The artificial leather imitating TPU according to claim 1, characterized in that, the molecular weight of the high molecular weight diol CM-44 is 1000-3000; the molecular weight of the single-terminal dimethylsiloxane diol is 2000-4000; the foaming temperature of the AC foaming agent is 15...

Embodiment 2

[0030] The TPU-like PVC artificial leather is prepared from PVC slurry by calendering, and the raw materials and weight ratios of the PVC slurry are:

[0031]

[0032]

[0033] According to the ingredients, the above-mentioned materials measured are input into the high-speed mixer through the pulse feeder, and the temperature is controlled at 100-150 ° C. After fully stirring, they enter the internal mixer, and the temperature is controlled at (160 ° C) for several minutes; After the base material (various fabrics) is opened, apply PU slurry (150°C), combine the fully mixed material with the base material on which PU slurry is applied, enter the second rolling mill (160°C) for kneading, and then After entering the four-roll calender (temperature 160-190°C) and calendering, it is cooled to room temperature and curled, and then enters the foam printing machine (160-180°C) to be foamed and pressed into various patterns, and then it is inspected by rolls and packed into the w...

Abstract

The present invention relates to a TPU imitating PVC artificial leather, which is prepared from a PVC slurry by using a calendering method, wherein the PVC slurry comprises, by weight, 100 parts of PVC resin powder, 6.5-20 parts of high molecular weight diol CM-44, 1.5-4.5 parts of mono-terminated dimethylsiloxane diol, 0.15-0.4 part of a small molecular weight diol chain extender, 1.3-4 parts of diisocyanate, 0.15-0.4 part of fumed silica, 0.13-0.4 part of LDPE, 0.02-0.07 part of acrylic acid grafted maleic anhydride, 0.01-0.04 part of erucylamide, 2-4 parts of an AC foaming agent, 0.04-0.15 part of sodium hydrogen carbonate, 0.05-0.15 part of calcium stearate, 0.05-0.15 part of hydrogenated silicone oil, 5-15 parts of a nanometer composite material, 10-40 parts of epoxy soybean oil, 2-20 parts of color cake, 3-7 parts of a stabilizer, and 20-40 parts of heavy calcium carbonate. According to the present invention, the TPU imitating PVC artificial leather uses the nanometer composite material as the wear-resistant agent, such that the defect that the single nanometer material difficultly achieves the high wear resistance is overcome, and the nanometer composite material, PTY and other components synergistically act so as to substantially improve the wear resistance of the PVC artificial leather.

Description

technical field [0001] The invention belongs to the field of artificial leather manufacture, and in particular relates to a TPU imitation artificial leather. Background technique [0002] With the continuous improvement of people's living standards and the increasing development of the plastics industry, PVC artificial flooring has gradually replaced solid wood flooring and entered thousands of households. At present, in the production process of domestic PVC artificial leather flooring, PVC resin powder, plasticizers, heavy Calcium, stabilizer, foaming agent, and other main raw materials. PVC plastic plastic floor coils are used in factories, hospitals, offices, etc. It is made of PVC plus plasticizer and other additives and calendered on cloth. But this common artificial leather floor has poor stain resistance, poor wear resistance, is afraid of cigarette butt burns, and has poor impact resistance. Contents of the invention [0003] The object of the present invention...
