Embodiment 1

[0035] Components (weight) of energy-saving and environmentally friendly interior wall paint:

[0036]

[0037] The polyurethane dispersion adopts Archsol from Wanhua Chemical Group Co., Ltd. TM 8558 aliphatic water-based polyurethane dispersion, which is anti-yellowing, anti-hot sticking, delicate and soft to the touch.

[0038] The wetting agent is DOW's BD109, zero VOC, and does not contain APEO.

[0039] The dispersant is Orotan 1124 from DOW, which has excellent dispersing ability to titanium dioxide.

[0040] The rutile titanium dioxide is DuPont's R706.

[0041] The diatomite is Celite MW25, which is porous, high in porosity, light in weight, large in specific surface area and high in whiteness.

[0042] The expanded microspheres are AKZO's 461WE40d36, which has low specific gravity, low thermal conductivity and soft touch.

[0043] Coasol dibasic acid dibasic ester from DOW is used as the film-forming aid, which has a low odor and a boiling point of 287°C.
