Problems solved by technology

However, more than 80% of the solar reflection and heat insulation coatings currently used in the market are white, which cannot meet the decoration requirements of buildings in different colors, and the oxygen index of the coating film is lower than 27, and the flame retardant and fireproof performance is poor.

Embodiment Construction

[0022] The present invention is further described in detail below in conjunction with specific examples, a kind of gray heat-insulating flame-retardant exterior wall paint, and each component in its formula is constituted as follows:

[0023]

[0024] The measurement units of the above components are in mass fraction / %;

[0025] The preparation process of gray heat-insulating flame-retardant exterior wall coating is as follows:

[0026] Add deionized water into the dispersion tank, add dispersant 5040, wetting agent X-405, defoamer A36, multifunctional additive AMP-95, preservative EXL and ethylene glycol under medium speed stirring for pre-dispersion, and then Add ALTIRIS infrared reflective pigment and melamine-modified ammonium polyphosphate, disperse at high speed for 30 minutes, grind to a fineness of 40 μm with a sand mill to form a slurry, put the slurry into the paint mixing tank, add surface UV curing under medium-low speed stirring Elastic acrylic emulsion, silic...

Abstract

The invention discloses a grey heat-insulation flame-retardant external wall paint. A surface ultraviolet-curing elastic acrylic emulsion and modified silica sol are compounded to obtain a film forming material, an ALTIRIS infrared reflection pigment is used as a white pigment, a compound black color paste is used as a coloring pigment, and melamine-modified ammonium polyphosphate is used as a flame retardant; and under the cooperation of deionized water and multiple assistants, dispersion, grinding, blending, and color matching are carried out to prepare the grey heat-insulation flame-retardant external wall paint. The compound black color paste is prepared by the following steps: compounding iron oxide red, titanium-chrome yellow and phthalocyanine blue into a black pigment, mixing with a proper amount of deionized water, dispersing agent, wetting agent and defoaming agent, dispersing and grinding. The invention has the characteristics of grey color, high solar reflection factor, cracking resistance due to high elasticity, heat insulation and control, flame retardancy and fire resistance, is suitable to be sprayed as a veneer paint for EPS, XPS and polyurethane hard foamed external wall external-thermal-insulation systems, and has wide popularization prospects.

Description

Technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a gray heat-insulating and flame-retardant exterior wall coating. Background technique [0002] At present, organic insulation materials such as EPS board, XPS board, and PU rigid foam occupy more than 80% of the external wall insulation market. Although organic thermal insulation materials have the characteristics of small thermal conductivity and good thermal insulation performance, their fireproof performance is poor. In order to reduce the fire accidents caused by the thermal insulation layer of the building's external wall, the current building standards clearly stipulate that the external thermal insulation materials for civil buildings should adopt products with combustion performance above B1. Generally, the combustion performance of organic thermal insulation materials is below B2 level. After years of technological transformation, it can reach the B1 lev...
