Embodiment Construction

[0013] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] In the embodiment of the present invention, a tire vulcanization bladder preparation process adopts the following process steps, and the component ratio is calculated in parts by weight: (1) 98 parts of butyl rubber, 4.96 parts of zinc oxide, 0.9996 parts of stearic acid, alkane 7.35 parts of base phenol formaldehyde resin, 44.1 parts of N220 carbon black, 29.4 parts of N550 carbon black, 4.96 parts of castor oil and 0.735 parts of stannous chloride are poured into a banbury mixer for banburying. The banburying time is 15 minu...

Abstract

The invention discloses a preparation method for a tyre curing bladder. The preparation method comprises the following steps: preparing an internally-mixed rubber material; placing the internally-mixed rubber material into an open mill, carrying out mixing at a mixing temperature of 80 DEG C for 25 minutes, and carrying out discharging from the open mill so as to obtain a rubber sheet with a thickness of 10 mm and a width of 50 mm; naturally cooling the rubber sheet to a room temperature; filling the rubber sheet into the screw of an injection press, wherein the temperature of the screw is 70DEG C; extruding the rubber sheet through the screw, carrying out weighing with a metering pump, and allowing the extruded rubber sheet into a mold cavity, wherein the pressure of the screw is 12 MPa;maintaining the pressure of 12 MPa, and carrying out injection curing; and after completion of curing, ejecting a bladder out of the mold cavity through the injection press so as to obtain the tyre curing bladder. The preparation method provided by the invention has the following advantages: the use times of the tyre curing bladder can be increased; the service life of the bladder is prolonged; significant effects on improvement of high tyre quality are achieved; and by adoption of a staged pressurized vulcanization method, the hardness and extensibility of the curing bladder are improved.

Description

technical field [0001] The invention relates to a preparation process of a tire curing bladder. Background technique [0002] Tires are one of the important parts of the car. They are in direct contact with the road surface, and work together with the car suspension to ease the impact of the car while driving, ensuring that the car has good seating comfort and smooth driving; ensuring that the wheels and the road are in good condition The adhesion of the tire improves the traction, braking and passability of the car; bearing the weight of the car, the important role played by the tire on the car has attracted more and more attention. [0003] The working temperature of the tire curing bladder is generally 180-200°C, and the medium in contact with it is mainly superheated water, superheated steam, compressed air or nitrogen, and the expansion ratio of the tire curing bladder is very large. If the high temperature resistance does not meet the requirements, it will directly lea...
