Abstract
The invention relates to a modified nano-cuprous oxide coating additive and a preparation method thereof and belongs to the technical field of building coatings. Nano-cuprous oxide particles are prepared by using a chemical precipitation method and then subjected to organic modification by using an organic modifier 3-(methacryloxy) trimethoxypropylsilane (TMSM) to obtain the modified nano-cuprous oxide coating additive. The preparation method has the advantages of being simple in production condition and low in cost. The nano-cuprous oxide particles are subjected to photo-catalytic oxidation under visible light and added to conventional coatings, and the additive is suitable for removing toxic gases such as formaldehyde, benzene and ammonia which are released by decorative materials and various indoor mycete, viruses, lampblack gases, Freon and Freon substitutes, and the additive has the obvious advantages of being mould-proof and capable of killing bacteria, removing odors and purifying indoor air.
Description
Technical field
The invention belongs to the technical field of building coating, be specifically related to a kind of modified Nano Red copper oxide paint additive and preparation method thereof.
Background technology
Building coating is various at present, and particularly the pollution of house decorative material and furniture is the main aspect that causes room air pollution.The toxic gas such as the formaldehyde that finishing material discharges, benzene class, ammonia and indoor various moulds, virus, cooking fume, freonll-11, freonll-11 sub etc. have badly influenced people's healthy and living environment.Along with the fast development of China's economy and the gradually enhancing of people's environmental consciousness, people are more and more higher to the requirement of indoor environment especially room air.
Therefore, it is significant to improving the health of people level to remove indoor harmful gas, people generally take two kinds of methods to reduce indoor harmful gas, and the one, can utilize natural ventilation or power ventilation to improve Air quality, another kind of then be the material of use indoor purifying air.The paint additive that relates at present has a lot, and such as tourmaline indoor air modifying agent (paint partner) and the making method (publication number is CN 1O1513537A) of Guo Keming application, the method selection is difficult and only can utilize far infrared rays in the sunlight; Equally also there are some to reach the interior wall coating for purifying indoor air that purifies air by light-catalyzed reaction, such as a kind of interior photocatalytic coating of University of Fuzhou application and its preparation method and application (application publication number is CN 1O2220039A), but this coating producing process is special, cost is expensive, popularizes so can not get market.
Summary of the invention
The object of the present invention is to provide the preparation method that can issue in the visible light effect a kind of modified Nano Red copper oxide paint additive of third contact of a total solar or lunar eclipse katalysis, be applied in the conventional coating, have easy production, cheap, mildew-resistant, sterilization, deodorizing, the remarkable advantage such as purify the air of a room.
To achieve these goals, the technical solution adopted in the present invention is:
The present invention is a kind of modified Nano Red copper oxide paint additive, is comprised of modified Nano Red copper oxide.
A kind of preparation method of modified Nano Red copper oxide paint additive, by carrying out nano cuprous oxide organically-modified, obtain to issue in the visible light condition modified Nano Red copper oxide paint additive of third contact of a total solar or lunar eclipse catalyzed reaction, the advantage that this additive has mildew-resistant, sterilization, deodorizing, purifies the air of a room.
The method for preparing above-mentioned modified Nano Red copper oxide paint additive, to use first chemical precipitation method synthesis of nano Red copper oxide particle, then get a certain amount of above-mentioned Red copper oxide and in distilled water, carry out ultra-sonic dispersion, form metastable Red copper oxide slurries, with organic modifiers 3-(methacryloxy) propyl trimethoxy silicane (TMSM) joins in the nano cuprous oxide slurries, mechanical stirring obtains slurries suction filtration, drying in the Red copper oxide of modification after reaction for some time; After more above-mentioned modified oxidized cuprous grinding, high speed dispersion being become finely powdered, make modified Nano Red copper oxide paint additive.
