Problems solved by technology

[0002] With the development of the industrial industry, tapes are widely used in electronics, computers, home appliances and other fields. Tapes are widely used in various fields because of their good bonding performance, and the stickiness of tapes is an important indicator of tape quality. People pay attention , but in many tape applications, the functional matching of the tape is not perfect
At present, there are few varieties of flame-retardant tapes, and the relative demand for applications varies greatly. Moreover, the existing flame-retardant tapes do not have good sealing performance, and will quickly lose their viscosity when the temperature is high, resulting in tape failure and easy to cause serious losses.

Embodiment 1

[0032] Such as figure 1 Shown, a kind of high-sealing composite multifunctional adhesive tape, comprises:

[0033] Sealing adhesive layer 3; fireproof layer, the fireproof layer comprises: the heat insulation layer 4 that is bonded on the top of the sealing adhesive layer 3, the flame retardant layer 5 that is bonded on the top of the heat insulation layer 4, and the fire retardant layer 5 is bonded with Aluminum foil substrate 6; and, the release layer 1 attached under the sealing adhesive layer 3; where above the release layer 1 is provided with several strip-shaped protrusions 2, and the strip-shaped protrusions 2 are not connected to each other.

[0034] Wherein, the sealing adhesive layer 3 includes the following components and contents: 22 parts of plasticizers, 30 parts of silicone rubber, 8 parts of inert fillers, 8 parts of antioxidants, 22 parts of tackifying resins, the above-mentioned contents are increased by weight. Plasticizers are 1,5-diazido-3-oxapentane, 1,8...

Embodiment 2

[0042]The difference between this embodiment and Embodiment 1 is that the sealing adhesive layer 3 includes the following components and contents: 32 parts of plasticizer, 40 parts of silicone rubber, 15 parts of inert filler, 18 parts of antioxidant, tackifying resin 32 parts, the above-mentioned content is by weight, the plasticizer is preferably a mixture of 1,5-diazido-3-oxapentane and tricresyl phosphate TCP, and the mass number is: 1,5-diazide 30 parts of base-3-oxapentane, 70 parts of tricresyl phosphate TCP, the silicone rubber is preferably silicon boron rubber, and the inert filler is a combination of montmorillonite and lignin rubber reinforcing agent. The mass number is: montmorillonite 50 parts of soil, 30 parts of lignin-type rubber reinforcing agent, the antioxidant is preferably thiobisphenol, the tackifying resin is preferably a mixture of coumarone-indene resin and hydrogenated C5 petroleum resin, by mass: ancient 60 parts of Malone-indene resin, 30 parts of ...

Abstract

The invention relates to a composite multifunctional adhesive tape with high sealing performance. The composite multifunctional adhesive tape comprises a sealing bonding layer, the fireproof layer comprises a heat insulation layer bonded to the upper portion of the sealing bonding layer and a flame-retardant layer bonded to the upper portion of the heat insulation layer, and an aluminum foil base material is bonded to the upper portion of the flame-retardant layer; the release layer is adhered to the lower part of the sealing and bonding layer; wherein a plurality of strip-shaped bulges are arranged above the release layer, the strip-shaped bulges are not communicated with one another, and the bulges are coated with a mixture of lithium powder and a drying agent for absorbing moisture. By means of the arrangement, the adhesive tape has good sealing performance, can still maintain high viscidity under the high-temperature condition and has the advantage of being high in reliability, and the aluminum foil base material enables the surface of the adhesive tape to be easy to clean, excellent in flame retardant performance and good in corrosion resistance, puncture resistance and energy absorption. The flame-retardant layer and the heat insulation layer are matched to reduce the influence of short-time high temperature on the bonding performance of the sealing bonding layer, and the bonding capacity is guaranteed.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a high-sealing composite multifunctional adhesive tape. Background technique [0002] With the development of the industrial industry, tapes are widely used in electronics, computers, home appliances and other fields. Tapes are widely used in various fields because of their good bonding performance, and the stickiness of tapes is an important indicator of tape quality. People pay attention , but in many tape applications, the functional matching of the tape is not perfect. At present, there are few varieties of flame-retardant tapes, and there is a large gap in relative application requirements. Moreover, the existing flame-retardant tapes do not have good sealing performance, and will quickly lose their viscosity at high temperatures, resulting in failure of the tape and causing serious losses. Contents of the invention [0003] In order to solve the above-mentioned te...
