Description

Method for manufacturing non-combustible flooring using ceramic binder {Method for manufacturing non-combustible flooring using ceramic binder}

The present invention relates to a method for manufacturing a non-combustible flooring using a ceramic binder.

A binder refers to a material that binds materials of different materials and gives required properties such as adhesion, film properties, or chemical resistance in an end use. Binders can be largely divided into organic binders and inorganic binders. Organic binders form a material bond through a carbon bond or ether bond, and inorganic binders combine materials through a Si-O bond or an Al-O bond. Binders can be used for the manufacture of various materials such as paints, waterproofing agents, fibers or rubber. On the other hand, ceramic is an inorganic non-metal hardened by firing, and means a non-metal solid mainly combined with oxygen.

A problem with organic binders widely used in various industrial fields is that they can generate volatile organic compounds (VOCs). Since volatile organic compounds can have a serious impact on the environment, regulations on them are gradually being strengthened. As an alternative to such an organic binder, an aqueous binder or an inorganic binder has been proposed.

Prior art related to the manufacturing method of the inorganic binder includes Patent Publication No. 2001 - 0027894 "Silica Binder and Manufacturing Method Thereof". The prior art relates to a silica (SiO ₂ )-based coating material with excellent adhesion capable of forming a thin film by being coated on a surface of glass, single-crystal silicon, or metal, and a manufacturing method thereof, wherein Si(OC ₂ H ₅ ) ₄ or ethyl silicate is used. Silica sol and polysiloxane made by hydrolysis in an aqueous acid solution or R ₂ Si(OR') ₂ (R is CH ₃ and R' is any one selected from H, CH ₃ and CH ₂ CH ₃ ) Disclosed is a silica sol binder having a Si-CH ₃ group prepared by reacting and having low viscosity and excellent adhesive strength. Another prior art related to the manufacturing method of an inorganic binder is Patent Registration No. 0758286 entitled “Method for Manufacturing Inorganic Polymer Binder”. The prior art has 27 to 30 repeating units (n) of monosiloxane based on -Si-O- bonding units and disiloxane based on -Si-O-Si- bonding units ( An inorganic binder having 15 to 18 repeating units of disiloxane) is disclosed.

In general, in the field of materials requiring heat resistance, such as kitchen utensils and cooking utensils, a method of preparing a coating agent by reacting silica sol with silane using a sol-gel reaction is widely used.

As such a method, two methods have been conventionally proposed.

1). There is a method of forming a coating agent by mixing and stirring silica sol, silane, alcohol, base catalyst or acid catalyst (hereinafter referred to as 'Conventional Method 1').

2). Part of the catalyst is added to silica sol to make 1 liquid, silane is used as 2 liquid, the two are first mixed and stirred to react, aged for a certain time, alcohol is added as 3 liquid, stirred again, and aged to obtain a coating agent There is a method for making (hereinafter referred to as 'conventional method 2').

And in the case of producing a colored coating agent, the coating agent is prepared by adding a pigment in the last step.

However, in the case of conventional method 1, after 48 hours at room temperature, the coating agent is gelated by a condensation reaction and cannot be operated anymore, so it is difficult to store the coating agent for a long time or transport it over a long distance. .

In addition, in the case of the conventional method 2, since the catalyst is added to the silica sol, it is difficult to preserve the liquid for a long time, and the working time, which is the use time after forming the coating agent, does not exceed 48 hours. Therefore, it has been a major obstacle in overseas exports that require long-term storage and transportation.

On the other hand, both of the coating agents prepared by conventional methods 1 and 2 require preheating of the material before coating the coating agent, and there is also a problem that a high temperature drying process of 200 ° C. or more is required during the painting process.

To this end, a method for manufacturing an inorganic non-combustible ceramic binder capable of long-term preservation, which is a coating composition that extends the working time of the coating agent and overcomes the limitations of working conditions such as preheating and high-temperature drying, is disclosed in Korean Patent Publication No. 10-2019-0005924 As a result, 25 to 35% by weight of isopropyl alcohol (IPA) was added to 35 to 38% by weight of methoxysilane, and 1.5 to 5% by weight of tetraethoxysilane (TEOS) was gradually stirred while first stirring for 5 to 10 minutes. A 1-1 step of preparing a 1-1 liquid while dispersing by inputting;

Step 1-2 of preparing liquid 1-2 by adding 1.5 to 2.5% by weight of acid catalyst dropwise to liquid 1-1 and stirring for 20 to 30 minutes;

A second step of preparing a second liquid by mixing and stirring 8 to 15% by weight of distilled water with 10 to 15% by weight of colloidal silica (silica sol);

The 2 liquids are repeatedly dropped into the 1-2 liquids little by little, but when they turn white at the time of initial drop, they are stirred until they become transparent, and when they become transparent, some of the 2 liquids are dropped again until they also become transparent, a total of 20 ~ A third step of reacting for 30 minutes;

Next, it is an inorganic nonflammable ceramic binder manufacturing method in which a fourth step of improving adhesion by gradually adding 0.5 to 1.5% by weight of epoxysilane is performed. However, this has the effect of extending the storage period, but the addition of isopropyl alcohol is small, so the dispersibility is low, and the stirring time is increased, which takes a lot of manufacturing time. Since it has low dispersibility, it is difficult to maintain a certain thickness, so there is a problem in using it as a flooring agent.

The present invention is to solve this problem, and an object of the present invention is to stir methoxysilane and isopropyl alcohol in a 1: 1 ratio to increase the dilution of methoxysilane and improve the dispersibility, thereby increasing the viscosity to add incombustible inorganic materials and disperse mixing It is intended to provide a method for manufacturing a non-combustible flooring using a ceramic binder that facilitates.

It is to provide a non-combustible flooring manufacturing method using a ceramic binder that enables accurate stirring even for beginners by dividing and stirring each time it changes to obtain an agitated substance C of constant viscosity.

Another object of the present invention is that the ceramic binder used in the present invention dilutes the silane and stirs the acetic acid to the agitated material A, and the colloidal silica diluted agitated material B is stirred so that the stirred material C is heated to form a dispersant that is additionally added It is intended to provide a method for manufacturing a non-combustible floor covering using a ceramic binder that maintains a storage period of 6 months to 1 year by providing a ceramic binder of the agitated material D that is well melted and maintains dispersibility.

Another object of the present invention is to improve the dispersibility of the stirring material D, which is the ceramic binder used in the present invention, to the stirring material D, 10) kaolin, 11) titanium dioxide, 12) calcium carbonate, 13) talc, 14) chromium oxide Provides a non-combustible flooring manufacturing method using a manufacturing ceramic binder that maintains storability by mixing and aging to have adhesiveness even when inorganic powder is added, and provides a non-combustible adhesive E having non-combustibility because a certain thickness is provided by the inorganic powder is to do

This is considering that the surface vibration and the time to change to transparent usually are 3 to 5 minutes.

The process of checking transparency is the interval 1 (9-4) and interval 2 (9-5) of the border band (9-2) and the island line (9-3) of the confirmation plate (9) photographed by the camera (8) for each period. The control unit 3 recognizes, but the high level is the border band 9-2 and the island line 9-3 so that the control unit 3 can recognize, and the low level is the interval 1 (9-4) and the distance 2 (9-5) is followed to determine whether it is transparent by recognizing 110110011 where the low level and the low level are repeated, but if the low level interval is 80 to 90% of the normal value interval, it is determined as transparent. This is actually transparent due to surface wave vibration during rotation, but in order to prevent it from being recognized as opaque, it is judged as 80 to 90%, and if it is less than that, it is opaque, and if it is less than that, it is recognized by the control unit as transparent. When the controller 3 recognizes it as transparent, it notifies to output it to the display 4 (step 1 (S1)). Usually, this case coincides with the time when the temperature rises from room temperature to 30° C. as shown in FIG. 3 .

2) Following step 1 (S1), a portion of the remaining stirring material B (80 parts by weight) is dropped again, bubbles are generated by hydrolysis, an exothermic reaction occurs, and after 3-5 minutes of stirring, the reaction is completed in opaque according to the reaction It becomes transparent and the process of determining whether or not the transparency is within 80 to 90% of the normal transparency interval by the control unit 3 as shown in FIG. 2 (S2) is repeated several times [until the process 4 (S3, S4) when the agitating material B is exhausted], the stirring condition is 250 ~ 350 rpm, the stirring time increases when it is less than 250 rpm, and the viscosity increases due to gelation when it exceeds 350 rpm it gets too high In process 1 (S1), if the initial heat generation temperature (starting from room temperature 20 ℃) is 30 ℃, process 2 (S2) is 40 ℃, process 3 (S3) is 50 ℃, process 4 (S4) transparency is 80 ~ When it reaches 90%, it is considered that the temperature rises to 60 ° C., but priority is given to transparency over the set temperature, and the present invention functions to accurately determine the transparent time point without error.

3) When the transparency of the stirred substance reaches 80 to 90% in the stirrer, it is further stirred until it reaches 80° C. to obtain the stirred substance C in a sol state [step (S5)]. Specifically, when the transparency reaches 80 to 90% and the temperature reaches 60° C. after adding the last remaining agitated substance B, only stirring is further performed and when the temperature reaches 80° C., the stirring is terminated. In the present invention, accurate and rapid stirring is possible by determining based on temperature and transparency and performing stirring by quickly determining transparency.

Subsequently, 7) 7-15 parts by weight of hydroxypropyl cellulose powder (thickener) is gradually added to the stirred material C, the viscosity is increased by adding a thickener, and 8) butoxyethanol Adding 10-12 parts by weight, delaying drying of stirred material C, dissolving the thickener (HPC) well to induce uniform dispersion, 9) Glycidoxy propyl trimethoxy silane (XIAMETER ™ OFS-6040 silane) It maintains the dispersed state by adding 3 to 7 parts by weight.

When stirred for 2 to 6 hours in a sealed state, an exothermic reaction occurs, and when stirred for 2 to 6 hours secondly, it is aged (stopping heat, the temperature is cooled to room temperature) to obtain a ceramic binder, Stirred Material D.

In the above process (S5), since the agitated substance B is viscous, if the amount of addition to the agitated substance A is unintentionally divided and added to the agitated substance A as shown in Table 1 below, the temperature at the time of judging that the agitated substance B is measured is 1 /n It functions to manufacture precise and uniform agitated substance C by double-checking the transparency and temperature rise temperature to contribute to the improvement of the precision of the added amount by measuring whether the amount exceeds or is insufficient by temperature change.

Agitation A Agitation B
Dividing amount = (stirring material B) 1/n
(n is the number of additions by dividing. Example when n = 4, not equally divided) temperature change transparency 650 to 800 parts by weight 80 parts by weight 20℃ to 30℃ ○ 85 parts by weight (amount in excess) 30℃ to 42℃ ○ 75 parts by weight (shortage) From 42℃ to 51℃ ○ 80 parts by weight From 51℃ to 61℃ ○ Stirring up to 80℃

II. Non-combustible flooring manufacturing process by mixing inorganic powder (Homo Mixer)

Put the agitated material D into the homomixer at 800-900 rpm and rotate the mixer rotor while

Put the stirring substance D in a homomixer, 10) 200-250 parts by weight of kaolin, 11) 60-100 parts by weight of titanium dioxide, 12) 50-55 parts by weight of calcium carbonate, 13) 50-55 parts by weight of talc, 14) chromium oxide 260-360 parts by weight of inorganic powder are sequentially added and mixed at 400-500 rpm for the first 50-70 minutes at medium speed to increase the adhesion between the stirring substance D and kaolin, and then at 600-700 rpm for 2-4 hours in the second step. High-speed mixing increases the viscosity of kaolin, titanium dioxide, and calcium carbonate while improving the dispersibility of chromium oxide, followed by sequentially performing low-speed mixing in three stages at 100 to 150 rpm for 30 to 60 minutes so that talc and ceramic binder An inorganic powder mixing process, which is a non-combustible flooring material manufacturing process for preparing a non-combustible flooring material E that maintains storability, is non-combustible, and has a certain thickness (350 to 400 μm) when applied, is performed.

3) Add 30 g of tetraethoxysilane ([OFS-6697] (manufactured by Dow Silicon Corporation)) and stir for 10 to 15 minutes,

4) 20 g of acetic acid was added dropwise to obtain 710 g of stirred material A.

Agitated material B manufacturing process in another agitator 2

5) 260g of colloidal silica (Cataloid SN, Ilhui Catalytic Chemicals Co., Ltd., Japan)

6) 60 g of water (H2O) was stirred and mixed to obtain 320 g of stirred material B.

Agitation C manufacturing process

Divide the stirring material B (320g) evenly (1/4) and slowly drop and stir 80g of the stirring material B to the stirring material A (710g), and the stirring condition is to recognize the confirmation plate (9) through the camera at the time when the stirring condition becomes transparent from opaque judged and added. The process of adding may exemplify the state of FIG. 3 .

1) 80g of a portion (1/4) of the stirred material B is dropped into the stirrer 1 of the stirred material A, and when stirred in the stirrer 1, the colloidal silica forming the stirred material B and the alkoxysilane (methyltrimethoxysilane, Tetraethoxysilane) generates bubbles in the hydrolysis reaction and starts to exotherm, changing to an opaque state. Agitation is 3-5 minutes, and the time when the temperature starts to heat up at room temperature (20 ℃) and becomes transparent coincides with the time when the temperature rises by 10 ℃, and the camera 8 shown in FIG. The confirmation plate 9 is photographed as shown in FIG. 5, and the photographed photograph is recognized through the input terminal I1 of the control unit 3 through the input/output interface 10 in the memory shown in FIG. 4, and the recognized picture has the desired transparency. In order to determine recognition, as shown in FIG. 5, the dark border band (9-2) and island line (9-3) in the photo are at a high level, and the interval 1 (9-4) and interval 2 (9-3) of light color 5) is recognized as a low level, and it is difficult to identify the confirmation plate 9 when the transparency is low as shown in (a) as shown in FIG. When it becomes slightly clear as in (c) and reaches 80 to 90% of the normal interval as in (d), the control unit 3 displays the binary number 110110011 (in FIG. 7 (d), if the low-level interval is small, "0" , when the interval is wide, it is defined as "00", and similarly, when the interval is wide, the high level is recognized as a normal transparency value of 11). When the control unit 3 recognizes it as transparent, the control unit 3 stops the output to the output terminal O1, and at this time, it is T1 time in FIG. 3 when the stirred material is 30 ° C ( process 1),

2) The controller 3 stops the output to the output terminal O1, opens the valve V1 (opens it by applying a level signal under valve operation), drops 80 g of the agitated substance B again, and returns to the camera When the transparent state reaches 80 to 90% of the normal interval as shown in FIG. 7 (d) through the photograph of the confirmation plate (9) through (8), the control unit 3 is shown in FIG.

It is repeated (up to process 4 when the stirring material B is exhausted), and the stirring condition is 250 to 350 rpm. If the stirring time is less than 250 rpm, the stirring time increases, and if it exceeds 350 rpm, the viscosity becomes too high due to gelation.

14) Mix 300g of chromium oxide (an inorganic pigment that functions as a non-combustible colorant) in turn to maintain a uniformly dispersed state of inorganic particles in the ceramic binder. Increase the adhesion between water D and kaolin, and then mix at 600 to 700 rpm in two stages at high speed for 2 to 4 hours to increase the viscosity of kaolin, titanium dioxide, and calcium carbonate while improving the dispersibility of chromium oxide, followed by 30 minutes The low-speed mixing process in three stages at 100-150 rpm for ~60 minutes is sequentially performed to maintain the storability of talc and ceramic binder, and to the stirring substance D, 10) kaolin, 11) titanium dioxide, 12) calcium carbonate, 13) talc , 14) Inorganic powder of chromium oxide was added, but aged to have adhesiveness to maintain storability and to prepare a non-combustible floor agent E having incombustibility, which was coated on the floor.
