Embodiment 1

[0030] Formula: 100 parts of polyvinyl chloride resin, 45 parts of dioctyl phthalate, 2 parts of barium zinc stabilizer, 5 parts of foaming agent, 6 parts of titanate coupling agent.

[0031] Processing technology:

[0032] Mixing: Feed according to the requirements of the formula sheet, and use a 55KW mixer to mix at high speed for 4-5 minutes to make the mixture evenly stirred.

[0033] Banburying: put the mixed material into a 10,000-horsepower machine for banburying, and pay attention to the change of current during the banburying process. When the current reaches about 100A, add foaming agent and banbury for 30 seconds.

[0034] Milling: The temperature of the mill must be controlled at about 170°C to ensure that the material is fully plasticized.

[0035] Extrusion: The temperature of the extruder is controlled at about 135°C, pay attention to feeding evenly and avoid stacking.

[0036] Four-roll calendering: To control the temperature of the four rolls, the first roll...

[0039] Formula: 100 parts of polyvinyl chloride resin, 40 parts of dioctyl phthalate, 3 parts of barium zinc stabilizer, 4 parts of foaming agent, and 8 parts of titanate coupling agent.

[0040] Processing technology is with embodiment 1.

Embodiment 3

[0042] Formula: 100 parts of polyvinyl chloride resin, 50 parts of dioctyl phthalate, 2 parts of barium zinc stabilizer, 6 parts of foaming agent, and 5 parts of titanate coupling agent.

[0043] Processing technology is with embodiment 1.

Abstract

The invention discloses flocking substrate artificial leather which contains the following components by weight: 100 portions of polyvinyl chloride resin resin, 40-50 portions of dioctyl phthalate, 2-portions of barium-zinc stabilizers, 4-6 portions of foaming agents and 5-8 portions of titanate coupling agents. The invention further discloses a processing method of the flocking substrate artificial leather. Compared with the similar products on markets, suede leather made of the flocking substrate artificial leather has good hand feeling and touching, excellent resilience, strong fluffy feeling, high tear strength, good cohesion, difficult falling off and foaming of fluff, good aging resisting performance, high hydrolysis resistance, high acid-alkali resistance, high scraping resistance and easy cleaning; the cost of flocking is lower, the processing technology is simple and easily operated; the flocking substrate artificial leather is the optimum substitute of flocking cloth, and is an ideal choice for making mahjong tabletop cloth or other similar products of sports and entertainment currently.

Description

technical field [0001] The invention relates to a flocking substrate artificial leather and a processing method thereof. Background technique [0002] With the continuous application of various new materials and technologies, PVC artificial leather is also constantly updated. After years of development, PVC artificial leather has been widely used in bags, shoes, clothing, furniture, car interiors, sports and entertainment products and other fields, and has entered people's daily life, showing strong vitality in the market. At present, a large part of mahjong tablecloths used for mass entertainment is flocked by flocking factories on the cloth surface to make it have a fluffy feel, thereby making a suede surface. However, this kind of cloth fleece product has a lot of loss and high cost, especially the fluff on the cloth surface is very easy to fall off, it is very troublesome to flock the second time, and the cost of exchanging old for new is extremely high.
