Abstract

The invention discloses damping rubber with low cost and high damping performance and a manufacturing method thereof. The damping rubber comprises the following components: by weight, 19-30 parts of natural rubber, 8-20 parts of butadiene rubber, 1.8-10 parts of plastics, 19.5-26 parts of carbon black, 2-15 parts of damping agent HC-1 and 1-1.6 parts of vulcanization system. The natural rubber and butadiene rubber are mixed together to improve the relative stability of mechanical property in the repeated stress process of the rubber; the plastics with the temperature much different from the glass-transition temperature of the rubber is added, so that the range of the effective damping temperature of a final product is widened; the damping agent HC-1 is adopted to replace expensive small organic molecules, and the improvement on the damping performance of the rubber is roughly the same under the condition that the adding ratio is basically identical. The cost of the damping rubber formed by adopting the damping agent HC-1 is more than two times that of the damping rubber formed by adopting the small organic molecules.

Description

technical field

[0001] The invention belongs to the field of functional polymers, and in particular relates to a low-cost, high-damping damping rubber and a preparation method thereof. Background technique

[0002] Since the 1960s, shock isolation and energy consumption shock absorption technology has gradually attracted the attention of countries all over the world and has been widely used in building structures and bridge structures. Since the "5.12" Wenchuan Earthquake in our country, building, bridge shock absorption, and shock isolation technology have gradually received attention. Due to its excellent performance, low cost, and no pollution, high-damping rubber bearings have gradually gained attention in domestic bridge design. The method of improving the damping performance of rubber has been researched for more than 20 years at home and abroad. At present, the more mainstream methods mainly include:

[0003] ①Rubber and rubber blending

[0004] The glass transiti...
