Problems solved by technology

The current anti-mildew and preservatives of paints have only a single function, and some preservatives also contain harmful substances such as formaldehyde
Such substances will slowly volatilize into the air, causing long-term pollution to indoor air; in addition, the synthesis process of such additives is often costly and pollutes the environment

Embodiment 1

[0018] Nano-modified auxiliary agent, 30 parts of slurry containing 20% ​​by mass of nano-rutile titanium dioxide, 3 parts of xanthan gum for series of food gums, and the rest is water.

[0019] Add 67 kg of clean water to the paint dispersant, slowly add 3 kg of xanthan gum under stirring, and after becoming a uniform colloidal liquid, add 30 kg of slurry containing 20% ​​nanometer rutile titanium dioxide. kg, after stirring and dispersing, it becomes a uniform colloid, containing 6% of the mass fraction of nanometer rutile titanium dioxide.

Embodiment 2

[0021] Nano-modified auxiliary agent, 30 parts of slurry containing 20% ​​nano-oxide, 10 parts each of nano-titanium dioxide, silver-loaded nano-zirconium phosphate, and nano-zinc oxide, 3 parts of xanthan gum used in series food glue, and the rest water.

[0022] Add 67 kg of treated clean water to the paint disperser, slowly add 3 kg of xanthan gum under stirring, and after it becomes a uniform colloidal liquid, add nano-titanium dioxide, silver-loaded nano-zirconium phosphate, and nano-zinc oxide in sequence 10 parts each of the slurry is 30 kg in total, and after stirring and dispersing, it becomes a uniform colloid, containing 6.0% of the mass fraction of mixed nano-oxides.

Embodiment 3

[0024] Nano-modified auxiliary agent, 30% of slurry containing 20% ​​of nano-oxide, 10 parts each of nano-rutile titanium dioxide, nano-silicon oxide, and nano-alumina, 3 parts of xanthan gum for series food glue, and the rest are water.

[0025] Add 67 kg of treated clean water into the paint disperser, slowly add 3 kg of xanthan gum under stirring, and after it becomes a uniform colloidal liquid, add nano-rutile titanium dioxide, nano-silica, and nano-alumina. 10 parts of each slurry is 30 kg in total, and after stirring and dispersing, it becomes a uniform colloid, containing 6.0% by mass fraction of mixed nano-oxides.

Abstract

The invention relates to an environment-friendly multifunctional nanometer emulsion paint auxiliary agent which comprises, by mass, 1 to 10 parts of food gum, 5 to 50 parts of nanometer slurry, 1 to 15 parts of an assistant and 10 to 60 parts of water, wherein the food gum is xanthan gum, carragheenan, locust bean gum, Arabic gum, konjak gum or a mixture thereof, the nanometer slurry is nanometer titanium dioxide, silver carrying nanometer zirconium phosphate or a mixture of nanometer titanium dioxide or silver carrying nanometer zirconium phosphate and nanometer silicon oxide, nanometer zinc oxide and nanometer alumina, and the assistant is a surfactant, a thickening agent, a dispersant or an antifoaming agent. The invention has the following advantages: a plurality of functions are integrated together, and the effects of mildew resistance, corrosion resistance, sterilization and decomposition of toxic substances in the air are obtained; production cost is low, and a preparation process is simple; since food gum is used and mixed with the nanometer slurry, the advantages of greenness, environment friendliness, no generation of toxic substances and convenient usage are achieved.

Description

technical field [0001] The invention relates to a chemical auxiliary agent, in particular to an environmental-friendly auxiliary agent for nano-emulsion paint. Background technique [0002] The role of additives in traditional latex paint is very important, and it is also the target of competition between domestic and foreign companies. The additives used in coatings are worth tens of billions of dollars every year in the world, and most of the domestic market is occupied by many foreign companies. Most of the additives used in latex paint are harmful to the human body, which has been a matter of great concern to people at home and abroad for many years. With the enhancement of people's advocating nature and environmental awareness, biological and fermented surfactants will have a broader application prospect, and may become a substitute or upgrade for chemically synthesized surfactants. [0003] In the production process of water-based paint, antifungal agents, preservativ...
