Embodiment Construction

[0022] A kind of PP spunbonded non-woven degradable composite material of the present invention, it is made of heavy calcium carbonate, cornstarch, surface treatment agent, POE, polypropylene and polyisobutylene, heavy calcium carbonate, cornstarch, surface treatment The weight ratio of agent, POE, polypropylene and polyisobutylene is (70-85):(15-25):(1-2):(3-7):(55-65):(1-3). In this embodiment, the weight ratio of heavy calcium carbonate, corn starch, surface treatment agent, POE, polypropylene and polyisobutylene is preferably 80:20:1.5:5:60:2.

[0023] PP spunbonded non-woven degradable composite material, its preparation process is as follows:

[0024] 1. First add heavy calcium carbonate and cornstarch to a horizontal double-screw ribbon mixer, heat and mix at a medium speed for 30 minutes to achieve the effect of mixing and drying, and the water content is <2%;

[0025] 2. Add surface treatment agent, mix at high speed for 15 minutes, the treatment agent completely cov...

Abstract

The invention discloses a PP (Polypropylene) spun-bonded non-woven fabric degradable composite material and a preparation process thereof. The composite material is characterized by being mainly prepared from heavy calcium carbonate, corn starch, a surface treating agent, a POE (Polyolefin Elastomer), polypropylene and polyisobutene, wherein the weight ratio of the heavy calcium carbonate to the corn starch to the surface treating agent to the POE to the polypropylene to the polyisobutene is (70-85):(15-25):(1-2):(3-7):(55-65):(1-3). The composite material is produced completely normally on aspun-bonded non-woven fabric machine with an original polypropylene production process, and has the advantages of high filtering performance, high spinnability, pulp dripping resistance, high coloring strength, uniform lapping, normal gram weight, high tensile strength, high flexibility and high surface gloss.

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...
