Abstract

The invention discloses a preparation method of glass wool. The method comprises the following steps of: producing glass wool filaments by adopting a centrifugal blowing method, uniformly atomizing glass wool adhesive onto the surface of the glass wool filaments, collecting wool of the glass wool fibers by virtue of a wool collection machine, transporting to a curing furnace, and performing the curing at the temperature of 220 to 270 DEG C, wherein the weight ratio of the glass wool filaments to the glass wool adhesive is (4 to 6): (94 to 96). The invention aims at providing glass wool and a preparation method of the glass wool. The glass wool has high strength and good thermal insulating performance.

Description

technical field [0001] The invention relates to the field of glass wool, in particular to glass wool and a preparation method thereof. Background technique [0002] Glass wool belongs to a category of glass fibers and is a man-made inorganic fiber. Glass wool is a material made of molten glass fibrosis to form a cotton-like material. Its chemical composition belongs to glass and is an inorganic fiber. It has good molding, low bulk density, low thermal conductivity, thermal insulation, good sound absorption performance, and corrosion resistance. , The advantages of stable chemical properties. [0003] The disadvantage of commercially available glass wool is that its strength and thermal insulation performance need to be further improved. Contents of the invention [0004] The object of the present invention is to provide a kind of glass wool and its preparation method, the glass wool has good strength and heat insulation performance. [0005] The technical scheme of the ...
