Description

External thermal insulation system is used decoration mortar
Technical field
The present invention relates to a kind of building mortar, specifically is that a kind of external thermal insulation system is used decoration mortar.Belong to the external thermal insulation system facing and use extraordinary dry-mixed mortar.
Background technology
Along with the all-round popularization of China's building energy conservation policy, China various places begin the standard of mandatory execution building energy conservation 50% and 65% respectively.Accomplish above energy conservation standard, most of newly-built and existing building transformation all need be employed in exterior wall to paste expansion polyphenyl plate be main external thermal insulation system.Because of this system is that material by different chemical physical propertiess such as basic unit's body of wall, polymer bonding mortar, expansion polyphenyl plate, fibrous mesh cloth, expansion bolt, polymkeric substance plastering mortar and colored finish layers is composited; The influence of the extraneous destructiveness of consider rain again, avenge, freeze, melt, drying and watering cycle, atmospheric heat stress, blast, seismic force, water and steam, fire and external surging force etc. are many; Accomplish " under correct use and conventional maintenance condition; be no less than 25 years working life "; Just require the material of heat-insulation system and each layer of decorative cover unlike material and characteristic not only will satisfy specific performance properties requirement separately; And require between the layers of material compatible with each otherly, and each other coordinate, form an organic whole.At present academia and industry member to the finishing material that is suitable for this complex system of external wall outer insulation from the combination of theory and practice also shortage go deep into detailed research; And the problem that this is ubiquitous certainly will influence the sound development of External Thermal Insulation Technology for External as conscientiously not solving.Facts have proved: many functions of polymeric trim mortar and characteristics have exactly met the requirement of external thermal insulation system, the supporting outer decorative product of the outer heat preservation system of a kind of excellence of can yet be regarded as.Development and application polychromy mortar and with the external insulating system for thinly plastered external wall that applies to of its science energetically will help to solve outer heat preservation technology at present in the raising of China and perfect.
At present, building energy conservation is in full swing in each department, and along with the rapid intensification in building energy conservation market, size insulation enterprise comes on stage one after another, desires to seize market with the fastest speed.But because most of middle-size and small-size lagging material production and management of construction enterprises are lack of standardization, cause building energy conservation market dragons and fishes jumbled together, adulterate, use inferior materials and turn out substandard goods, the energy-conservation problem ubiquity such as not up to standard of false propaganda, exaggeration effect, the pernicious competition of demanding a lower price, energy conservation project.Many times of completion engineering seldom large-area heat-insulation system occurred and has ftractureed, seeps water, becomes mildewed, and the serious metope large tracts of land that then causes comes off, cause should be energy-conservation engineering cause the bigger wasting of resources on the contrary.This not only directly has influence on owner and client's vital interests, also must cause adverse consequences to the outer insulation cause that has just grown up simultaneously.Had influence on the developer greatly the external wall outer insulation product of not being familiar with has originally been produced " fear " and " repulsion " phychology.
Except that above problem, at present at home, heat insulating is two uncorrelated materials with outer exterior material.Although all propose to select for use in the heat insulation system elastic coating compatible in the different external wall outer insulation standard of country 144,149,158 etc., in theory aspects such as finishing material and heat insulation system consistency and matching also lacked basis and systematic research with system.In practical application, also on the exterior wall heat insulating material for external, use the finishing materials that have major defect in a large number.For example, tiling outside on the very low styrofoam of tensile strength; The aqueous latex paint that external wall outer insulation external coating and heat insulation system life-span are difficult to mate; Use the solvent based coating of meeting corrosion GPPS cystose etc.At present, the research of heat-insulation system finishing material is far away to fall behind the research with heat-insulation system itself, still satisfies aspects such as market is multi-level, diversified requirement with matching heat-insulation system and all has very big distance from finishing material.How guaranteeing the quality of building energy conservation external thermal insulation system, is the common target of pursuing of colleague of being devoted to promote the building energy conservation career development.It is a systems engineering that exterior-wall heat insulation is coated with the decoration system, guarantee construction quality, only relies on that good product is arranged is not enough, and final quality also receives the influence of factors such as engineering-environment, arrangement and method for construction, construction level, system support.Though China's building energy conservation cause has obtained deep development; But because the technology of the complicacy of heat-insulation system and existing enterprise's heat insulation system limitation; The cracking that part external wall outer insulation engineering occurs, peel off, leak and quality problems such as poor durability; Cause the external wall outer insulation engineering not only can not play the effect of heat insulating, even make building basic weather resistance and visual appearance all influenced deeply.According to the systems engineering construction requirement, improve the quality of outer insulation and decoration system, need the common cooperation and the cooperation of system material supply enterprise and construction enterprises, market presses for the quality problems of insulation and decoration system outside the angle of system solves.
Dry-mixed mortar also is called dry-mix, dry-mixed mortar or premix (doing) mortar; Be meant by the professional production manufacturer production, a kind of particulate state or pulverulent mixture that the fine aggregate of handling through dry screened and inorganic binder, water-keeping thickening material, mineral admixture and additive mix by a certain percentage.Dry-mixed mortar helps employing new technology and novel material, improves constructional method, guarantees construction quality, has the meliority of aspects such as high-quality, efficient, energy-conservation, material-saving and environmental protection.Decoration mortar is a kind of novel green material of construction.Dry-mixed mortar is the another novel green material of construction as continue ready mixed concrete after because it has and economizes on resources, protects environment, guarantees construction engineering quality, realizes the premium properties of aspect such as resource reutilization, progressively by people cognition and attention.Its development has not only demonstrated fully the strategy and policy of national realization energy-saving and emission-reduction, also is one of important measures that realize building continuous development.The present employed building mortar of China's building trade, the overwhelming majority is that interim at the construction field (site) preparation is mixed and stirred, and operate miss is big, and it is unsecured to be mixed with quality, and the mortar consumption is many, problems such as construction quality is low, the wasting of resources, environmental pollution that these cause.The mortar that needs some to have specific characteristics and to require at some construction key positions such as tilings, waterproof, fireproofing, the Equipment Foundations secondary cementation of fissures etc.; And the preparation of traditional scene is difficult to reach high quality; Be easy to take place quality problems, this just provides the broad space to greatly developing of premixing mortar.Decoration mortar is a kind of general name with wall plastering of decorative effect; The decoration mortar that wherein makes with the polymer modification dry-mixed mortar is used the most extensive; Just progressively substitute coating, ceramic tile etc. at present as building outer wall decorative material, have the three-dimensional appearance of recovering one's original simplicity, decorative effect is unique naturally; Ventilative cracking resistance, effect is lasting.Present external thermal insulation system influences construction quality with the problem that the decoration mortar ubiquity is prone to fade, water-repellancy is poor, the accumulation of salt in the surface soil is serious.
