Stone thermal insulating composite panel

Abstract

The invention relates to a stone thermal insulating composite panel which comprises a stone surface layer and is characterized by also comprising a thermal insulating layer and a substrate, wherein a plurality of fine closed holes are distributed inside the thermal insulating layer; the substrate is arranged between the stone surface layer and the thermal insulating layer; and the stone surface layer, the substrate and the thermal insulating layer are integrally fixed by a binding agent. The stone thermal insulating composite panel has the advantages of simple structure, good thermal insulating effect, light weight, convenient installation, good weatherability and high surface rigidity. The stone thermal insulating composite panel of the invention can improve the indoor thermal insulating effect and reduce the energy consumption.

Description

technical field [0001] The invention relates to a building material, in particular to a stone thermal insulation composite board installed on the wall of a building. Background technique [0002] With the gradual consumption of non-renewable energy, countries around the world put forward energy-saving slogans and programs in different forms. For example, in the construction industry, all modernized houses are required to be energy-saving houses. In modern houses, the walls of most houses are equipped with inorganic boards or natural stone boards. Although the inorganic boards are light and beautiful, and the natural stone boards are thick and elegant, they can beautify the house, but the hardness of the inorganic boards is low. Affected by environmental factors, there will be great changes. The specific performance is poor durability, poor weather resistance, and relatively short color retention time; natural stone panels are high in cost and heavy in weight. If natural sto...

In modern houses, the walls of most houses are equipped with inorganic boards or natural stone boards. Although the inorganic boards are light and beautiful, and the natural stone boards are thick and elegant, they can beautify the house, but the hardness of the inorganic boards is low. Affected by environmental factors, there will be great changes. The specific performance is poor durability, poor weather resistance, and relatively short color retention time; natural stone panels are high in cost and heavy in weight. If natural stone panels are used as stone curtain walls, in addition to the above In addition to the disadvantages of natural stone panels, there are thicker natural stone panels (generally, the thickness of natural stone is 20-25mm), and the quality is heavy. For example, the comprehensive weight of stone curtain walls above 25mm is 70-90 kg / m 2 If it is installed on the wall, it must be fixed on the wall with a steel structure keel, which greatly increases the load and cost of the house, and the safety of the house will also be affected.

The biggest defect of the above two boards is poor thermal insulation function, which is not conducive to making the house meet the energy-saving standard.
