example 1

[0018] Take sodium carboxymethyl cellulose and grind it through a 200-mesh sieve to obtain sodium carboxymethyl cellulose powder. Add the sodium carboxymethyl cellulose powder to deionized water in a mass ratio of 1:8, stir and mix to obtain sodium carboxymethyl cellulose powder. Cellulose sodium solution, then according to the volume ratio of 1:10, add the mass fraction of 15% ferric chloride solution to the carboxymethyl cellulose sodium solution dropwise, after adding dropwise at room temperature for 25min, then stir and mix at 250r / min 2h, standing and aging for 6h, filtering to obtain a filter cake, and vacuum freeze-drying to obtain modified particles; in parts by weight, weigh 45 parts of formic acid, 25 parts of acetic acid, 45 parts of phenol, 3 parts of organic bentonite, and 1 part of ten Sodium dialkylbenzoate, 0.1 part of benzotriazole and 15 parts of modified particles were placed in an Erlenmeyer flask, stirred and mixed, heated in a water bath at 45°C for 25 min...

Abstract

The invention relates to a preparation method of an environment-friendly micro-evaporative paint stripper and belongs to the technical field of paint strippers. The preparation method comprises the following steps: compounding a prepared sodium carboxymethylcellulose hydrosol and polyvinyl alcohol and coating the same with a solvent; coating the surface of a material needing to be stripped througha gel to form a film; and densely distributing the film in the whole paint stripper liquid level to form a gel coating which closes the whole system to prevent volatilization and escape of light components in the paint stripper system, wherein a paint stripping reaction is carried out in a relatively closed system, so that paint is stripped efficiently, the paint stripping efficiency is improvedeffectively, and the environment friendliness of the paint stripper is improved.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly micro-evaporation paint remover, belonging to the technical field of paint removers. Background technique [0002] During the use of painted objects, the surface is often subject to various mechanical wear and corrosion, resulting in uneven protection, peeling, aging and falling off of the paint film, resulting in the loss of decorative and protective functions of the paint film. In order to meet various To meet the requirements of decoration and product protection, the surface needs to be repainted, which requires the old paint film on the surface to be stripped first to ensure that the repainting has a better effect. As a commonly used industrial consumable, the paint film of enameled wire often needs to be repainted due to damage, aging or external appearance. Sometimes in order to weld the enameled wire firmly, it is also necessary to remove the paint film on the welding part ...
