Description
Technical field
The present invention relates to a kind of lagging material and production technique thereof of construction wall.
Background technology
Modern architecture develops to high level, and requiring used building enclosure is light material.But common light material thermal capacitance is less, causes fluctuations in indoor temperature bigger.This not only causes indoor thermal environment uncomfortable, but also increases air conditioner load, causes building energy consumption to rise.27% of China's building energy consumption account whole nation total energy consumption.The state basic policy of, sustainable development energy-saving and cost-reducing in order to implement, the Ministry of Construction has proposed the new building energy conservation standard in three steps energy-conservation 65%.Reach above-mentioned standard, just must improve traditional wall heat insulation material and construction technology.Traditional building heat preservation lagging material comprises polyphenyl sheet material (EPS), glue powder polyphenyl particle and rigid polyurethane foams, these materials all have single thermal resistance function, its fire prevention, resistance to compression, resistance to cleavage are poor, it is bigger to be affected by climate change, cause potential safety hazard easily, and when burning, can produce toxic substance, be difficult to compliance with environmental protection requirements, also be difficult to reach the standard of building energy conservation 65%.The concrete characteristics of above-mentioned traditional material are as follows:
1, polyphenyl sheet material (EPS)
Crushing resistance: the intensity of sheet material self is low, can only keep its surperficial intensity by cement sand bed, easily destroyed and difficult repairing.
Splitting resistance: sheet material is to combine through piecing together in construction, its stress influence of being heated at the place of piecing together, and generation crack that can different Cheng Du, and because the heat bridge in crack itself reacts, its heat insulation system is damaged and lost efficacy.
Weathering resistance: styrofoam itself is airtight, and coagulates water because the temperature difference produces between sheet material and the main wall body, and the thawing because condensed water is condensed repeatedly makes heat insulation system destroyed under the insulation situation outside.And, belong to the cavity bonding between sheet material and the main wall body, under the effect of negative blast, the danger of being taken off by wind is arranged, Highrise buildings is particularly evident.
Fire line: B1 level or B2 level, material can be softening under the naked light state when fire takes place, and can burn when reaching burning-point, exists safety to draw trouble.
The feature of environmental protection: the gas that produces during the styrofoam burning is the benzene gas of severe toxicity, can cause serious injury human body.
Construction: only limit to regular body of wall and smooth strong face, and want the disposable plates seam, use polymer bonding, smear polymkeric substance again and strengthen its intensity, construction is complicated, needs the construction crew of specialty, influences the duration.
Economy: according to the density of material difference, the price difference is not long in time limitly saved its cost, and the auxiliary material of usefulness is many.
2, glue powder polyphenyl particle
Crushing resistance: granular polystyrene is a major ingredient, because the intensity of granular polystyrene own is not high, so its crushing resistance is not strong, need add sand-cement slurry and carry out surface treatment, improves its intensity.
Splitting resistance: its composition is to be polymerized by granular polystyrene and rubber powder, is difficult for bonding, and the time is long slightly, just can produce hollowing and crack.
Weathering resistance: granular polystyrene belongs to macromolecular substance, and molecular chain is easy to by the factors disrupt in the external world, in case the surface is destroyed, not only influenced the heat retaining property of whole heat insulation system, and in a single day it also can " make moist and ease back " to meet water, and cohesive force is lost and come off, and hidden danger is heavy.
Fire line: B1 level.
The feature of environmental protection: glue powder polyphenyl particle all comes from and reclaims styrofoam and pulverize and form, and the source of recovery is indefinite, and the gas that generates during the granular polystyrene burning also is benzene gas, is highly toxic substance.
Construction: material is in the building-site proportioning, and the granular polystyrene light weight is scattered and disappeared easily, has not only wasted a part of granular polystyrene during proportioning, but also has polluted the building site environment.
Economy: this product is composited by sheet material and rubber powder, and is loosely organized, needs professional contingent during proportioning, technology cost height.
3, rigid polyurethane foams
Crushing resistance: mainly guarantee between the capstock of this material and the polyurethane insulation coating by boundary mortar.
Splitting resistance: more crisp after the drying of starting material own, along with time substrate in weathering process is easy to generate the crack, owing between polyurethane insulation coating and the capstock, also be easy to generate delamination and cause the crack to produce.
Weathering resistance: urethane belongs to petroleum derivative, and ageing resistance is poor, and the time is long more, and the degree of degraded is just heavy more, and temperature is high more, and degree of aging is just fast more.
Fire line: mostly be that the B level is not fired or flammable, in public places, position such as garage uses restricted.
The feature of environmental protection: this product is burning in a single day, and the benzene gas of generation can cause serious burn to the people.And be highly toxic substance.
Construction: do base treatment earlier before the foaming of spray rigid polyurethane, lean on special priming paint to do tack coat, surface treatment is had relatively high expectations to building masonry wall, as cleaning, degree of drying etc., if construction does not reach requirement and will make a big impact to caking ability, just there is hidden danger in security, in addition, surface material guarantees by mortar with combining mainly of urethane, the processing requirement height, otherwise, will cause the adhesion problem between surface material and the urethane, have the secondary potential safety hazard, operational procedure is numerous and diverse, and needs the construction crew of specialty.
Economy: the technology cost is higher.
On the other hand, the research that the phase-change accumulation energy material of construction is applied to building materials starts from nineteen eighty-two, is initiated by USDOE Sunpower Corp..Got up with the technical development that phase change material PCM handles material of construction (as plasterboard, wallboard and concrete member etc.) nineties in 20 century.Subsequently, research and the application of phase change material PCM in material of construction such as concrete test block, gypsum wallboard is in the ascendant always.1999, succeed in developing a kind of New Building Materials-solid-liquid eutectic phase change material abroad again, this phase change material of cast in wallboard or light concrete precoated plate can keep room temp suitable.The America and Europe has many companies to utilize the special-purpose cabin of outdoor communication wiring unit of phase change material PCM production and sales and power transformer equipment in addition, can all remain on suitable working temperature in summer in winter.The recombining process of phase change material and material of construction mainly contains following several method at present: (a) PCM is sealed in the suitable containers.(b) will insert in the material of construction after the PCM sealing.(c) by soaking PCM is infiltrated porous building materials matrix (as gypsum wallboard, cement concrete test block etc.).(d) PCM is directly mixed with material of construction.
