The face work will not appear crack, knob and abscission. It can be constructed in lamina, thus it reduces the material and the waste, meanwhile, it improves the life of the building and saves the energy of about 60% compared to the conventional sand pulp and increases the working efficiency. The producing process and the using process is innocuous, flavourless, safe, healthful, easy to transport, waterproof, water conservation, not sagging and have the water as the solvent.
Description
Technical field
The invention belongs to the building adhesive field, relate in particular to a kind of outer wall heat preservation dry-powder mortar for construction that skin uses that is used for.
Background technology
The tradition mortar is with the mixture behind the uniform mixing such as the cement of dry powder, river sand, gelling material, chemical additive, stirs evenly the novel dry powder class mortar that can directly use as long as add water by a certain percentage during operation.Because this mortar feedstock property is single, in the setting and harden process, moisture evaporation forms more hole, the shrinkage of warming plates such as cement based hardenite and styrofoam differs greatly simultaneously, therefore be in the uneven higher stress that distributing at warming plate and the bonding interface of mortar, this stress is in thermodynamic (al) unsteady state, trend towards spontaneous uniform distribution, this acting under the extraneous effect, swollen, the phenomenon such as come off of wall crazing, sound water and coat of plaster sky often occurs, can't satisfy of the different requirements of modern New Building Materials mortar.
The tradition mortar is generally all mixed system at the construction field (site), mortar impervious poor, shrinking percentage is big, be whitewash cracking, flake, peel off, the weak link of construction quality problem generation such as seepage.Simultaneously, on-the-spot non-accurate metering preparation mortar inevitably causes the wasting of resources and environmental pollution.Along with the development of construction industry, the mortar of this on-the-spot preparation more and more is difficult to satisfy the requirement of modern mortar construction.In order to guarantee that construction engineering quality is controlled comprehensively, people begin to develop commercial dry-mix.Mix the mortar of system with respect to the traditional technology scene, dry-mix has quality product height, production efficiency height, environmental pollution and urinates in numerous advantages such as civilized constructions.The strong point of dry-mix is to have overcome the restriction that the premixing wet mortar must use up at the appointed time, and system can be mixed according to construction speed and demand scene in the building site, has avoided waste; Do not exist construction organization and feed to cooperate the contradiction of aspect between mortar manufacturer and the unit in charge of construction; The use of dry-mix need not special-purpose container; Owing to be that system is mixed at the scene, need not to consider the mortar flowability in time with the variation of weather.Dry-mix can be according to market requirement small serial production different varieties.Deficiency is that the most fatal shortcoming of dry-mix is that cost is higher.In the world at present these technological lines of dry-mix that adopt more.But the initial bonding force of existing dry-mix is relatively poor, needs smearing of big thickness, and the large usage quantity that this can cause mortar has increased buildings and construction cost.
Summary of the invention
It is good to the purpose of this invention is to provide a kind of splitting resistance, the outer wall heat preservation dry-powder mortar for construction of wiping one's face flawless, hollowing and coming off, this dry-mix are solvent with water, thin layer construction, the few loss of materials is low, has solved the defective that existing dry-mix and traditional mortar exist.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of outer wall heat preservation dry-powder mortar for construction is characterized in that it is formulated by following materials of weight proportions:
Cement 500～700
Water-ground limestone 200～300
Grey matter lime carbonate 100～200
Re-dispersible glue powder 15～25
Vltra tears 2～4
Lignocellulose 0.5～1.5
Polypropylene fibre 0.5～1.5
Described cement is selected from each trade mark ordinary Portland cement and high-alumina cement for building.
Described water-ground limestone is fineness 800～3000 purpose water-ground limestones or nano level water-ground limestone.
The described rubber powder that disperses is ethene-vinyl acetate co-polymer class, polyvinyl alcohol, polyethylene kind, methylcellulose gum or polyacrylamide, and their binary or terpolymer are that the commercially available building water of main component can disperse rubber powder.
Described Vltra tears can use hydroxyethylmethyl-cellulose, hydroxypropyl carboxy methyl Mierocrystalline cellulose or Hydroxypropyl ethyl cellulose to replace.
This outer wall heat preservation dry-powder mortar for construction is formulated by following concrete materials of weight proportions:
Cement 600
Water-ground limestone 250
Grey matter lime carbonate 150
Re-dispersible glue powder 20
Vltra tears 3
Lignocellulose 1
Polypropylene fibre 1
The production method of this outer wall heat preservation dry-powder mortar for construction is fairly simple, gets final product after various raw materials are mixed by weight ratio, and required various raw materials are the commercial goods.Its central gray lime carbonate claims grey calcium powder again, the OK powder, and it is to adopt natural black limestone resource, by the meal that selects stone, high-temperature calcination, chemical formulation, apparatus processing to form, mainly is applicable to the production of environment-friendly type emulsion paint, porcelain-imitated coating, water-proof putty.Re-dispersible glue powder is commercially available water-dispersion dry glue powder for building, is a kind of by the powder adhesive of making after the emulsion polymerization spraying drying.This powder with can form emulsion by very fast redispersion after water contacts, and have the character identical with initial latex, promptly can form film after the water evaporates, this film has high-flexibility, high weather resisteant and to the high-adhesion of various base materials.It can improve the performance of mortar, improves the intensity of mortar, improves the bonding strength of mortar and various base materials, improves flexibility and deformability, ultimate compression strength, folding strength, wearability, toughness and the bonding force of mortar.Polypropylene fibre is the pencil monofilament of polypropylene material, and it can effectively disperse the string stress of mortar in drying process, eliminates the cracking problem.
Beneficial effect of the present invention is that this outer wall heat preservation dry-powder mortar for construction adopts the combination of cementaceous binding agent and polymeric binder, makes its product that satisfies high request as the building industry preparation become possibility.Its splitting resistance is good, has excellent elasticity and snappiness, and wiping one's face crackle can not occur, hollowing and come off long service life.Can carry out thin layer construction, the few loss of materials is low, improves the work-ing life of building simultaneously, and comparable traditional mortar is energy-conservation about 60%, has also improved working efficiency.Production process and use simultaneously is nonpoisonous and tasteless, not discharging, and the construction safety health is convenient to transportation, is solvent with water, and the scene adds water stirs and promptly can use, and workability is good, water-fast, water conservation, sagging not, does not pollute.
