Waterproofing method using water-soluble acrylic waterproofing agent }

The present invention relates to a waterproofing method using a water-soluble acrylic waterproofing agent, and more particularly, by including a water-soluble acrylic resin and a water-soluble acrylic silicone resin in the waterproofing agent used for waterproofing, the drying time of the waterproofing agent is faster than that of the urethane waterproofing agent, and the construction period Water-soluble acrylic with improved workability and durability by preventing cracks during the drying process and improving versatility as it can be applied to all undercoat, middle coat and top coat during waterproof construction It relates to a waterproofing method using a waterproofing agent.

In general, a coating film that protects the inner and outer walls of a concrete structure has good compressive strength, and has properties that withstand elasticity, acid resistance, alkali resistance, chemical resistance, and ozone resistance well.

However, as time elapses in the use of uncoated concrete structures, impurities such as organics, acids, alkalis, and inorganic salts cause a decrease in strength, water leakage, and corrosion of even buried reinforcing bars, resulting in further deterioration of the durability of the structure. do.

In addition, concrete structures basically have a certain degree of watertightness, but cracks occur inside and outside the structure due to microcracks that occur irregularly during curing, poor finishing of joints, and cracks due to external force transmitted from the outside. Leaks occur, which in turn further exacerbate cracks, impairing the function of concrete structures in the future.

In general, the most widely used resin for forming a coating film for imparting acid resistance and water resistance to a concrete structure is an epoxy resin or an unsaturated polyester-based resin. In particular, unsaturated polyester-based resins are used together with glass fibers, so-called FRP (Fiberglass Reinforced Plastics) resins, and are used in water tanks requiring acid resistance.

These epoxy resins and FRP resins have excellent acid resistance and are used in a waterproofing method of forming a coating film on the concrete surface to protect and waterproof the inner and outer walls of concrete structures. method is being used.

However, the epoxy-coated anticorrosive film has a strong film strength but has a low elastic elongation, making it inconvenient to use in a concrete structure structure where cracks occur due to continuous and repeated contraction and expansion of concrete. There is a problem of falling, and there is a problem that the drying time takes a long time and the air is increased.

The above-described invention refers to the background of the technical field to which the present invention pertains, and does not mean the prior art.
