Abstract
The invention discloses a composite enhanced PET (polyethylene terephthalate) material. The PET composite material is prepared from the following components in percentage by weight: 70% of PET resin, 12% of modified bentonite, 14% of rock powder, 1% of assistant, 1% of heat stabilizer and 2% of plasticizer. The composite enhanced PET composite material has the advantages of simple production technique, low cost, favorable gas barrier property, favorable impact resistance and excellent heat stability. The strong composite enhanced PET material has excellent physical and mechanical properties, and the impact strength, tensile strength and modulus are greatly enhanced, thereby satisfying the requirements for the production technique and service performance in multiple occasions. The strong composite enhanced PET material has higher light transmittance, fire resistance and freeze resistance.
