Problems solved by technology

The film-forming aids and other additives in the currently used interior wall latex paint formulations generally use organic solvents, which are volatile and will pollute the environment and endanger human health
Moreover, the existing film-forming aids and other additives have poor UV resistance and poor weather resistance, and are prone to cracking, fading, and flowering after being irradiated by ultraviolet rays.
In addition, the phenomenon of cracking and falling off of the paint surface or paint surface is often caused by thermal expansion and cold contraction.
At the same time, the existing interior wall latex paint does not have radiation protection and stain resistance

preparation example Construction

[0031] G1: octaphenyl cage polysilsesquioxane modified sulfonated polyimide, prepared by the following method:

[0032] 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;

[0033] 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

[0044] In parts by weight, add 30 parts of A1, 2 parts of B1, 1 part of C1, 1 part of D1, 1 part of E1, 20 parts of F1, 35 parts of G1 and 8 parts of H1 into the mixer and mix them thoroughly for 10 minutes, and then discharge to obtain Anti-radiation interior wall latex paint. The radiation-proof interior wall latex paint is coated on the interior wall to complete the construction.

Abstract

The invention discloses radiation resistant inner wall latex paint, which is prepared from the following raw materials in parts by weight: water, a dispersing agent, a thickening agent, a wetting agent, a defoaming agent, pigment filling materials and octaphenyl caged polysilsesquioxane modified sulfonated polyimides. The invention also discloses a preparation method of the radiation resistant inner wall latex paint.

Description

technical field [0001] The invention belongs to the technical field of latex paint, in particular to a radiation-proof interior wall latex paint. Background technique [0002] Interior wall latex paint is widely used in people's lives. Currently used interior wall latex paint formulations generally use organic solvents as film-forming aids and other additives. Organic solvents are volatile and will pollute the environment and endanger human health. Moreover, the existing film-forming aids and other aids have poor ultraviolet resistance and poor weather resistance, and are easy to crack, fade, and bloom after being irradiated by ultraviolet rays. In addition, thermal expansion and contraction are often different, which leads to cracking and peeling of the paint surface or paint surface. At the same time, the existing interior wall latex paint does not possess radiation protection and stain resistance. [0003] Therefore, it is very necessary to improve the formula to provi...
