Abstract

The invention relates to a high-strength isolating membrane for tire production, which comprises a first plastic layer and a second plastic layer with the same shape and size, wherein the first plastic layer and the second plastic layer are aligned, a reinforcing net is arranged between the first plastic layer and the second plastic layer, the reinforcing net comprises a plurality of first reinforcing strips and a plurality of second reinforcing strips, the first reinforcing strips are arranged in parallel, the second reinforcing strips are arranged in parallel, and the first reinforcing strips and the second reinforcing strips are staggered and perpendicular to each other; the two ends of the first reinforcing strip extend to the two adjacent edges of the second plastic layer respectively, the two ends of the second reinforcing strip also extend to the two adjacent edges of the second plastic layer respectively, and the included angle of an acute angle formed by the intersecting edges of the first reinforcing strip and the second plastic layer is 45 degrees. The isolating membrane provided by the invention has the advantages of high strength and high toughness, and can be prevented from being deformed, wrinkled and even broken in the isolating membrane stripping process, so that the isolating membrane can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of tire production, in particular to a high-strength isolation film for tire production. Background technique [0002] In the production process of all-steel and semi-steel radial tires, it is necessary to roll the isolation film and rubber semi-finished products together to play the role of isolation and preservation. When the rubber semi-finished products are needed, the isolation film on the surface of the rubber semi-finished products is peeled off . However, due to the relatively high viscosity of the rubber semi-finished product and its own high temperature, when the separator is peeled off, the separator will often be stretched, deformed and wrinkled, resulting in the failure of the separator to be used again, which will increase the production cost. , resulting in a waste of resources. Contents of the invention [0003] (1) Solved technical problems [0004] In view of the deficiencies in the pr...
