The invention provides a core material for a dry-method vacuum insulation panel and a preparation method thereof. The core material for the dry-method vacuum insulation panel comprises glass fibers and an adhesive, wherein the solid content of the adhesive is 0.3-2% of the mass of the glass fibers. The preparation method comprises the following steps of firstly, fully mixing the adhesive with water according to a weight ratio of 1:(3-20), and then carrying out atomizing; secondly, in the process of centrifugally spraying the glass fibers by adopting a centrifugal machine, mixing and adding themixture of the atomized adhesive and water, wherein the mixing ratio is that the solid content of the adhesive is 0.3-2% of the mass of the glass fibers; and finally, drying, curing and hot-pressingthe glass fibers mixed with the adhesive to form the core material for a vacuum insulation panel, wherein the density of the hot-pressed core material is 60-200 Kg/m<3>. According to the core materialfor the dry-method vacuum insulation panel and the preparation method thereof, reasonable proportioning and continuous production process control are adopted, so that the quality uniformity of the core material is greatly improved, there are no slag balls, and the heat insulation performance is good.
本发明提供一种干法真空绝热板用芯材及其制备方法。所述干法真空绝热板用芯材包括玻璃纤维及粘合剂，所述粘合剂的固含量为所述玻璃纤维质量的0.3%‑2%。其制备方法为：首先将粘合剂与水按照重量比为1：（3‑20）的比例充分混合后雾化；再将玻璃纤维采用离心机离心喷射的过程中，混合加入雾化后的粘合剂与水的混合物，混合比例为粘合剂的固含量为所述玻璃纤维质量的0.3%‑2%；最后将混合粘合剂的玻璃纤维进行烘干固化并热压成真空绝热板用芯材，热压到芯材的密度为60‑200Kg/m3。本发明采用合理的配比和连续的生产工艺控制，使得芯材质量均匀度大大提高，且无渣球，绝热性能好。
