Abstract
The invention provides an electrophoretic paint, comprising the following raw materials by weight percent: 95% of epoxy resin and 5% of special assistant for the electrophoretic paint. The 5% of special assistant for the electrophoretic paint is added to the 95% of epoxy resin, and the electrophoretic paint is prepared by adopting the existing mature technology and equipment, and the prepared product has a smooth and flat surface, and meanwhile, the dull and heavy surface of a paint film is avoided. Therefore, the requirements of the product are met.
Description
Technical field
The present invention relates to electrophoretic paint production field, be specifically related to a kind of electrocoating paint.
Background technology
Electrocoating paint is divided into ability cathode electrophoresis and anodic electrophoresis; electrophoretic paint as the novel low pollution of a class, economize the energy, resource-saving, rise and protect and the coating of non-corrosibility; there is smooth coating; the features such as water tolerance and chemical resistant properties are good; easily realize mechanize and the automatization of application industry; applicable complex-shaped, there are edge corner angle, hole Workpiece coating, be widely used at present the application of the handwares such as automobile, automatic vehicle, electromechanics, household electrical appliances.Electrophoretic paint and finishing obtain industrial application after the sixties in 20th century, adopt electrophoretic paint can carry out the operation of closed circulating system, and coating almost 100% utilizes.Electrophoretic paint is taking water-soluble or water dispersible Ionomer as film forming matter, and being coated with workpiece can be that anode also can be used as negative electrode; Existing coating surface unfairness, and surface ratio is more dull and heavy, does not reach attractive in appearance and practical requirement.
Summary of the invention
For above problems of the prior art, the invention provides a kind of electrocoating paint, make the surface ratio of product more smooth, avoided the dull and heavy of coating surface simultaneously.
The present invention is achieved by the following technical solutions:
A kind of electrocoating paint, formed by epoxy resin, electrocoating paint special assistant, compound alcohol ether, pigment and filler, the mass percent of wherein said epoxy resin is 75-81%, the mass percent of electrocoating paint special assistant is 4-5%, the mass percent of compound alcohol ether is 1%, the mass percent of pigment is 12-17%, and the mass percent of filler is 2%.
Electrocoating paint special assistant is propyl carbinol and compound alcohol ether, and the mass ratio of propyl carbinol and compound alcohol ether is 3:2.
Compound alcohol ether is propylene glycol monomethyl ether, butyl glycol ether |, Diethylene Glycol butyl ether or diethylene glycol dimethyl ether.
Pigment is carbon black or titanium dioxide; Filler is kaolin and matting agent.
Preparation method:
1) epoxy resin and electrocoating paint special assistant are mixed to thick, form work in-process;
2) use shredder to grind fully the work in-process in step 1 and compound alcohol ether, pigment and filler;
3) product after grinding fully in step 2 is mixed with water as required, obtain required finished product.
The temperature that step 1 stirs is 40-50 DEG C, and pressure is normal pressure.
Beneficial effect of the present invention is: in the epoxy resin that is 95% in mass percent, adding mass percent is 5% electrocoating paint special assistant, adopt existing proven technique equipment to be prepared, kaolin can suspend the product of grinding and be difficult for precipitation, therefore product can be kept to the state mixing, also more even in adhering to product; Therefore the product of preparing makes the surface ratio of product more smooth, has avoided the dull and heavy of coating surface simultaneously.
