Glue with high permanent adhesive force

Abstract

The invention relates to glue with high permanent adhesive force, which is prepared from the following components in percentage by mass: 13-17 percent of natural rubber, 18-22 percent of petroleum rubber SIS, 18-22 percent of petroleum resin, 18-22 percent of naphthenic oil, 18-22 percent of natural terpene resin, 0.5-1.5 percent of antioxidant, and 3.5-4.5 percent of rubber accelerator. The glue has the beneficial effects that packed boxes are difficult to curl and permanent adhesive force is improved to above 100H from below 3H; the glue is difficult to age; the fusing property of molten raw materials is good; the temperature resistance and weather resistance of the glue are stable; and nationalized natural resources are fully utilized, production cost is effectively reduced and market competitiveness of products is improved.

Description

technical field [0001] The invention relates to a technical innovation of tape adhesive materials and formulations, in particular to components of the high-stick-holding glue. Background technique [0002] The so-called high-holding force refers to the tape coated with the high-holding force glue. When in use, the adhesive force between the tape and the surface of the object lasts for a long time, is firm, and is not easy to fall off. It has the following functions and uses. [0003] Function: After the high-holding adhesive glue is applied to the base material with a coating machine, the tape has super-adhesive force, and it can effectively bond with the surface of the object for a long time; it has a remarkable effect in sealing boxes and other bonding, Moreover, the tape has a long service life, is not easy to warp and fall off, and is not easy to delaminate, which ensures the quality of customers' products. [0004] Uses: Tape coated with high-viscosity glue, mainly sui...

AI Technical Summary

Problems solved by technology

[0009] First, the box is easy to warp; when making glue, the main raw materials such as petroleum rubber and petroleum resin are generally used, and the performance is unstable, which seriously affects the balance of the three forces of the glue. The adhesion is poor, and the tape and the object are not easy to stick firmly. After being put on, warping appeared soon, which brought great trouble and inconvenience to customers

[0010] Second, the glue is easy to age; the petroleum rubber and petroleum resin in the existing glue-making materials are easily oxidized when heated and melted, so that they lose their original properties and cause the glue to lose its viscosity

[0011] Third, the fusion is poor; the existing raw materials petroleum rubber and petroleum resin have few varieties and single performance after heating and melting, and cannot complement each other, resulting in one-sided fusion performance of the glue and seriously affecting the quality of the tape.

[0012] Fourth, the cost is high. At present, the oil price in the world is extremely unstable, and it is difficult to predict whether it is high or low, and it is basically operating at a high price. As a result, the price of petroleum products remains high, causing great pressure on the company
