Embodiment 1

[0032] Polyester fibers, polypropylene fibers, anion fibers and antistatic fibers with diameters of 37 μm, 18 μm, 15 μm and 15 μm were selected, and the four kinds of fibers were mixed in a ratio of 50:40:5:5 (mass percentage). After loosening, fine opening, air-flow feeding and carding into a web, pre-needling and main needling reinforcement, then molding and shaping, and then winding to an area density of 500g / m 2 primary products. Configure pressure-sensitive adhesive liquid, which is composed of anionic phosphorus-based flame retardant and acrylate emulsion-type pressure-sensitive adhesive, and the monomer composition of pressure-sensitive adhesive is acrylic acid, diaminoethyl methacrylate and methyl methacrylate The ratio of copolymer emulsion, flame retardant and pressure-sensitive adhesive is 10:90 (mass percentage), and after the rolled primary product is coated with the pressure-sensitive adhesive of the above composition, it is compounded with release paper coated w...

Embodiment 2

[0034] Polyester fibers, polypropylene fibers, anion fibers and antistatic fibers with diameters of 42 μm, 25 μm, 18 μm and 18 μm were selected, and the four kinds of fibers were mixed in a ratio of 55:35:5:5 (mass percentage). After loosening, fine opening, air-flow feeding and carding, after pre-needling and main needling reinforcement, it is molded and shaped, and then wound to an area density of 700g / m 2primary products. Firstly, the rolled primary product is coated with anionic phosphorus-based flame retardant, and then coated with a hot-melt adhesive based on styrene-butadiene-styrene copolymer, the mass percentage of glue and flame retardant It is 80:20, and then compounded with silicone-coated release paper, dried by hot pressing, and then trimmed, then wound to form a self-adhesive non-woven material.

Embodiment 3

[0036] Polyester fibers, polypropylene fibers, negative ion fibers and antistatic fibers with diameters of 42 μm, 25 μm, 18 μm and 18 μm were selected, and the four kinds of fibers were mixed in a ratio of 40:45:7:8 (mass percentage). After loosening, fine opening, air-flow feeding and carding, after pre-needling and main needling reinforcement, it is molded and shaped, and then wound to an area density of 700g / m 2 primary products. The rolled primary product is first coated with an anionic phosphorus-based flame retardant, and then coated with a hot-melt adhesive based on a styrene-isoprene-styrene copolymer base polymer. The mass percentage of glue and flame retardant It is 75:25, and then compounded with silicone-coated release paper, dried by hot pressing, and then trimmed, then wound to form a self-adhesive non-woven material.

Abstract

The invention relates to a building multifunctional nonwoven material, which comprises a substrate and a bottom modified layer, wherein, the compositions by mass percentage of the materials of the substrate are: 30 to 70 percent of polyester fibers, 30 to 50 percent of polypropylene fibers, more than 0 percent and less than or equal to 10 percent of negative ion fibers and more than 0 and less than or equal to 10 percent of static fibers; and the bottom modified layer comprises fire retardant. The building multifunctional nonwoven material has the properties of fire resistance, static resistance, heat insulation, sound absorption and friendly environment, and simultaneously is simple and convenient to use, can be cut randomly and can be firmly glued on a metope at any position without the necessity of a constructor. Moreover, the material has beautiful appearance and varied flower patterns and colors and can be used as a novel building decorative material.

Description

technical field [0001] The invention relates to a non-woven material for construction, in particular to a multifunctional non-woven material for construction with the functions of heat insulation, flame retardancy, antistatic and negative ions. Background technique [0002] Existing thermal insulation, thermal insulation and sound-absorbing materials for buildings mainly use materials such as glass fiber, rock wool and sponge sound-absorbing cotton. Long-term construction is harmful to people, and has disadvantages such as strong water absorption and poor drainage. [0003] As the world's energy continues to be tense and environmental pollution intensifies, the demand for energy-saving, environmentally friendly and multi-functional building materials is getting higher and higher, because it is a high-quality residential building with high efficiency, low consumption, environmental protection and energy saving, health and comfort, and ecological balance. The necessity of con...
