Abstract
An anticracking insulating putty contains proportionally polymer powder, hollow microbeads, white cement, quartz powder, heavy calcium, water preserving agent, antidropping agent, anticracking agent, disperser, defoaming agent and reinforcing fibres. Its advantages are high drying speed, adhesion and flowability, and high resistance to water and high temp.
Description
Technical field the present invention relates to a kind of functional building and ornament materials, in particular for the bottoming of interior exterior wall with scrape the anti-cracking putty of Da Bai.
Background technology is on traditional sense, and building coating is a kind of work in-process, is only final finished through the construction film forming attached to the coating on the body of wall basal plane.In this process, though putty is the supplementary material in the building coating coating process, but playing in metope basic unit and between filming, it forms a connecting link, the vital role of bonding transition is also being born the body of wall apparent mass simultaneously, is being prevented important functions such as metope cracking, the peeling of filming, specific functionality.
Used wall surface putty mainly contains three kinds of physical aspects on the interior exterior wall of traditional architecture at present: (1) is the paste single-component, can be used for on-the-spot directly construction, shelf lives 2-3 month; (2) be two components of liquid and powder, be used for field mix and stir construction, shelf lives 3-5 month; (3) be the powder single-component, need add the water mixing at the scene and stir and to construct, shelf lives 6-12 month.Defectives such as common putty is easy to crack though this wall surface putty of three types can solve to a certain extent, efflorescence, easily mouldy when Mierocrystalline cellulose increases silk fabric, layering caking, but in actual life, tend to body of wall be cracked owing to the variation of temperature, humidity, these problems and then will cause the application metope disadvantages such as paint film to occur have had a strong impact on the visual appearance of external wall.And above putty can produce harm to human body because it has toxicity, and industry gradually is eliminated out.
Along with the appearance of country to building materials hazardous and noxious substances limit standard, the environmental issue of putty, also be subjected to human consumer's extensive concern, how to develop and a kind ofly require environmental protection, energy-conservation, pollution-free, high hiding rare, life-span long, the putty of easy construction and safety is to become the development trend of metope base treatment putty from now on.
Summary of the invention is for the metope of fundamentally avoiding the application exterior wall ftractures, peeling, shedding and quality problems such as peel off, and the selection of supplementary material---putty is very important.The invention discloses the greasy prescription of a kind of heat-insulation and heat-preservation cracking resistance, functional performances such as that this putty not only has is heat insulation, insulation, high temperature resistant, freedom from cracking, but also have thick matter, do soon, easily polishing, strong adhesion, advantages such as water tolerance, good fluidity.In addition, because this putty is so instant packed transportation does not have dust in the granule product construction, easy to use by the single-component powder morphology or be processed into pellet.
This heat-insulation and heat-preservation anti-cracking putty of the present invention, its component content is as follows:
The anti-sagging agent of the coarse whiting of the white cement of the polymer powder of 2-5%, the cenosphere of 5-20%, 20-30%, the silica powder of 25-40%, 25-45%, the water-holding agent of 0.3-0.5%, 0.5-1.0%, the antichecking agent of 0-1.5, the dispersion agent of 0.1-0.5%, the defoamer of 0.1-1.0%, the fortifying fibre of 0.3-1.0%.All percentages are all weight percent, and all component sums are 100%.
Wherein, polymer powder is the multipolymer of pulverous acrylate, this polymer powder is acrylate and the alkylmethacrylate polymer powder that obtains through particular processing technology, can be emulsion dry powder base-materials such as pure third, phenylpropyl alcohol and vinegar third, vinegar uncle.
The cenosphere specification is the nonmetal multifunctional material of lightweight of the special processing of process of 0.2-400 μ m, and main component is SiO
2And Al
2O
3
Filler is the 425# white cement, 400# coarse whiting, 300# silica powder.
Auxiliary agent is: antichecking agent is Loxanol P; Dispersion agent is Hydrolalat 760; Defoamer is Dehydran 1922; Anti-sagging agent is Lomar D (above product is all from Cognis company).
Water-holding agent is the methylcellulose gum series products of molecular weight about 15000-40000.
Used strongthener is that length is the polyacrylonitrile fibre of 1.0-3.0mm; The cross-sectional shape of this fiber is the peanut shape, vertically is the parallel cylindrical cylindricality, and length is the 0.5-12.0 millimeter, and fineness is the 1.5-2.5 dtex, and density is 1.18g/cm
3It is big to have fiber number, characteristics such as intensity height (tensile strength is more than 300Mpa), ductility good (limit elongation is 14-20%), good hydrophilic property, acid-alkali-corrosive-resisting, weathering resistance, photostabilization are good.
The present invention is achieved like this: take by weighing an amount of each component successively according to above-mentioned each component content, fully stirred 15-30 minute with the kneading stirrer, mix powdered after, change granulating working procedure again over to.Common adoptable granulation process has:
(1) extrusion process is as the granulation of vacuum depression bar, list (two) screw rod extruder grain, drum extrusion granulation, to hobbing machine granulation etc.;
(2) fluidization process as the fluidized drying granulation process, utilizes hot gas flow to make object be in fluidized, sprays into an amount of vaporific cakingagent simultaneously, makes dust agglomeration form loose small-particle, finishes mixing, granulation and dry three programs in a container.
Through granulating working procedure, filter out the pellet finished product, be packaged as finished product with the weather-proof dressing bag.During construction, only need in pellet, mix the water of 30-40%,, adjust to suitable viscosity and just can criticize and scraped again with machine or artificial mixing and stirring with weight percent.
Selected starting material in the present invention's prescription, improved the solid content of finished product, make the putty of producing can guarantee enough once batch scrape thickness, also strengthened the heat-insulation and heat-preservation effect of interior exterior wall simultaneously, putty layer cracking, efflorescence have effectively been prevented, and can stop the variation of body of wall Yin Wendu and humidity and the be full of cracks that produces, and then reduce the probability of coating cracking, improved the quality of finishing system.Compare with traditional wall putty, the putty that uses this prescription to produce has thick matter, fast does, easily polishing, strong adhesion, and advantages such as water tolerance, good fluidity are particularly useful for that the body of wall requirement is heat insulation, insulation, high temperature resistant, freedom from cracking place.
