Embodiment 1-3

[0031] Embodiment 1-3 is implemented according to the following steps:

Embodiment 1

[0033] The molten glass flows into 1 glass with a temperature of 985°C and 440 holes. # The primary glass fiber filaments formed by the alloy bushing plate flow into a temperature of 1010°C1 # The flame blowing furnace head is pulled by secondary melting at high speed under the action of high temperature and high pressure mixed gas to form glass microfibers with a knockdown degree of SR°49. At the same time, the same molten glass flows into 2 glass with a temperature of 975°C and 350 holes # The primary glass fiber filaments formed by the alloy bushing flow into the 2 # The flame blowing furnace head is drawn into glass microfibers with a knockdown degree of SR°34 by secondary melting under the action of high temperature and high pressure mixed gas. At the same time, the same molten glass flows into the 3 # The primary glass fiber filaments formed by alloy bushings flow into 3 at a temperature of 1015°C # The flame blowing furnace head is pulled by secondary melting at hig...

Abstract

The invention relates to a thermal insulation and soundproof glass microfiber cotton for aviation and a preparation method thereof. The glass microfiber cotton includes ultrafine glass fiber cotton, a modified single-component water-based resin, a coupling agent and a water-based color paste. The fine glass fiber cotton is composed of glass microfibers with three kinds of rapping degrees SR°49±1, SR°34±1 and SR°24±1, and the modified single-component water-based resin includes Class A and Class B, wherein, Class A is modified water-based phenolic resin, and Class B is modified water-based polyurethane resin. The mixed solution B obtained by uniformly mixing Class B modified one-component water-based resin and coupling agent, and Class A modified one-component water-based resin The mixed solution A evenly mixed with the water-based color paste, the mixed solution B and the mixed solution A are coated on the surface of the glass microfiber in two steps and formed into a glass microfiber cotton, which has good softness, strong hydrophobicity, and mechanical properties. High-strength, heat-insulating and sound-insulating glass microfiber wool for aviation use.

Description

technical field [0001] The invention relates to a heat-preserving and sound-insulating glass microfiber felt for aviation and a preparation method thereof, belonging to the technical field of glass microfiber composite materials. Background technique [0002] Aviation glass fiber cotton is widely used as thermal insulation and sound insulation materials inside aircraft cabins because of its light weight, Class A non-combustibility, chemical stability and excellent sound insulation performance. The successful test flight has accelerated the research and development of high-performance aviation thermal insulation and soundproof glass fiber cotton. However, due to the constraints of the existing glass fiber wool production technology and production equipment, the fiber pore structure and bonding system of the produced glass fiber wool for aviation are not uniform, and the heat and sound insulation properties are attenuated. Therefore, the purpose of the present invention is to...
