Title:
THERMAL INSULATION COMPOSITE SHEET AND MANUFACTURING APPARATUS OR MANUFACTURING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2017051114
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermal insulation composite sheet which is used for a roof and an outside wall of an agricultural or horticultural vinyl house and green house to save on energy and reduce cost and by which abnormal temperature rise in the green house during summer and unusual low temperature during winter or in a cold district is suppressed so as to give optimal grow environment to cultivation vegetable, fruit and the like.SOLUTION: A thermal insulation composite sheet 1 includes a thermal insulation air chamber part 4 which is formed by partitioning a space between a pair of clear films 2a, 2b in one direction of a flat surface by partition parts 3 made from light shielding resin to have a plurality of cylindrical parts. The partition part 3 is formed to be in a vertical direction or in a diagonal direction between the clear films 2a, 2b so as to control quantity of light entering into the partition part. The thermal insulation composite sheet includes line-shaped heat bonding parts 5 having a prescribed width parallel to each other at a definite interval in a direction vertical to the one direction of the flat surface between the clear films 2a, 2b. At least one of a nonwoven fabric 6, a net material 7, and a light-incident angle control sheet 8 is stuck to the clear film 2a (2b).SELECTED DRAWING: Figure 1
