The invention discloses a fireproof powder paint which is composed of the following components in parts by weight: 10-20 parts of bisphenol F epoxy resin, 30-45 parts of aliphatic glycidol ether epoxy resin, 15-18 parts of poly(methyl) acrylic resin with free carboxyl group, 15-20 parts of FEVE fluorocarbon resin, 4-8 parts of ammonium polyphosphate, 1-2 parts of magnesium carbonate, 4-8 parts of rubber powder, 8-12 parts of carbon black, 3-5 parts of aluminum powder, 3-5 parts of iron oxide red, 5-8 parts of curing agent, 1-2 parts of stabilizer and 1-2 parts of leveling agent. The powder paint has the advantages of moderate volume resistance, high surface resistance and favorable fire resistance.

Description

A kind of fire-proof powdery 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 automotive 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 coating, fire resistance also very important.
Summary of the invention
The invention provides a kind of volume resistance moderate, surface resistivity is high, the powder coating that fire resistance is good.
For achieving the above object, a kind of fire-proof powdery paint, count by weight, poly-(methyl) acrylic resin, 15-20 part FEVE fluorocarbon resin, 4-8 part ammonium polyphosphate, 1-2 part magnesiumcarbonate, 4-8 part rubber powder, 8-12 part carbon black, 3-5 part aluminium powder, 3-5 part red iron oxide, 5-8 part solidifying agent, 1-2 part stablizer and 1-2 part flow agent by 10-20 part bisphenol F epoxy resin, 30-45 part aliphatic glycidyl ether epoxy resin, 15-18 part with free carboxyl group 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, when sprayed coating, 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.The present invention adopts FEVE fluorocarbon resin to coordinate with poly-(methyl) acrylic resin with free carboxyl group, containing as lively as a cricket epoxy group(ing) in product of the present invention, also containing fluoroolefin, hydroxyl etc., it to most of material as timber, metal, glass, plastics, rubber, leather, pottery, fiber etc. have good bonding force.Product after solidification, has excellent chemical resistance, thermotolerance, resistance to acids and bases and good electrical insulating property, has good sticking power, non-corrosibility and physical strength; The present invention has splendid closure, and flame-retardant composition can not move to coat side, and therefore its fire resistance is less by the impact of time and environment.
