Description
One, technical field
The present invention relates to a kind of material of elastomerics vibroshock and the method for preparation thereof.Particularly be a kind ofly to have high-mechanic performance, high low temperature and change and have elastic polyurethane shock-absorber material of good stiffness stability and preparation method thereof down.The elastomerics vibroshock of the wind power plant that the present invention is mainly used in the elastomerics cushioning product of mechanical means and vehicle etc. and the supporting capacity and the rigidity stability of material is had strict demand.
Two, background technology
In the organic elastomer material, polyurethane elastomer has best mechanical property, comprises tensile strength, tear strength and wear resisting property.As high-mechanic elastomerics vibroshock material, polyurethane elastomer is at high rigidity (Shao Er 80A~80D) still can have good caoutchouc elasticity and elongation in the scope, General Purpose Rubber need add filler, sacrifices elasticity and elongation just can reach the required modulus of high-mechanic as cost hardness significantly.Polyurethane elastomer can reach the bearing capacity with the several times of volume General Purpose Rubber under the prerequisite that keeps caoutchouc elasticity and elongation.Be used for the elastomerics bumper and absorbing shock and use, can reduce the volume and weight of equipment shock mitigation system parts significantly, reduce the cost that designs and produces of equipment.Polyurethane elastomer material embodies the good energy absorption to repeated stress to the after reaction characteristics of repeated stress simultaneously, is suitable for very much the elastomerics cushioning material.
Polyurethane elastomer is as elastomerics vibroshock material, and especially the occasion of having relatively high expectations at supporting capacity also used comparatively widely by the abundant cognition of industry, but some characteristics of polyurethane elastomer has limited its application again.Material stiffness is the important indicator of elastomerics vibroshock, and a great deal of application scenario that higher damping requirement is arranged has all proposed strict demand to aspect such as rigidity stability in the rigidity of elastomer material and the whole operating temperature range.As the elastomerics damping of large-scale wind electricity equipment, very high requirement has been proposed simultaneously in physical strength, to of the strict demand of product rigidity in the performances such as velocity of variation, low-temperature performance and compression set of broad operating temperature range to material.The conventional polyurethanes elastomerics satisfies above requirement because of the reason of material structure characteristic simultaneously than difficulty.Mainly show: polyurethane elastomer material has the crystallization tendency of molecular structure, and crystallization property is the textural factor that polyurethane elastomer has the elastomer material optimal mechanical strength, and crystallization degree has significantly influence to polyurethane elastomer rigidity simultaneously.Because the physical strength of polyurethane elastomer depends primarily on the regularity of chemical structure, i.e. the crystallization of polyurethane elastomer tendency, the particularly crystallization of soft chain segment tendency.Promptly be beneficial to the crystalline factor, can both improve elastomeric physical strength.The external factor that influences the generation of polyurethane elastomer molecular crystal is temperature and stress orientation.Yet, the factor of temperature wherein, promptly crystallization degree varies with temperature and the characteristic that significantly changes, is very disadvantageous to the rigidity stability in the product use temperature scope.Like this, just need find optimum balance, make the polyurethane elastomer of preparation be inclined to Grain Full foot material stiffness with the temperature-stable requirement in the crystallization of use temperature scope by the design of prescription and technology; Keep simultaneously and reach higher physical strength, need possess the rapid crystallizing power under the external force alignment conditions; And when the design of Recipe, also need take into account product application to aspect performance requriementss such as the low-temp. low-voltage change of material, biochemical stabilities.
