Abstract

The invention discloses a high-temperature-resistant PET composite board suitable for an outdoor environment. The PET composite board is prepared from, by mass, 70%-85% of PET resin, 5%-12% of coupling agent, 3%-5% of elastomer, 0.5%-2% of light stabilizer, 6%-15% of enhancer and 0.1%-0.2% of antioxidant. The invention further discloses a preparation method of the high-temperature-resistant PET composite board suitable for the outdoor environment.

Description

technical field [0001] The invention relates to a PET composite board suitable for open-air environment. Background technique [0002] PET is derived from the dehydration condensation reaction of ethylene terephthalate. PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface, high strength, good wear resistance, good resilience, and low cost. However, the mechanical properties, heat resistance and impact properties of pure PET materials are poor, and the crystallization rate is slow, making molding and processing difficult. Therefore, PET usually needs to improve its processability and physical properties through toughening, strengthening and crystallization promotion. However, the general PET composite board is either not transparent or has poor heat resistance, so it cannot be used as a protective layer outside the electronic display screen in the open air. Contents of the invention [0003] The technical problem to be solved b...
