Abstract
The invention discloses a paint containing heat-insulating anti-corrosion composite functional pigment, which consists of the following components: 20-40 parts of color compound, 20-100 parts of solvent, 0.05-3 parts of dispersing agent and 10-40 parts of resin. The color compound comprises one of red, yellow and blue color compounds, and is obtained by grinding and calcining an inorganic precursor material and coupling and modifying an organic pigment. The invention combines the high weather resistance of the inorganic heat insulation material with the bright color of the organic pigment, so that the finished product raw material has high performance of no deterioration, no fading and no failure in long-term outdoor service, overcomes the difficult problem that the traditional pigment is difficult to realize weather resistance and high saturated color, and is especially suitable for the infrared reflection heat insulation field of urban buildings.
Description
Technical Field
The invention relates to the technical field of functional coatings, in particular to a preparation method and application of a coating containing heat-insulating anti-corrosion composite functional pigment.
Background
The pigment has wide application in the fields of varnish, paint, plastic, printing ink, printing and dyeing, rubber and the like. The organic pigment has rich and bright color and poor weather resistance; the inorganic pigment has the characteristics of stronger environmental friendliness, acid and alkali resistance, fire resistance and the like although the color is dull.
The inorganic pigment with infrared reflection performance can be also used for energy-saving exterior packaging of areas such as roofs, outer walls and the like in the building field, so that the heat island effect of urban buildings caused by heat radiation is relieved, and heating and cooling energy consumption increased by temperature rise in the buildings is reduced. At present, the inorganic pigments with high infrared reflection efficiency are titanium oxide and zinc oxide, the near infrared reflectivity is as high as 80%, but the color is too white, and light pollution is easy to cause. In addition, the colored energy-saving exterior pigment has wider application prospect due to other requirements such as attractive appearance.
Patent CN 114292536A provides an inorganic coating with reflective insulation function, which solves the problems of dispersion of reflective insulation pigment, hollow glass beads and system compatibility, and the problems of no post-thickening and stable color of the inorganic insulation coating, but the inorganic pigment itself has the advantage of stable color, and the problem of insufficient vividness of the inorganic pigment is not solved. Patent CN 106436377B discloses a reconnaissance camouflage functional inorganic pigment, an inorganic printing paint and a fabric, and an infrared reflecting material uses titanium chrome yellow, titanium manganese brown, cobalt blue, titanium cobalt green, titanium nickel yellow, copper chrome black and iron chrome black, so that the environmental pollution problem caused by cloth printing and dyeing is solved, the technical problems of ageing, color change and short service life of coating printing are easily caused, but the problem of dark color of the inorganic pigment is not solved, and when the inorganic pigment is used as a heat insulation paint, corrosion phenomenon is easily caused under the environmental influence of long-term exposure. Therefore, a new solution is needed.
Disclosure of Invention
The invention aims to provide a paint containing a heat-insulating corrosion-resistant composite functional pigment, which solves the problem that inorganic pigment is dull in color and is easy to generate corrosion phenomenon under the influence of environment exposed for a long time when the paint is used as a heat-insulating paint.
In order to achieve the above purpose, the present invention provides the following technical solutions: a paint containing heat-insulating and corrosion-preventing composite functional pigment consists of the following components in parts by mass: 20-40 parts of color compound, 20-100 parts of solvent, 0.05-3 parts of dispersing agent and 10-40 parts of resin; the color compound is one or more of red color compound, yellow color compound and blue color compound; the solvent is one or more selected from ethanol, isopropanol, butanol, isobutanol, amyl alcohol, ethyl acetate, butyl acetate, methyl isobutyl ketone and ethylene glycol methyl ether acetate; the dispersing agent is one or more selected from polyvinylpyrrolidone and polyethylene glycol; the resin is one or more selected from acrylic resin, organic silicon resin and polyester resin;
the preparation method of the color compound comprises the following steps:
step 1: weighing a precursor material with a stoichiometric formula, grinding the precursor material with a medium, specifically, wet-grinding the weighed precursor material with the medium, wherein the medium accounts for 50-150wt% of the total weight of the precursor material, grinding the precursor material until the medium volatilizes, and repeating the process for 2-5 times;
