Problems solved by technology

[0002] Fluororubber materials are flame-retardant, corrosion-resistant, and high-temperature-resistant, and are often used in the field of chemical protection. However, due to their excellent chemical stability, fluororubber is difficult to combine with other substances. The peeling fastness is low, and the problems of delamination and blistering of protective materials are prone to occur

Abstract

The invention discloses a fluoro-rubber adhesive tape and a manufacturing method thereof. The fluoro-rubber adhesive tape comprises a basic fabric and a rubber layer. The basic fabric is a grid fabric, rubber is arranged on two sides of the grid fabric and are fit through fabric mesh holes. The manufacturing method comprises the steps that the fluoro-rubber is plastified and mixed according to a formula, and mixed rubber having good processing properties is formed by adopting a thin-passing process for aiding; the mixed rubber is prepared into the continuous adhesive tape with the thickness of 0.15-0.20 mm through a calendaring process; the grid fabric is arranged between the two adhesive tapes for sulfur bulging, so that the purpose of fitting and vulcanizing the calendared rubber adhesive tape and the grid fabric is achieved, the vulcanizing temperature is 150-180 DEG C, and the time is 6-15 minutes. The fluoro-rubber adhesive tape produced by adopting the manufacturing method is retardant to flame, high in stripping firmness, resistant to high temperature and corrosion from acid, alkali, a strong oxidant, benzene and other organic solvents.

Example Embodiment

[0018] Example 1

[0019] Plasticizing and mixing 100 parts of fluororubber, 10 parts of magnesium hydroxide, 15 parts of calcium hydroxide, 3 parts of antioxidant, 5 parts of vulcanizing agent, and 30 parts of titanium dioxide to form a rubber compound;

[0020] Calendering the mixed rubber to prepare a continuous tape with a thickness of 0.15mm, the calendering temperature is 80°C, and the speed is 20m/min;

[0021] The mesh fabric is placed between two layers of rubber cloth, and drum vulcanization is performed at a temperature of 170° C. for 10 minutes, so that the calendered rubber cloth and the mesh fabric are vulcanized and bonded to form a fluororubber rubber cloth.

[0022] The fluororubber tape prepared by the above method has a thickness of 0.40mm and a weight of 550g/m 2. The peeling fastness to the base fabric is 0.81N/m, the limiting oxygen index is 29, the breaking strength can reach 350N/5cm, it is resistant to 98% sulfuric acid, 40% sodium hydroxide, 61% nitric acid, does not penetrate for 120 minutes, and has a good appearance. Can be used to make heavy chemical protective clothing.

Example Embodiment

[0023] Example 2

[0024] 100 parts of fluororubber, 15 parts of calcium hydroxide, 2 parts of antioxidant, 6 parts of vulcanizing agent, and 20 parts of titanium dioxide are masticated and kneaded to form a rubber compound.

[0025] The rubber compound was calendered into a continuous rubber cloth with a thickness of 0.18mm by calendering, the calendering temperature was 80°C, and the speed was 20m/min.

[0026] Vulcanization bonding: Put the aramid mesh fabric between the two layers of fluoroelastomer tape, and vulcanize in the drum. The three layers of materials are all slightly tensioned to ensure the flatness when entering the vulcanizing equipment. The vulcanization temperature is 180°C, and the guaranteed vulcanization time is 10 minutes.

[0027] The thickness of the fluororubber tape made in this embodiment is 0.45mm, the limiting oxygen index is 36.4, the breaking strength can reach 500N/5cm, it is resistant to 98% concentrated sulfuric acid, 40% sodium hydroxide, 60% nitric acid, and does not penetrate for 200 minutes. Good appearance.
