Flame-retardant roll type curtain and production process thereof

Abstract

The invention relates to a flame-retardant material and a production process thereof, in particular to a flame-retardant roll type curtain and a production process thereof. Both the front and the back of the curtain fabric of the flame-retardant roll type curtain have a colorless and transparent flame-retardant coating. Slurry for the flame-retardant coating comprises the following components in percentage by mass: 10 to 40 percent of environmentally-friendly flame-retardant agent, 10 to 45 percent of environmentally-friendly nanometer adhesive, 2 to 5 percent of thickener and 45 to 78 percent of water. The roll type curtain has an excellent flame-retardant property, and a GB5455 vertical burning method is adopted for an flame-retardant test, and the flame-retardant property of the roll type curtain reaches above B2 level when assessed according to 6817591; the curtain is free of solvent volatilization pollution, formaldehyde, alkylphenol ethoxylates (APEO), or toxic gas released in the process of burning; the production process is simple, can realize continuous production without any special equipment, and also can be combined with other processes for one-step implementation.

Description

technical field [0001] The invention relates to the technical field of flame-retardant materials and their production techniques, in particular to a flame-retardant roll-up curtain and its production techniques. Background technique [0002] With the improvement of people's awareness of fire protection, interior decoration materials are required to be fire-resistant and flame-retardant. The general technology is to add flame retardant materials on the base material as decorative boards and so on. Like curtains and wallpapers, a layer of fireproof material is generally impregnated on the base material. [0003] In recent years, the flame-retardant technology includes composite spinning and grafting technology, halogen-based and phosphorus-based copolyester fibers, and flame-retardant finishing of fabrics. Composite spinning and post-graft copolymerization require high technical conditions and high production costs, so they are not commonly used. Although the flame retardan...

Problems solved by technology

It has been reported that inorganic compounds are used for coating, and it is also reported that multi-layer fabrics (including metal layers and heat insulation layers) are used to shield flames (such as patent CN201015909). Such a treatment method will inevitably increase the thickness of the fabric and change the shading properties. Roll-up curtains that require proper light transmission are not suitable, and the processing technology of multi-layer fabrics is complicated, and the investment in equipment is large, so the production cost is also increased a lot
