The artificial leather mainly comprises PVC artificial leather and PU synthetic leather, and is a plastic product with similar appearance and hand feeling to leather. However, the existing color cakes have poor compatibility with raw materials of the artificial leather, so that the coloring effect of the color cakes is reduced.
Disclosure of Invention
In order to improve compatibility of the color cake and the artificial leather, the color cake has a good coloring effect when being used for the artificial leather, and the application provides the color cake for coloring the artificial leather and the preparation method of the color cake.
In a first aspect, the present application provides a color cake for artificial leather coloring, comprising the following raw materials in weight percent:
PVC：13-22％
and (3) a plasticizer: 18-33%
Calcium carbonate: 10-30%
Toner: 30-40%
Processing aid: 2-5%
Diffusion agent: 0.5-1.5%.
The color cake obtained by the scheme has good dispersibility and compatibility with resin, and can improve the coloring effect when being used for coloring artificial leather; wherein, calcium carbonate is as white filler, plays the effect of filling reinforcement, and low price, and the source is extensive, can improve processability for the look cake that obtains has better structural stability, and then is difficult for appearing cracked phenomenon, is used for the synthetic leather can improve the color stability of synthetic leather, makes the synthetic leather color uniformity.
Because the artificial leather is PVC artificial leather or PU artificial leather, the compatibility of the color cake and an artificial leather raw material system can be improved by adopting PVC as a resin carrier, so that the color cake is easy to disperse in the artificial leather raw material system, and the coloring effect of the artificial leather can be improved.
The plasticizer has plasticizing effect, so that the PVC has better toughness and plasticity. The plasticizer can reduce the processing temperature of PVC in the resin, increase the lubricity of a PVC macromolecular chain, increase the toughness and the impact resistance, reduce the tensile strength and the like, and the polymerization degree of the PVC can be selected to be 800-1250; the color cakes prepared by the PVC are easy to have similar compatible action with the artificial leather, so that the dispersibility of the pigment in a raw material system of the artificial leather (the artificial leather is PU artificial leather or PVC artificial leather) is increased, the color cakes are uniformly colored, the color powder can be selected from phthalocyanine red, phthalocyanine blue, phthalocyanine green, titanium pigment, carbon black and the like, and the pigment has a good coloring effect on the artificial leather.

The color cakes obtained in examples 1 to 11 and comparative examples 1 to 2 were subjected to observation of whether or not breakage, bending, collapse and the like occurred, and recorded as shown in Table 1.
1. Performance testing
2.1 Reference QB/T1648-1992, wherein the amount of color cake is 5%, test items are: a. color strength (%); b. migration (stage) resistance: more than 4 is qualified; c. heat resistance (grade) greater than 4; d. dispersibility: dispersity, individual/(100 mm. Times.100 mm), of 3 or less; e. color point: disallowing; specific experimental data are shown in table 1.
2) Cutting the color cakes obtained in examples 1-11 and comparative examples 1-2 into small blocks (which are convenient to enter a feed inlet of an injection molding machine), performing injection molding by the injection molding machine to form test bars, wherein the injection molding temperature of the injection molding machine is 130 ℃, and further testing notch impact strength (23 ℃) by referring to GB/T1043.1-2008, and specific experimental data are shown in Table 1;
TABLE 1 Experimental data for examples 1-11 and comparative examples 1-2
As can be seen by combining examples 1-11 and comparative example 1 and combining Table 1, the color strength, migration resistance, heat resistance and the like of examples 1-11 are better than those of comparative example 1, which indicates that the color cakes obtained by the preparation method of the present application have better dispersibility, further the dispersibility of the color cakes in artificial leather can be improved, the coloring effect of the color cakes is improved, and the notch impact strength of examples 1-11 is higher than that of comparative example 1, further the color cakes obtained by the preparation method of examples 1-11 have better toughness, so that the color cakes are not easy to collapse, break and the like in the transportation or storage process.
As can be seen from the combination of examples 1 to 11 and comparative example 2 and Table 1, examples 1 to 11 are better in coloring strength, migration resistance, heat resistance and the like than comparative example 2, which means that the color cake obtained by using PE as a carrier in comparative example 2 is poor in compatibility with the raw material in the artificial leather, and further poor in dispersibility of the color cake in the raw material of the artificial leather, and further reduced in coloring effect of the color cake.
As can be seen from the combination of examples 1-3 and 5 and the combination of Table 1, the coloring strength, migration resistance, heat resistance and the like of example 5 are better than those of examples 1-3, which shows that the addition of modified PVC and modified calcium carbonate is beneficial to improving the compatibility of modified PVC with modified calcium carbonate and toner, stabilizing the color cake structure, and simultaneously, enabling the color cake to be easily dispersed in the raw materials of the artificial leather, and improving the coloring effect of the color cake.
As can be seen from the combination of examples 8 to 9 and example 5 and the combination of Table 1, the coloring strength, migration resistance, heat resistance and the like of example 5 are better than those of examples 8 to 9, which means that the PVC is modified after the CPU and the rosin resin are blended, so that the color cake has better toughness, the color cake is not easy to collapse, break and the like in the transportation, production and storage processes, and the coloring effect, the dispersibility and the compatibility with the artificial leather raw materials of the color cake can be improved to a greater extent.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
