Flame-retardant transparent floor film and production technology thereof

Abstract

The invention relates to a flame-retardant transparent floor film and a production technology thereof. The flame-retardant transparent floor film is prepared by treating the following main raw materials in parts by weight: 100 parts of PVC (Poly Vinyl Chloride) resin powder, 15 to 30 parts of a main plasticizer, 4 to 8 parts of a fire-retardant plasticizer, 4 to 6 parts of a stabilizer, 6 to 12 parts of an inorganic filler, and 2 to 4 parts of epoxidized soybean oil by a PVC die rolling technology. By adopting the flame-retardant transparent floor film and the production technology thereof, the conflict between the flame retardant performance, the transparence and the jet-printing performance is solved; the inorganic fillers are adopted, thus micromolecules separated by the liquid fire-retardant plasticizers are easily absorbed, and ideal transparence and the jet-printing performance can be provided for the product under efficient flame retardant performance; in addition, the generation of phenomena of wheel adhering, albinism and hard coiling can be effectively avoided by utilizing the flame-retardant transparent floor film; and simultaneously, the flame-retardant transparent floor film is excellent in wear resistance.

Description

technical field [0001] The invention belongs to the field of decoration materials, and in particular relates to a flame-retardant transparent floor film for modern decoration floors and a production 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 resis...

Problems solved by technology

[0003] Since PVC floor film is used as a building material, the country has issued a number of standards to regulate and restrict, and has made clear regulations on the flame-retardant performance of flame-retardant and fire-resistant floor materials. The flame-retardant and fire-resistant performance is the primary indicator related to the safety of life and property. Therefore, the PVC floor film should be endowed with flame retardancy during the manufacturing process, but there is a great contradiction between the flame retardancy, transparency and inkjet performance of the traditional flame retardant floor film. For example, in order to endow the PVC floor film with flame retardancy, it must Adding powder or liquid flame retardants, however, adding powder flame retardants will affect the luminous flux of the film due to the existence of flame retardants, and then affect the transparency of the product. If the transparency of the product is low, the colorful paint on the bottom Pattern, the visual effect will be greatly discounted after a layer of PVC floor film with low transparency, which seriously affects the aesthetics of the product; in addition, although the addition of liquid flame retardant will not affect the transparency of the product, it is easy to separate out from the PVC floor film And reduce the surface tension of the film so that the inkjet performance (ink absorption) of the product is greatly reduced, which reduces the clarity of the product's inkjet pattern; and when the traditional transparent film processing process is used, it is easy to appear sticking wheel phenomenon; In the process of stretching, it is easy to appear serious whitening and affect the apparent transparency, and it is easy to appear difficult to coil, etc.
