Embodiment Construction

[0022] A kind of PP spunbond non-woven fully degradable composite material of the present invention, it is mainly made of cornstarch, polyvinyl alcohol, glycerin and organic montmorillonite, the weight ratio of cornstarch, polyvinyl alcohol, glycerin and organic montmorillonite (55-65): (15-25): (13-18): (3-8); wherein, the weight ratio of corn starch, polyvinyl alcohol, glycerin and organic montmorillonite is preferably 60:20:15: 5. The particle size of heavy calcium carbonate is 2500 mesh, and the particle size of corn starch is 2000 mesh.

[0023] PP spunbonded non-woven fully degradable composite material, its process steps are as follows:

[0024] 1. First, mix the cornstarch in a horizontal high-speed mixer for 30 minutes at medium speed to achieve the effect of mixing and drying, and the water content is <2%;

[0025] 2. Add polyvinyl alcohol, mix at high speed for 10 minutes, and distribute and mix the components evenly;

[0026] 3. The mixed material is transported...

Abstract

The invention discloses a polypropylene (PP) spun-bonded nonwoven fabric fully-degradable composite material and a preparation method thereof. The PP spun-bonded nonwoven fabric fully-degradable composite material is characterized by being mainly prepared from corn starch, polyvinyl alcohol, glycerol and organic montmorillonite according to a weight ratio of (55-65):(15-25):(13-18):(3-8). The PP spun-bonded nonwoven fabric fully-degradable composite material has the advantages of good filtration performance, good spinnability, no slurry dropping, good colorability, uniform lapping, normal gram weight, good tensile strength and flexibility, good surface luster and good 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] The quality and performance of meltblown nonwovens depends on the correct selection of polypropylene raw material (melt index) and the optimization of processing conditions. At present, meltblown manufacturers mainly use high-melting polypropylene raw materials, but they lack the necessary flexibility to adapt to different market demands, and there is also the pressure of high costs. In this case, high-quality melt-blown non-woven fabrics can be produced by using low-melt index spun-bonded polypropylene raw materials (MFI=20-50), combined with plastic additives using "chain breaking technology", for Meltblown manufacturers provide more flexible operating space. At present, PP spunbonded non-woven fabrics are made of PP polypropylene raw mate...
