Abstract
The present invention relates to paraffin phase-changed thermal-insulating mortar powder and a preparing method thereof. The paraffin phase-changed thermal-insulating mortar powder comprises 35% to 75% of cement, 5% to 40% of light aggregate and 0.5% to 10% of fibers and also contains 5% to 40% of paraffin, and partial cement can be replaced by pulverized coal ash, slaked lime, gypsum or silicon powder. When the paraffin phase-changed thermal-insulating mortar powder is prepared, the paraffin is firstly heated and melted and is sufficiently stirred to be uniformly dispersed, or the paraffin is prepared into microcrystal powder; the melted and dispersed paraffin or paraffin microcrystal powder and other materials are uniformly mixed to be made into paraffin glue powder which is then added in water to be stirred into paste, and then the light aggregate are added in the paste to be sufficiently stirred. The paraffin phase-changed thermal-insulating mortar powder solves the technical problems of large water absorption, poor waterproofing performance, low softening coefficient and no water resistance existing in the existing thermal-insulating mortar, and can be used for various thermal-insulating layers of walls and roofing.
Description
Technical field
The present invention relates to a kind of thermal insulation mortar and preparation method thereof.
Background technology
Existing thermal insulation mortar generally contains cement, light skeletal and fiber, exists defectives such as water-intake rate is big, water-repellancy is poor, coefficient of softening is low, not water-fast, thereby is subjected to weather effect bigger during construction.
Summary of the invention
The invention provides the preparation method of a kind of wax phase change thermal insulation mortar powder and wax phase change thermal insulation mortar, the existing thermal insulation mortar water-intake rate of solution is big, water-repellancy is poor, coefficient of softening is low, not water-proof technical problem.
The technical scheme of wax phase change thermal insulation mortar powder of the present invention: it comprises 35～75% cement, 5～40% light skeletal and 0.5～10% fiber, it is characterized in that: also contain 5～40% paraffin in proportioning.
Above-mentioned paraffin is the mixture of native paraffin, synthetic paraffin or native paraffin and synthetic paraffin.
The flyash that contains cement total amount 5～40% in the above-mentioned cement.
The flyash, 2～25% slaked lime and 1～5% the gypsum that contain cement total amount 5～40% in the above-mentioned cement.
The silica flour that contains cement total amount 1～5% in the above-mentioned cement.
Above-mentioned light skeletal is a granular polystyrene.
Above-mentioned light skeletal is a kind of light skeletal particle or an above-mentioned two or more light skeletal particulate mixture in granular polystyrene, pearlstone, expanded vermiculite, haydite, the rubber grain.
Above-mentioned fiber is inorganic fibre or organic fibre, or the blend fiber of said two devices.
The preparation method of this wax phase change thermal insulation mortar is characterized in that comprising the following steps:
(1) earlier with extremely fusing of heating paraffin, be 80～100 ℃, and fully stirring is uniformly dispersed it, or paraffin is prepared into microcrystal powder;
(2) will melt scattered paraffin or paraffin microcrystal powder and cement, fiber, admixture then packs into to mix in the mixing machine and makes the wax size powder; This powder comprises 35～75% cement, 0.5～10% fiber and 5～40% paraffin;
When (3) using, above-mentioned wax size powder added stir into pasty state in the entry, add 5～40% light skeletal again and fully stir into paste, be the wax phase change thermal insulation mortar.
Above-mentioned admixture is one or more the mixture in hardening accelerator, whipping agent, thixotropic agent, hydrophober, frostproofer, diffusant, water reducer, the water-holding agent.
Beneficial effect: the present invention has improved workability, water resistance, water resistance and the coefficient of softening of thermal insulation mortar owing to added paraffin, and the water-absorbent of thermal insulation mortar has also obtained better controlled.When envrionment temperature raises; paraffin liquefaction heat absorption; thereby the temperature of institute's object of protection can significantly not raise because of the rising of envrionment temperature; when envrionment temperature reduces; the paraffin curing exotherm; thereby the temperature of institute's object of protection can obviously not reduced because of the reduction of envrionment temperature, that is to say the heat storage capacity that has improved thermal insulation mortar by the heat of phase transformation of paraffin, thereby make thermal insulation mortar have good heat-proof quality.In addition, because the solid-liquid phase change of paraffin, the crack that may exist in can the filling thermal insulation mortar during liquefaction, thereby this paraffin thermal insulation mortar also has automatic healing anti-cracking function, makes the anti crack performance of thermal insulation mortar obtain further raising.The heat-insulating property of this paraffin thermal insulation mortar mainly realizes that by the light skeletal that adds low thermal conductivity the lightweight siliceous raw material of Jia Ruing also has certain contribution to heat-insulating property simultaneously.The present invention solves that existed building thermal insulation mortar water-intake rate is big, water-repellancy is poor, coefficient of softening is low, not water-proof technical problem, can be used for the various thermal insulation layers of body of wall and roofing.Solid-liquid phase change takes place and transforms in contained paraffin under 20 ℃～50 ℃ conditions, exist heat absorption and exothermic process, can play good accumulation of heat effect, thereby improve indoor thermal environment.The present invention has the heat insulating double effects, and the lower light skeletal of thermal conductivity that insulation effect is mainly passed through to be added realizes, heat-blocking action mainly by adding paraffin phase-transition heat-storage be used for realizing.
