Problems solved by technology

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

Abstract

The invention discloses a scratch-resistant outdoor powder paint which is composed of the following raw materials in parts by weight: 5-8 parts of modified sericite, 10 parts of silicon dioxide, 8-15 parts of modified nano tin tungsten oxide, 5 parts of barium sulfate, 7 parts of titanium dioxide, 1-3 parts of dispersing aid, 1-3 parts of leveling agent, 0.05-1 part of defoaming agent, 1 part of polytetrafluoroethylene wax, 30 parts of water-based polyurethane resin and 30 parts of organic silicon resin. The paint is suitable for heat insulation on the surfaces of building glass, vehicle glass and cement, can shield ultraviolet and infrared light, and has the advantages of favorable heat-insulating property, favorable scratch resistance, stable coating performance and simple preparation technique.

Description

technical field [0001] The invention relates to a scratch-resistant outdoor powder coating, which belongs to the field of chemical coatings. Background technique [0002] Among all kinds of energy consumption, building heating and air conditioning consume a considerable proportion, and doors and windows are important channels for sunlight to enter the room. At present, the main energy-saving glass used is low-emissivity glass (Low-E) and solar control coated glass. The former has good photothermal performance, and the main function of the latter is to absorb and reflect solar radiation energy, but its visible light transmittance is low. At present, low-E coated glass on the market is mainly produced by magnetron sputtering and float online chemical vapor deposition (CVD), but the process is complex, requires high equipment, and is expensive, making it difficult to market. [0003] Because the energy of ultraviolet rays can cause skin aging and even easily lead to skin canc...
