[0003] All kinds of electronic products using speaker nets are developing in the direction of thinner and thinner, and the shapes of speaker nets are becoming more and more diverse. The curved surface design has become a more commonly used design form of speaker nets. However, the current hot spots on the market The adhesion and durability of the melt adhesive tape to the curved surface are unsatisfactory and need to be improved urgently

Embodiment Construction
[0020] The present invention will be specifically introduced below in conjunction with specific embodiments.
[0021] Prepare the hot melt adhesive in embodiment 1-embodiment 3 according to the parts by weight shown in table 1:
[0022]
[0023] The proportioning by weight of table 1 embodiment 1-embodiment 3
[0024] The preparation method of the hot-melt adhesive of each embodiment is as follows: firstly, mix the epoxy resin, styrene-butadiene-styrene block copolymer and phenolic resin evenly and then knead (150-170° C.), and then mix the Add the obtained intermediate product into polyvinyl alcohol, then add glycerin drop by drop and mix evenly, finally, add zinc oxide and matting agent to the mixture at the same time, stir evenly to obtain the product hot melt adhesive.
[0025] Then, the hot melt adhesive is used to prepare the adhesive tape, and the specific process includes the following steps:
[0026] S1. Coat the glue layer on both sides of the substrate, put it ...

Abstract
The invention discloses a hot melt adhesive tape suitable for speaker grills and a preparation process thereof; the hot melt adhesive tape comprises: a base material, adhesive layers applied to two sides of the base material, and a hot melt adhesive layer spread on the adhesive layer on one side; release paper is attached to each of the hot melt adhesive layer and the adhesive layer on the other side. The hot melt adhesive tape is suitable for pasting speaker grills; the surface of the hot melt adhesive layer is normally nonstick, may provide excellent adhesion after being hot-pressed and may be firmly pasted to the concave rough surface of an electronic product, the hot melt adhesive tape has particularly good shape applicability and is particularly applicable to arc surface pasting, and the hot melt adhesive tape remains unchanged in performance during long-term use at 0-150 DEG C, with the durability significantly improved; in addition, the hot melt adhesive tape also has good reflectivity, ensuring attractive appearance and service performance.
Description
technical field [0001] The invention relates to an adhesive tape, in particular to a hot-melt adhesive tape suitable for speaker nets and a preparation process thereof; it belongs to the technical field of adhesive tapes. Background technique [0002] Speaker Mesh Hot Melt Adhesive Tape is a double-sided adhesive tape coated with pressure-sensitive adhesive in tissue paper. It has excellent adhesive force and is suitable for pasting the speaker mesh of TV, computer, car and so on. With the improvement of market requirements, the requirements for speaker nets in terms of appearance and functionality are also getting higher and higher. The hot-melt adhesive tape used to paste the speaker mesh can exert its excellent adhesive force after high-temperature hot pressing to make the speaker mesh with convex and concave surfaces firmly adhere. After being firmly adhered, the glue surface should not be shiny, so as not to damage the overall aesthetics of the product and cause poor s...
