Embodiment Construction

[0023] The present invention is a special composite material for PP spunbonded non-woven fabric, which is mainly made of heavy calcium carbonate, superfine talcum powder, surface treatment agent, POE, polypropylene and polyisobutylene, heavy calcium carbonate, superfine talcum powder , surface treatment agent, POE, polypropylene and polyisobutylene weight ratio is (85-95): (5-15): (1-2): (4-8): (54-62): (1-3 ); Among them, the weight ratio of heavy calcium carbonate, superfine talc, surface treatment agent, POE, polypropylene and polyisobutylene is preferably 90:10:1.5:5:60:2. The particle size of heavy calcium carbonate is 2500 mesh, and the particle size of corn starch is 2000 mesh.

[0024] The preparation process of PP spunbonded non-woven special composite materials, its process steps are as follows:

[0025] 1. First add heavy calcium carbonate and ultra-fine talc powder to a horizontal double-ribbon mixer, heat and mix at a medium speed for 30 minutes to achieve the ef...

Abstract

The invention discloses a composite material special for a PP (Polypropylene) spun-bond non-woven fabric and a preparation process thereof. The composite material is characterized by being mainly prepared from powdered whiting, superfine talc powder, surface treating agent, POE (Polyolefin Elastomer), polypropylene and polyisobutene in weight ratio of (85-95):(5-15):(1-2):(4-8):(54-62):(1-3). Thecomposite material has the advantages of favorable filtering performance and spinnability, no color dripping, favorable coloring performance, uniformity in net laying, normal gram weight as well as strong tensile strength, favorable soft performance, surface gloss and popularization value.

Description

technical field [0001] The invention relates to the technical field of PP spun-bonded non-woven fabrics, and more specifically relates to a PP spun-bonded non-woven fabric composite material and a process. 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, and industrial filter cloth oil...
