Abstract

The invention discloses a preparation method of repeatable pasting solid glue. In a normal temperature reaction kettle at 0-40°C, the raw materials used are added in the following proportions by weight: 60-75 parts of polyacrylate compound, 5- 8 parts, 10-15 parts of polyvinylpyrrolidone and 6-8 parts of sodium stearate, stirred for 1 hour and heated up to 78-80°C, kept for 1 hour, and filled at 80°C. The flow process of the invention is simple, and it only needs to accurately weigh the proportion, control the temperature well, and control the reaction time well. In the whole production process, there is no waste, no pollutants, and clean production is maintained. The solid glue prepared by it can be pasted repeatedly, and the office paper or advertising paper coated with glue can be arbitrarily pasted on wallboards, glass, textiles, and office papers, and can be torn, pasted, torn, and pasted again. Reuse more than 30 times without leaving any marks on the adherend.

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...
