Abstract

The invention discloses an adhesive for an optical grating label and a preparation method of the adhesive, and relates to the technical field of adhesives. The adhesive is prepared from the followingraw materials in parts by weight. The adhesive is prepared from polyvinyl butyral resin, aldehyde ketone resin, ethanol, n-butyl alcohol, a formaldehyde aqueous solution, melamine and dibutyl phthalate. The preparation method of the adhesive comprises the following steps: weighing quantitative raw materials according to a formula ratio; uniformly mixing a formaldehyde aqueous solution with melamine, then heating, stirring and cooling the mixture to obtain a curing agent; uniformly mixing polyvinyl butyral resin, aldehyde ketone resin, ethanol and n-butyl alcohol until the components are completely dissolved to obtain an adhesive stock solution, and finally slowly mixing the obtained curing agent with the adhesive stock solution to obtain the adhesive. The invention has the advantages of low cost, moderate viscosity, high bonding strength, safety and environmental protection, simple and feasible preparation method, and is beneficial to simplifying the assembly process, improving the signal transmission efficiency and reducing the production cost.
