Application of aliphatic acid salt solution as rubber page rolling release agent and rubber page rolling method

Abstract

The invention discloses application of an aliphatic acid salt solution as a rubber page rolling release agent and a rubber page rolling method. Found by the researches of the inventors, through enabling a page-rolled rubber sheet to pass through the aliphatic acid salt solution, the surface of the rubber sheet can be uniformly covered with the aliphatic acid salt solution, so that the wound rubber sheet can not be adhered together; by using the aliphatic acid salt solution, particularly the aliphatic acid salt solution with the mass percentage concentration of over 10%, as the rubber page rolling release agent, an unexpected effect is obtained.

Description

technical field

[0001] The invention relates to a cable production process, in particular to a release agent and a process for the production process of rubber sheet rolling. Background technique

[0002] The toughness of the rubber is very good. Since the rubber material in the rubber feeding port must be kept saturated during extrusion in the subsequent process, in order to ensure the convenience of production in the subsequent process, sheet rolling is required. The non-adhesive film helps the subsequent process to feed evenly during use. It is not easy to break and jam during extrusion, and can keep the rubber at the feeding port saturated. The extruded wire is not easy to fluctuate and has a stable outer diameter.

[0003] In order to prevent the rubber from sticking together after rolling, the current rubber rolling process in the wire and cable industry generally uses various complex-composition release agents with lubricating functions. Due to improper selection of r...

Examples

Embodiment Construction

[0016] A rubber rolling method includes rolling and winding, the film after rolling is conveyed and immersed in a fatty acid salt solution, and then rolled.

[0017] The stearate may be stearate or palmitate, or a mixture thereof. There is no special requirement for the type of fatty acid salt.

[0018] As a further improvement of the present invention, in the above production method, the temperature of the fatty acid salt solution does not exceed 80°C, more preferably, the temperature of the fatty acid salt solution is 30-70°C.

[0019] As a further improvement of the present invention, in the above production method, the fatty acid salt solution is an aqueous solution of fatty acid salt.

[0020] As a further improvement of the present invention, in the above production method, in the fatty acid salt solution, the mass percentage concentration of the fatty acid salt is not less than 10%.

[0021] As a further improvement of the present invention, in the above production me...
