Abstract

The invention provides a waste paper reinforced recycled high density polyethylene composite material, which is characterized by comprising the following raw materials by mass percentage: 5 to 15 percent of waste paper, 85 to 95 percent of recycled high density polyethylene, 0 to 4 percent of coupling agent and 0 to 10 percent of compatilizer. The waste paper is mixed with the recycled HDPE, the coupling agent and the compatilizer after fiber dispersion, and the mixture is sent into an open dual-roller mixing device for mixing and homogenizing, pressed by a section mold, and then cooled, demoulded and made into the waste paper reinforced recycled high density polyethylene composite material. The waste paper reinforced recycled high density polyethylene composite material not only can fully utilize the waste paper and waste plastics and change the waste into the valuable but also can greatly improve the comprehensive utilization level of waste resources and save a large number of resources, and simultaneously can reduce the environmental pollution caused by mismanagement of waste material resources. Moreover, the waste paper reinforced recycled high density polyethylene composite material has the advantages of simple technique, short flow, low investment, no pollutant emission, energy conservation and low consumption, low cost of the raw materials, good texture and high strength of the composite material obtained, and no harmful gas emission, and is a waste utilization project which is favorable for the country, the people and the enterprises.

Description

technical field [0001] The invention relates to a composite material, in particular to a waste paper reinforced recycled high-density polyethylene composite material, which belongs to the technical field of material processing. Background technique [0002] Waste paper is a secondary fiber that contains a lot of impurities and does not have thermoplasticity. The recycling rate of waste paper in our country is low, and a large amount of waste paper has not been properly recycled, resulting in a great waste of resources. [0003] In order to protect the environment, reduce the processing load of municipal solid waste (of which waste paper accounts for about 1 / 3), reduce the felling of forest logs, and maintain ecological balance, it is an important topic that people pay attention to to study the recycling and utilization of waste paper. At present, countries around the world have made great progress in the research on waste paper recycling technology. my country's waste pape...
