Problems solved by technology

[0003] Fluorine rubber composite materials have strong protective properties against gaseous substances, and exhibit strong anti-corrosion performance against organic solvents. However, there have been no reports on the application of fluororubber composite materials in the field of protective clothing in my country. Therefore, the development of a Fluorine rubber composite tape, and its application in the field of chemical protective clothing, will fill the gap in the application of this material in the field of chemical defense clothing in my country, and lay the foundation for the application of fluororubber composite materials in the field of protection in my country

Embodiment 1

[0074] Fluorine rubber composite tape is made of 507 brocade silk as the base material, double-sided coated with flame-retardant chlorinated butyl rubber layer, and the front is coated with fluororubber layer. When preparing, the 507 brocade silk is dipped in chloroprene on both sides. Glue: Stir the flame-retardant chlorinated butyl rubber and 120# gasoline at a mass ratio of 1:1.5 to make a mortar, and then coat the stirred flame-retardant chlorinated butyl rubber on both sides with 507 brocade silk soaked in neoprene on both sides. Butyl rubber: Stir fluorine rubber and ethyl acetate according to the mass ratio of 1:2 to make a glue, and then coat the front side of the tape coated with flame-retardant chlorinated butyl rubber with fluorine rubber glue to make a composite tape; The composite tape is vulcanized once by drum type; the composite tape after the first vulcanization is vulcanized by tank type for the second time to get the finished product

Embodiment 2

[0076] Fluorine rubber composite tape is made of 507 brocade silk as the base material, double-sided coated with flame-retardant chlorinated butyl rubber layer, and the front is coated with fluororubber layer. When preparing, the 507 brocade silk is dipped in chloroprene on both sides. Glue: Stir the flame-retardant chlorinated butyl rubber and 120# gasoline at a mass ratio of 1:1.5 to make a mortar, and then coat the stirred flame-retardant chlorinated butyl rubber on both sides with 507 brocade silk soaked in neoprene on both sides. Butyl rubber glue; mix fluorine rubber and ethyl acetate at a mass ratio of 1:2 to make glue, and then coat the front side of the flame-retardant chlorinated butyl rubber with fluorine rubber glue to make a composite Adhesive tape; the composite adhesive tape is vulcanized once by tank; after the first vulcanization, the composite adhesive tape is vulcanized by tank for the second time to obtain the finished product.

Embodiment 3

[0078] The preparation method of fluororubber composite adhesive tape comprises the following steps:

[0079] (1) Dip 507 brocade silk on both sides with neoprene;

[0080] (2) Stir the flame-retardant chlorinated butyl rubber and 120# gasoline at a mass ratio of 1:1.5 to make a mortar, and then coat the stirred flame-retardant chlorine on both sides of the 507 brocade silk soaked in neoprene on both sides. Chlorinated butyl rubber mortar, wherein the flame retardant system of flame retardant chlorinated butyl rubber is a mixture of antimony trioxide, decabromodiphenylethane, and zinc borate at a ratio of 30:40:30, and the vulcanization system is ZnO, accelerator A mixture of TT and accelerator ZDC in a mass ratio of 8:1.5:1;

[0081] (3) Stir fluororubber and ethyl acetate according to the mass ratio of 1:2 to make a glue, and then coat the front side of the tape coated with flame-retardant chlorinated butyl rubber with fluororubber glue to make a composite tape, of which T...

Abstract

The invention discloses a composite fluororubber adhesive plaster and a preparation method thereof, belonging to the technical field of chemical defense. The composite fluororubber adhesive plaster takes 507 brocade silk as a basic cloth material and takes the basic cloth material of which the two surfaces are coated with an anti-flaming chlorinated butyl adhesive layer respectively as a main body cloth. The front surface of the main body cloth is coated with a fluororubber layer. In the preparation process, both surfaces of the 507 brocade silk are soaked with a chloroprene rubber adhesive; an anti-flaming chlorinated butyl adhesive is stirred with 120# gasoline at a mass ratio of 1 to 1.5 so as to obtain adhesive cement, and the adhesive cement is coated on the both surfaces of the 507 brocade silk; fluororubber is stirred with acetic ether at a mass ratio of 1 to 2 so as to obtain adhesive cement, and the adhesive cement is coated on the front surface of the adhesive plaster; and a finished product is obtained by primary drum or tank type vulcanization and secondary tank type vulcanization. The composite adhesive plaster disclosed by the invention has a stronger protection property to gas matters and a very strong anti-corrosion property to organic solvents, and has the advantages of good physical and mechanical properties, low price, simple preparation method and very high market value.

Description

technical field [0001] The invention belongs to the technical field of chemical defense, and in particular relates to a fluorine rubber composite adhesive tape and a preparation method thereof. Background technique [0002] Fluorine rubber composite material is a kind of adhesive tape composite material with high air tightness, high barrier property, corrosion resistance and permeability, and flame retardant performance. Its excellent comprehensive performance makes it one of the main research materials in the field of chemical protective clothing. [0003] Fluorine rubber composite materials have strong protective properties against gaseous substances, and exhibit strong anti-corrosion performance against organic solvents. However, there have been no reports on the application of fluororubber composite materials in the field of protective clothing in my country. Therefore, the development of a Fluorine rubber composite tape and its application in the field of chemical protec...
