Embodiment 1

[0019] The raw materials of the high-strength slurry and their weight ratios are: 100 parts of PVC resin powder, nano-titanium dioxide and nano-silica composite material (1:1, average particle size 20nm; specific surface area ≥ 50m 2 / g) 14 parts, 30 parts of epoxidized soybean oil, 7 parts of color cake, 2 parts of potassium zinc stabilizer, 2 parts of foaming agent, 30 parts of heavy calcium.

[0020] 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 with PU slurry, enter the second rolling mill (160°C) for kneading, and then After entering the four-roll calender (temperature 160-190 ℃) and calen...

Embodiment 2

[0024] The raw materials of the high-strength slurry and their weight ratios are: 100 parts of PVC resin powder, nano-titanium dioxide and nano-silica composite material (1:1.2, average particle size 20nm; specific surface area ≥ 50m 2 / g) 13 parts, 31 parts of epoxidized 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.

[0025] This artificial leather physical and chemical property is as follows: stripping load 17N; Warp tensile load 228N; Weft tensile load 159N; Warp tear load 20N; Weft tear load 16N; 23°C, 100,000 cycles -10°C, 35,000 cycles) No cracks on the surface.

Abstract

Disclosed is a nanometer artificial leather. The artificial leather is manufactured by means of a calendering method by adding a high-strength slurry. The high-strength slurry is made of components of the following weights: 100 portions of PVC resin power, 5 to 15 portions of a nanometer composite material, 10 to 40 portions of epoxidized soybean oil, 2 to 20 portions of a color masterbatch, 3 to 7 portions of a stabilizer and a blowing agent, and 20 to 40 portions of heavy calcium carbonate. The artificial leather of the present invention has desirable mechanical performance, and has desirable ventilation and anti-bacterium properties.

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...
