Problems solved by technology

[0003] At the same time, in the process of preparing synthetic leather, the leather surface needs to be polished. However, the existing synthetic leather polishing agents have poor temperature resistance and scratch resistance. Natural and bright, therefore, the existing surface polishing agents can no longer meet the increasing requirements of consumers for the surface brightness, color and feel of synthetic leather. Polishing agent for synthetic leather feel, color and brightness

[0021] The mercerizing treatment agent for synthetic leather is composed of the following raw material components, which include 33 parts of resin, 6 parts of ethyl acetate, 36 parts of toluene, 15 parts of cyclohexanone, 0.6 parts of silica matting powder, 0.7 parts of E wax, elastic powder 7 parts, 0.2 parts of slip agent.

[0022] The production technology of synthetic leather of the present invention is as follows for mercerizing treatment agent:

[0023] Step 1: According to the formula, mix 23 parts of resin, 6 parts of ethyl acetate, 15 parts of cyclohexanone, 36 parts of toluene, 0.6 parts of silica matting powder, 0.7 parts of E wax and 0.2 parts of slip agent, grind and filter to obtain mixture 1;

[0024] Step 2: Add 10 parts of the remaining resin and 7 parts of elastic powder to the mixture 1 obtained in step 1, stir evenly, and use the resin to adjust the haze of the product to obtain a qualified mercerizing treatment agent for synthetic leather.

Embodiment 2

[0026] The mercerizing treatment agent for synthetic leather is composed of the following raw material components, which include 30 parts of resin, 5 parts of ethyl acetate, 35 parts of toluene, 13 parts of cyclohexanone, 0.4 parts of silica matting powder, 0.6 parts of E wax, elastic powder 5 parts, slip agent 0.1 part.

[0027] The production technology of synthetic leather of the present invention is as follows for mercerizing treatment agent:

[0028] Step 1: Mix 20 parts of resin, 5 parts of ethyl acetate, 13 parts of cyclohexanone, 35 parts of toluene, 0.4 part of silica matting powder, 0.6 part of E wax and 0.1 part of slip agent according to the formula, grind and filter to obtain mixture 1;

[0029] Step 2: Add 10 parts of the remaining resin and 5 parts of elastic powder to the mixture 1 obtained in step 1, stir evenly, and use the resin to adjust the haze of the product to obtain a qualified mercerizing treatment agent for synthetic leather.

Embodiment 3

[0031] The mercerizing agent for synthetic leather is composed of the following raw material components: based on the total weight of the resin, it contains 35 parts of resin, 7 parts of ethyl acetate, 37 parts of toluene, 17 parts of cyclohexanone, and 0.8 parts of silica matting powder , 1 part of E wax, 10 parts of elastic powder, and 0.3 part of slip agent.

[0032] The production technology of synthetic leather of the present invention is as follows for mercerizing treatment agent:

[0033] Step 1: Stir 25 parts of resin, 7 parts of ethyl acetate, 17 parts of cyclohexanone, 37 parts of toluene, 0.8 parts of silica matting powder, 1 part of E wax and 0.3 parts of slip agent according to the formula, grind and filter to obtain mixture 1;

[0034] Step 2: Add 10 parts of the remaining resin and 10 parts of elastic powder to the mixture 1 obtained in step 1, stir evenly, and use the resin to adjust the haze of the product to obtain a qualified mercerizing treatment agent for...

Abstract

The invention relates to a mercerizing agent for synthetic leather. The mercerizing agent comprises the following components in parts by mass: 30-35 parts of resin, 5-7 parts of acetic ester, 35-37 parts of toluene, 13-17 parts of cyclohexanone, 0.4-0.8 parts of silica matting powder, 0.6-1 part of E wax, 5-10 parts of elastic powder, and 0.1-0.3 parts of a smoothing agent. The invention also discloses a preparation method of the mercerizing agent for synthetic leather. Partial resin, acetic ester, cyclohexanone, toluene, silica matting powder, E wax, and the smoothing agent are stirred according to the formula, grinding and filtering are carried out in order to obtain a mixture 1, residual resin and the elastic powder are added into the mixture 1 with uniform stirring, resin is used for adjusting haze of a product, after the product is qualified, the mercerizing agent for synthetic leather is obtained; after treatment, the leather surface has good layering, unique hand feeling and good haze; leather prepared by using the mercerizing agent has natural luster, clear color, good mercerizing effects, good scraping resistance, and good integrative effects.

Description

technical field [0001] The invention relates to a mercerizing treatment agent for synthetic leather, in particular to a mercerizing treatment agent for synthetic leather applied to the front-end process of synthetic leather and a preparation method, which belongs to an innovative front-end material. Background technique [0002] The synthetic leather surface treatment agent can be used for surface finishing according to the product category, so as to improve the brightness, color and feel of the synthetic leather, and make the synthetic leather closer to genuine leather. However, as consumers have higher requirements for leather surface color and feel, not only the smooth feel of synthetic leather must be increased, but also natural luster, clear color, strong layering, good haze, and strong scratch resistance. Mercerizing effect is good and so on. [0003] At the same time, in the process of preparing synthetic leather, the leather surface needs to be polished, and the exi...
