The self-adhesive waterproof coiled material of strong cross laminated film is a high-performance cold-construction non-padding waterproof coiled material. The self-adhesive waterproof coiled material takes synthetic rubber, asphalt, tackifier and anti-aging agent as base materials and anti-adhesive isolation paper/film as an isolation layer, and has the characteristics of tearing resistance, stable size and the like. The prior art has certain disadvantages. Firstly, the single-layer PE film self-adhesive rubber asphalt waterproof coiled material has the defects of poor water seepage resistance, low tensile strength and poor weather resistance, and has the problems of unsynchronized longitudinal and transverse performance indexes, hollowing, wrinkling and the like.

The main waterproof object of the building is concrete, excessive water except hydration is volatilized in the hydration process of cement, shrinkage and creep of the concrete can cause the concrete to form a little tiny capillary holes or visible small holes, and when a base layer is greatly settled or a main structure is greatly deformed, asphalt sizing materials are likely to be peeled from the main structure to reduce the waterproof effect, so that the hidden danger of water leakage exists.

In a second aspect, the present application provides a method for preparing a roll of a strong cross-laminated film double-sided self-adhesive waterproofing material as described in any one of the above, said method comprising the following steps:
(1) heating mullite sand at 105 ℃ for 2.5h, adding isobutyltriethoxysilane in a set proportion into a mixer for modification, wherein the modification temperature is 120 ℃, the modification time is 50min, and cooling to obtain isobutyltriethoxysilane-modified mullite sand;

(6) shaping, cooling, rolling and plastic packaging.
The beneficial effects of the invention include:
firstly, mullite sand subjected to high-temperature treatment is used as a material, white siliceous sand grains are used for blocking and reflecting ultraviolet rays, radiation of the mullite sand grains to the surface of self-adhesive glue is blocked, the surface viscosity of the mullite sand is kept, the cohesiveness of the mullite sand and cement concrete is not influenced, and people can stand on the mullite sand after the mullite sand is paved. Meanwhile, after the mullite sand is modified, the small molecular structure of the isobutyl triethoxy silane can penetrate through the cementitious surface and penetrate into the concrete to chemically react with air exposed in an acidic or alkaline environment and water molecules in the substrate to form a water repellent treatment layer, so that water is inhibited from entering the substrate, and the mullite sand has waterproof, Cl-proof and ultraviolet-resistant performances and has air permeability. Can effectively prevent the base material from corroding, loosening, stripping and mildewing the concrete and the internal steel bar structure due to the corrosion of water seepage, sunshine, acid rain and the like, thereby prolonging the service life of the building. The protected substrate has good water repellency and retains its original appearance. An alkaline environment, such as concrete soon as it is poured, stimulates this reaction and accelerates the formation of a water repellent layer.
Secondly, the self-adhesive waterproof roll with the strong cross laminated film provided by the invention selects the strong cross laminated film, and adopts a mode of laminating, hot-pressing and compounding three layers of high-density polyethylene films with an included angle of 60 degrees. Compared with the preparation method of the prior art, the preparation method has the advantages that the molecular stretching directions of the three layers of high-density polyethylene films form an angle of 60 degrees with each other, and the stress directions form a triangular structure, so that the strong cross laminated film self-adhesive waterproof roll prepared by the invention has excellent tensile property in all directions, has better adaptability to use environments, and is particularly suitable for positions such as internal and external corners.
And thirdly, adding a hydroxyl active substance in a proper proportion into the modified asphalt-based adhesive film. Hydroxyethyl cellulose plays the effect of tackification, dilatation, plastification, promotes waterproofing membrane's creep nature and self-healing nature greatly, has good parcel effect to sharp-pointed object, meets tiny destruction and crack in the construction, but automatic shutoff healing. Meanwhile, active hydroxyl contained in the hydroxyethyl cellulose and the nano silicon dioxide can be chemically reacted with cement in the curing process to form chemical bonding force, the waterproof roll and the post-cast concrete are chemically cross-linked and physically mortise and tenon, and the waterproof roll and the post-cast concrete are tightly combined together to form a skin type waterproof layer, so that high-strength and permanent bonding is achieved, and water channeling can be completely prevented. Meanwhile, experiments show that the two can achieve the most excellent effect by being compounded and used according to a certain proportion.
And fourthly, nano alumina modified by surface dispersion is added into the non-asphalt-based self-adhesive, and the alumina can be uniformly dispersed in the adhesive. The nano-alumina has extremely high strength and good toughness, and the product has higher activity in the cement hydration reaction, so that the performance of concrete can be effectively enhanced, and the adhesion of self-adhesive and post-cast concrete can be effectively enhanced. Meanwhile, the aluminum oxide has better flame retardance and can improve the flammability of the high-density polyethylene cross laminated film layer to a certain extent.
