Abstract

The invention provides a toughened and reinforced recycled PP (polypropylene) composite material. The composite material comprises the following components in parts by weight: 50-70 parts of recycled PP resin; 10-20 parts of PBAT resin; 10-30 parts of wood powder fiber; 1-3 parts of a compatilizer; and 0.1-0.3 parts of an antioxidant. The notch impact strength of the composite material is greater than or equal to 25KJ / m<2>, the bending strength is greater than or equal to 50MPa, and the flexural modulus is greater than or equal to 3000MPa. The recycled PP composite material can be applied to household appliances.

Description

technical field [0001] The invention relates to the technical field of waste plastic recycling and utilization, and more specifically, to a toughened and reinforced recycled PP composite material and its preparation method and application. Background technique [0002] After decades of development, the widespread use of plastic products has accumulated more and more non-degradable plastic waste, which seriously pollutes the environment. In order to save energy, protect the environment, and beautify the environment, we can't wait to deal with plastic waste. [0003] Recyclable polypropylene resin (PP) mainly has large performance differences. The performance of the overall recycled PP resin is not as good as that of the new material PP resin. Although the impact performance of the copolymerized recycled PP is higher than that of the homopolymerized recycled PP, the overall performance is still the same. poor. [0004] The current Chinese patent (CN105885220A) discloses a PP ...
