Embodiment 1

[0040] Formula: twisted glass fiber gauze 25%, film 5%, solvent release agent 1%, coating primer 24%, coating surface adhesive 45%;

[0041] Preparation method: PET film with 3% of the total mass of the tape is passed through a coating machine, one side is coated with 1% solvent release agent, and the other side of the film is coated with 24% primer through a coating machine; 25% twisted glass fiber gauze and film are firmly combined, and then coated with 45% surface glue on the twisted glass fiber, and then rewinding and cutting can be started to make twisted glass fiber tape.

[0042] Effect: From the beginning of weaving to the whole process of cutting and packaging, the strand-woven glass fiber tape will not appear like the traditional flat-woven glass fiber tape: yarn shifting, twisting, messy, etc. Instead, the surface of the tape is intuitive and the grid pattern is clear; the process flow is simplified, the production efficiency is improved, and the production cost is ...

Embodiment 2

[0045] Formula: twisted glass fiber gauze 40%, film 6%, solvent release agent 0.5%, coating primer 28%, coating surface adhesive 25.5%;

[0046] Preparation method: PET film with 3% of the total mass of the tape is passed through a coating machine, one side is coated with 0.5% solvent release agent, and the other side of the film is coated with 28% primer through a coating machine; 40% twisted glass fiber gauze and film are firmly combined, and then coated with 25.5% top glue on the twisted glass fiber, and then rewinding and cutting can be started to make twisted glass fiber tape.

Embodiment 3

[0048]Formula: twisted glass fiber gauze 45%, film 3%, solvent release agent 0.6%, coating primer 22%, coating surface glue 29.4%; preparation method: PET film with 3% of the total mass of the tape, by coating Layer machine, one side is coated with 0.6% solvent release agent, and the other side of the film is coated with 22% primer by the coating machine; 45% twisted glass fiber gauze and film are firmly combined by pressing rollers , and then coat 29.4% surface glue on the strand-woven glass fiber, and then you can start rewinding and cutting to make strand-woven glass fiber tape.

[0049] The components used in the present invention are all commercially available products.

Abstract

The invention relates to a twist-woven glass fiber adhesive tape. The twist-woven glass fiber adhesive tape comprises twist-woven glass fiber gauze, wherein the substrate of the twist-woven glass fiber gauze is formed based on the twist-woven structure technology, two warp yarns, a single weft yarn and two glass fiber yarns are adopted, and the glass fiber yarns are independently wrapped with the warp yarns and then twist-woven with the weft yarns to form the twist-woven glass fiber adhesive tape; after being twist-woven, the two warp yarns are combined to firmly wrap and clamp the weft yarn. The twist-woven glass fiber adhesive tape has the following beneficial effects: 1) in the production and manufacturing processes of the adhesive tape, the glass fiber gauze does not move or deform, and thus the appearance of the adhesive tape is beautiful; 2) in the twist-weaving process, the previously separate warp yarns are automatically combined into the double-strand wrap yarn, so that the longitudinal tensile strength is improved by two times, and super strong tensile strength and impact resistance are realized; 3) a solvent parting agent is used for forming the coating, and the cases of falling and color change of a solvent-free parting agent are overcome; 4) the glue is high in perspectivity and high in permanent adhesion; 5) the twist-woven glass fiber adhesive tape has excellent comprehensive properties such as water resistance, insulation, shock resistance, explosion resistance and the like.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to an adhesive tape containing twisted glass fibers. Background technique [0002] The glass fiber tape currently available on the market, its glass fiber gauze structure is the traditional plain weave structure technology, used in the tape, the defect is obvious; the glass fiber yarn itself is very smooth, from the beginning of weaving to the application of the tape, because of flat The generality of the weaving structure is too simple, and a slight external force or friction will cause a large amount of displacement of the yarn, which is messy and seriously affects the surface quality of the tape. It is at a disadvantage in overseas market competition. [0003] In the existing weaving technology, because of the flat-woven glass fiber, the organization form is a single warp thread and a single weft thread, the structure is loose, and the force is single and thin. It is used in adhesiv...
