Problems solved by technology

[0003] At present, when the essence is directly applied to the leather surface for fragrance finishing, the volatility of each component molecule of the essence is often high, resulting in that the fragrance retention time of the liquid essence on the leather fiber cannot last long, and it often cannot meet the requirements of high water resistance and high performance at the same time. Requirements for oil resistance

Abstract

The invention discloses a multi-effect leather finishing agent which is mainly prepared from the following components in parts by weight: 1 part of essence, 2-6 parts of nitrocellulose, 10-20 parts of polyvinyl alcohol, 1-5 parts of sodium carboxymethyl cellulose, 2-8 parts of magnesium chloride, 2-4 parts of lauryl sodium sulfate, 3-5 parts of ammonium citrate, 0.5-0.9 part of sodium fluorborate, 12-24 parts of methyl methacrylate, 2-8 parts of hydroxy silicon oil, 1-5 parts of epoxyethane, 3-7 parts of diisocyanate, 1-5 parts of dye, 50-70 parts of ethanol and 500-700 parts of water. Compared with the prior art, the leather treated by the leather finishing agent has higher waterproof grade and oilproof grade, and has the advantages of long aroma duration time and excellent properties.

Description

technical field [0001] The invention relates to a leather finishing agent, in particular to a multi-effect leather finishing agent which is waterproof, oil-proof and prolongs the fragrance duration. Background technique [0002] With the progress of material civilization and the improvement of living standards, consumers are more and more interested in leather products with long-lasting fragrance and special functions. The use of essence to finish the leather, in addition to its fragrance, can also be used as a preservative, bactericide, deodorant, etc., which can not only greatly increase the added value of leather products, but also improve the style of leather products. The field of application can also be expanded. At the same time, in order to meet the needs of the public, there are certain requirements for leather waterproof and oil-proof. Especially with the high development of modern society, the quality requirements of products are getting higher and higher. There...
