Abstract

The invention relates to water-based matte oil-resistant synthetic leather and a preparation method thereof. The synthetic leather comprises a base cloth layer, a solvent-free bonding layer and a dry-method PU surface layer which are sequentially arranged, and the synthetic leather further comprises an oil-resistant surface treatment layer formed on the dry-method PU surface layer; the raw material formula of the oil-resistant surface treatment layer is prepared form the components in parts by weight: 20-30 parts of a bright-surface polycarbonate anti-doodling auxiliary agent; 70-80 parts of a matte polycarbonate anti-doodling auxiliary agent; 8-10 parts of a cross-linking agent; 20-25 parts of a catalyst; and 0-10 parts of a solvent. According to the water-based matte oil-resistant synthetic leather and the preparation method thereof, the water-based dry-method PU surface layer is subjected to surface treatment by adopting a specific surface treating agent, so that the synthetic leather not only has a matte effect, but also has oil-resistant and anti-doodling performance, particularly has excellent stain removal performance on stains of a ball-point pen and a marking pen, and is easy to clean.

Description

technical field

[0001] The invention belongs to the technical field of synthetic leather, and in particular relates to a water-based fog surface oil-resistant synthetic leather and a preparation method thereof. Background technique

[0002] With the development of my country's economy and the continuous improvement of people's living standards, the value of environmental protection has become increasingly prominent, and it has become the first element in measuring development. The weight of environmental protection will directly determine the living space and sustainable development ability of synthetic leather enterprises, and ecological synthetic leather and clean production have become the development trend of the industry.

[0003] Now more and more companies are committed to the development of water-based synthetic leather products. However, the water-based synthetic leather products currently on the market are usually high-gloss products, and some high-end products, su...

Examples

Embodiment 1

[0032] The water-based matte oil-stain-resistant synthetic leather provided by the present embodiment includes a base cloth layer, a solvent-free adhesive layer, a dry-process PU surface layer and an oil-stain-resistant surface treatment layer arranged in sequence, wherein,

[0033] In this example, the base fabric layer uses 0.85 double black gray imitation cotton wool.

[0034] In this example, the raw material composition of the solvent-free adhesive layer is: 100 parts of BASF's 2500C-A polyol, 30 parts of calcium carbonate, 0.2 parts of BASF's 95C-CC curing agent and 85 parts of BASF's 2500C-B isocyanate prepolymer.

[0035] In this example, the raw material composition of the dry PU surface layer is: 100 parts of water-based polyurethane fabric from Zhejiang Huafeng Synthetic Resin Co., Ltd., 0.15 parts of thickener, 1.5 parts of wetting and leveling agent and 13 parts of color paste.

[0036] In this example, the raw material formula of the anti-oil stain surface treat...
