The invention relates to recycled aggregate surface mortar for a thermal insulating block wall. The recycled aggregate surface mortar is prepared from the following components in parts by weight: 25-35 parts of cement, 15-20 parts of coal ash, 22-32 parts of aggregate, 10-20 parts of a thermal insulation material, 8-16 parts of a packing material, 1-3 parts of redispersible emulsion powder, 0.5-1.0 parts of anti-crack fiber, and 1-3 parts of an additive. The surface mortar disclosed by the invention is good in workability, high in bonding strength, good in thermal performance, and more suitable for the building external wall insulation system from the durability, fireproof performance and environment-protecting aspects; the coating mortar can be matched with the wall material to solve the problems of energy loss and cracking of the existing concrete block wall due to cold bridge and moisture condensation.
Description
Technical field
The present invention relates to building energy conservation environment-friendly materials field, particularly relate to a kind of external wall regeneration aggregate plastering mortar of thermal insulation system.
Background technology
2014 firmly the portion of building issue GB/T 50378-2014 " green building assessment standard " revised edition; require in the life cycle management of building; can economize on resources to greatest extent (energy-conservation, save land, economize on water, material-saving), protection of the environment and decreasing pollution; for people provide healthy, are suitable for and efficient usage space, with natural harmony symbiosis.And 2014 rise, the guarantee house of all municipalities directly under the Central Government, municipalities and cities with independent plans and provincial capital's construction will all implement green building standard.And energy-conservation, material-saving and material resources to utilize be all the main consideration item evaluating green building grade.
The power loss of buildings exterior-protected structure mainly comes from the aspects such as exterior wall, door and window and roofing, and therefore the heat preservation technology of roofing and exterior wall is the important channel and the necessary technology means that realize building energy conservation.Adopt the fine aggregate after light heat insulation material and discarded concrete crushing and screening for gathering materials, the activated waste material of industrial tool and replacing partial cement are mixed with and self have insulated fire function concurrently and the sharp useless exterior wall plastering mortar of energy, have good social effect and wide market outlook.
Traditional plastering mortar mainly for thermal insulation molded polystyrene foams plastics in building heat preservation system and extrusion molding polystyrene polyfoam for heat insulation two class heat insulating products surface and make.Two class insulation layer surface are all flexible body, and traditional plastering mortar and its formation flexible body-stiffener and organic and inorganic interfacial layer, be present in certain drawback, bond firm not and fire resistance is poor.When the self heat insulation wall that traditional plastering mortar is built by laying bricks or stones for insulation blocks, there will be and shrink greatly, and insulation blocks differs larger with the thermal conductivity of traditional plastering mortar, body of wall can be caused to occur " heat bridge " or " cold bridge " phenomenon, cause the immediate loss of wall thermal insulating energy, affect integral heat insulation effect.Develop thus and meet relevant mechanics and weather resistance aspect performance requriements, meet again low thermal conductivity requirement, and effectively make use of building waste, industrial waste, and extremely important with the matching used plastering mortar of insulation blocks body of wall.
Summary of the invention
In recent years, lack of energy and problem of environmental pollution are more and more serious, and exploitation renewable energy source improves the important topic that energy use efficiency becomes facing mankind simultaneously, and the present invention utilizes regeneration aggregate to replace natural sand, make use of industrial waste as a part of gelling material simultaneously, add suitable lagging material, consider grating, by rational proportioning, there is provided a kind of thermal and insulating performance good, fire prevention, good endurance, not only useless the but also a kind of green walling of environmental protection and energy saving of profit was wiped one's face lagging material.
For solving the problem, it is composed of the following components that the present invention is used for the excellent regeneration aggregate of the adhesive property of exterior wall heat-preserving system thermal insulation mortar of wiping one's face:
Cement 25-35, flyash 15-20, aggregate 22-32, lagging material 10-20, stopping composition 8-16, redispersible latex powder 1-3, anti-crack fiber 0.5-1, admixture 1-3.
As limitation of the invention, aggregate of the present invention is the recycled fine aggregate of the discarded concrete crushing and screening of grade 0.63mm ~ 1.25mm; Described lagging material is the glass bead of 1.0mm ~ 2.5mm particle size range; Described anti-crack fiber is polypropylene fibre, and length is 5mm ~ 12mm; Described stopping composition is pearlstone flocculating aids waste material; Described admixture is hydrophobic type multifunction additive, and Nanothix B1490 wherein can be selected especially as admixture of the present invention.
In addition, the wipe one's face using method of thermal insulation mortar of exterior wall regeneration aggregate of the present invention is that the solution above-mentioned admixture being made into concentration 8% ~ 11% adds in this insulation mortar powder to stir and uses for 5 ~ 6 minutes.
After adopting above-mentioned technical scheme, the present invention compared to existing technology tool has the following advantages:
1, the regeneration aggregate after the present invention utilizes discarded concrete crushing and screening all replaces natural sand.Fine aggregate after crushing and screening is hardened the tiny sand grains of grout parcel often or is the grout grain hardened completely; simultaneously because the effect of the extraneous positive mechanical power of shattering process can cause particle to there is certain crack; when mixing heat-insulating finishing mortar; do not have the cement granules of complete aquation (kernel) that aquation more fully can be continued in recycled fine aggregate; cohesive strength can be increased; recycled fine aggregate light weight more relative to natural sand simultaneously; thermal conductivity is little, can improve whole wall thermal insulating effect.
2, the present invention has done screening control for the particle diameter of glass bead and the particle diameter of regeneration aggregate; a good grating can be reached between the bi-material making to serve as aggregate; mixing mortar has good workability, is easy to constructing operation, also can play good resistancing action to contraction simultaneously.
3, after present invention adds appropriate re-dispersible glue powder, meet to dispersible after water form polymeric film in mortar, the water-retentivity of the thermal insulation mortar newly mixed is improved, and enhancing can serviceability; Polymkeric substance glued membrane is met after water can not twice dispersing, prevents the infiltration of moisture content, improves the weather resistance of exterior wall.
4, present invention adds appropriate pearlstone flocculating aids waste material is adulterant, itself be a kind of industrial waste and there is the granulated material of light thermal-insulation performance, effectively can adjust the grain composition that thermal insulation mortar gathers materials, heat-insulating finishing mortar correlation technique is further improved.
5, product of the present invention has the features such as insulation, fire prevention, bonding and resistance to cleavage are good, has saved natural sand, also can alleviate built-loading simultaneously.The regeneration aggregate thermal insulation mortar thermal conductivity of preparation is low, at 0.1W/ (mK) below, can support the use with regeneration aggregate insulation blocks, avoid the generation of interface cold-heat bridge, solve globality and the weathering resistance of building heat preservation body of wall, make really to realize with buildings the same life-span work-ing life of wall insulation system; Also stopped the disaster hidden-trouble because the independent heat insulating material for external of exterior wall produces simultaneously.
