Abstract

The invention relates to a biological soluble fiber mat, a preparation method thereof and a vacuum insulated panel using the mat. The mat is a fiber mat containing biological soluble fibers including 85-100wt% of biological soluble fibers and 0-15wt% of cured adhesives. The biological soluble fibers penetrate through one another and intertwine or are in overlapping joint in the form of single filaments or distributed in an interwoven mode. Few biological soluble fibers extend close to the thickness direction of the mat. The adhesives are dispersed among signal filaments, closely adhered to one another and do not independently exist. The average fiber diameter of a biological soluble fibers is less than or equal to 30 [mu]m and the average fiber length is less than or equal to 250 mm. Harm of fiber dust generated during manufacture and usage of the fiber mat to human bodies can be effectively avoided.

Description

technical field [0001] The invention relates to a thermal insulation material, a preparation method thereof and a thermal insulation product using the thermal insulation material. Background technique [0002] Vacuum insulation panel (English full name VacuumInsulationPanel, hereinafter referred to as VIP) is mainly composed of core material (hereinafter referred to as core material), barrier bag and getter, and its structure is as follows: figure 1 and Picture 1-1 shown. The barrier bag 11 is mainly a packaging bag composed of a polymer film and a special coating film or aluminum foil. Edge banding 10. The core material 12 is the core of the VIP, which is formed by stacking multi-layer felts 121, which play the role of skeleton support, reduce heat transfer and facilitate degassing; the getter 13 is mainly calcium oxide type getter or alloy type The getter or calcium oxide and alloy getter is an important part of VIP, which absorbs the residual gas (including water vap...
