The invention relates to a flame resistant acid and alkali resistant tape and a manufacturing method thereof, and particularly relates to a flame resistant acid and alkali resistant tape made by using a mixed rubber material and a flame resistant agent, and a manufacturing method thereof.

Polymer materials have been widely used in people's livelihood, national defense and industry for a long time. It is closely related to it in daily life, but polymer has a fatal weakness, which is flammable or flammable, so flame retardant technology has become an important issue. .

Materials that are generally prone to fire, such as fabrics such as curtains, tablecloths, tapes, or clothing, usually contain some flame retardant in these fabrics to reduce the chance of fire.

In addition, industrial protection is still an important issue in the chemical protection, and acid and alkali solutions account for a large proportion of the synthesis of raw materials. Users often contact this chemical raw material, but most of the commercially available protective clothing For the material of the cloth, the durability is limited, and the protective effect is not effective. If it can be replaced with a non-woven material, it will improve the chemical protection effect and increase the durability.

However, most of these special clothing products do not take into account the user's comfort, and the weight of such special clothing products is extremely heavy, and the user is not only inconvenient to move but also consumes physical strength after wearing. Moreover, such clothing does not have the characteristics of flame resistance and is generally not scratch resistant.

In view of this, the inventors have based on years of experience in the manufacturing development and design of related products, and after detailed design and careful evaluation of the above objectives, Finally, a practical invention is obtained.

The main object of the present invention is to provide a rubber sheet which is resistant to fire and acid and alkali and a manufacturing method thereof, and helps to improve the protective effect of the protective clothing.

According to a specific embodiment of the present invention, the method for manufacturing a flame resistant acid-base resistant tape comprises the steps of: firstly, providing a base fabric; then, forming a paste layer on opposite surfaces of the base fabric; subsequently, a flame resistant acid-base mixed rubber is adhered to the W paste layer; finally, a vulcanization treatment is performed, wherein the flame resistant acid-base mixed rubber material comprises a neoprene rubber, an ethylene propylene rubber, an inorganic flame resistant filler, and Inorganic filler.

According to the above manufacturing method, the flame resistant acid-base resistant tape comprises a base cloth, a W paste layer and a flame resistant acid-base mixed rubber. Wherein, the W paste layer is disposed on opposite surfaces of the base fabric, and the flame resistant acid-base mixed rubber material comprises a neoprene rubber, an ethylene propylene rubber, an inorganic flame resistant filler and an inorganic filler, and the flame resistant acid resistant A mixed base of alkali is disposed on the W paste layer.

According to the above, the flame-resistant acid-base resistant tape of the present invention can achieve better flame resistance by adding a moderate inorganic flame-resistant filler and an inorganic filler. Furthermore, the flame resistant acid-base mixed rubber is selected from the group consisting of neoprene rubber and ethylene propylene rubber as the main rubber seed, so the flame resistant acid and alkali resistant tape has better chemical resistance. In addition, the double-sided fabric of the base fabric is a flame-resistant acid-base mixed rubber, and the thickness is only about 0.3 mm, so that the finished garment has the above advantages, is more portable, and does not cause a burden on the user.

Blended yarn weaving of fibers.

Next, step S14 is performed to form a W paste layer 20 on the surface of the base fabric 10. Specifically, the base fabric 10 is first fed to the impregnation machine paste on the opposite surfaces of the base fabric 10. Since the paste layer 20 is a paste prepared by dissolving the neoprene rubber in toluene, the surface is required to be The base fabric 10 on which the W paste layer 20 is formed is placed in an oven, and baked at a temperature between 150 and 160 degrees Celsius for a period of time between 90 and 160 seconds to make the W paste layer 20 The solvent is completely volatilized.

In this embodiment, the composition of the W paste layer 20 comprises 80 to 100 parts by weight (PHR) of chloroprene rubber, 5 to 16 parts by weight of a promoter, and 3 to 10 parts by weight of hardening. In addition, the PHR unit represents a percentage of the additive per hundred parts of the rubber content, for example, 20 PHR means that 20 g or kg of the additive is added per 100 g or kg of the rubber.

Subsequently, step S16 is performed to bond a flame resistant acid-base mixed rubber 30 to the W paste layer 20. Specifically, the composition of the flame resistant acid-base mixed rubber 30 comprises 40 to 60 parts by weight of chloroprene rubber, 20 to 40 parts by weight of ethylene propylene rubber, 100 to 200 parts by weight of inorganic flame resistant filler, and 50 to 100 parts by weight of the inorganic filler, the inorganic filler is aluminum hydroxide or antimony trioxide.

In addition, the flame-resistant acid-base mixed rubber 30 is first mixed by a 10,000-horsepower mixer, and then at a temperature between 50 and 95 degrees Celsius with two rollers (one coarse wheel and one thin wheel). The mixing is then carried out by feeding the belt to a calendering laminator to a fixed thickness, wherein the fixed thickness is between 0.1 and 2.0 cm. Moreover, when the mixed anti-acid-base mixed rubber 30 having a fixed thickness is double-sidedly bonded to the base fabric 10, the temperature of the over-gluing machine wheel is controlled to be between 60 and 95 degrees Celsius.

Finally, in step S18, the unvulcanized base fabric 10 to which the flame resistant acid-base mixed rubber 30 is adhered is placed in a tank sulfurizing oven at a temperature between 140 and 150 degrees Celsius. Heating is carried out between 60 and 90 minutes to complete the vulcanization process and winding up, and finally the appearance of the inspection machine is the finished product. The Vulcanization procedure refers to the process of producing a vulcanizate with a three-dimensional network structure by intermolecular crosslinking of a rubber compound, which enables the rubber compound to have high strength, high elasticity, high wear resistance, corrosion resistance and the like.

According to the above manufacturing method, the present invention further provides a flame resistant acid and alkali resistant adhesive tape 1, which comprises a base fabric 10, a W paste layer 20 and a flame resistant acid and alkali resistant mixed rubber material 30.
