Description
Technical field
The present invention relates to a kind of insulating moulding coating, concretely relates to a kind of skin recoating and is applied with heat-reflecting heat-insulating
Material, and the preparation method of the heat-reflecting insulating coating.
Background technology
Insulating moulding coating is by obstructing, reflecting, the mechanism such as radiating and reduce the thermal accumlation inside coated article, so as to reach
It is energy saving and improve working environment or it is safe the purpose of a kind of functional coating.Insulating moulding coating is generally divided into isolation-type, reflection
Type and Radiation Heat-insulated Paint three classes.Reflective insulation coating is mainly used in heat-insulated occasion in building engineering field, that is, exists
The surface of peripheral structure uses high reflectivity insulating moulding coating, can reduce absorption of the building to solar radiant heat, prevent to build
Build thing surface temperature caused by absorbing solar radiation to raise, reduce heat and be passed to indoor.
With the appearance of building energy-saving standard, and " green building " field referred to extensively, all it is to advocate effectively
Heat-insulation and heat-preservation, environmental protection, saves the energy.The good new material of development low energy consumption, thermal and insulating performance becomes main trend.Build
The energy saving building authentication system if portion carried out in an all-round way from 2007.Now on the occasion of the nineties in last century and 2000 or so commodity
The building inside and outside walls such as room, office building, hotel and factory recoat peak time, and the house wall in this period is not protected largely
Temperature processing, if the upper heat-reflecting insulating coating of exterior wall recoating, will largely reduce air-conditioning uses duration.
The content of the invention
It is an object of the invention to provide a kind of skin recoating heat-reflecting insulating coating, and the heat reflection every
The preparation method of hot coating.
The adopted technical solution is that：
A kind of skin recoating heat-reflecting insulating coating, it is made of the component of following parts by weight：Alcohol-soluble
15~20 parts of acrylic resin A, 30~35 parts of alcohol-soluble acrylic resin B, 20~25 parts of titanium dioxide, hollow glass micropearl 4
~6 parts, 8~12 parts of hollow ceramic microspheres, 0.5~1 part of silane coupling agent, 0.5~0.8 part of dispersant, defoamer 0.3~0.5
Part, 0.2~0.6 part of levelling agent, 8~14 parts of isopropanol；The alcohol-soluble acrylic resin A is DIRANSA companies of Argentina
Admittedly containing ethanol solution, (THYON SR762 resins are clear solid granules to the 40% of THYON SR762 resins, and glass transition temperature is
76 DEG C, molecular weight 15600,4 are pressed using preceding by SR762 and ethanol:6 mass ratioes are blended in dispersion tank, after soaking 12h, slowly
Speed stirs evenly, 40% admittedly viscosity containing ethanol solution be 55cP)；Alcohol-soluble acrylic resin B has for section's ancient cooking vessel functional material
Limit companyMR1715 resins (MR1715 is acrylic resin modified for a high adhesion force ethanol-soluble type, is clear to micro emulsion
Liquid, solids content (50 ± 2%), 1500~2500cps/30 DEG C of viscosity, 18~30mgkOH/g of acid value, solvent are ethanol, glass
Glass temperature is 35 DEG C).
The preparation method of above-mentioned skin recoating heat-reflecting insulating coating, comprises the following steps：
A weighs each raw material by above-mentioned weight；
Silane coupling agent is uniformly mixed by b with isopropanol, is then divided into two parts, and hollow ceramic microspheres are added thereto portion
Middle immersion, obtains standby material one, hollow glass micropearl is added in another and is soaked, and obtains standby material two；
Alcohol-soluble acrylic resin A, titanium dioxide, standby material one, dispersant, defoamer and levelling agent are added system by c in the lump
In paint can, stir evenly, ground with sand mill；
After the completion of Step d c, alcohol-soluble acrylic resin B and standby material two are added into painting tank, is stirred evenly, filtered,
Up to heat-reflecting insulating coating.
In step b：When the soaking time is 24 small.
In step c：Mixing speed is 1500~1800r/min.
In step d：Mixing speed is 800~1200r/min.
The method have the benefit that：
(1) solvent is used as using ethanol, isopropanol so that coating greatly reduces the pollution to environment in film forming procedure.
Coating application technique is simple, and roller coat, aerial spraying, airless spraying mode can be taken to form a film.Coating easily forms a film, can be in ring
Very fast drying and forming-film under the temperature and humidity of border, the drawbacks of overcoming water paint constructional difficulties.
(2) using ethanol, isopropanol as diluent, recoated on the old coating of water-based, oiliness, be not in come off, lifting, rise
Phenomena such as drum, coating is fine and close, thickness uniform, controllable.
(3) the alcohol-soluble acrylic resin of different glass temperature is arranged in pairs or groups use in proportion, has taken into account the low temperature of film
Splitting resistance and the anti-after-tackiness of high temperature.
(4) silane coupling agent is added in coating：Alcohol-soluble acrylic resin is since carboxyl-content is high, poor water resistance, silane
Coupling agent is added in coating, largely degree of the carrying water resistance and adhesive force of coating；Silane coupling agent is allowed to be uniformly adhered to
Cenosphere surface, improves the dispersion stabilization and cohesive force of cenosphere.
On the whole, the heat-reflecting insulating coating obtained by the present invention is using alcohols solvent as solvent or diluent, with alcohol-soluble thermoplasticity
Acrylic resin is base-material, and coating not containing benezene, esters, ketones solvent in itself, production and work progress environmental pollution are light, can
Directly it is painted on the old coating of water-based or solvent type exterior wall, does not have adverse reaction to water, the old coating of oiliness, application is convenient, film
Thin, adhesive force is good, and application property is good, is not in lifting, depainting phenomenon, and heat reflection, heat insulation are obvious, suitable for house, work
The external wall recoating application such as factory, can reduce and shorten the cooling system usage time such as air-conditioning, save energy consumption.
