Abstract

The invention discloses a reflective fast-curing antibacterial coating, which is prepared from the following raw materials in percentage by weight: 4-6% of magnesium acetylide, 25-35% of fluorocarbon emulsion, 5-12% of nano hollow glass fiber, 12-15% of titanium dioxide, 0.7-1.0% of an UV cured light initiator, 0.5-0.9% of a defoaming agent, 0.5-1.0% of a preservative, 20-30% of an antibacterial modified resin and a nano silicon solution in a weight ratio of 30:1, and 21-32% of deionized water. The heat insulation property and antibacterial property of the coating disclosed by the invention are good, and the curing speed of a film is rapid.

Description

A kind of reflectivity fast setting antibiotic paint

Technical field

The present invention relates to reflectivity fast setting antibiotic paint.

Background technology

In each field, widely, as on exterior wall, industrial warehouse, chemical industry, oil, food service industry class basin and pipe surface, the buildingss such as factory building, modernization plant, freezer, house owed by a citizen, office building are first-class in the application of coating.

Tradition is all the coating for organic solvent, the contaminative of this coating is serious, therefore, now everybody big area bring into use water-borne coatings, and for exterior coating, need the wherein important technological problems solved to be heat insulation and antibacterial, but existing water-borne coatings it is not heat insulation all good enough with anti-microbial property.In order to improve operating efficiency, the curing speed of coating also very important.

Summary of the invention

In order to improve heat insulating reflecting performance, curing speed and germ resistance, the invention provides a kind of reflectivity fast setting antibiotic paint.

For achieving the above object, a kind of reflectivity fast setting antibiotic paint, according to weight percent meter, is prepared from by following raw material;

Magnesium carbide 4%-6%

Fluorine carbon emulsion 25%-35%

Nano-hollow glass fibre 5%-12%

Titanium dioxide 12%-15%

UV solidifies light trigger 0.7%-1.0%

Defoamer 0.5%-0.9%

Sanitas 0.5%-1.0%

Weight percent is antibacterial modified resin and the nano-silicon solution 20%-30% of 30:1

Deionized water 21%-32%.

Further, described defoamer is selected from a kind of in SP-202, XP-1273 or their mixture, and described sanitas is nitrite.

The invention has the beneficial effects as follows: owing to adding magnesium carbide, nano-hollow glass fibre and titanium dioxide, therefore, infrared reflectance can reach more than 90%, and heat insulation rate to 98%, thus can improve effect of heat insulation.By coatings of the present invention on body of wall, due to the interaction of antibacterial modified resin, nano-silicon solution and fluorine carbon emulsion, make the anti-microbial property of this coating good, and have good heat-proof quality, the hardness of paint film is high, good toughness.UV solidifies the UV-light that light trigger energy absorb light wavelength is 250 ~ 420 nm, can resolve into biologically active fragment trigger monomer polymerization then, thus improve the speed of solidification greatly after absorbing luminous energy.

Embodiment

Below in conjunction with specific embodiment, the present invention is further elaborated.

Reflectivity fast setting antibiotic paint, according to weight percent meter, is prepared from by the antibacterial modified resin that 4%-6% magnesium carbide, 25%-35% fluorine carbon emulsion, 5%-12% nano-hollow glass fibre, 12%-15% titanium dioxide, 0.7%-1.0%UV solidify light trigger, 0.5%-0.9% defoamer, 0.5%-1.0% sanitas, 20%-30% weight percent are 30:1 and nano-silicon solution, 21%-32% deionized water.Wherein, described defoamer is selected from a kind of in SP-202, XP-1273 or their mixture, and described sanitas is nitrite.
