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
The present invention relates to special cement base engineering materials, is a kind of cement-based self-leveling mortar with temp regulating function specifically.
Background technology
Ground radiation heating is emerging in recent years a kind of heating system, and it is imbedded in subsurface with thermal source, and the whole ground of even heating utilizes the accumulation of heat on ground self and the heat radiating rule that makes progress to conduct from the bottom to top, reaches the purpose of heating.So just overcome the deficiency of traditional heating system, can each room heated respectively and guaranteed the homogeneity of temperature in the room.
At present the ground radiation heating material that is used for filling zone of heating is generally pea gravel concreten and ordinary mortar, and following some is not enough and their exist:
(1) do not have temp regulating function, can only carry out the transmission of heat passively;
(2) mobile bad, in construction process, can there be uncompacted situation of filling;
(3) need 3 day time just can carry out follow-up work at least after the construction;
(4) filling the ground, back that finishes need carry out just carrying out the laying of ornament layers such as floor, carpet after the secondary levelling is handled.
Summary of the invention
The purpose of this invention is to provide a kind of cement-based self-leveling mortar with temp regulating function, the use of this material can make ground have temp regulating function, have the gentle fast hard characteristics of vibration-free self-flowing simultaneously, construct and to go up people walking in back 2 hours, and need not to handle can laying floor and carpet etc. on the surface.
A kind of cement-based self-leveling mortar of the present invention with temp regulating function, comprise following component and content by weight: 25～60 parts of cement, 50～80 parts in sand, 10～20 parts in flyash, 0.25～2.5 part of water reducer, 5～10 parts of swelling agents, 1～5 part of redispersable latex powder, 0.1～1.0 part of defoamer, 2～40 parts of phase change materials.Each component and preferred content can be 30～40 parts of cement, 50～60 parts in sand, 12～15 parts in flyash, 0.5～2.0 part of water reducer, 6～8 parts of swelling agents, 1～5 part of redispersable latex powder, 0.3～0.7 part of defoamer, 10～30 parts of phase change materials.
In the above-mentioned gravity flowing levelling mortar, described cement is that quick hardening sulphoaluminate cement, ordinary Portland cement or two kinds of cement are composite in all proportions; Described sand is artificial sand or natural sand, and particle diameter is 0.1mm～3mm; Described flyash is I level or II level ash; Described water reducer is poly carboxylic acid or naphthalenesulfonate condensation compound; Described swelling agent is calcium oxide or ettringite swelling agent; Described redispersable latex powder is that polymer emulsion spraying dryings such as VAE emulsion or ACRYLIC EMULSION form; Described defoamer is polyethers or silicone based defoamer; Described phase change material is paraffin, lipid acid and derivative thereof or normal alkane.
During making, by ratio requirement each component is dropped into stirrer, stirring gets final product.
During use, the material that the present invention is prepared adopts stirrer or manually mixes and stirs to become to have mobile gravity flowing levelling mortar according to the water of weight percent adding 18%～20%, evenly is poured on the ground.Because the material that mixes and stirs has extraordinary flowability, can obtain the very high ground of planeness so need not to vibrate.
The present invention adopts multiple high-quality raw material, and gravity flowing levelling mortar technology and phase change material heat preservation technology are fused to together, draws the rational proportion scope by a large amount of tests, makes a kind of special cement base engineering materials.This material can mix and stir into a kind of morning of strong gravity flow flat ground material after adding water at the construction field (site) fast.Beneficial effect of the present invention is: the material that mix and stir (1) has the gravity flow flat characteristic, can form the very high ground of surface finish, and the later stage need not to handle can carry out the laying of finishing material such as carpet, floor; (2) have early strong characteristics, construct and to go up people's walking in back 2 hours; (3) have temp regulating function, phase change material melts when envrionment temperature raises, and absorbs heat simultaneously, stops temperature to raise; Phase change material solidifies when envrionment temperature reduces, and emits heat simultaneously, stops temperature to reduce.The temperature weighing apparatus that can keep so within the specific limits in the room is fixed, reduces the duration of service of air-conditioning or heating installation, has saved the energy.
