Water-based thermal-insulation paint for cement encaustic tiles and roofs and preparation method thereof

Abstract

The invention relates to a water-based thermal-insulation paint for cement encaustic tiles and roofs and a preparation method thereof. The water-based thermal-insulation paint for cement encaustic tiles and roofs is prepared by mixing a primer, which has the complex functions of reflecting and radiating solar heat and obstructing heat conduction, and a nano transparent varnish, which has high-light decoration performance and can reflect and transmit infrared rays. Compared with the prior art, under the composite actions of the primer and varnish, the water-based thermal-insulation paint for cement encaustic tiles and roofs has obvious thermal-insulation and cooling effects; and compared with the existing white and light-colored reflection-type thermal-insulation paint for buildings, the water-based thermal-insulation paint for cement encaustic tiles and roofs has the characteristics of multiple color systems, favorable high-light decoration performance, greater temperature difference of thermal insulation, and the like.

Description

Technical field

[0001] The invention relates to a thermal insulation coating for roofs and a preparation method thereof, in particular to a cement colored tile and a water-based thermal insulation coating for roofs and a preparation method thereof. Background technique

[0002] Cement concrete machine-made colored tiles are a new type of building materials products that are burn-free, energy-saving, and resource-recycling, which have emerged in recent years. In the past, solvent-based acrylic paints and water-based paints were often used for high-gloss color decorative finishing, which made the roof heat absorption problem prominent. The domestic thermal insulation coatings for construction are mainly inorganic silicate barrier thermal insulation coatings and reflective thermal insulation coatings that have risen in research and development in recent years. These two types of thermal insulation coatings have good thermal insulation effects. , But they are all white and have a ve...
