Abstract

The invention discloses an antibacterial powder coating. The antibacterial powder coating is prepared from the following components in parts by weight: 20-30 parts of bisphenol F epoxy resin, 40-50 parts of aliphatic glycidyl ether epoxy resin, 10-15 parts of poly(methyl)acrylic resin with free carboxyl, 10-12 parts of nano silicon, 10-15 parts of antibacterial modified resin, 2-3 parts of fluorocarbon, 2-3 parts of magnesium carbonate, 5-9 parts of rubber powder, 10-15 parts of carbon black, 2-3 parts of alumium powder, 3-5 parts of iron oxide red, 0.3-0.6 part of dibutyltin dilaurate, 3-4 parts of curing agent, 0.7-1.2 parts of stabilizer an 3-4 parts of flatting agent. The antibacterial powder coating is moderate in volume resistance, high in surface resistance and good in antibacterial property.

Description

A kind of antibacterial powder paint
Technical field
The present invention relates to powder coating.
Background technology
At present, along with the develop rapidly of global industry, the environmental problem caused also becomes increasingly conspicuous.How to carry out the important topic that environmental protection work has become urgently people's research.Some western countries development research that Environmental awareness is strong goes out to have the car paint of low volatile organic, and puts into production in a large number and use.Along with the development of automobile industry, in order to beautify the appearance of film of automobile, alleviating the environmental pollution that it causes, improving vehicle spray painting technology and seeming particularly important.
For powder coating, if the volume resistance of powder coating is too high, powder is not easily adsorbed on base material, and volume resistance is too low, causes powder not easily charged.If the surface resistivity of powder coating is too low, be just easy to cause the electric charge being positioned at base material edges and corners to leak, thus the powder coating on base material is come off.In addition, if the anti-microbial property of coating is bad, then can affect the work-ing life after coating film forming.
Summary of the invention
The invention provides a kind of volume resistance moderate, surface resistivity is high, the powder coating that anti-microbial property is good.
For achieving the above object, a kind of antibacterial powder paint, count by weight, by 20-30 part bisphenol F epoxy resin, 40-50 part aliphatic glycidyl ether epoxy resin, 10-15 part, there is poly-(methyl) acrylic resin of free carboxyl group, the nano-silicon of 10-12 part, the antibacterial modified resin of 10-15 part, 2-3 part fluorine carbon, 2-3 part magnesiumcarbonate, 5-9 part rubber powder, 10-15 part carbon black, 2-3 part aluminium powder, 3-5 part red iron oxide, 0.3-0.6 part dibutyl tin dilaurate, 3-4 part solidifying agent, 0.7-1.2 part stablizer and 3-4 part flow agent and form.
Further, described solidifying agent is TGIC.
Further, described stablizer is organic tin stablizer.
Further, described flow agent selects the product of Dow Corning Corporation, and model is 5T.
The invention has the beneficial effects as follows: adopt raw material of the present invention when preparing powder coating, owing to containing aliphatic glycidyl ether epoxy resin in raw material, there is poly-(methyl) acrylic resin, rubber powder, carbon black and the aluminium powder of free carboxyl group, under the effect of dibutyl tin dilaurate, carbon black and aluminium powder is made to deposit in powder, more rubber powder is had to separate out, therefore, make the surface resistivity of powder coating high, volume resistance is moderate, like this, not easily there is charge leakage in the edges and corners of base material in the powder coating of spraying, powder coating is easily attached on base material.Due to the interaction of antibacterial modified resin, nano-silicon and fluorine carbon, make the anti-microbial property of this coating good, and have good heat-proof quality, the hardness of paint film is high, good toughness.
Embodiment
Below in conjunction with embodiment, the present invention is further elaborated.
