Description

581794 ι Description of the 5 'invention (1) [Industrial invention] This method is applied when the protection in a fire is strong. [Known techniques and techniques' are not uneven, and the bone adhesion is sufficient. In addition, building steel coatings are often used in the form of fire coatings. Bone, so scattered than the material. Due to the above application field, it is related to a refractory coating, which is used for foaming to form a heat-insulating layer on a beam made of steel. Steel for coatings, steel for hair and pillars, and fire in a fire In addition, the present invention also relates to the formation of a bubble-type fire and fire coating layer] It is difficult to control the formation of foamed layers due to excessive foaming in refractory coatings Fissures and fragility make the foam layer fire resistant. For construction / steel materials, they are transported to the construction site and coated with mud-like resistance. When the coating spray gun is applied to the finished steel by spraying, the steel used in the predetermined places such as the wall and the wall are mostly foamed by the Η-shaped steel covering the wall, etc., and several types of commercially available products are issued. The foam layer falls off, either because of the foaming or the strength of the foaming layer to the underlying steel itself.

The formation of the fortune-fire coating is performed after the assembly is completed. In order to improve the working efficiency, the refractory coating material or the liquid foaming type refractory method is performed by a spraying method. Foam-type refractory coating is applied. It is necessary to coat the foam-type refractory coating with vinyl sheet or the like in advance. ‘Steel with complex shapes such as square steel pipes.

Description of the invention (2) The loss of refractory coating (1OSS) becomes more and more, so it is considered that there will be an increase in the cost of foaming refractory coatings and foaming refractory coatings. It has problems such as insufficient coating thickness and insufficient fire resistance.

Furthermore, if the refractory coating material used in the past has been considered before being coated on the steel before being assembled, the refractory coating material is mostly an inorganic bonding material such as cement as the main component, and the thickness of the coating is thick. Up to several tens of millimeters, so if it is coated on the steel before it is assembled, there will be a problem that the steel cannot be fixedly joined by the tenon (bo 11). In addition, the refractory coating material is composed of an inorganic bonding material as the main component, and when it is used under a lightweight f bone material or an object containing a large amount of inorganic fibers, its adhesion strength to steel and the compressive strength of the refractory coating material itself will be very weak. On the contrary, if the lightweight aggregate material does not contain the above components, the covering material layer will be very hard, so it will not cause scratches or defects in the covering material layer during transportation and assembly of steel materials. .

In addition, conventionally, antirust primers for foaming refractory coatings have mostly used epoxy MI0 coatings, modified epoxy coatings, alkyd resin coatings or a combination of the above and zinc-rich primer coatings. . In addition, the anti-rust paints specified in the anti-rust paints of JIS include: JIS κ 562 1: General; Erlu paint, m κ 5622: Red lead anti-record paint, jis 5 =.

Hereinafter, each element of the present invention will be described.

When the titanium oxide with a catalytic effect is exposed to fire, the carbonization agent and the synthetic resin are decomposed and dehydrated and condensed to form a carbonized layer to produce a reinforcing effect. Its crystalline forms include anatase type and rutile (rUtUe) type. Among them, anatase type is more effective. By using sharp titanium oxide, it is possible to promote the formation of the foamed layer by its catalyst effect, so as to have better fire resistance than when not used. When two types of rutile-type titanium oxide and anatase-type titanium oxide are used in combination, when compared with the case of using rutile-type titanium oxide alone ', its effect at the time of formation of the foamed layer can be seen.

Hereinafter, each element of the present invention will be described. Foaming refractory coatings are coatings with ①polyvalent alcohols and ③synthetic resins as the main components, of which ②flammability = ammonium phosphate and / or ammonium polyphosphate, and ③the decomposition of synthetic resins begins with warm production It is a field below 25 0 ° C, and when it reaches 300 t, the total solid content will be more than 50% by weight and less than 90% by weight.

The $ polyvalent alcohol is a component that will dehydrate and condense with the flame retardant foaming agent described later, and can hunt the decomposition gas of the flame retardant foaming agent and nitrogen-containing foaming agent to form the foam layer. Polyvalent alcohols include, for example, pentaerythritol, dipentaerythritol, tripentaerythritol, polypentaerythritol, triethylene glycol, sorbitol, m-benzene, phenol, glycerol, trimethylol, trimethylolpropane, diethylene glycol Alcohols, glycerol, and 1,6-hexanediol. In the example shown above, in order to decompose approximately at the same temperature as the flame retardant foaming agent to form a foamed layer, pentaerythritol, dipentaerythritol, tripentaerythritol, and polymer are selected at a decomposition temperature of 260 ° C.

In terms of this ingredient, there are flame retardants such as silicon oxide, inorganic fibers, and asbestos oxide. In the invention of surfactants, film-forming aids, pigments, metal soaps, stabilizers, preservatives, and anti-mildew swords, the invention is based on the price, ④ flame retardant foaming agent, and ⑤ the price The alcohol is selected from any of quaternary ^ and polypentaerythritol and / or poly Ammonium, and Dan ④: ⑤ runners to be explained

581794 5. Description of the invention (20) One of them ① The polyvalent alcohol of the composition can be dehydrated and condensed with the flame retardant foaming agent to be described later, and can be decomposed by the flame retardant foaming agent and nitrogen-containing foaming agent. As an example, the foamed layer 2 may be formed by using at least one of the following materials selected from the following: wound pentaerythritol, pentaerythritol, dipentaerythritol, tripentaerythritol, and polypentaerythritol. The decomposition temperature of the above four substances is about 26 {) t, so the same effect can be achieved no matter which one is used. … 2 of them ② Containing arbitrarily selected foaming agents such as methylamine, guanidine, etc. In the decomposition stage of the foaming control melamine and its derivatives, nitrogen-containing foaming of the polyvalent alcohol If the standard is not sufficient, the foaming performance will be deteriorated. Nitrogen blowing agents can be used, for example, dicyandiamine, azoamine and its derivatives, urea, melamine and hexamethylenedipine. Among the above, from the point of view of increasing the expansion ratio at a temperature different from -④bis «L degree, it is best to use a creature with a decomposition temperature of 37 ° t. When the blending amount of the polyvalent alcohol is 10 (weight), the blending amount of the agent must be 804 to 50 weight parts. If the blending amount of the nitrogen-containing foaming agent is less than 80 parts by weight, the 3 foam layer is used. On the other hand, if the amount exceeds 150 parts by weight, the foamed layer will fall off, and if it is knotted, it will cause resistance to the synthetic tree of 3 ③ components for the purpose of weather resistance. The acrylic resin and alkyd resin are based on synthetic resins at room temperature, such as vinyl resin, vinyl resin, etc. to give adhesion to the coating film, and melamine resin, vinylidene resin, and urinary resin.

The above-mentioned resins may be used alone, or their copolymers may be used, or the above-mentioned resins may be mixed and used. Furthermore, as for the type of the resin, one dissolved in an organic solvent may be used, or one dispersed in water in the form of a latex may be used. When the blending amount of the polyvalent alcohol is 100 parts by weight, if the blending amount of the 'synthetic resin is converted to solid content, it must be 2000 to 500 parts by weight, and more preferably 251 to 400 parts by weight. Within the above range, it is possible to exhibit excellent financial performance. The purpose is to prevent the generated gas from escaping when the synthetic resin layer is softened by heating. Although the deviation from the above range will not affect the foaming height of the foamed layer itself, it will greatly affect the fire resistance of J IS A 1 304. If it is less than 200 parts by weight, there is no way to make up for the foaming gas, so the fire resistance is deteriorated. In addition, if it exceeds 500 'by weight, foaming itself will be hindered, so sufficient fire resistance will not be obtained. Among the 4 ④ flame retardant foaming ingredients, ammonium phosphate and / or polyammonium phosphate must be used. It is also possible to use a substance whose surface has been coated with microcapsules such as melamine.

The flame retardant foaming agent is composed of ammonium phosphate and / or ammonium polyphosphate. Both can be decomposed to about 275 by heating, and it is generated by the endothermic reaction of Ik accompanied by 牯. Reduce material temperature. In addition, a foamed layer having a mesh structure is formed due to the flame retardance effect of the combination with a polyvalent alcohol and a synthetic resin. When the blending amount of the polyvalent alcohol is 1,000 parts by weight, the blending amount of the flame retardant foaming agent must be 280 to 4500 parts by weight. If less than 28 weight parts

2013-3553-FF-ptd Page 25 581794

In this case, sufficient foaming and heat absorption cannot be provided in the lamp, and the fire resistance will be deteriorated. If it exceeds 450 parts by weight, the foam layer will be cracked due to excessive foaming, and the fire resistance will be deteriorated. No. 5 ⑤ The second component ^ Titanium is added to the above-mentioned ①, ③: ④ by the catalyst during heating to form a foam layer in a lower temperature. When the amount of the polyvalent alcohol is 100 parts by weight, the amount of the two f must be 100 to 300 parts by weight. The catalyst effect will be inadequate if the weight is less than 100 weight. If it is used for general concealment purposes =

with. In addition, the decomposition temperature of titanium dioxide exceeds ·. c. Therefore, if the weight of the foamed layer is not large, the residual amount of the foamed layer is too high: the foamed layer becomes very fragile. In view of this, finally, the foamed layer is blown off due to the force during heating, so the fire resistance cannot be obtained. In JP 7-2 31124, "Although there is titanium dioxide compared with polyvalent alcohols in the above range? Conventional examples of use", melamine is not used in this case. Titanium dioxide can use either the anatase type or the rutile type. The J type is more effective. The conditions above] to 5 must be sharp = 0 to 6

In addition, since the drying of the coating film takes time, the manufacturing efficiency is reduced. The fire performance of the foaming fire coating layer was measured by the following method. That is, a 2 mm thick foaming type fire-resistant coating is applied to a square steel tube (300 mm on one side and 9 mm in thickness of a member) of STKR400 square general structure with a length of 1 meter in accordance with JIS G3466. It was hardened and dried to form a foamed refractory coating layer, and it was made into a test object.

b) Steel materials coated with foamed refractory coatings. J. Measurement of material loss, 'Impact resistance test and heating test, etc.' Hair and foam coatings were used as examples. The main formulation ratio of the foaming type = coating is: 100 parts by weight of synthetic resin as a solid part, 100 parts by weight of ammonium polyphosphate, 100 parts by weight of pentaerythritol, 100 parts by weight of polycyanide, oxidation 100 parts by weight of titanium, 100 parts by weight of solvent L, and a synthetic resin latex were used for the bonding material. In Comparative Example 4, rock wool was used, and in Comparative Example B, light mud (mortar) was used. Cement is used as the bonding material for f cotton and light mud. As for the coating method ', spray coating is performed using a spray gun.

A measurement of material loss is performed on 7.5 pieces of 200 mm in width, 400 mm in length, 13 mm in thickness, 8 mm in thickness and 10,000 mm in length. 100 kg of refractory coating materials of Examples, Comparative Examples A, and Comparative Examples B were coated in such a manner that they were uniformly coated on 5 pieces of 11-shaped steel—f ′ sub-calculated material loss. The coating amount of the reed-shaped steel was determined from the difference between the weight of the reed-shaped steel to be coated and the weight of the η-shaped steel after coating.

581794

5. Description of the invention (51) In the foaming refractory coating of the embodiment, the coating amount is 94 kg with respect to the amount of 100 kg. That is, the loss of material is 6 kg. On the other hand, in the asbestos of Comparative Example A, the material loss was 53 kg when the coating amount was 0 kg. In the light mud of Comparative Example B, the coating amount was i W kg, and the material loss was 44 kg. Since the foamed refractory coating of the embodiment can be recycled, the scattered foamed refractory coating can be recycled, and the recycled foamed refractory coating can be reused, so the material loss is compared with ^ comparative examples ^ and comparative examples B is much less. Since Comparative Example A and Comparative Example B use cement at the joint material, there is a limitation on the usable time of the material, and 2 the scattered material cannot be recovered and reused. ^ Second, an impact resistance test was performed. The impact resistance test is to apply various refractory coating materials of Examples, Comparative Examples 1 and 2 to an SS400 steel plate having a length of 30 (} mm, a width of 300 mm, and a thickness of 9 mm, and left to stand "= to be a test" The coating thickness of the individual refractory coating materials is the thickness specified in J IS A1 304 for one hour. The thickness is 2.5 mm in the foamed refractory coating of the actual example (after drying). In comparison with ^:] A, it is 30 mm in asbestos, and in the light mud of Comparative Example β, it is exactly the same. Two pieces of each of the above-mentioned test objects are used for the impact resistance test and Adding and dropping the impact resistance test is the result of placing the test object with the test surface facing upwards on the water and placing the iron ball with a weight of 5 kg flat from a height of 1 meter above the surface of the test object. The foamed refractory coating with peeling or defect is not applied at all. For those using Comparative Example A and Comparative Example B, it is 581794. 5. Description of the invention (52) Part of the coating layer is peeled off and the surface is generated. Impact traces. As can be seen from the examples, by using a synthetic tree Fat latex can provide good adhesion between the coating layer and the steel sheet, and is rich in softness. In Comparative Example A and Comparative Example B, cement was used, so although the adhesion between the coating material layer and the steel sheet is still good. Quite good, but the coating material layer has no softness ^^ From now on, the test object that has completed the impact resistance test and the test object that has not been subjected to the impact resistance test are performed according to the standard heating curve specified in J IS A1 304 Heating test. Install a thermocouple in the test object in advance, measure the inner temperature, and use the time to reach 500 ° C as the fire resistance time. &Amp; The test object without impact resistance test in the example is 6 丨 min. The test object that completed the impact resistance test was 62 points. In Comparative Example a, the test object without the impact resistance test was 84 points, and the test object after the impact resistance test was 46 points. In addition, In Comparative Example b, the test object without the impact resistance test was 90 points, and the test object after the impact resistance test was 52 points.

= The above results show that, among the test specimens which have not been subjected to the impact resistance test, the fire resistance of each of the test specimens of the examples, Comparative Example A, and Comparative Example β is 60 or more, and they have sufficient heat resistance. It is also apparent from the examples that the test object after the impact resistance test also has sufficient fire resistance. However, in the test object after the impact resistance test, the coating on the surface of the test object was partially peeled off, so that it was found that the fire resistance was also reduced. c) Forming method of refractory coating
