Glue for coating brush and preparation method of glue

Abstract

The invention provides glue for a coating brush. The glue for the coating brush comprises the following components, by weight, including 10-20 parts of polyethylene butyral, 2-5 parts of epoxy resin, 10-20 parts of filler, 10-20 parts of aromatic mixed solvents, 45-58 parts of alcohol mixed solvents and 0.1-0.3 part of antifoaming agents. The aromatic mixed solvents are formed by mixing methylbenzene, dimethylbenzene and trimethylbenzene according to a random proportion. The alcohol mixed solvents are formed by mixing methyl alcohol, ethanol, butanol, isopropanol and isobutanol according to a random proportion. The glue for the coating brush has the remarkable advantages that the solvent resistance capability of the brush is enhanced, so that the service life of the brush is prolonged to at least one month; the drying speed is high, the viscosity is low, the fluidity is good, and the glue is colorless permeable liquid and is weak in smell and environmentally friendly; the glue is low in cost, simple in production process and convenient and fast to use.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a glue for paint brushes. Background technique [0002] Oil-based paints often involve different solvents such as benzene, esters, ketones, alcohols, alkanes, hydrocarbons, etc. The brushes used in the production process are often corroded by various solvents. It is poor, especially for ketone and ester solvents. The brush will start to shed hair in a few minutes when encountering such solvents. At the same time, the fixing collar is easy to fall off. Often, the service life of a brush is only about 1 week. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a kind of glue for paint brushes, which has strong solvent corrosion resistance. [0004] A glue for paint brushes, comprising, by weight components: 10-20 parts of polyvinyl butyral, 2-5 parts of epoxy resin, 10-20 parts of filler...
