In the description herein, when a composition is described as containing, comprising, or including a particular component, or when a process is described as containing, comprising, or including a particular process step, it is contemplated that the composition of the present application also consists essentially of, or consists of, the component, and that the process of the present application also consists essentially of, or consists of, the process step.
The use of the terms "comprising," "including," "containing," and "having" are generally to be construed as open-ended and non-limiting unless otherwise expressly specified.
In the description herein, it is to be noted that, unless otherwise specified, "above" and "below" are inclusive, and "a plurality" of "one or more" means two or more.
The above summary of the present application is not intended to describe each disclosed embodiment or every implementation of the present application. The following description more particularly exemplifies illustrative embodiments. At various points throughout this application, guidance is provided through a list of embodiments that can be used in various combinations. In each instance, the list is merely a representative group and should not be construed as exhaustive.
According to the construction process of pre-laying the waterproof roll, firstly laying the waterproof roll, then pouring concrete, and the concrete can be firmly bonded with the roll. The inventor finds that after the pre-paved waterproof roll is paved, concrete needs to be poured after being left for a certain time due to the change of a construction plan because of the requirement of actual construction. In the period, because the hot-melt pressure-sensitive adhesive used in the self-adhesive layer in the prior art does not have good ultraviolet aging resistance, under the action of ultraviolet rays in sunlight, the self-adhesive layer of the pre-paved waterproof roll is easy to age and crack, so that the bonding strength is reduced, and finally, the phenomenon of layering and falling off of the pre-paved waterproof roll can be caused.
In view of the above, the application provides a hot-melt pressure-sensitive adhesive, a preparation method thereof and a pre-paved waterproof roll.
The application provides in a first aspect a hot melt pressure sensitive adhesive comprising the following raw material components in parts by weight:
Figure BDA0003173633970000051
according to the hot melt pressure sensitive adhesive of the first aspect of the present application, since the raw material thereof includes the olefin copolymer containing α -olefin, the olefin copolymer containing α -olefin has a lower degree of unsaturation compared to synthetic rubber, and photo-oxidative aging is less likely to occur due to irradiation of ultraviolet light, the hot melt pressure sensitive adhesive according to the present application has excellent ultraviolet aging resistance. In addition, the ultraviolet aging resistance of the hot melt pressure sensitive adhesive is further improved by utilizing the matching of the composite light stabilizer and the olefin copolymer containing alpha-olefin. According to the hot-melt pressure-sensitive adhesive, the hot-melt pressure-sensitive adhesive is not easy to age and crack under the action of ultraviolet rays, and can still keep better bonding strength.
In the hot melt pressure sensitive adhesive provided by the first aspect of the present application, the olefin copolymer containing α -olefin contained in the raw material is a nonpolar polymer. The conventional synthetic rubber contains carbon-carbon double bonds inside, and the two ends of the carbon-carbon double bonds are connected with different groups, so that the two carbon atom electron cloud densities are different, and finally the carbon-carbon double bonds have certain weak polarity, so that the synthetic rubber belongs to a weak polarity polymer. Conventional synthetic rubbers are poorly compatible with olefin copolymers containing alpha-olefins according to the principle of similar compatibility. If the conventional synthetic rubber is used as a raw material of the hot-melt pressure-sensitive adhesive, the cohesive strength of the hot-melt pressure-sensitive adhesive at the later use stage is weakened, and the bonding effect is poor.
The hydrogenated synthetic rubber reduces the content of the whole carbon-carbon double bonds by hydrogenating the carbon-carbon double bonds of the non-hydrogenated synthetic rubber, thereby reducing the polarity of the hydrogenated synthetic rubber and improving the compatibility of the hydrogenated synthetic rubber and the olefin copolymer containing alpha-olefin.
The hot melt pressure sensitive adhesive of the raw material comprising the hydrogenated synthetic rubber and the olefin copolymer containing alpha-olefin provided by the first aspect of the application has good compatibility with the hot melt pressure sensitive adhesive of the olefin copolymer containing alpha-olefin, and can still keep higher cohesive strength in the later period of use.
In some embodiments, the above-described olefin copolymer comprising an α -olefin may be selected from at least one of an amorphous α -olefin copolymer and a polyolefin elastomer POE.
The amorphous alpha-olefin copolymer is a random copolymer obtained by polymerizing alpha-olefin (such as ethylene, propylene, 1-butylene and the like), and has low molecular weight and high randomness.
Polyolefin elastomers POE include copolymers of C4-C8 alpha-olefins with ethylene. In some embodiments, the polyolefin elastomer POE may preferably be a polyolefin elastomer POE prepared using a metallocene catalyst.
The inventor finds that the hot-melt pressure-sensitive adhesive prepared by using the polyolefin elastomer POE prepared by using metallocene as a catalyst has excellent ultraviolet aging resistance. The polyolefin elastomer POE has narrow relative molecular mass distribution and uniform short chain branch distribution on one hand, and on the other hand, as the molecular chain is saturated and contains less tertiary carbon atoms, the polyolefin elastomer POE can be used as the raw material of the hot-melt pressure-sensitive adhesive, and can obviously improve the ultraviolet aging resistance of the hot-melt pressure-sensitive adhesive.
In some embodiments, the polyolefin elastomer POE may have a melt index of 10 to 40g/min measured at 190 ℃, under a load of 2.16kg, and with a pore diameter of 2.1 mm.
The melt index of the polyolefin elastomer POE is in a proper range, so that the impact resistance, the environmental stress cracking resistance and the chemical medium resistance of the hot-melt pressure-sensitive adhesive containing the polyolefin elastomer POE can be improved, and the performances of the hot-melt pressure-sensitive adhesive, such as breaking strength, hardness, toughness, ageing resistance stability and the like, can be improved.
In some embodiments, the amorphous α -olefin copolymer has a melt viscosity of 2000 to 100000 mPa-s (absolute viscosity) measured at 190 ℃w40000-100000, number average molecular weight MnIs 5000 to 30000.
Melt viscosity and M of amorphous alpha-olefin copolymerw、MnIn a proper range, the ultraviolet aging resistance of the hot melt pressure sensitive adhesive can be improved, and the adhesive property, strength, elasticity, toughness and abrasion resistance of the hot melt pressure sensitive adhesive can also be improved.
In some embodiments, the polyolefin elastomer POE may preferably be an ethylene-octene copolymer, and more preferably an ethylene-octene copolymer prepared by using metallocene as a catalyst.
Compared with other polyolefin elastomers POE, the ethylene-octene copolymer has more carbon atoms, longer branched chains, better tensile strength, rheological property, fast and slow cracking resistance and impact resistance, and can further improve the performances of the hot melt pressure sensitive adhesive such as breaking strength, hardness, toughness, ageing resistance stability and the like.
In some embodiments, the hot melt pressure sensitive adhesive may comprise the following raw material components by weight:
Figure BDA0003173633970000071
by adopting the raw material components in parts by weight, the hot-melt pressure-sensitive adhesive has better ultraviolet aging resistance.
In some embodiments, the weight ratio of the above-mentioned olefin copolymer containing an α -olefin to the hydrogenated synthetic rubber may be 1 (1 to 1.2).
The inventors have found that the amount ratio of the olefin copolymer containing α -olefin to the hydrogenated synthetic rubber is an important factor affecting the performance of the hot melt pressure sensitive adhesive. As the amount of the olefin copolymer containing α -olefin used relative to the hydrogenated synthetic rubber increases, the normal peel strength of the hot melt pressure sensitive adhesive decreases. On the contrary, as the amount of the alpha-olefin-containing olefin copolymer relative to the hydrogenated synthetic rubber is decreased, the peel strength of the hot melt pressure sensitive adhesive after ultraviolet aging is decreased. In order to make the hot-melt pressure-sensitive adhesive have excellent normal-state peel strength and peel strength after ultraviolet aging, the inventor selects the dosage proportion of the olefin copolymer containing alpha-olefin and hydrogenated synthetic rubber, so that the provided hot-melt pressure-sensitive adhesive has excellent service performance.
In some embodiments, the hydrogenated synthetic rubber may be selected from at least one of a hydrogenated styrene thermoplastic elastomer SEBS or a hydrogenated styrene thermoplastic elastomer SEPS.
In some embodiments, the styrene content of the hydrogenated synthetic rubber may be 10 to 30 wt%.
The polarity of the hydrogenated synthetic rubber increases with the styrene content, and the resistance to thermo-oxidative ageing increases with the styrene content. The inventor selects hydrogenated synthetic rubber with the styrene content of 10-30 wt%, and can ensure the compatibility of the hydrogenated synthetic rubber and an olefin copolymer containing alpha-olefin and simultaneously give consideration to the thermal oxidation aging resistance of the hot-melt pressure-sensitive adhesive.
In some embodiments, the plasticizer may be at least one selected from the group consisting of paraffin oil, aromatic oil, and naphthenic oil, preferably naphthenic oil.
The naphthenic oil is further preferably prepared by a three-stage high-pressure hydrogenation process. Compared with the conventional naphthenic oil containing partially hydrogenated unsaturated aromatic hydrocarbon, the naphthenic oil prepared by the three-section high-pressure hydrogenation process has the advantages that unsaturated bonds of non-hydrocarbon compounds are deeply removed, and the ultraviolet aging resistance is more excellent. The naphthenic oil prepared by the three-stage high-pressure hydrogenation process is used as a raw material of the hot-melt pressure-sensitive adhesive, and the ultraviolet aging resistance of the hot-melt pressure-sensitive adhesive can be further improved.
In some embodiments, the naphthenic oil may be further preferably a cramaezkinh-series naphthenic oil product.
In some embodiments, the tackifying resin may be selected from at least one of C5 petroleum resin, C5 hydrogenated petroleum resin, C9 hydrogenated petroleum resin, C9 hot polymerized petroleum resin, C9 cold polymerized petroleum resin, rosin resin, and terpene phenolic resin.

It will be readily understood that the above-mentioned composite light stabilizer may be selected from at least two of the same type of light stabilizer, or from at least two of different types of light stabilizers. The composite light stabilizer may preferably be a combination of at least one of a benzotriazole light stabilizer and a triazine light stabilizer with a hindered amine light stabilizer.
In some embodiments, the complex antioxidant may preferably be at least two of antioxidant 1010, antioxidant 168, antioxidant 1076, antioxidant 1726, further preferably a combination of at least one of antioxidant 1010, antioxidant 1076, or antioxidant 1726 and antioxidant 168.
In some embodiments, the composite light stabilizer may preferably be at least two of the ultraviolet absorber UV-326, the ultraviolet absorber UV-1577, the light stabilizer 770, the light stabilizer 622, further preferably a combination of at least one of the ultraviolet absorber UV-326 or the ultraviolet absorber UV-1577 and at least one of the light stabilizer 770, the light stabilizer 622.
The second aspect of the application provides a pre-paved waterproof roll, which comprises a surface anti-sticking protective layer, a self-sticking layer and a main body waterproof material layer, wherein,
the surface anti-adhesion protective layer comprises at least one of a release coating, reaction sand, quartz sand, silt and mullite sand, and the release coating is preferably at least one of an acrylate coating and a polyurethane coating.
The self-adhesive layer comprises a hot melt pressure sensitive adhesive according to any embodiment of the first aspect of the present application.
The main body waterproof material layer comprises at least one of polyethylene terephthalate, polyvinyl chloride, ethylene-vinyl acetate copolymer, ethylene copolymer modified asphalt resin, polyethylene, polypropylene and thermoplastic polyolefin.

According to the pre-paved waterproofing membrane of the second aspect of the application, even under the irradiation of ultraviolet rays, the high peeling strength can be still maintained, and the pre-paved waterproofing membrane has excellent ultraviolet aging resistance.

Test section
The pre-laid waterproof rolls in the examples 1 to 7 and the pre-laid waterproof rolls in the comparative examples 1 to 5 were subjected to a physical mechanical property test, and the test results are shown in the following table 1:
table 1 performance test table for pre-laid waterproof rolls of examples 1 to 7 and comparative examples 1 to 5

TABLE 1 continuation
Figure BDA0003173633970000131
Comparing examples 1-7 with comparative examples 1-5, it can be seen that, after the olefin copolymer containing alpha-olefin is added to the hot-melt pressure-sensitive adhesive, compared with comparative example 1, the peel strength attenuation of the pre-paved waterproof roll prepared by using the hot-melt pressure-sensitive adhesives of examples 1-7 is significantly lower. Compared with comparative examples 2-5, the pressure-sensitive adhesive prepared by the raw material components of the hot-melt pressure-sensitive adhesive in the application can be applied to pre-paved waterproof coiled materials, so that the coiled materials have better ultraviolet aging resistance. In addition, the pre-paved waterproofing membrane in the embodiment using the ethylene-octene copolymer, KNH series naphthenic oil or the composite antioxidant and composite light stabilizer which are preferred in the application has particularly outstanding ultraviolet aging resistance.
The pre-paved waterproof roll is prepared by using the hot-melt pressure-sensitive adhesive of the olefin copolymer containing the alpha-olefin as the raw material, the unsaturated degree of the olefin copolymer containing the alpha-olefin is low, and photo-oxidative aging is not easy to occur due to irradiation of ultraviolet light, so that the photo-oxidative aging degree of the self-adhesive layer of the pre-paved waterproof roll is greatly reduced, and the phenomenon that the peeling strength is greatly reduced after the ultraviolet aging of the self-adhesive layer of the pre-paved waterproof roll is reduced.
According to the embodiment 1-7, the hot-melt pressure-sensitive adhesive and the pre-paved waterproof roll have excellent ultraviolet aging resistance. Particularly, the ethylene-octene copolymer, SEBS and/or SEPS and the highly hydrogenated KNH series naphthenic oil are adopted, so that the reduction of the peeling strength of the self-adhesive layer of the pre-paved waterproof roll after ultraviolet aging can be reduced to a greater extent.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
