Description
Technical field
The present invention relates to a kind of new coating in the new chemical materials field, mainly is the production technical field for the anti-corrosive powder paint of the saving resource of auto parts machinery and environment-friendly type.
Background technology
Still there are very big gap in some gordian technique and the advanced country of domestic automobile production at present; especially with the technology of the desired energy-saving, emission-reducing, environment friendly of situation aspect the corrosionproof protection of the vehicle body of automobile and spare and accessory parts; the a large amount of powder coating that economize on resources with environment amity that adopt of American-European countries; particularly popularize powder coating on the accessories such as automobile chassis, support, rim, spring; yet China's conduct is powder coating big producing country in the world; turnout account for world wide production half, also account for simultaneously half of world consumption amount as powder coating consumption big country.Along with the raising of China's automobile production amount, also more and more higher to the requirement of vehicle product quality, the specification of quality of auto parts machinery is also improved constantly.In various auto parts machineries; some accessory has different particular requirements in the material of steel; in order to guarantee its mechanical characteristics; all to be undertaken anticorrosion and the decoration protection by the application of coating; most of solvent based coating that adopts is that the master carries out application and protection at present, makes use and powder coating on a small quantity.
At present in the application of solvent based coating, use contains the coating of 50% solvent, this coating uses a large amount of poisonous organic solvents, and these solvents all are discharged in the atmosphere in coating process, not only cause the pollution of atmosphere and environment, cause the waste of resource, cause certain harm to the application operator are healthy simultaneously.Also have antiseptic property and the water resistance of water-borne coatings not ideal, also need sewage treatment equipment, cause the pollution of water quality easily.For water-borne coatings, because the singularity of water-borne coatings structure is not so good as solvent based coating aspect protection against corrosion and water tolerance.
Summary of the invention
The present invention seeks to propose a kind of to environment and application operator can not work the mischief, recyclable, and the compactness of filming is good, the anticorrosion and weathering resistance polyester powder coating of the mechanical property of filming and the auto parts machinery of corrosion resistance and good.
The present invention is made up of resin, solidifying agent, pigment, filler and auxiliary agent, and wherein resin, solidifying agent, pigment and filler, auxiliary agent account for described coating total mass per-cent and be respectively 60～68%, 3～5%, 25～32% and 3～5%.
The present invention does not contain organic solvent and water, can not cause the harm of environmental pollution and HUMAN HEALTH; Powder coating sprays ease when application coating can reclaim usefulness again, and the utilization ratio of coating can reach more than 95%, is resource-conserving and environmentally friendly coating variety.Application can reach needed coating thickness together in addition, and the compactness of filming is good, and the mechanical property of filming and corrosion resistance nature are all good, and powder coating is the optimal coating variety of application auto parts machinery.
Resin of the present invention is unsaturated terminal carboxyl polyester resin.
Solidifying agent of the present invention is triglycidyl isocyanurate, hydroxyalkyl amide.
Pigment of the present invention is non-poisonous antirust pigments such as aluminium triphosphate, titanium-iron powder, to replace leaded and poisonous rust-stabilising pigment chromium.
Filler of the present invention is mica powder or silicon powder.
Auxiliary agent of the present invention comprises flow agent, air release agent, dispersion agent, the modification thermoplastic resins such as elastic polyethylene, polyvinyl butyral acetal and polymeric amide of filming, and improves the nano silicon of the chemical resistance of filming.
Embodiment
One, production technique can adopt general processing step:
(1) by the pre-mixing on high-speed mixer of the load weighted raw material of prescription.
(2) melt extrude mixing with twin screw extruder, cooling is broken into coating agent which has to be dissolved in alcohol before use then.
(3) it is broken to carry out fine powder with air classifying mill (ACM mill), and to mean particle size is 35～40 microns powder coating product with the rotating screen sieving separating.
Two, raw material: vibrin of the present invention is unsaturated terminal carboxyl polyester resin; Solidifying agent is triglycidyl isocyanurate, hydroxyalkyl amide etc.; Pigment and filler are to use non-poisonous antirust pigment and the filler of good antirust property, for example filler of non-toxic pigment such as aluminium triphosphate, titanium-iron powder and good antirust property such as mica powder, silicon powder; Auxiliary agent uses general powder coating flow agent commonly used, air release agent, dispersion agent etc., use thermoplastic resins such as improving film snappiness and elastic polyethylene, polyvinyl butyral acetal, polymeric amide, also added the nano silicon that improves the chemical resistance of filming especially.
Three, production example:
Example 1: take by weighing unsaturated terminal carboxyl polyester 68 kg, triglycidyl isocyanurate 5 kg, aluminium triphosphate 5 kg, silicon powder 12 kg, tinting pigment 3 kg, flow agent 1 kg, dispersion agent 1 kg, air release agent 0.3 kg, nano silicon 0.7 kg, thermoplastic resin 4 kg respectively.
Form the anticorrosion and weather-proof epoxide powder coating A that uses of 100kg auto parts machinery by above explained hereafter.
Anticorrosion and the weather-proof baking-curing condition with epoxide powder coating A of auto parts machinery is: 200 ℃/10min; Film performance reaches shock strength 50Kgcm, snappiness 1mm, salt spray resistance 1200h, the 1200h of anti-the artificial weathering.
