preparation example Construction

[0024] The embodiment of the present invention also provides a preparation method of the above-mentioned dopant, comprising the following steps:

[0025] Step S1: dissolving the organic N-type dopant with an organic solvent to obtain an organic N-type dopant solution.

[0026] In the embodiment of the present invention, the specific use type and amount of the organic solvent have little effect on the performance of the obtained dopant, so no specific limitations are made here. For example, the type of use can be ethanol, and the amount can be 0.1 mg of organic N-type Dopants were dissolved in 1 mL of organic solvent as standard.

[0027] Step S2: uniformly mixing the organic N-type doping solution and the polyelectrolyte complex to obtain.

[0028] The embodiment of the present invention also provides an application of the above-mentioned dopant in improving the temperature monitoring sensitivity of latex paint.

[0029] The embodiment of the present invention also provides ...

Embodiment 1

[0035] Weigh 0.1mg dimethylthiomethylbenzene Dissolve in 1 mL of ethanol, accurately pipette 0.2 mL into 0.62 g of PEDOT:PSS solution with a pipette gun, and stir well with a glass rod to obtain dopant 1.

[0036] Weigh 1g of water-based latex paint into a 25mL beaker, add the obtained dopant 1 into the beaker, stir well with a glass rod, and after the dopant 1 is completely mixed with the latex paint, heat and stir by collecting heat Properly heat the container at 80°C for 8 minutes. During the heating period, use a stirring rod to stir evenly to prevent the sample from being grainy due to uneven heating during the heating process. After heating, an off-white suspension is obtained, which is the functional latex paint.

Embodiment 2

[0038] Weigh 0.1mg triphenylmethane derivative Dissolve in 1 mL of ethanol, accurately pipette 0.2 mL into 0.62 g of PEDOT:PSS solution with a pipette gun, and stir well with a glass rod to obtain dopant 2.

[0039] Weigh 1g of water-based latex paint into a 25mL beaker, add the obtained dopant 2 into the beaker, stir well with a glass rod, and after the dopant 2 is completely mixed with the latex paint, heat and stir by collecting heat Properly heat the container at 80°C for 8 minutes. During the heating period, use a stirring rod to stir evenly to prevent the sample from being grainy due to uneven heating during the heating process. After heating, an off-white suspension is obtained, which is the functional latex paint.

Abstract

The invention is suitable for the technical field of building materials, and provides a dopant and a preparation method and application thereof, and a functional latex paint. The dopant is formed by compounding an organic N-type dopant and a polyelectrolyte compound, and the mass ratio of the organic N-type dopant is 0.001%-20% of the mass of the polyelectrolyte compound. After the dopant is doped into and mixed with common water-based latex paint, the temperature change detection sensitivity of the latex paint can be greatly improved, the latex paint is very sensitive to the temperature change in the temperature interval of 25-90 DEG C, meanwhile, the thickness of an obtained doped latex paint film can reach 1000 microns or above, and the latex paint can be used for monitoring the temperature of a daily living house and can be applied to future smart home as a building material.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a dopant, its preparation method, application and functional latex paint. Background technique [0002] With the advancement of science and technology and the improvement of material level, smart home has gradually entered people's lives. Compared with traditional solvent-based paints, water-based latex paints have the characteristics of low formaldehyde and low aromatic hydrocarbons, making them more popular in the use of building materials. [0003] However, the decoration and simple protective effect of traditional latex paint can no longer meet the development of modern industry. It is required not only to have decorative or protective effect, but also to have one or more other functions, such as heat insulation, high Special medium corrosion, self-cleaning, high insulation, high wear resistance, fire resistance, etc. Therefore, functional latex paint ...
