Problems solved by technology

[0003] However, due to the wide application of tapes, the performance requirements for tapes are also getting higher and higher. For example, tapes are also used in mobile phone communications and new energy vehicles. However, mobile phones and new energy vehicles will generate electricity during use. A large amount of heat, and the heat is relatively concentrated, prone to local heating. If mobile phones or new energy vehicles work in high temperature for a long time, it will not only cause damage to parts, but also may cause explosion or flammability, which greatly reduces safety. performance, therefore, it is necessary to study a phase change energy storage tape with good temperature resistance and adjustable temperature

Embodiment approach

[0025] In one embodiment, a phase change energy storage adhesive tape includes the following components by mass: 40-70 parts of acrylate pressure-sensitive resin, 0.5-2 parts of polyurethane curing agent, and 30-60 parts of modified phase-change material microcapsules.

[0026] It should be noted that the acrylate pressure-sensitive resin is used as the matrix of the phase change energy storage tape. The acrylate pressure-sensitive resin is the acrylate pressure-sensitive adhesive. The acrylate pressure-sensitive resin has excellent fullness, gloss and hardness, and Good solvent resistance and weather resistance, no discoloration or yellowing when baked at high temperature, low condensable volatile matter and mass loss rate, and no harmful gas escape, can be made into various pressure-sensitive tapes, It can facilitate the pasting of the film, which is conducive to ensuring the performance and quality of the finished phase change energy storage tape prepared in the subsequent p...

Embodiment 1

[0045] In this embodiment, the phase change energy storage tape includes the following components in parts by mass: 40 parts of acrylate pressure-sensitive resin, 0.5 part of polyurethane curing agent, 66 parts of alumina, 60 parts of modified phase change material Capsules, 26 parts of aluminum hydroxide, 3.5 parts of silane coupling agent KH792.

[0046] In this embodiment, the preparation method of the modified phase-change material microcapsules is as follows: provide a phase-change material, add an emulsifier and water to the phase-change material, and perform an emulsification reaction to obtain a phase-change material emulsion, and then Adding acid solution, adjusting the pH of the phase change material emulsion to 4 to obtain an acidic phase change material emulsion, providing capsule material and formaldehyde, stirring and mixing the capsule material and formaldehyde to obtain a premixed solution, and then adding lye , adjusting the pH of the premixed solution to 8 to...

Embodiment 2

[0051] In this embodiment, the phase change energy storage adhesive tape includes the following components in parts by mass: 5 parts of acrylate pressure-sensitive resin, 1.2 parts of polyurethane curing agent, 49.5 parts of alumina, 45 parts of modified phase change material Capsules, 21 parts of aluminum hydroxide, 2.8 parts of silane coupling agent KH792.

[0052] In this embodiment, the preparation method of the modified phase-change material microcapsules is as follows: provide a phase-change material, add an emulsifier and water to the phase-change material, and perform an emulsification reaction to obtain a phase-change material emulsion, and then Adding acid solution, adjusting the pH of the phase change material emulsion to 4.5 to obtain an acidic phase change material emulsion, providing capsule material and formaldehyde, stirring and mixing the capsule material and formaldehyde to obtain a premixed solution, and then adding lye , adjusting the pH of the premixed sol...

Abstract

The invention discloses a phase change energy storage adhesive tape, which is prepared from the following components in parts by mass: 20 to 50 parts of acrylate pressure-sensitive resin, 1 to 10 parts of polyurethane curing agent and 30 to 70 parts of modified phase change material microcapsule. By adopting the modified phase-change material microcapsule, heat can be transferred into the modified phase-change material microcapsule, heat absorption and energy storage are performed through the modified phase-change material microcapsule, and when the phase-change energy storage adhesive tape is adhered to a specific working part, such as a battery of a mobile phone or a new energy automobile, the generated heat can be quickly transferred and stored in the phase-change energy-storage adhesive tape, and excellent heat-conducting and energy-storage effects can be achieved, so that quick temperature control effects on working parts can be achieved, local hot phenomena can be avoided, damage to the working parts can be avoided, and the safety performance during use can be improved.

Description

technical field [0001] The invention relates to a tape material, in particular to a phase change energy storage tape and a preparation method thereof. Background technique [0002] Adhesive tape is a commonly used polymer material. There are many kinds of adhesive tapes, including high-temperature adhesive tape, insulating adhesive tape, double-sided adhesive tape, special adhesive tape, pressure-sensitive adhesive tape, die-cut adhesive tape, etc. Different types of adhesive tape can achieve different effects, thus To meet the production requirements of different industries, different functions are suitable for different industry needs, widely used, and bring a lot of convenience to people's lives. [0003] However, due to the wide application of tapes, the performance requirements for tapes are also getting higher and higher. For example, tapes are also used in mobile phone communications and new energy vehicles. However, mobile phones and new energy vehicles will generate...
