Embodiment 1

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

[0036]

[0037] preparation:

[0038] The above-mentioned components are added one by one according to conventional steps using foaming equipment to obtain the cross-linked polyethylene composition 1.

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

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

[0041] Quilt the above warming pad; quilting into parallel rosettes.

[0042] Cutting: Cut into pieces according to the size of the product, which can be cut with manual scissors, or can be punched with a punch using a mold;

Embodiment 2

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

[0045]

[0046]

[0047] The preparation is the same as in Example 1, except that attention should be paid to the uniformity of dispersion when polyurethane is added.

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

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

[0050] Quilt the above warmer; quilting into a square shape.

[0051] Cutting: Cut into pieces according to the size of the product, which can be cut with manual scissors, or can be punched with a punch using a mold;

Embodiment 3

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

[0054]

[0055] Prepare with embodiment 2.

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

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

[0058] Quilt the above insulation pad; can be quilted into waves.

[0059] Cutting: Cut into pieces according to the size of the product, which can be cut with manual scissors, or can be punched with a punch using a mold;

[0060] The cross-linked polyethylene composition prepared above has a fine independent cell structure, which can effectively reduce the energy exchange caused by air convection, and is non-toxic, odorless, easy to process, can be cut arbitrarily, and is bonded with various materials. A high-efficiency, energy-saving, and environmentally-...

Abstract

The invention provides a cross-linked polyethylene composition and a use thereof. 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. It can further comprise a nanometer infrared reflecting substance, polyester, polyamide, polypropylene, acrylic acid, aromatic polyamide, polybenzimidazole, silicone, and the like. The cross-linked polyethylene composition according to 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 directions of the cross-linked polyethylene composition are almost consistent, the interior of a foamed substance is 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 with the cross-linked polyethylene composition, the heat of the human body is rebounded by the infrared reflecting substance in the cross-linked 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 crosslinked polyethylene composition and its application. Background technique [0002] At present, in the cold winter, sleep mainly depends on air conditioners and electric blankets; air conditioners consume a lot of electric energy, generate noise, and use Freon, which has a great destructive effect on the ozone in the atmosphere and makes ultraviolet radiation more and more serious; another On the one hand, electric blankets not only consume energy, but also have great potential safety hazards. If you don’t use these products, it will be very cold in winter and it will be difficult to fall asleep, especially when 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. Th...
