Problems solved by technology

[0004] At present, in the manufacturing method of melt-blown nonwoven materials on the market, when the material is mixed, melted and stirred, the stirring effect is poor, resulting in uneven distribution between the components, which affects the melt-blown effect; In the process, because the temperature of the fiber will drop suddenly when it leaves the die, if the temperature drops under the action of traction, the continuity of the fiber will be reduced, which will affect the forming effect of the melt-blown cloth, and it will also be in the melt-blown die. The outlet of the outlet forms a node, which affects the subsequent processing operations

Embodiment Construction

[0029] refer to Figure 1 to Figure 2 An embodiment of a method for manufacturing a melt-blown nonwoven material of the present invention will be further described.

[0030] For ease of description, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the position of one element or feature shown in the figures relative to another element or feature. relation. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative specifica...

Abstract

The invention discloses a method for manufacturing a melt-blown nonwoven material, and aims to provide a method for manufacturing a melt-blown nonwoven material with good molding effect, strong structural stability and strong fiber continuity. Select, set the mixed material to polypropylene, fluoropolymer and electret, control the forming and electret effect of the melt-blown nonwoven material fiber, improve the overall forming effect of the melt-blown cloth, and have strong practicability. And in order to improve the molding effect of the electret masterbatch, by taking 50-80 parts of polypropylene resin in 200 parts of polypropylene resin and fluoropolymer, electret, lubricant and antioxidant after uniform blending, when extruding , repeated uniform stirring to improve the effect of uniform distribution of fluorine-containing polymers and electrets, ensuring good molding and electret effects, strong practicability, and simple structure. The present invention is suitable for the technical field of medical supplies manufacturing .

Description

technical field [0001] The invention relates to the technical field of manufacturing medical supplies, more specifically, it relates to a method for manufacturing melt-blown nonwoven materials. Background technique [0002] Traditional melt-blown nonwoven materials need to ensure the surface roughness of the fibers, the stability of the crystal structure and the size of the fiber web, and the uniform stability of the electret. [0003] The traditional manufacturing method of melt-blown nonwoven materials needs to select the material first, then mix some materials, select the electret masterbatch, and finally mix the electret masterbatch with the remaining materials to form Melt blown polypropylene nonwoven. [0004] At present, in the manufacturing method of melt-blown nonwoven materials on the market, when the material is mixed, melted and stirred, the stirring effect is poor, resulting in uneven distribution between the components, which affects the melt-blown effect; In...
