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
The present invention relates to the composition of a kind of composition of waterproofing agent, particularly a kind of waterproofing agent for leather.
Background technology
Leather needs to carry out WATER REPELLENT TREATMENT in process, WATER REPELLENT TREATMENT can not affect gas permeability again, and can effectively stop moisture to enter in leather, but after existing waterproofing agent uses, the glossiness of leather can be affected.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, and a kind of reasonable in design, waterproofing agent for leather composition of not affecting leather gloss is provided.
Technical problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of composition of waterproofing agent for leather, is characterized in: it is to be made by the raw material of following weight proportion,
Sodium sulphate 10～20; Hydrochloric acid 10～15;
NaOH 5～10; Ethanol 70～80;
Stearic acid 50～60; Chromium trichloride 40～50;
Sodium carbonate 2～8; Water 15～30.
Technical problem to be solved by this invention can also further realize by following technical scheme.The composition of above-described waterproofing agent for leather is characterized in: the weight proportion of each raw material is,
Sodium sulphate 15; Hydrochloric acid 12;
NaOH 7; Ethanol 75;
Stearic acid 55; Chromium trichloride 45;
Sodium carbonate 6; Water 23.
During making, stearic acid, chromium trichloride and ethanol are fallen in enamel reaction still, be warming up to 70 ℃ through agitating heating, then surplus stock is added reaction, be incubated after 1～2 hour, cooling, standing filtration, filtrate are the present invention.Compared with prior art, the present invention is reasonable in design, makes leather have water resistance, and does not affect leather gloss, can also improve leather quality simultaneously.
