Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an environmentally friendly packaging composition using Masato,

The present invention relates to an eco-friendly packaging material composition using Masato and a packaging method using the same. More specifically, the present invention relates to an eco-friendly packaging material composition using Masato, Ascon packaging, rubber? The present invention relates to an eco-friendly packaging material composition and a packaging method using the same, which are capable of constructing environmentally friendly road pavement when repairing road pavement and road pavement without cement.

In addition, the present invention is capable of paving roads without cement, and is excellent in adhesiveness, strength and crosslinkability with soil particles by being directly applied to soil or mixed with soil, and is environmentally friendly after cement or asphalt pavement Environment-friendly packaging material composition using Masato which can solve the phenomenon that the surface of the road is separated by repeated process of icing and thawing under the condition of sub-zero and image temperature without causing secondary environmental pollution .

Currently, asphalt pavement or concrete pavement are mostly used in pavements such as roads, India, and plazas, and these pavements are generally not permeable. Therefore, in case of insufficient drainage, large amount of water can not be drained during rainfall, and it becomes high on the top of the packaging material. Such high water not only hinders road traffic, but also increases the risk of accidents by reducing the slip resistance when braking the vehicle when a large amount of water exists on the road surface.

In addition, asphalt and concrete roadway packaging materials are not permeable and environmentally friendly, and when exposed to sunlight, radiant heat is generated to raise the atmospheric temperature, concentrate the stormwater during storm, and flood the river. Especially in the summer season.

In order to solve these problems, various types of permeable packaging materials have been proposed, and permeable concrete has been developed and used for packaging of life-related roads, plazas, parking lots, and the like. Conventionally, a packing material made of a water-permeable concrete has a void formed in the inside of the packing material by simply not using fine aggregate when the concrete is mixed. The coarse aggregate in the concrete packing material is merely combined with the cement paste to deteriorate the mechanical properties and durability , Because it is designed by the bending strength rather than the compressive strength and has a large cross-sectional area of the packaging material, cracks tend to occur due to temperature stress and drying shrinkage, and it is easy to receive freezing and thawing action.

In order to solve this problem, soil pavement method using cement, hardener, iron oxide, lime, etc. has been carried out in recent years in consideration of natural environment, but it is widely used by mixing cement in soil, Soil hardening agent is used to increase the strength and to accelerate the hardening speed. In case of pavement using soil hardener, there is a problem that the ground is collapsed. The surface of the soil is cracked due to the repeated process of freezing and thawing under the condition of passing through the surface of the pavement, The waste of the industrial waste is generated.

On the other hand, the use of soil hardening agent is limited due to the restriction of sand adhesion, warm climate, and rainfall and humidity. In the four seasons, The particles of the emulsion resin are destroyed, so that the function of the fixing agent is degraded, and the problem of inconvenience of maintaining and storing the image temperature during storage and economical loss are exposed.

Therefore, in recent years, attempts have been made to use water-soluble emulsions such as methyl methacrylate, polyvinyl alcohol, and ethylene-vinyl acetate copolymer as a soil hardener.

However, when such a polyvinyl alcohol is used, the surface strength, flexibility, and water resistance are poor due to the limit of the vinyl material, so that sufficient water resistance can not be imparted to the surface of the soil, and polyvinyl alcohol swells when the water content is large.

In addition, the ethylene-vinyl acetate copolymer is emulsified using a protective colloid. Since the viscosity and fluidity of the ethylene-vinyl acetate copolymer are greatly changed, application processing and workability can be controlled. However, when the curing film is formed on the surface of the soil, , Surface strength and flexibility, and water resistance are poor, resulting in peeling of the surface and disruption of the soil.

For this purpose, road pavement using acrylic emulsion or vinyl emulsion contains a large amount of surfactant, and there are restrictions on freezing in winter and use of preservative to prevent the deterioration of the composition, so that toxic substances and environmental hormones are released to pollute soil and water quality Causing side effects.

Also, in the case of cement based on an acrylic emulsion or a vinyl emulsion, a curing agent containing a solidifying agent must be added with a coloring agent containing iron oxide, which contains a heavy metal, in order to obtain an ocher color, so that harmful components are harmful to human beings.

In general, Masato pavement is used in a square or school playground by using Masato to install Masatoto without mixing hardener and to make a number of rollers around it. The Applicant uses Masato which is a weathering residue of granitic rock and uses environmentally friendly packaging material .

It is colorless transparent and sweet and sticky liquid, and has strong hygroscopicity. It is used as an anti-drying agent for food toilet paper, a tinning agent, a paint printing ink, a raw material for producing transparent soap, an analysis reagent, and a lubricant.

In addition, the present invention uses a silicone antifoaming agent as a defoaming agent. The antifoaming agent is used for preventing cohesion of the coating film such as bubbling in the coating film. If bubbles remain in the coating film, adhesion failure or physical physical properties of the coating film may be deteriorated. A silicon-based defoaming agent can be used in terms of maximizing the force.

The strength improving agent is composed of potassium chloride and sodium chloride. The potassium chloride is mixed with other compounds to close the pores and increase the strength.
