Problems solved by technology

These high energy consumption and high emission products are bound to seriously pollute the local environment, posing a major threat to people's production, life, and public life and health.
On the other hand, in the production process of domestic synthetic leather, the use of masterbatches and solvent-based pigment pastes to color leather products affects the environmental protection indicators of the products and seriously restricts the import and export trade of my country's leather products.

Embodiment Construction

[0034] The formula of the embodiment of the invention is referring to Table 1:

[0035] Table 1: (unit: weight percentage)

[0036]

[0037] According to above-mentioned prescription, preparation method carries out as follows:

[0038] ①. Reserve 10% deionized water, add 90% deionized water and dispersing wetting agent into the mixer and disperse at a speed of 500-700r / min for 15 minutes to obtain the first mixed solution;

[0039] ②. Add the functional additive to the first mixed solution obtained in step ① and mix evenly to obtain the second mixed solution;

[0040] ③. All the ecological pigments are dropped into the second mixed solution obtained in step ② to obtain an ecological liquid pigment predispersion for synthetic leather;

[0041]④. Disperse the eco-type liquid pigment predispersion for synthetic leather obtained in step ③ at a speed of 1500-3000r / min for no less than 30 minutes, and slowly add the pH value regulator and the reserve in step ① during the disper...

Abstract

The invention discloses an ecotypic liquid pigment for synthetic leather, comprising the following raw materials in the total weight percentage: 21.0-75.0 percent of pigment, 1.0-25.0 percent of functional assistant, 0.2-0.5 percent of pH value regulator, 2.0-20.0 percent of dispersion wetting agent and the balance of deionized water. Quality detection, vacuum defoaming and filter packaging are carried out after all components are mixed and ground to finally obtain the required ecotypic liquid pigment for the synthetic leather. The ecotypic liquid pigment for the synthetic leather has the advantages of high stability, reasonable preparation process, low cost, simple production flow and easy industrial production, does not contain alkylphenol ethoxylates (APEO), polycyclic aromatic hydrocarbon (PHAs), heavy metal, formaldehyde, carcinogenic aromatic amide (AZO), ethylene glycol or a micromolecule surface active agent and is universal for a DMF (Dimethyl Formamide) system and an aqueous system.

Description

technical field [0001] The invention relates to an ecological liquid pigment for synthetic leather coloring, in particular to an ecological liquid pigment for synthetic leather and a preparation method thereof. Background technique [0002] The National Development and Reform Commission listed "water-based and ecological synthetic leather research and development, production and artificial leather, synthetic leather finishing material technology" as an encouraged development project in the industrial structure adjustment guidance catalog. Coloring materials are indispensable in the production process of synthetic leather and artificial leather. At present, DMF (N, N-dimethylformamide), solvent-based pigment paste or color masterbatch are used in the leather-making process. [0003] This coloring material is made using solvents such as toluene, xylene, acetone, methyl ethyl ketone, ethyl acetate, and dimethylformamide. These organic solvents are harmful substances; color mast...
