High-strength adhesive for tire manufacturing

The invention relates to a high-strength adhesive for tire manufacturing, and belongs to the technical field of adhesives. The formula of the adhesive disclosed by the invention comprises a polyurethane prepolymer, a plasticizer, a silane coupling agent, a powder filler, an anti-aging agent and nano zirconium oxide. According to the adhesive prepared by the preparation method disclosed by the invention, a rubber-polyurethane composite tire interface is firm in adhesion and high in peel strength, and a tire tread and a tire body of a rubber-polyurethane composite structure tire which is adhered by using the high-strength adhesive prepared by the preparation method disclosed by the invention for a long distance do not have a peeling condition. 本发明一种用于轮胎制造的高强度胶黏剂，属于胶黏剂技术领域。本发明公开的胶黏剂配方中包括聚氨酯预聚体、增塑剂、硅烷偶联剂、粉末填料、抗老化剂、纳米氧化锆。本发明制备的胶黏剂使得橡胶-聚氨酯复合轮胎界面粘合牢固，剥离强度高，长距离使用本发明制备的高强度胶黏剂贴合的橡胶-聚氨酯复合结构轮胎，胎面与胎体间也不出现剥离状况。
