Description

Manufacturing method of fire resistant insulation plastering material

Figure is a drying and mixing process diagram of the present invention.

The present invention relates to a method for producing a thermally insulating powder mortar that combines an appropriate amount of water with a powdery material, such as plaster mortar, to the walls and ceiling surfaces during the construction work.

Conventional mortars have not been developed with thermal insulation in the building plastering process, but there have been fireproof castables in the industrial shaft field, but these are expensive because they have been calcined and finely divided into feldspar, etc. Could not be introduced.

As a current process, it is applied as a separate cement board after plastering as a general cement mortar. It is a plate-shaped insulator that is mixed with plaster and talc, and pressure-molded. The process is delayed, deformed and detached when the construction period is over, and the connection seam is curved, which is not good for aesthetics.

The present invention omits the double workability of insulation and plastering, which is a method of forming plate material, and as a plastering mortar, as a powdery material mixed with a heat insulating material to cement, which is a basic element of plastering, in order to finish plastering and insulation by simultaneous construction. When only kneading with water, it is attached like ordinary cement mortar, which causes the effect of plastering and simultaneous thermal insulation. In general, in order to solve the fastness of calcined gypsum, which is impossible, there is a gist of the drying and material mixing ratio. The purpose was to remove the defects such as the effect of heat insulation, price problems, and construction problems in the conventional heat insulators, and to mass-produce them at low production prices. After making it into small particles, it has high adhesion and insulation, and finely grinds the surface of gypsum, diatomaceous earth, talc, etc. It was dried at the same temperature and mixed at the same time. This predicted the moisture of the gypsum and its condensation during penetration, and it was mixed with other materials in the fine state to maintain the required solidification time as mortar. The rapid solidification resolves the obstacles that cannot be generally used as mortar.

The insulating and surface lubricants were kneaded with adhesive C. M. C and cement of the plaster mortar material at a second temperature under a certain temperature to obtain a powder insulation plaster.

The fire-resistant insulating plastering material obtained through the manufacturing process of the present invention is light in weight and its thermal conductivity (test according to KSL 3306-80) is 0.184 kal / mh ° C. , Condensation removal, moisture proof, soundproofing effect is added, and only water is to be combined with general cement mortar.

Hereinafter, the gist of the present invention will be described by process according to the accompanying drawings.

[Step 1]

Asbestos, rock wool, and glass wool, which have good bonding properties, are placed in special cutters of RP M 1,000-1,200, respectively, and asbestos is cut to 3 to 3.5 mm, rock wool to 2-3 mm and glass to 1-1.5 mm. Asbestos 10%, rock wool 4%, glass wool 6% by weight is appropriately blended.

[Step 2]

In the grinder, gypsum is divided into 250-300 mesh, diatomaceous earth is 350-400 mesh, and talc is 200-250 mesh. 22%, diatomaceous earth 3%, talc 2% by weight is suitably blended.

[Step 3]

The compound (A) of the first step and the compound (B) of the second step are separately introduced into the hopper of the first mixer as in the embodiment of the drawing, and then mixed with drying at the temperature of 50 ° C. to 60 ° C. for 25-30 minutes. I send it to you.

[Step 4]

C. It is a fiber detergent adhesive when the dry-pressurized mixture in the third process is put into the secondary remixer. In order to give MC and cement with adhesive strength and strength, 3% by weight of CM C and 50% of cement are added to the hopper at the same time. Obtain an insulating plaster.

In the above process, by reducing the compounding ratio of the material, the effect of thermal insulation and the rate of solidification can be properly adjusted, so that the varieties can be subdivided according to the place of use and the season (that is, if the content of gypsum is high, it is suitable for winter construction.

In this way, the thermal insulation plastering material obtained in this manufacturing process can be used immediately by mixing water as a powder state without constructing a separate plate insulation material, and when applied for plastering on the cement wall surface, the surface is formed finely and the thermal insulation effect is excellent. Prevention, as well as moisture-proof, soundproofing effect is good, and the construction is easy to provide a low-cost thermal insulation plastering material.
