Description

Impregnation composition of porosity materials

The present invention relates to an impregnating composition of a porous material having an excellent sealing effect, and in particular, the first methacryl-based monomer and the second (meth) acrylic monomer in the impregnating composition are mixed in an appropriate composition ratio to increase the washing power, and occurs after the process It relates to an impregnating composition that can be reduced waste of the waste solution by reducing the compatibility of the washed impregnation liquid and water, and can significantly reduce the environmental pollution factor.

The impregnation composition is used to fill the voids of a material made of a cast product having a void, a sintered metal, an aluminum alloy, or the like to secure airtightness.

Conventional impregnating compositions are largely divided into inorganic and organic. Inorganic impregnating agents include silicate-based water glass, and organic-based anaerobic acrylic resins, thermosetting unsaturated polyester resins, and acrylic resins are used. The inorganic impregnation composition has a very long curing time due to curing by moisture evaporation, a high viscosity, and low penetration efficiency of the impregnation composition. In particular, it is accompanied by a volume reduction after curing, has a large discharge amount of liquid and contains a low boiling point material, it is not preferable to apply to relatively large pores. Anaerobic acrylic resins and thermosetting unsaturated polyester resins have a shorter curing time and a higher penetration efficiency of the impregnating composition than the inorganic impregnating agents, but both the curing time and the penetration efficiency of the impregnating composition are inferior to those of the thermosetting acrylic resin.

Therefore, the product of the impregnating composition market is currently commercializing a thermosetting acrylic resin, which is one of organic-based vinyl compounds having a short curing time, low viscosity, high penetration rate, and high work efficiency. However, in the case of thermosetting acrylic resin, it is possible to wash with water in the surface cleaning process after pore impregnation of the material, but due to its low cleaning power, impregnation components remain on the surface of the material, causing defects or processing costs for the waste liquid treatment generated after cleaning. It causes the problem of pollution. In addition, the stability of the impregnating composition with the addition of moisture is low, and the rate of change and volume shrinkage of the cured product due to heating loss is high.

An acrylic monomer comprising a krill monomer, a second acrylic monomer for imparting hardness to the cured product, and a third acrylic monomer for imparting a bonding force between the monomers; Antioxidants; Light stabilizers in liquid form of cyan acrylic esters; And a resin impregnating agent including a surfactant, but these are all those that emphasize effective improvement in environmental problems and economics by using water-insoluble acrylic monomers, so that the first methacryl monomer and the second monomer as in the present invention. By mixing the (meth) acrylic monomer and the third (meth) acrylic monomer in an appropriate ratio, the effect of improving the washing power and reducing the environmental pollutant in the waste liquid is simultaneously achieved, and the stability of the impregnating composition due to the addition of moisture and the curing according to the weight loss No impregnating composition has been found which can exhibit the effect of reducing the change in water.

In addition, the applicant has proposed an environmentally friendly resin impregnating agent using a vinyl-based acrylic monomer in Patent Application No. 10-2011-0118761, which also does not use the acrylic monomer used in the present invention, It is focused on the effect of reducing the generation of COD and is also somewhat different from the impregnating composition of the present invention.
