[0001] The utility model relates to the technical field of foam cotton application, in particular to a high-performance foam cotton. Background Art

[0002] Foam is a plastic material with independent bubble structure, which is widely used in various heat preservation, sound insulation and shockproof occasions. Foam usually refers to plastic products with many small pores or cells inside. These bubbles can be closed or open, giving foam unique physical properties, such as light weight, good elasticity and excellent heat and sound insulation performance.

[0003] The existing foam cotton is only a simple single-layer setting, and its own performance is relatively simple, so that during use, its single characteristic makes the overall toughness and strength relatively low. It will tear during long-term use, which can easily cause damage to it, reducing the service life of the foam cotton. Therefore, the utility model proposes a high-performance foam cotton. Utility Model Content

The first foam cotton layer enables the foam cotton to maintain a certain hardness and elasticity as a whole.

[0008] The utility model is further configured as follows: the first foam cotton layer and the second foam cotton layer are arranged as one body through relative extrusion molding by the glass fiber layer.

[0009] Through the above technical solution, the glass fiber layer can be completely sunken into the first foam cotton layer and the second foam cotton layer, thereby preventing cracking and warping at the relative connection points during use, and improving the strength of the foam cotton during use.

[0010] The utility model is further configured as follows: the glass fiber layer includes a plurality of first transverse fiber strips, a plurality of second transverse fiber strips, a plurality of first longitudinal fiber strips and a plurality of second longitudinal fiber strips, and the plurality of first transverse fiber strips and the second transverse fiber strips are arranged to be cross-entangled with the plurality of first longitudinal fiber strips and the plurality of second longitudinal fiber strips.

[0011] Through the above technical solution, the cross-entangled transverse fiber strips and longitudinal fiber strips can be used to improve the strength and toughness of the entire glass fiber layer, thereby improving the strength and toughness of the entire foam and increasing its life during use.

[0012] The utility model is further configured as follows: a plurality of the first transverse fiber strips and the second transverse fiber strips are arranged to be alternately and equidistantly distributed in the transverse direction.

[0013] Through the above technical solution, when a plurality of first transverse fiber strips and second transverse fiber strips are wound and connected, the equidistant arrangement can improve the connection firmness between the longitudinal fiber strips.

[0014] The utility model is further configured as follows: a plurality of the first longitudinal fiber strips and the second longitudinal fiber strips are arranged to be alternately and equidistantly distributed in the longitudinal direction.

[0017] Through the above technical scheme, when multiple first transverse fiber strips, multiple second transverse fiber strips, multiple first longitudinal fiber strips and multiple second longitudinal fiber strips are intertwined, they can be tightly connected and fixed using the wave shape, thereby making the glass fiber layer more firm and stable.

[0018] The beneficial effects of the utility model are as follows:

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0028] like Figure 1-Figure 5As shown, a high-performance foam cotton comprises a foam cotton body 1. The foam cotton body 1 is arranged in three layers. The top layer of the foam cotton body 1 is arranged as a first foam cotton layer 2, and the bottom layer of the foam cotton body 1 is arranged as a second foam cotton layer 3. The thickness of the second foam cotton layer 3 is twice that of the first foam cotton layer 2, so that the second foam cotton layer 3 can provide better support during use of the foam cotton, increase the overall compressive strength, and better absorb and disperse the impact force, improve the impact resistance of the material, and play a good heat insulation role, helping the material to remain stable in a high temperature environment. The first foam cotton layer 2 enables the foam cotton to maintain a certain hardness and elasticity as a whole. The first foam cotton layer 2 and the second foam cotton layer 3 are arranged as a whole by relative extrusion molding through the glass fiber layer 4, so that the glass fiber layer 4 can be completely immersed in the first foam cotton layer 2 and the second foam cotton layer 3, thereby preventing cracking and warping at the relative connection during use, and improving the strength of the foam cotton during use.

[0029] like Figure 4 and Figure 5 As shown, the first foam cotton layer 2 and the second foam cotton layer 3 are fixedly connected to the opposite surfaces thereof with a glass fiber layer 4, and the glass fiber layer 4 includes a plurality of first transverse fiber strips 41, a plurality of second transverse fiber strips 42, a plurality of first longitudinal fiber strips 43 and a plurality of second longitudinal fiber strips 44. The plurality of first transverse fiber strips 41 and the second transverse fiber strips 42 are arranged alternately and equidistantly in the transverse direction, so that when the plurality of first transverse fiber strips 41 and the second transverse fiber strips 42 are wound and connected, the equidistant arrangement can improve the connection firmness between the longitudinal fiber strips, and the plurality of first longitudinal fiber strips 43 and the second longitudinal fiber strips 44 are arranged alternately and equidistantly in the longitudinal direction, so that when the plurality of first longitudinal fiber strips 43 and the second longitudinal fiber strips 44 are wound and connected, the equidistant arrangement can improve the connection firmness between the transverse fiber strips, and the plurality of first transverse fiber strips 41 and the second transverse fiber strips 42 are arranged alternately and equidistantly in the longitudinal direction. The fiber strips 42 are arranged to be cross-entangled with the multiple first longitudinal fiber strips 43 and the multiple second longitudinal fiber strips 44. The cross-entangled transverse fiber strips and longitudinal fiber strips can improve the strength and toughness of the entire glass fiber layer 4, thereby improving the strength and toughness of the entire foam and improving its life during use. The multiple first transverse fiber strips 41, the multiple second transverse fiber strips 42, the multiple first longitudinal fiber strips 43 and the multiple second longitudinal fiber strips 44 are all arranged in a wavy shape, and when they are arranged in a winding manner, the protrusions and depressions are arranged alternately, so that when the multiple first transverse fiber strips 41, the multiple second transverse fiber strips 42, the multiple first longitudinal fiber strips 43 and the multiple second longitudinal fiber strips 44 are intertwined with each other, they can be tightly connected and fixed using the wavy shape, thereby making the glass fiber layer 4 more firm and stable.

[0030] When the utility model is in use, a glass fiber layer 4 is squeezed and arranged between the first foam cotton layer 2 and the second foam cotton layer 3, so that the high strength and high toughness of the glass fiber can be utilized, so that the toughness and strength of the entire foam cotton can be improved during use, and tearing damage during installation and use can be avoided. The first foam cotton layer 2 and the second foam cotton layer 3 are set to different thicknesses, so that the second foam cotton layer 3 can provide better supporting force during use of the foam cotton, increase the overall compressive strength, and at the same time better absorb and disperse impact force, improve the impact resistance of the material, and can play a good heat insulation role, helping the material to remain stable in a high temperature environment. The first foam cotton layer 2 enables the foam cotton to maintain a certain hardness and elasticity as a whole, thereby improving the performance and service life of the foam cotton.
