Embodiment 1

[0050] Embodiment 1, a kind of decorative suspended ceiling, such as figure 1 As shown, it includes a keel assembly, a gypsum board 1 arranged on the lower end surface of the keel assembly, and the outer wall of the gypsum board 1 is coated with a putty layer 2 and a latex paint layer 3 in sequence. Wherein, the construction method of the suspended ceiling includes the following steps:

[0051] Step 1, grass-roots treatment: before the construction of the ceiling, clean up the blockage of the pipe hole, and clean up the sundries on the top;

[0052] Step 2, measuring and setting out: According to the construction requirements, pop up the ceiling keel line on the top of the wall as the standard line for installation;

[0053] Step 3, install the keel: connect the main keel to the hanger with a pendant and fix it with bolts, and continue to install the auxiliary keel, cross brace keel and side keel to form a keel assembly;

[0054] Step 4, install gypsum board 1: fix gypsum bo...

Embodiment 2

[0056] Embodiment 2, by weight, latex paint layer 3 raw material components are as shown in table 1, and this latex paint layer 3 is prepared through the following steps: Step 1, the preparation of seed emulsion: get lauryl sulfate ammonium salt 2 1 part, 1 part of sorbitol monooleate was added to the reaction bottle and diluted with ionized water to a thick state and stirred evenly. Fill the reaction bottle with nitrogen and raise the temperature to 70-80°C, keep it for 0.5h, and add 1 part of potassium persulfate , 50 parts of methyl methacrylate and 25 parts of butyl acrylate initiate the polymerization reaction, wherein the mixture of methyl methacrylate and butyl acrylate is controlled to be added to the reaction bottle by dropwise within 3-4h, Stir continuously during the addition process, and keep warm at 70-80° C. for 2 hours to obtain seed emulsion.

[0057] Step 2, preparation of core-shell polymerization emulsion: Add 2 parts of lauryl sulfate ammonium salt, 1 part ...

Embodiment 3

[0059] The difference between embodiment 3 and embodiment 2 is that, in parts by weight, the raw material components of latex paint layer 3 are as shown in table 1.

Abstract

The invention discloses a decorative suspended ceiling and a construction method thereof and relates to the field of decoration. The suspended ceiling comprises a gypsum board, wherein an outer wall of the gypsum board is coated with a putty layer and a latex paint layer in sequence; raw materials of the latex paint layer comprise the following components in parts by weight: 100 to 140 parts of methyl methacrylate, 50 to 100 parts of butyl acrylate, 1 to 5 parts of acrylic acid, 3 to 12 parts of an emulsifier and 1 to 5 parts of potassium persulfate. The decorative suspended ceiling disclosedby the invention has the following beneficial effects that the raw materials can be prepared into core-shell polymerization type latex paint. Compared with traditional latex paint, the core-shell polymerization type latex paint has good waterproof and damp-proof performance and has better physical and mechanical comprehensive performance. The acrylic acid has a polar group, and the polar group canbe introduced into a side chain of a polymer, so that the attachment force between the latex paint layer and the gypsum board is increased; the acrylic acid has a good effect of improving a polymerization technology, can be dissolved into a water phase and also can be dissolved into an oil phase, and can be used for effectively inhibiting the generation of gel; and meanwhile, synthesized emulsionhas good mechanical performance and storage stability.

Description

technical field [0001] The invention relates to the field of decoration, in particular to a decorative suspended ceiling and a construction method thereof. Background technique [0002] Suspended ceiling refers to a kind of decoration on the top decoration of the living environment of the house. Simply put, it is the decoration to the ceiling and is one of the important components of interior decoration.
