Embodiment Construction

[0020] The invention provides a device for measuring the fluidity of rubber compound, which comprises:

[0021] The upper mold for pressing down the rubber compound that needs to be tested for fluidity, the lower mold for carrying the rubber compound that needs to be tested for fluidity and the rubber compound that needs to be tested for fluidity, the lower mold has a The groove carrying the rubber compound whose fluidity needs to be tested has a circular hole with a fixed diameter at the bottom of the groove.

[0022] Wherein, the diameter of the circular hole is preferably 1-5 mm.

[0023] Among them, the rubber compound is the rubber after kneading, including natural rubber and various additives, and the compound after these things are fully mixed together is the rubber compound.

[0024] The present invention also provides a method for measuring the fluidity of the rubber compound using the above-mentioned device for measuring the fluidity of the rubber compound, which in...

Abstract

The invention discloses a device for measuring the flowability of a rubber compound. The device comprises an upper die for downwards pressing the rubber compound of which the flowability is required to be tested, a lower die for bearing the rubber compound of which the flowability is required to be tested and the rubber compound of which the flowability is required to be tested, wherein the lower die is provided with a groove for bearing the rubber compound of which the flowability is required to be tested; and a round hole with the fixed diameter is formed in the bottom of the groove. According to the device disclosed by the invention, the flowability of the rubber compound is quantitatively determined, so that the evaluation criteria for the characteristics of the rubber compound are enriched and the characteristics of the rubber compound can be better measured.

Description

technical field [0001] The invention belongs to the technical field of rubber compound testing, in particular to a measuring device for the fluidity of rubber compound. Background technique [0002] In the rubber industry, the fluidity of the rubber material has a direct relationship with the quality of the final product. The lack of fluidity of the rubber material can directly lead to insufficient filling of the rubber material, resulting in under-casting and other similar defects. The existing test method is only to measure the rubber The Mooney viscosity of the compound, it is considered that the filling performance of the AC with the same Mooney viscosity is similar, but in actual production, it is found that the Mooney viscosity does not fully reflect the properties of the rubber compound, especially the flow properties of the rubber compound. The flow properties of rubber compounds with Mooney viscosity are sometimes very different, so the existing rubber compound perf...
