Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-slip packaging material composition and a non-slip packaging material,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a slip resistant packaging material composition used for improving sliding resistance of a road surface, and a method of forming a slip resistant packaging material using the same.

Generally, the non-slip wrapping material is applied to places where the sliding resistance is low (such as a road surface), a flat linear shape (plane linear shape) or a poor longitudinal line shape, a downhill road, a curve road, This is a traffic safety factor that ensures the safety of pedestrians and drivers by preventing pedestrians' pedestrian accidents and shortening the braking distance of vehicles, and by preventing a traffic accident by inducing the vehicle to slow down.

The conventional non-slip wrapping material is mainly composed of a thermoplastic resin such as rosin ester resin or hydrocarbon resin, an epoxy resin, a unsaturated polyester resin, methyl methacrylate , MMA, methyl methacrylate) resin, and the like.

Such a conventional anti-slip wrapping material may cause slip resistance due to cracks in the wrapping material, aggregate contained in the wrapping material falling off the wrapping material, poor adhesion of the wrapping material to the wrapping object such as the road surface, and the like. , Durability and the like are poor.

Specifically, the slip resistant packaging material using a thermoplastic resin has a problem that the resistance to sliding is drastically reduced due to the relatively low weather resistance, so that the aggregate is easily removed. Further, there is a problem that the adhesion failure with the packaging object is easily caused and the durability is lowered.

The anti-slip packaging material using an epoxy resin is excellent in adherence to a packaging object, but has a curing time of 3 to 4 hours, which is disadvantageous in terms of construction. Of course, there is also a problem of causing traffic congestion due to long curing time. In addition, there is a problem that cracks are generated due to insufficient impact resistance and elongation, and the packaging material is dropped.

The non-slip packaging materials using the unsaturated polyester resin have a good curing time of about 1 hour. However, like the non-slip packaging materials using the epoxy resin, the impact resistance is poor and the flexibility is poor, There is a problem that arises.

The non-slip wrapping material using the methyl methacrylate resin can solve the problem of the above-mentioned non-slip wrapping material using the thermoplastic resin, epoxy resin or unsaturated polyester resin, but it is one of the characteristics of the methyl methacrylate resin There is a problem that the crack easily occurs due to brittleness. A non-slip wrapping material using a methyl methacrylate resin is a reaction type product in which a mixture of a base and a curing agent is used. The curing property varies depending on the ambient temperature at the time of construction. In a relatively high temperature environment such as a summer, However, in a low-temperature environment of about 5 ° C or less, such as in the winter season, there is a problem that the curing rate is significantly slowed to about 2 to 3 hours.

Hereinafter, a method of forming a non-slip packaging material according to the present invention and a method of forming a non-slip packaging material using the same will be described.

(1) Non-slip packaging composition

The anti-slip package composition according to the present invention includes a curing agent for curing a subject and a subject containing the resin.

The resin, one of the main constituents of the subject, is an ultra rapid hardening resin. The fast cure resin included in the subject is a mixture of triethyleneglycol dimethacrylate (TEGDMA), butyldiglycol methacrylate and N, N-dimethyl-p-toluidine -toluidine).

Triethylene glycol dimethacrylate (TEGDMA) is a monomer having a high crosslinking density which imparts fast hardening upon reaction with a curing agent and improves the hardness, abrasion resistance and impact resistance of the non-slipping packaging material. It plays a role.

Butyldiglycol methacrylate, together with triethylene glycol dimethacrylate, imparts a rapid hardness and is a monomer having excellent flexibility, which improves the impact resistance of the non-slip packaging material and prevents the occurrence of cracks.

N, N-dimethyl-p-toluidine provides a quick hardening by initiating curing and accelerating curing in reaction with a curing agent, and improves the flexibility of the nonslip packing material to prevent cracks from being generated in the nonslip wrapping material It plays a role.

5 to 10 parts by weight of triethylene glycol dimethacrylate, 5 to 10 parts by weight of butyldiglycol methacrylate, and N, N-dimethyl-p-toluidine are contained in 100 parts by weight of the quick- Preferably 1 to 3 parts by weight.

When the quick-setting curing resin contains less than 5 parts by weight of triethylene glycol dimethacrylate, the fastness imparted to the non-slip packaging material may be reduced. If the quick-setting curing resin contains more than 10 parts by weight of triethylene glycol dimethacrylate, the hardness of the non-slip packaging material may increase and cracks may easily occur.

If butyl hypoglycol methacrylate is contained in less than 5 parts by weight in the quick cure resin, the fastness and flexibility (elongation) imparted to the anti-slip package may be lowered. If the quick-setting curable resin contains more than 10 parts by weight of butyldiglycol methacrylate, the hardness of the anti-slip packaging material may be reduced, which may cause the aggregate (hard aggregate) described later to easily fall off from the anti-slip packaging material.

If the quick-setting curing resin contains less than 1 part by weight of N, N-dimethyl-p-toluidine, the curing time of the anti-slip package may be significantly retarded. If the quick-setting curing resin contains more than 3 parts by weight of N, N-dimethyl-p-toluidine, discoloration of the anti-slip packaging material may occur during the curing process and the hardness of the anti-slip packaging material may be reduced.

The fast cure resin may be selected from the group consisting of methyl methacrylate (MMA), butyl acrylate (BA), 2-ethylhexyl acrylate (2-EHA) and N, N (N, N-bis- (2-hydroxypropyl) -p-toluidine) may be further added.

Methyl methacrylate (MMA) improves the strength and abrasion resistance of the non-slip packaging material and improves the adhesion of the non-slip packaging material to the package.

Butyl acrylate (BA) and 2-ethylhexyl acrylate (2-EHA) lower the glass transition temperature (Tg) of the quick cure resin to impart flexibility to the non-slip packaging material.

N, N-bis- (2-hydroxypropyl) -p-toluidine performs a hardening initiation and curing accelerating function in reaction with a main-chain curing agent.

30 to 40 parts by weight of methyl methacrylate, 30 to 40 parts by weight of butyl acrylate, 5 to 15 parts by weight of 2-ethylhexyl acrylate are contained in 100 parts by weight of the quick cure resin, N , And N-bis- (2-hydroxypropyl) -p-toluidine may be contained in an amount of 1 to 5 parts by weight.

If the quick-setting curable resin contains less than 30 parts by weight of methyl methacrylate, the aggregate (hard aggregate) to be described later may fall off from the non-slip packaging material due to insufficient hardness and weatherability of the non-slip packaging material, It may cause discoloration. If the quick-setting curing resin contains methyl methacrylate in an amount exceeding 40 parts by weight, the impact resistance is greatly reduced due to an increase in the hardness of the non-slip packaging material, so that cracks are generated in the non-slip packaging material, .

If the quick-setting curing resin contains less than 30 parts by weight of butyl acrylate, the flexibility of the non-slip packaging material may be greatly reduced, and the low-temperature impact resistance of the non-slip packaging material may be greatly reduced and cracks may easily occur in the non-slip packaging material. If the quick-setting curing resin contains more than 40 parts by weight of butyl acrylate, the anti-slip wrapping material becomes excessively flexible, so that the anti-slip wrapping material can easily tear when an external force (friction with the vehicle tire, etc.) occurs.

When the 2-ethylhexyl acrylate is contained in the quick-setting curing resin at less than 5 parts by weight, the flexibility of the anti-slip wrapping material is reduced, and cracks can easily occur in the anti-slip wrapping material. If the quick-setting resin contains more than 15 parts by weight of 2-ethylhexyl acrylate, the non-slip wrapping material may be excessively flexible and easily damaged due to external force, and the lack of weather resistance of the non-slip wrapping material may cause short- It may be discolored.

If the quick-setting curing resin contains less than 1 part by weight of N, N-bis- (2-hydroxypropyl) -p-toluidine, the curing time of the non-slip packaging material may be delayed due to lack of reactivity with the curing agent. If the quick-setting curing resin contains more than 5 parts by weight of N, N-bis- (2-hydroxypropyl) -p-toluidine, the hardness of the anti-slip package may be lowered and the yellowing Lt; / RTI >

It is preferable that such a quick-setting curable resin is contained in an amount of 17 to 27 parts by weight based on 100 parts by weight of the subject.

If the HSC resin is contained in an amount of less than 17 parts by weight, the flexibility and adhesion of the non-slip packaging material may be deteriorated and the durability of the non-slip packaging material may be deteriorated. When the hypercylinder resin is contained in an amount exceeding 27 parts by weight on the subject, the viscosity of the subject is lowered so that the aggregate (hard aggregate) described later is not projected to an appropriate level from the non-slip wrapping material and impregnated with the slip- Can be degraded.

The subject may further include at least one selected from the group consisting of a coloring pigment, a filler, a thixotropic agent, an anti-settling agent, an adhesion promoter and a hard aggregate in addition to the quick-setting resin.

The color pigment may be contained in an amount of 2 to 5 parts by weight based on 100 parts by weight of the subject. As the coloring pigment, an inorganic pigment (iron oxide pigment) or an organic pigment may be used. If the content of the coloring pigment on the subject is less than 2 parts by weight, the tinting strength may be insufficient and concealment rate may be lowered, and the weather resistance may be lowered to cause discoloration. If the content of the coloring pigment on the subject exceeds 5 parts by weight, there is an uneconomical problem because the amount of increase in concealment rate is drastically reduced.

The filler may be included in an amount of 45 to 55 parts by weight based on 100 parts by weight of the subject. The filler is used to improve the mechanical strength of the anti-slip package. The filler may be a mixture of calcium carbonate and dolomite in a weight ratio of 30:70 to 70:30 or a mixture of calcium carbonate and silica sand in a weight ratio of 30:70 to 70:30 May be used. When calcium carbonate alone is used, the abrasion resistance and chemical resistance of the non-slip packaging material may be lowered. However, when calcium carbonate is mixed with dolomite or silica sand, wear resistance and chemical resistance of the non-slip packaging material can be further improved.

If the content of the filler on the subject is less than 45 parts by weight, the mechanical strength of the non-slip packaging material may be reduced and the abrasion resistance may be greatly reduced. If the content of the filler on the subject exceeds 55 parts by weight, problems such as poor adhesion of the non-slip wrapping material and cracks in the non-slip wrapping material may occur due to insufficient adhesion of the non-slip wrapping material to the wrapped object and decrease in flexibility of the non- Can be caused.

The thixotropic agent may be contained in an amount of 0.5 to 2 parts by weight based on 100 parts by weight of the subject, and the anti-settling agent may be included in an amount of 0.1 to 1 part by weight based on 100 parts by weight of the subject. The thixotropic agent and the anti-settling agent serve to protrude the hard aggregate from the non-slip packing material to increase the sliding resistance of the non-slip packing material and to prevent the deposition of the colored pigment. Urea and clay additives may be used as the thixotropic agent and sedimentation inhibitor.

If the content of the thixotropic agent on the subject is less than 0.5 parts by weight and the content of the sedimentation inhibitor is less than 0.1 parts by weight or the content of the thixotropic agent on the subject exceeds 2 parts by weight and the content of the antifouling agent exceeds 1 part by weight, The sliding resistance of the non-slip wrapping material may be reduced, and the workability may be lowered due to an increase in viscosity.

The adhesion promoting agent may be included in an amount of 0.2 to 1 part by weight based on 100 parts by weight of the subject. The adhesion promoter improves the adhesion of the hard aggregate to the non-slip wrap to prevent the hard aggregate from falling off the non-slip wrap, thereby maintaining the slip resistance of the non-slip wrap. As the adhesion promoting agent, a material containing a phosphate ester may be used. If the content of the adhesion promoter on the subject is less than 0.2 part by weight, the adhesion improving effect may be lowered. If the content of the adhesion promoter on the subject exceeds 1 part by weight, discoloration may occur in the anti-slip packaging material, and a curing failure may be caused.

The hard aggregate is used to improve the durability, abrasion resistance and slip resistance of the anti-slip package. The hard aggregate may be included in an amount of 20 to 30 parts by weight based on 100 parts by weight of the subject. As the hard aggregate, any one or more selected from non-metal aggregate such as silica sand or sand stone having a particle size of 0.1 to 6 mm, processed aggregate, coated aggregate and metal aggregate may be used.

As the curing agent, a powdery or paste-type curing agent may be used. The curing agent may include benzoyl peroxide (BPO, benzoyl peroxide). The curing agent may further comprise a phthalate plasticizer such as dicyclohexyl phthalate (DCHP).

Such a curing agent may be mixed with the subject in an amount of 0.5 to 3 parts by weight based on 100 parts by weight of the subject. If the content of the curing agent mixed in the subject is less than 0.5 part by weight, the curing efficiency may be lowered. When the content of the hardening agent mixed in the subject exceeds 3 parts by weight, discoloration may occur in the non-slip packaging material.

(2) Method of forming non-slip packing material

A construction process for forming a non-slip wrapping material on a packaging object using the non-slip packaging material composition according to the present invention will be described. The method of forming the anti-slip wrapping material according to the present invention can be applied to any place where slip prevention is required, but is applied to a lane.

- Surface clearance step: Removes various foreign substances existing on the surface of the package object previously set in the lane. It is also possible to carry out an operation of uniformly treating the surface of the object to be packed. (See FIG. 1). This step may proceed after oil evaporation and sufficient compacting in the case of new packaged asphalt roads.

- Masking tape attaching step (sanitizing step): Attach masking tape around the wrapped object to the surface. (Refer to FIG. 2) The periphery of the package object to which the masking tape is attached is prevented from applying the primer and the anti-slip material to be described later.

- Primer Layer Forming Step: After attaching the masking tape, a primer layer is formed by applying a primer to the surface of the packaging object. (See Fig. 3)

- Formation of anti-slip packaging material: The non-slip packaging material composition according to the present invention is applied on the formed primer layer in a thickness of 0.5 to 100 mm to form a non-slip packaging material. (See Fig. 4)

Here, when the object to be packaged is a concrete road or an asphalt road with severe deterioration, adhesion of the non-slip packaging material can be improved by using methyl methacrylate, urethane or urea resin based primer.

The slip resistant packaging material composition according to the present invention may be prepared by first mixing (mixing) a hard aggregate on a subject at a construction site, and then mixing the slurry with a base.

The attached masking tape can be removed after the formation of the anti-slip wrapping material is completed.
