Self-controlled phase-variable energy-storage economical material and its production

Abstract

A self-controlling phase-variable and energy-storage material and its production are disclosed. The material consists of cement 25-35 proportion, fly ash 5-8 proportion, phase-variable powder containing paraffin 20-30 proportion, fined slag powder 4-8 proportion, rubber powder 3-6 proportion, fiber 1-3 proportion and light aggregate 20-30 proportion. The light aggregate can be glass micro-pearl or polyphony grain, which is distributed with formaldehyde decomposing agent. It can release heat-energy storage by medium phase variation, improve indoor heat circulation, properties of thermal-insulation, heat-storage and wet breathing and have on base leakage.

Description

technical field [0001] The invention relates to a thermal insulation material for a building wall and a production process thereof. Background technique [0002] The development of modern buildings to high-rise buildings requires the envelope structure to be made of lightweight materials. However, the heat capacity of ordinary lightweight materials is small, resulting in large fluctuations in indoor temperature. This not only makes the indoor thermal environment uncomfortable, but also increases the air-conditioning load, resulting in an increase in building energy consumption. my country's building energy consumption accounts for 27% of the country's total energy consumption. In order to implement the national policy of energy saving, consumption reduction and sustainable development, the Ministry of Construction proposed a three-step energy saving standard of 65% for new buildings. To meet the above standards, it is necessary to improve the traditional wall insulation m...

Problems solved by technology

[0029] The purpose of the present invention is to provide a self-controlled phase change energy storage energy-saving material and its production method, which mainly solves the problem that the traditional wall insulation material has a low latent heat value and is difficult to achieve 65% of building energy saving; Leakage, traditional wall insulation materials have low compressive strength and are easily affected by climate change to produce expansion and contraction cracks, resulting in poor aging resistance of materials, loss of cohesive force and falling off, leading to failure of the entire building insulation system, and even causing safety hazards; At the same time, it solves the problems of poor fire resistance, complicated construction procedures and high process cost of traditional thermal insulation materials, which cannot meet the requirements of energy conservation and environmental protection.
