Embodiment 1

[0013] A kind of manufacture method that is the adhesive tape of base material with polyimide film, comprises steps and is:

[0014] (1) Grind 40kg of larch arabic galactan gum into granular substances with a pulverizer, add the granular substances into a stirrer filled with 200kg of glycerin, seal and stir to completely dissolve the granular substances, and then add 10kg mastic varnish is mixed thoroughly, obtains colloidal substance, if described colloidal substance is too dilute, glycerine is volatilized to the heating of described colloidal substance;

[0015] (2) Glue the colloidal substance on the polyimide film on a coating machine, and dry the polyimide film naturally to obtain a tape with the polyimide film as the base material.

Embodiment 2

[0017] (1) Grind 8kg of peach gum into granular substances with a pulverizer, add the granular substances to a blender filled with 25kg of glycerin, seal and stir to completely dissolve the granular substances, and then add 1.25kg of mastic varnish Mix thoroughly to obtain a colloidal substance, if the colloidal substance is too thin, heat the colloidal substance to volatilize the glycerin;

[0018] (2) Glue the colloidal substance on the polyimide film on a coating machine, and dry the polyimide film naturally to obtain a tape with the polyimide film as the base material.

Embodiment 3

[0020] (1) Gum tragacanth 20kg is crushed into granular substances with a pulverizer, and the granular substances are added to a blender containing 100kg of glycerin, sealed and stirred to completely dissolve the granular substances, and then add 5kg of mastic varnish Mix thoroughly to obtain a colloidal substance, if the colloidal substance is too thin, heat the colloidal substance to volatilize the glycerin;

[0021] (2) Glue the colloidal substance on the polyimide film on a coating machine, and dry the polyimide film naturally to obtain a tape with the polyimide film as the base material.

[0022] The invention discloses a method for manufacturing an adhesive tape with a polyimide film as the base material. The adhesive tape has great flexibility and elasticity when used, has a long sticking time, and has a high bonding strength, which can reach 9.3 N / m Excellent bonding strength, good bonding effect on materials such as wood, leather, fabric, cardboard and plastic.

Abstract

The invention discloses a manufacturing method of an adhesive tape taking a polyimide film as a base material. The manufacturing method comprises the following steps of: grinding gum into particular substances by a grinder; adding the particular substances into a stirrer containing glycerol; sealing and stirring until the granular substances are completely dissolved; adding frankincense paint and mixing uniformly to obtain a colloid substance; coating the polyimide film with the colloid substance on a coating machine; and naturally drying the polyimide film to obtain an adhesive tape taking the polyimide film as a base material. According to the manufacturing method of an adhesive tape taking a polyimide film as a base material, disclosed by the invention, the adhesive tape has great flexibility and elasticity, long sticking time and high gluing strength when in use, can realize the gluing strength of 9.3N / m, and ensures a perfect gluing effect on the materials such as wood, leather, fabrics, paperboards, plastics and the like.

Description

technical field [0001] The invention relates to a method for manufacturing an adhesive tape, in particular to a method for manufacturing an adhesive tape with a polyimide film as the base material. Background technique [0002] The tape has the characteristics of being easy to bond when using a small pressure, can achieve a bonding effect in a short time, does not pollute the adherend after peeling off, and can be re-corrected when it is wrongly pasted. Some tapes have basically the same adhesive performance after repeated use, and the tape is easy to use. Now the tape partially replaces the traditional mechanical fixation and the use of adhesives, such as the sealing transparent tape used in daily life, electrical tape for wire insulation, etc. With the development of polymer chemistry, the advancement of adhesive technology and processing equipment, tapes have been widely used in packaging, printing, automobiles, home appliances, electronics, medical, aviation, constructi...
