Background technology:
External Thermal Insulation Technology for External is an important energy-saving building technology that reduces building energy consumption by reduction exterior wall thermal conductivity.The external wall heat insulation system that generally uses in the world originates from the Europe of the sixties in 20th century now, and it adopts polystyrene foam or hard polyurethane foam as insulating, links together by tackiness agent and body of wall.Because these foam materialss are high molecular polymers of difficult degradation, itself are exactly pollutent, often pollute at the construction field (site), not easy to clean.And, use this external wall heat insulation system in a large number because work-ing life is short, be difficult to the environmental pollutant of degrading in a large number will inevitably producing in the future.In addition, existing external-wall exterior insulation layer difficulty of construction is big, operation is many, time-consuming, general exterior-wall heat insulation is the operation in 8 roads (the cystose surface is smeared tackiness agent, pasted cystose, nail mounting block, cystose surface are smeared polymer mortar, shop glass fiber reticular cloth, surface batch cover outer decorative layer such as exterior coating, brushing paint preferably such as anti-cracking behavior water repellency of polymer mortar, furring brick or brushing and weathering resistance) nearly, need between each procedure to cooperate closely, all linked with one another, strict to the workmen, mistake is arranged slightly, just influence total quality.Because cellular insulant self exists structural fatal defective, so the insulation surface layer ftractures, obscission is serious.And owing to thermal insulation layer designs irrational reason, bubble, bubble phenomenon often appear in thermal insulation wall surface.Even more serious can produce a large amount of hypertoxic gas when being the polystyrene foam burning, fact proved, after fire appearred in buildings, it was a major reason that causes many fire injures and deaths that the poison gas that the polystyrene foam burning produces is poisoned to death human body.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of environmental protection and energy saving thermal-insulated external-wall coating is provided.It is a kind of pair of component stiff shape coating that is made by the tackiness agent of base-material, auxiliary agent, natural silicate fiber, silicate and an amount of light filler.Since adopted high-melting-point, low-density pearlstone as heat-insulation base material, acryloid cement and silicate as tackiness agent, so this coating has very strong sticking power, height alkali resistance and water resisting property, have high flame retardant simultaneously.
Pearlstone is to be expanded to 10~40 times by a kind of vitreous rock by high-tech to form microvoid structure, thereby coating is made up of the space of a large amount of closure, but lower density is arranged, and has guaranteed stronger insulation, the heat-proof quality of coating.The fusing point of pearlstone is 1300 ℃~1350 ℃ in addition, and this has just determined this product high flame retardancy.
Technical scheme of the present invention is: a kind of environmental protection and energy saving thermal-insulated external-wall coating, contain following component materials (weight percent meter): polyvinyl alcohol liquid 5%~10%, acryloid cement 20~40%, cellulose solution 10%~20%, fibrous wollastonite powder 10~30%, sea bubble powder 2~5%, fibrous magnesium silicate 1~4%, pearlstone 5~12%, water 10~30%.
A kind of environmental protection and energy saving thermal-insulated external-wall coating provided by the present invention can single-component or the use of two component.As long as above-mentioned slurry is mixed the back fully to be stirred, form the direct brushing body of wall of stiff shape slurry and get final product when single-component uses.
The present invention can also use by two components, and another powder batching (weight percent meter) is: white portland cement 10~40% and promotor 5%~12%.Slurry and powder are paste construction material according to certain proportioning mixing and stirring, adopt the method for direct blade coating, can disposable solution construction material and the bonding problem of basic unit.
The present invention compares with existing various exterior wall heat-insulating paints, has the following advantages:
1. fire-retardant smokeless, show more high-quality fire performance.Because all raw material that this product adopted all is the product that generates high heat stability behind natural mineral and the auxiliary agent generation chemical reaction.Under the high temperature more than 1300 degree, reach the zero mass loss, zero char volume.When fire takes place, not only do not have naked light, and do not produce thick smoke.
2. cracking resistance, slip-off preventing.Because the starting material that this product adopted all are natural mineral, the cohesive strength height, dynamically anti-cracking performance is strong.It is low to have rate of expansion, and the characteristics that temperature resistance becomes can effectively prevent cracking, and the phenomenon that comes off takes place, and has prolonged the work-ing life of heat insulation coating widely, reaches the quality more than 20 years.
3. operation has only together, has saved artificial greatly.Engineering, house ornamentation all can.This product adopts two 5: 1 proportionings of component, directly brushes after the mixing to get final product on naked wall, and construction is equally convenient with using common exterior wall putty.Not only be fit to engineering and just build, be equally applicable to house decoration.
4. cost is low.Owing to adopt two component proportionings, only need mix and stir in proportion, blade coating 3mm~5mm can reach heat insulation effect.Operation is simplified greatly, has reduced great amount of manpower, material resources.And construction in later period is convenient equally, can furring brick, also can brush all kinds of ornamental finish paints.Coating all has good thermal resistance under the situation of different thickness, remedied the gage distortion that may bring in the construction and influence the defective of heat insulation effect.
5. energy-saving and cost-reducing.This product thermal conductivity is 0.06, satisfy " covil construction energy-saving design standard (heating residential architecture P branch) " JGJ26-95 regulation reach building energy conservation 50% time to the requirement of wall thermal insulating.
