Embodiment

[0007] Example: Manufacture a plastic-steel environmentally friendly composite ceiling with 600×600 (mm) as the unit of measurement, weigh 2800g gypsum powder, 120g cement, 60g glass fiber, 750g perlite and 35g thermosetting powder coating, and prepare them. 1750ml of aqueous solution of polyvinyl alcohol and citric acid. The specific manufacturing steps are as follows:

[0008] 1. Lay the mold flat on the flat marble;

[0009] 2. Pour the weighed gypsum powder into the bowl with the solution;

[0010] 3. Start stirring for 2-3 minutes;

[0011] 4. Pour the weighed fiber and perlite into a mixing bowl and mix with gypsum powder for 2-3 minutes;

[0012] 5. Pour the mixed raw materials into the mold, spread the raw materials with a hot iron, and lift the mold with both hands to fully vibrate and shake;

[0013] 6. Press the back plate print on the raw material in the mold, remove the air holes, and clean the four sides;

[0014] 7. After 15 minutes of the whole operation and solidi...

Abstract

The making process of environment protecting composite ceiling board includes special surface treatment, including electrostatic spray to paint powdered paint to the surface of dried ceiling board blank and curing in stove at 280-330 deg.c for 3-5 hr. Thus produced ceiling board has hard surface and is scrubbing resistant, no aging, no color change, no deformation and no mould, and is fireproof,waterproof, and suitable for use in household, hotel and office.

Description

Technical field [0001] The invention relates to a method for manufacturing a ceiling. Background technique [0002] The ceiling products produced by the prior art have high strength, light weight, can be sawed and planed, and the manufacturing process is simple and convenient. However, the surface decoration (such as the surface covered with a layer of paint) is easily soiled, and the black mark produced by hand cannot be restored Defects in cleanliness. Summary of the invention [0003] In order to overcome the above-mentioned drawbacks, the purpose of the present invention is to provide a method for manufacturing a plastic-steel environmentally friendly composite ceiling, which is basically the same as the ceiling material produced by the prior art, has a similar appearance and structure, and has the advantages of easy cleaning, waterproof, and non-deformation. . [0004] In order to achieve the above objective, the technical scheme of the present invention is as follows: a ma...
