Problems solved by technology

These two kinds of coatings have a common disadvantage, that is, the speed of reaching the surface is relatively slow, and a certain baking process must be added between each coating pass.
This is a big waste for radiator manufacturers, and also reduces production efficiency to a certain extent
In addition, the performance of high temperature water resistance, epoxy resin is also relatively limited

Abstract

The present invention discloses a corrosion resistant paint for the inner surface of radiator and a preparation method thereof, and belongs to the field of paints and paints preparation technology. The paint comprises, by weight, modified acrylic resin 10-80 parts, pigment 5-50 parts, filling material 5-50 parts, diluent 5-60 parts, auxiliary agent 0.1-10 parts, and other resin 0.1-10 parts. The preparation method is as follows: weighing modified acrylic resin, pigment, filling material, auxiliary agent and other resin according to weight parts; stirring the above materials and a diluent together completely by using a high speed stirrer; grinding the mixed material fully by using a sand milling machine; and adding the diluent to the mixed material by using the high speed stirrer to adjustviscosity to be 20-60 s. The said paint has high adhesion, good fluidity, and short surface drying time, thus energy cost is lowered, operation time is shortened, and the resistance to high temperature alkaline water of the paint is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of paint and paint preparation, in particular to a radiator internal anti-corrosion paint and a preparation method thereof. Background technique [0002] The main problem faced by the radiator is internal anticorrosion, that is, how to prevent the high temperature and high pressure boiler water from corroding the inner wall of the radiator, so as to solve the problems of long life and safe operation of the radiator. [0003] With regard to radiator anticorrosion problem, people try to use various methods to solve. These include electro-galvanizing, nickel plating, electroless nickel-phosphorus alloy plating, paint protection, electrochemical cathodic protection, and addition of corrosion inhibitors. However, there are pros and cons to each implementation. Among them, the electrochemical cathodic protection (magnesium anode) method is difficult to ensure that all parts of the radiator are fully protected; e...
