Abstract

The utility model discloses a physical blowing synthetic leather, including base cloth layer, foaming layer and surface course to the user state is the benchmark, and surface course and base cloth layer be fixed the laminating in the foaming layer both sides respectively, be equipped with the the thermal expansion foaming body in the foaming layer, the utility model discloses a manufacturing method is simple, forms the expanded foaming layer through the the thermal expansion material in the foaming layer, and synthetic leather finished product elasticity is good, feel, and the product is long -term uses that also not have the carcinogen infiltration human, safe in utilization, accords with european union's standard.

Description

Physical blowing artificial leather

Technical field

This utility model relates to a kind of artificial leather, particularly to a kind of physical blowing artificial leather。

Background technology

Artificial leather application is more and more extensive, in order to make artificial leather have more elasticity, in artificial leather slurry, usually add foaming agent, CBA can discharge the gas such as carbon dioxide and nitrogen in artificial leather slurry after heat resolve, and in polymer forms, form pore, foaming agent makes artificial leather material's a lot of bubbles of internal generation, and then realize artificial leather foaming, artificial leather feel is made to have elasticity, but the recent studies on of European Union finds: when AC foaming agent is heated in the mill, can produce may result in the material semicarbazides of cancer, this material can enter with in the human body of artificial leather Long Term Contact, impact to health。

Utility model content

In order to overcome drawbacks described above, this utility model provides a kind of physical blowing artificial leather, and the manufacturing approach craft of this physical blowing artificial leather is simple, avoiding use AC foaming agent, it adopts the principle of physical expansion to realize artificial leather foaming, has elasticity, and carcinogen will not be produced, use safety。

This utility model be the technical scheme is that a kind of physical blowing artificial leather to solve its technical problem, including base cloth layer, foaming layer and surface layer, to use state for benchmark, surface layer and base cloth layer are fixing respectively fits in foaming layer both sides, is provided with expanded by heating foaming body in described foaming layer。

As further improvement of the utility model, the expanded by heating foaming body in described foaming layer is one or more the combination in some hollow foamed spheroids, expanded by heating resin and sodium bicarbonate (NaHCO3) powder body。

As further improvement of the utility model, each hollow foamed spheroid of described foaming layer, sodium bicarbonate powder body and expanded by heating resin outer are coated with one layer of PVC shell。

The beneficial effects of the utility model are: this utility model manufacture method is simple, facilitate implementation, formed the foaming layer expanded by expanded by heating material in artificial leather foaming layer, artificial leather finished product good springiness, good hand touch, and product life-time service there will not be carcinogen and penetrates into human body, use safety, meet EU criteria。
