Abstract

The invention discloses an attapulgite / nano-strontium-titanate / nano-tin-oxide photocatalysis silicone-acrylic coating preparation method. Tin tetrachloride, strontium acetate and tetrabutyl titanate serve as raw materials, nano-tin-oxide and nano-strontium-titanate are loaded on the surface of attapulgite by a sol-gel method, the attapulgite is modified by photocatalysis, a prepared attapulgite loaded strontium-titanate / tin-oxide composite nano-material has excellent thickening property, leveling property and photocatalysis activity and then serves as a thickening agent and a photocatalyst for preparing a silicone-acrylic coating, and the prepared silicone-acrylic coating has excellent photocatalysis property, good weather resistance, water resistance, chemical resistance, stain resistance, flexibility and adhesiveness.

Description

technical field [0001] The invention relates to a preparation method of attapulgite / nanometer strontium titanate / nanometer tin oxide photocatalyzed silicon acrylic coating, which belongs to the field of coating additives. Background technique [0002] In recent years, with the improvement of people's living standards, indoor environmental problems caused by interior decoration, furniture materials and people's indoor life have increasingly attracted people's attention and attention, and indoor pollution has gradually become a social hot spot. Indoor pollutants mainly include formaldehyde, benzene, ammonia, radioactive substances and volatile organic compounds. Ventilation is usually used to control indoor pollutants. In many places, it is stipulated that new houses must be ventilated for at least three months before occupancy, ensure that there is sufficient sunlight in the room, and use ultraviolet rays in the sun to sterilize; the above methods cannot fundamentally remove ...
