Embodiment

[0026] Embodiment: a kind of method for making synthetic leather of sandwich cloth, concrete steps are as follows:

[0027] Step 1: Wet Mixing Ingredients:

[0028] Coating Mixing Ingredients:

[0029] a. Stir 5-10kg of dimethylformamide and 3-7kg of wet-process hydrolysis-resistant color paste at high speed for 15-20 minutes, then filter and set aside;

[0030] b. Mix and stir 20-55kg dimethylformamide, 0.5-3kg hydrolysis-resistant additive and 0.5-2kg surfactant for 15-20 minutes;

[0031] c. Stir the mixture in step a for another 5-15 minutes, then add 100kg of wet-process high hydrolysis-resistant regenerated polyurethane resin, stir for 2 hours at a temperature of 20°C-40°C, make it fully mixed, then vacuumize and filter under negative pressure Static, defoaming stand-by;

[0032] Dipping Mix Ingredients:

[0033] d. Stir 10-15kg of dimethylformamide and 5-15kg of wet-process hydrolysis-resistant color paste at high speed for 15-20 minutes, then filter and set aside; ...

Abstract

The present invention discloses a method for manufacturing netted sandwich cloth synthetic leather, including: stirring uniformly and filtering dimethylformamide and wet hydrolysis resistance paste; then continuously stirring for 5-15 minutes, adding the wet high hydrolysis resistance recycled polyurethane resin, mixing and defoaming; stirring dimethylformamide, a hydrolysis resistance additive and a surfactant uniformly; stirring and filtering the dimethylformamide and the wet hydrolysis resistance paste for standing by; stirring the wet high hydrolysis resistance recycled polyurethane resin and dimethylformamide uniformly, adding the surfactant and the former mixture to stir uniformly, scraping the mixture on the netted sandwich cloth by a method integrating dipping, coating and scraping in one, solidifying to form film, washing and drying to fix the shape to get wet base, stirring high hydrolysis resistance dry polyurethane resin, dimethylformamide, toluene, butanone, dry hydrolysis resistance paste and the surfactant, scraping and coating the mixture on release paper, and then adhering the wet base. The product produced by the present invention is high in density, low in elongation, difficult to produce fracture lines, good in flexibility, and high in fullness sense.

Description

technical field [0001] The invention relates to a manufacturing method of artificial leather, in particular to a manufacturing method of sandwich cloth synthetic leather. Background technique [0002] At present, the base cloth of high-density leather used in sports shoes with special functions is only formed by mixing non-woven fabric and wet-process resin. Fracture marks are prone to occur during the process. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for making synthetic leather with mesh cloth. The method for making synthetic leather with mesh cloth is simple in process, and the elongation of the product produced is small. The sports shoes made of it are not easily deformed and difficult to Fracture marks appear, good elasticity, strong sense of fullness. [0004] The technical scheme that the present invention adopts in order to solve its technical problem is: a kind of sandwich fabric...
