Embodiment 1

[0018] Weighing in parts by weight, 30 parts of water, 1 part of OP-10, 2 parts of dioctyl phthalate, 35 parts of flame retardant (diethylphosphinate aluminum, melamine, polyphosphoric acid Ammonium, rutile titanium dioxide, calcium carbonate, talcum powder, and dipentaerythritol are mixed according to the mass ratio of 2:2:2:1:0.5:0.5:1) and put into the grinding and dispersing machine for grinding for 2 hours; then add 25 acrylate Emulsion, 7 parts of low molecular weight polyethylene wax (2000-3000), disperse at high speed (1200r / min) for 30 minutes to get the coating.

Embodiment 2

[0020] Weighing in parts by weight, 35 parts of water, 1 part of OP-10, 1 part of dioctyl phthalate, 38 parts of flame retardant (diethylphosphinate aluminum, melamine, polyphosphoric acid Ammonium, rutile titanium dioxide, aluminum hydroxide, zinc borate, and dipentaerythritol are mixed according to the mass ratio of 2:2:2:1:0.5:0.5:1) and put into the grinding and dispersing machine for grinding for 2 hours; then add 20% acrylic acid Ester emulsion, 5 parts of chlorinated paraffin, dispersed at high speed (1200r / min) for 30 minutes to obtain the coating.

Embodiment 3

[0022] Weighing in parts by weight, 33 parts of water, 1 part of OP-10, 1 part of dioctyl phthalate, 35 parts of flame retardant (diethylphosphinate aluminum, melamine, polyphosphoric acid Ammonium, rutile titanium dioxide, activated clay, basic zinc carbonate, and dipentaerythritol are mixed according to the mass ratio of 2:2:2:1:0.5:0.5:1) and put into the grinding and dispersing machine for grinding for 2 hours; then add 24 Parts of acrylate emulsion, 6 parts of low molecular weight polyethylene wax (2000-3000), disperse at high speed (1200r / min) for 30 minutes to obtain the coating.

Abstract

The invention discloses an environment-friendly varnished wire or cable flame-retardant paint. The environment-friendly varnished wire or cable flame-retardant paint comprises, by weight, 30 to 40 parts of water, 0.5 to 1 part OP-10, 0.5 to 2 parts of dioctyl phthalate, 30 to 40 parts of a flame retardant, 10 to 34 parts of acrylate emulsion and 5 to 7 parts of an auxiliary agent. According to a preparation method, water is adopted to replace an organic solvent, so that problems in the prior art that fire hazard danger, human injury, and environment pollution may be caused by solvent volatilization in solvent type paint production and construction process; the advantages are that: cost is low, construction is convenient, and the flame resistance represented by charing degree is much higherthan that required in industry standards.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environment-friendly flame-retardant coating for enameled wires or cables. Background technique [0002] Enameled wire or cable is the main raw material of motors, electrical appliances and household appliances. With the rapid development of various industries, higher requirements are put forward for enameled wire, wire and cable: such as ensuring its flame Its oil resistance, salt resistance, moisture resistance, bending resistance, and cold and heat cycle resistance have relatively high requirements. [0003] Most of the currently used coatings are still solvent-based, and the newly developed water-based coatings either have poor flame retardancy or their adhesion or bending resistance or cold and heat cycle resistance do not meet the requirements, which limits their practical application. application. The invention is a new type of coating which can not only meet the gen...
