Embodiment 1

[0017] A kind of preparation method of coating composition, coating component is made of following weight components:

[0018]

[0019] Its preparation method specifically comprises the following steps:

[0020] Take polyvinyl acrylate emulsion and part of water according to the formula and add it to the container, heat it in microwave to 35°C, keep the temperature constant, then add nano-aluminum powder, calcined magnesia, bentonite, nano-calcium oxide and nano-titanium oxide in sequence under ultrasonic , sonicate for 20min, the frequency is 200HZ, the power is 650W, then add the remaining part of water, and stir for 25min under mechanical stirring, the stirring speed is 1100r / min.

[0021] Apply the above paint on A3 steel, investigate the high temperature resistance performance at 1800 degrees Celsius and test its corrosion resistance effect in 3% NaCl solution, the results are as follows:

[0022] Antiseptic effect (3% NaCl solution, test period 1 year)

Abstract

The invention discloses a preparation method of a coating composition. A coating consists of the following components in parts by weight: 21 parts of nano aluminum powder, 19 parts of calcined magnesia, 2 parts of bentonite, 8 parts of water borne epoxy resin emulsion, 12 parts of nano-calcium oxide, 8 parts of nano-titanium oxide and the balance of water. In the assistance of ultrasonic waves and microwave heating, the overall performance of the coating can be enhanced; and the prepared coating has wide application, is corrosion-resistant and erosion-resistant, and can be used at certain temperature.

Description

technical field [0001] The invention relates to a preparation method of a paint, in particular to a preparation method of a paint which is anti-corrosion, corrosion-resistant and resistant to a certain temperature. Background technique [0002] With the development of the national economy and high technology, the demand for special coatings is increasingly urgent in addition to general-purpose coatings. Among anti-corrosion coatings, peroxide ethylene coatings, epoxy resin coatings, and oxysulfonated polyethylene coatings all exist concurrently, but each has its own shortcomings. Ethylene peroxide paint came out in the early 1970s. This kind of paint has a certain anti-corrosion effect, but due to the large molecular weight, the leveling property is not ideal, the solid content is low, generally only 14-18%, the paint film density is poor, and the viscosity is also very high. Low, only 20-50 seconds, its adhesion is not good, and the paint film is easy to fall off. [0003...
