Preparation method of skin-imitated woven summer sleeping mat synthetic leather

Abstract

The invention discloses a preparation method of skin-imitated woven summer sleeping mat synthetic leather. The preparation method comprises the following steps: S1, soaking a synthetic leather base fabric into an immersion trough, beating while immersing, taking out the synthetic leather base fabric, squeezing out the water and ironing for later use; S2, dissolving polyurethane resin and polyether resin into a DMF (Dimethyl Formamide) solution, and then adding zinc stearate, calcium stearate, an antistatic agent, carbodiimide and 4,4'-diamido-3,3'-dichlorodiphenylmethane for mixing, then redispersing carbon fibers, aggregate, wood powder and a thickening agent, adding the DMF solution, and adjusting the viscosity of slurry, thus obtaining the slurry; and S3, coating the surface of the base fabric with the slurry until the slurry is completely solidified, taking out, washing with methyl tertiary butyl ether, ethanol and water, then drying, shaping, cooling and carrying out flower roll embossing, thus obtaining the skin-imitated woven summer sleeping mat synthetic leather. The preparation method provided by the invention has the advantages of simple operation, abundant resources of raw materials and low production cost; and in addition, the prepared product has the advantages of smooth surface, high hydrolysis resistance, high wear resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a preparation method of artificial leather woven mat synthetic leather. Background technique [0002] Natural leather is widely used in the production of daily necessities and industrial products due to its excellent natural characteristics. However, with the growth of the world population, the human demand for leather has doubled, and the limited amount of natural leather has long been unable to meet this demand. In order to solve this contradiction, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the deficiency of natural leather. Synthetic leather is widely used in bags, shoes, household items and other fields due to its low price and uniform quality.

Problems solved by technology

[0003] Summer mat is one of the commonly used furniture items in people's daily life. It mainly includes straw weaving and bamboo weaving. It needs to be weaved in the preparation process. The method is cumbersome, and the source of raw materials is scarce, which makes the production price of summer mat generally high.

In recent years, some imitation leather woven mats have appeared on the market, but the hydrolysis resistance is generally low, and it is easy to absorb water and cause mildew during use, which affects its aesthetics and service life.
