Problems solved by technology

[0003] With the improvement of people's living standards, people's requirements for non-woven fabrics are getting higher and higher. However, since the non-woven fabrics on the market are made of hydrocarbon materials, they are easy to cause combustion and cannot meet the needs of safety and fire prevention.

preparation example 1-3

[0036] A kind of modified montmorillonite of preparation example 1-3, its each raw material and each raw material consumption are as shown in table 1, and its preparation step is as follows:

[0037] T1. The montmorillonite is prepared into a suspension with a mass fraction of 7%, heated to 60°C, and fully stirred;

[0038] T2, then add 10% dioctadecyl dimethyl ammonium chloride solution to the solution obtained in T1, continue stirring at constant temperature for 6h, filter the reactant with suction to obtain a white precipitate, wash the precipitate with a hot ethanol aqueous solution;

[0039] T3. The material obtained in T2 is vacuum-dried at 65° C. for 48 hours, and finally ground to obtain modified montmorillonite.

Embodiment

[0043] A kind of flame retardant and antibacterial non-woven fabric of embodiment 1-5, each raw material and each raw material consumption are as shown in Table 3, and its preparation steps are as follows:

[0044] S1. Weigh each raw material according to the raw materials, first put the modified montmorillonite and brominated epoxy resin into the mixer and mix them uniformly, and then pour the polypropylene and the slip agent into the mixer, and mix uniform to obtain mixed raw materials;

[0045] S2. The mixed raw materials are transported into the screw extruder, heated to a molten state, and extruded by bolts to obtain molten slurry;

[0046] S3. The molten slurry is added to the wire drawing machine, and the wire is drawn through the spinneret hole to form a fiber web;

[0047] S4, hot rolling the obtained fiber web through a hot rolling mill to form a non-woven fabric, the pressure of the hot rolling mill is 3.7N, the suction air temperature is 700°C, the cold air temper...

Embodiment 6

[0052] A flame-retardant and antibacterial non-woven fabric is different from Example 3 in that the added modified montmorillonite is from Preparation Example 2, and the remaining steps are the same as those in Example 3.

Abstract

The invention relates to the field of non-woven fabrics, in particular to a flame-retardant antibacterial non-woven fabric and a preparation method thereof. The flame-retardant antibacterial non-woven fabric is prepared from the following raw materials in parts by weight: 60 to 75 parts of polypropylene, 5 to 10 parts of slipping agent, 5 to 15 parts of brominated epoxy resin and 5 to 10 parts of modified montmorillonite. The flame-retardant antibacterial non-woven fabric disclosed by the invention has relatively high flame retardance, antibacterial property and breaking strength.

Description

technical field [0001] The present application relates to the field of non-woven fabrics, and more particularly, to a flame-retardant and antibacterial non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are fabrics formed without spinning and weaving, but by orienting or randomly arranging textile staple fibers or filaments to form a web structure , and then reinforced by mechanical, thermal bonding or chemical methods, non-woven fabrics are widely used in various fields because of their flexibility, lightness, non-toxic and tasteless, low price, and recyclability. [0003] With the improvement of people's living standards, people's requirements for non-woven fabrics are getting higher and higher. However, because the non-woven fabrics on the market are made of hydrocarbon materials, it is easy to cause combustion and cannot meet th...
