Electrostatic flocked product with stable impedance values

Abstract

The invention provides an electrostatic flocked product with stable impedance values. The electrostatic flocked product with the stable impedance values comprises a flocked layer, a bonding layer, a conductive layer and an insulating layer, wherein the flocked layer, the bonding layer, the conductive layer and the insulating layer are sequentially laminated and are tightly connected with one another. The conductive layer is arranged on the insulating layer, so that not only are the overall strength and the overall flexibility of the electrostatic flocked product ensured, but also the impedance on the surface of the insulating layer can be reduced to be close to a conductive state; conductive fiber and the conductive layer are connected firmly through the bonding layer; during impedance detection, current penetrates through the bonding layer and is transmitted along the conductive layer, impedances of all detection points are uniform and deviation values are as low as 103; the impedance values are reduced, and the content of a conductive agent in the bonding layer can also be reduced, so that the content of a bonding agent in the bonding layer can be increased to improve the bonding performance of the bonding layer, the flocked layer can be firmly connected with the other layers, and the overall strength of the electrostatic flocked product is improved.

Description

technical field [0001] The invention relates to a flocking product, in particular to an electrostatic flocking product with stable impedance value. Background technique [0002] With the development of science and technology, various electronic products such as printers, copiers, and fax machines are used in the office field. Such electronic products and equipment are usually equipped with dust removal and anti-static components. Such components in the prior art are usually made in the following two ways: one is to use ordinary plastic parts to flock conductive fibers, and the other is to use conductive cloth base material to weave conductive fibers. But these two craft methods all have certain drawbacks to some extent: [0003] The process of flocking conductive fibers for ordinary plastic parts has the following disadvantages: the overall impedance is relatively high, because the base material of the product is made of ordinary plastic sprayed with conductive glue to ach...

Problems solved by technology

[0003] The process of flocking conductive fibers for ordinary plastic parts has the following disadvantages: the overall impedance is relatively high, because the base material of the product is made of ordinary plastic sprayed with conductive glue to achieve the purpose of overall conductivity of the product, so the overall impedance value of the product will be high; The impedance uniformity of each place is poor. Since the conductive glue itself has a certain impedance value, the distance between the products varies with the length of the distance, and there is a certain deviation in the impedance value between each point. The deviation value is 10. 4 Above, the uniformity is poor; the production efficiency is low, because the conductive glue must be sprayed on the surface of ordinary plastic to conduct electricity, so that the production process of the whole product increases the production process and greatly reduces the production efficiency; production The quality is poor, because the process control in the process of spraying conductive glue is relatively complicated, resulting in poor product quality; the disadvantages of the conductive fabric substrate weaving conductive fiber process are: the product density is low, because the product adopts the weaving method, there is a certain weaving gap between latitude and longitude , so it will lead to the disadvantage of low product density; the height of the product is limited, because the weaving process adopts the method of cutting after weaving, and due to the thickness of the cutter itself, the height of the product is affected to a certain extent, and it cannot be cut. Very low product; the uniformity of impedance between products is poor, and the conductivity of the base fabric is also achieved by adding conductive glue. Since the conductive glue itself has a certain impedance, the distance between the products varies with the length of the distance. There is a certain deviation in the impedance value between points, and the deviation value is 10 4 Above, poor uniformity
