Abstract

The invention provides an environment-friendly polycarbonate / polyester composite material and a preparation method and application thereof. The environment-friendly polycarbonate / polyester composite material is prepared from the following components in parts by weight: 30-80 parts of polyester, 20-60 parts of polycarbonate, 5-30 parts of glass fibers, 1-5 parts of an ester exchange inhibitor, 1-5parts of a flexibilizer, 0.5-10 parts of a compatilizer, 1-20 parts of a flame retardant, 0.1-1 part of an antioxidant, 0.1-1 part of an anti-UL agent, 0.1-1 part of a lubricating agent and 0.1-0.5 part of a coupling agent. The environment-friendly polycarbonate / polyester composite material provided by the invention has excellent mechanical properties, flame retardance and ageing resistance, the preparation method of the environment-friendly polycarbonate / polyester composite material is simple in process, and the production cost of the environment-friendly polycarbonate / polyester composite material is lowered.

Description

technical field [0001] The invention relates to an environment-friendly polycarbonate (PC) / polyester composite material, its preparation method and application, and an intelligent irrigation control well house prepared by the composite material. Background technique [0002] Polycarbonate is a non-crystalline polymer material with excellent impact resistance, dimensional stability, thermal stability, high gloss and excellent mechanical properties, electrical insulation and flame retardancy. However, its molecular rigidity and steric hindrance are large, its melting temperature is high, and molding processing is difficult. More importantly, its products have large residual stress, are prone to stress cracking, and have poor solvent resistance. In addition, the disadvantages of high cost limit the use of polycarbonate. practical application. [0003] Polyester materials such as polybutylene terephthalate (PBT), polyethylene terephthalate (PET), and poly(butylene terephthalate...
