Flame-retardant textile and flame-retardant adhesive for flame-retardant textile and preparation method of flame-retardant adhesive

Abstract

The invention discloses a flame-retardant textile and a flame-retardant adhesive for the flame-retardant textile and a preparation method of the flame-retardant adhesive. The flame-retardant adhesive is prepared from a waterborne white modified emulsion, a water-soluble polymer thickener, a foaming agent, a foam stabilizer, zinc borate, a halogen-free phosphorous nitrogen ammonia-based flame-retardant powder and softened water; the method comprises the steps of weighing a certain amount of softened water and waterborne white modified emulsion in a stirring tank; fully stirring, sequentially adding the foaming agent and the foam stabilizer; weighing the zinc borate, slowly and uniformly adding the halogen-free phosphorous nitrogen ammonia-based flame-retardant powder to a mixture, and stirring while adding; and adding the water-soluble polymer thickener, fully stirring, filtering and discharging to obtain the flame-retardant adhesive. By adopting the halogen-free phosphorous nitrogen ammonia-based flame-retardant powder, the flame-retardant adhesive does not contain halogen and does not cause secondary pollution to the air environment during combustion; since no formaldehyde is added, a product is more environment-friendly; the zinc borate plays a flame-retardant synergistic role as an auxiliary flame retardant; and the flame-retardant adhesive has the advantages of being simple in preparation technology, good in use effect and low in cost.

Description

technical field [0001] The invention relates to the technical field of flame-retardant fabrics, in particular to a flame-retardant fabric, a flame-retardant glue used for the flame-retardant fabric, and a preparation method of the flame-retardant glue. Background technique [0002] Flame-retardant fabrics refer to fabrics that can prevent themselves from being ignited or delay and stop burning when they come into contact with flames or hot objects. There are two types: fiber flame-retardant and finishing flame-retardant. Fiber flame retardant means that when preparing polyester fiber or viscose fiber, by adding a flame retardant in the spinning solution, the final fiber itself has flame retardant properties, and the fabric fabric woven from the flame retardant fiber is With flame retardant function. Flame retardant after finishing refers to the production of non-woven fabrics or woven fabrics according to ordinary processes, and then impregnating and coating flame retardant...

Problems solved by technology

[0005] Although the technical solution disclosed in the above-mentioned invention patent application can make the fiberboard have a certain flame retardant performance, it uses formaldehyde, organic solvents such as isopropanol and ethanol, and the toxic formaldehyde volatilizes during combustion, causing further air pollution. And raw materials such as isopropanol and ethanol are flammable solvents, which will directly affect the flame retardant performance of the flame retardant

Moreover, the production process of the flame retardant is relatively complicated, and the requirements for the viscosity, density, solid content and pH of the flame retardant itself are relatively high, and the production process is difficult to control.
