preparation example Construction

[0034] The preparation method of the present invention is as follows:

[0035] 1. Add acrylate elastic emulsion, ethylene glycol, leveling agent, dispersant, film-forming aid, and defoamer into the mixing container according to the weight of the formula components, and stir for 5 minutes;

[0036] 2. Gradually add flame retardants (ammonium polyphosphate, melamine, aluminum hydroxide, zinc borate, dipentaerythritol), fillers and colorants according to the weight parts of the formula components under stirring, and then grind to a particle size of less than 90 μm ;

[0037] 3. Add the thickener according to the parts by weight of the formula components under stirring, then filter through a pipeline filter and fill.

Embodiment 1

[0040] 1. Take 100 parts of acrylate elastic emulsion, 0.6 parts of ethylene glycol, 1.2 parts of A-900 leveling agent, 0.2 parts of DA-01 dispersant, 1.2 parts of dodecyl alcohol ester film-forming aid, 8034A defoamer ( 1:1 water mixture) 2.5 parts and 25 parts of water were poured into the disperser and stirred for 5 minutes;

[0041] 2. Add 50 parts of flame retardant ammonium polyphosphate, 20 parts of melamine, 7 parts of aluminum hydroxide, 4 parts of zinc borate, 14 parts of dipentaerythritol, 7 parts of filler heavy calcium carbonate and 15 parts of colorant titanium dioxide under stirring , ground to a fineness of less than 90 μm;

[0042] 3. Add 0.3 part of TR-612 thickener under stirring, then filter through pipeline filter and fill.

Embodiment 2

[0044] 1. Take 100 parts of acrylate elastic emulsion, 1.8 parts of ethylene glycol, 3.5 parts of A-900 leveling agent, 0.8 parts of DA-01 dispersant, 3.0 parts of dodecyl alcohol ester, 8034A defoamer (1:1 water Pour 5.5 parts of mixed liquid) and 50 parts of water into the disperser and stir for 5 minutes;

[0045] 2. Add 55 parts of flame retardant ammonium polyphosphate, 20 parts of melamine, 10 parts of aluminum hydroxide, 5 parts of zinc borate, 20 parts of dipentaerythritol, 15 parts of filler heavy calcium carbonate and 25 parts of colorant titanium dioxide under stirring , ground to a fineness of less than 90 μm;

Abstract

The invention discloses a fire retardant coating and a preparation method thereof, wherein, the fire retardant coating comprises base materials and auxiliary materials. The preparation method comprises the following steps of: selecting water-soluble polyacrylic resin elastic emulsion and a variety of assistants; taking water as diluent, adding flame retardants such as ammonium polyphosphate, melamine, aluminum hydroxide, zinc borate, dipentaerythritol and the like, as well as auxiliary fillers and colorants; then blending, grinding and filtering, and acquiring the fire retardant coating. The fire retardant coating has good performance of flame retarding, is free of organic solvent volatilization in the curing process; with non-toxic and environmental protecting formula, the formed film has better elasticity and adhesion and releases no toxic and harmful gases such as halogens when on fire, thus meeting the environmental protecting requirements.

Description

technical field [0001] The invention relates to a polymer coating and a preparation method thereof, in particular to a fireproof coating and a preparation method thereof. Background technique [0002] Fire-resistant coatings are generally used for coating the surfaces of various cables and combustible plastics that require fire protection, and can form a coating film with fire-retardant protection and certain decorative effects on the surfaces of various cables and combustible plastics. For example, the Chinese patent application number 200610053130.7 discloses a "manufacturing method of water-based cable fireproof coating", and its raw material formula is composed of water, 44.2% to 29.9%; emulsifier OP-10, 0.6% to 0.9% ; Dioctyl ester, 1% ~ 2%; 52 degrees chlorinated paraffin, 6% ~ 8%; ammonium polyphosphate, 17% ~ 19%; melamine, 8% ~ 10%; dipentaerythritol, 8% ~10%; rutile titanium dioxide, 2.5%~3.5%; wollastonite powder, 1%~2%; acrylate elastic emulsion, 12%~15%.
