Abstract

The invention discloses a sizing material for improving the stripping performance of an S-CLF coiled material by using an acid-base regulator. The sizing material is prepared from the following raw materials in percentage by weight: 40-60% of asphalt, 4-9% of modified oil, 4-9% of SBS, 2-8% of presol, 0.5-1.5% of SBR, 0.03-0.08% of a heat stabilizer, 0.03-0.08% of modified petroleum resin, 4-10% of the acid-base regulator, and the balance of filling powder. It is proved that the SBS, the pre-sol, the SBR, the modified oil and the asphalt are matched for use, so that the rubber, the asphalt and the modified oil are better combined, the adhesion effect of the rubber waterproof coating relative to a base layer is improved, and the waterproof effect is enhanced. According to the invention, the formula of the sizing material is optimized, the viscosity of the sizing material is reduced and the performance of the sizing material is improved through component selection and content proportioning, excellent stripping performance is achieved through combination and compounding of the components, and therefore, the problem that the stripping strength of the S-CLF sizing material coiled material and post-cast concrete has defects is solved; and meanwhile, other properties also satisfy the standard requirements.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and mainly relates to an acid-base regulator to improve the stripping performance of S-CLF coils. Background technique [0002] Waterproof roll material is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering foundation and building There is no leakage connection between objects, which is the first barrier for waterproofing of the whole project and plays a vital role in the whole project. The self-adhesive waterproof membrane of S-CLF strong cross-laminated membrane developed on the market can combine the advantages of polymer membrane and self-adhesive modified bitumen waterproof membrane, and avoid their respective shortcomings. It has excellent physical properties and tensile properties. It is 2 to 3 times that of tradit...
