Waterproof maintaining penetrating agent for leather and preparation method of penetrating agent

Abstract

The invention discloses a waterproof maintaining penetrating agent for leather and a preparation method of the waterproof maintaining penetrating agent. The penetrating agent comprises the following raw materials in parts by weight: 18-25 parts of polyglycerol fatty acid ester, 15-20 parts of dioctyl terephthalate, 2-4 parts of zinc cyanuric acid, 5-6 parts of sodium carbonate, 3-4 parts of sodium tripolyphosphate, 6-8 parts of maleic anhydride, 15-20 parts of chlorcosane, 10-12 parts of dimethicone, 4-5 parts of hexamethylenetetramine, 20-25 parts of glycerol, 6-8 parts of polyurethane fibers, 8-15 parts of barium stearate, 6-8 parts of modified moss and 50-70 parts of water. The penetrating agent consists of esters, polyol and the water and is added with waterproof agent raw materials such as the chlorcosane, dimethicone, so that the penetrating agent has the relatively low surface tension and the relatively good waterproof effect. Compared with the prior art, the penetrating agent has the advantages that the waterproof effect is durable, and the leather is protected when being penetrated; furthermore, by virtue of the modified moss, the comprehensive performance of the penetrating agent can be effectively improved, the even dyeing performance of the penetrating agent is excellent, and the penetrating performance of leather dyes can be obviously improved.

Description

technical field

[0001] The invention relates to textile printing and dyeing technology, in particular to a penetrating agent for waterproofing and maintaining leather and a preparation method thereof. Background technique

[0002] Penetrant, a non-ionic surfactant, can be used as a penetrating aid for textile dyeing baths and finishing baths. The material whose tension is significantly reduced; but because the existing penetrating agent can only withstand the temperature of 150 ℃, the NaOH concentration in the dye solution that can only be tolerated during dyeing and finishing is 80g / L. Alkali-resistant, it is easy to cause the dyeing solution to stratify during the dyeing process, which affects the dyeing effect. Contents of the invention

[0003] The object of the present invention is to provide a penetrating agent for water-repellent maintenance of leather and a preparation method thereof.

[0004] In order to achieve the above object, the present invention adopts...
