Problems solved by technology

If an antistatic agent is used to coat the surface of the material, its aging and antistatic effects will be worse, and it does not meet environmental protection requirements
If the conductive polymer material is coated on ordinary insulating plastic sheets, plastic films, cloth, paper, etc., the effect is better, but there are the following problems: large waste and high cost
[0008] There are two main types of commonly used anti-static fabrics: 1) Weaving conductive silk into the fabric, the disadvantage is that the surface resistance is high, generally 10 8-11 Ω, its anti-static effect is not particularly good, and the conductive thread is easy to break after repeated washing
[0009] 2) The disadvantage of dipping the cloth in antistatic liquid is that the surface resistance is relatively high, generally 10 9-11 Ω, its anti-static effect is not good, so it cannot be used many times
[0010] At present, there is no antistatic paper and nylon mesh on the market.

Abstract

The invention discloses an antistatic hot melt glue and coated method, which comprises the following steps: a, allocating the antistatic hot melt glue with 5-8 wt hot melt glue and 2-5 wt conductive powder through volume portion; filling the melt glue into glue jar; heating at 150-190 deg.c; making in a molten condition; b, driving electrical insulating material move to one direction with driving drum of hot melt glue coating machine; pumping the molten hot melt glue into coated head through gear pump; coating on the surface of insulating base material. The insulating base material possesses a finite conductivity property, which can drop the surface resistance.

Description

technical field [0001] The present invention relates to hot-melt adhesive modification technology, in particular to an anti-static hot-melt adhesive and a process for coating the anti-static hot-melt adhesive on an insulating base material, so that the original insulating plastic sheet, plastic film, cloth, The surface of paper, nylon mesh, etc. has a certain conductivity to reduce its surface resistance and play an antistatic role. Background technique [0002] With the improvement of people's awareness of environmental protection and anti-static products, market competition forces the reduction of costs, as well as the serialization and diversification of demand. [0003] For ordinary insulating plastic sheets, plastic films, cloth, paper, nylon nets, etc., due to their large surface resistance (generally greater than 10 12 Ω), cannot meet the anti-static requirements, so it is necessary to make some functional improvements to ordinary insulating plastic sheets, plastic s...
