Problems solved by technology

The use of artificial leather and synthetic leather to decorate bags, clothing, shoes, vehicles and furniture has been increasingly recognized by the market. Its wide application range, large quantity and variety are beyond the satisfaction of traditional natural leather.
However, the existing artificial leather often has the disadvantages of fast wear and poor folding resistance.

Embodiment 1

[0024] The raw materials of the high-strength slurry and their weight ratios are: 100 parts of PVC resin powder, 14 parts of nano-titanium dioxide and nano-silica composite material (1:1, average particle size 20nm; specific surface area ≥ 50m / g), 30 parts of epoxy soybean oil, 7 parts of color cake, 2 parts of potassium zinc stabilizer, 2 parts of foaming agent, 30 parts of heavy calcium.

[0025] According to the ingredients, the above-mentioned materials that have been measured are input into the high-speed mixer through the pulse feeder, and the temperature is controlled at 100-150 °C. After the base material (various fabrics) is opened, apply PU slurry (150°C), combine the fully mixed material with the base material with PU slurry, enter the second rolling mill (160°C) for kneading, and then After entering the four-roll calender (temperature 160-190°C), after being flattened, it is cooled to room temperature and curled, and then enters the foam printing machine (180-210°C...

Embodiment 2

[0029] The raw materials of the high-strength slurry and their weight ratios are: 100 parts of PVC resin powder, 13 parts of nano-titanium dioxide and nano-silica composite material (1:1.2, average particle size 20nm; specific surface area ≥ 50m / g), 31 parts of epoxy soybean oil, 7 parts of color cake, 2 parts of potassium zinc stabilizer, 2 parts of foaming agent, 35 parts of heavy calcium. The preparation method is the same as in Example 1.

[0030] The physical and chemical properties of this artificial leather are as follows: peeling load 17N; warp tensile load 228N; weft tensile load 159 N; warp tear load 20N; weft tear load 16N; (23°C, 100,000 cycles -10°C, 35,000 cycles) No cracks on the surface.

Abstract

The invention discloses a nanometer artificial leather. The artificial leather is produced through adding a high-strength slurry by adopting a calendering technology, and the high-strength slurry is produced through blending, by weight, 100 parts of PVC resin powder, 5-15 parts of a composite nanomaterial, 10-40 parts of epoxidized soybean oil, 2-20 parts of color master batches, 3-7 parts of a stabilizer and a foaming agent and 20-40 parts of heavy calcium carbonate. The artificial leather has the advantages of good mechanical performances, good air permeability and good antibacterial characteristic.

Description

technical field [0001] The invention belongs to the field of artificial leather manufacture, and in particular relates to a nanometer artificial leather and a preparation method of the artificial leather. Background technique [0002] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. However, with the growth of the world population, the human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet this demand. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the deficiency of natural leather. The current practice has proved that the excellent performance of synthetic leather cannot be replaced by natural leather. From the analysis of domestic and foreign markets, synthetic leather has also replaced natural leather with insufficient resources in...
