Water transparent heat insulation paint and preparation method thereof

Abstract

The invention discloses a water transparent heat insulation paint, containing the following components by weight percent: 50-80% of watercraft acrylic resin, 10-40% of nano sizing agent, 1-10% of solvent and 1-3% of assistant. The watercraft acrylic resin as main resin has the function of realizing physical performances such as hardness, adhesive attraction, resistance to acid and alkali and the like, and the nano sizing material as functional filler mainly realizes heat insulation function. The invention also discloses a preparation method of the watercraft transparent heat insulation paint.The paint of the invention has high visible light transmittance and excellent heat insulation effect, can be rapidly solidified at room temperature with convenient and simple construction, simple production technology and low production cost and is applicable to promotion and application in large scale.

Description

technical field [0001] The invention relates to the technical field of functional coatings, in particular to a water-based transparent heat-insulating coating that can be used for heat-insulating treatment of architectural glass, automobile glass and transparent shading panels and a preparation method thereof. Background technique [0002] The area of ​​doors and windows accounts for about 30% of the building's external maintenance structure area, and its energy dissipation accounts for 2 / 3 of the total building energy consumption, of which heat transfer loss is 1 / 3, which is the weakest part of building energy loss. Statistics show that the energy lost through glass accounts for 80% of the energy loss of doors and windows, so it is extremely necessary to prevent indoor energy from radiating outward through windows. At the same time, since the window is the channel for heat to enter and exit the building, the heat radiation of the sun through the window heats the room, which...

AI Technical Summary

Problems solved by technology

Among them, the low-emissivity coated glass reduces the radiation energy entering the room by reflecting the energy of the near-infrared band of sunlight. In addition, it also has a low heat transfer coefficient, so it can effectively reduce the entry and exit of far-infrared radiation energy indoors and outdoors. It has high visible light transmittance and good energy-saving effect. It is a relatively advanced energy-saving method for glass; however, its high cost limits its large-scale application and promotion.

Solar control coated glass and glass film obtain better energy-saving effect by sacrificing more visible light transmittance, which affects indoor lighting requirements to a certain extent

Insulating glass and vacuum glass mainly achieve the purpose of heat preservation by reducing the heat transfer coefficient of the indoor and outdoor sides, but they cannot effectively block the entry of solar radiation energy. Generally, they must be combined with coated glass to achieve the heat insulation effect of glass.
