Description

[Detailed Description of the Invention] (Industrial Application! IIF) This invention relates to a waterproofing method, specifically concrete, mortar, concrete products, blocks, ALC boards, wood,
This relates to waterproofing methods that are essential for applying to steel materials, etc.

(Prior Art) Conventionally, as this type of waterproofing method, asphalt-based, urethane-based, sheet-based, inorganic-based, and organic-based waterproofing methods have been known.

(Problems to be Solved by the Invention) However, with this type of conventional waterproofing method, the waterproof layer also cracks due to cracks in the building structure, the adhesiveness is weak, and the weather resistance is relatively weak, so an excessively large protective layer is required. Many of them are difficult to use, are weak against external impact, or lack cold resistance, heat resistance, acid resistance, chemical resistance, etc.

In addition, we have identified issues such as construction methods that require construction to be carried out only after the moisture has completely disappeared from the substrate, methods that require long drying times between processes, methods that have problems with curing methods, and methods that make it difficult to perform detailed construction. I had it.

In addition, if a urethane-based waterproof coating is applied, it is susceptible to heat and is not strong enough to walk on.
It is necessary to form a waterproof layer with a thickness of 150 nm.
The weight was kg/m'.

Furthermore, most construction methods do not allow easy repair of aging waterproof layers or repair of water leaks. Furthermore, there are construction methods that can be used to immediately finish the waterproof layer using only waterproof mortar, and the base layer has not been considered important in the past.

On the other hand, as a result of intensive research, the inventor discovered that in the waterproofing method,
First, protect the adherend (concrete, mortar, concrete products, blocks, ALC board, wood, steel I4) and the structure with a permeable base layer, then protect with a waterproof layer on the base layer, and then take a waterproof sample of the waterproof layer. It was discovered that protection by the layer is necessary, and that it is necessary to select the appropriate material for each layer.

In other words, the base layer needs to have high adhesion to the adherend and the structure and provide complete protection.

However, although conventional primer sealers smooth the surface of the adherend and make it easier to apply a waterproof layer, they do not have a significant protective effect on the adherend.

However, the inventor used a cement structure base primer containing Portland cement, titanium dioxide, and powdered acrylic resin, and the volume ratio of the cement structure base primer containing these components was 4 to 4.5. Mix 1 liter of water to form a dry film thickness of 230 to 3 liters on the concrete surface.
When coated to a thickness of 0.00 microns and then finished with a water-based coating material, it was found that it had high alkalinity and excellent adhesive strength. Furthermore, it was found that it has excellent waterproof properties.

That is, Portland cement, titanium dioxide,
A cement structure base primer characterized by containing a powdered acrylic resin, and a volume ratio of 4 to 4.5 for a cement structure base primer containing Portland cement, titanium dioxide, and a powdered acrylic resin. 1
of water to form a dry film thickness of 230~ on the concrete surface.
It has been found that these effects can be obtained by a method of applying a primer for a base of a cement structure, which is characterized by applying the primer to a thickness of 300 microns.

Next, a waterproof layer is required to protect the base layer, but conventionally known adhesive construction methods such as sheet waterproofing and asphalt waterproofing that use adhesives that prevent vapor transmission through the adherend are This is undesirable because it causes the waterproof layer to swell. Furthermore, as a waterproof layer, it has excellent weather resistance and a temperature difference of -30
It is necessary that the material can withstand temperatures between -80°C.

On the other hand, we have discovered a waterproof coating agent that is a water-based waterproofing material, has excellent adhesive properties, provides a waterproof coating with excellent stretchability and elasticity, and also has transportability.

That is, it is a waterproofing/coating agent characterized by comprising an acrylic resin emulsion, and a plasticizer, a pigment dispersant, an antifoaming agent, and an inorganic fine powder dispersed in the emulsion.

However, since the surface of this waterproof coating agent is moist and soft, it is necessary to protect it.

On the other hand, the inventor tried an anti-slip agent characterized by mixing an anti-slip powder containing aggregate and hydraulic cement with a synthetic resin emulsion containing an acrylic synthetic resin, and found that the anti-slip agent had a thickness of 1. At around .2mm, it has a strength that is more than twice the compressive strength of mortar, has excellent waterproofness and adhesion, and also has transportability, is compatible with the above waterproof coating agent, and has a Compared to anti-slip agents whose main material is epoxy resin, their adhesion is more flexible and cooperative with the surface to be painted, and solves the problems faced by conventional anti-slip agents whose main material is epoxy resin. I found out.

That is, this anti-slip agent is characterized by being made by mixing an anti-slip powder containing aggregate and hydraulic cement with a synthetic resin emulsion containing an acrylic synthetic resin.

(Means for Solving the Problems) The present invention has discovered that by combining these primers, waterproof coating agents, anti-slip agents, etc., special effects can be produced in each application.

However, oxidative etching is not necessary. Once the surface has been cleaned, apply it to the concrete surface using a brush, roller, or spray at a rate of 2.3 square meters per liter to a dry film thickness of 230 to 300 microns. It is desirable that the surface to be applied is not so wet that water droplets will float on it, but moistening it in advance will improve the attachment force. The most desirable method of application is to use a brush or a brush with soft bristles. the"

Therefore, this primer has high alkalinity, high adhesion, waterproofness, long life in the container, and self-leveling effect, making it possible to provide a smooth surface without pinholes. If you apply waterproofing powder over it, it will become completely dense. In addition, flammability becomes low.

Furthermore, this primer allows water vapor from the adherend to pass through, but prevents moisture and gas from entering from the outside, while being permeable and further strengthens the protection of the underlying layer.

Therefore, it can be used not only as a primer coat to provide a good base for applying paint, such as areas scheduled for topcoating, areas scheduled for finishing concrete foundations, areas scheduled for decorative finishing, and areas scheduled for installation of protective material to prevent carbonization, but also as a primer coat. It functions as a protective finishing material on its own without the need for painting.

In other words, it is possible to obtain strength even if the film is thinner than conventional ones, and we have discovered a cement admixture that provides strong adhesive strength, high compressive strength, bending strength, impact resistance, abrasion resistance, and waterproofing properties. In other words, cement admixtures include water-dispersible acrylic copolymer resin emulzidine 40-76% by weight, water 20-58% by weight, antifoaming agent 0.04-1,00% by weight, and preservative.

When mixing cement and admixtures, if you want to make a strong mix, first add the cement admixture directly to the cement, sand, and aggregate in the specified amount and mix well, then add water little by little until the appropriate amount is reached. hardness. If the amount of cement admixture and water is limited, mix it with water first and adjust with the cement admixture. Construction is carried out once the concrete mortar containing cement admixture has been prepared. First, clean the base and remove impurities such as dust, grease, and leiraless. It can be applied even if the surface to be applied is damp, but if there is too much moisture, there is a possibility that the adhesive strength will be lost. If the base of the construction surface has many pores and requires surface treatment, it is desirable to apply a base coat once with a cement admixture. Since the resin component of the cement admixture has water-repellent properties, it is desirable not to expose the fresh mortar to water for at least 12 hours until the mortar is completely set.

A transparent gloss finish is applied with a roller to the concrete surface to be painted and allowed to cure at room temperature for 7 days. A beautiful painted surface was obtained that had a glossy surface and the inside of the paint film was visible.

In order to examine the physical properties, a 1 mm thick film was cut out from the painted surface.

Pencil hardness 4H Abrasion loss 28mg (Taper abrasion test, C3-17 Performed by applying 1,000g to the wheel and rotating it 1°000) Impact resistance -30F, 1n-1t) Direct 160 Indirect 160 Film flexibility 100% Modulus 7000psi (492kg/
cm'') Tensile strength: 8000 psi (562 kg/c+++'') Elongation: 200z As can be seen from these results, the transparent gloss finish according to the present invention has excellent physical properties and also passes the water resistance test.
Excellent results were also obtained in alkali resistance, ultraviolet resistance, and heat resistance tests. No reduction in gloss, mold, or moss growth due to these effects was observed.

This transparent gloss finish provides a transparent gloss finish with excellent durability, water resistance, flexibility, UV resistance, abrasion resistance, alkali resistance, and weather resistance. In addition to being a gloss finish, it can also be used as a surface protection and sealing agent for slate, brick, sandstone, unglazed tiles, paving stones, gravel, crushed stone, concrete, brick, stone, sandstone, wood, steel, etc. Suitable as a gloss finish for slate, terrazzo, gravel surfaces, unglazed tiles, paving stones, interior and exterior walls, earthen walls, plasterboard, cement mortar, foam concrete boards, precast concrete boards, etc. In other words, it vividly brings out the colors of slate, brick, etc.

Various gloss finishing agents are known that can be applied to the surface of concrete or the like to give it gloss. For example, if it is desired to give a concrete surface a metallic luster, metal powder may be applied to the concrete surface. However, conventional gloss finishing agents lack alkali resistance and acid resistance, resulting in a lack of gloss, which is a problem.

Furthermore, due to the lack of water resistance, mold and moss can grow. Furthermore, when used outdoors, it has been pointed out that the problem is that it lacks UV resistance and is prone to deterioration.
This transparent gloss finish solves these problems.
