Abstract
The invention discloses a kind of low-temperature curable powder coating, metaphenylene unsaturated polyester resin 50-60, E-12 epoxy resin 20-25 that it is made up of the raw material of following weight parts, white carbon black 0.1-0.5, lanthanum trioxide 3.5-4.5, activity charcoal powder 10-13, Diisopropyl azodicarboxylate 1-2, water glass 2-3, ferrous sulfate 2-3, resol 1-2, dimethyl silicone oil 0.1-1, compounded mix 10-20; Low-temperature curable powder coating provided by the invention, transparency is high, and solidification value is low, in spraying process, to object thermal pretreatment to 50-70 DEG C, keep 5-8 minute, carry out electrostatic spraying, then through the hot blast 20min of about 120 DEG C, naturally cooling and get final product, be applicable to the application of timber, any surface finish bubble-free, good film-forming property.
Description
Technical field
The present invention relates generally to a kind of coating, particularly relates to a kind of low-temperature curable powder coating.
Background technology
Its characteristic of powder coating has: 1, this product is not containing toxicity, containing solvent with containing the virose material that volatilizees, therefore without poisoning, without the problem of the public hazards such as discharge of fire, nothing " three wastes ", meet the requirement of national environmental protection method completely.2, utilization rate of raw materials is high, and the powder of the powder supplies business production of some famous brand names, it crosses the powder recoverable of spray, and the highest utilization ratio even can reach more than 99%.3, after coated article pre-treatment, one-off construction, without the need to primary coat, can obtain the film of adequate thickness, easily realize automated operation, production efficiency is high, can reduce costs.4, coating densification, sticking power, resistance to impact shock and toughness are all good, and corner coverage is high, have excellent resistance to corrosive chemicals energy and electrical insulation properties.5, powder coating storage, transportation safety and convenience.
Summary of the invention
The object of the invention is exactly to provide a kind of low-temperature curable powder coating.
The present invention is achieved by the following technical solutions:
A kind of low-temperature curable powder coating, is characterized in that what it was made up of the raw material of following weight parts:
Metaphenylene unsaturated polyester resin 50-60, E-12 epoxy resin 20-25, white carbon black 0.1-0.5, lanthanum trioxide 3.5-4.5, activity charcoal powder 10-13, Diisopropyl azodicarboxylate 1-2, water glass 2-3, ferrous sulfate 2-3, resol 1-2, dimethyl silicone oil 0.1-1, compounded mix 10-20;
Described compounded mix is made up of the raw material of following weight parts:
Gibbsite 30-40, attapulgite 20-30, silicon carbide 6-10, magnesium hydroxide 3-5, carboxymethyl cellulose 1-2, Jojoba oil 2-3;
By above-mentioned gibbsite, attapulgite, silicon carbide mixing, insulation calcining 2-4 hour at 600-800 DEG C, send in ball mill after discharging cooling and carry out ball milling mixing, add magnesium hydroxide and carboxymethyl cellulose again, continue ball milling 1-2 hour, add after Jojoba oil being heated to 25-30 DEG C, ball milling, cross 80-100 mesh sieve, obtain described compounded mix.
A preparation method for low-temperature curable powder coating, comprises the following steps:
By above-mentioned each raw material mixing except white carbon black, send into high-speed mixer, 800-1000 rev/min of dispersed with stirring 3-5 minute, send into forcing machine, melt extrude, be then placed in shredder, add white carbon black, speed lapping under 1000-1200r/min is the screen cloth of 80-100 μm after pore size, obtains described low-temperature curable powder coating.
Advantage of the present invention is:
Low-temperature curable powder coating provided by the invention, transparency is high, good dispersity, solidification value is low, in spraying process, to object thermal pretreatment to 50-70 DEG C, keep 5-8 minute, carry out electrostatic spraying, again through the hot blast 20min of about 120 DEG C, naturally cooling and get final product, is applicable to the application of timber and plastics, any surface finish bubble-free, good film-forming property.
