Embodiment 1

[0019] Embodiment 1: first prepare the concentration in the dipping tank and be the ammonium polyphosphate (APP) aqueous solution of 35%, then with anti-adhesive method polypropylene non-woven fabric impregnated 5min in flame retardant; The woven fabric is dried in a high-temperature oven at 50°C; the dried flame-retardant polypropylene non-woven fabric is sent to a winder for winding to obtain a finished product. According to the national standard GB5454-85, the oxygen index of the flame-retardant non-woven fabric measured by the HC-1 oxygen index tester is 27%.

Embodiment 2

[0020] Example 2: First prepare a concentration of 10% triisopropyl phosphate aqueous solution in the dipping tank, then immerse the anti-adhesive polypropylene non-woven fabric in the flame retardant for 30min; the polypropylene impregnated with the flame retardant The non-woven fabric is dried in a high-temperature oven at 65°C; the flame-retardant polypropylene non-woven fabric after drying is sent to a winder, and the finished product is wound. Its oxygen index measured by the method of Example 1 is 25%.

Embodiment 3

[0021] Embodiment 3: first prepare the melamine aqueous solution that concentration is 15% in the dipping tank, then impregnate the non-woven polypropylene non-woven fabric of anti-adhesive method in flame retardant for 25min; soak the polypropylene non-woven fabric of flame retardant at high temperature Dry in an oven at 40°C; send the dried flame-retardant polypropylene non-woven fabric to a winder for winding to obtain a finished product. Its oxygen index measured by the method of Example 1 is 29%.

Abstract

The invention relates to a non-woven fabric, in particular to a fire-retardant polypropylene non-woven fabric and a preparation method thereof. The preparation method comprises the following steps: using a polypropylene non-woven fabric as a substrate; covering a fire-retardant layer formed by a fire retardant on the surface of the substrate, wherein the fire retardant is an inorganic phosphorus fire retardant, an organic phosphorus fire retardant, a nitrogen-contained fire retardant or an intumescent fire retardant; impregnating the polypropylene non-woven fabric in a fire retardant aqueous solution with the concentration of 10-40 percent for 5-30 minutes; and then, drying at 40-65 DEG C, coiling and packaging. The environment-friendly fire retardant is adopted for the fire-retardant treatment of the polypropylene non-woven fabric so that the prepared fire retardant non-woven fabric has high oxygen index, good fire-retardant performance, flexibility, light texture, little residentialdeformation, favorable mechanical performance, simple and practical preparation process, good product performance, low cost and strong economy and practical values.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a flame-retardant polypropylene non-woven fabric with a flame-retardant function and a preparation method thereof. Background technique [0002] Polypropylene (PP) non-woven fabric (polypropylene non-woven fabric) is thin and light, and feels good; it is porous, the product has good air permeability, and it is easy to keep the cloth surface dry; it is non-toxic, odorless, does not irritate human skin, and is resistant to acid , Alkali has excellent durability. At the same time, due to the weak chemical structure of polypropylene, the molecular chain can be easily broken, so that it can be effectively degraded, and enter the next environmental cycle in a non-toxic form. Therefore, polypropylene non-woven fabrics are environmentally friendly materials. Has been widely used. However, polypropylene is a hydrocarbon material with a low oxygen index of only 17.4. It is easy to burn, and the heat...
