Description
Technical Field
The invention relates to the technical field of damping materials, in particular to a wide-temperature-range high-damping composite rubber material and a preparation method thereof.
Background
With the continuous development of the vibration isolation technology, the laminated rubber support is widely applied in structural engineering and mainly comprises a natural rubber support, a lead rubber support, a high-damping rubber support and the like. The natural rubber support has lower damping of only 0.02-0.04, poorer damping performance and needs matching of a viscoelastic damper and the like when in use. The damping ratio of the lead rubber support can reach 0.12-0.15, but heavy metal pollution is easy to generate in the production process, the current civil construction guidance concept of environment-friendly and green development is not met, and in the use process, the lead in the support is easy to deform and damage due to shearing fatigue (experiments show that the damping performance of the lead is reduced by 25 percent after 5000 times of small deformations). Unlike the former two, the high damping rubber support has better damping performance, the damping ratio is about 0.12-0.20, no pollution and low energy consumption are caused, but the effective unification of high damping and low modulus is difficult to achieve.
Under normal conditions, the damping performance of the halogenated butyl material is superior to that of other materials, but the damping factor is smaller at normal temperature, the effective damping temperature range of tan delta is more than or equal to 0.4 is only between minus 52 ℃ and 15 ℃, the damping is lower, the bonding performance is poorer, and the use requirement of the high damping rubber support cannot be effectively met. The traditional carbon black filler also has high energy consumption, high pollution and other environmental hazards, so that the traditional halogenated butyl material is used as the raw material of the high-damping rubber support and is greatly controversial and objectionable in the use process.
Therefore, how to overcome the defects and drawbacks, providing a composite rubber material with wide temperature range and high damping becomes a technical problem to be solved in the field.
Disclosure of Invention
First, the present invention provides a composite rubber material comprising: raw rubber and a damping agent in a weight ratio of 2.5-5:1;
the raw rubber consists of butyl rubber, polynorbornene rubber and ethylene propylene diene monomer rubber;
the ethylene propylene diene monomer rubber accounts for 8-20% of the raw rubber by weight;
The damping agent is at least one of terpene resin or modified terpene resin.
The invention discovers that the raw rubber composed of butyl rubber, polynorbornene rubber and ethylene propylene diene monomer rubber can enable the damping peak value (loss factor peak value) to move right under the composite rubber material system, effectively improves the damping performance of the rubber material at normal temperature and high temperature, and further widens the effective damping temperature range of the rubber material.
Moreover, the glass transition temperatures of the raw rubber and the damping agent are greatly different, and when the raw rubber and the damping agent in the proportion are adopted, the integral damping factor of the composite rubber material can be obviously improved, and the effective damping temperature range of the low-temperature section and the high-temperature section of the rubber material is effectively widened. Meanwhile, under the condition of raw rubber and the damping agent in the proportion, the wettability of the rubber material and the metal material can be obviously improved, so that the damping agent can form a hydrogen bond effect with rubber and an adhesive (the adhesive is coated on the surface of the metal when the rubber is bonded with the metal), the bonding performance of the rubber material and the metal can be further improved on the premise of ensuring the high damping performance of the rubber material, and the bonding strength of the rubber material and the metal can be improved by more than 60%.

The raw rubber formed under the proportion can be better matched with the damping agent in a synergistic way, so that the mechanical property and damping property of the composite rubber material are further improved, and the damping temperature range is remarkably widened. Experiments prove that the peak value of the first loss factor of the composite rubber material at 0 ℃ can reach more than 1.5, the peak value of the second loss factor at 50 ℃ can reach more than 0.9, and the effective damping temperature range with tan delta more than or equal to 0.4 is widened to-70 ℃ to 70 ℃.
