Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of adhesive tape, in particular to a composite environment-friendly water-based PVC wire harness adhesive tape and a preparation method thereof. BACKGROUND

[0002] The water-based PVC wire harness adhesive tape is an adhesive tape using water-based pressure-sensitive adhesive for pasting, which reduces environmental pollution by using environment-friendly materials, so that the adhesive tape has environmental protection, and the adhesive tape is pasted on the product by using water as a solvent pressure-sensitive adhesive, which is easy to lose adhesion when the pressure-sensitive adhesive contacts too much water at the adhesive layer, and the adhesive tape is easy to accumulate high temperature and be damaged when wrapping a heat-generating product.

[0003] The defects of the existing adhesive tape are:

[0004] 1. The existing technology KR101761486B1 discloses an adhesive tape, which does not have the technology of setting a waterproof structure at the edge of the adhesive tape, and when there is water droplet at the edge of the adhesive tape, water is easy to contact the adhesive layer of the adhesive tape, and the adhesive layer is easy to fail after long-time contact with water, so a composite environment-friendly water-based PVC wire harness adhesive tape capable of reducing the erosion of water at the edge of the adhesive tape to the adhesive layer of the adhesive tape is needed to solve the problem.

[0005] 2. The existing technology KR1020160099929A discloses an adhesive tape, which is easy to cause the adhesive layer of the adhesive tape to melt and lose the pasting effect when the product being pasted generates heat, and the heat is also easy to damage the adhesive tape material and the wrapped product, and people cannot have enough time to take measures, so a composite environment-friendly water-based PVC wire harness adhesive tape capable of absorbing heat at the pasting position of the adhesive tape and prolonging the speed of temperature rise is needed to solve the problem.

[0006] 3. The existing technology KR1020100042142A discloses an adhesive tape, which does not have the function of reminding people of abnormal temperature rise of the product wrapped by the adhesive tape, and people cannot be prompted when the temperature of the product wrapped by the adhesive tape rises, so that they cannot react in time to the abnormal temperature rise, and therefore a composite environment-friendly water-based PVC wire harness adhesive tape capable of prompting people in response to abnormal temperature rise of the adhesive tape is needed to solve the problem.

[0007] 4. The existing technology CN103173157A discloses a water-based masking tape and a preparation method thereof, which does not have the function of accelerating the heat at the wrapping position of the adhesive tape to quickly transfer and dissipate heat outward, and the heat at the wrapping position of the adhesive tape cannot be quickly transferred and dissipated outward, which is easy to cause damage to the wrapped product and the adhesive tape, so a composite environment-friendly water-based PVC wire harness adhesive tape capable of accelerating the heat at the wrapping position of the adhesive tape to transfer outward is needed to solve the problem.
