Recently, the company's independently developed new material and product, the toughened and impact-resistant epoxy resin mortar, has been awarded a national invention patent. The invention name is: A toughened and impact-resistant epoxy resin mortar and its preparation method. Patent No. ZL 2020 1 0501272.5.
During the operation of hydraulic spillway structures, the concrete surface will show a certain degree of defects due to water flow scouring and erosion, especially when the water flow contains a certain amount of sediment, the damage is even greater. The concrete structure with defects that has been in operation for a long time through alternating flood seasons and dry seasons may shorten its life cycle, so it is necessary to carry out impact-resistant protection treatment on the surface of the hydraulic spillway concrete in a timely manner.

Epoxy resin is one of the most widely used impact-resistant materials in hydropower and water conservancy projects. Epoxy resin mortar is a new type of thin-layer repair material composed of epoxy resin, curing agent, and hard filler. It has high strength, good impact and abrasion resistance, and excellent bonding force. It can be used for repairing shallow defects such as pores and sand lines on the concrete surface, as well as for concrete waterproofing, carbonation protection, micro-crack sealing, and appearance beautification.
The toughened and impact-resistant epoxy resin mortar invented by the company this time uses epoxy-terminated polysiloxane as a modifier. By using the epoxy active end group and the bonding main resin to graft copolymerize, the siloxane chain is introduced, and stable and flexible Si-O bonds are introduced into the cured structure, greatly enhancing its fracture toughness. By using brominated nano-lightweight calcium to replace conventional fillers such as talc powder, microsilica powder, and mica powder, the UV resistance and anti-aging performance of the cured mortar are improved, and the powdering of the epoxy resin material is delayed.

When traditional materials cannot completely solve the problems of wear and cavitation of hydraulic spillway structures, epoxy resin mortar, as a new type of material with good impact resistance, wear resistance, comprehensive performance, and convenient construction, can provide important guarantees for the safety and durability of hydraulic spillway structures.
To date, the company has applied for more than 20 patent technologies, including 8 invention patents (1 of which has been authorized), and 14 utility model patents (13 of which have been authorized).
In the future, Hangzhou Meibu Materials Technology Co., Ltd. will continue to forge ahead and make greater efforts in technological innovation to achieve the transformation of more new technologies, new materials, and new processes, and to promote the development of hydropower and water conservancy engineering materials to a new level.
