Embodiment 1

[0041] Electrostatic flocking high-elastic sound-absorbing flame-retardant melt-blown nonwoven fabric, including upper base fabric 1, lower base fabric 2, sound-absorbing particles 3, 3', upper adhesive film 4, lower adhesive film 4', fluff 5 And flame retardant powder 6, 6'. The upper base fabric 1 and the lower base fabric 2 are non-woven fabrics prepared by the melt-blown method. The sound-absorbing particles 3, 3' and flame-retardant powders 6, 6' are uniformly mixed, and the melt is extruded from the spinneret hole and subjected to high-speed hot air flow. When the superfine fibers are stretched to reach the condensed net curtain, the mixture of sound-absorbing particles 3, 3' and flame-retardant powder 6, 6' is blown and attached to the superfine fibers by hot air blowing, and the sound-absorbing particles 3 The superfine fiber with flame-retardant powder 6 relies on self-thermal bonding to make the upper base fabric 1, and the ultra-fine fiber with sound-absorbing parti...

Abstract

The invention relates to a preparation method of an electrostatic flocking type high-elastic sound-absorption inflaming-retarding melt-blown nonwoven fabric, belonging to the field of the textile technology. Superfine fibers in a high-elastic sound-absorption material, prepared by a melt-blown method, are thermally-bonded to form a base cloth, sound-absorption granules and inflaming-retarding powder are bonded on the superfine fibers, and the opposite surfaces of the upper-layer base cloth and the lower-layer base cloth are respectively coated with an upper-layer adhesive film and a lower-layer adhesive film, fuzz is vertically and fixedly bonded between the upper-layer base cloth and the lower-layer base cloth by the upper-layer adhesive film and the lower-layer adhesive film. The preparation method comprises the following steps: (1) preparing mixture; (2) performing blowing-in of the mixture; (3) coating adhesive; (4) performing electrostatic flocking; (5) baking and drying; (6) absorbing fuzz; (7) compositing the base cloths; (8) baking and drying; and (9) winding. The electrostatic flocking type high-elastic sound-absorption inflaming-retarding melt-blown nonwoven fabric has the characteristics of large specific surface area, small pore diameter, high porosity and good elasticity, can be used for improving the sound-absorption effect and has an inflaming-retarding function.

Description

technical field [0001] The invention relates to an electrostatic flocking type high-elastic sound-absorbing flame-retardant melt-blown nonwoven fabric and a manufacturing method thereof, belonging to the field of textiles. Background technique [0002] Noise pollution has become a problem in the contemporary world. In the increasingly rapid urbanization process, industry and transportation are developing rapidly, and people are affected by noise to varying degrees. After the human body is exposed to a strong noise environment for a certain period of time, there will be hearing loss and other phenomena. Studies have shown that long-term exposure to noise above 80dB may damage hearing. After 20 years of working in an environment above 85dB, 10% of people will be deaf, and if it is above 90dB, the proportion of deafness will be greater than 20%. To control noise, we mainly start from three aspects: 1. To suppress the generation of noise, that is, to control it from the source;...
