Problems solved by technology

[0003] The existing PU artificial leather uses toner, but the toner needs to be mixed and stirred before use, and the toner particles are relatively large, so when dyeing artificial leather, the dyeing is uneven and easy to fade. How to develop a PU full-color paste to replace As for panchrome powder, it is necessary to solve the problem of uneven dispersion of color paste. For this reason, the present invention proposes a preparation method of PU panchrome paste equivalent to panchrome powder, which is used to solve the deficiencies in the prior art

Abstract

The invention discloses a preparation method of PU (polyurethane) full color paste capable of being equivalent to full toner. The preparation method comprises following steps: raw materials of color paste are prepared and comprise components in parts by weight as follows: 10-20 parts of an efficient dispersing agent, 3-8 parts of an adhesive, 3-8 parts of a preservative, 3-8 parts of a surface modifier, 3-8 parts of a defoaming agent and 60-80 parts of diacetone alcohol, diacetone alcohol is added to a stirrer, the surface modifier is added, the rotating speed is adjusted to be 600-800 r / min, the rotating speed of the stirrer is adjusted to be 800-1000 r / min, the temperature is adjusted to be 65-95 DEG C, the reaction time is 60-120 min, and a mixed solution B is obtained; the mixed solution B is put in a three-roll grinder and ground 2-5 times until fineness is smaller than 0.01 mm, the defoaming agent is added to a product obtained in S4, the product is put in the stirrer and stirred until bubbles disappear, and the color paste is obtained. The color paste is ingenious in design, good in dyeing effect and adhesion effect and suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of PU color paste, in particular to a preparation method of PU full color paste equivalent to full color powder. Background technique [0002] Polyurethane artificial leather has been widely used in every aspect of people's life. However, the traditional method of directly adding powdered pigments is still used in coloring, which has two disadvantages: firstly, dry powdered pigments are easy to drift and be inhaled by the human respiratory tract during mixing, polluting the environment and affecting health; secondly, most of the ordinary pigments are in 400 mesh , that is, the particle size is about 38 microns, and the amount of pigments with the same effect is about 10 times that of imported pigments with a particle size of 1000 to 1200 microns and a particle size of 10 to 13 microns, and the price of imported pigments is 20 to 25 times that of ordinary pigments. Expensive shades are watered down thanks to...
