Embodiment 1

[0011] Embodiment 1: A composite modified asphalt waterproofing membrane, which is composed of an overlying surface layer, an underlying surface layer, an intermediate carcass layer and a modified asphalt rubber layer, and is characterized in that: the modified asphalt rubber layer has two layers, One layer is arranged between the upper covering layer and the middle carcass layer, and one layer is arranged between the lower covering layer and the middle carcass layer; the modified asphalt compound layer is composed of the following mass percentage materials:

[0012] Asphalt 50-62%, SBS synthetic rubber 8-10%, waste rubber powder 15-25%, waste engine oil 10-12%, polypropylene resin 1.5-2.5%, heavy calcium powder 3-6%.

[0013] The preparation method of the modified asphalt compound is as follows:

[0014] First raise the temperature of asphalt to 200-220°C, add waste engine oil and stir evenly to cool down to 180-190°C, then add SBS synthetic rubber and heat up to 240-250°C, a...

Abstract

The invention relates to a composite modified asphalt waterproof coiled material. The composite modified asphalt waterproof coiled material consists of an upper covering layer, a lower covering layer, a middle carcass layer and two modified asphalt sizing material layers, and is characterized in that one of the two modified asphalt sizing material layers is arranged between the upper covering layer and the middle carcass layer, and the other modified asphalt sizing material layer is arranged between the lower covering layer and the middle carcass layer; and each modified asphalt sizing material layer consists of 50 to 62 mass percent of asphalt, 8 to 10 mass percent of SBS (styrene butadiene styrene) synthetic rubber, 15 to 25 mass percent of waste rubber powder, 10 to 12 mass percent of waste oil, 1.5 to 2.5 mass percent of polypropylene resin and 3 to 6 mass percent of coarse whiting powder. The low-temperature performance of the asphalt is further improved, the sensitivity of the asphalt at low temperature is reduced, and the cyclic action of bad weather can be resisted, so that the service life of the material is prolonged, the production cost is greatly reduced, and a renewable resource namely base rubber powder can be fully utilized. The composite modified asphalt waterproof coiled material is applicable to water proofing of building layers, toilets and basements.

Description

technical field [0001] The invention belongs to the field of building material manufacturing, in particular to a composite modified asphalt waterproof coiled material. Background technique [0002] With the rapid development of the construction industry, the requirements for building waterproof materials are also increasing. The polymer modified bitumen waterproof membrane has become one of the recognized high-quality waterproof materials due to its excellent performance, but due to its high cost, to a certain extent Restricted its popularization and application. With the development of my country's automobile industry, the output of waste rubber has increased sharply, and the recycling of waste rubber has become the focus of research. Waste rubber is made into rubber powder, and rubber powder is used to make modified asphalt, but single rubber powder modified asphalt is difficult to meet the performance of waterproof materials. Contents of the invention [0003] The pur...
