Abstract

The invention discloses a high-speed spinning non-woven fabric master batch, which comprises the following components, inorganic powder, a nonionic surface treating agent, a propylene lower polymer and other aids, wherein other aids include PE (Poly Ethylene) wax, PP (Propene Polymer) wax, a hyper dispersant, a free radical reversible stabilizer, a modified copolymerization monomer and high-melt-strength PP. The master batch can be added onto a high-speed spinning thread, is well dispersed with acrylic resin in a high-speed tracing process, and is free from a plasticizing phenomenon; in the high-speed tracing process, the melt strength is high, and a thread fracture phenomenon is avoided; and the problem of slurry dripping is avoided within a month (the adding proportion is 10 percent) in a high-speed spinning process.

Description

A kind of high speed spinning non-woven fabrics masterbatch

Technical field

The present invention relates to a kind of masterbatch, specifically high speed spinning non-woven fabrics masterbatch.

Background technology

At present visible or report nonwoven polypropylene fabric masterbatch can only be used for the lower spinning threadling of spinning speed, and general spinning speed is lower than 1500m/min, does not see that the masterbatch that can be fit to interpolation is arranged before and go up at high-speed spinning silk thread (reaching as high as 5000 m/min).Can add with existing masterbatch, drip slurry fracture of wire phenomenon, influence the quality and the efficient of spinning but can exist.

Summary of the invention

The objective of the invention is deficiency, provide that a kind of suitable high-speed spinning silk thread adds, can prevent to drip the high speed spinning non-woven fabrics masterbatch that slurry fracture of wire phenomenon occurs to the prior art existence.

For realizing the foregoing invention purpose, the technical scheme that the present invention adopts is a kind of high speed spinning non-woven fabrics masterbatch, comprises following composition: inorganic powder, non-ionic type surface treatment agent, propylene quasi-oligomer and other auxiliary agent; Wherein other auxiliary agent comprises PE wax, PP wax, hyper-dispersant, the reversible stablizer of radical, modified copolymer monomer and high fondant-strength PP.

The weight percent of said each composition is: inorganic powder: the non-ionic type surface treatment agent: the propylene quasi-oligomer: PE wax: PP wax: hyper-dispersant: the reversible stablizer of radical: modified copolymer monomer: high fondant-strength PP=100:0.4-0.9:0.8-1.2:2.0-3.0:1.5-2.5:0.5-1.0:0.2-0.6:0 .5-1.0:10-30.

Said inorganic powder is one or more the combination in lime carbonate, talcum powder, mica powder, zeyssatite, tiff, the zinc sulfide white, and blending ratio is looked the non-woven fabrics demand and decided.The general lime carbonate that uses needs certain rigid and hardness like fruit product, just mixes with lime carbonate and talcum powder, and blending ratio is looked the product requirements degree and decided; ,, mix just with lime carbonate and tiff (perhaps lime carbonate and zinc sulfide white) the having relatively high expectations of color like fruit product, high more to the color requirement, the ratio of lime carbonate is low more.Those skilled in the art can mix inorganic powder and replaces according to the demand of non-woven fabrics.

The present invention adopts ultra-fine or nano inorganic powder, with non-ionic type surface treatment agent and the multiple coating of propylene quasi-oligomer, reduces its surface energy, and is good with polyacrylic consistency.

Add reversible stablizer of radical and modified copolymer monomer, guarantee the high fondant-strength after the PP material adds masterbatch, thereby the high speed that guarantees spinning is carried out.

The combination of modified superfine inorganic powder and high fondant-strength PP, ability active adsorption auxiliary agent produces the ultralow effect of separating out.

Add the secondary agglomeration that end group polyolefins hyper-dispersant stops ultrafine inorganic powder, solve the scattering problem of masterbatch, thereby stop fracture of wire in the spinning process, network blocking problem.

Production process: combine Fig. 1; At first be the surface treatment of inorganic powder: 100 parts of inorganic powders comprise lime carbonate, talcum powder, mica powder etc.; Add 0.4-0.9 part non-ionic type surface treatment agent and 0.8-1.2 part propylene quasi-oligomer; Utilize high mixer to carry out the dry method surface treatment, treatment temp to 120 ℃; Add other auxiliary agents then, comprise PE wax, the reversible stablizer of radical, modified monomer, end group polyolefins hyper-dispersant, high fondant-strength PP, the dosage of auxiliary agent is that 0.2-3 part is not waited, and high fondant-strength PP10-30 part is not waited, and takes the dish out of the pot after mixing; Wherein extrusion temperature is set between 180-200 ℃; The granulation mode is looked the masterbatch situation and is decided, comprise air-cooled earnestly, water tie rod, underwater cutpellet and water ring pelletizing.

Beneficial effect: the present invention can be added on the high-speed spinning silk thread, in the high speed drafting process with the acrylic resin good dispersion, plastify phenomenon invariably; Melt strength in the high speed drafting process is high, does not produce the fracture of wire phenomenon; In the high speed spinning process, in one month (adding proportion 10%), can not produce the slurry problem of dripping.
