Embodiment 1
[0025] A process for producing anticorrosion materials for chemical pipelines, comprising the following steps:
[0026] S1. Formula: It includes the following raw material components in weight percentage:
[0027] 55-60% polyethylene terephthalate, 10-20% ethylene glycol modified - polyethylene terephthalate, 6-9% polybutylene terephthalate, 2-5 % thermoplastic elastomer, 3-5% plasticizer, 0.2-0.5% antioxidant, 0.1-0.5% auxiliary crosslinking agent.
[0028] S2. Blending of raw materials: put the raw materials in step S1 into a two-roll kneader, and control the temperature of the two-roll kneader at 100-120° C. for 10-15 min.
[0029] S3. Granulation: Put the mixed raw materials into the granulator to carry out the mixing and granulation of the raw materials.
[0030] S4. Radiation crosslinking: use an electron accelerator to carry out the granulation of the raw materials in step S3 under the conditions of electron beam energy of 0.5-1.0MeV, radiation dose of 8-12kGy and rad...
