Abstract
The utility model provides a kind of environmental-friendly waterborne polyurethane leather for sport shoes. The leather is characterized by being sequentially composed of a waterborne polyurethane impregnated non-woven fabric, a foaming layer, an adhesive layer, a high-physical-property and high-solid-content resin layer and a surface layer from bottom to top. The product of the environmental-friendly waterborne polyurethane leather for sport shoes disclosed by the utility model has the structure characteristics of environmental friendliness, bending resistance, yellowing resistance and high stripping.
Description
Technical field
The utility model belongs to leather-like, is specifically related to a kind of environment-friendly water-based polyurethane sports shoe leather.
Background technology
Synthetic Leather is a kind of goods of copying natural leather.Usually to weave cotton cloth as base material, polyurethane foaming layer is located on base material, is provided with polyurethane skin layer in foaming layer, through the embossing of embossing wheel, then through top finishing, namely get product.Along with the development of synthetic leather technology, rely on it to have characteristics such as various performance materials near natural leather, the most fields in life is used for replacing natural leather.But it is plane that traditional synthetic leather is usually, pattern simply and only plays decoration function, more demands of era development can't have been satisfied, synthetic leather will be sought survival in variation, seek development in variation, must embody its institutional framework diversity, functional, practicality, fashion, the feature of environmental protection, make it to become main product.
Summary of the invention
The utility model provides a kind of environment-friendly water-based polyurethane sports shoe leather for the problems referred to above.
A kind of environment-friendly water-based polyurethane sports shoe leather is characterized in that, is comprised of successively from bottom to up aqueous polyurethane impregnation nonwoven fabric, foaming layer, adhesive layer, high physical property high solid content resin layer and surface layer.
Described foaming layer is the waterborne polyurethane foaming layer.
Described adhesive layer is the water-base resin of the KT702 model of Ketian Chemical Co., Ltd., Hefei City production.
Described high physical property high solid content resin layer is the high physical property high solid content resin of the KT631 model of Ketian Chemical Co., Ltd., Hefei City production.
Described surface layer is the aqueous polyurethane surface layer.
Product of the present utility model adopts aqueous polyurethane impregnation nonwoven fabric as base material, through operations such as coating, applyings to reach the environment-friendly water-based polyurethane sports shoe leather of footwear materials desired physical properties.For ease of understanding the utility model product, below introduce its preparation method (production of the utility model product is not limited to following methods) by the step simple example:
1, coat the calcium nitrate treatment fluid in this impregnation nonwoven surface, nonwoven fabric can better be contacted with foaming layer, improve peel strength;
2, the nonwoven cloth cover after processing is coated the aqueous polyurethane batch through foaming machine foaming, then dries step by step through 40 meters baking ovens (80～140 ℃) that to make high-intensity waterborne polyurethane foaming layer stand-by;
3, coat anti-flexion, low temperature resistant aqueous polyurethane as surface layer in the release liners that is fit to, coat again the high physical property high solid content resin layer of 0.1mm after 15 meters baking ovens (100～110 ℃) oven dry, be the oven for drying of 10m/min through 20 meters (140～160 ℃) speed, be coated with platform the 3rd and coat the thick water-base resin of 0.18mm to form adhesive layer, to half-dried, half-dried degree differentiation just can take up glue take the finger presses adhesive layer and fit opportunity as the best through 5 meters baking ovens (120 ℃) baking;
4, when the best leather hard of adhesive layer, foaming layer and adhesive layer are dried through the rubber wheel laggard 30 meters baking ovens of applying (110～140 ℃) with appropriate gap, pressure, speed is controlled at 10～12m/min, form synthetic leather after the adhesive layer oven dry, by rolling table, synthetic leather is separated with release liners again, make environment-friendly water-based polyurethane sports shoe leather of the present utility model, product has the design feature that environmental protection, anti-flexion, anti-xanthochromia, height are peeled off.
