Abstract

The present invention discloses a high-performance, low-cost, environmentally-friendly novel building wall polymer heat insulation dry-mixed mortar material which is provided with phase change energy storage and thermostat function. The invention is a polymer heat insulation dry-mixed mortar material that introduces the phase change energy storage aggregate of organic phase change material polymer. The invention adopts a two-step technology, namely, first, the highly-stable phase change energy storage aggregate with high heat capacity is manufactured; second, the phase change energy storage aggregate is used to confect the building wall polymer heat insulation mortar by suing the modern concrete dry-mixing technology. The preparation technology is simple, safe and environmentally friendly, and is easy to implement and control, which will help promote the application of industrialization. The building wall polymer heat insulation mortar solves the key technical problem of the combination between organic phase change materials and common building materials and eliminates the compact of organic phase change materials on the mechanical and fire-proofing performances of the buildings. The building wall polymer heat insulation mortar is provided with high cycle working stability, high organic introduction amount of phase change materials, low thermal conductivity coefficient, high thermal storage coefficient, extremely excellent thermal insulation performance and temperature adjustment function.

Description

technical field [0001] The invention relates to a thermal insulation mortar and a preparation method thereof. More specifically, the invention relates to a phase change energy storage type polymer thermal insulation mortar for a building wall and a preparation method thereof, belonging to the field of building energy conservation. Background technique [0002] Building energy conservation is a long-term strategic policy and basic policy formulated by our country, and it is the ultimate goal of sustainable development of resources in our country. In the past 20 years, my country's social and economic development level has achieved world-renowned improvement, and the material living standards of the people have been rapidly improved. However, in terms of building energy efficiency, compared with Western industrial countries, the gap is still very large. The energy consumption per unit building area in my country is three times that of developed countries with similar climate c...
