Embodiment 1-3

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

Embodiment 1

[0033] The inflow temperature of the glass liquid is 1015°C and the hole diameter is 17mm. # The molten glass stream formed by the alloy bushing flows into a temperature of 995 ℃, the number of holes is 17500, and the rotation speed is 3700rpm. # Centrifugal disc, and relying on the centrifugal force of high-speed rotating centrifugal disc and the action of high-pressure extension wind, it is drawn into glass microfibers with a beating degree of SR°21 at high speed. At the same time, the same molten glass flows into 2 with a temperature of 1005°C and a pore size of 16mm. # The molten glass stream formed by the alloy bushing flows into 2 with a temperature of 985°C, a number of holes of 14500, and a rotation speed of 3400rpm. # The centrifugal disc is pulled into glass microfibers with a beating degree of SR°17 at high speed under the action of the centrifugal force of the high-speed rotating centrifugal disc in the centrifuge and the high-pressure extension wind. At the same...

Abstract

The invention relates to a heat-insulating and sound-insulating glass microfiber wool for low-frequency noise and a preparation method thereof. The heat-insulating and sound-insulating glass microfiber wool for low-frequency noise comprises, in mass percentage, 85-95 wt% of ultra-fine glass fiber wool, The modified single-component water-based resin is 5-12wt%, the coupling agent is 1-3wt% and the water-based color paste is 0.5-1wt%. The superfine glass fiber wool is composed of glass microfibers with three degrees of beating. Mixed solution B formed by uniformly mixing one-component water-based resin and coupling agent, mixed solution A formed by uniformly mixing type A modified single-component water-based resin and water-based color paste, and mixed solution B and mixed solution A were divided into two parts The surface is coated with glass microfibers in one step and formed into glass microfiber wool. The thermal insulation and sound insulation glass microfiber cotton prepared by the invention has good softness, strong hydrophobicity, high mechanical strength and excellent thermal insulation and sound insulation performance against low-frequency noise.

Description

technical field [0001] The invention relates to a heat-insulating and sound-insulating glass microfiber wool for low-frequency noise and a preparation method thereof, belonging to the technical field of glass microfiber composite materials. Background technique [0002] The ultra-fine glass fiber cotton produced by centrifugal blowing method has porous, low bulk density, fluffy and soft, interwoven inner fibers and excellent heat insulation and sound absorption properties, and can be used in construction, home appliances, transportation and other industrial fields. When ultra-fine glass fiber wool is used in the field of sound absorption and heat insulation, the degree of fiber thickness has a very significant effect on its heat insulation and sound insulation performance. Generally, when the fiber diameter is thinner, the more semi-connected pores formed in the ultra-fine glass fiber wool, the lower the thermal conductivity and the higher the sound insulation decibel. The ...
