Problems solved by technology

[0003] As a kind of building material with porous structure, gypsum building material products have a certain function of moisture absorption and temperature regulation. In recent years, gypsum-based mortar has been developing rapidly because of its greenness and environmental protection, but there are few reports on functional mortar with decoration and intelligence.

Embodiment 1

[0045] The preparation of gypsum-based self-leveling floor materials is as follows:

[0046] Step 1: Preparation of phase change energy storage and heat storage materials. For the preparation method, please refer to the literature: Preparation and Characterization of Paraffin Microcapsule Phase Change Materials [J]. Huang Xiaohong, Ji Zhen, etc., Powder Metallurgy Technology, 2015, 33(5). Weigh 5 parts by weight of the phase-change energy storage heat storage material for subsequent use

[0047] Step 2: Grind the color-changing silica gel, pass through a 200-mesh sieve, and weigh 5 parts by weight for later use;

[0048] Step 3: Mix 20 parts by weight of the desulfurized gypsum clinker with the low-temperature phase-change energy storage and heat storage material prepared in step 1 and set aside;

[0049] Step 4: The premix obtained in step 3 is divided into 80 parts by weight of desulfurized gypsum clinker, 5 parts by weight of discolored silica gel powder in step 2, and 2 ...

Embodiment 2

[0061] The method for preparing the gypsum-based self-leveling floor material is the same as in Example 1, except that:

[0062] Anhydrite (purchased from Nanjing Special Non-metallic Materials Co., Ltd.) is 100 parts by weight, Portland cement is 5 parts by weight, K 2 SO 4 2 parts by weight, the water reducer is 0.2 parts by weight of polycarboxylate water reducer, the redispersible latex powder is 3 parts by weight, the water retaining agent is 0.05 parts by weight, and the filler is 50 parts by weight (70-90 mesh). Test the standard consistency water consumption of the above mortar, prepare slurry according to the standard consistency water consumption, and lay it with a laying thickness of 5mm.

[0063] The gypsum-based self-leveling mortar produced in Example 2 is subjected to a performance test according to the test method described in Example 1, and the results are shown in Table 2 below:

Abstract

The invention discloses a gypsum-based self-leveling floor material. Relative to 100 parts by weight of gypsum, the content of allochroic silicagel is 1 to 15 parts by weight, the content of a phase change energy storage and heat storage material is 5-20 parts by weight, the content of a porous mineral material is 1-5 parts by weight, the content of a water reducing agent is 0.25-1 part by weight,the content of latex powder is 0.5-4 parts by weight, the content of a water retaining agent is 0.02-0.12 part by weight, and the content of a filler is 35-65 parts by weight. The invention further provides a preparation method of the gypsum-based self-leveling floor material. Self-leveling mortar prepared from the gypsum-based self-leveling floor material has the dual effects of high moisture absorption performance and humidity indication, and meanwhile various performance indexes of the self-leveling mortar are good.

Description

technical field [0001] This application relates to but not limited to the technical field of new building materials, especially to but not limited to self-leveling floor materials, specifically to but not limited to a moisture-sensitive gypsum-based self-leveling floor mortar and a preparation method thereof. Background technique [0002] Air relative humidity is one of the important environmental parameters closely related to people's life and production. If the indoor humidity is too low or too high, it will cause discomfort to the indoor personnel. The relative humidity of the air is an important parameter to measure the indoor environment, and it is of great significance to human health, indoor air quality and the storage of items. The national air quality standard stipulates the standard value of indoor relative humidity, which is 40% to 60% for air-conditioned rooms in summer and 30% to 60% for heated rooms in winter. Canadian scholar Anthony V. Arundel and others hav...
