Embodiment 1

[0038] Weigh 15 parts by weight of naphthenic oil KN4010, 50 parts by weight of C5 petroleum resin, 2 parts by weight of nano-calcium powder, 0.2 parts by weight of antioxidant 1010, and 0.6 parts by weight of ultraviolet absorber UV-327, and add them to the reaction kettle, start Heating, the temperature is controlled at 170°C, and at the same time, the stirrer is turned on for stirring. After the above materials are all melted, add 35 parts by weight of thermoplastic elastomer SIS, 5 parts by weight of methyl methacrylate grafted SBS, keep the temperature at 180°C, and keep stirring at 170°C for 1.5 hours after all the materials are melted. The above-mentioned polymer self-adhesive that has been reacted is coated on the linear low-density polyethylene waterproof layer, extruded and thermally compounded at 100°C, shaped, and rolled to form a polymer self-adhesive waterproof membrane.

Embodiment 2

[0040] Weigh 10 parts by weight of naphthenic oil KN4020, 45 parts by weight of C9 petroleum resin, 1.5 parts by weight of rutile titanium dioxide, 0.15 parts by weight of antioxidant 1010, and 0.5 parts by weight of ultraviolet absorber UV-327, and add them to the reaction kettle. Heating, the temperature is controlled at 170°C, and at the same time, the stirrer is turned on for stirring. After the above materials are all melted, add 40 parts by weight of thermoplastic elastomer SBS, 10 parts by weight of methyl methacrylate grafted SBS, and keep the temperature at 175°C. After all the materials are melted, keep warm at 160°C and continue stirring for 1.0h. Coat the above-mentioned polymer self-adhesive that has been reacted on the EVA waterproof layer, carry out extrusion thermal compounding at 100°C, shape, and roll to make a polymer self-adhesive waterproof membrane.

Embodiment 3

[0042] Take 12 parts by weight of white oil 7#, 55 parts by weight of carbon five petroleum resin, 3 parts by weight of talcum powder, 0.5 parts by weight of antioxidant 1076, and 1.0 parts by weight of ultraviolet absorber UV-327 according to the formula and add them to the reactor, and start heating , the temperature is controlled at 175° C., and the stirrer is started to stir at the same time. After the above materials are all melted, add 55 parts by weight of thermoplastic elastomer SIS, 15 parts by weight of methyl methacrylate grafted SBS, keep the temperature at 185°C, and keep stirring at 165°C for 1.0h after all the materials are melted. The above-mentioned polymer self-adhesive that has been reacted is coated on the linear low-density polyethylene waterproof layer, extruded and thermally compounded at 90°C, shaped, and rolled to form a polymer self-adhesive waterproof membrane.

Abstract

The invention belongs to the technical field of waterproof materials for buildings, and in particular discloses a reaction type macromolecular self-adhering waterproof coiled material and a preparation method thereof. The invention comprises the main technical schemes that the waterproof coiled material consists of a surface waterproof layer, an intermediate macromolecular self-adhering layer and a bottom isolating layer, wherein the surface waterproof layer serves as a low-density polyethylene waterproof plate or an EVA plate; the intermediate layer serves as a macromolecular self-adhering layer; the chemical crosslinking reaction on an active group and concrete is carried out, and spatial three-dimensional cross-linked network is formed by the active group and a concrete interface, thereby greatly increasing the water channeling property and the durability of the waterproof coiled material are greatly increased; the bottom of the waterproof coiled material serves as a PET isolating film coated with silicon oil; therefore, the service life of the waterproof coiled material is as long as the service life of the building.

Description

technical field [0001] The invention relates to the technical field of waterproof materials for buildings, in particular, it is a reactive polymer self-adhesive with self-healing function that is applied to projects such as water conservancy and hydropower, tunnel subways, civil air defense fortifications, and underground buildings. Waterproof membrane and preparation method thereof. Background technique [0002] The biggest obstacle in the use of waterproof membranes is the bonding problem with the base surface. If the adhesion to the base surface is not strong, the waterproof membranes will fail. Therefore, various forms of self-adhesive waterproof membranes should be used. And born. The main self-adhesive waterproofing membrane currently on the market is a modified asphalt-based waterproofing membrane. This kind of waterproof membrane has low strength, there are gaps between the membrane and the concrete, and the adhesion is small, because the adhesion between the modif...
