Static-free glue and preparation method thereof

Abstract

The invention belongs to the technical field of chemical engineering, specifically components of static-free glue. The static-free glue comprises the following components in part by weight: 4.7-8 parts of cellulose, 2.3-4 parts of cooked glue powder, 41-64 parts of tung oil and 24-53.1 parts of conductive filler; the preparation method comprises the following steps of: adding the cellulose in the formula ratio to the water for sufficiently mixing uniformly to acquire cellulose solution, wherein the mass ratio of the cellulose to the water is (1.5-2.3) to 100; specifically, the preparation method is as follows: adding the coked glue powder to the cellulose solution, adding the tung oil in the formula ratio for sufficiently mixing after uniformly mixing to acquire the glue, wherein the acquired glue is added with conductive filler in the formula ratio, and then uniformly dispersed to acquire the static-free glue. The static-free glue has the characteristics of a simple preparation process, no poisonous and harmful substances, low cost, strong practicability and the like, and can be widely applied to performing electrostatic defending to a precise instrument, a life use, a building and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to an antistatic glue and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the wide use of various electrical equipment, the electromagnetic environment is becoming more and more complex in our daily life and industrial production. Many materials will generate static electricity during use. Excessive static electricity accumulation may cause extreme Terrible consequences, such as the human body may be injured by static electricity, the static electricity in the experimental environment that requires high cleanliness may generate dust and affect the experimental results, the electronic components of precision instruments may be damaged by static electricity breakdown, explosives, oil During the production, storage and transportation of high-risk items such as static electricity, sparks may cause combu...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the antistatic adhesives reported at home and abroad use metal particles as fillers, such as nano-silver powder, flake gold powder, copper powder, etc. These materials are not only expensive, but also have migration phenomenon of metal particles, which will reduce their static electricity after long-term use. protective effect

Chinese patent CN1244558A discloses a kind of TiC engineering ceramic powder as conductive base material, SiO 2 It is an inorganic conductive adhesive that uses water glass or modified water glass as a curing agent as a filler, but its curing conditions are complicated, the cost is high, and it is brittle when used, so it is only suitable for bonding instruments and equipment, etc.
