Absorption/decomposition function material is added under stirring at low speed into the mixed solution, is stirred, thickener stirring is added
Homogeneous solution is formed, is then added color stuffing in the homogeneous solution, high-speed stirred is simultaneously ground, and reaches slurry fineness
10 μm~35 μm, coalescents, emulsion, defoamer, thickener and levelling agent are then added into slurry under stirring at low speed, is stirred
Uniform rear filtering is mixed, high-performance indoor air purification aqueous inner wall paint is produced.
10. preparation method according to claim 9, it is characterised in that：The absorption/decomposition function material passes through such as lower section
Method is prepared：
(1) the silicon substrate porous material that particle diameter is 20 μm~50 μm is taken, by silicon substrate porous material：Alkaline solution weight ratio for (100~
150): 1 is added to silicon substrate porous material in alkaline solution, is transferred to afterwards in reactor by evenly mixing, 0.8MPa~
Be calcined under 1.3MPa pressure it is expanded, sintering temperature be 480 DEG C~850 DEG C, roasting time be 1min~10min, take out cooling after
Grinding, screening, obtain the powdered silicon substrate porous material carrier that particle size range is 0.5 μm~30 μm；
(2) by a kind of titanium salt in tetraethyl titanate, butyl titanate, titanium propanolate, isopropyl titanate, titanyl sulfate and anhydrous second
Alcohol stirs 2h~10h in a solvent, and the wherein weight ratio of titanium salt, absolute ethyl alcohol and solvent is 1: (1.5~4): (0.1~0.3),
The solvent is acetylacetone,2,4-pentanedione or glacial acetic acid, after stirring, and adds the ethanol solution that mass fraction is 20%, wherein titanium
The weight ratio of salt and ethanol solution is 1: (0.5~1.2), 5h~24h is stood, nanometer mixed crystal TiO is formed2Colloidal sol；
(3) silicon substrate porous material carrier obtained by step (1) is cleaned by ultrasonic, then quickly inserts nanometer obtained by step (2)
Mixed crystal TiO2In colloidal sol, after immersion 2min~10min, filtering, after filter cake is dried in the shade naturally, be put into drying box 100 DEG C~
10min~30min is dried at 150 DEG C, then is inserted in Muffle furnace, 500 DEG C~550 DEG C roasting temperature 30min~60min, from
So taken out after cooling, grinding, screening, obtain particle diameter and be loaded with nanometer mixed crystal titanium dioxide for 0.5 μm~30 μm powdered
Silicon substrate porous material, as described absorption/decomposition function material.
