Example Embodiment

[0015] Example 1

[0016] Choose 60kg of cement, 80kg of sand, 20kg of fly ash, 2.5kg of water reducing agent, 10kg of expansion agent, 5kg of redispersible latex powder, 1kg of defoamer and 40kg of phase change material. First, put the sand and cement into the mixer for mixing, then put the water reducing agent, fly ash, expansion agent, redispersible latex powder, defoamer, and phase change material into the mixer, mix them evenly, and pack them into bags.

Example Embodiment

[0017] Example 2

[0018] Select 25kg of cement, 50kg of sand, 10kg of fly ash, 0.25kg of water reducing agent, 5kg of expansion agent, 1kg of redispersible latex powder, 0.1kg of defoamer and 2kg of phase change material. First put the sand and cement into the mixer for mixing, then put the water reducing agent, fly ash, expansion agent, redispersible latex powder, defoamer, and phase change material into the mixer, and mix all the selected materials evenly in the factory Packed into bags. After transporting to the construction site, add 20% water according to the weight of the material, stir it with a hand electric drill for 2 minutes to form a self-leveling early-strength ground material with good fluidity, and then evenly pour it on the ground radiant heating equipment to form a dense and flat filling Floor.

Example Embodiment

[0019] Example 3

[0020] Select 35kg of cement, 55kg of sand, 13kg of fly ash, 1.5kg of water reducing agent, 7kg of expansion agent, 2kg of redispersible latex powder, 0.5kg of defoamer and 20kg of phase change material. After processing according to the method of Example 2, it was packaged into bags. After transporting to the construction site, add 20% water according to the weight of the material, stir it with a forced mixer, a hand drill or manual stirring to form a self-leveling and early strength ground material with good fluidity, and then pour it evenly on the ground radiant heating equipment. A dense and flat filling layer is formed. When the ambient temperature is 20°C, you can enter the building within 2 hours after construction.

Abstract

The invention proposes a cement based self-leveling mortar with a temperature regulation function, which comprises the following components according to parts by weight: 25 portions to 60 portions of cement, 50 portions to 80 portions of sand, 10 portions to 20 portions of fly ash, 0.25 portion to 2.5 portions of water reducing agent, 5 portions to 10 portions of expansion agent, 1 portion to 5 portions of redispersible latex powder, 0.1 portion to 1 portion of defoaming agent and 2 portions to 40 portions of phase change material. The invention has the advantages: (1) well mixed material has a self-leveling feature and can form ground with very high surface evenness; (2) the mortar has a high-early strength feature and people can walk on the surface 2 hours after the application of the mortar; and (3) the mortar has the temperature regulation function. The phase change material melts and absorbs heat to prevent temperature from rising when the ambient temperature rises; the phase change material solidifies and gives out heat to prevent temperature from reducing when the ambient temperature reduces, therefore, the temperature in a room can be maintained constant within a certain range to reduce the use time of an air conditioner or a central heating, thereby saving energy.

Description

technical field [0001] The invention relates to special cement-based engineering materials, in particular to a cement-based self-leveling mortar with a temperature adjustment function. Background technique [0002] Ground radiant heating is an emerging heating method in recent years. It buries the heat source under the ground, uniformly heats the entire ground, and uses the ground's own heat storage and upward heat radiation to conduct conduction from bottom to top to achieve the purpose of heating. In this way, the deficiency of the traditional heating method is overcome, and each room can be heated separately and the uniformity of the temperature in the room is ensured. [0003] At present, the materials used to fill the heating layer for ground radiant heating are generally fine stone concrete and ordinary mortar, but they have the following shortcomings: [0004] (1) There is no temperature adjustment function, and heat transfer can only be carried out passively; [00...
