Problems solved by technology

[0004] At present, ordinary paint is used for the protection of pots and utensils and other products that use metal, glass and ceramics as substrates, which cannot show changes in the temperature of the product surface in the environment. Higher temperatures may cause the paint on the product surface to fall off. Expose the product to the environment, causing severe corrosion and shortening the life of the product
On the other hand, in production, due to the high temperature of the product, it is difficult for workers to master the operation. Therefore, there is an urgent need on the market for a coating with good heat resistance, strong adhesion, and low cost for surface decoration and paint film that will automatically change color with temperature.

[0044] Preparation of reversible color pigments:

[0045] (1) Disperse vanadium pentoxide and lanthanum chromite in 0.8M oxalic acid aqueous solution according to the above weight parts, and stir and disperse at 55°C and 430rpm for 45min;

[0046] (2) Then the temperature of the system was lowered to 12°C, and the coupling agent (a mixture of equal amounts of acetylacetone and tetraisopropyl titanate) was added dropwise. After the addition was completed, the temperature was raised to 65°C at a rate of 2.5°C / min, and then Add nano silicon dioxide and niobium pentoxide, keep stirring for 2 hours;

[0047] (3) Then the system was heated to 118°C for 9 hours in vacuum, then calcined at 760°C for 4 hours in an air atmosphere, and finally crushed to nanoscale to obtain a reversible color-reversing pigment.

Abstract

The invention discloses a gradient color organic silicon nano composite material as well as a production process and application thereof, and relates to the technical field of functional high polymer materials. The composite material is prepared from the following raw materials in parts by weight: 45 to 60 parts of modified polyacrylate emulsion, 18 to 24 parts of aluminum silicate, 8 to 14 parts of reversible color-changing pigment, 2 to 4 parts of pigment additive, 16 to 22 parts of water, 1 to 4 parts of thickening agent, 0.8 to 3 parts of flatting agent, 0.8 to 2 parts of wetting agent, 0.5 to 2 parts of defoaming agent, 0.2 to 1.5 parts of dispersing agent and 0.5 to 1 part of coalescing agent. After a substrate material is coated with the gradient color composite material, the gradient color composite material has high thermochromic capacity, the high temperature resistance and the acid and alkali corrosion resistance of a coating are enhanced, the adhesive force is remarkably improved, and the hardness is higher; and meanwhile, the surface of the coating has certain self-cleaning capability, and the surface glossiness is enhanced.

Description

technical field [0001] The invention belongs to the technical field of functional polymer materials, and in particular relates to a gradient-color organosilicon nanocomposite material and its production process and application. Background technique [0002] Thermochromic coatings refer to coatings that display different colors at different temperatures, and this color change may be reversible or irreversible. Due to the limitations of the materials used in our common thermochromic paints, the general discoloration range is below 120°C or even lower. At higher temperatures, the thermochromic pigments in the thermochromic paint decompose and lose the thermochromic function. However, in our daily life, the temperature of the coating on many products is much higher than 120°C. How to indicate the temperature of commonly used heating elements such as electric irons, frying pans, frying pans, baking pans, etc. through the temperature-sensitive color-changing coating It has reache...
