Description
Technical field
The present invention relates to the leather processing field, in particular to without aldehyde pulling color agent and preparation method thereof.
Background technology
On fur grass in the market, the pulling color agent of frost making use be take sodium formaldehyde sulfoxylate as main.
Although its, effect was better dawn, can produce the harmful substances such as formaldehyde in its use procedure.Diazolidinyl Urea in the pulling color operating process, endanger the healthy of operator simultaneously, and the residual a large amount of formaldehyde of meeting on the fur after dawn, and the harm user's is healthy.
Summary of the invention
The object of the present invention is to provide without aldehyde pulling color agent and preparation method thereof, to solve the above problems.
Provide in an embodiment of the present invention without the agent of aldehyde pulling color, in parts by weight, by following component, made:
First compound 10-50 part; Bleeding agent 2-10 part; Solid organic acid 10-30 part; The molecular formula of described the first compound is
Without the preparation method of aldehyde pulling color agent, comprise following concrete steps:
The solid organic acid that adds 10-30 part in first compound of 10-50 part, mix; The molecular formula of described the first compound is
Be heated to 20-30 ℃, add the bleeding agent of 2-10 part to stir 10-20 minute.
Reductant the first compound used in the present invention is to be replaced as organic group R at the part inorganic group by strand in existing sodium dithionite
1, R
2, R
3those skilled in the art can directly obtain this method of replacing by the relevant knowledge of having controlled, can stable existence after the first compound after displacement is water-soluble, and not carrying aldehyde radical, the first compound does not have harmful substance formaldehyde generation or residual when as reductant, fur being carried out to pulling color.Because the pH value of solution can not be too high when pulling color, not so can injure fur simultaneously, cause the hair on fur to come off, so, need to add solid organic acid.Be in order to increase the infiltration of reductant on fur and add bleeding agent, increase the dawn degree.
Preparation method's synthesis technique without the agent of aldehyde pulling color provided by the invention is simple simultaneously, environmental protection.
