Description
Technical field
The invention belongs to the technical field of solar energy heat absorbing material, a kind of solar energy heat absorbing coating and its preparation are particularly related to
Methods and applications.
Background technique
Solar water heater is the heating device for converting solar energy to thermal energy, by water from low-temperature heat to high temperature, with
Meet hot water needs of the people in life, production.The structure of solar water heater mainly includes heat collector, water tank and bracket
Deng related spare and accessory parts, solar energy is converted into thermal energy by heat collector by solar water heater, thus to the cold water in water tank into
Row heating, to obtain hot water.
As shown in Figure 1 and Figure 2, the heat collector of existing solar water heater is usually the heat absorbing sheet for having certain wide cut
(11) it is welded with the positive displacement runner being made of pipeline (22), heat absorbing sheet (11) absorbs the logical heat transfer of sunlight and passes heat
The medium being directed in pipeline (22), completes the absorption of solar energy.This heat collector is due to being that the coating on heat absorbing sheet (11) leads to
It crosses pad to connect with pipeline (22), contact as linear structure, contact area is small, heat sufficiently cannot be conducted to medium.And
And the medium pipeline (22) that existing heat collector is welded is thinner, diameter is small, can only have circulatory function, cannot achieve heat accumulation
Function, thermal efficiency utilization rate are low.Meanwhile the matching of existing solar energy heat absorbing coating formulation is unreasonable, heat absorption efficiency is low, and heat passes
It is slow to lead rate, causes heat waste.
Summary of the invention
The object of the present invention is to provide a kind of solar energy heat absorbing coating and its preparation method and application, solve the prior art
Middle solar energy heat absorbing coating heat absorption efficiency is low and heat conduction velocity is slow and the problem of cause heat waste.
A kind of solar energy heat absorbing coating of the invention, is mainly realized by the following technical programs: including with
The raw material of lower weight percentage: polyethylene terephthalate resin 60-70%, vinyl chloride-ethylene isobutyl ether 5-15% glue
Mixture 5-15%, black absorbing material 5-12%, age resister 0-1%.Solar energy heat absorbing coating of the invention includes poly- to benzene
Dicarboxylic acid ethyl ester resin, vinyl chloride-ethylene isobutyl ether, adhesive, black absorbing material and age resister are a kind of black
Epoxy coating, endothermic effect is good, and heat absorption efficiency is high, and ageing-resistant, long service life, paint ingredient is environment friendly and pollution-free, cost
It is low.
Embodiment as one preferred, described adhesive are acrylic resin modified polyorganosiloxane.Propylene of the present invention
Acid resin modified polyorganosiloxane is as adhesive, and excellent performance, using effect is good, is conducive to the attachment of solar energy heat absorbing coating,
Its adhesive force is enhanced, its service life is extended.
Embodiment as one preferred, the black absorbing material are any one in barium sulphide or ferrous sulfide
Or two kinds.The present invention using the sulphur barium salt or sulphur molysite or two kinds of mixture of technical grade as black absorbing material, both
Substance source is wide, cheap, and performance is stablized, and endothermic effect is good, and weatherability and UV resistant performance are good, economical and practical.
Embodiment as one preferred, the black absorbing material are barium sulphide or ferrous sulfide according to 2-10:1's
The mixture of weight ratio composition.Present invention preferably uses sulphur barium salts and sulphur molysite according to the weight ratio composition of 2-10:1, i.e. sulphur barium
Percentage composition of the salt in entire formula is about 4-10%, and percentage composition of the sulphur barium salt in entire formula is about 1-2%；It is this
The black absorbing material of composition is matched, more preferably, performance is more stable for endothermic effect, and it is unattenuated using absorbent properties for a long time,
The service life is longer.
Embodiment as one preferred, the age resister are aluminosilicate.Using aluminosilicate as anti-aging
Agent, anti-aging property is good, good with other materials compatibilities, it is easier to form uniform coating, composite material preferably adheres to
In substrate surface, product bulk life time is improved.
A kind of preparation method of solar energy heat absorbing coating of the invention, is mainly realized by the following technical programs
: the following steps are included: 1) taking polyethylene terephthalate resin, it is ground into the particle that size is 3-5mm, it is spare；2) chlorine is taken
Ethylene-vinyl isobutyl ether, adhesive, black absorbing material and age resister are added in particle obtained by step 1), mix 1-
5min；3) mixture obtained by step 2) being added in single screw rod or double screw extruder and is squeezed, machine cavity temperature is 75-85 DEG C,
Extruder head temperature is 90-96 DEG C, and mean residence time is no more than 1min, and cooling, tabletting machine is cooling, crushes, obtains solar energy
Heat-absorbing paint.
A kind of solar absorber of the invention, is mainly realized: by the following technical programs including by gold
Belong to heat absorption flow channel made of material, the inner surface of the heat absorption flow channel is equipped with the first corrosion-inhibiting coating, the heat absorption flow channel it is outer
Surface is equipped with the second corrosion-inhibiting coating, is additionally provided with absorber coatings, the absorber coatings on the outer surface of second corrosion-inhibiting coating
