Abstract
The invention discloses an antistatic fabric with an electrostatic elimination function and a preparation method thereof, wherein a conductive networked nano coating is coated on the fabric by a coating method to prepare the antistatic fabric, and a tiny precise flexible electrostatic excitation electronic component is arranged on the surface of the fabric.
Description
Technical Field
The invention belongs to the technical field of polymer composite materials, and particularly relates to an antistatic fabric with an electrostatic elimination function and a preparation method thereof.
Background
An atom is one of the constituent units of a substance, consisting of a positively charged nucleus and a negatively charged electron outside the nucleus. Substances are composed of molecules, which are composed of atoms, which in turn are composed of positively charged nuclei and negatively charged electrons outside the nuclei. The outer layer electrons of different substance atoms have different capacities required for separating from the substance surfaces, when the surfaces of two objects are contacted and rubbed with each other, electron transfer occurs on the contact surface, the substance with small work function is easy to lose electrons and is positively charged, and the surface of the substance with large work function is increased and obtained electrons are increased so as to be negatively charged. Therefore, the difference in electron work function among different substances is a fundamental cause of generation of static electricity.
The prior antistatic method mainly has two aspects, namely, reducing friction or friction degree and preventing static electricity; on the other hand, the conductivity is improved, and generated charges are conducted away. The friction that is impossible to avoid in use is inevitable to avoid the generation of friction in use, and thus the improvement of the conductivity is the most widely used means at present.
The method for improving the conductivity mainly comprises the modes of fabric after finishing, embedding or blending of conductive fibers, chemical modification of the fibers, nanotechnology and the like. The fabric after-finishing technology adopts the antistatic agent to treat the fabric, improves the hydrophilic property and the electron transfer capability of the fabric through the hydrophilicity of the antistatic agent, is not easy to accumulate charges compared with the fabric before finishing, and improves the antistatic property of the fabric. However, this method cannot completely eliminate static electricity. The conductive fiber embedding or blending technology is a method for improving the antistatic effect of fabric by embedding or blending common fiber fabric, and the electric conduction mainly comprises metal fiber, metal coating fiber, graphite fiber, composite fiber containing conductive carbon black polymer and the like. Static electricity on the fabric can be eliminated through the corona discharge and leakage effects of the conductive fibers, no spark is generated, and more importantly, the method is not influenced by the temperature and the humidity of the environment. However, the scheme has high requirements on the textile technology, and meanwhile, the cost of the fabric can be greatly improved, so that the method is not beneficial to large-scale popularization and application. The antistatic fiber technology has the advantage that the fibers absorb moisture in the surrounding air to increase the conductivity of the fibers, so that the fibers have antistatic capacity. However, this technical principle results in a limited range of applications, and its antistatic effect is very little in a low humidity environment.
The above antistatic methods have advantages in the aspects of static electricity eliminating effect, manufacturing process and cost, and are short in board, so that the problems of static electricity eliminating and cost reduction cannot be perfectly solved. The method needs to eliminate the generated static electricity by means of external conditions, and can not eliminate the charges by self, thereby achieving the antistatic effect.
Disclosure of Invention
In view of the above, the present invention aims to provide an antistatic fabric with an antistatic function and a preparation method thereof, wherein the antistatic fabric is prepared by coating a conductive network nano-coating on the fabric through a coating method, and a micro precise flexible electrostatic excitation electronic component is mounted on the surface of the fabric.

the preparation method of the high-conductivity nano solution comprises the following steps:
(1) after the low conductive material is pretreated, uniformly mixing the pretreated low conductive material with a high-conductivity metal compound solution, and plating a metal layer on the surface of the low conductive material by using a chemical plating method to form a plated metal high conductive material;
(2) coating the prepared high-conductivity material with a nano polymer to prepare a high-conductivity nano material;
(3) adding the cross-linking agent into the organic solvent according to the proportion, stirring to uniformly mix the cross-linking agent and the organic solvent, then adding the high-conductivity nano material into the organic solvent according to the proportion, and fully stirring to uniformly disperse the high-conductivity nano material to obtain the high-conductivity nano solution.
Correspondingly, the invention also provides a preparation method of the antistatic fabric with the static electricity eliminating function, which comprises the following steps:

(2) selectively depositing low-conductivity materials on the fabric by a low-conductivity nano solution through a coating method according to a designed pattern to form a coating surface A, and selectively depositing high-conductivity materials on the fabric by a high-conductivity nano solution through the coating method according to a required pattern to form a coating surface B; and the coating surface A and the coating surface B are connected end to construct a communicated conductive network, and an electrostatic elimination circuit is formed on the surface of the fabric, so that the antistatic fabric is obtained.

More preferably, the antistatic fabric with the function of eliminating static electricity mounts tiny precise flexible static electricity excitation electronic components on the high-conductivity coating, and the tiny precise static electricity elimination devices are composed of diodes, capacitors and switch electronic components (the existing design can be adopted, and the detailed description is omitted).
The invention has the beneficial effects that: according to the conductive networked nano coating with the static electricity eliminating function, the generated static electricity is gathered at the high-conductivity coating surface by the principle that charges are transferred from the low-conductivity coating surface to the high-conductivity coating surface, and then the static electricity is collected and eliminated through a tiny precise flexible static electricity excitation electronic component. The invention realizes the processes of generating, transferring, collecting, exciting and releasing static electricity, exerts the advantages of functional materials, endows the fabric with stable antistatic performance and is not influenced by the ambient environment humidity and temperature. Therefore, on the premise of controlling the cost, the invention can solve the electrostatic pain point in the daily life of the consumer, improve the comfort and the functionality of the clothing product, form the differentiated competition of the product and certainly create great economic value and social benefit for the society and enterprises.
