Problems solved by technology

[0003] At present, the existing method of using recycled high-density polyethylene to produce wood-plastic profiles has strict restrictions on the melt flow index of recycled high-density polyethylene, which greatly restricts the comprehensive recycling of waste high-density polyethylene plastics; Moreover, the existing wood-plastic profiles produced from high-density polyethylene recycled materials have poor wood grain effects and poor user experience.

Abstract

The invention provides a full-body graining polyethylene plastic wood composite, which includes a mixture formed by a color masterbatch and a base material. The color masterbatch and base material contain a high density polyethylene recycled material, so as to not only reduce the cost of raw materials but also treat the waste plastics in a resource way, and reduce the waste of resources. The low density polyethylene added in the color masterbatch is the key component for the regulation of color masterbatch melt flow index, helps to achieve comprehensive, convenient and effective recovery and reuse of the waste high density polyethylene plastic. The coextruded plastic wood composite prepared by the invention has the advantages of low price, similarity to the natural wood and good user experience. The invention also provides a preparation method of the full-body graining polyethylene plastic wood composite, and the method is simple in equipment, high in automation degree and easy to large scale production.

Description

technical field [0001] The invention relates to the field of plastic-wood profiles, in particular to a whole-body imitation wood-grain polyethylene plastic-wood profile and a preparation method thereof. Background technique [0002] Polyethylene plastic wood profile products have developed rapidly in my country in recent years. Polyethylene plastic-wood products replace logs and reduce deforestation. They are green and environmentally friendly energy-saving and consumption-reducing products, and are gradually loved by the general public. However, the color of polyethylene wood products is mainly brown, teak, chocolate and other pure single colors; the surface of the product is polished, brushed, and hot-pressed with metal steel rollers, so that the products produced in this way have a single color, dull texture, and no log texture. And texture, it is difficult to compare with real logs in appearance and sense, and the user experience is poor. Use polyethylene waste plastic...
