DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the overall structure and operation of a bottom polishing method using a ceramic coating agent according to the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best possible way And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention. Therefore, it should be understood that the embodiments described herein and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and that various equivalents and modifications may be substituted for them at the time of the present application shall.

FIG. 1 is a flow chart showing a process sequence of a bottom polishing method using a ceramic coating agent according to the present invention.

The bottom polishing method using the ceramic coating agent according to the present invention mainly comprises a bottom surface grinding step, a metal diamond pad grinding step, a permeable surface strengthening agent processing step, a resin pad grinding step and a ceramic coating agent application step.

If not,

Firstly, in the bottoming step, unnecessary facilities and electric wires are removed from the bottom of the concrete to be polished.

Metal diamond pad grinding step

Next, the concrete surface is ground with 2.5 to 3.5 mm using a metal diamond pad # 30.

This step is to remove or remove the existing finishing material when the concrete finishing material is applied. In the case of the new put-on concrete without finishing material, it is necessary to remove the laitance from the surface of the new concrete, , Thereby maximizing the durability of the concrete floor coated with the finishing material. Therefore, the grinding is performed at a depth of 2.5 to 3.5 mm using a metal diamond pad # 30. The grinding is performed 1-2 times according to the grinding result, and if there is a key stone on the floor, it is removed.

Then, using a more precise metal diamond pad # 80, the concrete floor is ground to a depth of 0.4-0.6 mm. This process is used to even out the floor and to fine-tune the fine scratches. We conduct it. After grinding, remove fine dust remaining on the concrete floor by using a high-pressure vacuum cleaner or a wet sweeper as necessary.

Permeable surface reinforcement treatment step

Next, to strengthen the bottom surface of concrete, a permeable surface strengthening agent and water are mixed in a ratio of 1: 1 to 3: 3, and the concrete is infiltrated for 40 to 60 minutes. Apply using an iris, a high-pressure atomizer or a rubber plunger. Ensure that no toughening agent remains on the surface of the floor.

The permeable surface strengthening agent is used for plugging concrete cracks and pinholes during concrete pouring and curing, so that the concrete floor surface becomes more integrated and firm as a whole, and secondary contamination that can come from external factors (mainly water, oil, etc.) It is possible to maximize the resistance.

Wherein the permeable surface enhancer comprises 60 to 70 parts by weight of a solvent; 10 to 40 parts by weight of one silicate-based compound selected from the group consisting of sodium silicate, potassium silicate, lithium silicate and calcium silicate; 0.1 to 3 parts by weight of a hydroxybenzophenone-based or benzotriazoles-based compound; And 0.1 to 1 part by weight of an amine light stabilizer (Hindered Amine Light Stabilizer) (HALS).

As the solvent used for the permeable surface strengthening agent, purified water can be suitably used, and the silicate-based compound is used in an amount of 10 to 40 parts by weight of any one compound selected from sodium silicate, potassium silicate, lithium silicate and calcium silicate.

The ultraviolet absorber, which is one of the ultraviolet stabilizers, absorbs ultraviolet rays (UV) from the outside and converts the ultraviolet rays to infrared rays, Is released to the outside to suppress the decomposition of the composition by ultraviolet rays, and it is preferable to absorb ultraviolet rays having a wavelength of about 250 to 400 nm. Therefore, since the ultraviolet absorber inhibits the composition from being decomposed by ultraviolet rays, the light resistance and the like of the composition can be improved.

The ultraviolet absorber may be any of those known in the art, but is preferably a hydroxybenzophenone-based or benzotriazoles-based ultraviolet absorber. TINUVIN 1130 manufactured by CIBA Co., Is more preferable.

It is preferable that the ultraviolet absorber is about 0.1 to 3 parts by weight based on the total weight of the composition. If the amount of the ultraviolet absorber is less than about 0.1 parts by weight, the ability of the ultraviolet absorber to absorb ultraviolet light may be significantly reduced, and it may be difficult to protect the composition from ultraviolet light. The activity of the photoinitiator may be inhibited and the curing of the composition may be hindered.

The amine light stabilizer (HALS), which is one of the ultraviolet light stabilizers, plays a role of stopping the chain photooxidation reaction because the free radicals in the composition already formed by photolysis by ultraviolet rays decays the free radicals so as not to cause a chain reaction do. Therefore, the light resistance of the composition can be improved because it inhibits decomposition of the composition by free radicals and protects the surface of the composition.

The amine photostabilizer may be any of those known in the art, but may include bis (1,2,2,6,6-pentamethyl-4-piperidyl) sebacate and methyl 1,2,2,6, Pentamethyl-4-piperidyl sebacate, and more preferably TINUVIN 292 from CIBA.

Also, it is preferable that the amine photostabilizer is about 0.1 to 1 part by weight based on the total weight of the composition. If the amount of the amine photostabilizer is less than 0.1 part by weight, the ability of the composition to absorb ultraviolet rays may be significantly reduced and the composition may be difficult to be protected from ultraviolet rays. If the amine photostabilizer is more than 1 part by weight, The activity of the photoinitiator due to excessive ultraviolet absorption may be inhibited and the curing of the composition by ultraviolet rays may be hindered.

The weight ratio of the ultraviolet absorber to the amine light stabilizer is preferably 1: 1 to 3: 1. If the weight ratio of the ultraviolet absorber to the amine photostabilizer is less than 1, the synergistic effect of the ultraviolet absorber and the amine photostabilizer due to the relative reduction of the ultraviolet absorber may be reduced, If the weight ratio is more than 3, the ultraviolet ray absorption may inhibit the activity of the photoinitiator and the curing of the composition due to ultraviolet rays may be hindered.

The above-mentioned surface-permeable surface strengthening agent can be commercially obtained from EcoCrit (manufactured by Cho Kwang Paint Co., Ltd., eco-company).

Resin pad grinding step

Next, the surface of the reinforced concrete is ground using Resin Pad # 100 to uniformly grind the floor, smooth the surface, and clean the floor without using water.

Application step of ceramic coating agent

Then, in order to maximize the surface strength and durability by penetrating the concrete surface and integrating with the concrete, the ceramic coating agent is uniformly applied to the floor using a heavy layer roller or an airless sprayer.

This is usually carried out with a thin film of 0.3 mm, but it is preferable to control the thickness thereof if necessary.

The ceramic coating agent is preferably a two-part liquid composition consisting of a main part and a curing agent part, and the main part may be mixed with the main part A and the main part B in a volume ratio of 75 to 85:15 to 25.

30 to 40 parts by weight of potassium silicate, 10 to 20 parts by weight of lithium silicate, and 3 to 5 parts by weight of purified water were mixed with 0.5 to 0.6 parts by weight of ammonia, followed by heating for 2 hours 200 rpm / min to prepare a first reaction solution;

10 to 12 parts by weight of 1,6-hexanediol, 1 to 2 parts by weight of purified water and 0.5 to 0.6 parts by weight of oxalic acid were added dropwise to the second reaction solution while stirring at 200 rpm / min for 2 hours while being heated to 120 DEG C Preparing a third reaction solution; And

Cooling the third reaction solution at room temperature and mixing 15 to 17 parts by weight of isopropyl alcohol.

The two-part type ceramic paint is preferably used after mixing the main part and the hardener in a weight ratio of 3.3: 1, homogenizing the mixture for 1 minute or less using a motorized stirrer, and aging the mixture for 5 minutes or less.

Burnishing process

After applying the ceramic coating agent, it is cured for 6 to 12 hours. When necessary, a high-speed heating pad is applied to the concrete floor at a constant pressure to perform a burnishing process. This makes it possible to maximize the strength, hardness and durability of the finished surface and make the finished surface uniform in an integrated state. In particular, burnishing has the effect of enhancing the binding force of a mixture of ceramic powder and magnetic dust filled in micro pores such as cracks and pinholes and promoting hardening.
