Reflecting thermal-insulation paint

Abstract

The invention relates to the field of paints, in particular to a reflecting thermal-insulation paint, which comprises the following components in percentage by weight: 40 to 60% of fluorocarbon resin, 0.2 to 1.5% of fumed silica, 8 to 16% of aid, 15 to 30% of pigment, 6 to 20% of hollow glass microspheres, and 5 to 15% of solvent. The reflecting thermal-insulation paint disclosed by the invention is easy to prepare and use in construction, high in weather resistance and stain resistance, high in film density, small in dry film thickness and good in thermal-insulation effect, the solar light reflection rate and hemispherical reflection rate of the paint can keep stable for a long time together with reflecting and thermal-insulation performance. The paint can prevent heat from being transmitted to the interior of a vehicle, which not only saves energy, but also reduces the temperature of the interior and increases the comfort of the vehicle.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a reflective heat-insulating coating. Background technique [0002] With the improvement of people's living standards, cars have entered thousands of households and become a necessary means of transportation for cities and families. While automobiles bring convenience and comfort to people, they also cause energy consumption and environmental pollution. Due to the shortage of oil energy in the world and the rise of oil prices, the energy consumption of automobiles has become the focus of people's increasing attention. At the same time, the environmental pollution caused by automobile exhaust emissions has attracted people's attention. Among the 6 main pollution components that cause air pollution, 4 The pollution caused by automobile exhaust emissions accounts for 60% to 70% of air pollution. Automobile exhaust has replaced industrial waste gas as the primary source of air pollution. Th...

Problems solved by technology

[0003] The upsurge of research on reflective heat-insulating coatings at home and abroad is mainly to reduce the temperature of the outer surface of buildings and industrial storage tanks. There are few studies on reflective heat-insulating coatings for automobiles, and even less research on reflective heat-insulating coatings for car roofs.

The 2003 patent CN100381518C and the 2007 patent CN101195725 disclosed a production method for heat-insulating coatings for vehicles, but ceramic microbeads were used as fillers, the specificity of the product was large, and the coating area was low, which was not conducive to lightweight, and its heat-insulating effect Poor; CN101121858 discloses a heat-insulating coating that reflects solar heat reflection rays. When the dry film thickness is 0.3-0.5mm, the total reflectivity to heat reflection rays can reach 85-90%, which can effectively prevent the sun's heat radiation. But its dry film thickness is still thick, not ideal
