ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a heat-resistant toothed belt, and more specifically, a magnesium oxide-aluminum oxide solid solution is added as an acid acceptor to at least the back surface of the belt, which undergoes repeated expansion and contraction deformation during belt running. The present invention relates to a toothed belt with excellent heat resistance that uses the added chlorosulfonated polyethylene rubber composition.

クランクを生じるという問題が発生した。(Prior Art) In recent years, against the background of social demands for energy saving and compactness, the temperature in the engine room of automobiles has been rising compared to the past. Along with this, the environmental temperature in which toothed belts are used has also become higher. Conventionally, polychloroprene rubber has been mainly used for toothed belts, but in high-temperature atmospheres, the rubber hardens, causing problems such as early cranking of the belt back surface and tooth base.

には至っていない。To address this phenomenon of premature failure of toothed belts, improvements in the heat resistance of chloroprene rubber have been considered and improvements have been made to some extent, but as long as chloroprene rubber is used, there is a limit. It has not yet achieved sufficient effect.

９８９，８６８号明細書に開示されている。Among polymers with excellent heat resistance, chlorosulfonated polyethylene is equivalent to chloroprene rubber in terms of dynamic fatigue resistance, oil resistance, and adhesion, but water resistance is affected by the vulcanization system, especially the acid acceptor. is large. Usually, MgO, P are used as acid acceptors for chlorosulfonated polyethylene.
Oxides such as bO are used. For example, a rubber composition made by adding an acid acceptor such as MgO or PbO to chlorosulfonated polyethylene is used in the main body of a toothed belt to improve the heat resistance of the toothed belt. That is, U.S. Patent No. 3,
No. 989,868.

。(Problems to be Solved by the Invention) However, if a lead compound acid acceptor such as pbo or pb3o4 is used, a toothed belt with good water resistance can be obtained. It is not recommended to use
Furthermore, when MgO is used as an acid acceptor, water resistance is significantly impaired by MgCl2 generated during the crosslinking reaction.
Adaptation to toothed belts was inappropriate. On the other hand, if an epoxy-based acid acceptor is used as an acid acceptor other than a total oxide, it is possible to obtain a composition with good water resistance, but it may cause odor problems and cause discomfort to the human body. There was a drawback of giving.

る。(Means for Solving the Problems) That is, the present invention is characterized in that a chlorosulfonated polyethylene rubber is formed by adding and mixing a magnesium oxide-aluminum oxide solid solution as an acid acceptor to at least the back surface of a toothed belt. The chlorosulfonated polyethylene rubber composition contains 1 to 5 parts of magnesium oxide-aluminum oxide solid solution per 100 M parts of chlorosulfonated polyethylene.

なる。When the toothed belt (1) is run in a high-temperature atmosphere, the rubber layers of the back surface (6) and teeth (2) of the toothed belt are placed in an environment where they are susceptible to chemical thermal deterioration. The back portion (6) is repeatedly subjected to expansion and contraction deformation as it expands when the belt engages with the boob and is released when the belt disengages. For this reason, when the rubber of the belt main body deteriorates due to heat and begins to increase its hardness, the rubber located on the back surface (6) lacks elasticity and will cause cranking at an early stage.

る。The amount of the acid acceptor added is chlorosulfonated polyethylene 1
1 to 50 parts by weight, preferably 4 to 2 parts by weight per 00 parts by weight
In this case, if the magnesium oxide-aluminum oxide solid solution is 1 part by weight or less, hydrogen chloride generated during crosslinking cannot be sufficiently removed, so the number of crosslinking points in the chlorosulfonated polyethylene decreases and This results in a toothed belt that lacks heat resistance and is prone to early cracking. On the other hand, if the amount exceeds 50 parts by weight, the Mooney viscosity becomes extremely high, causing processing problems. Therefore, the rubber composition used in the toothed belt of the present invention is one in which a magnesium oxide-aluminum oxide solid solution is added to chlorosulfonated polyethylene within the above range in order to improve belt life and satisfy processability. is the most preferred and necessary.

Needless to say, it is not something that can be done.

ゴム組成物に比べ著しく劣っていることが分る。As is clear from Table 2, the rubber composition used in the toothed belt of the present invention shows less increase in hardness, less modulus, and less decrease in elongation than the conventional chloroprene rubber composition, and has much better heat resistance. It also has slightly better water resistance than conventional chloroprene rubber compositions. On the other hand, it can be seen that a rubber composition using MgO as an acid acceptor in chlorosulfonated polyethylene is significantly inferior in water resistance to a conventional chloroprene rubber composition.

By using this, the heat resistance of the rubber layer is increased, which suppresses the occurrence of cranks due to increased hardness in high-temperature atmospheres and the adhesion of the back of the belt, and extends the belt life even under running conditions in high-temperature atmospheres. It has an excellent effect that can greatly improve the
