Embodiment

[0014] The steps of preparing a building board capable of regulating indoor humidity are as follows:

[0015] (1) preparation mass percentage concentration is the CaCl of 30% 2 solution;

[0016] (2) According to the weight ratio of polymer resin:salt solution=1:15, add an appropriate amount of polymer resin to the salt solution, stir to form a gel, and obtain the humidity-controlling material;

[0017] (3) mix cement slurry (water-cement ratio is 0.53) and perlite aggregate by volume ratio of 1:1, stir evenly, obtain cementitious material;

[0018] (4) Mix the humidity-adjusting material and the cement in a weight ratio of 1.5:1, stir quickly and evenly, pour into the mold, and place it in an environment with a temperature within the range of 20±32 and a relative humidity between 70% and 80%. , 48 hours of health preservation;

[0019] (5) After the health preservation is completed, demould and form.

[0020] Put the generated building boards in different relative humidit...

Abstract

The invention discloses a formula of a building plate capable of regulating indoor humidity and a preparation method thereof, belonging to the field of building materials. The invention can solve the problems of small moisture storage capacity and water condensation on the surface of similar materials. The preparation method is as follows: prepare a hygroscopic salt solution with a mass percent concentration of 10% to 40%; add an appropriate amount of polymer resin to the salt solution according to a weight ratio of 1:10 to 20 between the polymer resin and the salt solution, and stir to form a gel , to obtain the humidity-conditioning material; prepare the cementing material according to the volume ratio of the cementing agent and the aggregate 1:1-2; mix the humidity-conditioning material and the cementing material according to the weight ratio of the humidity-conditioning material and the cementing material 1:0.5-1, and stir quickly and evenly Finally, pour it into the mold, and place it in an environment with a temperature in the range of 15-30°C and a relative humidity of 70%-80%, and keep it healthy for 48 hours; The products prepared by the present invention are suitable for use on the interior surfaces of building envelopes.

Description

technical field [0001] The invention relates to a formula and a preparation method of a building plate capable of regulating indoor humidity, belonging to the field of building materials. Background technique [0002] At present, the commonly used humidity-regulating materials used in building boards with humidity-regulating functions are mainly divided into two categories. One is to use porous media such as wood, gypsum, and zeolite as humidity-regulating materials, and the other is to use hygroscopic salts as humidity-regulating materials. For building panels that use porous media as humidity-regulating materials, since the moisture in the panels mainly exists in the capillary pores in gaseous form, the moisture storage capacity is generally small, so it can only be used as an auxiliary humidity-regulating method; For building panels of wet materials, because the hygroscopic salt is directly attached to the substrate such as concrete, the salt becomes a salt solution after...
