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.
