Description

Antistatic dust-free paper Technical Field The utility model relates to the technical field of dust-free paper, in particular to antistatic dust-free paper. Background The dust-free paper needs to have antistatic performance mainly because static electricity can cause a series of problems in the production, storage and use processes of the dust-free paper, the static electricity can adsorb dust and tiny particles, the cleanliness of the dust-free paper is reduced, and the damage to sensitive electronic elements can be caused, so that the dust-free paper has the antistatic performance by adding an antistatic agent or adopting special process treatment, the generation and accumulation of the static electricity can be effectively reduced, and the product quality and the production safety are protected. Based on the above-mentioned circumstances, in prior art, the patent of application number CN202122862023.1 discloses a compound antistatic dust-free paper, including packing carton and dust-free paper body, dust-free paper body includes the wood fiber layer, and be provided with the layer that absorbs water on the wood fiber layer both sides outer wall, all be provided with antibacterial layer on the both sides outer wall of layer that absorbs water, and bond on the both sides outer wall of antibacterial layer has the sponge layer, compound shaping has dust-free paper layer on the both sides outer wall of sponge layer, and all the spraying has antistatic spectrum rete on the both sides outer wall of dust-free paper layer, this dust-free paper passes through the antistatic spectrum rete that sets up, antistatic spectrum rete can play antistatic effect to this dust-free paper, and then can make the surface of this dust-free paper more soft when using, and can improve the quality of this dust-free paper.
