Embodiment Construction

[0033] The technical characteristics of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] In the embodiment of the present invention, polyurethane materials A and B are produced by Shenzhen Youneng Rubber and Plastic Products Co., Ltd., and the product number is 3909500000; among them, 8301A: colorless transparent liquid, 500 ± 100 cps; 8301b: colorless transparent liquid, 800 ± 200cps.

[0035] The preparation method of the embodiment of the present invention is as follows:

[0036] 1) Put the HC-8301A / B raw materials into the A / B tank of the pouring machine respectively, and control the temperature at 20-50°C.

[0037] 2) If necessary, vacuum degas the raw materials of tank A / B first, and then adjust the proportion of tank A and B within the required range.

[0038] 3) Fine-tune the sample sheet, adjust the ratio and curing speed, etc.

[0039] The addition ratio of the polyurethane A mat...

Abstract

The invention discloses a gel heating pad and a method for manufacturing the same. The gel heating pad comprises a fabric layer and at least two heating layers including a first heating layer and a second heating layer; a heat storage layer of phase change materials is arranged between the first heating layer and the second heating layer; an elastic non-glue cotton layer covers the outer side of the first heating layer, and the fabric layer covers the outside of the elastic non-glue cotton layer; a heat-insulation felt is arranged on the outer side of the second heating layer, and an antislip layer is arranged on the outer side of the heat-insulation felt. According to the technical scheme, the gel heating pad and the method have the advantages that the gel heating pad is provided with two layers of carbon fiber heating cloth, accordingly, double-temperature double-control effects can be realized, and the gel heating pad can be utilized after being plugged; a pressure heat conduction effect and a non-pressure heat-insulation effect can be realized by the non-glue cotton layer; heat can be stored for 15-20 minutes under the integral arrangement condition, and the gel heating pad can keep warm for 5-8 hours.

Description

technical field [0001] The invention relates to a gel heat pad and a method for making the gel heat pad. Background technique [0002] It is cold in winter, field work or self-driving travel, etc., often turn on the air conditioner or seat heating when parking, and the engine needs to idle for this purpose. Engine idling for 1 hour can burn about 1-5 liters of dye, and about 500-1000 grams of carbon dioxide will be discharged into the air (according to the information provided by the Japanese Environmental Agency). [0003] In the charging and discharging process of the battery of the car, when the voltage of the battery is lower than the rated voltage, the charging starts; when the voltage of the battery is greater than or equal to the rated voltage, the relay is disconnected and the charging is stopped. When discharging, the rated power is discharged. We can harness this energy. [0004] At present, some cars are equipped with seat heating, and you can also buy heated s...
