In general, concrete structures have been recognized as being semi-permanently available because of their high durability. However, recent researches and investigation of existing structures have revealed that aged deterioration phenomenon can not be avoided. There are cases in which the original function is lost without exceeding a long period of time.

Specifically, the surface damage caused by frequent deterioration of the existing L-shaped cross section, boundary stone, bridge slab section, pier, expansion joint, various concrete, and asphalt pavement is often caused, but there are not many repair methods, After the crushing, concrete re-installation or temporary cement mortar is applied to the surface.

In addition, the conventional compositions for surface repair and waterproofing have some adherence to asphalt but have poor adhesion to concrete surface. In case of the room temperature composition, due to excessive mixing of water, the material can not be frozen at the freezing temperature in the winter season, and in the case of the heating composition, the penetration ability is weak due to the characteristics of the rigid material after curing. Furthermore, both methods have difficulty in construction since they start to harden when the mixing time exceeds 10 seconds ~ 30 seconds after mixing. Because of these reasons, the conventional repairing composition did not sufficiently function as a surface repair material, and frequent flaws and poor construction caused a budget waste and an accident risk.

When the amount of oleic acid is less than 5 parts by weight, the control of hardening is insufficient. When the amount of oleic acid is more than 20 parts by weight, workability is poor due to excessive curing.

The vegetable oil is extracted from the pulp and seeds of plants and functions to prevent the penetration of water. If the amount of the vegetable oil is outside the range of 0.1 to 10 parts by weight, the effect of penetration of water is weak or it is not harmonized with other materials. .

Vegetable oil is rapeseed oil, sunflower oil, etc. It is an unsaturated fatty acid which is not sensitive to changes in external temperature and is eco-friendly. It enhances the function of surface repair material which must maintain its initial viscosity.

The anti-peeling agent (liquid phase) is used to prevent the composition from being peeled off from the structure. Less than 5 parts by weight of the anti-peeling agent is weak and the effect of peeling off is more than 30 parts by weight. Can be used.

The anti-peeling agent is a polyphosphoric acid-based liquid phase anti-peeling agent that stabilizes asphalt and latex to prevent peeling from existing attached surfaces.

The antioxidant is to prevent oxidation due to the action of oxygen generated in the materials, and amines, phenols and the like can be used, and 3 to 10 parts by weight is an optimum mixing ratio for preventing oxidation.

Glass fiber powders are characterized by being resistant to high temperature, having nonflammable properties, excellent in corrosion resistance and tensile strength, for example, having a size of 5 to 20 μm (capable of penetrating microcracks and capillary voids), less than 2 parts by weight Can not be used, and when more than 15 parts by weight, the effect of materials such as latex is deteriorated.

The method for producing the self-pliable latex type composite coating composition according to the present invention is as follows.

1. Mix the elastomer latex and emulsifier at a temperature of 50 to 150 ° C (1 to 2 hours). The temperature is a temperature at which the latex is maintained in a liquid phase.

2. Mix the No. 1 blend in a pre-boiled asphalt solution (AP-5) at a temperature of 100 to 210 ° C (within 1 hour). The temperature is the temperature for homogeneous mixing with the materials while maintaining the liquid phase without causing the asphalt liquid to set.

3. Add the curing-controlling oleic acid to the mixture of No. 2 and stir. The stirring conditions are within 30 minutes (5 to 30 minutes) at 100 to 210 degrees.

4. Add the vegetable oil to the mixture of 3 times and stir.

5. Add anti-peeling agent to Mixture No. 4 and stir.

6. Add antioxidant to 5 mixture and stir.

The steps 3 to 6 may be performed in a single process.

At this time, the latex and the emulsifier as the elastomer may be 1: 5 to 1:15 of the total weight, and the composition ratio of the latex and the emulsifier may be 1: 4 to 1:99 of the total weight of the asphalt .
