Abstract

The present invention discloses preparation process of solid glue capable of adhering repetitively. The solid glue is prepared with polyacrylate 60-75 weight portions, polyglycol 5-8 weight portions, periston 10-15 weight portions and sodium stearate 6-8 weight portions, and through mixing, heating to 78-80 deg.c, maintaining to reaction for 1 hr, and packing at 80 deg.c. The preparation process is simple and clean, and the solid glue is coated to paper for adhering repetitively.

Description

technical field [0001] The invention relates to a preparation method of a repeatable pasting solid glue. Background technique [0002] The development of solid glue can be divided into the following stages: [0003] The first stage: the first invented solid glue is low-quality PVA, the solid glue is relatively soft, and it will fall off in pieces when applied, and the viscosity is not very high, but the cost is relatively low. This kind of solid glue is currently on the market. More, customer feedback is relatively poor. [0004] The second stage: PVP solid glue, the solid glue is hard, easy to apply, good viscosity, and saves the amount of glue. [0005] The third stage: High-viscosity self-fading solid glue. The solid glue has various colors and good hardness. It only needs a little glue on the paper to stick it firmly, and the sticking time is within 15 seconds. The solid glue is applied on the paper. The color disappears completely within 40 seconds of being on the pa...
