Title:
タイヤ部材の物性予測方法
Document Type and Number:
Japanese Patent JP7331566
Kind Code:
B2
Abstract:
To provide a method for efficiently predicting physical properties of a tire member after vulcanization with high accuracy.SOLUTION: This tire member physical property prediction method has a first step of obtaining a temperature-time curve indicative of a thermal history which a tire member receives in manufacturing a tire, a second step of preparing a test piece made of unvulcanized rubber, a third step of controlling a temperature of this test piece at intervals of at least one second in accordance with the temperature-time curve to obtain a vulcanized test piece, and a fourth step of measuring visco-elasticity of this vulcanized test piece to predict physical properties of the tire member which will be obtained by using the unvulcanized rubber. In the first step of this prediction method, it is preferable that a green tire made of a combination of a plurality of tire members is prepared and a temperature of each of the tire members is measured during application of heat and pressure to this green tire to obtain a temperature-time curve.SELECTED DRAWING: Figure 1
