Abstract

The invention provides a nanometer enhanced paper plastic material and a preparation method thereof. Well mixing, granulation, extrusion moulding and other steps are carried out for waste paper powder, high density polyethylene, a filling material, an anti-oxidant, a coupling agent, a lubricant and nanometer cellulose and other materials; and the nanometer enhanced paper plastic material which can be applied to the fields of outdoor floors, plank roads, corridors, packages and the like is obtained. Granular materials which have good dispersibility and are suitable for continuous industrial production are prepared by using reclaimed waste paper materials, nanometer cellulose is added, so that the material has higher mechanical properties, and application fields of paper plastic composite materials are enlarged; nanometer cellulose with modified functions is added for realization of electromagnetic shielding, antibiosis or luminescence and other additional effects; added values of paper plastic composite materials are increased, and at the same time, the material has important meanings for reducing environmental pollution.

Description

technical field [0001] The invention belongs to the field of wood-plastic composite materials, and in particular relates to nanocellulose-reinforced paper-plastic materials and a manufacturing method thereof. Background technique [0002] With the increasing amount of recycled paper in the world, how to use these waste paper with high added value has become an important issue. Chinese Patent No.: 201310081384.X discloses a production process of waste paper made of polyethylene composite material: combine the regenerated waste paper powder with alkaline solution and send it to the mixer under the condition of 30-40°C and 50r / min. After mixing, hot pressing molding. It proves the feasibility of using waste paper as raw material for composite materials. However, the dispersion of waste paper in the composite material prepared by this method is not good, and it is difficult to carry out continuous industrial production. [0003] Chinese Patent No.: 201310006671.4 discloses a ...
