Abstract
The invention relates to an aqueous one-component solar energy adsorption coating, in particular to an improvement of coating production technology; the raw materials and the proportioning range are that by weight ratio: 50-60 of acrylic resin modified polyorganosiloxane emulsion, 20-30 of deionized water, 20-25 of PbS or FeMnCuO4 and 5-10 of multi-functional-group polymeric alkyl ammonium salt solution; the aqueous one-component solar energy adsorption coating has the beneficial effects that: 1. the coating has the characteristics of noninflammability, no environment pollution and energy saving; 2. the coating has good adhesive force to bottom material, and has good shock resistance, bending resistance and humidity resistance; 3. the coating has good aging resistance and salt fog resistance; 4. the solar energy absorptivity of the coating is high.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of improvement of coating material production technology.
Background technology
Sun power is topmost energy source on the earth, has many advantages that traditional energy hardly matches.The sun is invested the total radiation energy on ground up to 6 * 10
9KW is equivalent to more than 50,000 times of present world gross generation, and inexhaustible, and it is a kind of clean energy again, and is free from environmental pollution.But sun power one is that energy disperses, the energy density of unit surface is low; The 2nd, sun power receives round the clock, season and climatic influences are very big; Make the utilization of sun power run into all difficulties.
The key of sun power utilization is to gather to greatest extent the radiating capacity of the sun.From technology and economic point of view, comparatively practicable at no distant date approach is to be solar energy converting that heat energy is used.The parts that achieve this end are exactly so-called solar energy collector, though heat collector can have various forms or structure, wherein the part of most critical is the functional coating with photo-thermal conversion---and sun power is selected absorber coatings.
At present, different according to absorber coatings preparation technology, can be divided into: chemical vapor deposited coatings (CND), vacuum evaporation coating, radio-frequency sputtering coating, application type coating etc.Though technologies such as CND, vacuum evaporation, radio-frequency sputtering can have been prepared the good lighting material of spectral selectivity and since have complex process, cost expensive, to shortcomings such as ground are strict, large-scale promotion application is restricted.
Summary of the invention
The objective of the invention is: a kind of aqueous one-component solar energy adsorption coating is provided, and it can convert the radiation luminous energy of gathering the sun to heat energy.
Raw material of the present invention and ratio range are:
Vinyl resin modified polyorganosiloxane emulsion is 50-60
Deionized water is 20-30
PbS or FeMnCuO
4Be 20-25
The alkylammonium salt solution of polyfunctional group polymkeric substance is 5-10;
Above-mentioned raw materials is weight ratio.
Production technique of the present invention is:
With vinyl resin modified polyorganosiloxane emulsion, PbS or FeMnCuO
4, deionized water, polyfunctional group polymkeric substance alkylammonium salt solution in charging tank, stir, feed intake in order feeds intake 10 minutes at interval at every turn, all feeds intake to finish restir and stop after 30-40 minute stirring.
Mixed fully after, mixed paint liquid is sent into shredder, begin to grind, when being ground to fineness and being 5 μ m (the fineness scraper plate is surveyed fineness), will coat with lacquer in the liquid importing paint mixing tank.
Filter with 200 order silks.
The invention has the beneficial effects as follows: 1. this product have do not fire, free from environmental pollution, save characteristics such as the energy.2. ground is had good sticking power, the shock-resistance of filming, resistance to bend(ing), humidity resistance are good.3. this product has good stability to aging and salt fog resistance.The solar absorptance of 4. filming is high.
