Abstract

The invention relates to a cold-resistant acrylic emulsion leather auxiliary agent and a preparation method thereof, and relates to the technical field of leather auxiliary agents. The leather auxiliary agent is prepared from, by weight, 1,000-2,360 parts of mixed monomers, 0-375 parts of polymerized monomers, 2,400-3,500 parts of water, 20-50 parts of alkali liquor, 20-60 parts of emulsifier, 0-30 parts of preservative, 0.1-10 parts of initiator, 0.1-10 parts of sodium dithionite, 0.1-10 parts of tert-butyl hydroperoxide and 20-40 parts of zinc oxide. The invention further provides the preparation method of the leather auxiliary agent. The leather auxiliary agent prepared by means of the preparation method has good cold and bending resistance, leather treated by the leather auxiliary agent has the advantages that the glossiness, gloss retention performance, plasticity, dry rub resistance, wet rub resistance, flexibility and water resistance of the leather are improved, and the treatedleather can keep excellent hand feeling. In addition, the preparation method is simple, easy to operate, stable in process and suitable for mass industrial production.

Description

Technical field: [0001] The invention relates to the technical field of leather auxiliary agents, in particular to a cold-resistant acrylic emulsion leather auxiliary agent and a preparation method thereof. Background technique: [0002] Leather auxiliaries are mainly used for leather modification, especially in the process of polishing and ironing of various front leathers and buffed leathers. Leather auxiliaries can firmly bond the coating to the leather surface and improve High-temperature ironing resistance of leather, and leather auxiliaries must keep leather products in a stable state and excellent characteristics in various environments. [0003] At present, the main component of leather auxiliaries is mostly acrylic emulsion. After the acrylic emulsion on the market is formed into a film, it can be used normally at room temperature without any problem. That is, when wearing and using, the coating is prone to breakage. After several experiments, the present inventio...
