Embodiment 1

[0026] A method for making water-based matte, scratch-resistant, and soft synthetic leather, characterized in that the specific steps are as follows:

[0027] Step 1: The production of Bass: first prepare the wet-process polyurethane coating, then clean the base cloth, iron it once, dry it once, then vacuum defoam the wet-process polyurethane coating, and then apply the wet-process polyurethane coating Put it on the base cloth, then enter the coagulation tank for coagulation, then wash with water, squeeze dry, fix the width, iron it for the second time, dry it for the second time, cool it, and wind it up to make the bass.

[0028] Step 2: Preparation of water-based matte surface treatment agent: 100 parts of water-based PU resin, 50 parts of deionized water, and 1 part of water-based plasticizer are stirred at a speed of 800-1000 rpm for 5-10 minutes to prepare Add 1 part of curing agent to the mixed liquid A and stir evenly at a speed of 800-1000 rpm to obtain a water-based t...

Embodiment 2

[0032] A method for making water-based matte, scratch-resistant, and soft synthetic leather, characterized in that the specific steps are as follows:

Abstract

The invention relates to the technical field of synthetic leather making and in particular relates to a method for making water-based matte scratch-resistant and flexible synthetic leather. The methodcomprises the following steps: a Beth making step, namely preparing a wet polyurethane coating, cleaning the base fabric, performing vacuum defoamation on the wet polyurethane coating, coating the wet polyurethane coating on the base fabric, entering a coagulating basin to be coagulated, washing, wiping, fixed-width expanding, performing secondary ironing and secondary drying, cooling, and rolling to make Beth; and a step of making a water-based matte treatment agent, namely preparing a mixed solution from a water-based PU resin, deionized water and a water-based plasticizer, and adding a curing agent, thereby obtaining the water-based treatment agent. The synthetic leather made by the method disclosed by the invention is soft in hand feeling, high in coating fullness, excellent in flexibility, wear-resistant, scratch-resistant, yellowing-resistant, permanent in elasticity, extremely low in odor, environmental-friendly and capable of realizing pure water environment friendliness, doesnot have free formaldehyde, and does not contain APEO (Alkylphenol Ethoxylates), potassium phthalate, isocyanates and other toxic and harmful component residues.

Description

technical field [0001] The invention relates to the technical field of synthetic leather production, in particular to a production method of water-based matte, scratch-resistant and soft synthetic leather. Background technique [0002] The materials used to make leather in the early days were all taken from animal skins such as cowhide or pigskin. Although these animal leather products have good elasticity and wear resistance, the materials available are limited and the cost performance is high, so they cannot be widely popular among ordinary consumers. have. [0003] In order to meet the needs of consumers, synthetic leather was born as an alternative material. The cost of synthetic leather is low, and the price of making shoe uppers and seat cushions with it is cheap and beautiful. Therefore, bags, sofas, and cushions made of synthetic leather have also gained popularity recognized by consumers. Synthetic leather is a plastic product that simulates the composition and ...
