Abstract
A mortar powder containing paraffin wax for phase-change insulating is prepared from cement, light aggregate, fibres and paraffin wax through fusing paraffin wax or preparing the microcrystal powder of paraffin wax, and proportionally mixing it with others. Its advantages are low hydroscopicity and high water-proof performance and softening coefficient.
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 0~40% in the above-mentioned cement.
The flyash, 0~25% slaked lime and 0~5% the gypsum that contain cement total amount 0~40% in the above-mentioned cement.
The silica flour that contains cement total amount 0~5% in the above-mentioned cement.
Above-mentioned light skeletal is a granular polystyrene.
Above-mentioned light skeletal is granular polystyrene, pearlstone, expanded vermiculite, haydite, a kind of light skeletal particle of rubber grain or above-mentioned two or more light skeletal particulate mixture.
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 generally 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;
When (3) using, above-mentioned wax size powder added stir into pasty state in the entry, add 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.
