Abstract

The invention discloses a high-filling heatproof polypropylene composite material used for environmental protection wallpaper and a preparation method thereof, the composite material is prepared by 15-40 parts of polypropylene, 60-85 parts of inorganic powder, 0.1-0.6 parts of coupling agent, 0.1-0.4 parts of anti-oxidant, 0.1-0.5 parts of lubricant and 0-2 parts of other auxiliary agents according to weight. The composite material has the advantages of high filler content, high applicable temperature and green environmental protection, can replace the plant fiber to produce the wallpaper, and reduces the tree felling; the composite material can prepare a lightweight, heatproof and environmental protection wallpaper base layer through film blowing; and the material preparation technology has the advantages of controllable process, low production cost and no secondary pollution.

Description

[0001] technical field [0002] The invention belongs to the technical field of polymer composite materials, and in particular relates to a high-filling, heat-resistant and environmentally friendly polypropylene composite material for wallpaper. [0003] technical background [0004] Wall decoration wallpaper is a commonly used wall decoration material for homes and hotels. At present, the widely used decorative wallpaper substrates are mainly divided into three categories: the first is the wallpaper substrate produced from paper pulp and wood pulp. Natural resources such as trees consume a lot of water in the papermaking process; the other is to apply a layer of polyvinyl chloride (PVC) emulsion on the paper surface of the base paper, and then prepare the wallpaper base layer by scraping and embossing. However, since the PVC material itself is hard and difficult to color, it is necessary to add a large amount of dioctyl phthalate (DOP) plasticizers and dyeing aids when ...
