Description
Technical Field
The invention relates to the technical field of damping materials, in particular to an environment-friendly damping rubber plate and a preparation method thereof.
Background
In recent years, with the development of modern science and technology, the requirements of people on working and living environments are higher and higher, and vibration and noise control is increasingly becoming a problem to be solved urgently. The viscoelastic damping material has high damping property, can play a role in inhibiting vibration and noise in a relatively wide frequency band, and can be applied to vibration reduction and noise reduction of mechanical components such as automobiles, ships, locomotives and the like.
The damping rubber plate is a common viscoelastic damping material, and is usually adhered to the inner surface of a vehicle body bottom plate in the production process of an automobile, so that the damping rubber plate plays roles in shock resistance, sound insulation and heat insulation. However, most damping rubber plates in the prior art are solvent-based products, such as asphalt is used as a main material, and some damping rubber plates are prepared by directly adding crude oil in order to increase flexibility. Asphalt and crude oil contain a large amount of benzene, polyphenyl and other heterocyclic toxicants which have toxicity, and if the substances are contacted with human bodies for a long time, the substances have great harm to the human bodies. In addition, the traditional damping rubber plate also has the defects of large specific gravity and unobvious shock absorption effect.
The environment-friendly damping rubber plate is also available on the market, such as an acrylate modified damping rubber plate, wherein an acrylate modifier and alkyd resin are heated and uniformly stirred in a reaction kettle, calcium carbonate and short fibers are added, and finally the mixture is formed by a calender, but the damping rubber plate has a small loss factor and cannot meet the requirements of vibration reduction and noise reduction in the current market.
The Chinese invention patent CN200410011306.3 discloses a composite damping rubber plate consisting of a binding layer, a viscoelastic layer and a damping layer, which is a thermosetting damping rubber plate, and is added with various fillers and rubber additives such as vulcanizing agents and the like for damping and reducing noise of automobiles. However, non-environmentally friendly rubber cross-linking agents and accelerators such as tetramethyl thiuram disulfide, diphenyl guanidine, N-cyclohexyl-2 benzothiazole sulfenamide, etc. are used in the material. Easily cause the pollution in environment and the carriage, some cross-linking agents and the VOC who touches into agent industrial chemicals are unqualified in this patent for the composite damping material feature of environmental protection is poor, and the VOC discharges beyond the norm, along with the improvement of car to the environmental protection requirement, the unqualified composite damping material of VOC can no longer be used to the automobile factory. Meanwhile, the crosslinking agent and the trigger agent are added into the rubber, so that the product has poor stability and short storage life, particularly in summer.
Chinese patent CN201310322079.5 discloses a damping rubber sheet, which comprises the following main components by weight: 15-40 parts of nitrile rubber, 10-30 parts of PVC, 15-45 parts of mica powder, 5-25 parts of graphite powder, 5-10 parts of glass fiber and 1-5 parts of silane coupling agent. The damping rubber plate is a free damping structure, so that the damping rubber plate has poor vibration and noise reduction effects; in addition, the use is inconvenient, the adhesive is required for sticking, and the construction efficiency is not high.
Therefore, the environment-friendly damping rubber plate which has the advantages of good damping effect, good viscoelasticity, effective shock absorption and noise reduction, excellent thermal stability, flame retardance and environmental protection, high material utilization rate, wide market value and application prospect and very important significance for promoting the development of the damping material industry is developed.
