Description
Technical field
The present invention relates to art of powder coatings, specifically, being a kind of three proofings with antifouling, mould proof, fungi-proofing performance
Powdery paints and preparation method thereof.
Background technique
Building coating because of construction is simple, short time limit, work efficiency height, good decorating effect, easy to maintenance built at present as the modern times
Ornament materials is built to be widely used in architectural finish field.Since building coating is exposed to indoor or outdoors for a long time, with the external world
Air environment is in contact, and a large amount of dust, greasy dirt, acidic materials and sand grain object are mingled in air, is easily attached to
External wall or built-in surface not only influence the glossiness and decorative effect of coating surface, can if things go on like this generate on its surface
Mould etching resist declines coating antiseptic performance, or even causes coating cracking.In view of above, Building class coating must have dress
Adorn the performances such as good effect, anti-pollution, ageing-resistant, waterproof, corrosion-resistant.What anti-pollution characteristic solved is to avoid or reduce acidity in air
Substance, dust are to the bonding and erosion of coating surface, once if anti-pollution characteristic is not achieved, then it directly will lead to the corrosion resistant of product
Corrosion can decline, and then accelerate the season cracking of coating.
Antifouling products currently on the market do not have mould proof, antibacterial effect, cannot effectively inhibit the life of mould and bacterium
It produces, so anti-fouling effect is bad, can not really reach the long-term characteristics such as antifouling, fungi-proofing and mould proof.Therefore, it is applied using powder
The building coats of material need the very big manpower of flower and material resources periodically to be cleared up coating surface, clean the main dirt removed on coating
The pollutants such as dirt, mould；Especially skyscraper, cleaning, cleaning not only expend a large amount of manpower and material resources, also for cleanup crew with
Carry out great security risk.
Effectively to solve the problems, such as that building coats are mouldy, clean, increases new function for building coats, save a large amount of people
Work cleaning charge.A kind of antifouling, mould proof, antibacterial three proofings powder coating product is developed, is had very important significance.
Summary of the invention
The present invention is intended to provide a kind of three proofings powdery paints for being provided simultaneously with these three antifouling, mould proof, fungi-proofing characteristics, simultaneously
Additionally provide the preparation method of the powdery paints.When the three proofings powdery paints is used for outdoor application, dirt can be prevented viscous
Attached, fungus growth, bacterial accumulation is not only able to save the cost manually cleaned, while can also greatly reduce the safety wind of cleaning
Danger.
