等種々問題があった。In recent years, as machines have become lighter, synthetic resin products have come to be used in large numbers as machine parts, and synthetic resins with excellent sliding properties are required for bearings. Conventionally, polyamide, polyacetal, polyethylene, fluororesin, etc. have been used as synthetic resins with good sliding properties. These can function without lubrication at low loads and low speeds, but as the load and high speeds increase, they seize or flow due to frictional heat, making them unusable. Fluororesins, especially tetrafluoroethylene resins, show excellent sliding properties by adding fillers to improve wear properties, but these can only be molded by compression molding and are extremely expensive. It has its drawbacks. Therefore, measures have been taken to improve the sliding properties by adding solid lubricants to other synthetic resins, but this method does not sufficiently improve the sliding properties under high speed and high loads. In addition, in order to solve the above problem, there is a method of adding lubricating oil to synthetic resin to create a so-called oil-impregnated plastic. Specific methods include 1) simply mixing lubricating oil into the resin, and 2) retaining lubricating oil. 3) In addition to 1) and 2) above, a fibrous filler may be added as an oil conductor. Such oil-impregnated plastics are intended to have sliding properties by leaching lubricating oil, but (1) the coefficient of friction is low and unstable; (2)
) Oil leaks out when heated, (3) Formability is poor, (4) Sliding carrier remover scrapes the mating material, (5) Oil easily separates during molding or cross-wiring, ( There were various problems such as 6) deterioration of material properties, (7) oil on the sliding surface and dust etc., and (8) abnormal wear when the oil ran out.
以上述べたように、従来の技術においては、摩擦係数が

題があった。As mentioned above, in the conventional technology, the friction coefficient is stable at a low value, the wear coefficient is small, and the mechanical properties (
In particular, it is impossible to obtain a material that does not cause a decrease in strength.
Even though synthetic resins have many excellent properties, there is a problem in that they are not suitable for sliding materials that require low friction and wear resistance.

The reason why 0.5 to 30.0 parts of organopolysiloxane having an isocyanate group or a unit containing a cyanate group is blended is that if the amount is less than this lower limit, the effect of improving sliding properties is insufficient; If the amount is too large, the mechanical properties of the synthetic resin will significantly deteriorate, which is undesirable, and the amount is preferably in the range of 2.0 to 20.0 parts. Further, in order to promote the reaction, it is preferable to add a trimerization catalyst such as calcium acetate or a tin compound.

の欠点がすべて解消されるものと考えられる。In the lubricating resin composition of the present invention, the functional groups of the organopolysiloxane are trimerized to form a three-dimensional network having the lubricating properties of the organopolysiloxane in the synthetic resin, and the network is finely dispersed. Because the lubricating substance exists in the base material, it has a small coefficient of friction, and since the lubricating substance remains within the tissue without being extracted from the base material, the coefficient of friction is maintained stably, and the network reinforces the base material to prevent wear. It is thought that all the drawbacks of conventional oil-impregnated plastics can be overcome without any decrease in mechanical strength.

On the other hand, Examples 1 to 10 all have small friction coefficients and wear coefficients without decreasing tensile strength, have good moldability, and do not exhibit the drawbacks of ordinary oil-impregnated plastics, and are extremely preferable. there were. In addition, since the purpose of low friction and low wear is achieved without adding hard fillers, which have been widely used in the past, the counter material will not be damaged during sliding.
