本発明は、ウレタンゴム成型体を、金属、プラスチック

いる。Vulcanization is generally used when bonding rubber to metal, plastic, or other rubber molded objects. It cannot be used when the object cannot be set in a mold or when it is desired to avoid imparting heat history to the object to be bonded. In such cases, conventionally, a reactive pre-treatment agent, so-called primer, is applied to the adhesive surface of the rubber product, which has been vulcanized and molded into a predetermined shape, and then heat treated. For example, bonding is performed using an epoxy adhesive.

用時に加えられる外力によつて接着部がはがれやすく、
さらにフエノキシ樹脂は吸水性のため、高温水にさらさ
れると更に接着力が低下するという欠点を有している。Here, phenoxy resin is conventionally known as a primer for urethane rubber, but it does not necessarily give a sufficient adhesive strength on the adhesive surface. The adhesive part is likely to peel off due to external force applied during use at temperatures above
Furthermore, since phenoxy resin is water-absorbing, it has the disadvantage that its adhesive strength further decreases when exposed to high-temperature water.
本発明は、このような従来の難点を解消すべくなされた

The aim is to provide a product with improved heat resistance and hot water resistance, and high adhesive strength. In order to achieve the above object, the present invention uses an organic tin compound represented by the chemical formula [wherein R1CmH2] per 100 parts by weight of phenoxy resin.

．． If it is less than 0.02 parts by weight, the effect will be small, and if it is more than 1.0 parts by weight, it will accelerate the hydrolysis of the urethane rubber, making it unsuitable for use when exposed to water or in a high temperature and humid atmosphere. Preferably it is 0.05 to 0.5 part by weight. In carrying out the present invention, first, urethane rubber is filled into a mold by a known method, molded under heat and pressure, and at the same time, the urethane rubber is vulcanized (crosslinked). Next, a rubber brimer is applied to the adhesion surface of the rubber molded body by brushing, spraying, or other suitable means and dried. Thereafter, the adhesive surface of this rubber molded body and an object to be adhered, such as a metal member, are adhered using a known adhesive such as an epoxy adhesive.

れる。As described above, by using the rubber primer of the present invention, a product with improved heat resistance and hot water resistance and high adhesive strength can be obtained.

造が簡単ですみ、安価に製作することが出来る。In addition, since there is no need to apply heat history to the object to which the rubber molded body is bonded, it is suitable for applying rubber lining to the surfaces of various devices, for example, and the mold used is Since it is simply molded from rubber, the structure is simple and can be manufactured at low cost.
