Description
Technical Field
The invention relates to the technical field of production equipment of flame-retardant acoustic boards, in particular to a full-automatic one-step forming production line of a polyester fiber flame-retardant acoustic board.
Background
Fire is the most common disaster which seriously harms people's lives and properties, directly affects economic development and social stability. In recent years, with the wide utilization of new energy, new materials and new equipment, the continuous expansion of urban construction scale and the improvement of the living standard of people's material and culture, the personal casualties and property losses caused by fire disasters are increasing. Therefore, the fire-proof performance of the sound-absorbing material is of great importance, and the concept of fire-proof has been the most important safety requirement in various fields. The flame-retardant fiberboard is made, the problem that the traditional interior decoration material is flammable is solved, the flame-retardant fiberboard produced by taking wood as a main raw material can substantially overcome the defects of wood, the physical and mechanical properties of the wood can be greatly improved, and meanwhile, the flame-retardant plywood also overcomes the defect that the common plywood is easy to burn, and the flame-retardant property of the plywood is effectively improved. A composite flame retardant and a method for preparing a flame retardant fiberboard thereof such as disclosed in CN 105131627 a, a flame retardant disclosed in CN 101892057 a, a flame retardant fiberboard and a manufacturing method thereof. The flame-retardant fiberboard takes the wood as the raw material, so that a large amount of wood raw materials are needed, the cost is high, the price is high, the production process route is complex, the density is high, the weight is heavy, the strength of workers in the installation and construction process is high, the requirement of installation and fixation on the wall surface is high, and the sound absorption and flame retardance of the flame-retardant fiberboard can meet the requirement, but still have the defects.
Therefore, the polyester fiber sound-absorbing board with more excellent performance is provided, is totally called as a polyester fiber decorative sound-absorbing board and is a decorative material which is prepared by taking polyester fiber as a raw material through hot press molding and has the sound-absorbing function. The polyester fiber acoustic board has the characteristics of sound absorption, heat insulation and heat preservation, and the board is uniform and firm in material, rich in elasticity, toughness, wear resistance, impact resistance, tearing resistance, difficult to scratch and large in board width. The sound-absorbing material has the characteristics of decoration, heat preservation, flame retardance, environmental protection, light weight, easiness in processing, stability, impact resistance, simplicity and convenience in maintenance and the like, is a preferred decoration sound-absorbing material for indoor decoration, and is widely applied to activity places gathered by the public, such as families, markets, hotels, KTVs, movie theaters, dance halls, auditoriums, multifunctional halls, gymnasiums and the like. The production process of the polyester fiber sound-absorbing board generally comprises the following steps: opening, cotton mixing, carding, lapping, needling, oven hot press molding, air cooling treatment, edge cutting and the like. To impart flame retardant properties to polyester fiber sound-absorbing panels, flame retardants are added. The addition method mainly comprises a plate surface coating method and an addition method. The additive method, i.e. the flame retardant treatment before board formation, is to physically blend the flame retardant with the fibers by simple mechanical stirring or to spray the flame retardant on the fibers and then press the fibers into boards. Although the whole board has the flame retardant effect, the method has large consumption of the flame retardant, and the internal bonding strength of the board is reduced along with the addition of the flame retardant, so that the mechanical property of the board is influenced, and the use of the board is limited; because the prior polyester fiber flame-retardant acoustic board is prepared by mixing, carding and lapping polyester fibers, low-melting-point sheath-core fibers and three-dimensional hollow fibers, the addition method is not suitable for the production of the polyester fiber flame-retardant acoustic board. The coating method is that after the fiber is formed into a board, the surface of the fiber board is uniformly coated with a flame retardant or a flame retardant coating to prepare the flame retardant fiber board. Although the method has the advantages of external layer protection, direct flame retardant effect and small using amount, the method also has the problems of poor durability, nonuniform spraying, the relation between the adhesive property of the adhesive and the addition amount of the flame retardant and the like, and once the flame retardant surface layer is damaged, the whole plate has no flame retardant effect any more.
CN1335218A discloses a non-woven fiber board and a manufacturing method thereof, the board is a board formed by mixing a plurality of different short fibers together, and performing needle punching forming and heating setting, and is characterized in that the mixed short fibers are formed by mixing 50-60% of polyester fibers, 20-30% of polyacrylonitrile fibers and 15-25% of polypropylene fibers in percentage by weight. The manufacturing method is characterized in that mixed short fibers are loosened, carded and made into a fiber web, the fiber web is densely needled on a needling machine to be made into a base fabric at one time, the base fabric is heated until polypropylene fibers are melted, the surface of the base fabric is flat and the thickness of the base fabric is corrected to the thickness of a product by pressing, and the finished product is obtained after shaping. CN 102896684A discloses a preparation system of a polyester fiber heat-preservation acoustic board, wherein during production, raw materials enter the preparation system from a raw material feeding device and then enter a coarse opener for mixing and realizing coarse opening; then, finely opening the raw materials by using a fine opener, and outputting the raw materials to an oven; the raw materials are heated by the oven, so that the skins of the low-melting-point skin-core fibers in the raw materials are melted and then mixed and bonded with other raw materials to form a three-dimensional net structure; the cold water roller cools and rolls the raw material flowing out of the discharge hole of the oven to shape the raw material; and the splitting machine shears and trims the cooled and rolled raw materials, and then outputs a final product.
Although the above two patent solutions disclose the production of fiber board by non-woven method and the process of preparing non-woven fabric by using chemical fiber, the fiber board produced by the two methods has no flame retardancy.
CN1635211A discloses a flame-retardant coating process for heavy fabrics, which achieves the purpose of thickening by mechanically foaming low-viscosity flame-retardant glue, so that the flame-retardant glue has coating processability, foams are crushed in the blade coating and extrusion process after being coated by a scraper, the foams are changed into low-viscosity flame-retardant glue again, the low-viscosity flame-retardant glue permeates into a coated substrate, and then the low-viscosity flame-retardant glue is dried, so that the overall flame-retardant performance of the fabrics meets the requirement.
