The heat-insulation and heat-absorption integrated coating has solar energy absorption and heat insulation functions, and the weather resistance, temperature resistance and mechanical property of the coating are also relatively good, so that the heat-insulation and heat-absorption integrated coating is particularly suitable for the fields of solar energy collectors, green houses and the like.
Description
Technical field
The present invention relates to a kind of coating, particularly relate to a kind of heat insulation and heat absorption integrative paint, belong to chemical technology field.
Background technology
Thermal insulation coatings is a kind of novel lagging material, realizes a kind of coating of heat-insulation and heat-preservation by low thermal conductivity and high thermal resistance.Thermal insulation coatings can extensively should be in industries such as building, chemical industry, metallurgy, boats and ships, space flight, be mainly used in occasion heat insulation or insulation (cold insulation), coating has good sticking power, can be used for steel, cast iron, aluminium, copper, magnesium, steel stone material, timber, pottery, glass, textiles, plastics, paper, and various coatingsurface.The anti-enzyme environment-friendly and energy-efficient of the heat-proof insulation waterproof fire retardant anticorrosion insulation acid and alkali-resistance coating that a kind of cost performance is higher.
Heat-absorbing paint is generally applied to the aspects such as solar absorber plate, solar energy collector.Solar energy heating flat board is, it comprises thick basic unit aluminium sheet, and described basic unit's surface of aluminum plate applies heat-absorbing paint layer is set, and it is the aluminium sheet of 1 series that described basic unit's aluminium sheet adopts the trade mark, good heat conductivity, is convenient to laser or ultrasonic welding.By apply one deck tool heat-absorbing paint layer in basic unit's surface of aluminum plate, make heat absorption flat plate.
Publication number is the preparation method that the Chinese patent of 103360803A discloses a kind of different poly-state sun power modified silicon solution selective heat-absorbing paint.It is by water glass, adds water to stir, and adds active silicic acid, makes silicon sol, then add 4 properties-correcting agent emulsions after insulated and stirred, is uniformly mixed to obtain film forming base-material; With film forming base-material and iron powder, grind to form uniform dispersion system, obtain heat-absorbing paint.Having solved current solar selectively absorbing coating, to prepare environmental pollution large, and cost is higher, and the bad technical problem of weathering resistance, but its preparation technology is more loaded down with trivial details, and heat absorption efficiency is low.
Publication number is that the Chinese patent of 103421367A discloses a kind of thermal insulation coatings, described thermal insulation coatings comprises following component (by weight percentage): material name, massfraction/%: silicon sol 12-15, photocuring prepolymer 4-8, water glass 10-20, polyoxyethylene enzyme 4-6, reflective dose of 2-4, water 30-40.Compared with prior art, the present invention has kept quick-drying and the easy brush property of organic coating, has reduced cost.But its heat insulation effect is lower, and paint stability is poor.
Meanwhile, a kind of coating can not reach two kinds of functions of heat insulation and heat absorption simultaneously.So the object of the invention is to prepare the integrated coating of a kind of heat insulation and heat absorption.
Summary of the invention
The present invention aims to provide the integrated coating of a kind of heat insulation and heat absorption, makes it have the function that absorbs sun power, has again incubation and thermal insulation function, and makes weathering resistance, temperature tolerance, the mechanical property of coating also better.Because glass fibre has incubation and thermal insulation function, Graphene has the function that absorbs infrared rapid intensification, therefore Graphene is plated on glass fibre, has insulation, heat absorption, intensification, energy-conservation function simultaneously.
The present invention is achieved through the following technical solutions: a kind of heat insulation and heat absorption integrative paint, is characterized in that by resin, functional agent, auxiliary agent and solvent composition.
Described heat insulation and heat absorption integrative paint, it is characterized in that by the acrylic acid modified resol of concentration 35%～60% be 35～40 parts, 1.2～2.6 parts, the glass fibre, the chromoxide green that are coated with Graphene be that 1.4～2.2 parts, 2.5～5 parts of dibutyl phthalates, silane coupling agent are that 0.3～0.6 part, 0.5%～1.5% polydimethylsiloxane are that 0.1 part, 1.7～2.3 parts of high-molecular type dispersing agents, acetone are that 7～8 parts, N-BUTYL ACETATE are that 8～10 parts, dimethylbenzene are 25～27 parts.
The described glass fibre that is coated with Graphene, glass diameter is 1～7 μ m, Graphene thickness is
staple length is 1mm～30mm.
The integrated coating of heat insulation and heat absorption, is characterized in that adopting the preparation method of following step:
1) modification of resol: phenol is mixed with formaldehyde, and then NaOH dilute solution, at 50 ℃ of reaction 2h, adds vinylformic acid, is warming up to 70 ℃ of reaction 1h, and water regulates the concentration of acrylic acid modified resol;
2) dilution of coupling agent: silane coupling agent is added in container, then adds above-mentioned solvent, stir standby;
3) pre-treatment of functional agent: the glass fibre that is coated with Graphene is joined in the container with agitating function, constantly stir, add gradually above-mentioned coupling agent, stir standby;
4) dispersion treatment: by above-mentioned formula macromolecule dispersing agent, dimethyl phthalate, polydimethylsiloxane, resin and pretreated functional agent high-speed mixing, be dispersed to below 30 μ m with ball mill, pour clean containers for future use into.
The present invention is through test of many times screening, acrylic acid modified resol, the glass fibre that is coated with Graphene, chromoxide green, dibutyl phthalate, silane coupling agent, polydimethylsiloxane, high-molecular type dispersing agent, acetone, N-BUTYL ACETATE and the dimethylbenzene of selected specified proportion.Its advantage is: (1) is coated with the glass fibre of Graphene by interpolation, makes coating have heat insulation and heat absorption function; (2) the coating erosion resistance, oil-proofness, the mechanical property that make are better.(3) the good and heat insulation and heat absorption function of the present invention makes coating weathering resistance, tint retention, is specially adapted to the fields such as solar energy collector, greenhouse.
