High-reflectivity weather-resistant powder coating material and preparation method thereof

Abstract

The invention discloses a high-reflectivity weather-resistant powder coating material and a preparation method thereof, and belongs to the field of coating materials. The production process comprises:weighing raw material ingredients according to a formula, placing into a mixer, and mixing and stirring; placing the mixture into an extruder, and carrying out melting mixing extrusion; and cooling the extruded sheet-like clinker, pouring the cooled sheet-like clinker into a crusher, grinding, screening to obtain powder, and carrying out packaging warehousing. According to the present invention,the reflectivity of the high-reflectivity weather-resistant powder coating material to ultraviolet long wave and medium waves and infrared rays is up to more than 90%; the high-reflectivity weather-resistant powder coating material has good weather resistance, and is the coating material with characteristics of environmental protection, zero VOC emission, long life, strong adhesion and energy saving; and the high-reflectivity weather-resistant powder coating material has high reflectivity and excellent temperature resistance compared to the conventional powder, such that the color is soft after the coating material is applied to the lamp shade surface; and the high-reflectivity weather-resistant powder coating material has energy saving effect in daily household lamps, industrial and mining enterprises and public lighting facilities.

Description

technical field [0001] The invention relates to a powder coating, in particular to a powder coating with high reflectivity and weather resistance and a preparation method thereof. Background technique [0002] In the past, the surface protection and decoration of the lighting industry usually used electroplating, which has beautiful, diverse, decorative and anti-corrosion properties. With the increasingly fierce market competition and the diversification of consumer demand. The rapid development of the decoration industry and supporting products is driven by the construction industry and real estate development, and consumers' vision and appreciation level are also constantly improving. In public and home decoration, it also emphasizes and pursues unique and different styles and tastes, and pays more attention to the harmony of the overall tone. A single surface electroplating and finishing product can no longer meet the needs of multi-level consumers. As a result, some li...

Problems solved by technology

But at present, the surface of lampshades and other lighting decorations is generally made of spray paint and ordinary powder coating, and its reflectivity is only 85%.

Moreover, as the use time increases, aging, yellowing, deformation, paint peeling, and gradual loss of temperature resistance cause the lampshade to be easily broken, which greatly reduces the service life of the lampshade in the lamp, especially the energy-saving lampshade.
