Abstract

The invention relates to a kind of water-based tippex, which contains following compositions by weight share: 10~20% of bond 1 that is an emulsion contains natural gum, 0.5~14% of the bond 2 that is an emulsion contains organic silicon and aldehyde-ketone resin, 1.5~6.5% of oxidized bleaching, 19.5~51.5% of titanium dioxide, 20~50% of distilled water, 1.5~5% of (as opposed to the total weight) additional functional additives. Its preparation includes following steps: it respectively prepares the colloidal system of bond 1, the colloidal system of bond 2 and the solution of the oxidized bleaching, and then it mixes above materials, the titanium dioxide and the additional functional additives.

Description

technical field [0001] The invention relates to a coating composition, in particular to a water-based correction fluid and a preparation method thereof. Background technique [0002] The solvents of the current traditional correction fluids are organic hydrocarbons. For example, solvent-based correction fluids usually use toluene, chlorofluorocarbons, and cycloalkanes as solvents. Technically speaking, the dissolution effect is ideal, which is conducive to the synthesis of the system, and various properties can meet the use standards, but it has serious problems. The disadvantage is that it emits a strong pungent smell when used, and the gas has certain toxicity, which poses certain hazards to human health and the environment. The reason why it brings unfavorable factors to human beings in use is because it also has potential flammable and explosive dangers, which increases the hidden dangers in production and storage. [0003] People began to carry out the development and...
