Building decoration plate with heat insulation and reflection functions and preparation method

Abstract

The invention relates to a building decoration plate with heat insulation and reflection functions and a preparation method. The building decoration plate with the heat insulation and reflection functions comprises a basic material layer, a bottom coating and a surface coating. The basic material layer is any one of an inorganic board, a PVC board and a galvanized board. The preparation method includes the steps that the basic material layer is coated with the bottom coating and the surface coating in sequence, wherein coating of the bottom coating is coating of one or more of a UV penetrating bottom, UV filling putty, UV roller-painting sanded bottom, a UV roller-painting spray front roller, a UV covering white bottom, a UV adhesion bottom, a UV covering white bottom and a self-drying white bottom; coating of the surface coating sequentially includes coating of UV heat-insulating and reflecting colored paint and coating of UV heat-insulating and reflecting varnish; the total coating amount of the UV heat-insulating and reflecting coating is 40-100 g / m<2>; and a curing light source is an LED / UV light source or a UV light source formed by combining one to two gallium lamps with 0-2 mercury lamps. The building decoration plate with the heat insulation and reflection functions has strong cooling and heat insulating functions, no solvent release occurs in the coating process, and the building decoration plate is beneficial for the physical health of construction persons accordingly.

Description

technical field [0001] The invention relates to the field of building decoration boards, in particular to a building decoration board with heat insulation and reflection function and a preparation method. Background technique [0002] Summer is hot and hot, objects are baked and exposed to the sun, and the surface temperature of objects rises, and buildings are no exception, which will bring a lot of trouble to people's work, life and storage of objects. Building insulation has become the focus of heat insulation and cooling, including factories, buildings, bungalows, grain depots, etc. In the field of construction, due to the huge annual energy consumption of buildings, building insulation and energy conservation are one of the key points of energy conservation in my country. Thermal insulation materials have become the main product of building energy saving, and there are many examples of using environmental protection and energy saving coating material technology in archit...

Problems solved by technology

However, due to the poor scrub resistance of the heat-insulating coatings used in traditional architectural decorative panels, the coating will change color and fall off after a short period of time, and the glass curtain wall or tile film will bring light pollution, increase the weight of the building, and have potential safety hazards.
