Problems solved by technology

However, the current building energy-saving and thermal insulation measures are only aimed at the outer envelope of the building. Generally, no thermal insulation measures are used between the partition walls of the buildings in the building. In this way, different buildings may have different temperatures, resulting in thermal pressure. A room experiences heat loss, the flow of hea

preparation example Construction

[0048] The present invention has no special restrictions on the preparation method of the inner wall insulation coating, and the preparation method of the inner wall coating well known to those skilled in the art may be used. In the present invention, the internal wall insulation coating is preferably prepared according to the following method:

[0049] Mix water, additives and inorganic fillers to obtain a mixture;

[0050] Superfine the mixture to obtain superfine particles;

[0051] Mixing the ultra-fine particles with metal-coated hollow microbeads to obtain a slurry;

[0052] The slurry is mixed with the coating resin to obtain the internal wall insulation coating.

[0053] The present invention first mixes water, additives and inorganic fillers to obtain a mixture. In the present invention, there is no special restriction on the order of adding the water, auxiliary agent and inorganic filler when mixing, and the order of adding is well known to those skilled in the art. In the ...

Embodiment 1

[0111] Put 5g of TiO with a particle size of 5μm 2 Add 200mL of distilled water to make a slurry, add 0.1g of sodium hexametaphosphate and stir to make TiO 2 Fully dispersed; then 1g Na 2 CO 3 Dissolve 2.5g of direct light fast turquoise blue GL in 85℃~90℃ hot water, add the obtained color pigment solution to the above slurry after proper stirring, adjust the pH of the reaction solution and keep it constant, and perform constant temperature coloring for 2.5h ; Will BaCl 2 Dissolve in hot water at 80℃, add it to the colored solution in 5 times, and then add OP emulsifier and fixing agent Y diluted with water in sequence; after stirring and mixing for 3 hours, wash, filter, and After drying, a colored infrared reflective pigment is obtained.

Embodiment 2

[0113] In parts by weight, add 22 parts of water to the batching tank, add 1 part of sodium polyphosphate, 2 parts of alcohol ester twelve, 1 part of silicone defoamer, 1 part of propylene glycol and 1 part of cellulose ether to thicken After mixing uniformly, add 22 parts of ordinary titanium dioxide with a particle size of 1μm to the mixture, and disperse the obtained mixture at a speed of 100 rpm; then, the dispersed mixture is ultra-fine under the strong shear of a high-speed disperser ; Add 20 parts of rutile titanium dioxide with a particle size of 6μm to the ultra-fine mixture and disperse it evenly; then add 30 parts of acrylate emulsion to disperse to obtain the base paint;

Abstract

The invention provides interior wall heat-insulating paint which comprises the following components in parts by weight: 5-45 parts of water, 3-25 parts of assistant, 3-55 parts of inorganic filler, 5-55 parts of paint resin and 1-30 parts of metal-coated hollow microsphere. The interior wall heat-insulating material provided by the invention comprises the metal-coated hollow microsphere, so that the metal-coated hollow microsphere ensures that the infrared reflectivity is improved, the emissivity is reduced, and certain heat reflection effect is achieved; and the metal-coated hollow microsphere is in a hollow structure and is low in heat conductivity coefficient, so that no convected air exists in the prepared interior wall heat-insulating paint, the heat conductivity coefficient of the paint is reduced, and the middle and far infrared heat ray blocking capability of a heat-insulating coating is greatly enhanced, thereby improving the indoor heat-insulating effect. Experimental results indicate that the interior wall heat-insulating paint provided by the invention can increase the indoor temperature by 2-3 DEG C.

Description

Technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an internal wall thermal insulation coating. Background technique [0002] At present, the heating methods commonly used in my country are mainly radiator convective heating modes, such as floor heating, radiators, etc. Radiant heating systems such as infrared electric heating film are gradually popularizing because of the more even heat distribution and higher heat effect on the human body and other objects. The indoor heat conduction methods are mainly radiation and convection. Regardless of whether convection heating or radiant heating is used, heat radiation plays an important role in indoor heat. When heat radiation reaches the wall surface, it will be absorbed by the wall and lost to the outdoors. [0003] Heating energy consumption in winter is the main energy consumption of Chinese buildings, and the Chinese government's requirements for building energy savi...
