Abstract

The invention discloses an antibacterial polypropylene composite material. The composite material is prepared from polypropylene, an inorganic filler, a toughening agent, an antibacterial agent, an antioxidant, a light stabilizer, a coupling agent and a lubricant. The polypropylene composite material prepared by the invention is excellent in comprehensive performance; the density is 0.90-1.4 g / cm<3>; compared with a mud tile (the average density is 2.65 g / cm<3>), the weight is reduced by more than 45%; the prepared plastic tile is light in weight (easy to install and carry), corrosion-resistant, aging-resistant, not easy to break and the like; meanwhile, due to the characteristics of the polyolefin material, the prepared plastic tile also has the characteristics of low noise (low noise inrainy days), heat insulation, long service life, recyclability and the like; in addition, the prepared polypropylene composite material has an antibacterial effect, can reduce the corrosion of microorganisms and bacteria, and can also meet the requirements of novel roofs as gardens and vegetable gardens, so that the polypropylene composite material is a good substitute.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an antibacterial polypropylene composite material and a preparation method thereof, and also relates to a plastic tile. Background technique [0002] Generally speaking, the main parts of a building are defined as ground, facade (inner and outer walls) and roof, and each part has its corresponding building materials. For a long time, people's cognition of roofing materials has mostly focused on the understanding of tile materials. From the traditional point of view, the main function of roofing materials is waterproofing. Therefore, for thousands of years, in the north where water is scarce, most of the houses can be plastered with mud on sloped or flat roofs; while in the rainy south, closely arranged mud tiles need to be paved on the roof. For generations, mud tiles have been the only "coat" of the roof. [0003] However, when the concept of building energy savi...
