The difference between the embodiment and the embodiment 1 is that the content of rosin and the roller temperature are increased, the viscosity of the glue oil can be increased, the production time can be reduced, and the light rail tire with larger volume or larger design requirement is provided. The bonding and fixing effect of the light rail tire blank material on the forming drum is better, and the light rail tire blank material can be conveniently peeled off after being fixed; meanwhile, the glue oil in the formula does not use a vulcanization formula and does not participate in the subsequent vulcanization process of the light rail tire, so that the molding quality of the light rail tire is not influenced even if residues exist, and the use is convenient and efficient.
The rubber oil prepared by the formula can slip when the roller temperature is too low during production, and is not beneficial to rapid plastication. If the temperature is too high, the roll temperature is higher during subsequent mixing, which is not favorable for feeding. Through proper roller temperature, the production efficiency can be effectively improved, and resources are saved. Facilitating rapid mixing of the materials.
The natural rubber SCR5 and rosin are used as main tackifying materials to provide a main viscosity source for the gum oil, and the No. 120 gasoline is used as a solvent, so that the prepared gum oil is similar to the gum cement in state and is convenient to brush when in use; the zinc oxide plays a role in separation, so that over-adhesion is avoided, and the green tire can not be separated completely after molding; the calcium hydroxide is intended to act as a thickening agent, to prevent overflow during brushing, and also to act as a curing agent.
When the light rail tire is produced, the tire needs to be strong in viscosity, can be adhered with metal and can be adhered with glue materials, but the viscosity cannot be too strong, so that the tire can be smoothly taken off after the tire is completely molded; the molding drum is not polluted, the vulcanization of the light rail tire is not participated, and the preparation process of the light rail tire is not influenced, so that the sulfur/accelerator cannot be added, namely, a vulcanization related formula system cannot be used. Therefore, various glues in the prior art cannot be directly used in the light rail tire production process, such as: after the synthetic epoxy resin glue or the nitrile rubber adhesive glue is coated, a harder solidification similar to vulcanization can be formed after the solvent is volatilized, and the stripping is difficult; firstly, the material contacting the green tire and the glue is easy to strip off by stripping; secondly, a solidified hard object is formed on the forming drum, and the processing is difficult; thirdly, the brush is easy to solidify. After the glue oil is brushed, a thin and soft film is formed by curing, the thin and soft film is easy to separate, the brush can be softened when new glue oil is brushed again, hard objects cannot be formed on the forming drum, and the glue oil can be repeatedly used for many times.
The production working principle of the light rail tire is as follows: before a building drum is ready for building combination, the light rail tire needs to be coated with glue oil on two sides of the drum, a brush is used for adhering the glue oil, then the light rail tire is uniformly brushed on two sides of the building drum in the circumferential direction, the building drum is brushed and rotated simultaneously, after the light rail tire is rotated for 10 seconds, a first layer of material is coated and pressed, the first layer of material is tightly adhered on two sides of the building drum, after the appearance of the light rail tire is checked in the circumferential direction to be normal, the materials of the later layers are continuously coated, after all the materials are coated, the appearance of the tire blank is checked, and the tire blank is detached from the building drum after the tire blank is normal. Before the next embryo is produced, the step of brushing the glue oil is repeated.
The glue oil disclosed by the invention is simple in preparation method and low in cost, can effectively improve the viscosity between each part subjected to laminating molding and the molding drum, improves the positioning effect of each part, improves the tire quality, and can be easily cleaned and peeled from the molding drum.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
