Description
Technical field
The present invention relates to technical field of inorganic nonmetallic materials, be specifically related to the building heat insulating exterior wall thermal insulating coating that a kind of water tolerance is strong.
Background technology
After 20 century 70s, world climate warms, and earth energy is increasingly exhausted.In AND ENERGY RESOURCES CONSUMPTION IN CHINA, building energy consumption accounts for the 30-40% of mankind's energy consumption, and improving building heat preserving heat-proof quality is save energy, the important channel of improving buildings using function.Thermal insulating coating is applied over the temperature that building surface can effectively reduce building surface and inside.In recent years, along with the popularization of building energy conservation, thermal insulating coating more and more receives the concern of people because of advantages such as economic, convenient and good heat-insulation effect.Therefore, research and develop the daily life of novel, compound insulating mold coating to the mankind to be of great immediate significance.
Existing insulating mold coating mainly adopts organic polymeric emulsions, cenosphere, the heat insulation color stuffing such as porous filler and heat-reflecting material reaches heat insulating, the object of water proof anti-soil, a kind of counter radiation thermal insulating coating disclosed in Chinese patent ZL99114454.6, a kind of aquosity elastic heat preserving insulating paint and preparation method thereof disclosed in ZL200710075800.X, insulating mold coating disclosed in ZL200910061883.6, a kind of thermal insulating coating and uses thereof disclosed in ZL200510000149.0, a kind of thermal insulating coating etc. reflecting solar heat ray disclosed in ZL200710035834.6.Disclosed in its Patent ZL200710035834.6, a kind of thermal insulating coating reflecting solar heat ray is made up of bottom-coating and painting coating, and primary coat adopts hollow beads lagging material, heat-reflecting material and macromolecule resin to make; Face is coated with and adopts Surface coating reverberation ray matrix material, heat-reflecting material and macromolecule resin to make, owing to containing the extinction groups such as a large amount of-C=0 ,-C-0-C ,-0H in organic polymer, inorganic color stuffing is higher than to the degree of absorption of sunlight, so when the addition of organic polymeric emulsions is larger, film is also larger to the absorbed dose of sunlight, the thermal conductivity of film also can correspondingly improve, and can reduce the effect of heat insulation of coating.In order to reach the basic process based prediction model requirement of common exterior coating, this kind of existing traditional thermal insulating coating must ensure the higher addition of organic polymeric emulsions in coating, causes its effect of heat insulation undesirable.And not there is elasticity, resistance to cleavage, in use receive many restrictions.
Summary of the invention
It is simple that technical problem to be solved by this invention is to improve a kind of preparation, the building heat insulating exterior wall thermal insulating coating that water tolerance is strong.
Technical problem to be solved by this invention realizes by the following technical solutions:
The building heat insulating exterior wall thermal insulating coating that a kind of water tolerance is strong, it is characterized in that, be made up of the component of following mass percent: modified clay 5%, rare-earth light conversion agent 2%, pure-acrylic emulsion 40%, polyurethane thickener 5%, sodium laurylsulfonate 2%, silane coupling agent 1%, polyether glycol 4%, talcum powder 20%, polyisocyanates 3%, hydroxy silicon oil 3%, fire retardant 5%, defoamer 2%, propyl carbinol 6%, nano silicon 2%.
Pure-acrylic emulsion has the flexibility of macromolecular material, has again excellent water resistance, and the weathering resistance of excellence and sticking power, coordinates, can strengthen the water tolerance of coating, heat-insulating property with modified clay, rare-earth light conversion agent etc.The fusion performance that tetrahydrofuran (THF) can promote each component in coating is greatly added in coating.
The preparation method of above-mentioned modified clay is as follows:
1) clay is toasted 30-40 minute in the roasting plant of temperature 86-95 DEG C, be then cooled to normal temperature rapidly, pulverized 60 eye mesh screens, and obtained clay powder stand-by;
2) by clay powder with dehydrated alcohol be dispersion medium, wherein the mass ratio of powder and dehydrated alcohol is 1:30, ultrasonic disperse 1 hour on supersonic cleaning machine;
3) powder through ultrasonic disperse being put into nylon ball grinder, take agate ball as abrading-ball, and ball material mass ratio is 7:1, is under the condition of 150 revs/min at rotating speed, continuous ball milling 2 hours in planetary ball mill;
4) powder complete for ball milling is poured in powder dish together with agate abrading-ball, dry at 80 DEG C;
5) powder of drying is sieved, take out agate abrading-ball, then ground by powder mix, till the larger reunion of nothing, so far, the preparation of modified clay is complete.
Coating of the present invention is applicable to: the 1) waterproof of the energy-conservation application in the skin face such as building exterior wall face, concrete roof, concrete, sand-cement slurry, masonry, exterior-wall heat insulation basic unit and roofing and metope, cracking resistance, fire prevention, fire-retardant; 2) heat-insulation and heat-preservation of pipeline, the energy-conservation application of color steel roofing and waterproof.
The invention has the beneficial effects as follows: (1) water tolerance and good heat preservation performance; (2) preparation technology is simple, and finished product is nonpoisonous and tasteless, environmental protection; (3) can save and not degenerate for a long time; (4) good leveling property, strong adhesion when spreading; (5) do not chap after long-time use, do not come off.
