As a result of large amounts of tests, the low-frequency damping visco-elastic material has good energy consumption and anti-aging performances under an application environment with a frequency of 0.1-10Hz and a temperature of -20 DEG C to 50 DEG C. Loss factor is 0.5-1.0, and a durability life reaches 80 years.
Description
Technical field
The viscoelastic material of a kind of low frequency damping of the present invention is a kind of low-frequency vibrating viscous-elastic material with high power consumption that is applicable in civil engineering structure, high voltage power transmisson system, machinery, vehicle damping (shaking) engineering.
Background technology
Viscoelastic material is high molecular polymer, is a kind of power consumption material of excellent property, and this material not only has viscosity but also have elasticity.When being subject to repeated stress effect generation distortion, the part energy image position can store like that, and another part energy is converted to thermal energy consumption and dissipates.The viscoelastic damper that the viscoelastic material of using is made as core is a kind of effective passive energy dissipation (shaking) control device, and after Abroad in Recent Years is used for structural damping control and shake with it, the repairing and reinforcement engineering is increasing.China has also entered the application primary stage to the research of viscoelastic damper, and viscoelastic damper is as the product of applying in structural damping (shaking) engineering, and it is quite important that its mechanical property and durability performance just seem.
The mechanical property of viscoelastic damper and the ageing-resistant performance viscoelastic material selected with it is closely related.Traditional rubber damping material, dissipation factor is low, does not possess energy-dissipating property, and most of viscoelastic materials of recently developing are generally developed for high-frequency vibration, lack the viscoelastic material of low-frequency vibration.
The isolation mounting that the viscoelastic material of present most domestic is made or vibration-control system only have the characteristics that suppress the medium, high frequency structural response, and for low-frequency response (for 0.1 ~ 10Hz), general viscoelastic material is to accomplish good vibration isolation or effectiveness in vibration suppression, even there will be the phenomenon (this can obviously find out from dynamics of structure dynamicamplification factor curve) that structural response is amplified, therefore, the low-frequency vibration response that how to suppress structure is a difficult point of the art.
By the Viscous Elastic Mechanics theory as can be known, energy dissipation behavior and the vibrational frequency of viscoelastic material are closely related, and under different frequency, the dissipation factor difference of material is very large.At present, the dissipation factor of domestic viscoelastic material when low-frequency vibration be all less than 0.4, and vary with temperature comparatively violently, with the foreign same type viscoelastic material, compares and also have certain gap.
In addition, the endurance quality of domestic viscoelastic material is not fine, and the design life of general building structure is 50 years, and therefore, the ageing-resistant time limit that is used for the viscoelastic material of house shock-absorption engineering is at least 50 years.
And the ageing-resistant performance of at present domestic viscoelastic material all is difficult to reach this requirement.
The present invention, by the comparative analysis of the mechanical property test result of different ingredients (the 112 kinds of formulas) viscoelastic material to multiple main rubber, has optimized the main rubber that is applicable to the low-frequency vibration field---brominated butyl rubber.
Summary of the invention
Technical problem: the viscoelastic material of a kind of low frequency damping of the present invention is a kind of low-frequency vibrating viscous-elastic material with high power consumption that is applicable in civil engineering structure, high voltage power transmisson system, machinery, vehicle damping (shaking) engineering.
Technical scheme: the viscoelastic material of a kind of low frequency damping of the present invention, this viscoelastic material is by main rubber, reinforcement system, vulcanization system, preventing aging system and softening-Plasticising system is mixing to be formed, wherein main rubber is brominated butyl rubber, reinforcement system is high wear-resistant carbon black and 100 orders-200 purpose Graphite Powder 99 mixed system, and vulcanization system is sulfuration resin, zinc oxide, magnesium oxide, stearic acid mixed system; Take 100 parts of the quality of brominated butyl rubber as basic point, the consumption component of above each material is:
This material is 0.1 ~ 10Hz in frequency, and temperature is that under the environment for use of-20 ℃ ~ 50 ℃, dissipation factor is in 0.5 ~ 1.0.
Also can add preventing aging system in this material, preventing aging system is selected rubber antioxidant MBZ and anti-aging agent Naugard445, and take 100 parts of brominated butyl rubber quality as basic point, the consumption component of preventing aging system is:
Antioxidant MB Z 2-4 part,
Anti-aging agent Naugard445 2-4 part.
This material when mixing softening-Plasticising system adopts the mixed system of TOTM (trioctyl trimellitate) and Escorez 2203LC resin,, take 100 parts of brominated butyl rubbers as basic point, soften-the consumption component of Plasticising system is:
TOTM 10-20 part,
Escorez 2203LC resin 15-25 part.
Main rubber of the present invention adopts brominated butyl rubber, reinforcement system adopts high wear-resistant carbon black and 100 orders-200 order Graphite Powder 99 mixed system, when simultaneously, mixing softening-Plasticising system adopts the mixed system of TOTM (trioctyl trimellitate) and Escorez 2203LC resin.
Beneficial effect: the cross-linked rubber of the viscoelastic material of a kind of low frequency damping of the present invention has low-down rebound resilience, shows good damping capacity.Overcome that isoprene-isobutylene rubber and steel plate adhesive property are poor, vulcanization rate is slow and the shortcoming of difficult and other blend rubbers., by increasing the consumption of high wear-resistant carbon black, can significantly improve the viscoelastic material damping capacity.Simultaneously, softening when mixing-Plasticising system adopts the mixed system of TOTM (trioctyl trimellitate) and Escorez 2203LC resin, has further increased the dissipation factor of rubber unvulcanizate, has improved damping capacity.Formula adopts rubber antioxidant MBZ and anti-aging agent Naugard445 as antiaging system, has improved the ageing-resistant performance of this viscoelastic material, simultaneously the disadvantageous effect of its damping capacity also is significantly less than other antiaging systems.Find through test: in frequency, be 0.1 ~ 10Hz, temperature is under the environment for use of-20 ℃ ~ 50 ℃, to have good energy dissipation behavior and anti ageing property, and dissipation factor is in 0.5 ~ 1.0, performance changes slow in the equivalent material of high-frequency vibration in this temperature frequency scope, the weather resistance time limit reaches 80 years.
