Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
The present invention will be described in detail with reference to fig. 1 and 2. The utility model relates to a special packaging material for container desiccant, which comprises a water repellent non-woven fabric layer 1, a breathable film 2 and an ES non-woven fabric layer 3; the water-repellent non-woven fabric layer 1 and the breathable film 2 are compounded through a first adhesive layer 4; the breathable film 2 and the ES non-woven fabric layer 3 are compounded through a second adhesive layer 5; the ES non-woven fabric layer 3 is a non-woven fabric made of ES short fibers through mechanical reinforcement.
Further, the utility model discloses in, refuse water non-woven fabrics layer 1 including the first spunbond layer 11, first meltblown layer 12, second meltblown layer 13, third meltblown layer 14 and the second spunbond layer 15 that set gradually. Namely SMMMS non-woven fabric, the SMMMS non-woven fabric has light weight, softness, high strength and puncture resistance. The anti-sticking is combined with the melt-blowing process, so that the strength of the material is increased. The polypropylene resin is used as a main production raw material, the specific gravity is only 0.9, the specific gravity is only three fifths of that of cotton, and the polypropylene resin has fluffiness and good hand feeling. Is formed by light-point hot melting and bonding of (2-3d) fine fibers. The finished product has moderate softness and comfortable sensation. The product is formed by directly laying polypropylene spinning into a net and thermally bonding, has better strength than common short fiber products, and has non-directional strength and similar longitudinal and transverse strength. The polypropylene slice has no water absorption, zero water content, good water repellency of finished products, porosity formed by 100 percent of fibers, good air permeability, easy maintenance of dry and comfortable cloth surface and easy washing.
Furthermore, the ES fiber used in the ES non-woven fabric layer used in the utility model is the fiber with PP/PE sheath-core structure, and the outer layer is the low melting point fiber. The packaging material with the ES non-woven fabric layer has heat sealability. The ES non-woven fabric layer is formed by fusing, extruding, stretching into filaments, cutting and carding PE + PP mixed master batches to form a fiber web, and then mechanically reinforcing the fiber web to form the non-woven fabric. The ES fiber non-woven fabric is soft and comfortable, has good air permeability, no stimulation, strong mechanical property and tearing resistance. The modified material has high sealing strength (no leakage of materials and powder), high drop strength and extrusion resistance. Therefore, the packaging material compositely manufactured by the method has wide application range and strong environmental adaptability. In addition, the short fiber non-woven fabric has high density, compact structure and high strength. The prepared ES non-woven fabric layer 3 has a smooth surface and a rough surface.
Further, the breathable film 2 used was a single-sided corona PE breathable film. The PE breathable film has an average pore size of 35-55 microns, so that the packaging material has certain hydrostatic pressure resistance, and the bag breaking phenomenon of absorbed water in the movement process can be avoided in the action process of the packaging material. And both sides of the PE breathable film were corona treated.
Furthermore, the corona surface of the breathable film 2 is compounded with the rough surface of the ES non-woven fabric 3. Can ensure that the fabric still has good air permeability and compounding fastness after the meeting.
When the water-repellent non-woven fabric layer 1, the breathable film 2 and the ES non-woven fabric layer 3 are compounded, a dry compounding process is mainly adopted. The method comprises the following specific steps:
firstly, compounding a breathable film 2 and an ES non-woven fabric layer 3 into a semi-finished product. In the compounding process, the corona surface of the breathable film 2 is compounded with the rough surface of the ES non-woven fabric 3, and the glue coating amount of the second adhesive layer 5 is 6-7g/m2. The temperature of the drying tunnel 4 area of the compound equipment is respectively 45 degrees, 50 degrees, 55 degrees and 60 degrees. After compounding, the semi-finished product enters a drying room for curing and curing treatment for about 24-48 h.
And secondly, compounding the semi-finished product with SMMMS non-woven fabric. The SMMMS non-woven fabric has rolling points, so that one side of the SMMMS non-woven fabric has obvious rolling points, and the other side of the SMMMS non-woven fabric has shallow rolling points. In the step, the surface with shallow spots and lines of the SMMMS non-woven fabric is compounded with the air-permeable film surface of the semi-finished productAnd (6) mixing. The glue amount is controlled to be 5-6g/m2The temperature of the drying tunnel 4 area of the compound equipment is respectively 40 degrees, 50 degrees, 55 degrees and 60 degrees. And (4) putting the compounded finished product into a drying room for curing and preserving for about 36-48 h.
In the two compounding processes, consistent gluing wire rollers are adopted to control the overall gluing amount and gluing state of the finished product. Too little gluing amount easily causes the layering of packing material products, and too much gluing amount easily causes the influence on the air permeability of the products after curing.
The use of the water-repellent non-woven fabric SMMMS ensures that the packing material product has certain water locking performance. The use of the breathable film with the average pore diameter of 35-55 microns ensures that the packing material has certain hydrostatic pressure resistance, namely, the packing material can not be broken by absorbed water in the movement process in the function process, so that the packing material is more suitable for being used as a container desiccant packaging material.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
