Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the multi-layer composite disposable drape comprises:

the base paper 1 is a commercially available product, and white and yellow base paper can be selected.

A plurality of base papers 1 are sequentially stacked and fixed together from top to bottom, and a first glue layer is coated between every two adjacent base papers 1.

The first glue layer is coated in scattered points, the scattered points are coated to form a plurality of glue points in an array, the glue points are designed in quantity as long as the adhesive strength can be met, and meanwhile, the liquid absorption requirement can also be met.

The base paper 1 has 2-6 sheets.

The peripheries of the base papers 1 are flushed, and waste materials caused by trimming can be prevented from being generated after the flushing, so that the manufacturing cost can be further reduced, and meanwhile, the paper is more energy-saving and environment-friendly.

As shown in figures 1 and 2 of the drawings,

the EVA film 2 and the EVA film 2 belong to commercial products, and are positioned below the base paper 1 at the lowest part, the periphery of the EVA film 2 is flush with the periphery of the base paper 1, and the EVA film 2 and the base paper 1 at the lowest part are fixed together to form a sheet laying body 10;

the base paper 1 and the EVA film 2 are connected and fixed together through hot pressing or cold pressing, and of course, a plurality of base papers can be pressed together in advance or can be pressed together with the EVA film 2.

The same, flush periphery, it can stop the waste material that the side cut led to and produce, also can further reduce manufacturing cost, simultaneously, energy-concerving and environment-protective more.

And secondly, the EVA film 2 is connected with the base paper 1 at the lowest part through a second adhesive layer. The second adhesive layer is in scattered point coating, the scattered point coating is a plurality of adhesive points in an array, and the adhesive point quantity design is only required to meet the adhesive strength.

The glue adopted by the first glue layer and the second glue layer is common glue

As shown in figures 2 and 3 and 4,

the upper surface of the sheet paving body 10 is provided with a plurality of forming depressions 10a which are distributed in an array manner, the forming depressions can enlarge the capacity, and the inner walls of the forming depressions 10a are distributed in an inclined manner downwards and inwards. The inclined inner wall can facilitate the inflow of liquid, the guiding effect is achieved, meanwhile, the inclined inner wall is convenient to form, press and process, and break away after pressing, the production efficiency can be improved, and the use performance of products can be improved.

The molding recess 10a is any one of a rectangular recess, a circular recess, and a triangular recess. Of course, other shapes are possible as long as the requirement for capacity enlargement can be satisfied, and the molding process is also simple and convenient.

The total thickness of a plurality of pieces of base paper 1 is larger than that of the EVA film 2. This structural design makes it possible to increase the liquid absorption properties, since the base paper has very good liquid absorption capacity and, at the same time, provides a high level of comfort.
