Description
Technical field
The present invention relates to a kind of material of construction, especially heat-preserving building mortar
.
Background technology
Along with the raising required building heat preserving heat-proof quality, various lagging material uses and gives birth to, as thermal insulation mortar.Thermal insulation mortar kind is in the market more, take pearlstone as lagging material mostly, agglutinate is made with cement, gypsum etc., this kind of thermal insulation mortar has the features such as inexpensive, fire-resistant, workability is good, but its pearlstone water-intake rate used is very large, and its weight water-intake rate can reach 200 ~ 900%.Shrinking can appear due to dehydration in mortar in setting and harden process, and this stress shrinking generation is the major cause that mortar occurs hollowing, cracking, chaps, comes off.Also some thermal insulation mortar is with polystyrene foam particles (EPS) for lagging material, and this kind of thermal insulation mortar has the advantages such as heat insulation property, chemical resistance be good.But because EPS surface is hydrophobic nature, incompatible with inorganic binder, the workability of this kind of thermal insulation mortar is poor, cohesive strength is low, not easily constructs.In addition the Young's modulus due to EPS is very little, and it is large that the thermal insulation mortar of this thermal insulation mortar particularly low unit weight exists shrinkage strain, the problem that ultimate compression strength is low.
Summary of the invention
The object of the invention is the deficiency existed for prior art, propose a kind of by surface modification lagging material and interpolation agglutinate properties-correcting agent, thus there is the high performance heat-preserving building mortar of the features such as thermal and insulating performance is excellent, cohesiveness good, ultimate compression strength is high, easy construction.
For achieving the above object, the technical solution used in the present invention is as follows:

Described agglutinate is by 20-80%(weight) cement and 80-20%(weight) flyash or 20-80070 (weight) cement and 80-20%(weight) gypsum forms.
Described fiber is the one in polypropylene fibre, lignin fibre, alkali resistant glass fibre.
Described polystyrene foam particles is by the particle of waste polystyrene foam through fragmentation or the particle by foamed polystyrene.
The particle diameter of described polystyrene foam particles is 1 ~ 4mm.
Alkyl in described alkyl dimethyl (2-hydroxyl-3-chloropropyl) ammonium chloride
Carbon atom number is 8 ~ 18.
Described high polymer binder is become to be grouped into by least one in ether of cellulose, polyvinyl alcohol, VAE latex powder, polyacrylamide, sodium polyacrylate.
Described gas tracting subtractive agent is by wooden calcium, sodium abietate, Triton X-100 (OP), and in sodium lauryl sulphate, naphthalene series high-efficiency water-reducing agent, Polycarboxylic Superplasticizer, at least one becomes to be grouped into.
Described activating flyash agent is soda ash and raw aluminite powder or soda ash and alum stone flour.
The present invention carries out modification to agglutinate by adding all kinds of properties-correcting agent, changes its performance, to reach: reduce rigidity, improves flexible, folding/pressure ratio is increased; Improve water-fast, anti-permeability performance; Improve cohesive strength; Reduce unit weight, improve weathering resistance and freeze-thaw resistance; Improve workability.Wherein, by adding gas tracting subtractive agent, reduce firstly the water consumption in mortar use procedure, to improve its intensity, make mortar inside form mutually not through microvesicle simultaneously, reduce its unit weight, improve thermal and insulating performance and freezing and thawing performance, also can play waterproofing and anti-leakage effect simultaneously.The selected macromolecular material of domestic and international advanced person in this external agglutinate properties-correcting agent, after several macromolecular material mixing, mutual collision between macromole and small molecules carries out fracture and the restructuring of molecular chain with attraction, define composite high-molecular material, the flexibility of thermal insulation mortar can be improved like this, make its roll over/pressure ratio increases, and also improves cohesive strength simultaneously, can exempt from conventional basic unit's interface processing.By macromole IPN thickening technology, the toughness of material is strengthened, antiskid pendant ability strengthens, and improves workability simultaneously.
The present invention carries out surface modification, to reach to lagging material (polystyrene foam particles, pearlstone): strengthen EPS and inorganic glue and to contract the consistency of expecting, avoid layering, raising intensity; Reduce the water regain of pearlstone, avoid the cracking that produces therefrom and hollowing: by the EPS of hydrophobic nature is carried out hydrophilic treatment, improve the consistency of itself and inorganic binder; And pearlstone is done the process of part hydrophobic, reduce its water-absorbent, avoid the cracking that produces therefrom and hollowing; EPS after surface modification and pearlstone are made the thermal insulation mortar that lagging material and modified adhesive ramming material are obtained, can play respective advantage, it has energy-conserving and environment-protective, excellent performance, steady quality, cost performance is good, workability is excellent feature.
Compared with prior art, its remarkable advantage is in the present invention: (l) thermal conductivity is little, and thermal and insulating performance is good.Except being except main light skeletal with the EPS of good heat insulating in this mortar, also added gas tracting subtractive agent, after mortar adds water and stirs, atomic small bubbles can be produced under the effect of air entrapment agent, define small and don't through bubble in mortar inside, enhance the heat insulating of mortar, freezing and thawing performance.Also can play waterproofing and anti-leakage effect simultaneously.(2) ultimate compression strength is high, has good workability.Owing to having carried out surface modification treatment to EPS, made EPS particle become wetting ability from hydrophobic nature, add water mix and stir time, the polar group of EPS particle surface absorption just interacts with cement and combines closely, thus effectively improves the ultimate compression strength of product.The modification on EPS surface simultaneously, make EPS particle be easy to be soaked by cement slurry, make it be evenly distributed in cement slurry, avoid EPS appears in general EPS thermal insulation mortar " floating " phenomenon when mixing and stirring, the workability of product is good, plasters laborsaving easy to operate.(3) cohesive strength is high, can exempt from base treatment.Owing to the addition of multiple high polymer binder in mortar, utilize their performances separately and excellent synergistic effect, cohesive strength is improved greatly, this product is used to exempt from base treatment, directly be applied in concrete walls and newly lay bricks in the various building blocks such as wall, occurring without cracking, hollowing, obscission.Be conducive to the adding of high polymer binder the flexibility improving thermal insulation mortar, folding/pressure ratio is increased.(4) seepage control and crack resistance performance is good.Owing to having carried out surface modification to pearlstone, reduce its water regain, made it can not occur shrinkage crack due to a large amount of dehydration in setting and harden process.Also added in this external mortar through special process surface-treated dedicated fiber, homodisperse fiber connection is the three-dimensional point of network had, on the one hand it can support aggregate, the segregation of effective minimizing aggregate, reduce bleeding: the producing and developing that effectively can control the inner microfracture of mortar on the other hand, prevents the generation of crosscutting concern.
