Abstract

The invention relates to a preparation method of a novel composite solid gum. The preparation method comprises the following steps: mixing a filling material, ethylene glycol monobutyl ether, and silica sol for one hour to obtain a mixture; then adding sodium metaborate, a dispersant, and succinic anhydride into the mixture in sequence, stirring for 0.5 hour, then adding epoxy resin prepolymer, stirring for 3 hours at a temperature of 140 DEG C; finally adding polyvinylpyrrolidone and zinc chloride hydrate, stirring for 8 hours at a temperature of 60 DEG C to obtain a compound; then filling the compound into a mould, and cold-pressing the compound to obtain the composite solid gum. The disclosed preparation method has the advantages that the raw material resources are wide, the preparation process is simple and controllable, only normal operation is needed, and the preparation method can be easily applied to industrialization.

Description

technical field [0001] The invention belongs to the technical field of preparation of novel composite materials, and in particular relates to a method for preparing novel composite solid glue. Background technique [0002] Most of the currently commercially available glue sticks use PVA and PVP as adhesives, which have low production costs and the performance of solid glue sticks, and have good market competitiveness in adhesion, moisture retention, shaping, and coating. However, according to the QB / T2857-2007 test, the commercially available solid glue sticks still generally have defects such as high colloidal viscosity, coating properties, poor wiping performance, poor moisture retention, and excessive free formaldehyde content, let alone high temperature resistance indicators. [0003] In order to further improve the product quality, reduce the sales price and meet the market demand, many experts and technicians have made a glue stick with good viscosity, smooth and delic...
