Floor coating construction method

The invention relates to a floor coating construction method, in particular to a floor coating construction method using epoxy resin.

Nowadays, in various buildings such as homes, office buildings, public places, etc., it is generally common to lay floor tiles or stone on the concrete floor to make the ground more beautiful, and the use of floor tiles or stone has the characteristics of smooth surface, and can make the ground It is easier to clean the action. In addition, it can avoid the skin from damaging the rough surface of the human body and reduce the risk of injury. However, the floor tile or stone can effectively improve the appearance and cleanliness of the ground, but its cost. It is quite expensive and the inconvenience caused by the construction time.

Therefore, some manufacturers have developed a floor coating method to replace the existing floor tile or stone laying method, which is mainly applied with a primer on the cement floor, and then coated with a layer of mixed quartz sand on the primer. And leveling, and after the middle coating is dried, the last layer of the smooth surface coating is applied thereon, thereby generating a cheap floor coating construction method, and the rough cement floor can be covered. And through the uppermost smooth surface coating to achieve more aesthetics and prevent people from directly contacting the rough ground, the main use can be dust-free or dust-free, crack-resistant, easy to clear and easy to complete. This kind of floor coating construction method is widely used in various buildings such as precision semiconductors, clean rooms of precision electronics, operating rooms, dust-free spaces in computer rooms, electronics factories, chemical plants, machinery factories, etc. The ground can be more beautiful and easy to organize, and even more materials such as epoxy resin can be used for construction. The coating coated with epoxy resin and quartz sand can make the mask resistant to moisture, heavy pressure and impact. Characteristics, At present, such a construction method still has its problems. After a period of use, the epoxy resin structure is broken due to the accumulation of moisture, and the ground is cracked, so that it cannot meet the requirements of precision semiconductors. The need for a high-precision electronic clean room has a high demand for the ground. Therefore, how to improve this construction method is an important issue at present.

In view of the above problems, the present invention provides a floor coating construction method, the steps comprising: (a) coating an undercoat layer on a substrate, the undercoat layer being capable of sufficiently penetrating the substrate; (b) Applying an adhesive layer on the substrate; (c) applying a mortar layer on the adhesive layer, the mortar layer material is mixed with epoxy resin and quartz sand; (d) after the mortar layer is hardened, applying on the mortar layer a sealing layer, the sealing layer material is mixed with epoxy resin and gypsum powder; (e) applying a flow-forming mortar layer on the sealing layer; and (f) after the mortar layer is to be hardened, in a flow exhibition A top coat is applied to the mortar layer.

One of the objects of the present invention is that the mortar layer material is mixed with epoxy resin and quartz sand, and the ratio of the epoxy resin to the quartz sand is 1:10 to 1:20, and the amount of fine sand of the quartz sand is coarse and coarse. The ratio of sand amount is 1:4~1:5.

A further object of the present invention is that the sealing layer material is mixed with epoxy resin and gypsum powder, and the ratio of the epoxy resin to the gypsum powder is 1:4.

The mortar layer and the sealing layer coated by the above epoxy resin mixed with quartz sand, epoxy resin and gypsum powder, and then the ground is not used for a period of time to damage the epoxy resin structure due to accumulation of moisture. The ground cracks, and can effectively improve the land, increase its service life, durability and resistance to stress, in order to better meet the market demand.

For a more complete and clear disclosure of the technical means, the object of the invention and the successful performance of the present invention, the following is accompanied by the accompanying drawings, which are described in detail below.

Please refer to the first figure and the second figure. The first figure is a flow chart of the floor coating construction method of the present invention, and the second figure is the floor coating made by the floor coating construction method of the invention. In a perspective view, step 101 is to apply an undercoat layer 22 on the substrate 21. The purpose of the undercoat layer 22 is that the undercoat layer 22 can sufficiently penetrate the substrate 21 and completely wet the substrate 21, while the undercoat layer 22 material It is an epoxy resin; after the primer layer 22 is applied, it is allowed to stand for a period of time, preferably 30 minutes, and then the subsequent layer 23 is applied on the substrate 21, that is, step 102, and then the layer 23 material is The epoxy resin is stirred by the epoxy resin and directly coated on the substrate 21 without adding any sand material; in step 103, a mortar layer 24 is applied on the adhesive layer 23, and the mortar layer 24 is made of epoxy resin and Quartz sand is mixed, and the ratio of epoxy resin to quartz sand is 1:10~1:20. The proportion of mixing is determined by the construction ground, and the ratio of fine sand to coarse sand is 1:4. ~1:5, the best is 1:5, the use of fine sand is intended to fill the gap of the coarse sand, so that the mortar layer 24 is more compact without gaps, After the material is thoroughly mixed, the floor is leveled by the pulverizer, that is, the material is flattened, the epoxy resin and the quartz sand will be more compact, and the ground is also more flat; after the mortar layer 24 is hardened, the hardening time Preferably, the sealing layer 25 is applied to the mortar layer 24 (step 104). The material of the sealing layer 25 is mixed with epoxy resin and gypsum powder, and the ratio is preferably 1: 4, and the sealing layer 25 is flattened on the mortar layer 24 with a trowel; in step 105, the flow-creating mortar layer 26 is applied on the sealing layer 25, and the material of the flowing mortar layer 26 is epoxy resin. Before the application of the flow-creating mortar layer 26, it is necessary to wait for 1 day to harden the sealing layer 25, and the flow-creating mortar layer 26 is mainly for roughening the surface of the sealing layer 25 with epoxy resin. The surface is flattened, so that the surface coating layer 27 is less likely to have bubbles, and the finished surface can be relatively flat; in step 106, after the mortar layer 26 is hardened, it is applied to the flow-creating mortar layer 26. The top coat layer 27, the material of the top coat layer 27 is epoxy resin, and a light grinder is applied before applying the top coat layer 27, and the ground is ground with a suitable grinding piece. After that, the AB glue can be used to level the unevenness of the flatness to ensure the flatness of the smoothing mortar layer 26, and the top coating 27 is applied with a file. It is necessary to keep the finished surface as flat as possible. .

In summary, in the embodiment of the present invention, the mortar layer and the sealing layer coated by the epoxy resin mixed with the quartz sand, the epoxy resin and the gypsum powder can more effectively block the moisture and make the ground use a section. After the time, the epoxy resin structure will not be damaged due to the accumulation of moisture, which will cause the ground to crack and increase its service life to better meet the market demand.
