Abstract
Provided is rubber for damping vibration transmitted from a suspension system to frames of a vehicle, more particularly, to vibration damping rubber for a vehicle that has improved equal magnification and damping properties as well as excellent hardness, tensile strength and elongation by using silicone-based rubber containing a vinyl group.
Description
The present invention relates to rubber for damping vibration transmitted from a suspension system to frames of a vehicle, more particularly, to vibration damping rubber for a vehicle that improves equal magnification and damping properties by using silicone-based rubber containing a vinyl group.
Vibration damping rubber for a vehicle damps vibration to maintain a comfortable ride in the vehicle and is applied to an engine mount insulator and a bush insulator. The vibration damping rubber for a vehicle for supporting an engine and isolating vibration as main functions is a functional component that is very important and complex. The vibration damping rubber requires static stiffness to support weights of an engine and a transmission and low dynamic stiffness to control transmission of vibration. Also, the vibration damping rubber requires heat-resisting properties to high heat generated in an engine room while a vehicle is moving and durability to repetitive load. Such vibration damping rubber has been progressed development for improving performance and obtaining reliability in order to satisfy customers who demand comfortable ride in a vehicle and improved physical properties.
In the vibration damping rubber, when physical properties such as heat-resisting properties, ageing resistance and durability are improved by mixing of the compositions, vibration insulating properties are deteriorated due to increased equal magnification, particularly due to an increased dynamic spring constant. On the other hand, there is a problem caused by a conflicting characteristic that durability is deteriorated when the equal magnification is improved. It is important to set up a mixing condition of rubber and additive in order to satisfy the conflicting and complex elements.
Since natural rubber has excellent mechanical physical properties and dynamic fatigue resistance, natural rubber has been applied to the vibration damping rubber for a vehicle. However, the natural rubber is not allowed to be used in a temperature of 100 ℃ or more due to development of high-performance vehicle and regulations on exhaust gas. Accordingly, rubbers having an excellent heat-resisting property and ageing resistance such as styrene butadiene rubber (SBR), Polybutadiene rubber (BR), Chroroprene rubber (CR), Nitrile butadiene rubber (NBR), Isobutylene isopropylene rubber (IIR), and Ethylene propylene diene monomer (EPDM) and synthetic rubbers thereof are applied to the vibration damping rubber. However, the physical properties of those rubbers are disappointing.
It is preferable to use silicone rubber since when the silicone rubber is mixed with the above-mentioned rubbers, the silicone rubber shows excellent physical properties such as a heat-resisting property, ageing resistance and durability in comparison with other rubbers. However, since the silicone rubber does not have a double bond in the main chain according to its chemical structure, there is a difficulty in crosslinking of sulfur to cause a problem that durability is deteriorated. Since the silicone rubber has a weak damping property and low mechanical physical properties such as tensile strength, elongation, and hardness, there is a limitation to be used as a material of the vibration damping rubber.
In order to solve the problem of the prior art, provided is a silicone-based vibration damping rubber composition for a vehicle that shows an excellent physical property of silicone rubber and also improves equal magnification and damping properties as a main element of the rubber for damping vibration, and vibration damping rubber for a vehicle that is prepared by using the same.
In order to solve the technical problem, provided is a silicone-based vibration damping rubber composition including 30~60 parts by weight of silica, 1~10 parts by weight of silicone oil having a hydroxyl group at a terminal thereof, and 1~10 parts by weight of organic peroxide based on 100 parts by weight of silicone gum having a structure of Chemical Formula 1 or 2 below.
[Chemical Formula 1]
wherein
R1 represents (C1~C10) alkyl group or (C1~C20) aryl group, and m represents an integer of 1 or greater.
[Chemical Formula 2]
wherein
R2 and R3 independently represent (C1~C10) alkyl group, (C1~C10) fluorinated alkyl group or (C1~C20) aryl group; R4 represents C1~C10) alkyl group or (C1~C20) aryl group; n and r represents an integer of 1 or greater.
In R1, R2, R3 and R4 of Chemical Formulas 1 and 2, as specific examples of (C1~C10) alkyl group or (C1~C20) aryl group, the alkyl group includes methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, 2-methylbutyl, pentyl, iso-amyl, hexyl, cyclohexyl, 3-methylpentyl, and octyl; and the aryl group includes penyl, p-tolyl, 4-methoxypenyl, 4-(tert-buthoxy) penyl, 3-methyl-4-methoxypenyl, 4-fluoropenyl, 4-chloropenyl, 3-nitropenyl, 3-aminopenyl, 3-acetamidopenyl, and 4-acetamidopenyl; and the m, n and r represent an integer of 1 or greater, preferably an integer of 10~3000.
The silicone gum contains a vinyl group of 0.008~0.750mmol/g. The fact that the silicone gum contains the vinyl group, which is related to a curing reaction, is an important factor for improving a mechanical physical property of heat-resistance and durability. When the silicone gum contains a vinyl group of below 0.008mmol/g, the curing reaction is not sufficiently performed and it is difficult to expect the improvement of the physical property. When the silicone gum contains a vinyl group of over 0.750mmol/g, crossinking density increases in curing to raise a cure value. Accordingly, brittle occurs to deteriorate the physical property of rubber.
The silica functions as a filler but other materials also may be used as a filler. The silica may be used in order to allow reinforcement, heat-resisting properties, and incombustibility. A BET specific surface area may be 120~160m2/g and precipitated silica having a particle size of 10~15nm may be used. When the silica within the above range is used, dynamic characteristics, heat-resisting property and durability, which are required for vibration damping rubber after curing, are obtained.
30~60 parts by weight of silica based on 100 parts by weight of silicone gum may be used. More preferably, 40~55 parts by weight of silica may be used. When the content of the silica is below 30 parts by weight, the silica does not function as a filler. When the content of the silica is over 60 parts by weight, the rubber is not proper to be used for damping vibration since strength of the rubber excesses the optimum level due to increase of crosslinking density.
Silicone oil having a hydroxyl group at its terminal may be used at an amount of 1~10 parts by weight based on 100 parts by weight of silicone gum. When the amount of silicon oil excesses the above range, the degree of crosslinking decreases.
The organic peroxide is any one selected from the group consisting of 2,5-dimethyl-2,5-di-(t-butyl peroxy)-hexane, di-t-butyl peroxide, 5-butylcumyl peroxide, α,α′-bis(t-butyl peroxy)diisopropyl benzene, t-butyl perbenzoate and 2,5-di(t-butyl peroxy)hexyne-3. Organic peroxide may be used at an amount of 1~10 parts by weight based on 100 parts by weight of silicone gum. When the content is out of the above range, there is a problem in curing to deteriorate the degree of crosslinking.
Also, the vibration damping rubber composition may further include diverse additives such as antioxidants, retarders, and releasing agents according to usages thereof.
Provided is the vibration damping rubber for a vehicle that is prepared by curing the above-mentioned silicone-based vibration damping rubber composition. Equal magnification of the vibration damping rubber may be 1.6~2.0.
As described above, a silicone-based vibration damping rubber composition for a vehicle according to the present invention has excellent mechanical physical properties such as tensile strength, elongation, and hardness of silicone rubber. In addition, a damping property, which is proper to vibration damping rubber for a vehicle, i.e., equal magnification, is controlled to a range of 1.6~2.0. A damping property (tanδ) is also improved to a range of 0.10~0.13. In particular, the silicone-based vibration damping rubber composition shows remarkably improved heat-resisting properties, ageing resistance and durability in comparison with other conventional rubbers.
