Problems solved by technology

[0003] But at present, most of the existing warm clothes use electric heating wire and carbon fiber as the heating element. The heating module composed of the traditional metal electric heating wire has a large volume, thick, hard and poor flexibility, which causes inconvenience to the movement and is very difficult to use. It is troublesome, poor comfort, and cannot be folded, so it is inconvenient to store and carry
[0004] However, carbon fiber is used as the heating element, and the carbon fiber thread is directly woven on the canvas; the two ends of the carbon fiber thread are braided with metal wires to make a heating cloth in parallel, and its thickness is still relatively thick, so it can only be used with It can be used together with thicker coats and other clothes, but it cannot be used on thinner thermal underwear and special-shaped products, and it has poor flexibility, causing inconvenience to movements, and it will shrink and expand due to temperature changes after use. And after twisting, the wire weaving will be loosened, resulting in poor contact of carbon fiber wires, flashover and other faults
If carbon fiber is used alone as a heating element instead of heating cloth, because of the high internal resistance of carbon fiber wire, the carbon fiber wire can only be designed in a short length (within 5cm), and its heating area is small. For this reason, multiple carbon fiber wires need to be connected in parallel by riveting to form a surface heating effect. Because there are too many riveting positions, the temperature is uneven (the temperature of the riveting position is high), and after use, it will shrink and expand due to temperature changes. After twisting, the riveting position will be loosened or disconnected, which will easily lead to faults such as poor contact and flashover, which will bring inconvenience to people's lives

Embodiment 1

[0028] Embodiment 1: see figure 1 and figure 2 , a method for manufacturing a flexible mesh heating wire provided by an embodiment of the present invention, which includes the following steps.

[0029] (1) Prepare a flexible sheet carrier 1 .

[0030] (2) Prepare the silver ion paste 2, apply and print the silver ion paste 2 on the surface of the flexible sheet carrier 1 according to the pre-designed heating wire circuit shape trajectory, and leave the flexible sheet carrier 1 uncoated after curing The blank part printed with silver ion paste 2 is cut off, and after the cutting is completed, a silver ion heating circuit 3 consistent with the shape track of the pre-designed heating wire circuit is obtained, and the silver ion heating circuit 3 has two terminals 31, A plurality of curvilinear heating wire loops 32 are integrally connected in parallel between the two terminals 31 .

[0031] Detecting the resistance value of the silver ion heating circuit 3 solidified on the s...

Embodiment 2

[0045] Example 2: see image 3 , a flexible mesh heating wire manufacturing method and its products provided by the embodiment of the present invention are basically the same as in embodiment 1, the difference is that the step (2) is different and the weight percentage of each component of the silver ion paste is different , the specific differences are as follows.

[0046] (2) Prepare the silver ion paste 2, apply and print the silver ion paste 2 on the surface of the flexible sheet carrier 1, and after curing, apply and print the silver ion paste according to the pre-designed heating wire circuit shape track The flexible sheet carrier 1 of the material 2 is cut, and after the cutting is completed, a silver ion heating circuit 3 consistent with the shape track of the pre-designed heating wire circuit is obtained, and the silver ion heating circuit 3 has two terminals 31, A plurality of curvilinear heating wire loops 32 are integrally connected in parallel between the two ter...

Embodiment 3

[0048] Embodiment 3: A kind of flexible mesh heating wire manufacturing method and its products provided by the embodiment of the present invention are basically the same as Embodiment 1, one of the differences is that the weight percentages of the components of the silver ion paste 2 are different , each component and percentage by weight of this silver ion paste 2 are as follows: silver powder 75%, bisphenol A type epoxy resin 5%, acid anhydride curing agent 5%, methyl imidazole 2%, diethylene glycol butyl ether acetic acid 9% ester, 2% reactive diluent, 1.2% tetraethyl titanate, 0.8% polyamide wax.

[0049] The second difference is that, see Figure 4 , The silver ion heating circuit 3 has two terminals 31, and a plurality of linear heating wire circuits 32 are integrally connected in parallel between the two terminals 31.

Abstract

The invention discloses a method for manufacturing flexible mesh heating wires, and further discloses a product manufactured by implementing the method. The product comprises a silver ion heating loop which is provided with two terminals. A plurality of curved or linear heating wire loops are integrally connected between the two terminals in parallel. An insulation film covers one surface of the silver ion heating loop, and a flexible chip carrier covers the other surface of the silver ion heating loop. A gum layer covers the other surface of the flexible chip carrier. The silver ion heating loop is integrally cured and formed, free of contact combinations, good in connection effect, capable of being washed or folded for use, convenient to use, sanitary, flexible, light, long in service life and high in portability and has the deodorization effect, and motion flexibility of people is greatly improved. In addition, low-voltage operation is adopted, working stability is good, safety is high, and the product can be attached to the surface of any special-shaped rigid or soft material for use and can be directly attached to the surface of the human body for use, and is large in application range, good in warm keeping effect, and convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of heat-retaining heating wires, in particular to a method for manufacturing flexible mesh heating wires and products thereof. Background technique [0002] To keep warm outdoors, especially in severe cold areas, mainly rely on cotton trousers, cotton wool trousers, wool trousers, etc. for heating. With the development of science and technology, people have invented warm clothes on the basis of ordinary clothes. [0003] But at present, most of the existing warm clothes use electric heating wire and carbon fiber as the heating element. The heating module composed of the traditional metal electric heating wire has a large volume, thick, hard and poor flexibility, which causes inconvenience to the movement and is very difficult to use. It is troublesome, poor in comfort, and cannot be folded, making it inconvenient to store and carry. [0004] However, carbon fiber is used as the heating element, and the carb...
