Description
Technical Field
The invention relates to an environment-friendly Polycarbonate (PC)/polyester composite material, a preparation method and application thereof, and an intelligent irrigation control machine well house prepared from the composite material.
Background
Polycarbonate is a non-crystalline polymer material, and has excellent impact resistance, dimensional stability, thermal stability, high glossiness, excellent mechanical property, electric insulation property and flame retardant property. But the defects of large molecular rigidity and steric hindrance, high melting temperature, difficult molding and processing, more importantly, large residual stress of the product, easy stress cracking, poor solvent resistance, high cost and the like limit the application of the polycarbonate in practice.
Polyester materials, such as polybutylene terephthalate (PBT), polyethylene terephthalate (PET), and poly (butylene terephthalate-co-adipate butylene glycol) ester (PBAT), have very excellent chemical resistance, heat resistance, and excellent mechanical strength, electrical insulation characteristics, and thermal stability. But the product has the defects of large shrinkage rate, low notch impact strength and the like.
The alloying of the material can make up for the deficiencies and can fully exert the advantages of each component. Therefore, the PC/polyester alloy material has excellent molding processability, better impact resistance, chemical resistance and other excellent characteristics, particularly aging resistance, and has unique advantages in aging compared with the traditional PC/ABS alloy material. The polyester can improve the fluidity, stress cracking and solvent resistance of PC, and can also improve the defect that polyester material products are easy to warp and deform. But the ester exchange reaction can occur between PC and polyester in the blending process, which affects the performance of the alloy material and generally needs to add an ester exchange inhibitor; on the other hand, the compatibility of PC and polyester is poor, and the compatibility and the comprehensive mechanical property of the alloy material can be improved only by adding a compatible toughening agent. In order to expand the application field of PC/polyester, the added light stabilizer and the flame retardant can be applied to the field of outdoor products, such as national grid control boxes and agricultural intelligent irrigation control machine well rooms. While relatively few studies have been made, the present patent application can provide a reference to this technical breakthrough.
