Preparation method of impact-resistant artificial leather

Abstract

The invention discloses a preparation method of an impact-resistant artificial leather, comprising the following steps of: stirring 100 parts of polrvinyl chloride resin, 30-100 parts of plasticizer, 10-80 parts of filler, 0.5-1 part of lubricant, 2-5 parts of heat-resistant stabilizer, 3-5 parts of pigment, 1-10 parts of regulating agent and 3-15 parts of processing agent for 100-200 seconds at the temperature of 120-130DEG C through a high-speed dispersing mixer; charging the mixture obtained in the former step into an internal mixer to mix for 200-300 seconds at the temperature of 130-150DEG C; and charging the product obtained in the former step into a rubber fining mixer for plastication for 10-20 minutes at the temperature of 120-130 DEG C; calendaring into a sheet material with 0.3-0.5mm by a calendar at the temperature of 150-170 DEG C, and fitting the sheet material and a calendaring base material, wherein a fitting pressure is larger than or equal to 1T; and charging into a foaming machine and heating to 190-205 DEG C, foaming, embossing and shaping in a cooling way. The surface of the impact-resistant artificial leather prepared by the method is good in an impact-resistant effect, so that the application range of the impact-resistant artificial leather prepared by the preparation method in the shoemaking and the ball products can be effectively expanded.

Description

technical field [0001] The invention relates to a method for making artificial leather, in particular to a method for making impact-resistant artificial leather. Background technique [0002] The traditional artificial leather feels soft. In some cases, it is required that the artificial leather has a super hard feel. This requires additional support materials to be added to the artificial leather to harden the artificial leather so that it has a super hard feel. This method makes the artificial leather use The material increases, the processing cost is high, and the manufacturing process is complicated. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for manufacturing impact-resistant artificial leather, which has a simple process, and the manufactured artificial leather has strong impact resistance and long service life. [0004] The technical scheme that the present invention adopts in order t...
