Glass fiber blanket and producing method thereof

Abstract

The invention discloses a glass fiber blanket and a producing method thereof. The method comprises the steps of mixing the following components , by mass, 35-40 parts of silica flour, 5-12 parts of feldspar, 9-14 parts of borax, 1-3.5 parts of calcite, 6-8 parts of dolomite, 11-14 parts of soda ash, and 15-25 parts of sheet glass to form a mixture; melting the mixture to obtain glass metal; placing the glass metal in a centrifugal machine for spinning treatment to obtain glass fiber and spraying water and binders onto the surface of the glass fiber in a vaporific mode at the same time; placing the glass fiber coated with the binders in a cotton collecting machine to enable the glass fiber to evenly fall onto the cotton collecting machine under the action of a negative-pressure fan to form a glass cotton layer; and conveying the glass cotton layer well laid to a curing oven through a conveyer to be cured to obtain the glass fiber blanket.

Description

technical field [0001] The embodiment of the invention relates to a glass fiber felt and a production method thereof. Background technique [0002] The existing glass fiber felt has a relatively high density (generally 10kg / m 3 Above), the fiber diameter is relatively thick (generally 5 microns), the thickness is above 40mm, and the uniformity of diameter and thickness is low, the surface density is uneven, the softness is poor, the fiber distribution of cotton felt is uneven, and the strength performance of the product, The combustion performance and sound-absorbing performance are not ideal. The bonding fastness of the existing glass fiber mat cannot meet the requirements. It is easy to crack the insulation material and the material to be insulated in places where it is used for aviation and other severe vibrations. Therefore, the existing glass fiber mat Fiber cotton felt can hardly be used in high-end fields such as aviation, nuclear power, and submarines. Contents of...
