Abstract
The invention relates to the technical field of carpets, and particularly discloses a flame-retardant carpet film, a flame-retardant carpet and a manufacturing method of the flame-retardant carpet. The flame-retardant carpet film is prepared from, by weight, 3%-6% of color master batch, 52%-70% of polyethylene, 20%-30% of LLDPE metallocene, 3%-6% of EVA ethylene-vinyl acetate copolymer and 2%-10%of a compound flame retardant; the flame-retardant carpet comprises a foaming layer and the flame-retardant carpet film, A facing layer is compounded on the surface of the foaming layer; the preparation method comprises the following steps: step 1, weighing the components according to the formula, adding the components into a dispersion machine, and mixing for 2040 minutes; step 2, heating the material in the step 1 to 230-240 DEG C, and melting for 3-4h; step 3, tape casting; step 4, cooling and molding to obtain the flame-retardant carpet film; 5, compounding the flame-retardant carpet filmon the surface of the foaming layer; and step 6, compounding a facing layer on the surface of the flame-retardant carpet film to obtain a target product. The flame-retardant carpet has the advantagesof being good in flame retardant property and capable of reducing fire hazards.
Description
technical field [0001] The application relates to the field of carpets, in particular to a flame-retardant carpet film, a flame-retardant carpet and a manufacturing method thereof. Background technique [0002] Carpet is a floor covering made of natural fibers or chemical synthetic fibers. It is one of the arts and crafts categories with a long history and tradition in the world. It covers the ground of residences, hotels, hotels, conference rooms, entertainment venues, gymnasiums, exhibition halls, vehicles, ships, aircraft, etc., and has the functions of reducing noise and heat insulation. And decorative effects to improve the feeling of feet, prevent slipping, and prevent air pollution. The internal use area of the house is the kitchen, bedroom, bedside, coffee table sofa, bathroom, and living room. [0003] During the use of the carpet in the house, when a fire source occurs in the house, the carpet will also burn, which will aggravate the fire and cause serious prop...
