Abstract
The utility model provides a flame-retardant non-woven fabric, which comprises an upper surface, a lower surface and one or more non-woven fabric layers, wherein the upper surface and the lower surface are provided with flame-retardant layers; and the one or more non-woven fabric layers are positioned between the flame-retardant layers. A needed flame-retardant non-woven fabric is obtained by preparing a flame retardant and raw materials in a certain ratio, performing screw extruding, ejection and web formation on the raw materials, rolling into cloth with a rolling mill, performing a flame-retardant process and molding the non-woven fabric. The flame-retardant non-woven fabric disclosed by the utility model has a simple structure and high production efficiency, and waste of the flame retardant is avoided.
Description
Technical field
The utility model relates to the nonwoven fabric field, particularly a kind of flame retardant nonwoven fabric with fire-proof function.
Background technology
Nonwoven fabric is a kind of fabric that does not need to spin cotton and weave cloth and form, and it is that textile staple or long filament are carried out orientation or support row at random, forms fibre net structure, adopts methods such as mechanical, hot sticky or chemistry to reinforce then and forms.Compare with traditional woven, have that technological process is short, speed of production is fast, output height, characteristics such as cost is low, purposes is wide.Nonwoven fabric is widely used in medical and health use cloth, family decoration cloth, industrial cloth, agricultural fabric and is used to make space wadding etc. at present.The base stock of nonwoven fabric is mainly polypropylene (PP), and is light because it is thin, good hand touch; Have porous, good permeability easily keeps cloth cover dry and comfortable; Acid, alkali had excellent durability; And because polyacrylic chemical constitution is insecure, easily degraded also is a kind of environmentally friendly material, therefore, has obtained using widely.But, in some particular application, except general performance, also require nonwoven fabric to have good fire retardant performance, and because the raw material of nonwoven fabric such as polypropylene etc. are hydrocarbon class material, burning easily, present nonwoven fabric only comprises the nonwoven fabric surface layer of single or multiple lift, do not have flame-retardant layer, the application scenario of the fire protecting performance of therefore can not satisfying the demand.
The utility model content
At prior art problems, the utility model proposes the good flame retardant nonwoven fabric of a kind of fire line.
For reaching the purpose of this utility model, flame retardant nonwoven fabric of the present utility model comprises the nonwoven layer of the flame-retardant layer of upper and lower surface and the single or multiple lift between flame-retardant layer.
Preferably, flame retardant nonwoven fabric of the present utility model is by the fire retardant of preparing certain proportional quantity and raw material, spray, become net, milling train to be rolled into cloth, flame retarding process and nonwoven fabric moulding by the screw rod extruding of raw material then, finally obtain required flame retardant nonwoven fabric.
Preferably, the composition of described fire retardant comprises fire retardant, heat stabilizer, vector resin and auxiliary agent.
Preferably, the oxygen index (OI) of described nonwoven fabric is 40～45%.
The beneficial effects of the utility model are, on the surface of traditional nonwoven fabric flame-retardant layer are set, and can provide fire line good flame retardant nonwoven fabric, to satisfy the demand for the demanding application scenario of fire line.
Description of drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the utility model will become apparent.Wherein:
Figure 1 shows that the structural representation of flame retardant nonwoven fabric of the present utility model.
The specific embodiment
In conjunction with the manufacture craft of hydrophilic nonwoven fabrics of the present utility model shown in Figure 1, flame retardant nonwoven fabric of the present utility model comprises the upper and lower surface with flame-retardant layer 1 and the nonwoven layer 2 of the single or multiple lift between flame-retardant layer.
Flame retardant nonwoven fabric of the present utility model is by preparing the fire retardant and the nonwoven fabric raw material of constant weight proportioning, then raw material is sprayed by the screw rod extruding, become net, milling train flower roller is rolled into cloth, and the processing step of flame retarding process and last nonwoven fabric moulding makes.Wherein, the efficient flame retardant for textile of EPE that described fire retardant adopts Nantong IELTS flame-retarded technology Co., Ltd to produce, its composition comprises fire retardant, heat stabilizer, vector resin and auxiliary agent.Described flame retarding process is that fire retardant and the high purity water weight proportion according to 1: 250 is mixed, and is coated with (roller is tasted) on then, by being dried into cloth at a high speed.Finally make required flame retardant nonwoven fabric, after testing, its oxygen index (OI) is 43.1%.
The above only is a preferred embodiment of the present utility model; the utility model is not limited to described embodiment; those skilled in the art is not breaking away from spirit of the present utility model promptly openly in the scope; still can do some corrections or change, so rights protection scope of the present utility model is as the criterion with claims restricted portion.
Claims (1)
1. flame retardant nonwoven fabric is characterized in that: comprise the upper and lower surface with flame-retardant layer and the nonwoven layer of the single or multiple lift between flame-retardant layer.
