Description

A kind of waterborne metallic paint

Technical field

The present invention relates to a kind of coating, be specifically related to a kind of waterborne metallic paint.

Background technology

At present, the metallic paint of some high-qualitys is because its coverage effect is good, bright in color, and known and like by people, but the metallic paint of these high-qualitys generally adopts the batching of some high-qualitys, just can reach good effect, and these batchings have increased manufacturing cost greatly, and a series of quality problems such as rear metope surface peeling, shedding, peeling be full of cracks, moldy metamorphism and some common metallic paint ubiquities make moist make the user enjoy puzzlement.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of low cost of manufacture, the stay-in-grade waterborne metallic paint.

The present invention is achieved through the following technical solutions: a kind of waterborne metallic paint, its formula forms acrylic resin, methyl-etherified aminoresin, high-carbon black pigment, talcum powder, process white, kaolin, polyphosphoric acid aluminium, wilkinite, propandiol butyl ether and auxiliary agent, and its formula forms as follows by weight percentage:

Its preparation method is as follows:

Step 1) at first deionized water and propandiol butyl ether are mixed;

Step 2) with step 1) in the mixed solution that obtains join in acrylic resin, methyl-etherified aminoresin, high-carbon black pigment, kaolin, wilkinite, and stir by stirrer;

Step 3) with step 2) in add polyphosphoric acid aluminium and auxiliary agent in the mixture that obtains, and add stirring tank to stir;

Step 4) with step 3) resulting mixture is cooled to room temperature.

Further, described auxiliary agent is the mixture of defoamer, flow agent and dispersion agent, and wherein, defoamer, flow agent and dispersion agent respectively account for 1/3rd.

Further, described step 3) the stirring tank stirring velocity in is 700～1200r/min, and temperature is controlled at 60～90 ℃, and churning time is 20min.

The beneficial effect of waterborne metallic paint of the present invention is: its making method is simple, and production cost is low, and nonpoisonous and tasteless, uses to store transportation safety, is conducive to constructor's physical and mental health and environment protection, is one of coating first-selected in the modern life.
