Conductive paint for doors and preparing method thereof

Abstract

The invention discloses conductive paint for doors. The conductive paint is prepared from, by weight, 45-55 parts of polyaniline, 18-20 parts of polypyrrole, 25-40 parts of carbon fiber, 7-12 parts of petroleum coke, 8-16 parts of silicon carbide, 20-25 parts of graphite, 6-9 parts of silver powder, 7-11 parts of nickel powder, 20-22 parts of single-walled carbon nanotube, 36-40 parts of stannic oxide, 23-25 parts of zinc oxide, 22-24 parts of sodium pyrophosphate, 4-8 parts of tri-ethyl hexyl phosphoric acid, 16-20 parts of sodium hexametaphosphate, 7-9 parts of sodium carboxymethylcellulose, 11-15 parts of oxidized polyethlene wax, 3-5 parts of pvc resin, 12-16 parts of bismaleimide, 20-25 parts of ethyl acrylate, 6-10 parts of cellulose nitrate and 13-16 parts of terpilenol. The conductive paint for doors has an electromagnetic shielding function, influences of external electromagnetic fields are avoided, material dispersion is uniform, bonding effect is good, and the conductive paint is quite suitable for doors.

Description

technical field [0001] The invention relates to a conductive paint for a door and a preparation method thereof. Background technique [0002] Conductive coatings are anti-electromagnetic interference shielding coatings. Commonly known as: conductive paint. Conductive paint is a kind of paint with good electrical conductivity using composite particles containing copper, silver, etc. as conductive particles. Conductive coating is a special functional coating developed rapidly along with modern science and technology, and has a development history of about half a century. In 1948, the United States published a patent for making conductive adhesive from silver and epoxy resin, which was the earliest disclosed conductive paint. my country also began to study and apply conductive coatings in the 1950s. In recent decades, conductive coatings have been applied in various military and civilian industrial fields such as electronics, electrical appliances, aviation, chemical indust...

AI Technical Summary

Problems solved by technology

[0005] At present, the electromagnetic shielding effect of the existing conductive coating cloth is average, and the influence of the external electromagnetic field cannot be avoided, the raw materials are not evenly dispersed, and the sticking effect is not good at the same time.
