Embodiment 1

[0019] The polyester cord is placed on the transmission device, and the transmission device carries the polyester cord into the irradiation room at a certain speed, and passes through the scanning window of the electron accelerator in the irradiation room to complete the irradiation of the polyester cord. When the polyester cord passes through the scanning window of the electron accelerator, the electron beam energy of the electron accelerator is 1MeV, the beam current intensity of the electron beam is 8mA, the temperature of the irradiation room is 30°C, and the transmission speed of the transmission device is 5m / min. The irradiation dose is 40kGy, normal pressure, air atmosphere, and the irradiation times are 1 time. After irradiation, the second dipping method is used for dipping. The dipping method is to scrape the sample by hand, and the rubber is covered with natural rubber to obtain polyester cord. The adhesion test of the polyester cord was carried out according to the...

Abstract

The invention relates to a method for improving adhesive force between a polyester cord and coating rubber. The method comprises the following steps of: firstly, carrying out electron beam irradiationon the polyester cord; and secondly, dipping and coating the polyester cord subjected to electron beam irradiation to obtain a polyester cord fabric. According to the method, the electron beam irradiation modification process is added prior to a process of preparing the polyester cord fabric by adopting the secondary dipping method, and the polyester cord can be modified by adopting online embedding or offline irradiation, so that the activity of the polyester cord is improved, the dipping processing cost is reduced, the production process is optimized, the adhesive force between the cord andthe coating rubber is improved, and the quality of the cord fabric is stable. The method is environment-friendly, simple in process and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of rubber tire processing, in particular to a method for improving the adhesion between polyester cords and rubber-covered rubber. Background technique [0002] Cord fabric is one of the main raw materials for tire production. It is mainly used to prepare the skeleton material of the tire. The quality of the carcass ply has an important impact on the performance and life of the tire. The cord fabric is woven from cords. There are four main types of cords: (1) viscose cords; (2) polyamide cords; (3) polyester cords; (4) aromatic polyamide cords. Amide cord. The development trend of semi-steel radial tires as tire cords. The commonly used material is polyester cord fabric. The carcass ply is composed of polyester cords and rubber-coated rubber through the bonding force between the two. However, the crystallinity of polyester molecules High, low activity, low direct binding force with rubber materials. At pr...
