Description
Technical field
The present invention relates to PU mill base technical fields, more particularly to a kind of preparation side of the panchromatic slurries of PU that can be equivalent with panchromatic powder
Method.
Background technology
Polyurethane artificial leather has been widely used the every aspect of people's life.But tradition is still continued to use in terms of coloring
Way is directly added into pigment powder, and its drawback has two：Dry powder state pigment easily drifts about and by human respiratory tract in spice first
Suction, pollute environment and unhealthful；Secondly, common pigments are mostly in 400 mesh, the i.e. microns of particle diameter 38, equivalent effect
Pigment usage amount, be 1000~1200 mesh, 10 times or so of 10~13 microns of import pigment of particle diameter, the price of import pigment is again
20~25 times of common pigments.Due to generation visitor's color matching services of import pigment, expensive shade has been watered down.
Existing PU artificial leathers use toner, but toner is using preceding needing to mix, and the particle of toner compared with
Greatly, it is uneven so as to be dyed when being dyed to artificial leather, easily fade, how to research and develop a kind of panchromatic slurries of PU to replace panchromatic powder
, it is necessary to it is uneven to solve the problems, such as that mill base disperses, therefore, the present invention proposes a kind of system of the panchromatic slurries of PU that can be equivalent with panchromatic powder
Preparation Method, for solving the deficiencies in the prior art.
The content of the invention
The invention aims to solve shortcoming present in prior art, and the one kind proposed can be equivalent with panchromatic powder
The panchromatic slurries of PU preparation method.
To achieve these goals, present invention employs following technical scheme：
A kind of preparation method of the panchromatic slurries of PU that can be equivalent with panchromatic powder, comprises the following steps,
S1, prepare the raw material of mill base, include the raw material of following parts by weight：10~20 parts of dispersant with high efficiency, 3~8 parts of adhesive, prevent
Rotten 3~8 parts of agent, 3~8 parts of surface modifier, 3~8 parts of defoamer, 60~80 parts of diacetone alcohol, 1~5 part of antifreezing agent, pigment 1
