Abstract

The invention discloses an environmentally-friendly flame-retardant floor leather and a production method thereof. The floor leather successively comprises a cloth base layer, a flame-retardant layerand a non-slip wear-resistant layer. The flame-retardant layer comprises the following raw materials by mass: 43.92-53.68% of polyvinyl chloride, 26.02-31.80% of dioctyl phthalate, 2.20-2.68% of dioctyl sebacate, 4.12-5.04% of tin methyl sulfonate, 5.50-6.72% of a fire retardant, 3.19-3.89% of a smoke suppressor, 3.78-4.62% of a PVC processing aid and 1.28-1.56% of a flavoring agent. The production method comprises the following concrete production steps: (1) mixing the raw materials of the flame-retardant layer; (2) carrying out extrusion molding to complete the preparation of the flame-retardant layer; (3) during extrusion molding of a semi-finished floor leather product in the step (2), spreading a layer of colored-spot quartz sand on one surface of the semi-finished floor leather product, blowing hot air with a hot-air blower to realize fusing and then carrying out embossing and cooling molding so as to complete the preparation of the non-slip wear-resistant layer; and (4) laminating the other surface of the semi-finished floor leather product obtained in the step (3) with the composite cloth base layer so as to obtain a floor leather product. According to the invention, the flame retardant properties of the floor leather are allowed to accord with standard requirements prescribed in JT / T1095-2016 through the improvement of the formula of the flame-retardant layer.

Description

technical field [0001] The invention relates to the field of floor leather, in particular to an environment-friendly flame-retardant floor leather and a production method thereof. Background technique [0002] As society pays more and more attention to personal safety, the safety of passenger cars, a vehicle with a large passenger capacity, has received widespread attention. There are many types and large quantities of interior materials in passenger cars. Once a fire breaks out, it is easy to produce molten drippings, accompanied by a large amount of smoke, which will cause oxygen deficiency and suffocation of passengers in a short time. Therefore, not only the interior materials of automobiles The degree of flame retardancy, including the degree of smoke after burning, should have higher requirements. At present, the flame retardant requirements of passenger car interior materials only refer to the national mandatory standard GB8410-2006 to control horizontal combustion, ...
