Waterproof flame-retardant covering cloth

Abstract

The invention provides a waterproof flame-retardant covering cloth with excellent waterproof property, flame retardance, air permeability and the like. The waterproof flame-retardant covering cloth comprises a base fabric layer, wherein the base fabric layer is formed by interweaving cotton and linen blend fiber, polyester fiber and spandex, a waterproof layer is arranged on one side of the base fabric layer, and a flame-retardant layer is arranged on the other side of the base fabric layer; a first wear-resistant layer is arranged on the side, back to the base fabric layer, of the waterprooflayer, a second wear-resistant layer is arranged on the side, back to the base fabric layer, of the flame-retardant layer, and a polyvinyl chloride film layer in which a plurality of fine pores are formed is arranged on the surface of the waterproof layer; the flame-retardant layer is a flame-retardant fiber cloth layer which is made from glass fiber, and the first wear-resistant layer and the second wear-resistant layer are both polyester resin wear-resistant coatings. According to the waterproof flame-retardant covering cloth, waterproof and flame-retardant functions can be achieved by arranging the waterproof layer and the flame-retardant layer on both sides of the base fabric layer separately, and a wear-resistant function is achieved through the arrangement of the wear-resistant layers on the outermost layers; through the arrangement of the fine pores on the surface of the waterproof layer, waterproof and air permeability effects are achieved at the same time, so the waterproof flame-retardant covering cloth is very suitable for covering and protecting special goods.

Description

technical field [0001] The invention relates to a fabric, in particular to a waterproof and flame-retardant tarpaulin. Background technique [0002] The tarpaulin has good waterproof and mildew resistance, high tensile strength, acid and alkali corrosion resistance, easy to wash and fold, and can be used for covering goods in rainy days or building outdoor tents, such as covering goods on trains, cars and ships , Covering of temporary stacked goods, etc. [0003] The existing common tarpaulin is in the form of a layer of base cloth coated on both sides. This tarpaulin has the following problems: thin thickness, poor tensile strength and tear resistance, and general waterproof effect. There is also the form of multi-layer multi-film, which has the following problems: heavy weight and poor air permeability. None of the above tarpaulins has good flame retardancy, which makes it unable to meet some special applications in reality. For example, many goods are extremely sensitiv...

Problems solved by technology

[0003] The existing common tarpaulin is in the form of a layer of base cloth coated on both sides. This kind of tarpaulin has the following problems: thin thickness, poor tensile and tear resistance, and general waterproof effect

There are also multi-layer and multi-film forms. This tarpaulin has the following problems: heavy weight, poor air permeability

None of the above tarpaulins has good flame retardancy, which makes it unable to meet some special applications in reality. For example, many goods are extremely sensitive to the surrounding environment. A lot of water vapor may also react. This kind of goods is generally stored in a cool, dry and ventilated warehouse, but sometimes it has to be temporarily placed in the open air during transportation, and ordinary tarpaulins cannot cover and protect such goods well.
