Problems solved by technology

On the surface of water supply and drainage pipes, building walls, air-conditioning equipment, and radiant refrigeration terminals, when the air reaches a certain humidity and the part in contact with the moist air cools to a temperature lower than the saturation temperature of the moist air, the air contained in the air near the interface The water vapor will condense into water and turn into water droplets, and condensation will appear. If this condensation lasts for a long time, it will cause equipment damage, product mildew or rust and other adverse effects, and serious accidents will cause vicious safety accidents.
[0003] At present, most buildings are made of glass, wood products, paper products, gypsum and other materials, which have poor water absorption performance.

Embodiment 1

[0023] This example provides a method for preparing an anti-condensation paint. The components of the anti-condensation paint are: 150 parts of water, 30 parts of zeolite, 105 parts of shell powder, and 15 parts of MIL-100 (Fe).

[0024] The preparation method of this anti-condensation coating:

[0025] (1) The first stage: add water and MIL-100(Fe) into a 500ml reactor according to the mass ratio and stir for 5 minutes, then put the reactor into an ultrasonic cleaner and vibrate ultrasonically for 20 minutes to make the MIL-100(Fe) ) are evenly dispersed.

[0026] (2) The second stage: Add shell powder and zeolite to the reactor in sequence according to the mass ratio, and use an electric stirrer to stir at a constant speed of 800-1000 rpm for 20-30 minutes to form a uniform mixture.

[0027] The anti-condensation coating has a moisture absorption of 21.7g / m when the thickness is 2mm and the relative humidity is 70%. 2 .

Embodiment 2

[0029] This example provides a method for preparing an anti-condensation coating. The components of the anti-condensation coating are: 150 parts of water, 30 parts of zeolite, 112.5 parts of diatomaceous earth, and 7.5 parts of MIL-100 (Fe). .

[0030] (1) The first stage: add water and MIL-100(Fe) into a 500ml reactor according to the mass ratio and stir for 5 minutes, then put the reactor into an ultrasonic cleaner and vibrate ultrasonically for 20 minutes to make the MIL-100(Fe) ) are evenly dispersed.

[0031] (2) The second stage: add diatomaceous earth and zeolite to the reactor in sequence according to the mass ratio, and use an electric stirrer to stir at a constant speed of 800-1000 rpm for 20-30 minutes to form a uniform mixture.

[0032] The anti-condensation coating, when the thickness is 2mm, under the condition of relative humidity of 70%, the moisture absorption is 29.3g / m 2 .

Embodiment 3

[0034] This example provides a method for preparing an anti-condensation coating. The components of the anti-condensation coating are: 150 parts of water, 30 parts of zeolite, 105 parts of diatomaceous earth, and 15 parts of MIL-100 (Fe). .

[0035] The preparation method of this anti-condensation coating:

[0036] (1) The first stage: add water and MIL-100(Fe) into a 500ml reactor according to the mass ratio and stir for 5 minutes, then put the reactor into an ultrasonic cleaner and vibrate ultrasonically for 20 minutes to make the MIL-100(Fe) ) are evenly dispersed.

[0037] (2) The second stage: add diatomaceous earth and zeolite to the reactor in sequence according to the mass ratio, and use an electric stirrer to stir at a constant speed of 800-1000 rpm for 20-30 minutes to form a uniform mixture.

[0038] The anti-condensation coating has a moisture absorption of 32.6g / m when the thickness is 2mm and the relative humidity is 70%. 2 .

Abstract

The invention relates to an anti-condensation coating as well as a preparation method and application thereof. The anti-condensation coating comprises the following components in parts by mass: 120-180 parts of water, 120-142.5 parts of a humidity control material and 7.5-30 parts of a metal organic framework. The preparation method comprises the following steps: adding water and a metal organic framework into a reactor according to a mass ratio, stirring for 1-10 minutes, then carrying out ultrasonic oscillation for 15-30 minutes, and uniformly dispersing the metal organic framework; the humidity adjusting materials are sequentially added into the reactor according to the mass proportion, stirring is conducted for 20-30 min at the constant rotating speed of 800-1000 r / min, and a uniform mixture is formed and can be used for the inner surface of a building and the like. Compared with the prior art, the product obtained by the invention has the characteristics of high water absorption capacity, high water absorption speed and volatilization speed and long service life, and has the functions of heat insulation, mildew prevention, condensation prevention and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an anti-condensation coating and its preparation method and application. Background technique [0002] Condensation refers to the phenomenon that when the water vapor in the air reaches saturation, if the surface temperature of the object is lower than the dew point temperature of the nearby air, condensation water will appear on the surface. On the surface of water supply and drainage pipes, building walls, air-conditioning equipment, and radiant refrigeration terminals, when the air reaches a certain humidity and the part in contact with the moist air cools to a temperature lower than the saturation temperature of the moist air, the air contained in the air near the interface The water vapor will condense into water and become water droplets, and condensation will appear. If this condensation lasts for a long time, it will cause equipment damage, product m...
