Abstract

The invention relates to a thermal insulation mortar material and a preparation method thereof, and particularly relates to a phase-change and energy-storage mortar of ternary composite paraffin/glazed hollow beads, which has good thermal insulation properties and is capable of improving the energy utilization rate and adjusting the indoor temperature, and a preparation method of the phase-change and energy-storage mortar. The phase-change and energy-storage mortar of the ternary composite paraffin/glazed hollow beads is prepared from the following raw materials: 370-380 parts of 42.5-level ordinary portland cement, 30-35 parts of silica fume, 200-240 parts of glazed hollow beads, 420-460 parts of water, 30-50 parts of a styrene-acrylic emulsion, and 600-750 parts of mixed paraffin which is compounded by 3# liquid paraffin, normal tetradecane and solid sliced paraffin of which the melting point is 48-50 DEG C at the ratio of 1 to 2 to 7 in a physical blending manner. Compared with ordinary mortar, the heat retaining property, the crack resistance, the weather fastness and the like of the mortar are improved; the fluctuation range of indoor temperature can also be retarded; the duration of indoor comfort temperature is increased; the living comfortability is improved; energy storage and utilization are achieved by effectively utilizing latent heat of phase change of the phase-change material; and energy sources are saved.

Description

technical field [0001] The invention relates to a thermal insulation mortar material and a preparation method thereof, in particular to a novel ternary composite paraffin / vitrified microbead phase change energy storage mortar with good thermal insulation performance, which can improve energy utilization efficiency and regulate indoor temperature and its preparation method. Background technique [0002] my country is a big country in energy production and consumption. With the acceleration of urbanization and the improvement of people's quality of life, building energy consumption has become the weakness of my country's economic development. Actively improving energy utilization in buildings and implementing building energy conservation can greatly alleviate the shortage of energy in our country and promote the construction and development of our national economy. [0003] Phase change materials are able to absorb heat (coldness) from the environment during their own phase t...
