Problems solved by technology

In the production process of PP spunbonded non-woven fabrics, in order to produce colored fabrics, coloring agents need to be added. Because the dosage is small and it is not easy to disperse evenly, it is usually made into color masterbatches. Commonly used are black masterbatches and red masterbatches. and white masterbatch, etc., but the color masterbatches currently on the market generally have shortcomings such as poor spinnability, dripping, and dull surface, which are difficult to meet the needs of production

Embodiment Construction

[0023] The present invention is a kind of PP spunbond non-woven fabric white masterbatch, it is mainly made of rutile titanium dioxide, heavy calcium carbonate, superdispersion modifier, POE and polypropylene, rutile titanium dioxide, heavy calcium carbonate, superdispersion The weight ratio of modifier, POE and polypropylene is (95-105): (25-35): (1-3): (15-25): (1-3); among them, rutile titanium dioxide, heavy The weight ratio of calcium carbonate, hyperdispersion modifier, POE and polypropylene is preferably 100:30:2:20:2. The particle size of heavy calcium carbonate is 2400-2600 mesh.

[0024] The preparation process of PP spunbond non-woven white masterbatch, its process steps are as follows:

[0025] 1. First heat the rutile titanium dioxide and heavy calcium carbonate in a high-speed mixer, and mix them at a medium speed for 30 minutes to achieve the effect of mixing and drying, and the water content is <2%;

[0026] 2. Add ultra-dispersion modifier, mix at high speed...

Abstract

The invention discloses a PP (Polypropylene) spun-bonded non-woven fabric white master batch, which is characterized by being mainly prepared from rutile type titanium dioxide, heavy calcium carbonate, a hyper-dispersion modifier, a POE (Polyolefin Elastomer) and polypropylene, wherein the weight ratio of the rutile type titanium dioxide to the heavy calcium carbonate to the hyper-dispersion modifier to the POE to the polypropylene is (95-105):(25-35):(1-3):(15-25):(1-3). The master batch has the advantages of high whiteness, high filtering performance, high spinnability, pulp dripping resistance, high surface gloss and good popularization value.

Description

technical field [0001] The invention relates to the technical field of PP spunbonded nonwoven fabric color masterbatch, and more specifically relates to a PP spunbonded nonwoven fabric white masterbatch and a preparation process thereof. Background technique [0002] At present, PP spunbonded non-woven fabrics are made of PP polypropylene raw materials. After high-temperature spinning and carding of equipment and bonding into a web, a breathable rather than water-permeable fiber structure is formed between the fibers by physical methods to achieve physical moisture-proof and mildew-proof. , The ideal effect of anti-moth. It is mainly used in women's sanitary napkins, diapers, napkins, clothing interlinings, shoe and hat interlinings, and disposable surgical gowns, surgical caps, operating table covers, and is widely used in artificial leather, furniture, chemicals, printing, decoration, packaging, automobiles , building materials services, industrial and mining geotextiles,...
