Reflective insulation nano-modified quartz sand and preparation method thereof

Abstract

The invention discloses reflective insulation nano-modified quartz sand which comprises, in weight percentage, 5%-35% of butyl titanate, 20%-75% of solvents, 1%-8% of chelating agents, 0.2%-5% of pH (potential of hydrogen) regulators, 0.2%-5% of water and 15%-70% of quartz sand. The preparation method includes the steps: firstly, adding the butyl titanate into the solvents, stirring the butyl titanate, sufficiently dissolving the butyl titanate, dripping the chelating agents and stirring the chelating agents to obtain solution A; secondly adding the pH regulators and the water into the solvents and stirring the pH regulators and the water to obtain solution B; thirdly, dripping the solution B into the solution A, continuing stirring, and performing standing and aging after stirring to obtain sol C; fourthly, adding the quartz sand into the sol C, stirring the quartz sand, sufficiently wetting the quartz sand, drying the quartz sand after standing and filtering, calcining the quartz sand at high temperature and annealing and cooling the quartz sand to obtain final products. The reflective insulation nano-modified quartz sand has the advantages that the reflective insulation nano-modified quartz sand can be applied to really stone paint, and reflective insulation performance is enhanced while coating sand texture cannot be affected.

Description

technical field [0001] The invention relates to a reflection heat insulation material, in particular to a reflection heat insulation nano-modified quartz sand and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the petroleum industry, transportation industry, construction industry, weapon industry, etc., coatings that can make the coated object produce a cooling effect under sunlight have attracted widespread attention. Various solar shielding coatings, heat reflective coatings , space heat insulation coatings, energy-saving thermal insulation coatings and other products are constantly coming out to reduce the surface temperature of equipment exposed to solar radiation, prevent heat conduction, improve the working environment, and improve safety. For example, offshore drilling platforms, oil tanks, and oil transportation in the petroleum industry; surfaces of automobiles, trains, and aircraft in the transportation in...

Problems solved by technology

However, these methods realize the reflection and heat insulation function by adding other functional materials such as titanium dioxide and vitrified microbeads to the textured paint, and the addition of these materials will affect the very important sandy texture effect of the textured paint. The microspheres are also easy to break under the friction and extrusion of the quartz sand filler that produces texture effects during the coating production process and lose their thermal insulation properties, etc.

Therefore, under the comprehensive goal of requiring both high texture effect and high heat insulation effect, the result of this material is not obvious. It is obvious that this technology is still difficult to be well popularized and applied in high texture coatings such as real stone paint.
