Preparation of Low

In this work, a low-shrinkage, high-strength epoxy resin plugging agent was prepared based on a low-viscosity petroleum-based epoxy resin, and the curing agent and accelerator dosage were optimized, and the performance of injectable, mechanical, adhesion, and plugging was evaluated.

In modern construction engineering, waterproofing and leak sealing are critical technologies. This is especially true when dealing with issues such as cracks, holes, or settlement, where timely and effective leak repair ensures the structural safety and service life of buildings. This article explores the application of epoxy resin curing agents in leak sealing, along with their importance and operational steps.

I. Overview of Epoxy Resin Curing Agents

Epoxy resin is a high-performance thermosetting resin known for its excellent adhesion and chemical stability. During the curing process, it reacts with various materials to form a robust polymer network structure. These properties make epoxy resin curing agents ideal for leak sealing, particularly in scenarios requiring sealing and reinforcement.

II. The Importance of Leak Sealing

1. Prevent Water Damage: Water is one of the primary threats to buildings. Whether from groundwater or rain, it can cause significant damage. Effective leak sealing prevents moisture penetration, protecting the structure and internal facilities.
2. Extend Building Lifespan: Leakage accelerates the aging process of building materials, reducing their lifespan. Timely leak repair avoids this issue, thereby extending the building’s longevity.
3. Reduce Maintenance Costs: Leaks lead to frequent repairs and replacements, increasing maintenance expenses. Effective sealing minimizes future maintenance needs and lowers costs.

III. Operational Steps for Epoxy Resin Curing Agent Leak Sealing

1. Preparation: Before sealing, conduct a detailed inspection of the site to identify the leak’s location and cause. Gather tools and materials, including epoxy resin curing agents, gloves, and safety goggles.
2. Surface Cleaning: Thoroughly clean and grind the leak area to ensure full contact between the epoxy and the surface. Use sandpaper or an angle grinder until a metal sheen appears.
3. Apply Primer: To enhance adhesion, apply a primer around the leak. The primer, typically diluted epoxy resin mixed with a curing agent, should be evenly coated in a thin layer.
4. Fill Gaps: After the primer dries, fill the leak gaps with epoxy filler. Ensure no air bubbles remain to avoid compromising curing. Remove excess filler with a putty knife.
5. Apply Pressure: Press the epoxy against the substrate using a rubber roller or pressure equipment to ensure tight bonding.
6. Curing and Curing: Epoxy curing requires several hours to a day. Maintain suitable temperature and humidity, avoiding direct sunlight or high heat. After curing, inspect and repair if needed.

IV. Advantages of Epoxy Resin Curing Agent Leak Sealing

1. Fast Curing: Epoxy curing agents solidify quickly, shortening project timelines.
2. High Strength: Cured epoxy exhibits high strength and flexibility, withstanding external loads and deformations to ensure stability.
3. Corrosion Resistance: Epoxy resists acids, alkalis, and other chemicals, prolonging building lifespan.
4. Environmental and Safety Compliance: Epoxy curing agents produce no harmful gases during application and are harmless to humans, meeting environmental standards.

As an efficient waterproofing technique, epoxy resin curing agent leak sealing plays a vital role in modern construction. With proper procedures and scientific methods, it effectively resolves leakage issues, ensuring building safety and longevity. With technological advancements and new materials, this technique will continue to evolve, offering greater convenience and reliability to the construction industry.
