Description
Technical field
The present invention relates to building heat preservation decoration material field, particularly external wall Surgery therapy flexible finishing material of flame retardant type and preparation method thereof.
Background technology
Along with the quickening of urbanization process, high buildings and large mansions quantity gets more and more, and highly more and more higher, style is more novel, unique, and this proposes more and more higher requirement to building and ornament materials.Traditional ceramics face brick is made mainly through high temperature sintering, and not only production cost is high, and energy consumption is high, and exists than great, can not deformation, and poor air permeability, the disadvantages such as high-altitude safe hidden danger is large, can not adapt to the requirement of modem architectural ornament.Although exterior coating various colors, ornamental comparatively strong, the problems such as single function and durable, resistance to soiling cause its market share in building decoration field and little.In recent years, take porcelain tendre as the imitative ceramic tile of representative, imitative stone materials high-polymer decorative material owing to there is unique snappiness, lower proportion, the expressive force of good fire prevention, waterproof, ventilation property and excellence is shown up prominently in exterior wall finish material.But prior art (disclosing 200810026831.0,201010225614.1,201010225624.5 see Chinese patent) mainly concentrates on the expressive force improving product, product itself there is no heat insulation function, in practice of construction process, coordinate the heat preservation plate material such as polystyrene, urethane to use toward contact, this is complicated construction technique not only, and due to the rigidity of warming plate, the flexible advantage of porcelain tendre is difficult to embody.In addition, the introducing of a large amount of organic insulation material adds the fire safety evaluating hidden danger of buildings, and this also greatly limit the application of the finishing materials such as porcelain tendre.Silicon oil modified natural earth discloses 201210396329.5 with reference to Chinese patent.
For above problem, the present invention is by having the inorganic hollow filler of heat insulation function and have a kind of architectural decoration matrix material of earth combination preparation of anti-flaming function, it had both remained the advantages such as high-polymer decorative material flexibility is good, proportion is low, good waterproof performance, have again fire-retardant, insulation and decoration functions concurrently simultaneously, be specially adapted to Highrise buildings exterior finish engineering, old city is transformed, the exterior trim surface layer of integrated plate for heat insulation and the irregular building such as curved wall, arch post surface-veneer engineered etc.
Summary of the invention
The object of the present invention is to provide flexible heat-preserving decorative facing of building material of a kind of flame retardant type and preparation method thereof.This finishing material combines that inorganic hollow filler is fire-retardant, the characteristic of insulation and organic polymer resin proportion is low, snappiness good, be easy to the advantage such as shaping, and production process environmental protection, construction process is simple and easy to do, is a kind of desirable architectural coating engineering materials.
In order to realize foregoing invention object, the technical solution used in the present invention is as follows:
The flexible heat-preserving decorative facing of building material of a kind of flame retardant type provided by the invention is primarily of the cavity filling of mud powder, finishing, flexible emulsion, auxiliary agent and water composition, and each raw materials quality number is as follows:
Mud powder: 1 ~ 50
Cavity filling: 1 ~ 50
Fortifying fibre: 1 ~ 10
Flexible emulsion: 10 ~ 50
Pigment: 0 ~ 1
Auxiliary agent: 1 ~ 10
Water: 10 ~ 40.
Better scheme is:
The cavity filling of mud powder, finishing, fortifying fibre, flexible emulsion, auxiliary agent and water composition, each raw materials quality number is as follows:
Mud powder: 10 ~ 40
Cavity filling: 15 ~ 30
Fortifying fibre: 2 ~ 6
Flexible emulsion: 15 ~ 30
Pigment: 0 ~ 1
Auxiliary agent: 1 ~ 8
Water: 10 ~ 40.
In above-mentioned raw materials composition: mud powder is natural mud powder or through silicon oil modified natural mud powder.Natural mud powder is one or more in recessed soil, sand, kaolin, montmorillonite soil, native, the wilkinite of illite, and median size is 100 ~ 500 orders; Cavity filling be containing/not containing one or more in the mica powder of finishing coat, fly ash float, hollow glass micropearl, expanded vermiculite, pearlstone; Finishing coat is nano silicon or nano titanium oxide; Flexible emulsion main component is ambient self-crosslinking core-shell acrylic lipin polymer, and its second-order transition temperature is within the scope of-30 ~-5 DEG C, and solid content is 40 ~ 55%; Fortifying fibre is one or both in trevira, glass fibre, and Fibre diameter is 2 ~ 25 μm, and length is 3 ~ 9mm; Auxiliary agent comprises dispersion agent, defoamer, linking agent, wetting agent, thickening material, anti-aging agent or adds other auxiliary agents known, and wherein linking agent is one or more in butyl (tetra) titanate, vinylformic acid, pentaerythritol triacrylate; Anti-aging agent is one or more in 2-(2 '-hydroxyl-3 '-the tertiary butyl-5 '-aminomethyl phenyl)-5-chlorinated benzotriazole, ESCALOL 567, Octabenzone, two (3.5-di-t-butyl-4 hydroxybenzyl phosphate mono ethyl ester) nickel.
The flexible heat-preserving decorative facing of building material of a kind of flame retardant type provided by the invention comprises following preparation method:
(1) natural earth obtains natural mud powder after eluriating, precipitate, filter, dry, pulverize, crossing 100 ~ 500 mesh sieves; The method of silicon oil modified natural earth is with reference to patent 201210396329.5.
(2) the mud powder utilizing high speed dispersor step (1) to be obtained under 600 ~ 1500r/min speed is mixed into cavity filling, flexible emulsion, auxiliary agent and water the slurry that viscosity is 7 ~ 10Pa.s by a certain percentage; The surface modification method of cavity filling is the wherein one in patent 200610127227.8,200810127094.3,201110377672.0 supplying methods.
