Abstract
The invention discloses quick-dry heat-reflection and heat-insulation exterior wall paint. The quick-dry heat-reflection and heat-insulation exterior wall paint is prepared from the following raw materials in parts by mass: 10 to 16 parts of hydroxyl methyl bisphenol A modified epoxy resin emulsion, 15 to 20 parts of acrylic acid modified organic silicon resin emulsion, 0.4 to 0.7 parts of ceramic black, 0.6 to 0.9 part of barite powder, 1 to 3 parts of HMDI (Hexamethylene Diisocyanate) and 9 to 16 parts of water. A preparation method of the quick-dry heat-reflection and heat-insulation exterior wall paint comprises the following steps: (1) adding the hydroxyl methyl bisphenol A modified epoxy resin emulsion, the acrylic acid modified organic silicon resin emulsion and the water into a stirrer, wherein the stirring speed is 450r / min to 490r / min and the stirring time is 35min to 50min; (2) adding the ceramic black, the barite powder and the HMDI, wherein the stirring speed is 430r / min to 460r / min; continually stirring and dispersing; (3) dispersing until the fineness is 45mum to 50mum and discharging to obtain a finished product.
Description
technical field [0001] The invention relates to the field of coatings, in particular to a heat-reflecting and heat-insulating exterior wall coating and a preparation method thereof. Background technique [0002] Architectural reflective heat insulation coating is to isolate the solar energy by reflecting visible light and infrared light, so as to achieve the purpose of heat insulation. A high reflectivitycoating prepared by selecting suitable functional fillers such as resin, ceramicpowder, metal or metal nano-oxide materials. This kind of coating has the dual functions of decoration and heat insulation. It is a functional coating and is mainly used for reflective heat insulation of roofs and walls in construction projects. [0003] The architectural reflective heat-insulating coatings currently used for exterior walls have shortcomings such as insufficient quick-drying properties. Contents of the invention [0004] Aiming at the problems existing in the prior art, the...
