Problems solved by technology

[0003] Existing flame-retardant tapes tend to lose their adhesive properties when heated at high temperatures when used, have low structural strength, and have limited flame-retardant properties. If the temperature is too high, they will be ignited, and the effect of completely flame-retardant cannot be achieved.

[0024] The thickness of the insulating layer is 0.05-0.07mm.

[0025] A method for manufacturing an ultra-thin aramid paper flame-retardant adhesive tape, comprising the follo...

Embodiment 2

[0031] The difference with embodiment 1 is:

[0032] The flame retardant layer includes the following components by weight: 20 parts of magnesium hydroxide, 18 parts of acrylate, 2 parts of dispersant, 3 parts of ceramic fiber, 17 parts of aramid fiber, and 3 parts of glass fiber;

[0033] The insulating layer includes the following components by weight: 60 parts of silicone rubber, 10 parts of glass fiber, 10 parts of aluminum hydroxide, and 4 parts of hydroxyl silicone oil.

Embodiment 3

[0035] The difference with embodiment 1 is:

[0036] The flame retardant layer includes the following components by weight: 19 parts of magnesium hydroxide, 19 parts of acrylate, 1.5 parts of dispersant, 4 parts of ceramic fiber, 15 parts of aramid fiber, and 4 parts of glass fiber;

[0037] The insulating layer includes the following components by weight: 55 parts of silicone rubber, 15 parts of glass fiber, 9 parts of aluminum hydroxide, and 5 parts of hydroxyl silicone oil.

[0038] When applying this embodiment, the flame-retardant layer of the ultra-thin aramid paper flame-retardant tape is composed of multiple groups of fibers, which has good flame retardancy and physical strength, and has appropriate flexibility; the adhesive layer and high-temperature-resistant glue have a certain High temperature resistance and strong adhesion, long-term use will not fall off, enhance safety performance; the insulation layer has good heat resistance, can be extinguished immediately af...

Abstract

The invention discloses an ultrathin aramid paper flame-retardant adhesive tape, which comprises aramid paper, an adhesive layer, a flame-retardant layer, an insulating layer and a high-temperature-resistant glue which are sequentially stacked from top to bottom, wherein the flame-retardant layer comprises the following components in parts by weight: 18-20 parts of magnesium hydroxide, 18-20 parts of acrylate, 1-2 parts of a dispersing agent, 3-5 parts of ceramic fibers, 14-17 parts of aramid fibers and 3-5 parts of glass fibers, and the insulating layer comprises the following components in parts by weight: 50-60 parts of silicone rubber, 10-20 parts of glass fibers, 8-10 parts of aluminum hydroxide and 4-6 parts of hydroxyl silicone oil. According to the invention, the adhesive tape with a good flame-retardant effect is formed.

Description

technical field [0001] The invention belongs to the technical field of adhesive tape manufacture, and in particular relates to an ultra-thin aramid paper flame-retardant adhesive tape and a manufacturing method thereof. Background technique [0002] Insulating tape specifically refers to the tape used by electricians to prevent leakage and perform insulation. Also known as insulating tape, it generally consists of a base tape and a pressure-sensitive adhesive layer. The base belt is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc. The adhesive layer is made of rubber plus tackifying resin and other compounding agents, with good viscosity and excellent insulation performance. Insulating tape has good insulation and voltage resistance, flame retardant, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation protection and other characteristics. [0003] Existing flame-retardant adhesive tapes tend ...
