Embodiment 1
[0042] In this example, 3M 468 double-sided adhesive is used for base-less double-sided adhesive 2, which is a type of double-sided adhesive without base material, which is directly coated with acrylic acid glue. The color of the tape is transparent and belongs to 3M 200MP Series of adhesives, specifications: 1219MM*55M*0.13MMT, still has excellent adhesive effect, can prevent falling off and excellent waterproof performance, good processability, good temperature resistance, and good holding power; The base paper is polymer-coated waterproof kraft paper, which will not wrinkle even in high-humidity environments; it has good temperature resistance, with a long-term temperature resistance of 149°C and a short-term temperature resistance of up to 204°C. 3M 468 double-sided tape meets the requirements of ROHS regulations in terms of environmental protection, and is used for pasting of panels, metal nameplates, electrical parts, and shock-proof foam.

The invention relates to anti-explosion sponge glue for wrapping a wire rod and a manufacturing method of a sponge-wrapped wire rod. The sponge glue comprises a release film (1), a substrate-free double-sided adhesive tape (2) and a PU sponge (3) which are sequentially attached. The sponge glue further comprises a first adhesive area (11) and a second adhesive area (12) which are arranged in a separated mode. The manufacturing method of the sponge-wrapped wire rod comprises the following steps: (1) placing the wire rod on a middle glue area (21); (2) tearing off the release film on a first handle area (111) and the first adhesive area (11), and wrapping the first adhesive area (11) outside the wire rod; and (3) tearing off the release films on a second handle area (121) and the second adhesive area (12), and wrapping the second adhesive area (12) to obtain the sponge-wrapped wire rod. Compared with the prior art, the method has the advantages that the product quantity is increased, and the later repair cost is reduced.
Description
technical field [0001] The invention relates to the field of sponge glue, in particular to an explosion-proof sponge glue for wrapping wire rods and a manufacturing method for wrapping wire rods. Background technique [0002] Chemical sponges, such as polyurethane, are the most common polymer materials in life, and are widely used in the production of various "sponge" products. And elastic materials for shock absorption and anti-friction purposes, such as shoe soles, tractor tank track substrates. The production process is to mix the foaming resin, foaming aid and binder resin together, perform foaming processing, and use mechanical force to break the closed cells to obtain a foamed sponge with a density of 0.028g / cm 3 , 25% compression hardness is 1.9KPa. [0003] The composition of the sponge is mostly polyurethane, and the PU sponge mainly includes polyester and polyether types, which can be sliced or rolled, and can also be processed according to requirements, hot pr...
