Abstract

The invention provides an aqueous treating agent applied to surface treatment of PVC (Polyvinyl Chloride) artificial leather, and a preparation method of the aqueous treating agent. The aqueous treating agent comprises aqueous waterborne polyurethane resin, styrene-acrylate resin, aqueous acrylic resin, paraffin emulsion, silicon dioxide powder, aqueous polyether modified polysiloxane, 2,2,4-trimethyl-1,3-pentanediol mano-isobutyric acid ester, ethylene glycol monobutyl ether and an aqueous colorant; the raw materials are added into a stirring kettle to be uniformly mixed and stirred so as to obtain a mixture paste; and furthermore water is added to adjust the viscosity of the mixture paste so as to obtain the aqueous treating agent. The aqueous treating agent can be formed into a coating with good adhesion on the surface of the PVC artificial leather, and along with the change of the proportions of various components, the glossiness and the hand-feeling of the surface of the PVC artificial leather can be adjusted within a large range. The aqueous treating agent can take the place of a solvent type surface treating agent, thereby eliminating solvent pollution caused by the fact that the solvent type surface treating agent is used in the PVC artificial leather production.

Description

technical field [0001] The invention belongs to the technical field of PVC artificial leather, in particular to an aqueous treatment agent for surface treatment of PVC artificial leather and a preparation method thereof. Background technique [0002] The initial development of artificial leather and synthetic leather is to imitate the structure of leather and develop substitute materials for leather to solve the problems of insufficient raw materials and environmental pollution in leather production. Among them, artificial leather is the earliest leather substitute material developed, and it still occupies half of the artificial leather and synthetic leather industry so far. According to the statistics of the National Bureau of Statistics, the national output of artificial leather and synthetic leather was 2.14 million tons in 2010, and reached 2.41 million tons in 2011, ranking first in the world in terms of total production. Among them, the output of PVC artificial leathe...
