[0029] The embodiment can be applied to hot-pressing in the production process of long-fiber siliceous composite nanometer adhesive tape (long-fiber siliceous composite nanometer adhesive tape), and is mainly used in the adhesive link. After the long-fiber siliceous nanometer material is preliminarily mixed with glue or other adhesives, hot-pressing is needed to promote the activity of the adhesives, so that the adhesives can fully infiltrate the long-fiber siliceous nanometer material and enhance the adhesive strength between the fibers.

[0030] The long-fiber siliceous composite nanometer adhesive tape is composed of polyolefin and its derivatives, rubber elastomers, long-fiber polyester and other fibers, and raw materials such as siliceous anti-aging materials, carbon black, nanometer materials and weather-resistant epoxy reinforced glue.

By adding long fibers, the requirements of engineering strength, deformation and resistance to external force are met, and overall structural strength is obtained; by compounding nano-siliceous material, the glue bonding force on the surface of soil body is further improved, and engineering durability is obtained.

[0034] The preparation process of long fiber silicon composite nano glue cloth is as follows:

[0035] 1. Prepare high-performance load-bearing matrix (middle net structure);

[0036] 2. Surface structure nano strengthening:

[0037] 3. Roll forming of glue cloth and reinforced matrix:

[0038] 4. Compound surface structure anti-ultraviolet aging coating:

[0039] The surface structure anti-ultraviolet aging can be generally realized by one of the following processes.

[0040] 1) Add additives, and add anti-ultraviolet aging agents (such as light shielding agents, antioxidants, anti-UV agents, light stabilizers, etc.) to inhibit aging;

[0041] 2) Chemical modification, increase or change some groups in the macromolecular chain of PTFF by using chemical methods, so as to increase the anti-ultraviolet performance, such as solution, suspension grafting process, etc.

[0042] 3) Finishing, including coating finishing, dipping anti-ultraviolet finishing agent, salt and alkali resistance, etc., at present, nano additives are used as anti-aging salt and alkali resistant coating.

In the hot pressing process, the temperature of the hot pressing plate 4 is detected by the temperature detector 6, when the temperature is too high, the cooling pump 45 can be started, the external air is pumped into the cooling pipeline 42 through the cooling pump 45, the hot pressing plate 4 is cooled and cooled, the hot pressing temperature is quickly adjusted, and the influence of overheating on the hot pressing effect is avoided.
