Abstract

The invention relates to a polyurethane modified epoxy resin grouting material. The grouting material is characterized in that: the grouting material comprises an adhesive and a solid material according to a weight ratio of 1:4-8, wherein the solid material comprises coarse quartz sand, high aluminum cement, middle quartz sand, a pigment and fine quartz sand; and the adhesive comprises a polyurethane modified epoxy resin, a curing agent, an epoxy-based reactive diluent, a leveling agent, a defoamer and a dispersant. Compared with grouting materials prepared with the prior art, the polyurethane modified epoxy resin grouting material provided by the invention allows the toughness and the strength of the grouting material to be improved, the impact and the shock of mobile equipment to the base to be effectively reduced, the service life of the equipment and the base to be prolonged, better water resistance and oil resistance to be possessed and the cost to be reduced by about 50%.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a polyurethane modified epoxy resin grouting material. Background technique [0002] With the development of technology, the precision of some moving equipment is getting higher and higher, and the requirements for the foundation are also getting higher and higher, especially the stricter requirements for the seismic performance of the foundation are put forward. For example, the use of epoxy grouting material between the moving equipment and the foundation can effectively reduce the damage to the foundation caused by equipment vibration. At the same time, since the epoxy resin grouting material is a chemical grouting material, it also has certain resistance to acid and alkali. Played a very good role in protecting the equipment. [0003] However, due to the high brittleness of epoxy resin and its brittleness under strong vibration, the existing epoxy resin grouting m...
