Title:
HEAT INSULATING FILM MATERIAL EXCELLENT IN DAYLIGHTING PROPERTY
Document Type and Number:
Japanese Patent JP2015100942
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a flexible membrane material scattering light in a near infrared region, especially excellent in heat insulation to solar radiation, excellent in daylighting by transmission of light in a visible light region and capable of coloring.SOLUTION: There is provided a heat insulation membrane material which is a flexible sheet 1 having at least a layer of a near infrared ray shielding layer 2, which contains a matrix resin consisting of a soft vinyl chloride resin composition and, as a heat insulator 3, titanium oxide particle 3-1 having an average particle diameter of 0.5 to 2.0 μm and barium sulfate particle 3-2 having the average particle diameter of 0.3 to 1.2 μm dispersed in the matrix resin at 5 to 25 mass% where a mass ratio of the titanium oxide particle and the barium sulfate particle is 1:1 to 1:5 in the heat insulator 3 and the titanium oxide particle and the barium sulfate particle are surface coated by one or more of an inorganic material selected from silica, alumina, zirconium oxide or the like and a coupling agent selected from silane-based, titanate-based or the like.
