Abstract

The invention relates to medium-coarse Yangba pressure-change resin for synthetic leather. The medium-coarse Yangba pressure-change resin is prepared from the following raw materials in parts by weight: 50-52 parts of high-film Yangba resin, 20-22 parts of butanone, 16-18 parts of methylbenzene, 4-6 parts of a pressure toner, 2-4 parts of medium-coarse Yangba powder and 0-1 part of a wear-resistant additive. The invention further discloses a preparation method of the medium-coarse Yangba pressure-change resin for the synthetic leather. The method comprises the steps of mixing one part of high-film Yangba resin, the methylbenzene, the pressure toner and the medium-coarse Yangba powder according to the formula and filtering; adding the butanone and the wear-resistant additive and stirring evenly; and adding the remaining high-film Yangba resin, stirring evenly to obtain the medium-coarse Yangba pressure-change resin for the synthetic leather. Various components of the medium-coarse Yangba pressure-change resin coordinate with one another and work together, so that after Yangba is foamed, the medium-coarse Yangba pressure-change resin is uniform in cells, good in velvet hand feeling and obvious in color difference after hot stamping.

Description

technical field [0001] The invention relates to a medium-thick yambuck pressure-set resin for synthetic leather, in particular to a medium-thick yambuck pressure-set resin for synthetic leather used in the front-end process of synthetic leather, which belongs to an innovative front-end material. The invention also relates to a preparation method of medium-thick yangbuck pressure-set resin for synthetic leather. Background technique [0002] The synthetic leather surface treatment agent can be used for surface finishing according to the product category, which can improve the brightness, color and feel of the synthetic leather, making the synthetic leather closer to genuine leather. However, as consumers have higher and higher requirements for the color and feel of the leather surface, not only the brightness and feel of the synthetic leather must be increased, but also the synthetic leather is required to have a clear color and high elasticity. And existing surface treatmen...
