Abstract

The invention mainly provides a paint remover comprising attapulgite, and a preparation method thereof. According to the invention, benzyl alcohol is adopted as a main component, and is mixed with water, attapulgite, starch, a surfactant and thickening agents. The paint remover comprises 20-35% of benzyl alcohol, 20-30% of water, 1-3% of the surfacant, 35-45% of attapulgite, 3-5% of starch, 2-3.5% of carboxypropylmethyl cellulose, and 2-3.5% of carboxymethyl cellulose. The paint remover is a non-fluid viscous paste-like material. The pH of the peelable paste-like material is neutral. The paint remover does not contain volatile organic compound, and does not pollute the environment. The paint remover can be used for removing surface paint of buildings, home appliances and industrial coatings.

Description

Technical field: [0001] The research content of the present invention is mainly to provide a paint remover containing attapulgite and a preparation method thereof, belonging to the technical field of paint removers. [0002] The present invention mainly provides a kind of benzyl alcohol as main component, mixes with water, attapulgite, starch, surfactant and thickening agent, forms a kind of sticky paste that does not flow, and the pH of the paste can be peeled off. The value is neutral, does not contain volatile organic compounds, and has no pollution to the environment. It can be used to remove paint from the surface of buildings, household appliances and industrial coatings. Background technique: [0003] Attapulgite is a layer chain structure of water-containing magnesium-aluminosilicate clay minerals. Its crystals are called needle-like and fibrous aggregates. The diameter of a single fiber crystal is about 20nm, and the length can reach several um. A natural first-cla...
