Abstract

The invention discloses a correction fluid preparation method and belongs to the field of office supplies. The correction fluid preparation method disclosed by the invention comprises the steps: mixing styrene, butyl acrylate, methyl methacrylate and acrylic acid, adding sodium dodecyl sulphate, octyl phenol polyoxyethylene ether, sodium bicarbonate, a polyvinyl alcohol solution and distilled water, pre-emulsifying, warming, adding an initiator and cooling to room temperature to obtain an emulsion; mixing and stirring a titanate coupling agent and acetone, adding isopropyl alcohol, evenly stirring, adding nano zinc oxide, stirring, performing suction filtration to obtain filter cake and drying the filter cake to obtain a dried material; mixing and ball milling the dried material, titaniumdioxide and a surface active agent, mixing and stirring a ball milled material, deionized water and a dispersing agent and ultrasonically dispersing; adding dispersion liquid into water bath, stirring, inflating nitrogen to achieve a protection effect, heating, dropwise adding emulsion and warming and keeping warm to obtain a thermal-insulation emulsion; heating the thermal-insulation emulsion, adding an adhesive, evenly stirring and mixing, then adding glycerol, stirring, cooling to room temperature and filling into a ball milling machine to be ball milled to obtain the correction fluid.

Description

technical field [0001] The invention belongs to the field of office supplies, and in particular relates to a preparation method of a correction fluid. Background technique [0002] Office supplies are auxiliary supplies used by enterprises or individuals in the process of working. The office supplies industry involves a wide range of fields and covers a wide range of categories, including: file and archive supplies, desktop supplies, office equipment, financial supplies, consumables and a series of work-related supplies. Among them, correction fluid, also known as correction fluid, is mainly composed of resin, pigment and solvent, and is a fine chemical product used to correct writing errors in office and writing. When we are writing manuscripts or making drawings, we cannot avoid writing typos and drawing mistakes. If we re-copy, it will take a lot of work and time. The traditional way of correcting mistakes is to use an eraser to remove typos and strokes. This method of...
