example 1

[0044] Especially preferred formulations for reflection of all IR rays in the near IR range through gypsum paperboard, the composition of which is as follows:

[0045] 10.5% hollow glass spheres with a diameter of 1 to 90 µm;

[0046] 12% silver-coated hollow glass spheres with a diameter of 10 to 90 µm;

[0047] 5.5% silver-plated hollow glass sphere

[0048] 13.8% mica

[0049] 0.5% dispersant (Ciba)

[0050] 0.5 % Dehydran 1620 (Cognis)

[0051] 0.5 % Propylene carbonate (Merck)

[0052] 0.2 % Walocel MKX 20000 PF 40 (Wolf Cellul. AG)

[0053] 0.5 % Wallatrop S (Osthoff-Petrasch GmbH)

[0054] 14.5% Mowelith 1871

[0055] 20% titanium dioxide

[0056] 21.5% filler such as calcium carbonate with a gradation curve from 10 to 4000 µm

example 2

[0058] Preference is given to compositions with good reflective properties for A in the range 780 to 1400 nm and B in the range 1400 to 3000 nm infrared radiation:

[0059] a) Recipe 1 :

[0060] 12.5% ​​hollow glass spheres with a diameter of 0.5 to 50 µm;

[0061] 7.5% aluminized hollow glass sphere;

[0062] 25% solid glass spheres with a diameter of 0.5 to 70 µm;

[0063] 3.5% silver-plated solid glass ball;

[0064] 7.5% aluminized solid glass ball;

[0065] 1.25% silver-plated hollow glass ball;

[0066] 42.75% filler (mica with a diameter of 0.5 to 200 µm).

[0067] When irradiated with infrared light in the wavelength ranges A, B and C, 91.5% of the infrared rays in the wavelength ranges A and B will be reflected.

[0068] b) Recipe 2 :

[0069] 8.5% hollow glass spheres with a diameter of 0.5 to 170 µm;

[0070] 12% aluminized hollow glass ball;

[0071] 5% silver-plated hollow glass ball;

[0072] 35% solid glass spheres with a diameter of 0.5 to 150 µm...

example 3

[0079] Another IR reflective component that may be suitable for use in the coating is a combination of Formulation 1 and Formulation 2 with a higher ratio of 3 to 1 in Formulation 1.

Abstract

The invention relates to an IR-reflecting composition including a mixture of glass components selected from the group comprising hollow glass beads, solid glass beads, silver-coated hollow glass beads, silver-coated solid glass beads, aluminium-coated hollow glass beads and aluminium-coated solid glass beads. The invention further provides building materials having a coating comprising the IR-reflecting composition.

Description

technical field [0001] The present invention relates to an infrared reflective composition. In addition, the subject matter of the present invention also includes building materials comprising a coating of an infrared reflective composition. Background technique [0002] As early as 3,000 years ago, the Chinese have learned that thermal radiation to the human body can have a positive therapeutic effect. In the past 20 years, studies have found that infrared radiation in the similar infrared range (infrared A 780 nm to 1400 nm and infrared B 1400 nm to 3000 nm) is more easily absorbed by the human body. If the ray is applied indoors, there will be an ideal body temperature, which is beneficial to health, can improve concentration, and can promote mental perception, which is beneficial to mental relaxation. [0003] Infrared radiation has a wide range of medical effects. Its indications include acute and chronic muscle pain, muscle and joint stiffness of various causes (exc...
