Recycling processing method of core for rubber pipe production

Abstract

The invention relates to a recycling processing method of a core for rubber pipe production. The recycling processing method of the core for rubber pipe production comprises the following steps of S1, taking a scrapped core as an original core, and carrying out surface treatment on the original core; S2, winding a framework line on the surface of the original core after surface treatment to obtain a semi-finished core; S3, coating the outer surface of the semi-finished core with rubber latex; S4, coating the surface of the semi-finished core coated with the rubber latex with an outer rubber layer to obtain a composite core; and S5, vulcanizing the composite core, and conducting cooling to obtain the core. The recycling processing method of the core for rubber pipe production has the effect of reducing the production cost of the rubber pipe.

Description

technical field [0001] The present application relates to the technical field of rubber hose production, in particular to a method for reusing a core used in rubber hose production. Background technique [0002] With the development of industrial production, the application of rubber hose is more and more extensive. The characteristics of rubber hose are physiological inertia, UV resistance, ozone resistance, high and low temperature resistance, high transparency, strong resilience, compression resistance, permanent deformation, oil resistance, stamping resistance, Acid and alkali resistance, wear resistance, flame retardant, voltage resistance, electrical conductivity and other properties, rubber hoses are often used when transporting gases and liquids. The production of rubber hoses usually has a core method and a coreless method. The core method refers to the rubber hose in the core. The coreless method is to form the skeleton layer and the outer rubber layer directly on ...

AI Technical Summary

Problems solved by technology

[0003] When the rubber hose is usually produced by the core method, the core is drawn out for repeated use after the rubber hose is formed. When the core is used for repeated production of the rubber hose for a long time, the surface of the core will be worn and damaged during use, and it will also age. Thermal expansion increases the outer diameter of the core, making the core unusable and requiring a new core for production

[0004] Regarding the related technologies mentioned above, the inventor believes that there are the following defects: the core material generally has excellent heat resistance and peeling performance, and good dimensional stability, so the general cost price is relatively high. When the core is severely worn and aged and cannot be used, When replacing a new core for production, the production cost of the rubber hose is higher
