Problems solved by technology

[0002] The traditional production process of upholstered furniture sofas generally includes: inner frame cutting, drilling, and nailing; inner frame accessories nailing, pasting and priming; cutting and sewing of surface attachments; Covers and finished products are installed, and accessories are assembled to complete a finished sofa. This process is complicated, and the quality defects of each process may cause problems in the final process and effect of the product, which will bring certain problems to the appearance, function and comfort of the product. influences
In addition, the structure and production of the inner frame in the traditional sofa production process have defects such as stability and time-consuming production, which cannot quickly and effectively shape the product. In addition, the surface coat sample of the product is hand-made and cut and sewn. Make the product process unstable and the process time-consuming, etc.

Embodiment 1

[0026] A kind of generation technique of spraying molding sofa is characterized in that comprising following process step:

[0027] 1) Take polyether box-type foam sponge, the polyether box-type foam sponge has a net density of 36-50 kg / m3 and no chemical fiber reinforced plastics;

[0028] 2) Use a CNC sponge cutting machine to cut the foam material to form a sofa-shaped sponge;

[0029] 3) Configure surface coating agent A and surface coating agent B. The surface coating agent A consists of 85 parts by weight of polyurethane prepolymer, 8 parts by weight of polycarbonate, 1 part by weight of defoamer 6800, oxalic acid 6 parts by weight of succinate were mixed and then heated to 80°C for 5 hours to react. The surface coating agent B consisted of 66 parts by weight of toluene diisocyanate, 20 parts by weight of isophorone diisocyanate, 5 parts by weight of propyl carbonate, and 5 parts by weight of alcohol, 2 parts by weight of antibacterial nano-powder and 2 parts by weight ...

Embodiment 2

[0041] A kind of generation technique of spraying molding sofa is characterized in that comprising following process steps:

[0042] 1) Take polyether box-type foam sponge, the polyether box-type foam sponge has a net density of 36-50 kg / m3 and no chemical fiber reinforced plastics;

[0043] 2) Use a CNC sponge cutting machine to cut the foam material to form a sofa-shaped sponge;

[0044] 3) Configure surface coating agent A and surface coating agent B. The surface coating agent A consists of 88 parts by weight of polyurethane prepolymer, 5 parts by weight of polycarbonate, 0.5 parts by weight of defoamer 6800, oxalic acid 6.3 parts by weight of succinate were mixed and heated to 70°C for 6 hours to react. The surface coating agent B was made of 60 parts by weight of toluene diisocyanate, 25 parts by weight of isophorone diisocyanate, 8 parts by weight of propyl carbonate, and 5 parts by weight of alcohol, 1 part by weight of antibacterial nano powder and 1 part by weight of...

Abstract

The invention discloses a technology for producing a sofa through spraying moulding. The method comprises the following steps: preparing a foam cotton material; cutting the foam cotton material; preparing a surface coating agent; coating the surface; drying a coating layer of the surface; preparing a bottom coating layer; coating the bottom; drying the coating layer at the bottom; processing surface texture; spraying a color layer; stabilizing UV color; drying the material; and packaging the product and storing the product. The technology solve the problems of non standard production of an internal frame of the product, coat cutting and sewing, low efficiency, and unstable technology.
