Abstract

The invention discloses a sizing material with a curing agent for improving the stripping performance of an S-CLF coiled material. 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 pre-sol, 0.5-1.5% of SBR, 0.01-0.08% of a heat stabilizer, 0.01-0.08% of modified petroleum resin, 1-8% of the curing agent and the balance of filling powder. According to the sizing material , numerous raw materials are selected and compounded, and particularly, the curing agent is properly used, so that the stripping performance of the S-CLF coiled material and post-poured concrete is good, and the parameter requirements in the enterprise standard Q / 320584 PAI011-2019 are met. 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 the problem that the stripping strength of the SCLF sizing material coiled material and post-cast concrete has defects is solved. Meanwhile, other properties are ensured to meet the standard requirements.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and mainly relates to a rubber material with a curing agent improving 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 ...
