Abstract

The invention discloses a novel high polymer peristaltic grouting material. The modified asphalt is prepared by mixing the following components in percentage by mass: 18%-25% of asphalt, 18%-25% of naphthenic oil, 9%-13% of styrene, 8%-12% of butadiene styrene rubber, 5%-8% of a cross-linking agent, 3%-6% of a high-temperature antioxidant, 8%-12% of machine sand and 9%-14% of soft calcium. The invention also discloses the novel high polymer peristaltic grouting material. The problem of combination of the waterproof material and a building base layer can be well solved, and the waterproof material is a novel waterproof material with excellent elastic-plastic performance, self-healing performance, bonding performance and aging resistance; when in use, the waterproof material can meet the construction requirements of different projects in different climatic environments, and has incomparable comprehensive application performances such as fatigue resistance, creep resistance, water channeling resistance and the like compared with other waterproof materials.

Description

technical field [0001] The invention relates to a novel high polymer creeping grouting material and a manufacturing process thereof. Background technique [0002] Grouting material: selected to achieve a certain engineering purpose, it can exist in liquid form, and it is convenient to use hydraulic pressure, air pressure or electrochemical principles to inject into the internal space of the corresponding medium, such as cracks, cracks, pores, etc., and has the ability to cement and solidify. The general term for a class of engineering materials whose leakage channels are blocked and whose physical properties and mechanical properties are improved. [0003] The existing grouting materials on the market have some defects in elastic-plastic properties, self-healing properties, bonding properties and aging resistance, and cannot meet the requirements of the current waterproofing field for grouting materials. Contents of the invention [0004] The purpose of the present invent...
