Preparations of conductive sponge and conductive latex solution

Abstract

The invention relates to a preparation method for conductive sponge and conductive emulsion solution. The preparation method for the conductive sponge comprises steps: firstly, polyurethane sponge is dipped in the conductive emulsion solution for 17-23 minutes; secondly, shaking drying treatment is carried out; thirdly, drying treatment is carried out; fourthly, the dried polyurethane sponge is placed for 48 hours in the room temperature ventilation environment. The preparation method of the conductive emulsion solution is that firstly, urethane resin emulsion solution with 25% contents is preformed; secondly, conductive carbon black is ground into carbon paste; finally, the carbon paste is added into the urethane resin emulsion solution with 25% contents, added with water borne wetting-dispersing agent and stirred in high speed. The conductive sponge prepared by the technical proposal of the invention has fine and uniform cells, and good compressive strength. The sponge materials cannot be corroded in the dipping and drying process. The better rebound resilience of the sponge is reserved. The conductive sponge does not fall crumbs, does not bring about pollution to devices, doesnot volatilize solvents to pollute environment, has the advantages of environmental protection, innocuity, odorlessness and no three wastes generation.

Description

technical field [0001] The technical solution of the invention relates to a preparation method of a sponge and a latex solution, in particular to a preparation method of an aqueous solution soaked conductive sponge and a conductive latex solution. Background technique [0002] In the prior art, there is an antistatic pearl foam made by adding an antistatic agent to the pearl foam. However, this antistatic pearl foam has large cells, low compressive strength, and poor resilience. The resistance and volume resistance are unstable, and the resistance is large, which is 10 8 -10 11 Ω, cannot be adjusted according to customer requirements, the anti-static time limit is short, only 3-6 months, and the anti-static performance is greatly affected by the dry humidity of the environment. [0003] Then there is an antistatic sponge made by adding an antistatic agent to the sponge or soaking the sponge with an antistatic agent. However, although this antistatic sponge has the characte...
