Description

Non-slip packaging composition and construction method using the same {PAVEMENT COMPOSITION FOR NON-SLIP AND CONSTRUCTING METHOD USING THEREOF}

The present invention relates to an anti-slip pavement composition with improved slip resistance and adhesion and advantageous for partial repair work, and a construction method using the same.

An appropriate speed is controlled and maintained by friction between tires of the vehicle and the road surface while the vehicle is driving on the road. However, in sharp curve areas, downhills, and roads with a lot of vehicle traffic, the slip resistance of the road surface is lowered and vehicle slippage may occur, so anti-skid pavement is made. In addition, anti-slip pavement is used in intersections, children's protection areas, and elderly protection areas, where slip accidents are common, to increase friction and prevent slipping even when making a sudden stop.

Such an anti-slip packaging material is made of a mixture of various components. For example, Korean Patent Registration No. 770605 has a method of using an epoxy resin, but conventional anti-slip pavement using an epoxy resin system has high hardness, such that the construction surface is easily damaged during vehicle operation, etc., and has poor adhesion to asphalt or concrete. There was a disadvantage that partial repair work was disadvantageous. On the other hand, as in Korean Patent Registration No. 0752050, anti-slip packaging materials using MMA alone or by mixing various resins with MMA as a main component are also known, but durability problems such as cracks and adhesiveness problems have not been solved.

In this embodiment, by using a polymer paste having a special mixing ratio, abrasion resistance, slip resistance, and adhesive strength are improved and drying time is reduced to provide a non-slip pavement composition capable of rapid construction and a construction method using the same.

An anti-slip packaging composition according to an embodiment includes 700 to 800 parts by weight of a first resin mixture including a filler; 40 to 60 parts by weight of a second resin mixture including a binder; 50 to 70 parts by weight of limestone; 30 to 50 parts by weight of a pigment; and 80 to 100 parts by weight of silica sand.

Preferably, the first resin mixture includes 30 to 40 parts by weight of quartz, 20 to 30 parts by weight of dolomite, and 10 to 20 parts by weight of limestone, 1 to 10 parts by weight of methyl methacrylate (MMA), maleic anhydride, phthalic anhydride, and adipic acid. acid), 1 to 10 parts by weight of one or more resins selected from the group consisting of ethylene glycol and diethylene glycol polymers.

Preferably, the second resin mixture may include 30 to 40 parts by weight of methyl methacrylate, 5 to 10 parts by weight of n-butyl acrylate, and 50 to 60 parts by weight of polyester.

Preferably the pigment may be red ferric oxide.

Preferably, it is prepared by first mixing the first resin mixture and the second resin mixture, and then adding pigment, silica sand, and limestone, and the mixing temperature may be -5 degrees to 40 degrees.

An anti-slip pavement construction method according to another embodiment includes: (1) mixing and preparing the anti-slip pavement composition of claims 1 to 5; (2) applying a primer to the road; and (3) applying the anti-slip pavement composition prepared in step (1), the aggregate, and the curing agent to the road to which the primer is applied.

Preferably, the primer is MMA (methyl methacrylate) 40 to 50 parts by weight; and 30 to 40 parts by weight of at least one component selected from the group consisting of maleic anhydride, phthalic anhydride, adipic acid, ethylene glycol and diethylene glycol polymer.

Preferably, the curing agent is phthalic acid dicyclohexyl ester (Phthalic acid dicyclohexyl ester) 50 to 60 parts by weight; and 50 to 60 parts by weight of benzoyl peroxide.

The non-slip packaging composition provided in the present invention realizes excellent initial strength by using a polymer paste having a special mixing ratio, improves abrasion resistance and slip resistance, and provides a non-slip packaging material with fast drying time and high adhesive strength. In addition, partial repair work is advantageous by using polymer cement.

According to the anti-slip pavement construction method provided by the present invention, it is possible to implement excellent flatness, visibility, high slip resistance, etc., while enabling rapid construction and hardening, enabling economical construction.

In the following, embodiments of the present invention are described in detail. Various changes may be made to the embodiments described below.

In this specification, the terms "comprise" or "having" are intended to designate that a feature, number, step, operation, component, part, or combination thereof described in the specification exists, but it should be understood that the presence or addition of one or more other features or numbers, steps, operations, components, parts, or combinations thereof is not excluded in advance.

Unless defined otherwise, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the embodiment belongs. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the related art, and are not interpreted in an ideal or excessively formal meaning unless explicitly defined in the present application.

In addition, in describing the embodiments, if it is determined that a detailed description of a related known technology may unnecessarily obscure the gist of the embodiment, the detailed description will be omitted.

Non-slip packaging composition

According to one embodiment of the present invention, 700 to 800 parts by weight of the first resin mixture including a filler; 40 to 60 parts by weight of a second resin mixture including a binder; 50 to 70 parts by weight of limestone; 30 to 50 parts by weight of a pigment; and 80 to 100 parts by weight of silica sand.

The first resin mixture may serve as a filler including a mixture of quartz, dolomite, and limestone, and may be mixed with one or more resins selected from the group consisting of methyl methacrylate (MMA), maleic anhydride, phthalic anhydride, adipic acid, ethylene glycol, and diethylene glycol polymer.

When 30 to 40 parts by weight of quartz, 20 to 30 parts by weight of Dolomite, and 10 to 20 parts by weight of limestone are mixed and used in the first resin mixture, the abrasion resistance and durability of the non-slip paving material can be effectively increased.

Meanwhile, quartz, dolomite, and limestone are mixed with 1 to 10 parts by weight of methyl methacrylate (MMA) and 1 to 10 parts by weight of one or more resins selected from the group consisting of maleic anhydride, phthalic anhydride, adipic acid, ethylene glycol, and diethylene glycol polymer to form a first resin mixture. can

The second resin mixture may include 30 to 40 parts by weight of methyl methacrylate, 5 to 10 parts by weight of n-butyl acrylate, and 50 to 60 parts by weight of polyester. Methyl methacrylate is a monomer with a high transition temperature and n-butyl acrylate is a monomer with a relatively low transition temperature, and slip resistance increases when they are mixed with polyester at a ratio of 3:1 to 8:1. If the ratio of methacrylate is higher than that, there is a problem of excessive hardening, and if it is lower than that, it cannot have appropriate hardness and slip resistance is lowered.

Limestone (calcium carbonate) preferably contains 50 to 70 parts by weight. If less than 50 parts by weight is added, there is a problem of weakening the adhesion of concrete, and if more than 70 parts by weight are added, there is a problem that the drying time is increased and the durability is weakened. Conventionally, a certain amount of calcium carbonate was used as a filler, but in the present invention, in addition to the limestone included in the first resin mixture including the filler, after mixing the first and second resin mixtures, 50 to 70 parts by weight of limestone was additionally added to realize an economical and non-slip packaging material with improved adhesion.

In the case of the conventional anti-slip packaging composition containing MMA and thermoplastic resin in an epoxy resin, compared to the present invention, abrasion resistance and adhesiveness are weak, and it is disadvantageous to partial repair work, and is expensive and economical.

The anti-slip pavement composition proposed in the present invention is prepared by first mixing the first resin mixture and the second resin mixture and then adding pigment, silica sand, and limestone, and the mixing temperature may be -5 to 40 degrees.

In this way, by mixing and using limestone, pigment, and silica sand in a resin mixture mixed in a special ratio, it is possible to realize an excellent initial strength, excellent abrasion resistance, and a non-slip paving material with increased adhesion to the existing pavement surface. In addition, partial repair work is advantageous by using such a polymer cement.

By using red ferric oxide as the pigment, it is effective in securing visibility and the color retention period can be increased.

Various types of silica sand, such as dry sand, silica sand No. 2, silica sand No. 4, and silica sand No. 6, can be mixed and used in various ratios depending on the nature and purpose of the road to be applied.

Meanwhile, depending on the embodiment, volcanic soil may be further included, and the deodorizing effect may be maximized by further including volcanic soil. In addition, a curing agent, an aggregate, a reinforcing agent, and a softening agent may be further included. The curing agent may include phthalic acid dicyclobexyl ester and dibenzoyl peroxide in a ratio of 1:1, and the reinforcing agent may include 70 to 80 parts by weight of diphenyl methane diisocyanate. Meanwhile, methyl methacrylate may be used as the softening agent.

After applying the primer at 0.5 to 0.8 kg/m ² once in the field, the prepared anti-slip pavement composition, aggregate and curing agent are applied, and then surface treatment is performed using a roller. Curing for about 3 hours will complete the construction.

40 to 50 parts by weight of methyl methacrylate (MMA); and 30 to 40 parts by weight of at least one component selected from the group consisting of maleic anhydride, phthalic anhydride, adipic acid, ethylene glycol and diethylene glycol polymer. The curing agent is phthalic acid dicyclohexyl ester (Phthalic acid dicyclohexyl ester) 50 to 60 parts by weight; and 50 to 60 parts by weight of benzoyl peroxide.

The anti-skid pavement compositions of Example 1 and Comparative Examples 1 to 7 were laid on a 400 mm × 200 mm × 50 mm asphalt plate with an asphalt surface in a thickness of 5 mm. After running for 3 hours while spraying water at a turntable speed of 10 km/h using an abrasion test facility, the abrasion rate was measured after rotating again at 60 km/h in a dry state.

The slip resistance was measured according to KS F 2375 using the test piece after the abrasion resistance test.

Adhesion strength was determined according to the method specified in KS F 2386, in which specimens were manufactured and tested in a laboratory. After curing the specimen at room temperature for 12 hours, the tensile adhesive plate was mounted in a tensile tester and tested while applying hydraulic pressure at a rate of 0.1 MPa/s. Tensile adhesion was measured at three locations for one sample. The adhesive strength was expressed as the average value of three specimens, and was calculated according to the following formula and rounded down to one decimal place.
