Problems solved by technology

[0003] Coating conventional fiber fabrics with PVC artificial leather is economical and practical. However, PVC artificial leather has defects such as poor aging resistance, heavy odor (high T-VOC, high atomization value), and poor environmental protection. The situation of ordinary PVC artificial leather in China is more severe

Embodiment 1

[0022] Step 1: In parts by mass, mix 100 parts of 2600 type polyvinyl chloride resin powder, 80 parts of TOTM plasticizer, 2 parts of calcium zinc heat stabilizer and 1 part of U485 type light stabilizer, and stir for 7 minutes;

[0023] Step 2: Put the mixture stirred in Step 1 into the internal mixer, plasticize at 100°C for 3 minutes, then add to the open mixer to continue plasticizing for 20 minutes, and set the temperature of the open mixer to 145°C;

[0024] Step 3: Press the plasticized mixture into a film through a four-roller calender; the temperature of the four rolls is set at 185°C, 180°C, 170°C, and 160°C respectively, and compounded with the base cloth, and then cooled by the cooling wheel Winding to obtain semi-finished products;

[0025] Step 4: Send the semi-finished product into the foaming oven for low-temperature foaming; the foaming oven is a 6-stage foaming oven, and the oven temperature is set as: 160 degrees for the first stage, 170 degrees for the seco...

Embodiment 2

[0028] Step 1: In terms of parts by mass, mix 100 parts of 2600 type polyvinyl chloride resin powder, 80 parts of TOTM plasticizer, 3 parts of calcium zinc heat stabilizer and 1 part of U485 type light stabilizer, and stir for 7 minutes;

[0029] Step 2: Put the mixture stirred in step 1 into the internal mixer, plasticize at 100°C for 3 minutes, then add to the open mixer and continue to plasticize for 20 minutes, and set the temperature of the open mixer to 155°C;

[0030] Step 3: Press the plasticized mixture into a film through a four-roller calender; the temperature of the four rolls is set at 185°C, 180°C, 170°C, and 160°C respectively, and compounded with the base cloth, and then cooled by the cooling wheel Winding to obtain semi-finished products;

[0031] Step 4: Send the semi-finished product into the foaming oven for low-temperature foaming; the foaming oven is a 6-stage foaming oven, and the oven temperature is set as: 160 degrees for the first stage, 170 degrees f...

Embodiment 3

[0034] Step 1: In parts by mass, mix 100 parts of 2600 type polyvinyl chloride resin powder, 80 parts of TOTM plasticizer, 2 parts of calcium zinc heat stabilizer and 1 part of U485 type light stabilizer, and stir for 6 minutes;

[0035] Step 2: Put the mixture stirred in Step 1 into the internal mixer, plasticize at 100°C for 3 minutes, then add to the open mixer and continue to plasticize for 20 minutes, and set the temperature of the open mixer to 150°C;

[0036] Step 3: Press the plasticized mixture into a film through a four-roller calender; the temperature of the four rolls is set at 185°C, 180°C, 170°C, and 160°C respectively, and compounded with the base cloth, and then cooled by the cooling wheel Winding to obtain semi-finished products;

[0037] Step 4: Send the semi-finished product into the foaming oven for low-temperature foaming; the foaming oven is a 6-stage foaming oven, and the oven temperature is set as: 160 degrees for the first stage, 170 degrees for the se...

Abstract

The invention discloses an anti-aging-aging anti-wrinkle low-atomization-value water-based automobile leather and a preparation method thereof, and belongs to the field of artificial leather and manufacture. The automobile leather comprises the following components: polyvinyl chloride resin powder, a TOTM plasticizer, a calcium-zinc heat stabilizer and a U485 type light stabilizer; the automobileleather prepared from the environment-friendly plasticizer, odorless stabilizer and other environment-friendly components by the method is environmentally-friendly, durable, odorless, anti-aging and anti-wrinkle. The thermal aging reaches 4.5, T-VOC value is below 30 mu gc / g, and atomization property is 2 mg or less. The smell of non-metallic materials in a car reaches level 10 which reaches the odorless standard.

Description

technical field [0001] The invention belongs to the field of artificial leather and its manufacture, in particular to a preparation method of anti-aging and anti-wrinkle water-based automobile leather with low atomization value. Background technique [0002] Synthetic leather currently used in automotive interiors mainly includes polyvinyl chloride (PVC) leather and PU leather. Car door panels, seat cushions, instrument panels, interior walls of compartments and other parts are mainly made of PVC leather for compounding. [0003] Coating conventional fiber fabrics with PVC artificial leather is economical and practical. However, PVC artificial leather has defects such as poor aging resistance, heavy odor (high T-VOC, high atomization value), and poor environmental protection. The situation of ordinary PVC artificial leather in China is more severe. [0004] Therefore, preparing a light-smell, environment-friendly artificial leather with anti-aging performance has always be...
