Embodiment Construction

[0046] Referring to the embodiment shown in Figure 1, this SBS modified asphalt high self-adhesive waterproof roll material includes a tire base cloth, an oil-impregnated coating layer, an isolation layer and a film layer, and the raw materials of the oil-impregnated coating layer are by weight The percentage ratio is as follows:

[0047] Alkyl bitumen 40%;

[0048] SBS adhesive 10%;

[0049] naphthenic oil 5%;

[0050] Coumarone resin 5%;

[0051] Sub-spherical silica powder 30%;

[0052] Loess powder 10%.

[0053] The alkyl asphalt is 90# or 100# alkyl asphalt, and the SBS binder can be YH-792 linear non-oil-extended SBS binder. The fineness of the sub-spherical microsilica powder and loess powder can be nano-scale, which can further improve the mixing ability of composite fillers and other raw materials, improve the extension performance of waterproof membranes, and improve the ability to prevent ultraviolet radiation and anti-aging.

Abstract

The invention relates to a high-self-adhesive waterproof roll material of SBS (Styrene-Butadiene-Styrene) modified asphalt and a production process thereof. The waterproof roll material comprises tire fabric, an oil-lubricated coating layer, a separating layer and a filming layer, wherein the oil-lubricated coating layer is prepared from the following materials in percentage by weight: 35-40 percent of alkyl asphalt, 10-13 percent of SBS binder, 3-5 percent of naphthenic oil, 5-13 percent of coumarone resin, 10-30 percent of sub-spherical silica micro powder and 10-29 percent of loess powder, wherein the sub-spherical silica micro powder and the loess powder are together used as a compound filler, and the addition of the two materials is 39-42 percent of the total material weight of the oil-lubricated coating layer. By adopting the sub-spherical silica micro powder and the loess powder as the compound filler, the invention can obviously improve the tensile strength and the elongation of the roll material, not only takes the effect of improving the adhesion, but also plays a role of resisting corrosion and radiation.

Description

technical field [0001] The invention relates to a building waterproof coiled material and a production process thereof. Background technique [0002] The existing modified asphalt self-adhesive waterproofing membrane generally contains the following components in its formula: modified asphalt, binder, plasticizer, tackifier, filler, and other additives. Due to the different formula selection and raw material addition amount of the oil-impregnated coating layer, there will be great differences in the performance of the waterproof membrane. The existing waterproof coiled material has the problems of poor extensibility and easy cracking during construction. Although the performance of the waterproof membrane using SBS material is good, the cost is high, the formula is relatively complicated, and the filler is mostly single-component calcium carbonate or wollastonite, so the adhesive performance of the membrane is greatly affected, and the elongation rate and fracture resistan...
