The heat insulating foamed polystyrene particle mortar used in building engineering consists of portland cement 40-45 wt%, flyash 3-6 wt%, fine silica powder 0-3 wt%, foamed polystyrene particle 1.3-2.8 wt%, polypropylene fiber 0.1-0.2 wt%, quartzite 42-47 wt% and water-thinned silane/siloxane emulsion 5-8 wt%. The present invention has light bulk weight, dry density 300-480 kg/cu m; good heat insulating and sound isolating performance, and heat conducting coefficient 0.07-0.13 W/m.k. The present invention utilizes partial flyash to replace cement and the product has no environment pollution.
Description
Technical field
The present invention relates to a kind of building mortar, specifically is a kind of polystyrene foamed particle heat insulation mortar.Be used for the building material engineering technical field.
Background technology
At present, country is greatly developing and is advocating environmental protection, energy-saving building structure.Implement building energy conservation and must increase substantially peripheral structure, especially the thermal property of exterior wall.But it is unpractical will generally adopting the composite energy-saving wall material at China Yangtze valley and southern area in a short time.And, being used to build by laying bricks or stones these heat-insulating light materials for walls and mostly adopting Portland cement or mix masonry mortar, the apparent density of this class mortar is generally 1600～1800kg/m
3, thermal conductivity is 0.8～1.0W/ (mK), and the apparent density of light heat insulation blocks is generally 450～950kg/m
3, thermal conductivity is 0.15W～0.35W/ (mK), because both thermal conductivity gaps are bigger, causes whole masonry to have " cold bridge " phenomenon, reaches about 25% by building the power loss that mortar joint causes by laying bricks or stones, has a strong impact on the building energy conservation effect.Therefore, development has wiping one's face of insulation insulating energy-saving functional type and masonry mortar seems very necessary.
Find through literature search prior art, she stands in " flyash " the 4th phase 2002, P12-15 writes articles " development of high-performance flyash composite thermal insulation mortar ", and this article proposes to adopt admixture to float pearl and pearlstone carries out modification to mortar, reaches heat insulating effect.Result of study shows that this thermal insulation mortar heat insulation effect is better, and its thermal conductivity reaches 0.1742W/mk.But the composite thermal insulation mortar that this article proposes is on the high side, and construction is complicated, and is difficult to solve problems such as crack that the construction back takes place, hollowing.More single on function, can't satisfy the requirement of modern architecture, as sound insulation, environmental protection and lightweight etc. to other building performance of thermal insulation mortar.
Summary of the invention
The objective of the invention is at deficiency of the prior art and defective, a kind of polystyrene foamed particle heat insulation mortar is provided, make that it has that thermal conductivity is low, unit weight gently, do not ftracture, not hollowing, insulation, soundproof effect good, save characteristics such as the energy, production cost are low, nontoxic pollution-free, the thermal insulation of being convenient to construct, sound insulation.
The present invention is achieved by the following technical solutions, and each component of the present invention and weight percent thereof are:
Silicate cement 40～45%
Flyash 3～6%
SILICA FUME 0～3%
Polystyrene foam particles 1.4～2.8%
Polypropylene fibre 0.1～0.2%
Quartz sand 42～47%
Aqueous silane/silicone emulsion (solid content) 5～8%
The present invention is by polystyrene foam particles, silicate cement, flyash, SILICA FUME, aqueous silane, and polypropylene fibre and quartz sand mix packed forming by a certain percentage.Mainly be utilize aqueous silane at first p-poly-phenyl vinyl foam particle surface carry out modification, improve itself and cement slurry interface binding intensity, adopt SILICA FUME and flyash partly to replace flowability and the water-retentivity of cement simultaneously to improve the mortar mix.For preventing cracking and hollowing to occur behind the sand finish, in the mortar mix, mix the fine PP fiber of certain volume content.Its existing higher bonding strength has wide construction adaptability again, simultaneously owing to be mixed with polystyrene foam particles, thereby reaches insulation, sound insulation, multiple function such as heat insulation.
The starting material that the present invention adopts: cement should be selected the silicate cement of 42.5 strength grades for use, and flyash should be selected II level flyash for use; The quartz sand fineness is controlled at 20～50 orders, and the polystyrene foam particles particle diameter is elected 1.5～3.0mm as, and polypropylene fibre length should be controlled to be 5～15mm, and diameter is 30～50um.The free water content of each component is controlled at below 0.5%.
Take by weighing various starting material by formula rate, the alkane emulsion of at first water-based siloxanes or silicon being itched adds polystyrene foam particles, stir, with this mixture oven dry, add SILICA FUME, silicate cement, flyash, quartz sand and polypropylene fibre then and stir the formation product, pack.
The present invention compares advantage with other lagging material and is: unit weight is light, and dry density is 300～480kg/m
3The heat preservation and soundproof performance is good, and thermal conductivity is 0.07～0.13W/mk; In starting material, adopt flyash partly to replace cement, be utilization of waste material, can reduce pollution, reduce cement consumption in addition, save the energy environment; Stable physical property does not ftracture, hollowing not, and is anti-aging, long service life, because this product adds water and just can use, so easy to use, can realize civilized construction; Adhesive property is good, and is firm with metope and floor bonding; Product is nontoxic, tasteless, and is harmless, free from environmental pollution, belongs to the environment-friendly type heat insulating energy saving material.
Embodiment
Provide following examples below in conjunction with content of the present invention:
The polystyrene foamed particle heat insulation mortar, take by weighing various starting material by formula rate, the alkane emulsion of at first water-based siloxanes or silicon being itched adds polystyrene foam particles, stir, with this mixture oven dry, add SILICA FUME, silicate cement, flyash, quartz sand and polypropylene fibre then and stir the formation product, pack.According to the engineering application need,, can obtain needed performance by adjusting the invention prescription.In specific implementation process, each weight percentages of components is:
Said components gets the polystyrene foamed particle heat insulation mortar dry powder by aforementioned prepared, adds suitable quantity of water, makes mortar mix denseness reach 80mm, presses standard-required moulding sample.The denseness of mortar, delamination degree, unit weight, ultimate compression strength are undertaken by JGJ 70-90 " testing method of building mortar fundamental property "; The cohesive strength of mortar is with reference to JGJ 110-98 " construction work cohesive strength of decorative tile inspecting standard is carried out ", the thermal conductivity of mortar is measured with reference to JGJ51-90 " light aggregate concrete technical regulation ", test specimen natural curing 28d, dry to constant weight, measure with thermal pulse method heat conducting coefficient measuring device.Its test parameter performance index see the following form.
