Description

Epoxy adhesive composition containing functional deodorant {EPOXY-BASED ADHESIVE COMPOSITION COMPRISING FUNCTIONAL DEODORANT}

The present invention relates to an epoxy-based adhesive composition used for the construction of building interior materials such as flooring flooring, and more particularly, by adding a functional deodorant to the epoxy-based adhesive composition, various raw materials contained in the composition with excellent mechanical and chemical properties Epoxy-based adhesive composition that can reduce the emission of odor and total volatile organic compounds (TVOCs) harmful to the human body occurs in.

Epoxy-based adhesives are widely used in various industrial fields according to characteristics such as strong adhesion, weather resistance, heat resistance, chemical resistance, and the like. In particular, residential and commercial facilities are constructed of high-grade flooring materials such as reinforced floors, ondol floors, steel floors, and wooden floors.In general, epoxy is required to provide strong adhesion to mortar (cement) surfaces and to deform materials. Based adhesives are generally used.

However, the adhesive increases the concentration of volatile organic compounds in the room due to the use of an organic solvent as a diluent, causing problems such as a new house syndrome, which is being particularly issued these days.

The sick house syndrome is an organic solvent used to dissolve the adhesive or paint pigment components in the building process, ie, benzene, toluene, asbestos, volatile organic compounds, including formaldehyde evaporate at a slow rate over time Therefore, the volatile organic compounds remain in indoor air for a long time and cause air pollution.

Therefore, various efforts are being made to reduce the concentration of volatile organic compounds remaining in the indoor air, such as frequent ventilation or a method of using a ventilation system that maximizes air circulation. However, the original solution is environmentally friendly, which does not emit harmful substances. To develop a product.

In addition, due to the serious indoor air pollution caused by volatile organic compounds generated from adhesives such as building materials used in houses, the Ministry of Environment discharged environmentally harmful substances under the "Indoor Air Quality Management Act" implemented in May 2004. Strictly regulating the use of materials has made it difficult to use conventional organic (epoxy) adhesives.

In order to solve the above problems, the present invention is to reduce the emission of odors such as amines generated in the existing epoxy-based adhesives and to significantly reduce the amount of volatile organic compounds (VOCs) harmful to the human body building materials such as environmentally friendly flooring materials It is an object of the present invention to provide an adhesive that can be usefully used for the construction of the product.
