Technical Field
The invention relates to the field of tire testing, in particular to a method for testing the foaming point of a tire sizing material of a passenger car.
Background
As is well known, the foaming points of the rubber materials determined by the current passenger car tire enterprises are detected by using a foaming instrument, and then the vulcanization time of the tire is formulated according to the foaming time provided by the foaming instrument. The foaming time of the rubber materials is detected in batches by using a foaming instrument, and according to practical verification, the time reproducibility of the foaming points detected by the rubber materials with the same type is found to be poor, and the error of the vulcanization time of the tire is established according to the data. Most tire enterprises are in order to ensure the quality safety of the tires, the formulated tire vulcanization time is longer than the actual rubber material foaming point time, and the optimal tire vulcanization time is not calculated according to the actual tire vulcanization foaming point time, so that the tire is over-vulcanized, the production efficiency is reduced, and the energy is wasted.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a method for testing the foaming point of the passenger car tire rubber material, which can truly and effectively detect the foaming time of the rubber material.
The technical scheme adopted for solving the technical problems is as follows: a method for testing foaming point of tyre material of passenger car uses a material sulfur transformer, a tyre thermocouple thermometer and a tyre laser interferometer to measure indexes, and is characterized in that firstly, the material sulfur transformer is used for testing the material used by the same batch of tyre blanks; secondly, vulcanizing tires with different cycle times on the same batch of embryo, and detecting the tires with different vulcanization cycles by using a tire laser interferometer until the vulcanization cycle time from SDS bubbles to non-SDS bubbles of the tire is detected; according to the recorded vulcanization cycle time required by the tire when the SDS bubbles disappear, using a tire thermocouple thermometer to carry out actual vulcanization temperature measurement on the tire blank; calculating the equivalent vulcanization time of the embryo rubber material by utilizing an Arnius equation, comparing the equivalent vulcanization time with the test result of a rubber material sulfur transformer to obtain the time required by the disappearance of the real foaming point of the rubber material, and then formulating the optimal vulcanization time of the tire with the specification according to the time required by the disappearance of the foaming point of the rubber material.
The invention has the advantages that the measuring method is accurate and reliable, the foaming point time of the sizing material can be truly detected, the optimal vulcanization time is formulated, the production efficiency is improved, the energy waste is avoided, and the comprehensive performance of the tire is improved.
Detailed Description
According to the distribution condition of the temperature field of the actual vulcanization of the tire, the large probability of the tire setting vulcanization time of the passenger car is based on the foaming point time of the tread rubber and the triangle rubber core rubber. This example describes tread rubber as an example:
the first step is to use a rubber material thiometer to test a tread rubber material used for the same batch of embryo by using a 150-degree thiometer, and record t10:6.51 min, t15:7.3 minutes, t20:8.0 minutes, t25:8.28 minutes, t30:8.51 min, t35:8.80 minutes, t40:9.17 minutes, t45:9.48 minutes, t50:9.71 minutes;
the second step is to vulcanize the same batch of embryo for seven tires with 10 minutes, 10.5 minutes, 11 minutes, 11.5 minutes, 12 minutes, 12.5 minutes and 13 minutes respectively;
detecting tires with different vulcanization periods by using a tire laser interferometer, wherein the tire with the vulcanization period of 10 minutes is provided with SDS bubbles, the tire with the vulcanization period of 10.5 minutes is provided with SDS bubbles, the tire with the vulcanization period of 11 minutes is provided with SDS bubbles, the tire with the vulcanization period of 11.5 minutes is provided with SDS bubbles, the tire with the vulcanization period of 12 minutes is provided with no SDS bubbles, the tire with the vulcanization period of 12.5 minutes is provided with no SDS bubbles, and the tire with the vulcanization period of 13 minutes is provided with no SDS bubbles;
fourthly, using a tire thermocouple thermometer to carry out vulcanization temperature measurement on the tire blank for 12 minutes, and collecting vulcanization temperature heating data of tire tread rubber;
fifthly, calculating the equivalent 150-degree vulcanization time of the tire tread rubber for 12 minutes to be 8.80 minutes by utilizing an Arnius equation according to vulcanization temperature rising data;
and (3) vulcanizing the sixth-step tire for 12 minutes, wherein the equivalent 150-degree vulcanization time is 8.80 minutes, and comparing the result of the first-step rubber material thiorheometer test to obtain the true foaming point of the rubber material as t35:8.80 minutes;
seventh, the vulcanization time of the tire foaming point of the specification is 12 minutes, and the safety time increased by 10% -20% correspondingly is the optimal vulcanization time of the tire of the specification; if the tread rubber is adopted for tires with other specifications, the thermocouple temperature measurement can be carried out according to the foaming point time t35:8.80 minutes to calculate the optimal cure time for the formulated tire.
