Thermal insulation elastomer modified asphalt coating as well as preparation method and waterproof coil thereof

Abstract

The invention relates to the field of building waterproof materials, in particular to a thermal insulation elastomer modified asphalt coating as well as a preparation method and a waterproof coil thereof. The thermal insulation elastomer modified asphalt coating is characterized by being prepared from the following raw materials in parts by mass: 40-70 parts of natural asphalt, 2-12 parts of a softener, 0.1-5 parts of graphene aerogel, 3-10 parts of SBS, 1-6 parts of plastics and 10-40 parts of a filler. The thermal insulation elastomer modified asphalt coating and the waterproof coil have thebeneficial effects that the thermal insulation elastomer modified asphalt coating and the waterproof coil have thermal insulation performance, the modified asphalt waterproof coil is endowed with thethermal insulation function without influencing the waterproof performance of the modified asphalt waterproof coil, and an application range of the building waterproof materials is expanded.

Description

technical field [0001] The invention relates to the field of building thermal insulation and waterproof materials, in particular to a thermal insulation elastomer modified asphalt coating material, a preparation method thereof, and a waterproof coiled material. Background technique [0002] Elastomer (SBS) modified asphalt waterproofing membrane is widely used in roofs, vertical walls and other parts of buildings because of its excellent performance, simple manufacturing process, mature construction methods, and low cost compared with other waterproof materials. Modified asphalt waterproofing The structure of the coil is generally polyester tire, glass fiber tire, glass fiber reinforced polyester tire, etc. The coating overlies the release material. [0003] Graphene airgel is the lightest solid material known in the world. It has many pores inside and is filled with air. Its elasticity and oil absorption ability are surprising. The preparation method is simple. The large s...

Problems solved by technology

[0004] With the development of buildings, waterproof and thermal insulation functions have become the basic requirements for roof and wall construction. The traditional construction method is to set waterproof and thermal insulation layers on the roof and wall, so that from materials to construction, whether it is waterproof or thermal insulation, They are all independent and single in function, lacking overall consideration. There are three disadvantages: first, the complementarity between waterproof materials and thermal insulation materials is poor, and the waterproof and thermal insulation performance is reduced; second, once the waterproof layer leaks, the thermal insulation layer loses its thermal insulation function immediately , The third is to divide the construction into two times, the cost is relatively expensive, and the thermal insulation function is added to the SBS modified asphalt waterproof membrane with excellent waterproof effect, without affecting its own waterproof effect and performance, and it is made into an integrated thermal insulation Thermal and waterproof membrane in one, an economically viable approach

[0005] China CN106313815A discloses a kind of SBS modified asphalt thermal insulation and waterproof coiled material, its thermal insulation and waterproof principle is to be respectively provided with the thermal insulation layer that SBS modified asphalt layer, polyethylene waterproof layer and polyurethane material are made in coiled material, but this will Insulation materials and waterproof materials are used in parallel. The polyurethane insulation layer is a non-hydrophobic material, and the complementarity between the two is poor. In addition, an insulation layer and a waterproof layer are provided in the coil, which will make the surface difficult to bond, resulting in a decrease in waterproof and insulation performance. Unable to achieve ideal application effect
