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, wi

Embodiment 1

[0051] 55 parts (parts by mass, the same below) of natural lake asphalt and 7 parts of base oil were respectively added to the reactor and heated to 175 ° C, and the shear mixer was started. At a speed of 800 rpm, 2 parts of graphene airgel were slowly added to keep The temperature is 170-180°C, and the stirring is continued for 1.5 hours. The obtained material is dispersed through a colloid mill and then transferred to a reaction kettle. Reduce to 500rpm, and stir for 1 hour, then raise the temperature to 190°C, add 6 parts of styrene-butadiene-styrene thermoplastic elastomer (SBS), keep the temperature at 180-190°C, and stir at 500rpm for reaction After 2.5 hours, reduce the stirring speed to 300rpm, add 27 parts of talcum powder, keep the temperature at 180-190°C, and continue stirring for 1 hour to obtain the thermal insulation elastomer modified asphalt coating material.

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...
