Abstract

The invention relates to a wallpaper and its technology, in particular to a polyethylene stone composite composite wallpaper and its manufacturing technology. Polyethylene stone synthetic wallpaper, which includes a mesh roving layer and a polyethylene stone powder polymer material layer; the polyethylene stone powder polymer material layer is composed of a masterbatch and an auxiliary agent, wherein the masterbatch is composed of the following components in mass percent: Polyethylene: 20-25%, CaCO3: 50-70%, talcum powder: 7-25%; additives are composed of the following components in mass percentage: composite coupling agent: 0.5-1%, dispersant: 0.5-1%, flame retardant: 0.5-1%, micro foaming agent: 0.1-1%, compatibilizer: 0.5-1%. The polyethylene stone composite wallpaper of the present invention has high strength, strong adhesion and flame retardant function. The manufacturing process adopted by the present invention has the advantages of simple process, low cost and high efficiency, and is suitable for large-scale industrial production.

Description

[0001] technical field [0002] The invention relates to a wallpaper and its technology, in particular to a polyethylene stone composite composite wallpaper and its manufacturing technology. Background technique [0003] Paper is one of China's four great inventions. The raw materials of traditional paper are mainly plant fibers such as wood. With the introduction of the national forest protection policy and the implementation of the ban on logging, the raw materials for papermaking can only be maintained by imported wood pulp. The traditional paper production process produces a large amount of waste water and other three wastes, which seriously pollutes the environment and is extremely difficult to treat. Traditional paper is not resistant to moisture and corrosion. Various physical and mechanical properties and dimensional stability are poor, which can no longer meet the special requirements of many paper fields. Paper production and development require innovation. ...
