Description

Non-slip road binder with heat shielding {Nonskid Binder with reflection quality about heat}

In the present invention, in forming the anti-skid binder, the non-slip binder reflects near infrared 780-2100 nm, which occupies half of the high energy amount of sunlight, by 80% or more to block road heat transfer by radiant heat and absorb heat on the pavement surface. It is formed to suppress the rise of the road surface temperature to improve the city's high temperature and pedestrian environment and to prevent heat accumulation in the road to prevent tropical night problem , Excellent adhesion to asphalt (road) road surface, improved wear resistance, acid and alkali resistance, improved frictional resistance and high-strength anti-skid pavement in winter, as well as low-temperature rapid (MAST) METHYL METHACRYLATE) Resin and aluminum seals of micro hollow spheres ranging in size from 30 μm to 100 μm Car and heat reflecting pigments are added to the ceramic air layer, which is a closed air layer in the binder, to optimize the heat reflection and heat resistance effects, thereby preventing heat island phenomenon in the city, as well as providing excellent durability after construction and in particular, rapid workability. It relates to a non-slip road binder having a heat shield, characterized in that to minimize the traffic control time.

In general, highways, national roads, and local roads tend to have more bent roads or downhill roads compared to speeding vehicles. In these places, the road surface is slippery, so that vehicles leave the road or roll over on curved roads. Many non-slip facilities have been used to prevent such accidents.In the past, as interest in safety accidents increased, anti-slip pavement such as ramps of road intersections, sharp curves and ramps, schools, crosswalks, etc. Non-slip facilities such as roads, parking lots, and other traffic accident areas are installed and used.

Conventional anti-slip installations are generally used in the form of:

First, the resin is applied to the road and aggregate (steel slag) is applied, and the surface is finished by compacting the surface by using a compaction roller of a certain weight. Falling, aggregate dropping progresses due to continuous impact from driving vehicles, and the wear and slip resistance of the product is remarkably lowered.When the product is used for a long period of time, dropping with the base material asphalt may proceed. do.

In addition, weather resistance is poor, and discoloration of a coating film advances rapidly, and the visibility of a product falls rapidly. In addition, by using a thick aggregate in order to increase the sliding resistance, the thickness of the coating is increased, which causes the vibration of the vehicle and the deterioration of the riding comfort.

Secondly, there is a method of painting using a thermoplastic resin. This method works by using a separate melting machine, so the workability is good, but the variety of product colors is degraded, and the visibility of the product is deteriorated due to color discoloration. do. In addition, thick aggregates such as bauxite or steel slag are used as anti-skid aggregates, so that aggregates contained in the products sink when the molten product is applied, and the resin layer covers the surface where the aggregate components are small. Phenomenon appears.

Even in this method, the aggregates drawn on the surface due to the continuous impact of the vehicle proceeds to cause environmental pollution, and the slip resistance is degraded by the surface resin layer from which the aggregates are dropped. It causes noise and decreases riding comfort.

As the second conventional method, the anti-slip agent on the pavement has been proposed in Patent No. 0171675 (Registration Date: October 21, 1998).

That is, the anti-slip agent for roads of the prior art patent No. 0171675 is 50% or more of steel slag or bauxite, 16-18% of resin ester, 10-13% of low density polyethylene, 2-4% of activated carbon, rubber 2 ~. 4% and 10 ~ 20% of the fillers of stone powder and enamel silicate are heated and melted at 210 ~ 250 ℃ to form an anti-slip agent on the pavement, and apply this anti-slip agent to the road surface with a uniform thickness to make flat work. It is to be cured at room temperature for 10 to 15 minutes.

The conventional anti-slip agent for the road, when the product is applied, the aggregate component of the bauxite, which is a mineral, is settled to the floor by the load, so that the resin component surrounds the aggregate surface, so that the sliding resistance is relatively low, and the resin surface with time passes. If this wear occurs, the settled aggregate is drawn to the resin surface and shows slip resistance, but the aggregate component is dropped by continuous impact and abrasion caused by vehicle traffic, and loses its function as an anti-slip agent. It acts as a factor that causes a decrease in reliability of the product as an inhibitor.

As such, conventional binders used for non-slip purposes are currently used in both thermosetting resins and thermoplastic resins, and thermoplastic resins dissolve the binder by heating and adhere to the road surface. However, it requires a lot of equipment for repair, and as the thermosetting resin, epoxy, polyester and acrylic emulsion resins are widely used.

Therefore, the epoxy-based binder has a low curing rate, there is a disadvantage of discoloration in the case of color after construction vulnerable to ultraviolet rays, and the polyester-based disintegration of aggregates caused by the deterioration of adhesion and strong hardness rather than cracking Acrylic emulsion is poor in adhesiveness and durability due to mechanical property degradation, and the current non-slip packaging has one purpose of being non-slip.

The present invention is to solve the above-mentioned problems, the technical gist of the present invention in forming a non-slip binder, the non-slip binder by reflecting 80% or more near infrared 780-2100nm that occupies half of the high energy amount of sunlight To separate road heat transfer by radiant heat and to separate heat shielding additives to prevent heat absorption on the pavement surface, it is formed to suppress the increase of the road surface temperature, thereby improving the high temperature generation and walking environment of the city. It is formed to solve the tropical night problem by preventing heat accumulation on the road, and it has excellent adhesion to asphalt (road) road surface, improves abrasion resistance, acid resistance and alkali resistance, improves friction resistance and high-strength anti-skid pavement work in winter.

At this time, when the total composition ratio of 1) to 4) mixed with the composition is 100% by weight, BPO (500: BENZOYL PEROXIDE), which is 2-7% by weight of a peroxide curing agent, is mixed and then 30 at -15-30 ° C. It is preferable to form a non-slip layer during pavement by curing for ~ 50 minutes.

<Example>

In general, MMA resins have a molecular weight of 20,000 to 200,000 vinyl polymers or copolymers, and as the diluent, methacrylic esters containing unsaturated groups are mainly used.

At this time, the additives include tertiary amines, cobalt, vanadium, and the like as curing accelerators for promoting initiator decomposition. Peroxides (organic peroxides BPO) are commonly used as initiators or curing agents.

The MMA resin composition uses a monomer having a high hardness among the monomers containing an unsaturated group, thereby preventing occurrence of elongation lowering and forming a soft and soft elongation similar to summer asphalt elongation.

At this time, in order to make an anti-slip binder using excellent modified MMA resin, polybasic acid and polyhydric alcohol are condensed at 200 ° C. to 220 ° C. for 4 hours to 6 hours, and then a polymerization inhibitor is added thereto.

The alkyd phase obtained in the above method is usually added in an amount of 0.001 to 0.1% by weight to 100% by weight of hydroquinone, toluhydroquinone, butylcatechol pyrocatol and the like as a polymerization inhibitor.

At this time, tertiary amines such as dimethylaniline, diethylaniline, dimethylparatoludine, and phenyl diethanolamine may be used as accelerators in order to obtain a room temperature reactive resin composition. Other metal salts such as cobalt, manganese, and the like may be used.

In addition, as the heat shielding hollow body pigment 200, 6% by weight of the selected ones of the burmeklai, pearlite, obsidian expanded soil, and the bubble glass hollow body are added as the hollow body, and the color pigment 300 for coloring is shielded. In order to maximize the effect, use a mixture of 6% by weight of colored pigments and inorganic pigments pretreated with aluminum or zirconium.
