Determine 1-3 parts and colorant 4-6 parts of agent.
The beneficial effects of the present invention are:
The present invention by the way that conductive auxiliary agent is being added in PU surface material, in PVC surface material be added conductive auxiliary agent and
Metal powder (aluminum paste) reaches the technology effect for improving the electric conductivity of artificial leather cladding so that surface layer be made to obtain electric conductivity
Fruit, and the concrete component of surface layer is designed, so that the electric conductivity obtained can form the medium of conduction weak current with human body, in turn
So that artificial leather is obtained touch screen functionality, and it is of the invention can touch screen artificial leather there is the good flexible performance and standard used touch screen
True performance.Artificial leather of the invention can be made into gloves or protection tool, can also use in the same old way.
Specific embodiment
To explain the technical content, the achieved purpose and the effect of the present invention in detail, it is explained below in conjunction with embodiment.
The most critical design of the present invention is: conductive auxiliary agent is added in surface material, acquisition makes surface layer obtain electric conductivity
Can, and the concrete component of surface layer is designed, so that the electric conductivity obtained can form the medium of conduction weak current with human body, in turn
Artificial leather is set to obtain touch screen functionality.
The present invention provide one kind can touch screen artificial leather, including the surface layer and foaming layer set gradually, the surface layer is the face PU
Layer or PVC surface layer, the PU surface layer include that following parts by weight prepare raw material: 95-105 parts of polyurethane resin, solvent 100-110
Part, 0.1-0.3 parts of levelling agent, 2-4 parts of conductive auxiliary agent, 13-16 parts of aging agent and 1-10 parts of colorant；The PVC surface layer includes
