Abstract

The invention provides a composition of waterproof agents for leather. The composition of the waterproof agents for the leather is made of the following raw materials according to the following weight percentage: 10-20 of sodium sulfate, 10-15 of hydrochloric acid, 5-10 of sodium hydroxide, 70-80 of ethanol, 50-60 of stearic acid, 40-50 of chromium trichloride, 2-8 of sodium carbonate and 15-30 of water. In a preparation process, the stearic acid, the chromium trichloride and the ethanol are added into a ceramic reaction kettle to obtain a mixture I, the mixture I is stirred and heated until the temperature of the mixture I rises to 70 DEG C, then the rest raw materials are added into the ceramic reaction kettle for reactions to obtain a mixture II, after the temperature of the mixture II is maintained for 1-2 hours, the mixture II is subjected to cooling, still standing and filtering to obtain a filtrate, and the filtrate is the composition of the waterproof agents for the leather. The composition of the waterproof agents for the leather is reasonable in design, enables the leather to have a waterproof function, cannot affect luster of the leather and can improve the quality of the leather at the same time.

Description

technical field [0001] The invention relates to a composition of waterproofing agent, in particular to a composition of leather waterproofing agent. Background technique [0002] The leather needs to be waterproofed during processing, and the waterproofing can not affect the air permeability, and can effectively prevent moisture from entering the leather, but the luster of the leather will be affected after the existing waterproofing agent is used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leather waterproofing agent composition with reasonable design and without affecting the gloss of leather in view of the deficiencies of the prior art. [0004] The technical problem to be solved by the present invention is achieved through the following technical solutions. The invention is a composition of leather waterproofing agent, which is characterized in that: it is made of the following raw materials in weight...
