Problems solved by technology

[0003] Double-sided leather in PU synthetic leather has become a new favorite in the market, but the existing double-sided leather is a laminated product, that is, the back of the original leather (base cloth surface) is coated with a layer of textured dry leather with high viscosity resin. However, this method is more complicated in craftsmanship, and the style is restricted by product production, which cannot meet the diverse needs of consumers.

Abstract

The invention discloses a production method of environment-friendly composite polyurethane synthetic leather. The production method sequentially includes: producing front-side leather, producing rear-side leather, preparing a water-borne compositing agent, and compositing the front-side leather and the rear-side leather to obtain the double-sided leather. A preparation method of the water-borne compositing agent includes the steps of firstly, preparing epoxy resin composite water-borne polyurethane prepolymer; secondly, preparing a silane coupling agent modified epoxy resin composite water-borne polyurethane emulsion; thirdly, preparing a silane coupling agent modified epoxy resin composite water-borne polyurethane adhesive. The production method has the advantages that the adhering effectof the double-sided leather is increased, and the double-sided leather is free of environment pollution, noncombustible, nontoxic, wide in adaptability, environmentally friendly, suitable for being popularized and used and the like.

Description

technical field [0001] The invention relates to synthetic leather, in particular to a production method of environment-friendly composite polyurethane synthetic leather. Background technique [0002] In recent years, the world's synthetic leather industry center has gradually shifted to my country, promoting the rapid development of my country's synthetic leather industry. With the enhancement of consumers' awareness of environmental protection and the increase of consumer demand, the synthetic leather industry is gradually developing towards the trend of ecological environmental protection and functional diversity. Among them, ecological functional synthetic leather has become the development trend of the industry, and with its own advantages, it is ushering in a golden age of rapid development. For the new generation of polyurethane synthetic leather, the selection of more environmentally friendly polyurethane raw materials, the reduction of toxic and harmful substances i...
