Conductive heating mortar with thermal insulation capability and preparation method thereof
The invention discloses conductive heating mortar with thermal insulation capacity. The conductive heating mortar is prepared from the following components in parts by weight: 400 to 500 parts of cement, 1300 to 1400 parts of standard sand, 200 to 250 parts of water, 0.7 to 1.2 parts of a water reducing agent, 0.4 to 5 parts of graphene and 4 to 50 parts of phase change microcapsules, compared with the prior art, when the graphene is used as a conductive material of the conductive heating cement mortar, not only is the conductivity given to the cement mortar, but also the strength of the cement mortar can be improved. When the phase change microcapsule is used as a thermal insulation material of the conductive heating cement mortar, although the phase change microcapsule can preserve heat and store heat, the strength of the cement mortar is reduced. At the moment, the advantage that the graphene serves as a conductive material is achieved, the improvement of the strength of the graphene and the reduction of the strength caused by the phase-change microcapsules complement each other, and the graphene can also serve as a heat conduction material to transfer heat in the cement mortar.
本发明公开了一种具有保温能力的导电发热砂浆，按照重量份数计算包括以下各组分：水泥400‑500份、标准砂1300‑1400份、水200‑250份、减水剂0.7份‑1.2份、石墨烯0.4份‑5份、相变微胶囊4份‑50份；本发明与现有技术相比，当石墨烯作为导电发热水泥砂浆的导电材料时，不仅赋予了水泥砂浆的导电性，还可以提升水泥水泥砂浆的强度。而当相变微胶囊作为导电发热水泥砂浆的保温材料时，虽然能保温并储存热量，但会造成水泥砂浆的强度下降。这个时候石墨烯充当导电材料的好处就提现出来了，其强度的提升与相变微胶囊造成的强度下降，两者互补，相辅相成，并且石墨烯还可以作为导热材料在水泥砂浆内进行传热。
