Abstract
The invention relates to a scumbling static powder coating and a preparation method thereof. The scumbling static powder coating comprises the following components by weight: 60-70 kg of polyester resin, 4-5 kg of curing agents, 25-40 kg of fillers, 0.1-2 kg of pigments and 2-6 kg of auxiliary agents. The preparation method of the scumbling static powder coating comprises the following steps of: (1) mixing the raw materials according to a formula; (2) extruding at the temperature of 90-100 DEG C; (3) forming and rolling into a sheet of 1-2 mm; (4) crushing, and grading; (5) separating a product through cyclone separation and a stainless steel screen with special meshes; (6) detecting the particle size of the product by using a laser particle analyzer, carrying out electrostatic spraying on the product for 30-40 micrometers, placing into a high-temperature drying oven for curing at 200 DEG C for 10 minutes, and then inspecting. The scumbling static powder coating disclosed by the invention is capable of uniformly covering the bottom without generating the phenomenon orange skin due to small particle diameter.
Description
Technical field
The invention belongs to coating and preparation method, particularly a kind of coating of scumbling electrostatic powder and preparation method.
Background technology
Electrostatic powder coating is the not solvent-laden 100% solid part powder type coating preparation of one.There is solvent-free, pollution-free, recyclable, environmental protection, the saving energy and resource, reduce labor intensity and film physical strength high.Be widely used in household electrical appliances, automobile, boats and ships, pipeline, construction work, outdoor facilities and general industry product etc.Rely on electrostatic absorption principle, by spray gun transmitting atomized powder, be adsorbed to by spraying workpiece, then enter and in hot setting case, carry out film-forming completely.Form even, careful, top coat closely.
In electrostatic powder coating, particle diameter, at 30-50 micron, is prone to orange peel phenomenon at present.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of scumbling electrostatic powder coating and preparation method, its particle diameter is little, can evenly cover at the end, there will not be orange peel phenomenon.
A coating for scumbling electrostatic powder, comprises following component: 60-70kg vibrin, 4-5kg solidifying agent, 25-40kg filler, 0.1-2kg pigment and 2-6kg auxiliary agent.
A preparation method for the coating of scumbling electrostatic powder, comprises the following steps: (1), accurately weighs various starting material according to above-mentioned formula rate, imports in convertible automatic mixing machine and mixes, and mixing time is 8-10 minute; (2), use twin screw extruder the material mixing is melt extruded, extrusion temperature is 90-100 DEG C; (3), the material of extruding is depressed into 1-2mm thin slice with format roll, is transmitting cooling on steel band and pulverizing with breaker roll; (4), pulverize and classification to abrasive dust unit by sheet stock blow-off valve; (5), isolate product through the stainless steel mesh of cyclonic separation and special order number; (6), by laser particle analyzer testing product granularity, and get product and carry out electrostatic spraying 30-40 micron, put into high temperature drying case and carry out 200 DEG C, after within 10 minutes, solidifying, test.
Particle diameter of the present invention is little, can evenly cover at the end, there will not be orange peel phenomenon.
Embodiment
A coating for scumbling electrostatic powder, comprises following component: 70kg vibrin, 5kg solidifying agent, 40kg filler, 2kg pigment and 6kg auxiliary agent.
A coating for scumbling electrostatic powder, comprises following component: 65kg vibrin, 4kg solidifying agent, 30kg filler, 1kg pigment and 3kg auxiliary agent.
A preparation method for the coating of scumbling electrostatic powder, comprises the following steps: (1), accurately weighs various starting material according to above-mentioned formula rate, imports in convertible automatic mixing machine and mixes, and mixing time is 8-10 minute; (2), use twin screw extruder the material mixing is melt extruded, extrusion temperature is 90-100 DEG C; (3), the material of extruding is depressed into 1-2mm thin slice with format roll, is transmitting cooling on steel band and pulverizing with breaker roll; (4), pulverize and classification to abrasive dust unit by sheet stock blow-off valve; (5), isolate product through the stainless steel mesh of cyclonic separation and special order number; (6), by laser particle analyzer testing product granularity, and get product and carry out electrostatic spraying 30-40 micron, put into high temperature drying case and carry out 200 DEG C, after within 10 minutes, solidifying, test.
The middle particle diameter of product electrostatic powder coating is 15-20 micron, and main particle size distribution is 10-25 micron.Make powder coating flat appearance and reach properties, thickness will reach the twice of mean particle size, according to the granularity of electrostatic powder coating product of the present invention, coating thickness reaches 30-40 micron and just can ensure outward appearance and the performance requriements of film, and because granularity is thinner, outward appearance is more smooth, and per kilogram product spray area is larger.The middle particle diameter of electrostatic powder coating is 15-20 micron, and main particle size distribution is 10-25 micron.Make powder coating flat appearance and reach properties, thickness will reach the twice of mean particle size, according to the granularity of electrostatic powder coating product of the present invention, coating thickness reaches 30-40 micron and just can ensure outward appearance and the performance requriements of film, and because granularity is thinner, outward appearance is more smooth, and per kilogram product spray area is larger.
