Aqueous UV (Ultraviolet) photo-curing full-shielding nano transparent heat-insulating coating

Abstract

The invention relates to an aqueous UV (Ultraviolet) photo-curing full-shielding nano transparent heat-insulating coating, comprising the following components in percentage by weight: 30-60% of aqueous UV resin, 5-30% of nano ATO (Arsenic Trioxide) dispersed body, 1-10% of nano LaB6 dispersed body, 1-15% of nano WO3 dispersed body, 2-10% of light initiator and 0.5-1.0% of auxiliary agent. The preparation method comprises the following steps of: agitating and gradually dropwise adding the modified nano ATO, nano LaB6 and nano WO3 dispersed bodies into an aqueous UV pre-polymer; dispersing at a high speed and removing a solvent; and sequentially adding the light initiator, a de-foaming agent, a flattening agent and an accelerating agent, and agitating to prepare the aqueous UV photo-curing full-shielding nano transparent heat-insulating coating. The coating is environment-friendly and is excellent in performance, can be used on the surface of building glass, vehicle glass and resin, and has the very obvious heat insulation performance. The coating can realize automatic assembly line coating and has the advantages of convenience for construction, fast curing peed and high production efficiency.

Description

technical field [0001] The invention relates to functional nano-materials, in particular to a full-shielding solar infrared and ultraviolet full-band, using water-based UV resin as a film-forming material, made of ATO / WO 3 / LaB 6 The invention relates to a transparent heat-insulating paint made of nanocomposite materials and a preparation method thereof, in particular to a transparent heat-insulating paint which can be coated on various glass, plastic, metal and cement surfaces. Background technique [0002] China has nearly 40 billion square meters of buildings, 95% of which are non-energy-efficient buildings. Compared with developed countries with similar climate conditions, my country’s energy consumption per square meter for heating and cooling is about three times that of developed countries, but the comfort level is far inferior to that of people. Therefore, the new national building energy-saving standard stipulates that the energy-saving of new buildings must reach 5...

Problems solved by technology

[0005] Existing transparent heat insulation technologies mostly use ITO and ATO as shielding materials, but these two materials can only shield long-wave near-infrared, and have no obvious barrier to short-wave near-infrared and ultraviolet rays, so the energy-saving effect is limited

[0006] At present, there are many deficiencies in the nano transparent glass thermal insulation coatings on the market in terms of environmental protection, drying speed, coating thermal insulation performance, transparency and application promotion.
