Embodiment 1

[0046] (1) Preparation method of formic acid microcapsules

[0047] a. Add 5 parts of toluene and 1.5 parts of ethanol to a three-necked flask with a reflux device, and slowly add 7 parts of ethyl cellulose to disperse until completely dissolved in a constant temperature water bath at 70-75°C and at a speed of 300-500r / min. Disperse for 5 to 10 minutes to obtain a dispersion; then slowly add a mixture of 18 parts of formic acid and 27 parts of curing agent urea into the dispersion; slowly add non-solvent petroleum ether under stirring until the ethyl cellulose coagulates, stop heating; placed, naturally cooled to room temperature, filtered, washed, and dried to obtain ethylcellulose-coated microcapsules;

[0048] b. Put 20 parts of water into the three-necked flask, heat it to 60°C, slowly add 6 parts of sodium alginate while stirring, after the sodium alginate is completely dissolved, add 18 parts of microcapsules coated with ethyl cellulose, and continue stirring After 10 m...

Abstract

The invention discloses an aerosol type wax-free paint remover. A formula of the aerosol type wax-free paint remover comprises the following components in parts by weight: 16.0 to 24.0 parts of an environment-friendly high-boiling-point solvent AGSE, 2.0 to 6.5 parts of solvent oil, 0.8 to 3.6 parts of ethylene glycol monophenyl ether, 2.0 to 4.0 parts of propylene glycol monomethyl ether, 26.0 to40.0 parts of dichloromethane, 5.0 to 12.0 parts of methanol, 2.0 to 9.0 parts of formic acid microcapsules, 1.5 to 3.5 parts of a thickening agent and 12.0 to 26 parts of a propellents. With adoption of the technical scheme, the paint remover has the following advantages: 1, a low-boiling-point solvent and a high / medium-boiling-point solvent are compounded to cooperatively reduce the volatilization speed rate and achieve extremely high dissolving power and penetrability; 2, by dual formic acid microcapsulation, a tank body is prevented from being corroded by formic acid, a paint removing effect is enhanced; and the stability of the product is improved; 3, the thickening agent is added to retard product loss and increase the utilization rate of the product, and no wax is contained, so that influence on recoating after complete flushing is eliminated; 4, by vaporization heat absorption of the propellents, the surface temperature of a workpiece is reduced, the volatilization speed of the product is low, and the characteristics of flexibility and convenience for construction and good atomization are achieved.

Description

technical field [0001] The invention relates to a coating or paint film removal technology, in particular to an aerosol-type wax-free paint remover with low volatilization speed, high-efficiency paint removal, and fast flushing of residues without affecting the recoating of substrates. Background technique [0002] Paint is a kind of coating that can form a coating film on the surface of an object, and has protection, decoration, marking and other special functions. With the development of my country's economy and the progress of science and technology, coatings will provide more and more perfect and powerful functions at more levels. However, the coating is damaged during use, the coating is aging, or needs to be removed and repainted due to individual pursuit of aesthetics and functions. [0003] There are several methods of removing old coatings, including physical and chemical methods. Physical methods include the use of mechanical means to remove the coating on the su...
