According to the following formula, weigh each component for use: 6 parts of 10# asphalt, 43 parts of 90# asphalt, 8 parts of softening oil, 5 parts of rubber powder, 4 parts of SBS, 3 parts of high-density polyethylene, three parts 0.3 parts of allyl isocyanurate, 1.0 part of dicumyl peroxide, 13 parts of light calcium;

[0037] S2. Pour 10# bitumen and 90# bitumen into the batching tank, add softened oil when the temperature rises to 160±5°C, heat up to 180±5°C, and stir for 30 minutes until the mixture is uniform;

[0038] S3. Control the temperature at 180~190℃, then add the tire rubber powder, stir for 60 minutes until the mixture is uniform, turn on the colloid mill and perform the first grinding to make the rubber powder and oil completely blend in;

[0039] S4. After the first grinding is completed, add SBS, stir for 30 minutes until the mixture is un...

Embodiment 3

[0044] A preparation method of a new type of modified bitumen waterproofing membrane includes the following steps:

[0045] S1. Weigh each component according to the following formula in parts by weight: 7 parts of 10# asphalt, 45 parts of 90# asphalt, 9 parts of softening oil, 5 parts of rubber powder, 4 parts of SBS, 3 parts of high-density polyethylene, three parts 0.4 parts of allyl isocyanurate, 1.2 parts of dicumyl peroxide, 15 parts of fly ash;

[0046] S2. Pour 10# bitumen, 90# or 100# bitumen into the batching tank, add softened oil when the temperature rises to 160±5°C, heat up to 180±5°C, stir for 30 minutes until the mixture is uniform;

[0047] S3. Control the temperature at 180~190℃, then add the tire rubber powder, stir for 60 minutes until the mixture is uniform, turn on the colloid mill and perform the first grinding to make the rubber powder and oil completely blend in;

[0048] S4. After the first grinding is completed, add SBS, stir for 30 minutes until the mixture...

Abstract

The invention belongs to the technical field of building materials, and provides a novel modified asphalt waterproof coiled material. The novel modified asphalt waterproof coiled material comprises modified asphalt coating layers, a tire base layer and an isolation layer, wherein the material of the modified asphalt coating layer is modified asphalt, and the modified asphalt is prepared from the following components in parts by weight: 5-10 parts of 10# asphalt, 40-50 parts of 90# or 100# asphalt, 6-12 parts of softening oil, 4-6 parts of rubber powder, 3-5 parts of SBS, 2-4 parts of high density polyethylene, 0.2-0.6 part of triallyl isotactic cyanurate, 0.6-2 parts of dicumyl peroxide and 10-20 parts of filler. A preparation method comprises the following steps that firstly the modifiedasphalt is prepared by mixing materials and grinding twice; the modified asphalt is then coated on the upper surface and the lower surface of the tire base layer to obtain the tire base layer with themodified asphalt coating layers on both sides; and an isolation film is then coated to obtain the isolation layer, and forming by cooling is carried out to obtain the novel modified asphalt waterproof coiled material. The novel modified asphalt waterproof coiled material and the preparation method solve the problem of defects in high and low temperature resistance of elastomer modified asphalt and plastic modified asphalt waterproof coiled materials in the prior art.

Description

Technical field [0001] The invention belongs to the technical field of building materials and relates to a novel modified bitumen waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of roads, bridges, roofs, basements and other buildings that need to be waterproofed, it is necessary to pre-lay the waterproof membrane. According to its main waterproof composition, it can be divided into: asphalt There are four categories of waterproof membrane, polymer waterproof membrane, synthetic polymer waterproof and coating waterproof. Among them, modified bitumen waterproofing membrane is the most commonly used waterproofing membrane, accounting for nearly 70% of the total market. At present, there are two types of modified asphalt waterproofing membranes in China: one is elastomer modified asphalt waterproofing membrane; the other is plastic...
