Abstract

The invention discloses an anti-bacterial mould-proof floor film and a preparation technology thereof. The floor film is prepared from the following raw materials in parts by weight: 80-100 parts of PVC resin powder, 2.5-4 parts of a silver-carrying nano TiO2 antibacterial agent, 2-3 parts of a mildew preventive, 12-16 parts of epoxidized soybean oil, 5-7 parts of a plasticizer and 3-5 parts of a stabilizer. The raw materials of the floor film are added with the silver-carrying nano TiO2 antibacterial agent with good antibacterial property, breeding of microorganisms such as bacteria can be effectively inhibited, and a floor is prevented from being eroded by the bacteria; and the mildew preventive in the raw materials is a compound of pyridine sulfur-copper-zinc and N-octyl-4-isothiazolin-3-one, can inhibit growth of gram positive and negative bacteria, penicillium purpurogenum and aspergillus fumigatus and has excellent mildew-proof property.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antibacterial and mildew-proof floor film and a preparation process thereof. Background technique [0002] Polyvinyl chloride plastic floor film is a kind of plastic decoration material developed earlier. It is an economical floor material with relatively low price. As a new type of decorative material, polyvinyl chloride plastic flooring has been increasingly valued by the market, and has gradually become an important floor decorative material in interior decoration. Because it has many advantages such as ultra-light and ultra-thin, wear-resistant, scratch-resistant, high elasticity, impact resistance, non-slip, sound-absorbing, small seams and seamless welding, fast installation and construction, and a wide variety of designs and colors. For example, from the perspective of wear resistance and scratch resistance, the general wear resistance of a good PVC floor f...
