The stirring speed in the step c is 25 r/min.
Example two:
the nylon thermal fuse, 70D/10F thermal fuse with melting point of 85 ℃ and commercially available from Korea Daoxing company is prepared by passing the thermal fuse through the moisture-proof gel wax prepared in the first embodiment, spinning the thermal fuse into a thermal fuse cloth with the specification of aperture of 1mm, taking 10cm x 10cm thermal fuse cloth, heating the thermal fuse cloth to 60 ℃, preserving heat for 1-2 min, placing the thermal fuse cloth into two layers of 70D210T3 cellular nylon cloth commercially available from Suzhou Haabin textile Co., Ltd, heating to 80 ℃, and pressing.
Comparative example one:
the nylon thermal fuse, 70D/10F, with the melting point of 85 ℃ is purchased from Xiaoxing company of Korea, the thermal fuse is spun into thermal fuse cloth after passing through PE wax which is purchased from the market and has the limited disclosure of Suzhou Chenghai fine chemistry industry, the specification of the thermal fuse cloth is 1mm, 10cm of the thermal fuse cloth is taken, the thermal fuse cloth is firstly heated to 60 ℃ and is kept for 1-2 min, and then the thermal fuse cloth is placed into two layers of 70D210T3 lattice nylon cloth which is purchased from Suzhou Haabin textile Limited company, and is heated to 80 ℃ for pressing.
Comparative example two: a nylon thermal fuse, 70D/10F thermal fuse and a thermal fuse with the melting point of 85 ℃ are purchased from Xiaoxing company of Korea, and are woven into thermal fuse cloth, the specification of the thermal fuse cloth is 1mm, 10cm x 10cm of thermal fuse cloth is taken, the thermal fuse cloth is firstly heated to 60 ℃, the thermal fuse cloth is kept for 1-2 min, then the thermal fuse cloth is placed into two layers of 70D210T3 lattice nylon cloth purchased from Suzhou seashore textile Co., Ltd, the temperature is raised to 80 ℃, and pressing is carried out.
Is directly to
The two-layer adhesive nylon cloth prepared in example two, comparative example one and comparative example two was subjected to peel strength test according to GB 11402-89:
in the above examples and comparative examples, in the second example, the self-made moisture-proof gel wax in the technical scheme of the invention is used for coating, and when a peel strength test is performed, the peel strength of the self-made moisture-proof gel wax is obviously greater than that of a hot melt adhesive coated with PE wax.
The PE wax acts as a common wax on the market, can protect the outer surface of the fiber, prevents the thermal fuse fibers from being mutually adhered, but the structure is relatively stable, when the thermal fuse is used as a common fuse, the thermal fuse can be effectively protected, but when the thermal fuse is used on a thermal fuse, the moisture-proof gel wax prepared by the invention can affect the adhesion between the adhesion body of the thermal fuse and other two layers of cloth if the moisture-proof gel wax is not removed in the pressing and ironing process of the thermal fuse, the body of the thermal fuse is acrylic acid acrylamide resin, has better moisture resistance, has groups similar to polyamide resin, can well protect the thermal fuse, has lower melting point, most of the hot melt adhesive is softened during heating and heat preservation, and the hot melt adhesive can flow and be extruded under the action of pressure when being pressed at 80 ℃, so that the normal adhesion of the hot melt adhesive is ensured. This can be seen from comparative example two, which is almost close to the peel strength of a thermal fuse without wax coating.
