Abstract
The invention belongs to a technical field of building materials, providing self-leveling elastic mortar. The component and weight percentage of the self-leveling elastic mortar are that cement takes 10-35%, quartz sand takes 30-70%, admixture takes 0-10%, polymer emulsion takes 5-25%, water reducing agent takes 0.1-2%, defoamer takes 0.1-1.5% and water takes 0-20%. The film of the mortar of the invention is provided with elasticity and strength, simultaneously, the self-leveling of the mortar is good, which satisfies construction requirements.
Description
Technical field
The present invention relates to mortar for building, relate in particular to a kind of self-levelling elastic mortar.
Background technology
Through the development of many decades, terrace has become quite sophisticated industry in developed country.It is covering extensive fields, comprises several hundreds of products of big series such as epoxy, chlorinatedpolyolefins, urethane, polyureas, integrates protection, decoration, function.Sports buildings, the lounge of the range of application of terrace from universal industrial premises, corridor, parking lot, market to high-decoration, and even special-purpose terrace such as high performance conduction, sparkproof, chemicals-resistant etc., and application surface constantly enlarges.Since reform and opening-up, the construction of large quantities of development areas and industrial premises has spurred the development of terrace industry.Along with domestic specialized terrace company progresses into fast developing lane, terrace becomes one of field with fastest developing speed of coating industry in recent years, to the end of the year 2004 its output value above 15 hundred million.
In many application scenarios of terrace, some elasticity to terrace has requirement to a certain degree.As the physical culture room, the sportsmen at the volley, the situation of falling often arranged, rolling occurs, for the protection sportsmen avoids injury, earth material should be too not hard, and suitable buffering should be arranged; In addition, often will do various spring-like movement in the motion, ground is elasticity slightly, helps the performance of sportsmen's level, protection pin joint.Playing field, children ' s activity place, part dance hall etc. require ground to have certain elasticity equally.Locate in office, hospital etc., the use of terrace is people's walking substantially or stands, therefore also the elasticity of terrace is had to a certain degree requirement.
Terrace is made up of priming paint, mortar, finish paint usually, and in order to guarantee the elasticity of whole terrace, screed and surface layer all need to possess certain elasticity.Screed is the thickest layer during terrace constitutes, and its planarization is most important to the planarization of whole terrace.Therefore in the screed construction process, need carry out levelling, use mechanical means to make it smooth usually,, operating efficiency will be improved a lot if mortar has certain self-leveling.But in the existing mortar process for preparation, elasticity and self-leveling normally can not get both, and do not have all excellent mortar product of elasticity and self-leveling on the market.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the mortar that provides a kind of elasticity, intensity and levelling property to have concurrently.
The technical scheme of technical solution problem of the present invention is:
A kind of self-levelling elastic mortar is characterized in that each component and quality percentage composition are:
Cement 10～35%
Quartz sand 30～70%
Adulterant 0～10%
Polymer emulsion 5～25%
Water reducer 0.1～2%
Defoamer 0.1～1.5%
Water 0～20%
In a kind of preferred scheme, each component and quality percentage composition are:
Cement 20～35%
Quartz sand 35～60%
Adulterant 3～6%
Polymer emulsion 10～20%
Water reducer 0.5～1%
Defoamer 0.5～1%
Water 8～15%
Described cement can be selected ordinary Portland cement or portland cement or high-alumina cement for use.
It is 60～200 purpose quartz sands that described quartz sand can be selected granularity for use.
Described adulterant can be selected the mixture of flyash or dry powder or both arbitrary proportions for use.
Described polymer emulsion is selected from the emulsion of the polymkeric substance that contains acrylic, vinyl, styryl, epoxy group(ing), methylene radical, ester group, ether, urethano or urea groups, the polymer emulsion that preferred alkenes, vinylformic acid, methacrylic acid, acrylate, methacrylic ester form through homopolymerization or copolymerization, more preferably butadiene-styrene copolymer emulsion or latex of copolymer in cinnamic acrylic ester.
Described water reducer can be selected for use and be naphthalene system or polycarboxylate based water reducer.
Described defoamer can be selected mineral oils or silicone based or polyethers defoamer for use.
Mortar of the present invention can be prepared according to the method for routine, cement, sand and adulterant is mixed make solid components, polymer emulsion, water reducer, defoamer, water is mixed make liquid phase component.Solid components is joined among the liquid phase component, stir 2～3min with medium rotating speed and get product.
Compare with conventional cement mortar, the present invention has used polymer emulsion, and the folding strength of mortar is significantly improved, and has possessed certain elasticity.Simultaneously, because the application of water reducer and the adjustment of the water yield make the self-leveling of mortar can satisfy the construction needs.The difference of the present invention and existing mortar product is to have concurrently elasticity and self-leveling.
