Problems solved by technology

[0004] However, acrylic resin coatings with a linear structure are thermoplastic materials, which are prone to "hot stickiness and cold brittleness". At present, the core-shell emulsion polymerization method is often used for improvement.
[0005] The core-shell emulsion polymerization method can reduce the glass transition temperature of acrylate resins and improve the cold resistance of coatings, but for materials used in the fields of building exterior walls, leather coatings, and machinery, they are used at lower temperatures. The law has some flaws

Abstract

The invention discloses a preparation method for an aircraft leather cushion finishing agent and a building external wall coating. The preparation method is characterized by comprising the following steps: adding de-ionized water, nekal, OS-15 and acrylic acid, raising reaction temperature to 50 DEG C, performing stirring reaction for 40min, adding monomers A, and performing emulsification for 60min; dropwise adding 6.3 grams of a solution of ammonium persulfate for 1h, performing heat-preservation reaction for 1h, adding ethylchlorosilane, isobutyl-triethoxysilane, trifluoropropyl-methyl-dichlorosilane and tetrabutylammonium bromide, and performing reaction for 2h to obtain a shell-layer emulsion; adding azobis(isobutyramidine) hydrochloride into the shell-layer emulsion, performing heat-preservation reaction for 2h at 80 DEG C, adding dioctyl adipate, performing heat-preservation reaction for 2h, lowering the temperature to 60 DEG C, and adding ammonia water to regulate the pH value to 7 to 8, so as to obtain the aircraft leather cushion finishing agent and the building external wall coating. By the obtained coating, the defect of poor aircraft leather cushion finishing agent is overcome.
