Description
Technical Field
The invention relates to the technical field of tire production, in particular to a tire inner tube anti-adhesion treatment device and a treatment method with compact structure, good uniformity and strong adhesive force.
Background
The release agent is an additive for releasing. Due to the special self-adhesiveness of rubber, a thin isolating layer is formed between rubber products after the isolating agent is coated in the rubber processing, so that mutual adhesion is blocked or slowed down, and the process operation is convenient.
In the current production process of the automobile inner tube, the inner tube is required to be extruded, in order to prevent the inner tube from being bonded with a production line during extrusion and prevent the extruded tube tubes from being bonded together, and meanwhile, in order to help the stretched tube blank to keep good shaping in vulcanization shaping, the inner tube is generally manually coated or sprayed with a solid separant such as talcum powder and the like, and a part of the inner tube is also sprayed with a liquid separant. However, the solid isolating agent easily causes dust in the production environment to fly, causes certain damage to the body of staff, causes the pollution of the inner tube to the mold and the difficult demolding in the vulcanization stage, and easily causes a slight gap between the valve and the valve core, so that the phenomenon of slow air leakage at the valve edge is caused to affect the product quality. Although the liquid isolating agent avoids the problems of dust flying and easy fine gap formation, the existing liquid isolating agent spraying device is easy to cause non-uniformity after spraying, and the sprayed inner isolating agent is not easy to dry, thereby influencing the production of the subsequent process and increasing the product quality defect.
In the prior art, in order to solve the spraying problem of the liquid separant, a separant inner injector or a core mold is arranged in an extrusion head of an inner tire tube, an air inlet pipeline and a separant inlet pipeline are respectively arranged outside the extrusion head and communicated with an inner cavity of the separant inner injector or the core mold, the separant inner injector is connected with a cyclone nozzle through a spray pipe, or a spray groove is arranged at the near extrusion end of the core mold and a spray nozzle is arranged at the bottom of the spray groove, so that the inner separant liquid and compressed air are fully and uniformly mixed and then form mist to be sprayed to the inner wall of the inner tire tube through the cyclone nozzle or the spray nozzle. The cyclone nozzle or the nozzle is vertical to the spray pipe and the mixing cavity in the middle of the core mold, so that the spray pressure loss is large, the adhesive force after spraying is limited, and the inner tire tube is easy to fall off in the transportation and subsequent production processes after spraying, thereby influencing the production of the subsequent process; in addition, the liquid isolation is sprayed through the cyclone nozzles or the nozzles, the spraying blockage can be caused due to the undersize diameters of the cyclone nozzles or the nozzles, so that the number of the cyclone nozzles or the nozzles is limited, the coverage and the overlapping range of the nozzles or the nozzles are limited, and the isolation liquid sprayed on the inner wall of the inner tire tube is difficult to be uniform.

9. The tire inner tube anti-adhesion treatment method according to claim 8, further comprising the steps of preparing an external spacer fluid, heating and stirring, and performing high-pressure treatment, and specifically comprises the following steps:
D. preparing an external isolation liquid: mixing water, an inner tube release agent and talcum powder according to a ratio of 50: 1.5-2: mixing the components in a mass ratio of 1.5-3 to obtain an outer isolation liquid;
E. heating and stirring: putting the external isolation liquid into a stirring container, stirring and heating to 40-55 ℃;
F. high-pressure treatment: heating and mixing the inner part of the stirring containerThe chaotropic liquid is pumped into the liquid inlet pipe (601) by a high pressure pump, so that the pressure in the immersion cavity (603) is kept between 1.5 and 3kgf/cm2。
10. The method for treating the tire inner tube to prevent adhesion according to claim 9, wherein the talcum powder is further pretreated before being added into the outer spacer fluid, and the pretreatment comprises the steps of adding a proper amount of water into the talcum powder, heating to 60-70 ℃, and soaking for at least 24 hours under heat preservation.
