2'-bis(4-sulfophenoxy)biphenyldiamine, 12.5mL m-creso1 and 0.8mL triethylamine successively, and protect with nitrogen gas and Magnetic stirring; after 2,2'-bis(4-sulfonic acid phenoxy)biphenyldiamine is completely dissolved, then add 1.55mmol 3,4,9,10-perylenetetracarboxylic anhydride, 3.0mmol benzoic acid And 0.6mL isoquinoline; after stirring at room temperature for 1h, raise the temperature to 80°C for 4h, 180°C for 20h; After that, the polymer was collected by suction filtration, and dried in a vacuum oven at 60°C for 20 hours to obtain an amino-terminated sulfonated polyimide prepolymer;

[0029] 100 grams of the amino-terminated sulfonated polyimide prepolymer are first dissolved in 1000 grams of polyphosphoric acid containing 86 wt% phosphorus pentoxide, and then the amino-terminated sulfonated polyimide...

Embodiment 1

[0045] In parts by weight, add 35 parts of A1, 100 parts of B1, 6 parts of C1, 4 parts of D1, 3 parts of E1, 2 parts of F1 and 5 parts of G1 into the mixer and mix them thoroughly for 10 minutes to obtain a radiation-proof exterior wall. Real stone paint. According to the weight ratio, the real stone paint and water are mixed at a ratio of 1:0.5, and the above mixture is stirred with an electric mixer for 10 minutes. After being fully mixed, it is coated on the outer wall to complete the construction.

Embodiment 2

[0047] In parts by weight, add 35 parts of A2, 100 parts of B1, 6 parts of C1, 4 parts of D1, 3 parts of E1, 2 parts of F1 and 5 parts of G1 into the mixer and mix them thoroughly for 10 minutes to obtain a radiation-proof exterior wall. Real stone paint. According to the weight ratio, the real stone paint and water are mixed at a ratio of 1:0.5, and the above mixture is stirred with an electric mixer for 10 minutes. After being fully mixed, it is coated on the outer wall to complete the construction.

Abstract

The invention discloses anti-radiation outer wall real stone paint. The anti-radiation outer wall real stone paint is prepared from, by weight, octa-phenyl cage type polysilsesquioxane modified sulfonated polyimide, natural colored sand, a water-retaining agent, an antifoaming agent, lignocellulose, an antifreezing agent and KH-560. The invention further discloses a preparation method and a construction method of the anti-radiation outer wall real stone paint.

Description

technical field [0001] The invention belongs to the technical field of real stone paint, in particular to a real stone paint for anti-radiation exterior walls. Background technique [0002] Real stone paint for exterior walls is widely used in people's lives. The real stone paints currently used are all liquid synthetic resin emulsion real stone paints. The film-forming aids and other additives in the formula generally use organic solvents. Organic solvents are volatile and will pollute the environment and endanger human health. Moreover, the existing polymer emulsion has poor ultraviolet resistance and poor weather resistance, and it is easy to crack, fade and bloom after being irradiated by ultraviolet rays. In addition, the thermal expansion and contraction are often different, resulting in cracking and falling off of the real stone paint surface or paint surface. At the same time, the existing real stone paint for exterior walls does not possess radiation protection an...
