タイヤ成型用機型剤が提案されている。When molding an unvulcanized green tire in the vulcanization process, it is common practice to expand a bag called a bladder with hot water or steam on the inner surface of the green tire and then insert it into a mold. When vulcanizing, good lubricity is required between the inner surface of the tire and the bag, and when the bag is deflated after vulcanization, the bag and the inner surface of the vulcanized tire may be separated from each other, or the bag may In tire molding, it is essential to use a mold release agent containing mica powder or talc powder to facilitate the removal of air trapped between the inner surface of the tire and the inner surface of the tire. Traditionally, tire molding agents are mainly composed of rubber volatile oil or gasoline, mixed with mica powder, talc powder, and silicone oil, which is atomized and applied to the inner surface of the tire, and then coated with a large amount of solvent. Tires were produced by evaporating some rubber volatile oil or gasoline and then vulcanizing the raw tires in a vulcanizer. In other words, large amounts of petroleum-based solvents have been used, but the solvents pose an explosion and fire hazard, air pollution due to the solvents dispersing into the air, and
It had many disadvantages such as solvent poisoning of employees and wasted resources due to the use of solvents. In order to solve these problems, a tire molding agent of this type using water instead of the petroleum solvent has been proposed.

した。However, with this water-type scale-type agent, depending on the mixing method or long-term storage when mixing mica powder or turk powder, the powder components may separate, and the emulsifying and dispersing agent used may cause spoilage or mold growth. Practical drawbacks such as encouraging
Furthermore, it was disadvantageous in terms of volume during transportation, packaging, and storage. The inventors of the present invention have overcome the above-mentioned drawbacks.As a result of various studies, we have found that a free-flowing powder mold release agent for tire molding has good storage stability, and can be used simply by dispersing it in water. The present invention has been achieved by discovering a composition that provides mold release performance.

る。The composition of the present invention can be made by mixing the above components in any manner. One good method for making it is to thoroughly mix one or more dispersing emulsifiers (Component [B]) and diorganopolysiloxane (Component [A]), and then disperse them in mica or talc powder (Component [C]). By doing so, a good powdery mold release agent for tire molding can be obtained. By gradually adding this powdered mold release agent into a container containing water during tire molding, a water-type mold release agent of any viscosity can be obtained. It is also possible to dissolve and disperse it using inpropyl alcohol containing a small amount of water or gasoline containing a small amount of water. In addition to the above essential ingredients, the composition of the present invention contains rust inhibitors such as magnesium stearate, sodium nitrite, amine salts, phosphates to inhibit rust, rot or mold growth. Preservatives and fungicides such as formalin, dehydroacetic acid, sodium dehydroacetate, benzoic acid, sodium benzoate, sorbic acid, and sodium sorbate, or pigments and dyes as coloring agents can also be used in combination.
