Description
Technical field
The present invention relates to article conventional in a kind of construction and preparation method thereof, more particularly, it relates to a kind of polymkeric substance mending mortar and preparation method thereof.
Background technology
Polymkeric substance mending mortar, be the high-strength inorganic tackiness agent should not developed specially as lagging material protective layer for conventional cement mortar, alternative all kinds of Organic adhesive, increases substantially the quality of heat-insulation system.
Polymkeric substance mending mortar is a kind of cementability both with macromolecular material, has again the new concrete mending mortar of inorganic materials weather resistance; Ultimate compression strength is high, and rapidly, adhesiveproperties is good in solidification; There are good water retention property and splitting resistance, high alkali resistance, UV resistant; Easy and simple to handle, can construct by wet base, health environment-friendly.Construction procedure is become simply, conveniently, weather resistance and concrete synchronous, the reduction of erection time, can guarantee economy.And more existing polymkeric substance mending mortars, inconvenient when in use, and due to system component, having used of a specified duration can ftracture, and causes detrimentally affect.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of long perfomance life, indehiscent polymkeric substance mending mortar and preparation method thereof.
For achieving the above object, the invention provides following technical scheme: a kind of polymkeric substance mending mortar, its feed composition and component as follows:
Cement: 400 parts-500 parts
Quartz sand: 500 parts-600 parts
High molecular polymer: 1 part-5 parts
Polymkeric substance: 5 parts-15 parts
SILICA FUME: 1 part-5 parts
Wood fibre: 0.1 part-0.3 part
Wherein said high molecular polymer is ether of cellulose, and described polymkeric substance is redispersable latex powder.
The present invention is set to further: described cement is conch 42.5 ordinary Portland cement.
The present invention is set to further: described ether of cellulose is 2 parts.
The present invention is set to further: described redispersable latex powder is 10 parts.
Present invention also offers a kind of preparation method of this polymkeric substance mending mortar: by proportioning number by cement, quartz sand, high molecular polymer and polymkeric substance, pour in stirrer and stir, obtain polymkeric substance mending mortar.
By adopting technique scheme, based on cement, quartz sand, ether of cellulose and redispersable latex powder are auxiliary, are composited.Mierocrystalline cellulose is a kind of poly-hydroxy macromolecular compound neither dissolving also not melting.Mierocrystalline cellulose then can water-soluble, dilute alkaline soln and organic solvent after etherificate, and has thermoplasticity.Cellulose dissolution performance generation noticeable change after etherificate, is dissolvable in water water, diluted acid, diluted alkaline or organic solvent, and has thermoplasticity.Redispersable latex powder product is water-soluble redispersible powder; be divided into the multipolymer of ethylene/vinyl acetate, vinyl acetate between to for plastic/tertiary monocarboxylic acid ethylene copolymer, acrylic copolymer etc.; the powder adhesive made after spraying dry, using polyvinyl alcohol as protective colloid.This powder can become emulsion by very fast redispersion after contact with water, because redispersable latex powder has high viscosifying power and unique performance, as: water resisting property, application property and thermal insulation etc.SILICA FUME is also silicon ash or is claimed cohesion silicon ash, can the intergranular hole of filling concrete, generates gelinite simultaneously, react generate gelinite with basic material magnesium oxide with hydrated product.In the concrete of cement based, mortar and refractory material casting material, mix appropriate silicon ash, can function as follows: 1, significantly improve resistance to compression, anti-folding, impervious, anticorrosion, shock resistance and wear resisting property.2, have water conservation, prevent segregation, bleeding, significantly reduce the effect of concrete pumping resistance.3, the work-ing life of significant prolongation concrete.Particularly under the severe environment such as villiaumite system erosion, sulphate attack, high humidity, the weather resistance of concrete can be made to double even several times.4, significantly reduce the ash that lands of jetting cement and mould material, improve single jetting thickness.5, be the necessary composition of High Strength Concrete, the engineer applied of existing C150 concrete.6, there is effect of about 5 times of cement, apply in ordinary concrete and Low Cement Castable and can reduce costs. improve weather resistance.7, concrete alkali-aggregate reaction is effectively prevented.8, the compactness of casting type refractory materials is improved.With Al2O3 and when depositing, more easily generate mullite phase, make its hot strength, shaking property of heat resistanceheat resistant strengthens.9, there is extremely strong volcano ash effect, during mixed concrete, with hydrolysis product of cement Ca (OH) 2, secondary reaction of hydration can occur, form gelled product, filling concrete stone structure, improves the microtexture of slurry, improves mechanical property and the weather resistance of hardenite.10, SILICA FUME is unformed spherical particle, can improve concrete rheological property.11, the average particle size particle size of SILICA FUME is smaller, has good filling effect, can be filled between cement granules space, improves concrete strength and weather resistance.Wood fibre is that natural reproducible timber processes through chemical treatment, mechanical process the organic wadding fibrous material obtained.Good effect is had to preventing coating cracking, raising water-retentivity, the stability improving production and the conformance of construction, the sticking power etc. of effects on surface of gaining in strength, strengthen.Its technical role is mainly: thixotroping, protection, absorption, carrier and weighting agent.The common sand-cement slurry of the bonding of this product, cracking resistance, distortion, the Performance Ratio such as freeze proof, corrosion-resistant, wear-resisting improves a lot, the defect mendings such as the hole of different strength concrete, honeycomb, pitted skin can be adapted to, the repair layer that weather resistance is good can be formed.Have good construction workability energy, without the need to vibrating during construction, the stirring that adds water at the scene can use; Early strong, high-strength, within 3 days, ultimate compression strength can reach 200MPa, can speed up the work to greatest extent; Adhesive property is good, is greater than 2.5MPa with the cohesive strength of New-old concrete, at utmost can ensure strong concrete mending mortar and repair closely bonding between basic unit; Can winter construction, when polymkeric substance mending mortar allows envrionment temperature more than-5 DEG C, carry out the repairing outdoor construction of the keeping up appearances of concrete structure, horizontal plane and end face; Weather resistance is strong, and after 50 freeze-thaw cycle, intensity is without considerable change, soaks intensity after 30 days and improves, be applicable to various engineering in machine oil.
