Description

Technical Field

[0001] This invention relates to the field of damping materials technology, specifically to a high-damping wide-temperature-range damping material composition, a high-damping wide-temperature-range damping material, its preparation method, and its application. Background Technology

[0002] With the development of modern industry, mechanical equipment is moving towards high speed, high efficiency, and automation. However, the vibrations generated during the operation of mechanical instruments can seriously damage the accuracy, reliability, and stability of the equipment, and the noise generated can also harm people's physical and mental health. Damping materials are functional materials that can absorb vibrational mechanical energy and acoustic energy and convert them into heat energy, electrical energy, magnetic energy, or other forms of energy for dissipation.

[0003] The fundamental principle of damping is energy dissipation. Various damping techniques revolve around converting excited vibrational energy into other forms of energy (such as thermal energy, deformation energy, etc.) to quickly restore the system to its pre-excitation state. There are three main methods of damping: system damping, structural damping, and material damping. Damping materials can be classified into viscoelastic damping materials, high-damping alloy materials, composite damping materials, and intelligent damping materials. Composite damping materials include polymer-based damping composites and metal-based damping composites, while intelligent damping materials mainly include piezoresistive damping materials and electrorheological fluid damping materials.

[0004] With the development of high technology, the requirements for damping materials are becoming increasingly stringent. Whether in traditional military and machinery sectors, or in aerospace, construction, and home appliance industries, there is a growing demand for damping materials with wide temperature ranges, high performance, and intelligent operation. The research and development of damping materials with excellent comprehensive performance has become a research hotspot. High-performance damping materials, as a class of functional materials, will continue to develop towards higher performance, greater intelligence, and greater precision.

[0005] Rubber, due to its unique viscoelastic properties, has always been a primary material for vibration damping and noise reduction. Polyisobutylene-based rubbers, with their densely packed side methyl groups forming a worm-like chain structure and secondary transitions near the glass transition temperature, exhibit a broad and high damping peak, making them a relatively ideal rubber damping material. However, single rubber components often suffer from low damping factors, narrow damping temperature ranges, or effective temperature ranges outside the damping functional region, resulting in poor vibration damping and noise reduction effects and failing to meet the increasingly stringent application requirements in engineering fields, necessitating performance improvements. Techniques such as rubber blending, copolymerization, filler modification, organic small molecule hybrid damping, solution co-precipitation, and IPN (Integrated Particulate Polyacrylonitrile) to improve the damping performance of rubber materials, especially broadening the damping temperature range, have become research hotspots. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of low damping factor, narrow damping temperature range, or effective temperature range outside the damping functional region of existing damping materials, and to provide a high-damping wide-temperature-range damping material composition, a high-damping wide-temperature-range damping material, its preparation method and application.

For numerical ranges, the endpoint values ​​of the various ranges, the endpoint values ​​of the various ranges and individual point values, and individual point values ​​can be combined with each other to obtain one or more new numerical ranges, which should be considered as specifically disclosed herein.

[0021] The first aspect of the present invention provides a high-damping, wide-temperature-range damping material composition, wherein the composition comprises the following components in parts by weight: 100 parts by weight of butyl rubber; 5-40 parts by weight of ultra-high molecular weight polyisobutylene; 5-50 parts by weight of reinforcing agent; 5-40 parts by weight of synthetic resin; 1-5 parts by weight of plasticizer; and 0-10 parts by weight of compatibilizer.

[0022] The viscosity-average molecular weight of the ultra-high molecular weight polyisobutylene is 4 million to 12 million.

[0023] In this invention, the inventors discovered that combining ultra-high molecular weight polyisobutylene (HMPIB) with a specific viscosity-average molecular weight and butyl rubber can significantly improve the damping performance of the butyl rubber composition, resulting in a composition with a high damping factor and a wide damping temperature range, thereby giving the composition excellent vibration reduction and noise reduction effects.

[0024] Furthermore, when the amounts of each substance in the composition meet the above-mentioned range, the resulting composition has an improved damping factor and an improved damping temperature range, thereby giving the composition an excellent vibration reduction and noise reduction effect.

[0025] Furthermore, in order to further improve the vibration reduction and noise reduction effect of the composition, the inventors studied the dosage of each raw material in the composition. The study found that when the composition includes the following components in parts by weight: 100 parts by weight of butyl rubber; 10-30 parts by weight of ultra-high molecular weight polyisobutylene; 20-40 parts by weight of reinforcing agent; 10-30 parts by weight of synthetic resin; 1-3 parts by weight of plasticizer; 5-10 parts by weight of compatibilizer; and the viscosity-average molecular weight of the ultra-high molecular weight polyisobutylene is 6-10 million, the overall performance of the composition is more excellent.

[0026] In this invention, the addition of plasticizers facilitates the full diffusion of reinforcing agent particles, allowing for thorough mixing between the reinforcing agent particles and the polymer, thereby improving processing performance. The addition of antioxidants helps prevent material degradation, cross-linking, oxidation, and other changes in its properties during processing.

[0027] In this invention, adding a compatibilizer to the composition is beneficial to the dispersibility of ultra-high molecular weight polyisobutylene (HMPIB), improves the compatibility between the rubber phase and the resin phase, and thus improves the overall performance of the composition.

[0028] According to the present invention, the viscosity-average molecular weight of the ultra-high molecular weight polyisobutylene is 4 million to 12 million; preferably 6 million to 10 million.

[0029] According to the present invention, the composition further comprises: 1-5 parts by weight of activator; 0.5-3 parts by weight of vulcanizing agent; 0.5-3 parts by weight of vulcanization accelerator; and 0.5-3 parts by weight of antioxidant.

[0030] Furthermore, the composition further includes: 2-4 parts by weight of activator; 1-2 parts by weight of vulcanizing agent; 1-2 parts by weight of vulcanization accelerator; and 1-2 parts by weight of antioxidant.

[0031] According to the present invention, the butyl rubber is ML 100℃ (1+4) The saturation degree is 40-60, preferably 48-54; the unsaturation degree of the butyl rubber is 1.5-2%, preferably 1.6-1.8%.

[0034] According to the present invention, the synthetic resin is selected from at least one of polypropylene, polyethylene and polyvinyl chloride.

[0035] According to the present invention, the compatibilizer is selected from at least one of SBS styrene-butadiene block copolymer (SBS), hydrogenated styrene-butadiene block copolymer (SEBS), and hydrogenated styrene-isoprene block copolymer (SEPS).

[0040] According to the present invention, the vulcanization accelerator is selected from at least one of accelerator TMTD, accelerator TBBS, accelerator CZ, accelerator DM and accelerator M.

[0041] In this invention, the inventors discovered that by using the vulcanizing agent and vulcanization accelerator described in this invention and adding them to the composition in the amounts specified in this invention, the degree of crosslinking and storage modulus of the vulcanized rubber prepared from the composition can be improved, and the damping coefficient can be reduced, so that the composition and the vulcanized rubber prepared from the composition have excellent vibration reduction, noise reduction and fatigue resistance.

[0042] A second aspect of the present invention provides a high-damping wide-temperature-range damping material, wherein the high-damping wide-temperature-range damping material is prepared from the above-mentioned high-damping wide-temperature-range damping material composition.

[0043] In this invention, the high-damping wide-temperature-range damping material exhibits excellent damping performance from low temperatures (e.g., -60°C) to high temperatures (e.g., 60°C).

[0044] Specifically, the high-damping, wide-temperature-range damping material Tanδ max The value is 0.8-1.25; the T of the high-damping wide-temperature-range damping material is... max The damping temperature range is -15℃ to 10℃; when Tanδ≥0.3, the damping temperature range of the high-damping wide-temperature-range damping material is greater than or equal to 94℃; when Tanδ≥0.7, the damping half-width temperature range of the high-damping wide-temperature-range damping material is greater than or equal to 41℃.

[0045] In this invention, Tanδ maxThe larger the value, the wider the damping temperature range, indicating better damping performance of the damping material. The temperature range of Tanδ≥0.3 is used to characterize the damping temperature range of the damping material. The larger the ΔT1 corresponding to Tanδ≥0.3, the wider the damping temperature range of the damping material. The temperature range of Tanδ≥0.7 is called the damping half-width temperature range. The larger the corresponding ΔT2, the better the damping performance of the damping material.
