Description

TECHNICAL FIELD [0001] The present invention relates to an acrylic-based coating material having improved visibility and an application method therefor,

The present invention relates to an acrylic-based coating material for packaging having improved visibility, and more particularly to an environmentally friendly and environmentally friendly coating material which can minimize the problems of adhesiveness and durability of paints applied to a sidewalk or a road surface, Based paint and an application method of the acrylic-based paint for packaging, which has improved visibility that can maximize visibility and the like.

Generally, on the surface of concrete and asphalt pavement applied to walkways or roads, road surface information such as direction guidance symbols and speed limit signs, road information such as a pedestrian crossing, a school display, a bus lane mark, And bicycle road markings are displayed on the surfaces of elastic packaging materials applied to physical education and play facilities or walkways, and waterproofing materials applied to interior paint such as buildings or waterproof paint on the roof.

Such road surface markings shall be provided in accordance with Article 4 of the Road Traffic Act, Article 3 of the Enforcement Regulations of the same Act, road surface markings prescribed in the Traffic Road Surface Marking Installation and Maintenance Manual, (School - zone), the elderly protection zone (silver - zone), and the youth protection zone (red - zone).

Such road markings, letters, numbers, and other road markings provide information that enables safe driving or walking to vehicles using roads, bicycles, and pedestrians, and maintains the order of operations.

In particular, such road surface markings allow the driver to easily identify the lane on the pavement due to light reflections generated from the headlights of the vehicle during the nighttime operation of the vehicle when the road surface is wet due to snow or rain, And should be marked on the surface of the road so that interference with traffic flow is minimized.

As a conventional method for installing such road surface markers, a method of displaying a manipulator on the site by using a room temperature type paint or a fusing type road marking paint using general paint, or using an adhesive sheet is mainly used .

On the other hand, in the case of an adhesive sheet having a relatively short construction time and a variety of shapes and colors, the adhesive sheet can not process the pores of the road surface, thereby overcoming the peeling due to moisture penetration, dust, And there are various defects such as material loss after cutting.

In addition, the conventional construction methods have a problem that the fading and abrasion cycle is short, resulting in frequent traffic congestion due to repeated construction work while controlling the roads frequently.

Since volatile oil-based paints are used in most of the paints used in lane work on the road, volatile substances at the time of construction and materials that are worn out due to the passage of vehicles after the construction are a new problem causing environmental pollution .

On the other hand, there is also known an eco-friendly coating composition for minimizing human harmful components emitted from paints and conforming to environmental standards. However, in order to improve the visibility, the paint composition necessarily includes a fluorescent powder other than glass beads, There are too many essential components and there is a problem that it is difficult to commercialize the coating composition due to the complicated process of manufacturing the coating composition leading to the thickening step, dispersion step, mixing step, charging step, coloring step and viscosity step.

In the case of a paint containing glass beads or the like, the adhesion strength or durability of the coating film is low and the glass bead tends to be easily separated by the pedestrian and / or the vehicle.

Accordingly, the present invention has solved the above problems by securing visibility by attaching glass beads by using an environmentally friendly water-soluble acrylic paint excellent in adhesion to the surface of a sidewalk or a roadway.

According to one embodiment of the present invention, the acrylic-based paint for packaging according to the present invention comprises 20 to 25% by weight of octyl acrylate, 1 to 5% by weight of alpha-methyl acrylic acid, 20 to 25% by weight of methyl methacrylic acid, 60% by weight, a primer layer formed on the base layer; 40 to 50% by weight of octyl acrylate, 1 to 10% by weight of alpha-methylacrylic acid and 40 to 50% by weight of octyl acrylate based on 100 parts by weight of the powder consisting of 40 to 60% by weight of Portland cement, 30 to 50% by weight of silica, and 5 to 15% 5 to 15 parts by weight of an acrylic resin composed of 40 to 50% by weight of methyl methacrylic acid, and 3 to 10 parts by weight of water, a base powder layer formed on the primer layer; 40 to 50% by weight of octyl acrylate, 1 to 10% by weight of alpha-methylacrylic acid and 40 to 50% by weight of octyl acrylate based on 100 parts by weight of the powder consisting of 40 to 60% by weight of Portland cement, 30 to 50% by weight of silica, and 5 to 15% 5 to 15 parts by weight of an acrylic resin composed of 40 to 50% by weight of methyl methacrylic acid, 3 to 10 parts by weight of water and 5 to 15 parts by weight of glass beads, a top powder layer formed on the base powder layer; And a coating layer composed of 60 to 70% by weight of an acrylic resin, 10 to 20% by weight of 2-ethoxyethyl acetate, 10 to 20% by weight of xylene and 1 to 5% by weight of an additive, and a coating layer formed on the top powder layer.

In one embodiment, the base layer may be a bottom surface on a sidewalk or driveway, and may be comprised of a material such as concrete and / or asphalt. The primer layer formed on the base layer is composed of 20 to 25 wt% of octyl acrylate, 1 to 5 wt% of alpha-methylacrylic acid, 20 to 25 wt% of methyl methacrylic acid, and 50 to 60 wt% of water. The primer layer is applied to secure the adhesion between the base layer and the base powder layer to be applied later, and is combined with a powder component such as cement having excellent adhesion property and excellent compatibility with acrylic resin. The mixing ratio of the octyl acrylate, alpha-methyl acrylic acid, methyl methacrylic acid and water is selected in consideration of the above-described contents and workability.

In one embodiment, the base powder layer formed on the primer layer comprises 100 parts by weight of a powder comprising 40 to 60% by weight of Portland cement, 30 to 50% by weight of silica, and 5 to 15% by weight of titanium dioxide, 5 to 15 parts by weight of an acrylic resin composed of 40 to 50% by weight of octyl, 1 to 10% by weight of alpha-methyl acrylic acid and 40 to 50% by weight of methyl methacrylic acid, and 3 to 10 parts by weight of water.

The Portland cement is preferably added in an amount of 40 to 60% by weight based on the powder component, and if it is less than 40% by weight, the strength and stain resistance of the paint are deteriorated, and if exceeding 60% by weight The strength and stain resistance of the undercoat are excellent, but cracks are generated, which deteriorates the strength and deteriorates the physical properties.

In another embodiment, the silica sand added as a filler to the powder component is used to reinforce the strength of the paint. Preferably, the silica component is mixed in an amount of 30 to 50 wt% with respect to the powder component, and when it is less than 30 wt% And if it exceeds 50% by weight, the strength becomes weak.

If it is less than 5% by weight, There are disadvantages economically disadvantageous, but not particularly limited.

In one embodiment, 5 to 15 parts by weight of the same acrylic resin component used as the primer layer and 3 to 10 parts by weight of water are added to 100 parts by weight of the powder thus formed to form a base powder layer.

If the amount of the acrylic resin is less than 5 parts by weight, the adhesive strength to the primer layer and the top powder layer including the glass beads to be applied later is lowered. If the amount is more than 15 parts by weight, the adhesion is excellent but the durability of the paint itself becomes poor.

On the other hand, the water used as a solvent is added in an amount of 3 to 10 parts by weight based on 100 parts by weight of the powder in consideration of workability and the like.

Thus, a top powder layer containing glass beads is further formed on the base powder layer so as to improve adhesion between the cement component and the glass beads.

In one embodiment, if the amount of the glass beads used is less than 5 parts by weight, the visibility effect is lowered. If the amount is more than 15 parts by weight, adhesion with the base material is decreased. The glass bead preferably has a refractive index of 1.8 or more and a particle diameter of 100 占 퐉 or less, more preferably a glass bead having a functional group for improving adhesion such as a silane group bonded thereto. The specific gravity of the glass beads is preferably 4 or more for uniform dispersion of the glass beads.

According to another embodiment, the coating layer formed on the top powder layer comprises 60 to 70% by weight of acrylic resin, 10 to 20% by weight of 2-ethoxyethyl acetate, 10 to 20% by weight of xylene and 1 to 5% . The coating layer contains acrylic resin as a main component for the adhesive strength with the top powder layer, shortens the curing rate, and uses 2-ethoxyethyl acetate and xylene as a solvent for the purpose of increasing the strength.

According to one embodiment, the acrylic resin is selected from the group consisting of methyl (meth) acrylate, ethyl (meth) acrylate, isopropyl (meth) acrylate, butyl (meth) (Meth) acrylate, styrene, and (meth) acrylonitrile. These additives include, but are not limited to, antioxidants, antifoaming agents or mixtures thereof.
