The waterproof adhesive tape provided by the invention comprises three parts, namely a plastic strip layer, a self-adhesive strip layer and a release layer in sequence. Wherein the self-adhesive tape layer is the key point of the invention.
SEBS (Styrene-Ethylene-Butylene-Styrene block copolymer) is a linear triblock copolymer which takes polystyrene as a terminal segment and takes an Ethylene-Butylene copolymer obtained by hydrogenation of polybutadiene as a middle elastic block, and is called Styrene Ethylene Styrene in English, and is called SEBS for short. SEBS does not contain unsaturated double bonds, so the SEBS has good stability and aging resistance.
The SEBS selected in the invention is a high molecular weight linear SEBS with the styrene content of 30 percent and the molecular weight of 22 ten thousand.
The hydrogenated C6-20-hydrocarbon polymer has the formula (C)45H78)nN is 10 to 1000, CAS registry 69430-35-9, and foreign language name POLY (METHYLSTYRENE-CO-INDENE).
The polymers of hydrogenated C6-20-hydrocarbons having a softening point of 96 to 105 ℃ are selected for use in the present invention.
According to the adhesive tape layer of the waterproof adhesive tape, SEBS is used as a main body of the adhesive tape, and a hydrogenated C6-20-hydrocarbon polymer is added into the SEBS to prepare a colloid; the SEBS can be mainly used as a toughening agent, so that the waterproof adhesive tape has certain tensile strength, the hydrogenated C6-20-hydrocarbon polymer provides excellent surface viscosity for the adhesive tape, the adhesive tape can be tightly adhered to a table top, the adhesive tape has excellent waterproof effect under the combined action of the adhesive tape and the hydrogenated C6-20-hydrocarbon polymer, the toughness of the adhesive tape is greatly improved, the cohesion is better, and the adhesive tape has excellent tear resistance. The polyvinyl alcohol fibers can further enhance the tear resistance of the self-adhesive tape. The adhesive tape prepared by the SEBS, the hydrogenated C6-20-hydrocarbon polymer and the polyvinyl alcohol fiber has the advantages of good waterproof effect, excellent surface viscosity, good shear strength and peel strength, strong cohesion and tear resistance, outstanding excellent performance and no cement residue during dismantling.
Furthermore, the SEBS accounts for 10-15 parts by weight, the hydrogenated C6-20-hydrocarbon polymer accounts for 10-20 parts by weight, and the polyvinyl alcohol fiber accounts for 1-3 parts by weight.
Experiments prove that the performance of the self-adhesive tape can be further improved by selecting proper SEBS, hydrogenated C6-20-hydrocarbon polymer and polyvinyl alcohol fiber content.

The results are shown in Table 1.
TABLE 1 analysis of Performance test results for different tapes
As can be seen from table 1, the waterproof tapes prepared in comparative examples 1, 2, 3 and 4, like example 2, contain no SEBS, and the prepared tapes have a large amount of residual daub when being removed, reduced shear strength and peel strength, poor waterproof effect and water leakage phenomenon; as in example 3, without the hydrogenated C6-20-hydrocarbon polymer, the resulting tape had very low shear and peel strength, almost no tack, resulting in severe water leakage during the water resistance test; as in example 4, without polyvinyl alcohol fibers, the cohesive force of the tape was low, and the shear strength and peel strength were significantly reduced, resulting in a small amount of residual cement upon removal; the waterproof adhesive tape prepared in example 1, when containing both SEBS, hydrogenated C6-20-hydrocarbon polymer and polyvinyl alcohol fiber, surprisingly found that the two can supplement each other and have a remarkable synergistic effect, and the prepared colloid has good toughness and cohesion, so that the shear strength and peel strength are high, and the softness is proper, therefore, the whole adhesive tape can be pulled up when being removed, and no mark is left on the tile.
In comparative examples 1, 5, 6 and 7, as in example 5, when the SEBS and the polyvinyl alcohol fibers were not contained, the adhesive tape had poor cohesion and extremely poor toughness, and even cracked, the shear strength and the peel strength were significantly reduced, and a large amount of residual daub occurred during removal; as in example 6, without the SEBS and hydrogenated C6-20 hydrocarbon polymer, the resulting tape had very low shear and peel strength, almost no tack, severe water leakage during the water resistance test, and a large amount of residual mastic upon removal; as in example 7, the polymer containing no hydrogenated C6-20 hydrocarbon and the polyvinyl alcohol fiber showed a significant decrease in shear strength and peel strength, and severe water leakage in the water resistance test and a large amount of cement residue on removal.
The SEBS, the hydrogenated C6-20-hydrocarbon polymer and the polyvinyl alcohol fiber are all indispensable, and the SEBS, the hydrogenated C6-20-hydrocarbon polymer and the polyvinyl alcohol fiber are compounded together to obtain the product which has excellent performance meeting the public requirements, good waterproof effect and can still be removed without traces after long-term use.
In comparative examples 1, 8, 9 and 10, as in example 8, when SEBS is replaced with SEPS having a similar performance to SEBS, since SEPS has a shorter methyl unit series in structure compared to ESBS, when SEPS is combined with a polymer of hydrogenated C6-20-hydrocarbon and polyvinyl alcohol fiber, it is difficult to exert a good synergistic effect, the cohesive strength of the prepared adhesive tape is low, a small amount of residual daub remains during removal, and the waterproof effect is also poor; as in example 9, when the SEBS, C5 petroleum resin and polyvinyl alcohol fiber are used to prepare the adhesive tape, a large amount of cement remains when the adhesive tape is removed, and the adhesive tape has poor stability, is easy to yellow, has poor waterproof effect, and has a small amount of leakage; as in example 10, the combination of SEBS, hydrogenated C6-20 hydrocarbon polymer and polyester fibers used to prepare the tape also failed to achieve good waterproofing performance, a small amount of cement remained after removal, and the shear strength and peel strength of the tape were significantly reduced. Therefore, the SEBS, the hydrogenated C6-20-hydrocarbon polymer and the polyvinyl alcohol fiber are most preferably adopted to prepare the adhesive tape, the adhesive tape has outstanding excellent performance, no cement residue is generated during removal, and the design requirements are met.
Comparative examples 1, 11 and 12, like example 11, without EVA, produced tapes with rough and bright surfaces; therefore, the EVA plays a role in enabling the surface of the adhesive tape to be bright and fine in the system; as in example 12, the absence of white oil also affected the performance of the tape, and a small amount of residue appeared upon removal, and the shear strength and peel strength of the tape were also reduced.
Comparing the waterproof tapes of example 1 and the two kinds of kitchen and bathroom tapes on the market, the two kinds of tapes have waterproof functions, but have the problems of daub residue during dismantling, low shear strength and peeling strength of the tapes and yellowing of the sample B; the waterproof adhesive tape provided by the embodiment 1 has good waterproof performance, and can not leave any cement mark on a table top when being removed.
EXAMPLE 14 Effect of different amounts of Components on the preparation of Water resistant adhesive tapes
In this example, the method for preparing the waterproof tape provided in example 1 was used, wherein the contents of the components were different, and the total content was five groups, and the content of each group is specifically shown in table 2.
TABLE 2 different contents of the components of the waterproof tape
And (4) inspecting the appearance, the water resistance, the shear strength and the peel strength of the five groups of samples, and removing the samples to obtain residual daub. The investigation method comprises the following steps: (1) the appearance detection method comprises the following steps: and tearing the release paper of the adhesive tape, observing whether the surface of the adhesive tape is bright and fine, and recording the result. (2) The waterproof property detection method comprises the following steps: a 30 cm-30 cm open water tank self-made by ceramic tiles is used, and gaps with the width of 1-2mm and the length of about 10cm are reserved at the side surface and the bottom of the water tank and are used for testing the waterproof performance of the adhesive tape; and (3) sticking the gap at the bottom of the water tank by using an adhesive tape, filling the water tank with water, observing whether water seeps from the gap after 24 hours, and recording the result. (3) The shear strength is detected by sample preparation according to GB/T7124-2008; the peel strength is detected by sample preparation according to GB/T13477.18-2002; (4) the method for detecting the residual daub after dismantling comprises the following steps: and removing the release paper from the adhesive tape, attaching the adhesive tape to the glazed surface of the ceramic tile, standing for 3 months at the temperature of 23 +/-2 ℃, peeling the adhesive tape from the ceramic tile at 90 degrees by hands, checking whether cement remains on the ceramic tile, and recording the result. The results are shown in Table 3.
TABLE 3 influence of different contents of the components of the waterproof adhesive tape for kitchen and bath on the detection result
As can be seen from Table 3, for example, when the materials of group 2-4, SEBS10-15, hydrogenated C6-20-hydrocarbon polymer 10-20, polyvinyl alcohol fiber 1-3, white oil 10-15, EVA10-15, talcum powder 40-50 and anti-aging agent 1-2 are used, the prepared colloid has bright and fine appearance, good waterproof performance and high shear strength and peel strength, and no cement remains on the table top during removal; however, when the components are out of the above ratio ranges, such as groups 1 and 5, the prepared colloid has poor properties and cannot meet practical applications.
Of these, the most preferable is group 3, which is the most preferable combination, in which 12 parts of SEBS, 14 parts of a hydrogenated C6-20-hydrocarbon polymer, 2 parts of polyvinyl alcohol fiber, 13 parts of white oil, 13 parts of EVA, 45 parts of talc powder, and 1 part of an antioxidant are used, and both the shear strength and the peel strength are the highest.

The method for detecting the bonding strength between the adhesive tape and the plastic strip comprises the following steps: adhering two plastic strips together by using cement (the two plastic strips clamp the cement), pressing, standing for 24 hours at normal temperature, peeling the two plastic strips by using a tension tractor, and detecting the maximum peeling strength of the two plastic strips; other detection methods are shown in example 14. The results are shown in Table 4.
TABLE 4 Effect of Using different Plastic strips on the preparation of Water-resistant tapes
As can be seen from Table 4, compared with the PET plastic strip, the adhesive tape provided by the invention is more firmly adhered to the PVC plastic strip, and the adhesive strength of the adhesive tape is obviously higher than the shear strength and the peel strength of the adhesive tape, so that the situation that the plastic strip is also peeled during the removal, the plastic strip is difficult to continuously remove is avoided, and the traceless removal is easier to realize.
