Hyundai has been continuously researching and announcing the damage caused by the high industrialization of cement buildings and the expansion of polymer plastic materials. Among them, radon gas generated from cement and environmental hormones contained in plastics, and environmental conditions beneficial to the human body are gradually disappearing due to the destruction of the environment. It can be said that it is an environmental change that can bring a beneficial effect to the human body by replacing harmful substances such as unpleasant odor emitted from new construction, toxicity of cement, volatile organic compounds generated from building materials, and environmental hormones.

As national income increases, the public is getting more and more interested in health, and as a result, various types of health aid are being developed one after another. Among them, the recent attention is also far infrared and anion effects.

The present invention relates to far-infrared and anion-spun polyurethane polyurea functional resin compositions.

Polyurethane polyurea functional resin composition that emits far infrared rays and anions does not detect environmental hormones, volatile organic compounds, odors or harmful substances to human body compared to conventional epoxy resins or urethane resins. Conventional epoxy-based resins or urethane-based resins have a problem in that environmental hormones and volatile organic compounds are detected and odors are strong due to the toxicity of chemicals and are harmful to the human body.

In particular, when painting with an epoxy resin, it is not preferable from an environmental point of view.

Polyurethane polyurea functional resin composition that emits far infrared rays and anions is environmentally free of VOCs and no environmental hormones are detected. Polyurea is well known as an environmentally friendly material.

However, technology development regarding the function of radiating far infrared rays and anions to the polyurethane polyurea resin composition is not actively performed.

Therefore, the present invention has been made in anticipation of a beneficial effect on the human body by imparting the advantages of the polyurethane polyurea resin composition and the ability to radiate far infrared rays and anions, which can solve the problems of conventional epoxy resins and urethane resins. .

The present invention is to solve the disadvantages of the environmental hormone generated when the coating using the epoxy resin composition as in the prior art and the disadvantages of the volatile organic compounds generated when coating using the urethane-based resin composition as in the prior art The purpose of the present invention is to provide a resin coated with a two-component polyurethane polyurea and a polyurethane polyurea functional resin composition that emits far infrared rays and anions, which are suitable as environmentally friendly materials for civil engineering, construction, and industrial coatings.

The present invention is to achieve the above object of the present invention, Aromatic Modified Methylene Diphenyl diisocyanate (AMdMDD) 2 ~ 73wt%, Aromatic monomeric methylene diphenyl diisocyanate (Aromatics Monomeric Polyisocyanate prepolymer polymerized from 2 to 73 wt% of Methylene Diphenyl Diisocynate (AMcMDD) and 25 to 65 wt% of polyether polyol; 4-20 wt% of polyetheramine with molecular weight of 5000, 10-63 wt% of polyetheramine with molecular weight of 2000, 22-27 wt% of chain extender with molecular weight of 178.3, 4-6 wt% of pigment Polyurethane polyurea resin that emits far infrared rays and anions consisting of a polyamine mixture containing 0.5 to 1.5 wt% of absorbent, 1 to 20 wt% of far infrared ray and anion radioactive substance, and 1 to 2 wt% of dispersing additive compound. To provide a composition.

This is because the content of AMdMDD and AMcMDD is different in content depending on soft or hard. And polyol is in the above range because the isocyanate remainder.

In the above, it is preferable that AMdMDD has a molecular weight of 285, AMcMDD has a molecular weight of 250.3, and polyether polyol has a molecular weight of 2000. The molecular weight in the above is because the raw material of polyurea urethane is limited.

In addition, the polymerization in the above can be carried out in a conventional manner, the isocyanate content (NCO) of the polymerized polyisocyanate prepolymer is preferably 11 to 24% by content, which is a general waterproofing agent shore hardness of A 90 ~ 95 Is to satisfy this.

In addition, the far infrared ray and anion radiation material may use a rare earth-based anion powder or a bioceramic powder having a particle size of 5 ~ 10㎛, which can be used conventionally processed. The particle size of far-infrared ray and anion radioactive material in the above is to disperse with other raw materials, the above range is the standard particle size of general processing.

In addition, when the resin composition is coated on the coating, it is preferable to set it to 20 to 8000 µm. The coating thickness here is a general paint concept because it depends on the application.

In the present invention, since the reaction may be delayed in the case of the hybrid ultrafast urethane, the reaction may be accelerated by using a tin catalyst of 1 to 2 wt%, and mole to prevent overreaction due to moisture in the polyol raw material itself. It is also possible to use 1 to 2 wt% of an absorbent such as Morecular Sieve.

According to the present invention, by providing a polyurethane polyurea functional resin composition that emits far infrared rays and anions, concrete structures, steel structures, parking lots, steel pipes, water pipes, rehabilitation pipes, water tanks, bicycle roads, areas requiring abrasion resistance, wood, It can be used to coat various structures such as offshore structures, gas stations, oil refineries, gas pipes, oil pipelines, etc., which radiates far infrared rays and negative ions to activate cellular tissues of the human body. It also relieves tension and increases the respiratory immune system's ability to relax the mind and body.

It is the longest infrared ray among infrared rays. It has a longer wavelength than red light of visible light, so it is a kind of heat action. It absorbs well into material and has strong resonance effect on organic chemical molecules. When the wavelength reaches a long object, it is absorbed well and penetrates strong and penetrates up to 40mm of the human body and expands the capillaries by the body's warming action, which helps in blood circulation and cell tissue formation.

In addition, it has antibacterial and deodorizing effects and also has the effect of removing mold.

This action helps to eliminate the bacteria that cause various diseases.

It can be applied to various effects in civil engineering, architecture, and industrial fields with beneficial effects on human body.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments.

The description of the present invention through the embodiments is intended to be easily described by those skilled in the art, but the present invention is not limited thereto.

Polyurea is mixed with Methylene Diphenyl Diisocyanate at high temperature and high pressure 1: 1 volume ratio collision to form a coating resin. In addition, the reaction rate can be controlled by adding HDI, IPDI, H12MDI of Methylene Diphenyl Diisocyanate and prepolymer.

Polyurea is divided into 1: 1 volume ratio high temperature high pressure impact mixing spraying method and brush coating, and hardness can be adjusted.

Soft and hard furnaces are formed from Shoer A 45 ~ 99, and hard ones are formed from Shore D 55 ~ 80. Hardness adjustment is determined by the NCO% content, the chain extender content and the equivalence ratio. The lower the NCO% content, the closer it is to softness. Hardness is divided into soft and hard as the NCO% content is low and high.

Polyurea is a one-to-one volume ratio of high temperature and high pressure impingement mixed spray spraying system, which is currently used exclusively for polyurethane polyurea, and is divided into spray equipment manufactured in Korea and equipment manufactured in foreign countries.

Polyurea's equipment is divided into appropriate pressure and temperature settings, and the adjustments vary depending on temperature, climate, and site conditions. Winter and summer are set differently.

Brush Coating Polyurea is a method of painting with a brush, hera or roller.

With non-yellowing, HDI, IPDI, H12MDI are used to slow down and serve as polyurea repairs or polyurea topcoats.
