Problems solved by technology

[0002] The traditional artificial leather is a combination of multiple colors and patterns on the surface of a single-color product through printing and other subsequent processes. When it is used, the overall sense is rigid, dull, and the texture is poor. The pattern has no three-dimensional effect and is not full enough.

Embodiment

[0028] Embodiment: a kind of method for making powder wax synthetic leather, concrete steps are as follows:

[0029] Step 1: Wet Mixing Ingredients:

[0030] a. Stir 5-10kg of dimethylformamide and 0.5-2kg of color paste at high speed for 80-100 minutes, then filter and set aside;

[0031] b. Mix 100-120kg of dimethylformamide and 20-30kg of wood powder and stir for 20-30 minutes, then fully swell for 30-40 minutes, then add the filtered mixture in step a and stir evenly for later use;

[0032] c. Add 100kg polyurethane wet-process resin to the mixture formed in step b, stir for 30-40 minutes, and defoam for 40-50 minutes;

[0033] Step 2: Wet bass production:

[0034] Squeeze the slurry formed by degassing in step 1 on the textile fabric fibers, then immerse it in an aqueous solution of dimethylformamide with a concentration of 18-22% by mass for solidification, and then go through at least one water rolling process, and then A wet bass is obtained after washing and drying...

Abstract

The invention discloses a manufacturing method of powder-wax synthetic leather. The method comprises the steps of mixing 5-10 parts of dimethyl formamide and 0.5-2 parts color paste uniformly; filtering the mixture; adding 100-120 parts of dimethyl formamide and 20-30 parts of wood powder to the above mixture, stirring uniformly and swelling; adding 100 parts of a polyurethane wet resin, stirring uniformly, defoaming and coating the obtained mixture on the textile fabric fiber; immersing in a solution of 18-22% dimethyl formamide to make the mixture solidified, squeezing water, washing with water and drying to obtain a wet base; mixing 100 parts of polyurethane dry resin, 15-20 parts of dimethyl formamide, 15-20 parts of butanone, 15-20 parts of toluene, 0.5-1.0 part of an auxiliary agent and 3-5 parts of a toner uniformly and coating the obtained mixture on release paper to obtain a dry veneer; adhering the wet base to the dry veneer, drying, separating from the release paper, heat-embossing, cool-shaping, coating a surface-treatment agent with relatively strong powder-wax feeling on the embossed surface; drying and cooling. The obtained product has strong powder-wax feeling; full patterns, soft and delicate hand feel.

Description

technical field [0001] The invention relates to a method for making artificial leather, in particular to a method for making powdered wax synthetic leather. Background technique [0002] The traditional artificial leather is a combination of multiple colors and patterns formed on the surface of a single-color product through printing and other subsequent processes. When it is used, the overall sense is rigid, dull, poor texture, and the pattern has no three-dimensional effect and is not full enough. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for producing powdered wax synthetic leather. The production method of powdered waxed synthetic leather has a simple process, and the produced product has a strong powdery waxy feeling, full pattern, soft and delicate hand feeling. [0004] The technical scheme that the present invention adopts in order to solve its technical problem is: a kind of powder ...
