AI Technical Summary

Problems solved by technology

Existing waterproof membranes still have poor tenacity and tensile properties, poor aging resistance, and short service life.
Some plastomer-modified asphalt coils have better aging resistance and longer effective working life, but are more expensive. Therefore, some concrete pavements and asphalt pavements do not have special waterproof materials. Therefore, the market urgently needs an aging-resistant membrane. Inexpensive and high-quality waterproof membrane products

Embodiment 1

[0016] The preparation method of the flexible waterproof coiled material of asphalt composite tire comprises the following steps:

[0017] 1) First mix asphalt and waste engine oil, and raise the temperature to 180°C, add rubber resin and waste rubber powder and stir for 2 hours, add woven bags and polypropylene resin, stir for 2 hours at 200°C, then add talcum powder, stir for 1 hour, control the temperature of the material at 170°C to make a modified asphalt compound;

[0018] 2) Use polyester-cotton non-woven fabric and glass fiber mesh needle-punched composite material as the base of the carcass. After the base is unfolded, the tire is put on;

[0019] 3) The product after step 2) is mounted on the tire is coated with the modified asphalt compound obtained in step 1) in the coating tank, and two coating rollers are used to coat in the coating tank. The distance between the two coating rollers is the same as the thickness of the product. To adapt, the paint tank temperatur...

Abstract

Belonging to the technical field of waterproof materials, the invention relates to an asphalt composite matrix flexible waterproof coiled material and a preparation method thereof. The asphalt composite matrix flexible waterproof coiled material is composed of an upper surface layer and a lower surface layer, a matrix body layer and a modified asphalt rubber material. The matrix body and the modified asphalt rubber material are arranged between the upper surface layer and the lower surface layer. The upper surface layer and the lower surface layer are made of a polyethylene film. The matrix body is formed by needling a polyester cotton non-woven fabric and a fiberglass gridding cloth to a composite material to form a matrix base, and then processing the matrix base. The modified asphalt rubber material is prepared by taking rubber resin as an asphalt modifier. The technological method provided by the invention is simple, utilizes waste, turns waste materials into things of value, improves the waterproof coiled material product performance, enhances product quality, greatly improves the performance of the waterproof coiled material, effectively reduces the product cost, and ensures the product reliable working life. Thus, the waterproof coiled material has obvious operability and significant practicability, thus being popular with users.

Description

technical field [0001] The invention relates to a modified asphalt waterproof coiled material, in particular to a composite plastic body modified asphalt waterproof coiled material, which belongs to the technical field of waterproof materials. Background technique [0002] Waterproof membrane is a commonly used building material in construction. In the construction of asphalt pavement, underground engineering, and water conservancy projects, waterproof membrane is of great significance to reduce leakage and withstand high water pressure. The waterproof membrane includes a flexible waterproof membrane with asphalt composite tire inside and a membrane with plastic modified asphalt inside. The existing waterproof coiled material also has poor tenacity and tensile properties, poor aging resistance and short service life. Some plastomer-modified asphalt coils have better aging resistance and longer effective working life, but are more expensive. Therefore, some concrete pavement...
