Abstract

The invention discloses a PET / PP alloy material and a preparation method thereof. The invention discloses a PET / PP alloy material, which is prepared from the following components according to the mass percentage proportions: 20-50% of PET, 20-50% of PP, 3-8% of compatibilizer, 10-30% of reinforcing agent, 15-20% of composite fire retardant, 0.5-2% of lubricant, and 0.1-1% of anti-oxidant. The beneficial effects reside in that: the PET / PP blending alloy material provided by the invention has both advantages of PET and PP, has excellent comprehensive properties; simultaneously, proper amounts of reinforcing agent and composite fire retardant are added, in order to effectively improve mechanical properties and flame retardation performance of the PET / PP alloy material, and make the PET / PP blending alloy material have advantages of high notch impact strength, excellent bendability, and good flame retardation effect; and the PET / PP blending alloy material is widely applied in the fields of automobile, household electrical appliance, toy and machinery, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PET / PP alloy material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is mainly used in synthetic fibers, biaxially stretched films, and hollow containers. Due to PET's low price, excellent wear resistance, heat resistance, chemical resistance, electrical insulation, molding dimensional stability and high mechanical strength, PET was widely used as an engineering plastic in the 1960s. application. PET for engineering plastics has excellent comprehensive performance and low price, which is very competitive compared with other general engineering plastics. There are rigid groups on the main chain of PET molecules, so its heat resistance is very high, and its electrical properties are also excellent due to the high symmetry of the molecular chain. However, PET also has disadvantages such as slow crystallization speed, d...
