Flame-retardant novel material carpet

Abstract

The invention provides a flame-retardant novel material carpet which comprises a polyvinyl alcohol flame-retardant film and a polyvinyl alcohol flame-retardant non-woven fabric. The polyvinyl alcoholflame-retardant film is adhered with the polyvinyl alcohol flame-retardant non-woven fabric by flame-retardant polyvinyl alcohol glue; the thickness of the polyvinyl alcohol flame-retardant film is 30-50 micrometers; the gram weight range of the polyvinyl alcohol flame-retardant non-woven fabric is 45-130 grams / square meter; the dosage of the flame-retardant polyvinyl alcohol glue is 5-30 grams / square meter; printed layers are arranged on the outer surface of the polyvinyl alcohol flame-retardant non-woven fabric, and patterns such as arrow marks or trademark patterns can be printed; the polyvinyl alcohol flame-retardant non-woven fabric is preferably a polyvinyl alcohol flame-retardant spunlace non-woven fabric; raw materials in coating formulas for the printed layers include, by weight,30-50 parts of acrylic acid modified polyurethane emulsion, 10-20 parts of silica sol, 20 parts of water, 10 parts of ethyl alcohol, 0.5 part of leveling agents and 0.5 part of defoaming agents.

Description

technical field [0001] The invention relates to the technical field of new material carpets, in particular to a disposable biodegradable flame-retardant new material carpet used in nuclear power plants. Background technique [0002] In the working environment of nuclear power plants, there may be some radioactive pollutants. People or equipment working and operating in this environment may be contaminated with radioactive pollutants. In order to prevent radioactive pollutants from contaminating the human body, nuclear power plants generally use disposable protective products to block or shield radioactive pollutants. [0003] In the maintenance of nuclear power plants, there are different types of vehicles that need to enter and exit the pollutant control area, and the entry and exit of these vehicles bring challenges to pollutant control. Usually the mode that people adopt is, pad disposable floor mat in the place that vehicle passes, to guarantee that vehicle tire does n...
