Description

A method for attaching decorative stainless steel sheet on granite surface

technical field

The invention relates to the field of decoration and decoration, more precisely, it relates to a method for attaching decorative stainless steel sheets on the surface of granite.

Background technique

The unique physical properties of granite and its beautiful patterns make it a good material for construction, and it is known as the "king of rocks". Many places or objects that need to be weather-resistant or long-lasting are made of granite. Granite has uniform structure, hard texture and beautiful color. It is a high-quality building stone. The compressive strength varies according to the stone variety and origin, and is about 1000-3000 kg/cm. Granite is not easy to weather, beautiful in color, and its appearance and color can be maintained for more than a hundred years. Due to its high hardness and wear resistance, it is not only used for high-level architectural decoration projects and hall floors, but also the first choice for outdoor carvings.

Various stones made of granite are widely used in architectural decoration, and stainless steel sheet for decoration is also a commonly used surface decoration material. In the process of daily engineering construction or decoration, stainless steel sheets need to be fixed on the granite surface in many occasions. Fixing with steel nails will affect the appearance and the process is complicated, while sticking with ordinary glue will easily warp and fall off the stainless steel sheet.

Contents of the invention

The invention mainly solves the technical problems existing in the prior art, thereby providing a method for attaching a decorative stainless steel sheet on the granite surface.

Above-mentioned technical problem of the present invention is mainly solved by following technical scheme:

A method for attaching a decorative stainless steel sheet on a granite surface, comprising the following steps:

①Use a spray device to evenly spray the sodium hydroxide solution with a concentration of 60-68% on the surface of the granite, and then spray it again after 2-3 hours. After 2-3 hours, rinse the surface of the granite with clean water and dry it naturally;

②Use JL-498 quick-drying glue to form criss-cross adhesive strips on the back of the stainless steel sheet. The width of the adhesive strips is controlled at 2-4mm, and the spacing of the adhesive strips is controlled at 3-15cm. Sprinkle fine steel grit evenly, the particle size of fine steel grit is 0.3-0.6mm, shake off the excess steel grit after 3-5 minutes, and the steel grit and stainless steel sheet on the adhesive strip are firmly pasted;

③ Take 5-7 parts of white latex, 4-5 parts of putty powder, and 5-7 parts of water by weight, mix them evenly to make an adhesive, and apply the adhesive evenly on the surface of the granite, and then apply the step ②The finished stainless steel sheets are pasted on the granite in turn and compacted, and then it can be cured.

As a preferred embodiment of the present invention, in step ①, the sodium hydroxide solution is sprayed with a heating spray device, and the temperature of the sodium hydroxide solution is controlled at 60-70°C.

As a preferred embodiment of the present invention, in step ③, take 6 parts by weight of white latex, 4 parts of putty powder, and 5 parts of water, and mix them uniformly to make an adhesive.

The method of the present invention first corrodes the surface of the granite with a strong alkali solution to make the surface of the granite easier to bond, and the back of the stainless steel sheet uses quick-drying glue to fix the fine steel sand, so that the stainless steel The bonding between the chip and the granite is firm and durable, and the materials used in this method are all common materials, and the construction cost is also relatively low.

detailed description

The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[Example 1]

A stainless steel sheet for decoration is pasted on a granite wall with an area of 25.7 square meters indoors, and the specification of the stainless steel sheet is 40×40cm.

①Use a spray device to evenly spray 60% sodium hydroxide solution on the surface of the granite, and then spray it again after 3 hours. After 3 hours, rinse the surface of the granite with clean water and dry it naturally;

②Use JL-498 quick-drying glue to form criss-cross adhesive strips on the back of the stainless steel sheet. The width of the adhesive strips is controlled at 2mm, and the distance between the adhesive strips is controlled at 5cm. Steel grit, the particle size of fine steel grit is 0.3mm, shake off the excess steel grit after 5 minutes, and the steel grit and stainless steel sheet on the adhesive strip are firmly pasted;

③ Take 5 parts of white latex, 4 parts of putty powder, and 5 parts of water by weight, mix them evenly to make an adhesive, apply the adhesive evenly on the surface of the granite, and then make the finished stainless steel in step ② The sheets are pasted on the granite in turn and compacted, and then it can be cured.

24 months later, the company's technical personnel conducted a technical return visit to the project, and the stainless steel sheet was closely attached to the granite wall, and the corners of the stainless steel plate did not turn up or fall off in the entire wall.

[Example 2]

Paste decorative stainless steel sheets on a granite wall with an area of 56.8 square meters. The size of the stainless steel sheets is 60×60cm.

①Use a spray device to evenly spray 68% sodium hydroxide solution on the granite surface, and then spray it again after 2 hours. After 2 hours, rinse the granite surface with clean water and let it dry naturally;

② Use JL-498 quick-drying glue to form criss-cross adhesive strips on the back of the stainless steel sheet. The width of the adhesive strips is controlled at 4mm, and the spacing between the adhesive strips is controlled at 8cm. Steel grit, the particle size of fine steel grit is 0.6mm, shake off the excess steel grit after 5 minutes, and the steel grit and stainless steel sheet on the adhesive strip are firmly pasted;

③ Take 7 parts of white latex, 5 parts of putty powder, and 7 parts of water in parts by weight, mix them evenly to make an adhesive, apply the adhesive evenly on the surface of the granite, and then make the finished stainless steel in step ② The sheets are pasted on the granite in turn and compacted, and then it can be cured.

24 months later, the company's technical personnel conducted a technical return visit to the project, and the stainless steel sheet was closely attached to the granite wall, and the corners of the stainless steel plate did not turn up or fall off in the entire wall.

The above is only a specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto, and any changes or replacements that do not come to mind through creative work shall be covered within the scope of protection of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope defined in the claims.
