Embodiment 1

[0075] Mixture of perfluoroisopropyl ether oil, medium and low viscosity alkoxy-terminated methyl silicone oil and methyl hydrogen silicone oil (ratio: 1:1:1) 5 parts

[0076] Steps:

[0077] 1. A. The transition metal alcohol M(OR)n salt is isopropyl titanate [Ti(OPr) 4 ], isopropyl vanadate [V(OPr) 4 ], cerium ethylate [Ce(OEt) 4 ], tungsten hexaethoxide [W(OEt) 6 ] and so on were dissolved in absolute ethanol, and then AcAc was added in a metered amount to make a complex solution. B. Nitrates are soluble in ethanol or water. C. Dissolve aluminum isopropoxide in absolute ethanol. D. Add ethyl orthosilicate [Si(OEt) 4 ] and other components were refluxed under nitrogen for 1-5h.

[0078] 2. After hydrolysis and condensation, the catalyst is filtered out, the filtrate is evaporated to remove the solvent, and the water is taken out, and 1-5% of water-removing agent and 0.2-3% of tin-titanium composite curing catalyst (Sn / Ti=1-1.5) are added.

Embodiment 2

[0082] A mixture of perfluoroisopropyl ether oil, medium and low viscosity alkoxy-terminated methyl silicone oil and methyl hydrogen silicone oil (ratio 1:1:1) 5 parts of which:

[0083] 1. A. Dissolve the transition metal alkoxide in absolute ethanol, and then add AcAc according to the metered amount to make a complex solution. B. Nitrates are soluble in ethanol or water. C. Dissolve aluminum isopropoxide in absolute ethanol. D. Adding prefabricated functional colloidal tetraethyl orthosilicate [Si(OEt) 4 ] and other components were refluxed under nitrogen for 3h.

[0084] 2. After hydrolysis and condensation, the catalyst is filtered out, the filtrate is evaporated to remove the solvent, and the water is taken out, then anhydrous solvent is added to dilute to 10-30%, and water remover is added to 1-5%, tin-titanium composite curing catalyst (Sn / Ti =1-1.5), 0.2-3%.

Abstract

The present invention relates to an intelligent paint film material and the preparation method thereof, which mainly realizes sol one-step method to prepare the sol pre-polymerization product with multi-component and multifunctional structure, which is solidified at room temperature and then forms the nanostructure intelligent paint film material. The preparation method is that: metal alkoxide and transition metal coordinated complex are refluxed, hydrolyzed and co-condensed in anhydrous alcohol solvent; or the metal alkoxide and transition metal coordinated complex are hydrolyzed and co-condensed with inorganic metallic salt; or the above composition is refluxed, hydrolyzed and co-condensed with functional sol prepared in advance under the above conditions, producing the sol which is added with stabilizer to prepare a standby product. The product has the functions of photocatalysis intelligent perceiving, self cleaning, air purifying, heat shielding and natural temperature adjusting functions, which can be widely applied to construction industry after the product is solidified and forms film at normal temperature.

Description

technical field [0001] The invention belongs to intelligent coating material and co-production technology. Background technique [0002] Reports on smart coatings have been reported since June 2006. The University of Newcastle in the UK realizes the piezoelectric function by adding pressure-sensitive ceramic grain lead zirconate titanate to the coating. It is a coating used to monitor the fatigue degree of building materials. Materials, that is, coatings that are stimulated by external forces such as stretching, extrusion, and knocking to generate electrical signals. Then it was reported that the European Union multinational cooperation developed a nano-TiO 2 Exterior paints for absorbing air pollutants, purported to absorb NO x up to 85%. Then the United States also made a positive response. The American Industrial Nano Corporation announced that it would set up a research and development institution specializing in smart coatings. Regarding high-strength materials, it ...
