Description

No-accident, eco-friendly waterproof, moisture proof construction and cold insulation method using flame retardant polymer insulation

The present invention relates to the construction of an accident-free waterproof, moisture-proof, and insulated structure of a cold storage facility. To prevent human injury, fire, and explosion caused by a general organic solvent gas, an emulsion Epoxy Resin, a solvent-free epoxy polyurea cured Resin, is installed on an inner wall surface. To prevent fire or explosion by organic solvents, and flame retardant polymer insulation (polyurethane) construction (spray injection), construction of flame retardant polyurethane polymer compound prevents fire from spreading and spreading to large fires in case of partial fire. The present invention relates to a method for constructing an environment-friendly cold storage facility to reduce human injury.

Styrofoam rock wool board and polyurethane foam in the interior of the cold storage facility Blocks moisture and moisture from the outside during the construction of the polyurethane foam for waterproof and moisture proof construction. U) Waterproofing and epoxy waterproofing have been applied to the inner wall and insulation has been applied to general cold storage.

There are existing low-temperature freezer warehouses or freezer warehouse construction methods, and patented "10-1999-0021842" freezer warehouse insulation structure, but the existing Dongwon Freezer Warehouse Fire (2007-001) In the same way as Icheon Freezer Warehouse Fire (2008), it is a cold storage cold storage method in the same way as the fire caused by fumigation of organic solvents and explosion caused by large accidents caused by waterproofing polyurethane (P / U). It became a social problem

Thus, my patent "No. 10-0912354" has been registered for the accident-free construction method of the special insulation structure for refrigeration and refrigeration, but in the construction method of the solvent-free polymer compound waterproof, moisture-proof construction and flame retardant polymer insulation (polyurethane) construction method Solvent-free polymer compound waterproofing takes a lot of time on site work and almost impossible to work with brushes or sprays, resulting in high labor costs and a small amount of diluent when mixing polymer resins. Cold storage method was developed for the purpose of securing and convenient work and economical saving.In the case of finishing galvalume (flat, corrugated board) after wood installation, cold air inside and outside with anchor bolt is fixed when fixing finishing materials after general wood construction. There are many problems such as moisture generated in the fixed plate wood and repaired by corrosion of the wood. Mold has been found to harm the clean environment of cold storage facilities.

In case of anchor bolt construction of this design, internal and external temperature is blocked by using insulation P / P joint anchor bolt or P / E joint anchor bolt, and in case of timber, it prevents corrosion by blocking moisture penetration by using domestic timber. After the fixed joining of the waterproofing wood, 30mm finish fire retardant polymer insulation construction to increase the bonding strength of the fastening waterproofing wood and reduce unnecessary space.

(1) In the case of waterproof and moisture proof construction materials, water-soluble Epoxy Resin can be used for various applications with low viscosity so that it can be used as an air race, roller, or brush. In order to prevent construction defects, and in the case of a very large cold storage facility, the solvent-free epoxy and polyurea curable resins are mechanically constructed with a high-pressure air race to increase the speed of work and to enable roller or brush construction. Constructed to be safer and more economical by waterproofing and waterproofing urea

(2) When constructing insulation material, it is constructed to be safe insulation construction by blocking insulation of insulation of cold storage facility and diffusion of fire in case of fire by performing perfect insulation construction using flame retardant polymer insulation (flame retardant polyurethane).

(3) By using fixed anchor bolts for thermal insulation P / P and P / E bonding, internal and external air temperature is not transmitted to prevent moisture or frost on the exterior wall or interior joining wood. By covering two-thirds, the fixed wood is fixed more firmly without shaking when the galvalume (flat, corrugated sheet) or steel plate is joined to prevent defects from occurring.

(4) Safety and cleanliness of cold working construction by using a method to solve the above problems by applying transparent or colored solvent-free mold-proof mold resin coating to prevent sexual love, rust, and mold formation when finishing finishing material galvalume (flat, corrugated sheet) Invented for the purpose of maintenance

In the case of another flame-retardant polymer insulation injection method, it is designed to inject flame-retardant polymer insulation (polyurethane) into the injection space after emulsifying Epoxy waterproofing material, solvent-free curable polyurea waterproofing, and moisture-proof coating for the purpose of external waterproofing and moisture proofing. It is a construction method that is configured not to reduce the insulation performance due to safety, fire protection, and moisture.

As mentioned above, water-proof and moisture-proof construction resin which can cause fire, explosion, and human injury can be reduced by using emulsion Epoxy Resin Coating and non-solvent-curable polyurea polymer resin in epoxy to reduce the risk of organic solvent and improve workability. Fire retardant using polyurethane flame retardant polymer (Polyurethane) is used, and wood joining bolt is blocked by internal and external temperature by using thermal insulation anchor bolts (P / P, P / E). Corrosion by moisture is prevented by the use of waterproof wood for fixing, and it is a construction method that does not cause mold form and sexual love by coating solvent-free mold resin on the outside of galvalume when galvalume (flat, corrugated sheet) construction is perfect. It was configured to be safe and safe construction.

1st emulsion Epoxy resin, solvent-free epoxy, polyurea coating prevents the risk of fire or explosion caused by fume vapor when waterproofing and moisture proof construction, and complements the workability to work with Laura, brush, and high pressure air race equipment for waterproof and moisture proof construction. Galvalume-bonded construction timbers are made of water-resistant wood to prevent moisture or despair when the door is opened and closed so that there is no corrosion and galvalume (flat, corrugated sheet) joint bolts The thermal anchor bolt is used to block the inflow and outflow of internal and external temperatures, and to prevent mold from using mold-resistant mold that does not rust and prevent frost when using internal galvalume (flat or corrugated sheet) or general steel sheet. It is a construction method invented so as to be a clean, environmentally friendly cold facility when using.

It is composed of emulsification Epoxy Resin, solvent-free epoxy and polyurea curable resin, which is not easy to be installed in the field.It is constructed to be waterproof and moisture-proof.It is constructed without flame, fire and explosion by fire retardant polymer insulation (polyurethane). It is easy to work, and economical, toxic and flammable organic solvents are constructed with an emulsion-epoxy solvent-free resin so that safe cold construction and clean environment-friendly cold storage facilities are maintained.

As shown in Fig. 1, emulsion epoxy waterproofing and moisture proofing is applied to the con, c (1) surface of the inner wall of a special structure for cooling purposes, and it is easy to occur when using a curable resin (2a) in solvent-free epoxy polyurea. Isocyanate compound, which is a high-molecular compound with flame retardant, is added to prevent cold, explosion, and human injury caused by volatile fumes in advance, and to be cold and flame-retardant polymer insulation construction after the first stage of curing. 20 to 40% [30] of polymethylene diphenyl isocyanate (MDI) having an inertia index of 2.4 to 2.8 [2.6] and polyol having an added value of 450 to 500 KOH / g [480] of glycerol and propylene glycol in the %] Ethylene oxidation to 10-30% [20%]% by weight of sorbitol polyol having a hydroxy value of 460-520 KOH / g [480] by adding glycerin and flohylene glycol to the weight ratio and scrooge, and bromine group-substituted glycerin A mixture of 10 to 30% [20%] of a polyester polyol having a hydroxyl value of 300 to 350 KOH [320] KOH / g obtained by addition of water and floppyene oxide, and a reaction catalyst of 0.1 to 3% of H 2 O and 0.5 to surfactant 100% of the resin containing 5% by weight, 5 to 10% by weight [8%] of flame retardant, and 15 to 25% by weight of foaming agent is mixed by spraying or injecting with a high-pressure air race foaming machine. After hardening in the machine, the flame-retardant polymer insulation layer (3) is formed by adhesive spraying from the surface of the construction after about 1 to 5 seconds and starts to foam. At this time, it should not exceed 30mm during the first primary construction.

Due to the nature of cold construction, when the construction is over 50 ~ 80mm, poor adhesion, resin foams and wrinkles may occur, which may cause lifting parts or adhesion and cracks.

Cold-retardant flame-retardant polymer insulation construction is sprayed 3 ~ 8 times based on 50 ~ 300mm depending on the type, and 50% after 100mm construction and after attaching crack prevention mesh (steel, P / E) (4) The remaining 50% should be applied to prevent cracking of the thermal insulation layer during curing, shrinkage and expansion, and the insulation wood (10) is to be insulated anchor bolts (P / P, P / E) (11), leaving the remaining 30mm insulation layer. After fixing it with water, it should be sprayed to cover more than 의 of the waterproofing wood (10) to complete the fixation and reduce the volume reduction. Type of insulation anchor bolt (11) should be constructed to block the temperature inside and outside with [P / P] anchor or [P / E] anchor which can block heat. The first waterproofing and moisture proof construction of cold insulation construction process to block moisture After cold insulation of the second flame retardant insulation, when constructing waterproof wood for joining [P / P] anchor bolt or [P / E] anchor bolt, the insulation wood (11) can block the conduction heat.

After the above process, after the construction, check the protruding part and the indentation part. After the third process, the flat process is carried out. Then, the fourth process is the joining process of joining the chemical plaster (5a) or galvalume (flat, corrugated sheet) (5) Do it.

In this way, when the 1, 2, 3, 4 process is completed, a solvent-free resin is constructed as a finishing material to complete and finish the rust, frost, and mold prevention coating (6).

At this time, after the cold construction by the 5th process configured to be coated with transparent or designated color, give forced ventilation or evaporation time to remove gas that may occur during work.

As another example of FIG. 4, the flame retardant polymer insulation (50-300 mm) is injected into the concrete wall surface by an injection method after the emulsion Epoxy Resin (2) or the solvent-free polyurea waterproof and moistureproof (2a). When installing the external racking (100), the insulation line 20 is installed to perfect the fixing of the wall. Later, build a brick with a height of 1 ~ 1.2m and construct it by injecting flame-retardant polymer insulation into the space.In addition, after stacking, the final injection is made by drilling injection holes in the wall.

After fixing the galvalume (flat, corrugated sheet) (5) with the injection fixing finish material, the cold insulation construction is performed by injecting a flame-retardant polymer insulation material into the space.

It is a method of constructing a cold insulation facility that is easy to maintain and perfect as a thermal insulation cold insulation by reducing construction space and good aesthetics by injecting construction.
