Problems solved by technology

However, the epoxy resin grouting material mainly has the following problems: the viscosity of the epoxy resin is too high, and it is not easy to inject during the grouting process; when the epoxy resin is added with other filler additives such as sodium silicate, the filler has a strong adsorption force to the epoxy resin, and the filler distribution is not good. Uniformity, unable to achieve uniform filling and bonding, it is easy to cause low grouting strength, reduced adhesion, and easy cracks; during the grouting process, it is greatly affected by the environment, and it is easy to cause dry cracking after hardening. Oxygen resin produces water accumulation and water seepage after grouting, the plugging is not firm, and the compressive strength is low
However, the grout of this invention suffers from poor chemical resistance and shrinkage over time

Abstract

The invention relates to a high-penetration non-shrink epoxy grouting material. The high-penetration non-shrink epoxy grouting material is formed by a component A and a component B, The component A comprises the following raw materials in parts by mass: 60-80 parts of epoxy resin, 20-35 parts of an active diluent, 10-20 parts of alumina short fiber, and 3-5 parts of an oxidizing agent, the component B comprises the following raw materials in parts by mass: 10-20 parts of a curing agent, 8-12 parts of benzyl alcohol, 4-8 parts of a vinyl modifier, and 2-4 parts of a catalyst. Compared with theprior art, the high-penetration non-shrink epoxy grouting material has the following advantages that alumina fiber is used for enhancement, and the grouting material has good corrosion resisting performance and high intensity; the selected curing agent contains eight amino caged polysilsesquioxanes, and the grouting material after complete solidification has high crosslinking density and intensity; the vinyl modifier is used for modification, and the grouting material has high toughness.

Description

technical field [0001] The invention relates to a grouting material, in particular to a high-permeability non-shrinkage epoxy grouting material. technical background [0002] Since the promotion and application of grouting materials in China in the 1990s, they have been widely used in equipment installation, bolt anchorage, and reinforcement and renovation projects of many large and medium-sized enterprises. The scope of use has gradually expanded from a single metallurgical industry to Municipal, environmental protection, electric power, ports and other industries. Epoxy resin has the characteristics of high bonding strength, can be cured at room temperature, high mechanical properties and good corrosion resistance, so it is widely used in many fields such as electronics, machinery, construction, etc. as adhesives, coatings, and grouting materials. Epoxy resin grouting material is currently the most widely used chemical grouting material. This type of material has good im...
