Abstract
The present invention relates to a formula of nano-antibacterial paint and a production technology, which is characterized in that the nano-antibacterial paint is basically composed of titanium white powder and nano-silicon oxide antibacterial agents. The nano-antibacterial paint is prepared from the nano-silicon oxide antibacterial materials which have the advantages of high efficiency, high endurance, stabilization, broad spectrum and high safety on the basis of environmental protection type water-soluble acrylic paint by an advanced processing technology. The nano-antibacterial paint after film forming and drying can form a silica network structure which has the advantages of high compactness, strong malleability and washing resistance on a wall body.
Description
Affiliated technical field
The present invention relates to a kind of prescription and production technique of nano antibacterial coating.
Background technology
The inner wall of building face adopts coating to do facing, be the easiest in the various facing practices, the most economical, be most widely used a kind of.But, often cause that inner wall surface coating is mouldy, germ etc. grows along with the deterioration of industrial expansion, environment.As, food-drink production plant metope, because nutritious, temperature, humidity suit, and are easy to breed bacterium, mould and then contaminated food products, leave a legacy of trouble to the crowd; Also have the room of southern high-temperature high humidity, metope etc. are also bred mould easily, not only influence attractive in appearance but also be harmful to health; Particularly hospital, kindergarten if seldom sterilize, owing to carry disease germs in surfaces such as metope, very easily cause personnel's contagious infection.Media report is arranged: China has 5,000 ten thousand people's hospital cares every year approximately, wherein there are 5,000,000 people that cross infection in hospital takes place approximately, about 10,000,000,000 Renminbi of the financial loss that causes are traced it to its cause, and the cross infection that causes very major part is caused by surperficial contagious infections such as interior walls.Though adopt the method add physics or chemistry can reach the surface sterilization germicidal action, often have deficiencies such as bad smell, drug effect weak point, inconvenient operation, physical method one-time investment are big.Therefore, research and develop a kind of interior wall coating of efficient, nontoxic, antimycotic antiseptic with excellent durability, the requirement of satisfying people's disease-prevention health is very necessary.
Summary of the invention
The objective of the invention is on the basis of environment-friendly water-soluble acrylic coating, develop can on body of wall, form after a kind of film forming drying have high compactness, the antibiotic dope for inner wall of architecture of the silica network structure of strong ductility, abrasion resistance.
The technical scheme of nano antibacterial coating of the present invention is characterized in that: each composition weight proportioning of this antibiotic paint prescription is: titanium dioxide 25-40%, nano silicon oxide antiseptic-germicide 2-8%, pure-acrylic emulsion 35-55%, ultrafine heavy calcium 3-15%; 1288 sodium polyacrylate dipersant 0.2-1%, 2,2,4-trimethylammonium-1,3-pentanediol mono isobutyrate film coalescence aid 0.5-2%, ethylene glycol 0.2-1.5%, methylcellulose thickener or sodium polyacrylate thickening material 0.1-0.3%, polyethylene glycol type defoamer 0.1-0.4%, water purification 8-25%.
The processing step of producing nano antibacterial coating is: the weight proportion according to prescription takes by weighing titanium dioxide, ultrafine heavy calcium, dilute with water purification, add ethylene glycol and 1288 sodium polyacrylate dipersants and carry out high speed dispersion stirring and grinding, material after grinding is put back to stirrer add pure-acrylic emulsion sequentially, 2,2,4-trimethylammonium-1,3-pentanediol mono isobutyrate film coalescence aid and scattered in advance nano silicon oxide antiseptic-germicide, methylcellulose thickener or sodium polyacrylate thickening material, polyethylene glycol type defoamer etc. stirs, and notices that constantly adjusting the pH value in the whipping process is 9-10; After waiting to be uniformly dispersed, promptly make this product.The nano oxidized silicon antibacterial material that the present invention is efficient by introducing, lasting, stable on the basis of the environment-friendly water-soluble coating of mainly being made up of titanium dioxide, wide spectrum, security is good is aided with that advanced person's complete processing develops.The advantage of this antibiotic paint mainly is: can effectively solve traditional interior wall coating moisture-sensitive, easily breed bacterium, problem such as mould and overcome and use physics or chemical process that interior wall is carried out the bad smell that surface sterilization brought, drug effect is short, inconvenient operation, the big deficiency that waits of physical method one-time investment, when using, the present invention can on body of wall, form a kind of silica network structure after the film forming drying, it has high compactness, strong ductility and abrasion resistance, be a kind of efficient, nontoxic, interior wall coating with antimycotic antiseptic of excellent durability is very favourable to people's disease-prevention health.

Embodiment two:
Taking by weighing raw material by weight ratio is: titanium dioxide 32g, ultrafine heavy calcium 8g, water purification 11.4g, ethylene glycol 0.5g, 1288 sodium polyacrylate dipersant 0.5g, pure-acrylic emulsion 42g, 1g2,2,4-trimethylammonium-1, the 3-pentanediol mono isobutyrate, polyethylene glycol type defoamer 0.2g, its processing step is with embodiment one.
All the other embodiment see accompanying drawing one.
The present invention is novel; can effectively solve traditional interior wall coating moisture-sensitive, easily breed problem such as bacterium, mould and overcoming and use physics or chemical process that interior wall is carried out deficiencies such as bad smell, drug effect weak point, inconvenient operation, physical method one-time investment that surface sterilization brings are big, help the protection of environment and people's disease-prevention health.
