AI Technical Summary

Problems solved by technology

There are four main problems in my country's energy development: ①The per capita energy possession and reserves are low; ②The energy structure is still dominated by coal; ③The distribution of energy resources is uneven; ④The energy utilization efficiency is low.
The development of building energy-saving materials in my country began in the early 1990s. At the beginning, there were relatively few insulation materials used for building energy-saving. After more than 20 years of development, a production and technical system of insulation materials with a certain scale and a complete range has been formed. , but there is still a big gap with industrially developed countries. Since most buildings in our country have not adopted thermal insulation measures, the thermal insulation performance of building wall structures is generally low.

Abstract

The invention relates to the field of heat preservation and energy saving of buildings, in particular to a novel thin-layer building-external-wall heat preservation system and a preparing method and application thereof. The heat preservation system sequentially comprises an alkali-resistant sealing primer layer, a heat-preservation putty thermal insulating layer, an energy-storing temperature-regulating heat releasing layer, a sealing primer layer, a cooling-coating middle coating and a cooling-coating face coating from inside to outside. The novel thin-layer building-external-wall heat preservation system is characterized in that three heat-insulation principles (the reflection-type principle, the obstructing-type principle and the radiation-type principle) are integrally applied and further optimally combined. In addition, the performance of all components of the novel thin-layer building-external-wall heat preservation system is further optimized, and the overall performance is remarkably improved.

Description

technical field [0001] The invention relates to the field of building heat preservation and energy saving, in particular to a novel thin-layer building exterior wall heat preservation system and its preparation method and application. Background technique [0002] Since the outbreak of the oil crisis in the 1970s, people have gradually realized the importance of energy. In the 21st century, the three traditional energy sources of oil, coal, and natural gas are becoming increasingly exhausted worldwide, and the energy problem in our country is even more serious. There are four main problems in my country's energy development: ① low per capita energy possession and reserves; ② coal-based energy structure; ③ uneven distribution of energy resources; ④ low energy utilization efficiency. Therefore, scientific researchers have proposed not only to develop new energy sources, but also to save energy vigorously to ensure the sustainable development of energy. In all energy consumpt...
