Description
Technical field
The present invention relates to building coating fields, and in particular to a kind of mould proof temperature control type building coating of aqueous, environmental protective and its preparation
Method.
Background technique
It is a principal element for causing environmental pollution that traditional solvent type, which builds evaporated organic compound, with
Volatile organic compounds VOC is directly entered air simultaneously for this, will cause air pollution, to the producer of solvent based coating, applies
Work person and user cause Health cost.With the enhancing of environmental requirement and people's environmental consciousness that country advocates, solvent
Type coating is no longer satisfied daily life requirement, and it has been trend that water paint, which substitutes coatings volatile organic compounds,.
As the improvement of people's living standards, people require also to be gradually increased to the comfort of living environment, with air-conditioning
With a large amount of uses of heating etc., serious energy loss is caused, corresponding building energy consumption greatly improves.
Application of the phase-change material in terms of the field of building materials at present is directly incorporated into cement mostly in open form, exists
The problem of phase-change material leaks in phase transition process, or phase-change material is coated using organic shell material, such as: melamine
Amine-formaldehyde resin etc., there are shell material intensity is not high, poor thermal conductivity causes the temperature control effect of phase-change microcapsule poor.
For example, the patent literature report of publication number CN102190932A is direct direct with expanded perlite by phase-change material
It is compound to constitute compound phase-changing energy storage material, then be mixed to form with the one or more of styrene-acrylic emulsion, pure-acrylic emulsion, vinyl acetate emulsion
Building coating, the phase-change energy-storage composite material is with physisorphtion directly by the porous structure of phase-change material sucking expanded perlite
In, there are the leakage problems of phase-change material during being recycled for multiple times, therefore the thermoregulation effect of phase-change material is bad.
For example, the phase-change material of the patent literature report of publication number CN201210052510 is the complete end-sealed type of melamine
Resin capsule, is directly used in the preparation of Energy-Saving Architectural Coatings, although solving the leakage problem of phase-change material in use,
But its thermal coefficient is relatively low, therefore influences the temperature control effect of phase-change microcapsule.
For example, the patent literature report of publication number CN200610021970 uses melamine formaldehyde resin as shell material
Phase-change microcapsule, for the preparation of Energy-Saving Architectural Coatings, although being added to inorganic constituents in shell material, its thermal coefficient phase
It is still lower for inorganic shell material silica, the same temperature control effect for influencing phase-change microcapsule.
Publication number CN105238361B discloses a kind of multi-functional microcapsule phase-change based on silver/silicon dioxide bilayer wall material
Material and preparation method thereof.The patent induces silver ion to assemble to form bivalve material phase by building sulfydryl silicon dioxide layer wall material
Become material.But silver is metal and oxidizable, is easy to cause to change to microencapsulation material overall performance.
Traditional building coating will play mildew-proof effect, need individually spraying or add mould inhibitor in coating, and city
Mould inhibitor on face is mainly the iodine based compounds such as iodate formaldehyde, iodate propyne derivative and borate metal salt, tributyl tin
Equal organo-tin compounds, the various disadvantages such as bad, toxic or price that there are persistence, publication number CN104017453A are disclosed
A kind of mould proof thermal insulation coatings of non-toxic water microcapsules and preparation method thereof, and played using anti-fouling agent epoxy menadione mould proof
Effect.
Demand based on building trade to the mould proof temperature control coating of novel environment friendly, the present invention provide a kind of silica/phosphoric acid
The compound shell material of silver, microcapsules of the phase-change material as capsule material, in conjunction with organosilicon-modified acrylic resin emulsion etc. with other compositions
Coating, wherein phase-change microcapsule is compared to traditional phase-change material, and the specific surface area of material increases, silica/phosphoric acid
For the compound shell material of silver compared to organic shell material, the thermal coefficient of phase-change microcapsule has obtained significant increase, since silica shell holds
Microcellular structure is easily formed, SDS is adsorbed on silica hole by electrostatic interaction as anionic surfactant, silver ion
In, with the growth of silver orthophosphate, microcellular structure is gradually filled, so that the mechanical strength and compactness of compound shell material are enhanced,
Avoid the leakage problem of paraffin class phase-change material in use.Different with silver-colored simple substance, silver orthophosphate belongs to semiconductor, can
It absorbs photon to generate free radicals, so that antimildew function while it is with anti-microbial property.These are existing building coating industry
It is had not been reported in technology.
