Description
Technical Field
The invention belongs to the field of chemical materials for buildings, and particularly relates to a polyolefin pre-paved waterproof coiled material and a preparation method thereof.
Background
Currently, hot melt pressure sensitive adhesives have been widely used in polymeric pre-applied waterproofing membranes as adhesives that provide a core bonding function. Initially hot melt pressure sensitive adhesives were coated on sheets of High Density Polyethylene (HDPE). In recent years, polypropylene (or polyethylene)/ethylene propylene rubber (epdm) blend materials and Thermoplastic Polyolefin (TPO) materials are also increasingly used as main waterproof materials, and hot melt pressure sensitive adhesive is coated on the main waterproof materials to form a pre-laid waterproof roll. In order to balance the mechanical property and the hardness or improve the flame retardant property, the polyolefin pre-paved waterproof coiled material is generally filled with inorganic fillers such as calcium carbonate, magnesium hydroxide, aluminum hydroxide and the like with higher content in the preparation process. When a conventional hot melt pressure sensitive adhesive represented by a styrene block copolymer SBC is applied to a polyolefin substrate with a high filler content, two problems occur: firstly, due to the influence of the filler, the surface roughness of the polyolefin sheet is increased, and the hot melt adhesive pressure-sensitive adhesive cannot well wet the surface of the sheet to form high-strength bonding; and secondly, the inorganic filler generally has high water absorption rate, and in a humid environment or a long-term water immersion environment, water can permeate into the interface between the sheet and the hot-melt pressure-sensitive adhesive through the filler to form a water film, so that the adhesive force between the hot-melt pressure-sensitive adhesive and the sheet is further weakened. The consequence of the combined action of the two factors is that the bonding strength between the hot melt adhesive pressure-sensitive adhesive and the polyolefin sheet with high filler content is reduced, the core index of pre-paving reverse adhesion and the peeling strength of post-pouring concrete are influenced, even the separation of the sheet and the adhesive, namely the phenomenon of 'degumming', is caused, and the waterproof effect of the coiled material is seriously influenced. In addition, along with the recent improvement of the requirement of underground engineering waterproofing specifications on the durability of waterproof materials, the improvement of the adhesive force between the hot-melt pressure-sensitive adhesive and the polyolefin sheets in a high-humidity environment or a long-term water immersion environment is particularly important, and the problem that the traditional waterproof hot-melt adhesive is frequently ignored or not overcome when used on the polyolefin sheets with high filling amount is also the problem.
CN 113429894A discloses a macromolecule self-adhesive film waterproof roll material capable of being lapped underwater and a preparation method thereof, wherein the technical route is that a layer of hot melt pressure sensitive adhesive back adhesive is additionally arranged on the back surface of a macromolecule sheet layer, and is bonded with a conventional lap joint area on the front surface in an adhesive-adhesive mode; the hot-melt pressure-sensitive adhesive is modified by adding SBR, water-soluble rubber powder and an adhesion promoter, and the applied sheet is mainly polyethylene/polypropylene/POE and only contains 1-4 parts of white master batch, belonging to a low-filler system. When the modified hot-melt pressure-sensitive adhesive in the technology is applied to a sheet with high filler content (the mass fraction of polyolefin is more than or equal to 20%), the bonding strength with post-cast concrete is remarkably reduced through verification, and partial degumming phenomenon occurs.
CN 107189732A discloses a high-weather-resistance thermoplastic polyolefin waterproof coiled material hot-melt pressure-sensitive adhesive, mainly solving the technical problems of weather resistance and low-temperature adhesion, and having no attention to adhesion between the hot-melt pressure-sensitive adhesive and a polyolefin sheet under high humidity and long-term water immersion environment; in addition, in the technical route, the initiator, the cross-linking agent, the acrylate and the amorphous APAO are required to be used for modifying the SIS, then the tetrahydrophthalic anhydride is used for modifying the C5 resin, and finally the mixture is mixed, so that the process route is complex, the production efficiency is low, and the industrial application is difficult to realize.
CN 113004842A discloses a special hot-melt pressure-sensitive adhesive for HDPE waterproof rolls, which is still developed for an HDPE system, and the technical route of the special hot-melt pressure-sensitive adhesive needs to use two kinds of acrylic esters and acrylic acid to graft and modify SBS and SIS; then siloxane and silane coupling agent are introduced, and the process route is also complicated.
CN 111320955A concerns the problem that the hot melt pressure sensitive adhesive has weak bonding strength durability in the water immersion environment when being used on TPO, and discloses a waterproof coiled material hot melt pressure sensitive adhesive, the technical route is to adopt star-shaped SIS and SEBS as matrix polymers, and siloxane, SBR and styrene maleic anhydride copolymer are added.
The above examples are representative, and the technology is applied to modification of the hot melt adhesive pressure-sensitive adhesive of the waterproof roll. Overall, there are several disadvantages: firstly, the special hot-melt pressure-sensitive adhesive without polyolefin base material suitable for high filler system; secondly, all the technical routes related to the introduction of acrylate and derivative monomers thereof for free radical initiated grafting modification through an initiator relate to the problem of low grafting rate and the problem of residue of corresponding unreacted small molecular monomers in the hot melt adhesive pressure-sensitive adhesive according to the basic knowledge of polymer chemistry, and particularly for SBC block copolymers or SBR (styrene butadiene rubber) represented by SIS (styrene-butadiene-styrene) and SBS (styrene-butadiene-styrene) and the like, the SBC block copolymers or SBR pressure-sensitive adhesive has large melt viscosity, extremely low grafting reaction efficiency and difficult avoidance of residue of small molecular monomers, so that the long-term water-resistant bonding performance of the subsequent hot melt pressure-sensitive adhesive is obviously negatively influenced. Meanwhile, the process route of the grafting reaction is complex, and the method is not suitable for industrial application of the hot-melt pressure-sensitive adhesive. Introducing a technical route of a micromolecule silane coupling agent or siloxane, wherein the micromolecule has overlarge difference between the molecular structure and the chemical structure and solubility parameter of the main components of the hot melt adhesive pressure-sensitive adhesive, and has poor compatibility; in the comparative example of the invention, detailed verification is carried out, the phase separation phenomenon of the common silane coupling agent is quickly generated in mineral oil, particularly in high-viscosity systems such as SBC and SBR, silane small molecules are more easily dispersed and non-uniformly to cause local aggregation, or phase separation outwards migration failure occurs, the improvement effect on the adhesive force is poor, and meanwhile, the small molecule silane is easily subjected to self-condensation reaction at the mixing temperature (above 150 ℃) of the hot melt adhesive pressure-sensitive adhesive to cause failure.

Test example
The post-cast concrete of the polyolefin pre-laid waterproofing rolls of examples 1 to 7 and comparative examples 1 to 5 was immersed in water for 60 days, and the peel strength after immersion of the post-cast concrete of the pre-laid waterproofing roll and the peel strength after immersion of the overlapped region of the polyolefin sheet were measured, and the results are shown in table 2. And the films of examples 1 to 7 and comparative examples 1 to 5 were observed after being soaked in water.
