Problems solved by technology

[0003] When the thermal fuse is stored, it is often coated with wax on the surface of the fuse to prevent sticking, but the wax coating will affect the normal use of the thermal fuse. When the thermal fuse is used, the wax itself does not flow. If it does not decompose, it will affect the bonding strength of the thermal fuse, especially the polyamide material is easy to absorb water and get wet, so it is not easy to store

Embodiment 1

[0033] Preparation of moisture-proof gel wax:

[0034] Comprising the following parts by weight:

[0035] Calcium acrylate: 20 parts

[0036] Acrylamide: 85 parts

[0037] Ammonium persulfate: 2 parts

[0038] Polyvinyl alcohol: 2 parts

[0039] Sodium chloride: 5 parts

[0040] Water: 100 parts

[0041] Its preparation method is:

[0042] Step a: adding sodium hydroxide to polyvinyl alcohol for saponification to obtain saponified polyvinyl alcohol;

[0043] Step b: adding saponified polyvinyl alcohol, calcium acrylate, acrylic acid amide, and sodium chloride into the solvent, stirring and fully mixing to form a suspension;

[0044] Step c: add ammonium persulfate to the suspension and keep stirring under the protection of nitrogen, raise the temperature to 170°C for 2 hours to obtain a moisture-proof gel, then dry it at 60°C and cool to waxy.

[0045] The stirring rate in the step c is 25r / min.

Embodiment 2

[0047] Commercially available nylon thermal fuses from Hyosung Corporation in South Korea, 70D / 10F, thermal fuses with a melting point of 85°C, after the thermal fuses are passed through the moisture-proof gel wax prepared in Example 1, they are woven into thermal melt fabrics, The specification of the hot-melt cloth is 1mm in hole diameter, take a hot-melt cloth of 10cm*10cm, first heat the hot-melt cloth to 60°C, keep it warm for 1~2min, and then place it on two floors, purchased from Suzhou Haibin Textile Co., Ltd. 70D210T3 grid nylon cloth, heat up to 80°C, and press.

Abstract

The invention discloses an anti-moisture fuse, which comprises a thermal fuse body, and moisture-proof gel wax is attached to the outside of the thermal fuse body, and the molecular formula of the moisture-proof gel is: wherein n is 2 to 3, m is 10 to 15. The moisture-proof gel wax prepared by the present invention, its main body is acrylic acid acrylamide resin, has good moisture-proof performance, its own group is similar to polyamide resin, can well protect the thermal fuse itself, and its melting point is low, It has been mostly softened during heating and heat preservation, and can flow when pressed at 80°C, and can be squeezed apart under pressure, thus ensuring the normal bonding of the thermal fuse.

Description

technical field [0001] The invention relates to the field of thermal fuses, and more specifically relates to a heat-resistant fuse and a preparation method thereof. Background technique [0002] Thermal fuse generally refers to the low-melting fiber produced by composite spinning of polyester and modified polyester, which can be melted and bonded to other fibers at a lower temperature of general polyester. [0003] When the thermal fuse is stored, it is often coated with wax on the surface of the fuse to prevent sticking, but the wax coating will affect the normal use of the thermal fuse. When the thermal fuse is used, the wax itself does not flow. If it does not decompose, it will affect the bonding strength of the thermal fuse, especially the polyamide material is easy to absorb water and get wet, so it is not easy to store. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a gel-coated ant...
