Embodiment 1

[0013] A method for producing heat-storing gypsum wall materials. First, add paraffin (with a particle size of about 2mm) and 55% water by weight of the cementitious material to the cementitious material: high-strength gypsum, fly ash and cement, and then Stir evenly to form a slurry, then inject the slurry into a mold, and cast it into a finished gypsum wall material, and after the finished gypsum wall material is solidified, it is demoulded and dried.

[0014] The proportioning of described cementitious material is by its weight percentage:

[0015] High-strength gypsum 60%;

[0016] Fly ash 20%;

[0017] Cement 3%;

[0018] Paraffin 17%.

Embodiment 2

[0020] A method for producing heat-storing gypsum wall materials. First, add paraffin (with a particle size of about 2mm) and 55% water by weight of the cementitious material to the cementitious material: high-strength gypsum, fly ash and cement, and then Stir evenly to form a slurry, then inject the slurry into a mold, and cast it into a finished gypsum wall material, and after the finished gypsum wall material is solidified, it is demoulded and dried.

[0021] The proportioning of described cementitious material is by its weight percentage:

[0022] High-strength gypsum 70%;

[0023] Fly ash 10%;

[0024] Cement 3%;

[0025] Paraffin 17%.

Embodiment 3

[0027] A method for producing heat-storing gypsum wall materials. First, add paraffin (with a particle size of about 2mm) and 55% water by weight of the cementitious material to the cementitious material: high-strength gypsum, fly ash and cement, and then Stir evenly to form a slurry, then inject the slurry into a mold, and cast it into a finished gypsum wall material, and after the finished gypsum wall material is solidified, it is demoulded and dried.

[0028] The proportioning of described cementitious material is by its weight percentage:

[0029] High-strength gypsum 65%;

[0030] Fly ash 12%;

[0031] Cement 3%;

[0032] Paraffin 20%.

Abstract

The invention discloses a production method of a heat accumulation gypsum wall body material, relating to a gypsum wall body material and solving the problem of poor energy saving effect of the conventional building wall body thermal insulation material. The production method comprises the steps of: firstly, adding paraffin wax and water as phase change energy accumulation materials in high-strength gypsum, pulverized fuel ash and cement, then uniformly stirring into slurry, injecting the slurry into a die, pouring into a gypsum wall body material product, demoulding and drying after the gypsum wall body material product is solidified. The heat accumulation gypsum wall body material comprises the following components in percent by weight: 60-70 percent of high-strength gypsum, 10-20 percent of pulverized fuel ash, 3 percent of cement and 8-20 percent of paraffin wax (with grain size of about 2mm). The heat accumulation gypsum wall body material produced by the invention is used for building wall body thermal insulation, can be used for regulating indoor temperature, and is better in energy saving effect.

Description

technical field [0001] The invention relates to a gypsum wall material, in particular to a gypsum wall material with heat storage function. Background technique [0002] At present, in terms of building energy saving, the building wall insulation materials promoted and applied in our country can only play a role in thermal insulation of buildings, and cannot absorb heat and store it, and release it when needed, and cannot regulate the interior of the building. temperature, the energy-saving effect is unsatisfactory. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, provide a production method of heat storage gypsum wall material, and solve the problem of poor energy-saving effect of existing building wall insulation materials. [0004] Task of the present invention is achieved through the following technical solutions: [0005] A production method of heat storage gypsum wall material, characterized ...
