Abstract
The invention discloses an anti-skid laminated non-woven fabric, which is of a double-layer structure, wherein the upper layer is a film layer formed from low-density polyethylene, polypropylene, polybutylene and auxiliaries by blending, melting and extrusion; and the bottom layer is a spunlace non-woven fabric. Meanwhile, the invention further discloses a method for preparing the non-woven fabric, which comprises the steps of fabric guiding, feeding, melted extrusion by a screw, lamination by a die head and winding, wherein raw materials and auxiliaries, used in the above steps, are ought to be blended according to a certain mass percent; in the step of melted extrusion by the screw, each section of the screw is at a temperature range from 140 DEG C to 290 DEG C and a filter screen is at a temperature range from 300 DEG C to 320 DEG C; and in the step of lamination by the die head, each section of the die head is at a temperature range from 300 DEG C to 320 DEG C. The anti-skid laminated non-woven fabric is high in strength, water absorbability, barrier property and hydrostatic pressure resistance, and is particularly strong in anti-skid capability.
Description
Technical field
The present invention relates to a kind of nonwoven, particularly a kind of anti-skidding pouring film nonwoven, and the preparation method of this anti-skidding pouring film nonwoven.
Background technology
Drenching the film nonwoven, on nonwoven, coat layer of plastic film exactly, generally all is that heat becomes the plastic coat of hot melt state on nonwoven, to cool off the product that forms.Be generally materials at two layers, base cloth is in the majority with polypropylene spun sticky cloth, spunlace non-woven cloth, has fabulous feel; Polyethylene film then has outstanding tension and extension property, and is not perishable; Drench the film nonwoven and combined above-mentioned two kinds of advantages, have advantages such as peel strength is good, high-tenacity, high-hydroscopicity, high barrier, high hydrostatic pressure resistant, be widely used in every field.But the pouring film nonwoven that is used for places such as medical sick bed requires to have certain non-skid property, but existing pouring film nonwoven, its skidproof effect can't reach requirement.Therefore need a kind of novel pouring film nonwoven that can address the above problem now.
Summary of the invention
The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of high-tenacity, high-hydroscopicity, high barrier, pouring film nonwoven that high hydrostatic pressure resistant, particularly skid resistance are stronger.
Technical solution of the present invention is: a kind of anti-skidding pouring film nonwoven; It is characterized in that: described anti-skidding pouring film nonwoven is a double-decker; The upper strata is the thin layer after low density polyethylene (LDPE), polypropylene, polybutene and auxiliary agent blended melting are extruded, and bottom is the spunlace non-woven cloth layer.
The production method for preparing above-mentioned anti-skidding pouring film nonwoven comprises and draws cloth, material loading, screw rod melt extruded, die head pouring film and coiling step, it is characterized in that:
In a, the material loading step; After raw material and auxiliary agent mixed, deliver among the hopper through sucktion fan, wherein raw material is made up of low density polyethylene (LDPE), polypropylene, polybutene; Auxiliary agent then is made up of polyisobutene and softening agent as antilubricant, and its mass percent is:
Low density polyethylene (LDPE): polypropylene: polybutene: polyisobutene: softening agent
40-70 : 5-10 : 4-25 : 1-5 : 5-30
And the mass fraction of polybutene is 4-5 times of the antilubricant mass fraction,
In b, the screw rod melt extruded step, it is 140-290 ℃ that its screw rod is respectively distinguished temperature range, and the screen pack temperature range is 300-320 ℃,
C, die head drench in the film step, and it is 300-320 ℃ that die head is respectively distinguished temperature range.
The present invention compares with prior art, has following advantage:
The anti-skidding pouring film nonwoven of this kind of version adopts spunlace non-woven cloth as bottom, the top layer then be polyethylene, polypropylene, polybutene in the presence of auxiliary agent, blended melting is extruded the film that obtains; And adopting special proportioning raw materials and method to process, the product that obtains has the following advantages: at first, polyethylene, polypropylene, polybutene and auxiliary agent blend have good overlap joint viscosity and peel adhesion, the steady quality of product; Secondly, product had both had the spunlace non-woven cloth soft hand feeling as basic unit, advantages such as good heat insulating ability, good waterproof performance, characteristics such as the peel strength that also has film simultaneously is good, coefficient of friction is high, and skid resistance is good, and viscosity is little; And the interpolation of modified additive (softening agent) strengthens fluidity of molten, and drenching does not have uneven or broken abdomen phenomenon in the membrane process, production process is operated easily.Therefore we can say that this anti-skidding pouring film nonwoven and its production method possess multiple advantage, be particularly suitable for applying in the art that its market prospects are very wide.
The specific embodiment
The specific embodiment of the present invention is described below.
A kind of anti-skidding pouring film nonwoven, this anti-skidding pouring film nonwoven is a double-decker, and the upper strata is a thin layer, and this thin layer is to be extruded formedly by low density polyethylene (LDPE), polypropylene, polybutene and auxiliary agent blended melting, and its bottom is the spunlace non-woven cloth layer.
The production method for preparing above-mentioned anti-skidding pouring film nonwoven comprises and draws cloth, material loading, screw rod melt extruded, die head pouring film and coiling step, wherein:
In the material loading step; After raw material and auxiliary agent mixed; Deliver among the hopper through sucktion fan; Wherein raw material is made up of low density polyethylene (LDPE), polypropylene, polybutene, and auxiliary agent then is made up of polyisobutene and softening agent as antilubricant, and raw material and auxiliary agent are according to the certain quality percentage mix; And in screw rod melt extruded step, the temperature and the screen pack temperature in each district of screw rod all should be within the specific limits; Drench in the film step at die head, the temperature in each district of die head also should be within the specific limits.
Specific embodiment:
Raw material mixes according to following proportioning with auxiliary agent:
Low density polyethylene (LDPE): polypropylene: polybutene: polyisobutene: softening agent
40-70 : 5-10 : 4-25 : 1-5 : 5-30
And the mass fraction of polybutene be polyisobutene mass fraction 4-5 doubly;
In the screw rod melt extruded step, it is 140-290 ℃ that its screw rod is respectively distinguished temperature range, and the screen pack temperature range is 300-320 ℃, and die head drenches in the film step, and it is 300-320 ℃ that die head is respectively distinguished temperature range.
