[Technical Field of the Invention] The present invention relates to constituent materials of air springs used in vehicle suspension systems and the like. [Prior Art] Air springs used in vehicle suspension systems and the like are formed by molding a flexible material such as rubber into a substantially cylindrical shape, and two layers of reinforcing members are embedded inside the spring. This reinforcing member is made of synthetic fiber blind fabric such as nylon fiber, and is composed of warp yarns that provide reinforcement and weft yarns that maintain the density of the warp yarns, and each warp yarn is arranged in a direction that intersects with each other. . The above-mentioned air spring is mechanically attached to the outer cylinder and the end of the oil damper to form an air chamber, which seals air inside and is capable of cushioning the shock by compressive elasticity. These air springs are designed to operate under harsh operating conditions in order to achieve excellent handling stability and ride comfort by controlling the vehicle height, vehicle posture, and spring constant according to changes in the number of passengers and cargo, vehicle speed, and road surface conditions. It is placed below. For this reason, the ambient temperature around the air spring tends to be high, and higher heat resistance than ever before is required. However, conventionally, such air springs have been made of chloroprene rubber, a synthetic rubber with an excellent balance of properties such as heat resistance, cold resistance, bending resistance, oil resistance, and ozone resistance. Ta. However, conventional air springs whose inner and outer layers are made of chloroprene rubber have limited heat resistance and cannot meet new demands for improved heat resistance. I couldn't stand it. In addition, since chloroprene rubber itself has a crystalline structure, it is considered unsuitable for use in cold regions, and has drawbacks such as concerns about dynamic ozone performance. On the other hand, air springs whose inner and outer layers are made of epichlorohydrin-ethylene oxide copolymer rubber or epichlorohydrin-propylene oxide copolymer rubber have better heat resistance, cold resistance, oil resistance, and dynamic ozone resistance than chloroprene rubber. Although it was excellent, it could not be put to practical use because of its poor bending resistance. [Object of the Invention] An object of the present invention is to provide an air spring that is comprehensively excellent in heat resistance, cold resistance, bending resistance, oil resistance, and dynamic ozone resistance. [Structure of the Invention] For this reason, the present invention provides an air spring in which a reinforcing member is disposed between an inner layer and an outer layer, in which either the inner layer and the outer layer or the inner layer and the outer layer are made of epichlorohydrin-propylene oxide-unsaturated epoxide. The gist of this invention is an air spring characterized by being composed of a rubber mixture consisting of 90 to 50% by weight of original copolymer rubber and 10 to 50% by weight of chloroprene rubber. Hereinafter, the configuration of the present invention will be explained in detail. FIG. 1 is a partially cutaway front view explanatory view showing the air spring device, and FIG. 2 is an enlarged explanatory view of section A in FIG. 1. In these figures, 1 is an outer cylinder, and 2 is a rubber film constituting an air spring. As shown in FIG. 2, the rubber membrane 2 includes an inner layer 2a, an outer layer 2b, and a reinforcing member layer 2c.
It consists of. In the reinforcing member layer 2c, X 1 is a warp thread on the inner layer side, and X 2 is a warp thread on the outer layer side. 3
is an oil damper and G is an air chamber. In the present invention, in the rubber film 2, the inner layer 2
a and the outer layer 2b or either the inner layer 2a and the outer layer 2b are made of epichlorohydrin-propylene oxide-unsaturated epoxide terpolymer rubber 90~
It consists of a rubber mixture consisting of 50% by weight and 10-50% by weight of chloroprene rubber. The thickness of each of the inner layer 2a and the outer layer 2b is about 0.3 to 1.5 mm. Note that this rubber film 2 is normally placed in a desired mold.
Manufactured by vulcanization at temperatures of 100-250°C. (1) Epichlorohydrin-propylene oxide-
Unsaturated epoxide terpolymer rubber. Examples of unsaturated epoxides include allyl glycidyl ether, glycidyl methacrylate, glycidyl acrylate, and butadiene monoxide. The amount used is 1 to 15 mol%
and more preferably 2 to 10 mol%.
By copolymerizing unsaturated epoxide,
Thermal softening deterioration and dynamic ozone resistance are improved, but if the amount exceeds 15 mol %, hardening type deterioration occurs due to heat, resulting in loss of rubber elasticity and brittle defects. In addition, the amount of prepylene oxide is 30 to 90 mol% depending on the cold resistance required for the rubber molded product.
The amount is determined as appropriate within the range of 30 mol%.
If it is less than 90 mol%, there will be problems with cold resistance, and if it exceeds 90 mol%, oil resistance will decrease and the degree of swelling will increase. Particularly preferable ratios of copolymerization components are 15 to 55 mol% of epichlorohydrin and 35 to 85 mol% of propylene oxide.
mol%, unsaturated epoxide 2-10 mol%. (2) Chloroprene rubber. The chloroprene rubber in the present invention is 2-
It is a homopolymer rubber of chloro-1,3-butadiene or a copolymer rubber of 2-chloro-1,3-butadiene and a monomer copolymerizable therewith, and also includes a sulfur-modified type. (3) Rubber mixture. It consists of 90 to 50% by weight of the above copolymer rubber and 10 to 50% by weight of the above chloroprene rubber. If the copolymer rubber exceeds 90% by weight, the bending resistance decreases, and the
If it is less than % by weight, problems will arise in dynamic ozone resistance. As the vulcanizing agent for this rubber mixture, a sulfur-based vulcanizing agent can be used since it is a mixture of copolymer rubber copolymerized with unsaturated epoxide and chloroprene rubber containing unsaturated double bonds. It is. Furthermore, since both contain chlorine atoms, triazinethiol-based vulcanizing agents and thiourea-based vulcanizing agents that cause a vulcanization reaction via chlorine atoms can also be used. In addition, commonly used reinforcing agents, fillers, softeners, plasticizers,
Antiaging agents, vulcanization accelerators, and the like may be added depending on the embodiment. The present invention will be specifically explained below using Examples. Note that the present invention is characterized by using a specific rubber mixture for the inner layer and outer layer of the air spring, or for either the inner layer and the outer layer, so in the examples, for convenience, the characteristics of the rubber mixture were evaluated. . Numerical values in formulations and rubber mixtures refer to parts by weight. [Example] Epichlorohydrin (30 mol%)-propylene oxide (67 mol%)-allyl glycidyl ether (3 mol%) terpolymer rubber and chloroprene rubber were each mixed according to the formulation shown in Table 1 below. After kneading with the compounding ingredients in a test internal mixer, a compound blending method was adopted in a test roll machine to prepare the compounding ratios shown in Table 2 below. The test piece vulcanization conditions were press vulcanization at 160°C for 30 minutes. Each sample was subjected to JIS Demartyer bending test, air heating aging test, low temperature impact embrittlement test, and oil resistance test.
Conducted in accordance with K6301. In addition, the dynamic ozone deterioration test was conducted under dynamic conditions in which the test piece was given an elongation of 0 to 30% in an atmosphere of 40° C. and an ozone concentration of 50 pphm, and the crack state was determined. The results are shown in Table 2. Note that experiment numbers 1, 2, 6, and 7 indicate comparison columns.
