Embodiment 1

[0020] An elastomer (SBS) modified asphalt waterproof membrane is prepared from the following raw materials in parts by weight:

[0021] 20 parts of 10# asphalt, 40 parts of 100# asphalt, 11 parts of engine oil, 12 parts of SBS (elastomer), 17 parts of talcum powder.

Embodiment 2

[0023] A kind of production technology of elastomer modified asphalt waterproof coiled material described in embodiment 1, comprises the following steps:

[0024] (1) Stirring of ingredients

[0025] 1. Prepare and weigh the raw materials used according to the above formula, and the raw materials should be classified and arranged neatly;

[0026] 2. After measuring 10# asphalt through the metering tank, put it into the batching tank, add engine oil when the temperature rises to 160±5°C, add elastomer SBS when the temperature rises to 180±5°C, and start the colloid mill while stirring 2. -3 times, when stirring for 80 minutes to 100 minutes, the temperature is controlled at 180-190°C. When the temperature rises to 200°C-210°C, add talcum powder and stir for half an hour. After checking that the mixing ingredients are sufficient, the temperature is controlled at this time Between 170-180 ℃, and take samples for semi-finished product testing;

[0027] In addition, after heating...

Abstract

The invention discloses an elastomer modified asphalt waterproof coiled material as well as a production technology and equipment thereof. The coiled material is prepared by the following raw materials in parts by weight: 20 parts of 10# asphalt, 40 parts of 100# asphalt, 11 parts of machine oil, 12 parts of elastomer and 17 parts of talcum powder. The technology comprises the steps of ingredient stirring, base feeding, oil dip coating, sanding, film coating, traction compaction and the like. The equipment comprises a metering tank, a batching tank, a colloid mill and an oil coating groove, wherein the oil coating groove is provided with an oil coating roll; a base unfolding device, a base overlapping machine, a base retention machine and a base dryer are sequentially arranged at an inlet end of the oil coating roll; and an oil soaking groove and a film coating device are sequentially arranged at an outlet end of the oil coating roll and connected with the oil coating roll. The coiled material has the advantages that the coiled material has simple components, is higher in property, simple and practicable in technology and easy to control; the surface of the coiled material is level and free from holes, chipped edges, gaps and pimples; mineral particles are uniform and consistent in particle size and are adhered to the surface of the coiled material tightly; and the coiled material is wide in using temperature range and aging-resistant.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to an elastomer modified asphalt waterproof coiled material and its production process and equipment, belonging to the field of waterproof coiled materials. Background technique [0002] Waterproof membrane is a commonly used building material in building construction. In underground engineering and water conservancy engineering construction, waterproof membrane is of great significance to reduce leakage and withstand high water pressure. Existing EPDM waterproof membranes have excellent performances such as high strength, high elongation, high tear strength, high and low temperature resistance, ozone resistance, and aging resistance, so they are widely used in building construction. The Chinese invention patent titled "An Elastomer-modified Asphalt Waterproofing Membrane and Its Preparation Process" and application number "CN200910304436.9" discloses an elastomer-modified asphalt wat...
