Problems solved by technology

[0004] Although the existing PVC floor has many functions, and has made a major breakthrough in formula and technology, there are still some deficiencies, and it cannot simultaneously have the functions of flame retardancy, antibacterial, antistatic, antiaging, etc.
For example, the Chinese invention patent (patent number 200610041030.2, application date 2006 / 7 / 15) discloses a wear-resistant wood-plastic floor and its production process. , but does not have the characteristics of antibacterial and anti-aging; Chinese invention patent (patent number 200710039105.8, application date 2007 / 4 / 4) discloses a manufacturing method of plastic imitation wood floor, although the floor has anti-aging, anti-skid and other properties , but does not have flame retardant, antibacterial, antistatic properties; Chinese invention patent (patent number 200910111538.9, application date 2009 / 4 / 23) discloses high elastic wear-resistant sports floor surface material and its preparation method. Although the floor has high Elasticity, abrasion resistance, flame retardancy and mildew resistance, but no flame retardancy and anti-aging properties

Abstract

The invention provides a PVC (polyvinyl chloride) micro-foam floor and a preparation method thereof. The PVC micro-foam floor comprises the following components in parts by weight: 120-150 parts of PVC resin, 40-80 parts of diatomite, 10-20 parts of plant fiber, 5-10 parts of plasticizer, 1-5 parts of heat stabilizer, 0.5-3 parts of lubricating agent, 0.7-2 parts of anti-impact modifier, 1.5-3.5 parts of antioxidant, 0.5-1.2 parts of foaming agent, 3-7 parts of flame retardant and 2-7 parts of antibacterial agent. The PVC micro-foam floor provided by the invention has the advantages of high impact strength, tensile strength, tear strength and compressive strength, good wear resistance, water resistance and weather resistance, flame-retardant, anti-bacterial, anti-static and anti-aging effects, capability of keeping the color of the floor unchanged for a long time, and durability.

Description

technical field [0001] The invention relates to a floor and a preparation method thereof, in particular to a PVC microfoam floor and a preparation method thereof. Background technique [0002] Flooring has been widely used in indoor and outdoor decoration, and the flooring currently used mainly includes solid wood flooring, composite flooring and plastic flooring. Solid wood floor needs to consume a large amount of wood, which is expensive, and its water resistance is poor, easy to crack and warp; composite floor has poor water resistance and wear resistance, and will warp after being exposed to water, resulting in poor decorative effect. Therefore, solid wood flooring and composite flooring can only be used for indoor decoration, not for outdoor decoration. The plastic floor can be used not only for indoor decoration, but also for outdoor decoration, especially the PVC floor in the plastic floor, which has a very wide range of applications. [0003] PVC floor is a new typ...
