Problems solved by technology

[0003] The existing technology has the following defects: in the method of applying waterproof coating when the water seeps out of the nail holes, due to the insufficient strength of the coating film, when the roof vibrates, the coating at the nail holes is easy to tear and water seepage occurs; the coating is difficult to reach the required thickness; The coating has poor aging resistance and short service life
The method of pasting SBS modified asphalt self-adhesive waterproof membrane, because the steel structure roof is corrugated, the base layer is uneven, the material hardness is large, the bending ability is poor, it cannot be firmly attached to the base layer, it is easy to separate from the base layer, and the waterproof performance is poor

Embodiment 1

[0021] According to the weight ratio, put 10 parts of 10# petroleum asphalt, 21 parts of 100# petroleum asphalt, 3 parts of machine oil and 2 parts of naphthenic rubber softening oil in the batching tank, and heat it to 230 ° C during the stirring process; then add Stir 8 parts of SBS and 20 parts of butyl rubber powder at 230°C for 2 hours until the butyl rubber powder is fully dissolved and fully integrated with petroleum asphalt, then add 6 parts of terpene resin and stir for 1.5 hours, SBS That is, styrene-butadiene-styrene block copolymer; finally add 30 parts of stone powder and keep stirring at 190°C for 1 hour, then stop heating. The tire base is made of high-strength ultra-thin polyester cloth. At a temperature of 180 ° C, the prepared asphalt is evenly covered on both sides of the ultra-thin polyester cloth on the production line, and the uppermost layer of the asphalt is covered with aluminum foil. The thickness is 2mm. When pasting and constructing, the aluminum f...

Embodiment 2

[0023] According to the weight ratio, put 8 parts of 10# petroleum asphalt, 23 parts of 100# petroleum asphalt, 2 parts of machine oil and 3 parts of naphthenic rubber softening oil in the batching tank, and heat it to 240 ° C during the stirring process; then add Stir 5 parts of SBS and 22 parts of butyl rubber powder at 220°C for 2 hours until the butyl rubber powder is fully dissolved and fully integrated with petroleum asphalt, then add 7 parts of terpene resin and stir for 2 hours, SBS That is, styrene-butadiene-styrene block copolymer; finally add 30 parts of stone powder and keep stirring at 190°C for 1.5 hours, then stop heating. The tire base is made of ultra-thin polyester cloth. At a temperature of 185°C, the prepared asphalt is evenly covered on both sides of the ultra-thin polyester cloth and one side is covered with film. The uppermost layer of asphalt is covered with aluminum foil. The thickness of the waterproof membrane is 1.8mm.

Embodiment 3

[0025] According to the weight ratio, put 12 parts of 10# petroleum asphalt, 18 parts of 100# petroleum asphalt, 1 part of machine oil and 3 parts of naphthenic rubber softening oil in the batching tank, and heat it to 200 ° C during the stirring process; then add 11 parts of SBS and 18 parts of butyl rubber powder, stir at 200°C for 2 hours, until the butyl rubber powder is fully dissolved and fully blended with petroleum asphalt, then add 4 parts of terpene resin and stir for 2 hours, SBS That is, styrene-butadiene-styrene block copolymer; finally add 33 parts of stone powder and keep stirring at 190°C for 1.5 hours, then stop heating. The tire base is made of ultra-thin polyester cloth. At a temperature of 185°C, the prepared asphalt is evenly covered on both sides of the ultra-thin polyester cloth and one side is covered with film. The uppermost layer of asphalt is covered with aluminum foil. The thickness of the waterproof membrane is 1.5mm.

Abstract

The invention relates to a waterproof coiled material and a production method thereof. The waterproof coiled material comprises a matrix and an asphalt layer dip-coated on the matrix, wherein the asphalt layer comprises petroleum asphalt, machine oil, naphthenic rubber softening oil, SBS, butyl rubber powder, a terpene resin and stone flour in a certain ratio, and the waterproof coiled material is prepared through refining. The prepared waterproof coiled material has the advantages of good extensibility, high tensile strength, resistance to low temperature and high temperature, a good waterproof effect and a long service life; and the production method has the advantages of easy and convenient process, low cost and easily practicable operation.

Description

technical field [0001] The invention relates to a building coil, in particular to a waterproof coil and a production method thereof. Background technique [0002] At present, the steel structure roof is installed on the roof by mechanically fixing the roof corrugated color steel plate. Due to the wind force, the color steel roof will vibrate, causing the screws to loosen and the nail holes to expand, resulting in roof leakage. In the prior art, two methods are often used to prevent water leakage. The first method is to apply waterproof paint to the nail holes; the second method is to paste SBS modified asphalt self-adhesive waterproof membrane. [0003] The existing technology has the following defects: in the method of applying waterproof coating when water seeps out of the nail holes, due to the insufficient strength of the coating film, when the roof vibrates, the coating at the nail holes is easy to tear and water seepage occurs; the coating is difficult to reach the req...
