Abstract

The invention provides a tire curing bladder and a preparation technology thereof, and belongs to the technical field of rubber tires. The technology includes two stages, wherein in the first stage, 268 butyl rubber IIR, 1/2 carbon black N330, 1/2 carbon black N330 and other materials except 202 resin are added in sequence; in the second stage, first-stage rubber is added, filtering is carried out, the 202 resin is added, standing is carried out, and curing is carried out. The curing bladder and the preparation technology thereof have the advantages that the materials are scientific and environmentally, the cost is low, the economic benefit is good, and the yield is high. The tire curing bladder and the preparation technology thereof are reasonable in design, the raw materials are easy toobtain, the formula is simple, the safety and reliability are achieved, the technology is convenient to operate and easy to master, and the application and popularization value is good.

Description

technical field [0001] The invention relates to the technical field of rubber tires, in particular to a tire curing bladder and a manufacturing process thereof. Background technique [0002] In general, with the continuous progress and development of science and technology, the manufacture of agricultural tires, motorcycle tires, electric tires, small force tires, etc. is becoming more and more technological, from the labor-intensive type to the technological modernization type. [0003] The tire is called a raw tire when it is formed. When the raw tire is blown up when the rubber and the cord are made of the raw tire, the molding capsule is used (only ordinary air can be passed). When the green tire is vulcanized, that is, after it is put into the mold, there is a bladder inside the green tire that passes high-temperature water vapor, in order to blow up the green tire to make it closely contact with the mold and discharge the air between the green tire and the mold , this...
