Description
Technical field
The present invention relates to the mortar composite modifier of widespread use in a kind of construction work, relate to all kinds of mortars in the present construction work concretely, as the aggregate of chemical admixture, mineral additive, fiber or the pigment etc. of usefulness such as preparation masonry mortar, plastering mortar, ground mortar, waterproof mortar.
Background technology
Current Chinese architecture is just in the ascendant, and building construction increases year by year, reaches 500,000,000 square metres in 2003, mainly is public building, factory building and dwelling construction, and the ratio maximum that dwelling house accounts for.Shanghai only, 1,600 ten thousand square metres in annual newly-built dwelling house, expection in 2003 surpasses 2,000 ten thousand square metres, and old house is transformed about 200,000,000 square metres.Therefore, the required gelling material enormous amount of building construction, but the gelling material of using on the engineering remains traditional material at present, can't improve construction quality, therefore China's building construction quality still seriously exist splitting of just obviously seeing in appearance, take off, distension, leak, ooze, surface phenomena such as mould, see through this surface phenomena, can cause buildings function reduction or interior of building impaired, comprise the whole more serious adverse consequences of damaging.
The reconstruction or the repairing that are caused by these two kinds of reasons (buildings function reduction or impaired) must consume the material of construction that this should not consume, directly waste energy and resource, be unfavorable for very much Sustainable development, therefore, should particularly novel building mortar and corresponding new technology be avoided this phenomenon by using novel material.
The application scenario of building mortar is a lot, except that should having sufficiently high mechanical property, also should have effects such as protection body of wall, decoration, insulation, heat insulation, waterproof and anti-contamination; in addition, require its workability good, water-retentivity is suitable; easy construction, the work efficiency height, easy to maintenance.In mechanical property, the most important thing is cohesive strength, particularly stand temperature variation after cohesive strength should not reduce, therefore this is that the traditional architecture mortar is not accomplished, must thoroughly carry out modification to it, gives its enough function.And crucial material modifiedly forms, and according to use occasion and requirement and reasonable composition by the number of chemical admixture.Though the consumption of these chemical admixtures is very little, effect significantly has very big influence to the performance of building mortar.Can be suitable for different geographical conditions, level and orientation, even its inside and outside each layer of material that also is suitable for same position has multiple function to shearing resistance, antidetonation, protection against the tide, waterproof, insulation and heat insulation different requirements.
The kind of admixture is a lot, and its performance is closely related with volume again, improper or excessive too small quality or the adverse consequences economically of all can causing of volume of proportioning.And the construction site lacks the professional, can not prepare these chemical admixtures in the building site.This only just can be achieved in factory.Therefore, be necessary the chemical admixture of extraordinary mortar and dedicated mortar is prepared in factory, make mortar partner, and, solve the key technical problem of mortar preparation directly to the working-yard supply of material.
Summary of the invention
One of purpose of the present invention is exactly at the problems referred to above, and provide a kind of and can be applied to multiple material, and the convenient mortar partner that uses.
Another object of the present invention provides the purposes of above-mentioned this mortar partner.
To achieve these goals, technical scheme of the present invention is:
A kind of mortar partner, the mass fraction of each component is as follows:
Limestone powder 50-85
Latex powder 8-30
Ether of cellulose 0.5-14
Air entrapment agent 0-0.3
Starch ethers 0-0.2
Hydrophober 0-5
Mineral dye 0-3
Organic fibre 0-18.
Mortar partner of the present invention, wherein the limestone powder fineness is preferably in 100 orders or following.
Mortar partner of the present invention, wherein latex powder can be an ethene-vinyl acetate emulsion copolymer powder, also can be acrylic acid or the like latex powder etc.
Mortar partner of the present invention, wherein ether of cellulose can be the product of technical grade, and its viscosity is between 100-60000Pas.
Mortar partner of the present invention, owing to be the dry mortar companion of premix, air entrapment agent, starch ethers and hydrophober all should be dry powder, and commercially available gets final product, and its concrete model, brand etc. are unrestricted.
Mortar partner of the present invention, wherein pigment should be inorganic oxide pigments, and as ferric oxide, chromic oxide etc., therefore the performance that how much can not influence mortar partner of its consumption also can add according to practical situation and needs when concrete application.
Mortar partner of the present invention, wherein organic fibre can be polypropylene fibre, polyacrylamide fiber, also can be nylon-6 fiber, filament length is 12mm ± 3mm; Can be the assorted fibre of different filament lengths, but filament length should not surpass 15mm yet.
The preparation method of mortar partner of the present invention is: by the good each component of above-mentioned weight proportion weighing, stir, mix and get final product.When on the construction site, using, as long as mortar partner of the present invention and cement, aggregate and water are mixed and stirred, with regard to all kinds of building mortars of availability excellence.
Mortar partner of the present invention comprises all the mortar compositions except cement, sand and water, can directly stir into mortar with cement, Sha Heshui on the construction site and use, and also can be used as the starting material of dry-mix factory.
Mortar partner of the present invention has the protection body of wall, and effect such as decoration, insulation, heat insulation, waterproof, sound-absorbing, anti-contamination, anti-chemical corrosion and radioprotective is applicable to matrix material, finishing material, lagging material and water-proof material.
Mortar partner of the present invention, it is high effective and modified dose powder aggregate, with gelling material with after mixing water contacts, have excellent dispersiveness and suitable solvability, to the workability, water-retentivity and the cohesive force that solve gelling material and with the coupling of base material the excellent effect of improving is arranged.
Because different basic unit's material is different to the requirement of the kind of various properties-correcting agent and volume, mortar partner of the present invention can be according to different basic unit's materials (chemical constitution, state of aggregation, condition of surface, water-absorbent, intensity of variation expands with heat and contract with cold), concrete proportioning to each component is selected, and makes the mortar partner that is complementary.When it varies with temperature and the expansion and contraction of base material adapt, make cohesive strength not change its use properties with variation of ambient temperature.
Mortar partner of the present invention has solved the intensity and the heat-insulating property of material, and impervious and gas-pervious antagonism reaches rational performance combination.
Beneficial effect of the present invention:
1. adopt the mortar partner of the present invention's preparation to have the protection body of wall, difference in functionalitys such as decoration, insulation, heat insulation, waterproof and anti-contamination.
2. mortar partner of the present invention is applicable to that multiple weather condition use.
3. mortar partner of the present invention is widely used in preparing building mortars such as matrix material, finishing material, lagging material and water-proof material.
4. mortar partner of the present invention has higher adaptability to different substrate materials, as polystyrene foam plate, normal concrete metope, gas concrete and mixed structure thereof etc.
