The alkali recovery heat-insulating and waterproof sheet according to the present invention comprises: a center substrate made of a polyester nonwoven fabric; And 45 to 65 wt% of straight asphalt, 10 to 15 wt% of styrene butadiene styrene (SBS), 15 to 20 wt% of process oil, A rubber asphalt layer composed of 10% to 20% by weight of heat insulating material and filler; (38% by weight to 54% by weight of cationic emulsified asphalt), 10% by weight to 12% by weight of styrene butadiene styrene (SBS) as a polymer modifier, 15% by weight to 18% by weight of process oil, By weight, 2% by weight to 3% by weight of tackifier, 4% by weight to 8% by weight of water-soluble lithium silicate, 1% to 3% by weight of thermoreversible polymer, 5% , An antifreezing agent of 5 to 7 wt%, and an antifouling agent and an acidity regulator of 2 to 4 wt%.
Hereinafter, the constitution of the rubber asphalt layer, the center substrate, and the adhesive waterproof layer constituting the alkali recovery heat-insulating and waterproof sheet according to the present invention will be described in order.
First, the above-mentioned central base material is a polyester nonwoven fabric which is usually used as a center base material of a waterproof sheet. In the case of a waterproof sheet, in the case of a waterproof sheet, The present invention overcomes this problem as a waterproof material impregnated on a base material, and utilizes a core material of various materials for improving the tensile strength and durability at the same time as forming the thickness. In the present invention, polyester nonwoven fabric is adopted.
On the other hand, a rubber asphalt layer is formed on the upper surface of the center substrate. Straight asphalt in the composition of the rubber asphalt layer is used for increasing the adhesive strength of the waterproof sheet. 3 and AP-5. For example, a case where the penetration degree at 25 DEG C, 100 g, 5 seconds, 0.1 mm is 80 to 100, is referred to as AP-3, and a case where the penetration degree is more than 60 and 80 or less is referred to as AP-5.

If the content of the straight asphalt of the present invention exceeds 65% by weight, the waterproof sheet's adhesion and cold resistance deteriorate. If the content of the straight asphalt is less than 45% by weight, the quality of the product deteriorates and the cost increases
Styrene butadiene styrene (SBS), which is a polymer modifying material in the composition of the rubber asphalt layer, can improve the adhesion by improving adhesion, elasticity, flexibility, tensile strength and compatibility between raw materials, If the content is less than 10 wt% based on the total weight of the sheet, the adhesive strength is lost. On the contrary, if the content is more than 15 wt%, the viscosity increases due to the increase of the asphaltene content, but the adhesive strength is rather reduced. It is inconvenient and the adhesive force is lowered at low temperature, and the cost of the product is increased due to the excessive addition of high-SBS.
Particularly, when styrene butadiene styrene (SBS), which is a polymer modifying material, is mixed with the stearate asphalt, the asphalt secures the rubbery elasticity, and the maltene component in the asphalt is absorbed by the modifying material, Is expanded 5 to 7 times.
Also, when a modifier is mixed with straight asphalt, the modifier is dispersed in the asphalt initially, but when the amount of modifier is increased, the volume is increased by expansion of the modifier.
The process oil in the composition of the rubber asphalt layer is a paraffinic viscoelastic oil and is excellent in heat resistance and temperature-sensitive property due to the addition of styrene butadiene styrene (SBS) It is mixed in the range of 15% by weight to 20% by weight based on the total weight of the rubber asphalt layer. If it is added in an amount of 15% by weight or less, the adhesive strength and the thermosensitive property are lost, When added, the adhesive strength is partially reduced and only the cost of the product is increased.

When SBS Over-addition only increases the cost of the product.
The process oil is a paraffinic viscoelastic oil having excellent low temperature flexibility, an increase in adhesive strength, and a low viscosity. The process oil is a styrene butadiene styrene (SBS) Which is excellent in heat resistance and temperature-sensitive property and is composed of a high molecular weight and is suitable for processing work at a high temperature, has low evaporation loss, is excellent in cold resistance, generates little heat and has an aromatic compound and a saturated hydrocarbon- Waterproofing sheet and coating material based on asphalt, and is mixed in the range of 15% by weight to 18% by weight based on the total weight of the adhesive waterproof layer, 15% by weight or less, By weight, the adhesive strength and the thermosensitive property are lost. On the contrary, when the content is 18% by weight or more, Only the cost of the product will rise.
Among the compositions for forming the adhesive waterproof layer according to the present invention, the tackifier is very stable even under exposure to ultraviolet rays, has self-adhesive force, and the adhesion increases as the molecular weight and viscosity increase, and the chlorine and sulfur content It is extremely low in purity and has no toxicity, is chemically stable, and is not easily oxidized by light or heat.
In the present invention, since polybutene containing the above characteristics is added, the disadvantages such as falling down at a high temperature which has been pointed out as a conventional disadvantage, oxidation of a product by ultraviolet rays upon exposure, Alkali recovery film is mixed in the range of 2 wt% to 3 wt% based on the total weight of the waterproofing coating material of alkali, and when it is added in an amount of less than 2 wt%, a small amount of high-molecular polybutene is added to reduce the cost, If it is added in an amount of 3% by weight or more, the cost increases due to the high end of the polybutene, and it becomes hard at a low temperature, resulting in inconvenience of construction and is easily oxidized by ultraviolet rays, heat, .
The water-soluble lithium silicate in the composition for forming an adhesive waterproof layer according to the present invention is an alkaline remover, which restores the alkalinity of the neutralized concrete structure to inhibit and prevent corrosion of the steel by the neutralization of concrete, and prevents the concrete structure from contacting with atmospheric carbon dioxide as the conversion of water and calcium carbonate, to prevent from being deteriorated, and the + 1-valent lithium present in the lithium silicate (Li 2 O-nSiO 2 -xH 2 O) replacing the CO 3 by ionic bonding, the concrete is neutralized progressed The pH of the structure is elevated to 11 to 12 to make strong alkalis and crosslinked with the free cement component in the concrete structure through ionic bonding, thereby increasing the mechanical strength of the surface and the interior of the concrete.
The water-soluble lithium silicate is preferably added in an amount of 4% by weight to 8% by weight based on the total weight of the adhesive waterproof layer. When less than 4% by weight is added, the alkalizing effect of the concrete structure is lowered, If it is exceeded, the alkalizing effect is improved to some extent, but the effect is not large and only the cost of the product is raised.
In the present invention, a thermally reversible polymer is used to convert the mixture containing a cationic emulsified asphalt into a gel, as described above. In the present invention, a thermo reversible polymer, polyindolocabazole, is employed, and the thermostable polymer, polyindole The content of rocavazol is preferably 1% by weight to 3% by weight based on the total weight of the adhesive waterproof layer, and if it is outside the above range, the viscosity becomes too high and gelation does not occur.

If it is less than 5% by weight, the insulative effect is insufficient. If it exceeds 7% However, the increase of the closed pores may cause an increase in the content due to the addition of the antimicrobial agent, resulting in an increase in the cost of the product due to the expensive encapsulant.
According to the present invention, the char of the adhesive waterproof layer composition can be used as a filler for heat insulating materials, and can be used to add odor removal and antimicrobial properties to synthetic rubber. Charcoal is composed mainly of carbon and minerals and mixed with synthetic rubber. It is easy to absorb microorganisms and to absorb positron which is the cause of odor.
The char is preferably added in an amount of 2 to 3 wt% based on the total weight of the adhesive waterproof layer. If the char is less than 2 wt%, the adiabatic effect is insufficient. If the char is more than 3 wt% One adhesive force and adhesive force are lowered.
In the composition of the adhesive waterproof layer according to the present invention, waste rock powder is added as an anti-freezing agent, and this waste rock powder also plays a role as a gelling time control and a heat insulating material.
The abrasive powder is generally inexpensive, improves the bonding force between various polymers, and slows the gelling speed to allow the alkali recovery agent to penetrate into the core of the concrete. The weight of the abrasive powder is, based on the total weight of the adhesive waterproof layer according to the present invention 5% by weight to 7% by weight is preferably added.
When the cryoprotectant is added in an amount of less than 5% by weight, the effect is insufficient and only the specific gravity is increased. When the cryoprotectant is added in an amount exceeding 7% by weight, the cost reduction effect is caused. do.

The adsorbent absorbs gas or moisture, And 2% by weight to 4% by weight based on the total weight of the adhesive waterproof layer according to the present invention.
If the content of the antifouling and acidity regulator is less than 2% by weight, the effect is insufficient. If the antifouling and acidity regulator is added in an amount of more than 4% by weight, the price reduction effect is caused but the adhesive strength is decreased and the effect is insignificant.
As described above, the alkaline recovery adiabatic waterproofing sheet according to the present invention has a long-term alkali restoring force and permeability, and is applied to the concrete structure to greatly improve the alkali recovery and durability of the concrete structure.
In addition, the adhesive water-repellent layer of the alkaline recovery adiabatic water-repellent waterproof sheet according to the present invention is combined with lithium silicate which imparts alkaline recovery force, and insulide, charcoal and waste rock powder are added in triple to improve the heat insulating performance, It can maintain antifouling property. It has excellent self-restoring ability because it is in a sticky state.
