摘要： PROBLEM TO BE SOLVED: To provide a method for realizing vibration proof characteristics effective against vibration in a wide frequency or amplitude range by forming a sea-island structure with a specific rubber material as the matrix dispersed with specific particles, in order to shift the dynamic magnification-loss tangent value to the low dynamic magnification-high damping side. SOLUTION: This method comprises dispersing (A) a rubber material as the matrix, showing a certain dynamic magnification and loss tangent (tan δ) with (B) finely crushed vulcanized rubber particles showing higher damping than the component A to form a sea-island structure, in order to impart new vibration proof characteristics to the component A by shifting the dynamic magnification-loss tangent value to the low dynamic magnification-high damping side. Dynamic magnification is defined as dynamic spring constant divided by static spring constant (dynamic spring constant/ static spring constant), wherein the former represents vibration transfer and the latter support rigidity. Loss tangent (tan δ) is defined as loss modulus divided by storage modulus (loss modulus/storage modulus), wherein the former represents dynamic modulus whose phase is 90 deg. deviating from the strain's and the latter is dynamic modulus whose phase is the same as the strain's.

摘要： PURPOSE:To improve both the withstanding characteristics to the dynamic ozone and the heat resisting characteristics and optimize the air-permeable inhibition characteristics of the rubber layer at the inner side of a diaphragm by using chlorosulfonated polyethylene composite for both the rubber layers at the inner-pressure side and the atmospheric pressure side of the diaphragm. CONSTITUTION:One end of a diaphragm 3 is stuck to the external face 2 of the shock absorber 1 of the suspension of a vehicle and the other end part is folded reversely and stuck to the open end part of a cylindrical body which is joined to the piston rod 4 of a shock absorber 1 to define an air chamber, thus forming the desired shock absorber assembly. Hydrotarsyte as acid receival agent and chlorosulfonated polyethylene composite containing bismuleimid are used for each of the rubber layer 6 and the rubber layers 7 of the reversely folded diaphragm 3 which are exposed to the inner pressure and the atmospheric pressure in actual operation, with a pair of rubber cord fabric layers 5 centered therebetween in the diaphragm 5.

摘要： PURPOSE:To obtain a treating agent for coating to an oscillating part to prevent the generation of abnormal noise caused by the friction of the oscillating part with other part by including fine particles of a urethane resin in a silicone- copolymerized curable urethane resin. CONSTITUTION:The objective treating agent for suppressing abnormal noise is produced by uniformly mixing (A) a silicone-copolymerized curable urethane resin obtained by reacting a reactive silicone (e.g. hydroxypolydimethylsiloxane) with an isocyanate compound (e.g. tolylene diisocyanate) and a polyol (e.g. polyester polyol), (B) 1-50wt.% (in terms of solid component) of fine particles of a urethane resin having particle diameter of 0.1-40mum (preferably 0.5-20mum) and composed of cross-linked urethane polymer, etc., obtained by the urethanization reaction of a polyisocyanate compound with various hydroxy compounds and (C) a solvent and optionally a catalyst, a cure accelerator, etc. When an interior trim of automobile is treated with the treating agent, the variation range of the kinetic friction coefficient of the treated part to the counter part is decreased to prevent the generation of abnormal noise.

摘要： PROBLEM TO BE SOLVED: To obtain a rubber composition comprising an ethylene-propylene-diene (EPDM) rubber and a diene-based rubber and/or natural rubber where the EPDM rubber is finely dispersed and carbon black is sufficiently prevented from being unevenly distributed, and capable of giving a cured product excellent in physical properties such as tensile strength through quick curing, and to provide a method for producing such a rubber composition. SOLUTION: This rubber composition is a reclaimed EPDM rubber composition obtained by reclaiming a crosslinked EPDM rubber. This composition comprises a reclaimed EPDM rubber, an uncured diene-based rubber and/or natural rubber; wherein the reclaimed EPDM rubber is such that the network chain concentration of the gel fraction is 1/50 to 1/4 time that of the corresponding crosslinked EPDM rubber before reclaimed and the weight-average molecular weight of the sol fraction is 30,000-500,000.
