Problems solved by technology

However, real stone paint is often used on the exterior walls of buildings, especially on the exterior walls of large buildings. The area that is irradiated by sunlight every day is huge, while the conventional real stone paint has low reflectivity to sunlight and absorbs too much light. Can lead to poor thermal insulation of building exterior walls

preparation example Construction

[0041] The preparation steps of the surface-modified artificial sand are as follows: first, 25ml of coupling agent (isopropyl tris(dioctyl phosphate acyloxy) titanate) is added to 73mL of alcohol, fully mixed, and then Add 5.2 mL of bishydroxyethylamine dropwise to the above solution, disperse for 35 minutes, and prepare component I. Then prepare component II, 1.4mL sulfuric acid (analytical grade), 9mL alcohol, 0.9mL water are evenly mixed. Then slowly add component II to component I dropwise, fully disperse for 25 minutes, then place it for 3 hours, irradiate the liquid in the beaker with a laser pointer, and confirm that a sol has been formed by observing the Tyndall effect. Add 70g of sintered sand produced by Shunfeng Group to the above sol, disperse to make it fully wet, under the action of capillary force, the sol particles are deposited on the surface of the sintered sand, and the sintered colored sand leaves the sol during the natural drying process of water and alcoh...

Abstract

The invention discloses reflective heat insulation stone-like paint and a preparation method thereof, and belongs to the technical field of paint production. The stone-like paint comprises deionized water, cellulose, organic bentonite, a multifunctional auxiliary agent, a silicone-acrylic emulsion, a dispersing agent, an antifreeze agent, a film-forming aid, a defoamer, a preservative, a thickener, natural colored sand, modified artificial sand and hollow glass microbeads and / or glass fiber cotton, wherein white-series color sand accounts for 30-40% of the weight of the natural colored sand ofdifferent particle size. The prepared reflective heat insulation stone-like paint is applied to decoration and protection of building outer walls, and through adjustment of the natural colored sand and matching of the modified artificial sand and hollow glass microbeads and / or glass fiber cotton, a coating obtained after the stone-like paint is cured has good effects of reflection and heat insulation.

Description

technical field [0001] The invention belongs to the field of fine chemicals, in particular to the field of coatings, in particular to a reflective heat-insulating real stone paint and a preparation method thereof. Background technique [0002] Real stone paint is a kind of paint with a decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors, and it is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. The buildings decorated with real stone paint have natural and real natural color, which gives people elegant, harmonious and solemn aesthetic feeling. It is suitable for indoor and outdoor decoration of all kinds of buildings. Especially when it is decorated on curved buildings, it is vivid and lifelike, and has an effect of returning to nature. In recent years, real stone paint has gradually become one of the mainstream varieties of architectural coatings. However, real s...
