Embodiment Construction
[0013] Specific embodiments of the present invention will be described in detail below.
[0014] 1. A composite tape made of fluorine rubber and chlorinated butyl rubber using two cloths and three glues, such as figure 2 As shown, it includes the fluorine rubber layer 3 located in the middle layer, the two sides of the fluorine rubber layer 3 are respectively provided with a base cloth 1, and the base cloth 1 on each side is provided with a chlorinated butyl rubber layer 2.
[0015] 2. Selection of base cloth: the weight of base cloth currently used at home and abroad is 100g / m 2 Left and right, brocade silk is selected for use in this embodiment, and the gram weight per unit area is no more than 50g / m 2 , that is, two layers of brocade silk are used, and the weight is equivalent to the original layer of base cloth. The warp and weft strength is equivalent to the original base fabric. The warp and weft tearing strength, surface density and width of 507 flame-retardant broc...

Abstract
The invention discloses a fluororubber-chlorinated butyl rubber composite rubberized fabric prepared by adopting two layers of cloth and three layers of rubber. The fluororubber-chlorinated butyl rubber composite rubberized fabric comprises a fluororubber layer (3) located at the middle layer, base cloth (1) respectively arranged on two side surfaces of the fluororubber layer (3), and chlorinatedbutyl rubber layers (2) arranged out of the base cloth (1) on each side surface. A preparation method of the fluororubber-chlorinated butyl rubber composite rubberized fabric comprises the following steps: mixing of fluororubber; mixing of chlorinated butyl rubber; preparation of fluororubber cement; preparation of chlorinated butyl rubber cement; single-face gluing of the base cloth; face-to-facecloth lamination of fluororubber surfaces; double-face coating of the chlorinated butyl rubber cement; standing; vulcanization; and the like. According to the invention, the problem of poor bonding between chlorinated butyl rubber and fluororubber is avoided, the forming of toxicity-proof clothing is facilitated, and the performance of the prepared fabric completely reaches tactical and technicalindexes.
Description
technical field [0001] The invention relates to the field of composite adhesive tape preparation, in particular to a composite adhesive tape and method for making fluorine rubber and chlorinated butyl rubber by using two cloths and three glues. Background technique [0002] Heavy-duty chemical protective clothing is protective clothing worn by chemical personnel to protect themselves from chemicals and poisons when they are working with dangerous chemicals, chemical poisons or corrosive substances. Its air tightness and corrosion resistance requirements are very high. High, and the material of chemical protective clothing is the core material of chemical protective clothing, and its performance requirements are: (1), the "liquid-gas" anti-mustard gas is required to be not less than 130min; (2), the protection of 96% of H 2 SO 4 and 30% NaOH for not less than 120 minutes; (3), protection time for toluene, acetone, acetonitrile, chlorine gas is not less than 60 minutes; (4), ...
