Embodiment 1

[0035] Cross-linked polyethylene composition 1, the composition formula includes:

[0036]

[0037] preparation:

[0038] Using foaming equipment, add the above-mentioned components one by one according to the conventional steps to obtain cross-linked polyethylene composition 1.

[0039] The cross-linked polyethylene composition 1 prepared above is used to prepare an insulation pad, and the specific structure is as follows:

[0040] From top to bottom, there are sandwich mesh cloth layer, spray cotton layer, cross-linked polyethylene composition layer and T / C cloth layer.

[0041] Quilt the above-mentioned insulation pad; quilt into parallel rosettes.

[0042] Cutting: Cut into pieces according to the size of the product, which can be cut with manual scissors, or use a mold to punch the pieces with a punch; the edge is ready.

Embodiment 2

[0044] Cross-linked polyethylene composition 2, the composition formula includes:

[0045]

[0046]

[0047] The preparation is the same as in Example 1, except that when adding polyurethane, pay attention to the uniformity of dispersion.

[0048] The cross-linked polyethylene composition 2 prepared above is used to prepare an insulation pad, and the specific structure is as follows:

[0049] From top to bottom, there are the polar fleece layer, spray cotton layer, cross-linked polyethylene composition layer and chemical fiber cloth layer.

[0050] Quilt the above-mentioned insulation pad; quilt into a square shape.

[0051] Cutting: Cut into pieces according to the size of the product, which can be cut with manual scissors, or use a mold to punch the pieces with a punch; the edge is ready.

Embodiment 3

[0053] The formulas of cross-linked polyethylene compositions 3 and 4 are as follows:

[0054]

[0055] The preparation is the same as in Example 2.

[0056] The above-prepared cross-linked polyethylene composition 3 or 4 is used to prepare an insulation pad, and the specific structure is as follows:

[0057] From top to bottom, they are towel cloth, cross-linked polyethylene composition layer and pure cotton cloth.

[0058] Quilt the above insulation pad; it can be quilted into a wave shape.

[0059] Cutting: Cut into pieces according to the size of the product, which can be cut with manual scissors, or use a mold to punch the pieces with a punch; the edge is ready.

[0060] The cross-linked polyethylene composition prepared above has a fine independent bubble structure, which can effectively reduce the energy exchange caused by air convection, is non-toxic, tasteless, easy to process, can be cut at will, and fits a variety of materials. This is a highly efficient, energy-saving and en...

Abstract

The invention brings forward a crosslinked polyethylene composition and application thereof. A formula for the composition comprises the following components expressed in weight parts: 40 to 50 of polyethylene PE, 0.1 to 2 of an anti-oxidant, 1.5 to 3 of a cross-linking agent, 25 to 40 of a foaming agent and 5 to 15 of a fire retardant. The formula may further comprise a nanometer infrared reflecting substance, polyester, polyamide, polypropylene, acrylic acid, aromatic polyamide, polybenzimidazole, silicone, etc. The crosslinked polyethylene composition provided by the invention is nontoxic and odorless, is easy to process, can be cut at will, bonds with a plurality of materials and is a high efficiency, energy saving and environment friendly material; since foaming direction of the crosslinked polyethylene composition is almost consistent, the interior of a foamed substance regularly arrayed, so slits become narrower, and heat hardly loses; since the nanometer infrared reflecting substance is added, when heat of a human body diffuses outwardly in the form of infrared rays and contacts the crosslinked polyethylene composition, the heat of the human body is rebounded by the infrared reflecting substance in the crosslinked polyethylene composition and acts on the human body again, which enables people to substantially feel warm.

Description

Technical field [0001] The invention relates to the technical field of polyethylene foaming, in particular to a cross-linked polyethylene composition and its application. Background technique [0002] At present, in the cold winter, sleep mainly relies on air conditioners and electric blankets; air conditioners consume a lot of electricity, generate noise, and use Freon, which has a major destructive effect on atmospheric ozone, making ultraviolet radiation increasingly serious; another On the one hand, electric blankets not only consume energy, but also pose great safety risks. If you don't use these products, the winter will be extremely cold and difficult to sleep, especially the moment you enter the bed, it is very unbearable. [0003] Chinese patent 200820121657.3 provides a new thermal insulation pad technology, which provides a gel pad, 70% of which is water with high heat capacity, and its overall existence is in a gel state. The use of the gel pad to make a mattress can ...
