Spray paint for outside surfaces of motors and preparation method thereof

Abstract

The invention provides a spray paint for the outside surfaces of motors and a preparation method thereof. The paint comprises the following raw materials in parts by mass: 15-27 parts of linseed oil, 15-25 parts of trimethylolpropane, 15-27 parts of methyl diisocyanate, 2-5.5 parts of sorbic acid, 2-5.5 parts of phthalic anhydride, 0.7-2.5 parts of dioxin, 0.01-0.03 part of ethyl cellosolve, 2-5 parts of aluminum silver paste, 2-4 parts of oxalic acid, 2-4.5 parts of benzoyl peroxide, 3-6 parts of cobalt naphthenate, 0.5-1 part of sodium peroxide, and 6-15 parts of chlorinated rubber. The paint provided by the invention has the properties of excellent adhesion, impact resistance, water resistance, corrosion resistance, difficult sagging, and the like, and has a good protection effect on the surfaces of the motors, thereby prolonging the service lives of the motors.

Description

technical field [0001] The invention relates to a paint, in particular to a spray paint for the outer surface of a motor and a preparation method thereof. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It is represented by the letter M in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. A generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. At present, the most commonly used is to use heat energy, water energy, etc. to drive the generator rotor to generate electricity. [0003] Motors are widely used in industry, but the metal on the surface of the motor is easy to rust, corrode or be damaged by other external factors. Therefore, it is very important to do a good job of anti-corrosion work on the surface...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many coatings used on the surface of motors in the market, but they generally have disadvantages such as poor adhesion, short adhesion time, easy sagging, and poor water resistance.

For example, the Chinese invention patent (patent number 201210327498.3, application date 2012 / 09 / 07) discloses an anti-corrosion coating for electromechanical applications, which has good anti-corrosion performance, long anti-corrosion life, strong adhesion and ecological protection, but Poor water resistance, low hardness, and poor adhesion; Chinese invention patent (patent number 201010218394.X, application date 2010 / 07 / 06) discloses high-solid wear-resistant coatings for wind energy motors and their preparation methods and applications. The paint film has excellent light resistance and weather resistance, strong outdoor exposure durability, good resistance to acid, alkali, salt, grease, detergent and other chemical sticking and corrosion properties, high hardness, and strong wear resistance Performance, the paint film has high gloss, high fullness, good leveling, good adhesion, and good impact resistance, but its water resistance is poor and the adhesion strength is low
