Abstract
A leveling mortar powder containing paraffin wax for accumulating heat is prepared from cement, aggregate, fibres and paraffin wax through fusing paraffin wax or preparing 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 building mortar and preparation method thereof.
Background technology
Existing building mortar generally comprises cement, aggregate 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 paraffin accumulation of heat leveling mortar powder and paraffin accumulation of heat leveling mortar, solution existed building leveling mortar water-intake rate is big, water-repellancy is poor, coefficient of softening is low, not water-proof technical problem.
The technical scheme of paraffin accumulation of heat leveling mortar powder of the present invention: it comprises 30～65% cement, 20～40% aggregate and 0.5～10% fiber, it is characterized in that: also contain 5～30% 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 0～45% in the above-mentioned cement.
Contain the flyash of cement total amount 0～45% and 0～5% slaked lime in the above-mentioned cement.
The silica flour that contains cement total amount 0～5% in the above-mentioned cement.
Above-mentioned aggregate is the mixture of sand, pearlstone, expanded vermiculite, haydite, rubber grain or above-mentioned aggregate.
Above-mentioned aggregate is the mixture of pearlstone and expanded vermiculite, and optimum weight ratio is an expanded vermiculite: pearlstone=2.
Above-mentioned fiber is inorganic fibre, organic fibre or the blend fiber of the two.
The preparation method of this paraffin accumulation of heat leveling 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 and aggregate then mixes and stirs and promptly make paraffin accumulation of heat leveling mortar powder;
When (3) using, need only and stir into paste toward above-mentioned paraffin accumulation of heat leveling mortar powder adding suitable quantity of water and be paraffin accumulation of heat leveling 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 building mortar owing to added paraffin, and the water-absorbent of building mortar has also obtained better controlled.Simultaneously because the solid-liquid conversion of paraffin under 20～50 ℃ of conditions; exist decalescence and exothermic process; 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 building mortar by the heat of phase transformation of paraffin, thereby make building 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 building mortar during liquefaction, thereby this paraffin accumulation of heat leveling mortar also has automatic healing anti-cracking function, makes the anti crack performance of building mortar obtain further raising.The heat-insulating property of this paraffin accumulation of heat leveling 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 leveling mortar water-intake rate is big, water-repellancy is poor, coefficient of softening is low, not water-proof technical problem, and the levelling that can be used for the various thermal insulation layer surface layers of body of wall and roofing is handled.Solid-liquid phase change takes place and transforms in contained paraffin under 20～50 ℃ of conditions, exist heat absorption and exothermic process, can play good accumulation of heat effect, thereby improve indoor thermal environment.
