Embodiment 1

[0016] A waterproof and weather-resistant powder coating, made of the following raw materials in parts by weight:

[0017] Drying oil alkyd resin 49, polyamide polyamine epichlorohydrin resin 18, disteardimethylammonium hectorite 3.5, sericite powder 8, azobisisobutyronitrile 1, sodium lignosulfonate 2 , trimethylhexamethylenediamine 2, coumarone resin 1, organic silicone quaternary ammonium salt 0.6, composite filler 7;

[0018] Described composite filler is made up of the raw material of following weight part:

[0019] Stalactite 18, activated clay 14, light calcium carbonate 7, zinc oxide 3, carboxymethyl cellulose 1;

[0020] Mix the above-mentioned stalactite, activated clay, and light calcium carbonate, and calcinate at 800°C for 2 hours. After the discharge is cooled, send it to a ball mill for ball milling and mixing, then add zinc oxide and carboxymethyl cellulose, and continue ball milling for 1 hour. 100 mesh sieve to obtain the composite filler.

[0021] The pre...

Abstract

The invention discloses water-proof and weather-proof powder coating. The water-proof and weather-proof powder coating is prepared from the following raw materials including, by weight, 42-55 parts of drying oil alkyd resin, 16-23 parts of polyamide polyamine epoxy chloropropane resin, 2.5-3.8 parts of disteardimonium hectorite, 7-9 parts of sericite powder, 1-2 parts of azodiisobutyronitrile, 2-3 parts of sodium lignin sulfonate, 1-3 parts of trimethyl hexamethylene diamine, 1-2 parts of coumarone-indene resin, 0.1-1 part of organic silicone quaternary ammonium salt and 5-8 parts of composite fillers. Meanwhile, the invention provides a preparation method for the water-proof and weather-proof powder coating. The water-proof and weather-proof powder coating provided by the invention is high in transparency and good in dispersity. The water-proof and weather-proof powder coating can be applied to durable protective decoration industry such as factory equipment and facility, aluminum curtain wall and television emission tower coating through excellent water-proof, weather-proof and high-decorative properties thereof and can also be widely applied to the fields of building materials such as bridges, doors and windows, enclosures and domestic tinting materials.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a waterproof and weather-resistant powder coating and a preparation method thereof. Background technique [0002] Powder coating is a new type of solvent-free, pure solid powder coating composed of polymers, pigments and additives; it has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. Powder coatings have a high usage rate because they do not emit volatile organic compounds. In the past 10 years, the development speed of powder coatings in the world has been very fast, with an average annual growth rate of 8%-15%. However, the current powder coating still has defects such as the combination of the coating and the metal texture being not as clear as that of the paint, the heat dissipation of the powder coating is not good enough, and the waterproof and weather resistance performance is...
