In-situ polymerization composite surface sizing system and surface sizing craft for needle punching non-woven fabrics

Abstract

The invention discloses an in-situ polymerization composite surface sizing system and a surface sizing craft for needle punching non-woven fabrics, namely a chemical process that organic monomers are polymerized to form high polymer materials and a flame planting composite process that non-woven fabrics are soaked by the organic monomers are combined in the same production line in a situ mode. The surface sizing system comprises a glue producing device, a glue seeping/flame planting sizing device and a drying device. The surface sizing craft achieved through the surface sizing system comprises the steps of (1) adding an emulsifying agent, a buffer agent and some water inside a burdening pot, stirring, evenly mixing the emulsifying agent, the buffer agent and the water, adding butyl mehtacrylate and methyl metacrylate, stirring, adding an initiating agent, stirring for an hour in a temperature range of 60 to 70 DEG C to form prepolymer, adding remaining water, stirring, evenly mixing the remaining water and the prepolymer, obtaining water miscible liquid, cooling the water miscible liquid to room temperature, introducing the water miscible liquid to a mixing pot, adding a polysaccharide compound into the mixing pot, mixing the polysaccharide compound with the water miscible liquid in a continuously stirred mode, forming suspension liquid; (2) treating the needle punching non-woven fabrics in a sizing mode through the glue seeping/flame planting sizing device; and (3) drying the needle punching non-woven fabrics and finalizing the design.

Description

technical field [0001] The invention relates to a gluing system, in particular to a gluing system and a gluing process for in-situ polymerization and compounding of needle-punched nonwoven fabrics. The invention belongs to the field of preparation of fiber composite materials. Background technique [0002] In recent years, the application of fiber composite materials prepared by gluing needle-punched non-woven fabrics in medical and sanitation, air purification, sewage treatment, transportation, footwear and clothing has been expanding; at the same time, the price of oil has continued to rise, resulting in The price of raw materials for non-woven fabrics is constantly rising; moreover, the number of production lines for the preparation of non-woven fabric composite materials is increasing day by day. Therefore, the development of new processes for the preparation of low-cost, high-performance non-woven composite materials has attracted much attention. Since the gluing proc...

Problems solved by technology

[0006] The existing gluing equipment adopts a single sizing method, and the dipping method is costly, and the production of some products cannot be realized by using the spraying method. For example, it is difficult to apply a large amount of glue in an instant or the fine holes of the nozzle will be blocked when the viscosity of the adhesive is too high.
