Problems solved by technology

By adjusting the formula, the weather resistance, cohesiveness and weather resistance of the waterproof membrane are improved, but it needs to prepare different modified asphalt, and then modify it after mixing. The preparation method is relatively complicated, and the kinematic viscosity of the product is relatively high. Larger, more difficult to construct, and low temperature performance needs to be improved

[0028] All raw materials used in the examples are commercially available unless otherwise specified.

[0029] Examples and comparative examples

[0030] Prepare bitumen modifier by the raw material composition of table 1, wherein softening agent can be any one or more in polycyclic aromatic hydrocarbon rubber oil, naphthenic rubber oil, aromatic base rubber, above several softening agents to product The effect is the same, and mutual replacement has little effect on the performance of the product; the coupling agent can be any one or more of silane coupling agent KH580, silane coupling agent KH550, and silane coupling agent KH792. The effect on the product is the same, and mutual replacement has little effect on the performance of the product. For convenience of comparison, polycyclic aromatic hydrocarbon rubber oil was used as the softener in the examples and comparative examples, KH550 was used as the coupling agent, peptizer A89 was used as the peptizer among the rest of t...

Abstract

The invention relates to the technical field of asphalt modifiers, in particular to an asphalt modifier for a self-adhesive waterproof coiled material and a preparation method of the asphalt modifier. The asphalt modifier for the self-adhesive waterproof coiled material comprises the following raw materials in parts by weight: 50-70 parts of styrene butadiene rubber (SBR), 30-50 parts of SBS, 1-5 parts of stearic acid, 20-40 parts of calcium carbonate, 3-10 parts of a softening agent, 1-5 parts of polyethylene wax, 0.3-0.8 part of a peptizer, 1-5 parts of petroleum resin, 0.1-2 parts of a coupling agent, 0.1-2 parts of a dispersing aid and 0.3-1 part of a separant, wherein the total weight parts of the SBR and the SBS is 100. According to the asphalt modifier for the self-adhesive waterproof coiled material, the performance of the self-adhesive waterproof coiled material can be improved by adding a small amount of the asphalt modifier, and the low-temperature performance of the self-adhesive waterproof coiled material is improved; and the asphalt modifier is high in elasticity and softening point, small in kinematic viscosity and high in viscosity, and has good solubility, fast dissolving speed and small possibility of bonding and aging compared with a traditional product.

Description

technical field [0001] The invention relates to the technical field of asphalt modifiers, in particular to a self-adhesive waterproof membrane asphalt modifier and a preparation method thereof. Background technique [0002] Self-adhesive rubber asphalt waterproofing membrane is a self-adhesive waterproofing membrane with polymer resin and high-quality asphalt as the base material, polyethylene film and aluminum foil as the surface material, and a self-adhesive isolation layer. The product has extremely strong bonding performance and self-healing property, and is suitable for construction in high and low temperature environments. The product has good low temperature resistance, and is the best waterproof, moisture-proof and sealing material for subways, tunnels and non-fire sites, and is also suitable for waterproof and anti-corrosion projects of pipelines. [0003] In actual production, it is necessary to add various additives to asphalt to improve the mechanical properties...
