Description
Technical Field
The invention belongs to the field of high-viscosity adhesive tapes, relates to a high-viscosity butyl adhesive tape, and in particular relates to a high-viscosity butyl adhesive tape capable of hanging weights at an ultra-room temperature.
Background
With the development and improvement of the scientific, technical and economic levels, more and more materials are discovered and new application scenes are developed. Thus, industrial products are required to be continuously new, and many new demands are also created. Of these, high-tack tape is an example.
The base materials for producing the adhesive tape can be various, such as natural rubber, synthetic rubber, polyurethane, epoxy resin, etc. Among them, styrene-butadiene rubber, butyl rubber, silicone rubber and modified varieties thereof can be used as the synthetic rubber.
In order to manufacture the adhesive tape finished product with near performance such as super room temperature of 95+/-5 ℃, aging resistance, excellent sealing performance and the like. Compared with butyl rubber adhesive tape, silicone rubber and modified varieties thereof, the adhesive tape manufactured by polyurethane and epoxy resin has higher cost; however, natural rubber and other synthetic rubbers are not significantly better than butyl rubber in terms of performance and cost, and especially can age rapidly at higher temperatures for a long period of time, and are inferior in sealing performance to butyl rubber. Therefore, butyl rubber and its modified polymer are generally selected for non-high temperature (less than 180 ℃) adhesive tape products which are required to have long-term aging resistance and excellent sealing property.

Detailed Description
The embodiments of the present application will be further described below by way of the embodiments.
The invention provides a high-viscosity butyl tape capable of hanging heavy objects at an ultra-room temperature.
According to the invention, on the premise of not reducing the adhesive force, the adhesive force of the mixture is increased, so that the bond length, bond energy and variation and displacement among molecular chain segments are reduced, and the Tg of the mixture is improved as much as possible, thereby realizing the low displacement of the butyl adhesive tape under the working condition, and reducing the displacement of the adhesive tape without adopting a chemical mode of crosslinking and curing. The adhesive capability of the high-viscosity butyl tape in the environment of 95+/-5 ℃ is ensured.
In one embodiment of the present invention, the butyl rubber is preferably IIR532 or a similar molecular weight butyl rubber.

comparative example 1
The comparative example provides a high-viscosity butyl tape which can be used at a super room temperature and can be hung with heavy objects, wherein the high-viscosity butyl tape comprises the following raw materials in parts by weight:
the adhesive properties of the high-tack butyl tapes provided in examples 1-7 in an environment of 95.+ -. 5 ℃ were tested by: placing the high-viscosity butyl adhesive tape in an environment with the temperature of 95+/-5 ℃, pasting films (nylon 66) on two sides of the high-viscosity butyl adhesive tape, fixing one side of the high-viscosity butyl adhesive tape, hanging the other side of the high-viscosity butyl adhesive tape with a weight of not more than 150g, pasting for more than 3 hours, and measuring whether the relative displacement of the films on the two sides is less than 2mm.
The high tack butyl tapes provided in examples 1-7 were tested for initial tack by the following method: the peak force value recorded by the annular initial viscosity tester is the viscosity value of the sample.
The test results of the above two tests are shown in table 1.
TABLE 1
As can be seen from table 1, the adhesive performance of comparative example 1 in an environment of 95±5 ℃ cannot reach the test result, which is mainly because paraffin oil 2280 as a plasticizer increases the molecular chain spacing and increases the slip ability of the mixture; at the same time, the glass transition temperature of the mixture is shifted to the low temperature direction, and the thermal performance of the mixture is reduced.
The applicant states that the detailed process equipment and process flows of the present invention are described by the above examples, but the present invention is not limited to, i.e., does not mean that the present invention must be practiced in dependence upon, the above detailed process equipment and process flows. It should be apparent to those skilled in the art that any modification of the present invention, equivalent substitution of raw materials for the product of the present invention, addition of auxiliary components, selection of specific modes, etc., falls within the scope of the present invention and the scope of disclosure.
