Abstract

The invention discloses a vacuum insulated panel core material, which comprises the following raw materials in parts by weight: 48 parts of mineral wool, 45 parts of glass fiber wool 27-30 degree SR and 35 parts of glass fiber wool 18 degree SR. The diameter of the fiber of the mineral wool is 4-6 mum, the length is 1.0-4.0mm and the water content is 20 percent. The manufacturing method of the vacuum insulated panel core material comprises the following steps: pumping of glass fiber wool, pulping of mineral wool, dilution and slag removal, regulation of acidity, slag removal and making, drying and cutting. Since the mineral wool is used, the manufacturing cost of the core material is greatly reduced and the insulation performance is improved to certain extent when the vacuum insulated panel core material is compared with pure glass fiber wool core material and other conventional core material.

Description

technical field

[0001] The invention relates to a heat insulating material and a manufacturing method thereof, in particular to a vacuum heat insulating panel core material and a manufacturing method thereof. Background technique

[0002] Vacuum insulation panels are widely used in refrigeration equipment such as refrigerators and freezers. They are placed in the interlayer of the outer wall of the equipment to reduce heat loss and energy consumption. The insulation performance of vacuum insulation panels mainly depends on the thermal conductivity of its core material. .

[0003] At present, the commonly used vacuum insulation panels mainly use polymerized organic fibers, centrifugal cotton and glass fiber cotton, glass fibers sprayed with organic binders, etc. as core materials, and polymerized organic fiber core materials, centrifugal cotton and glass fiber cotton core materials The manufacturing cost is low, but its thermal insulation performance cannot achieve the ideal...
