Problems solved by technology

[0002] The water pan is a commonly used device for collecting condensed water and draining water in air conditioners. However, the outer layer of the existing metal water pan uses PE insulation cotton. The PE insulation cotton has limited thermal insulation effect, and the PE moisturizing cotton is easy to be scratched during the installation and operation of the water pan. In addition, the welded drain nozzle is easily deformed, causing difficulty in drainage, easy to breed bacteria, and mildew

Embodiment 1

[0030] The polyurethane mixture includes the following components by weight: 90 parts of polyether polyol, 30 parts of perlite, 25 parts of chain extender, 8 parts of foaming agent, 4 parts of surfactant, compounded halogen-free flame retardant 10 parts, 3 parts of sodium citrate, 8 parts of sulfonated ricinoleol sodium salt, 5 parts of croscarmellose sodium.

[0031] The steps of polyurethane foaming are:

[0032] 1) Weigh the polyether polyol, chain extender, foaming agent, surfactant, compound halogen-free flame retardant, sodium citrate, sulfonated ricinoleol sodium salt, Croscarmellose sodium, stirred at 30-40°C to make a mixed solution;

[0033] 2) Weigh the perlite in the proportion by weight and add it to the mixed solution prepared in step 1), continue to stir, and keep it warm at 40-50°C for 30-50 minutes to prepare polyurethane foam, and put it in a vacuum at 60°C Dried in a desiccator for 40 hours, ready to use;

[0034] 3) The polyurethane foam prepared in step...

[0037] The steps of polyurethane foaming are:

[0038] 1) Weigh the polyether polyol, chain extender, foaming agent, surfactant, compound halogen-free flame retardant, sodium citrate, sulfonated ricinoleol sodium salt, Croscarmellose sodium, stirred at 30-40°C to make a mixed solution;

[0039] 2) Weigh the perlite in the proportion by weight and add it to the mixed solution prepared in step 1), continue to stir, and keep it warm at 40-50°C for 30-50 minutes to prepare polyurethane foam, and put it in a vacuum at 60°C Dried in a desiccator for 40 hours, ready to use;

[0040] 3) The polyurethane foam prepared in step 2...

Embodiment 3

[0042] The polyurethane mixture includes the following components by weight: 70 parts of polyether polyol, 30 parts of perlite, 20 parts of chain extender, 7 parts of foaming agent, 3 parts of surfactant, compounded halogen-free flame retardant 8 parts, 2 parts of sodium citrate, 7 parts of sulfonated ricinoleol sodium salt, 5 parts of croscarmellose sodium.

[0043] Further, the polyurethane foaming step in the step 3) is:

[0044] 1) Weigh the polyether polyol, chain extender, foaming agent, surfactant, compound halogen-free flame retardant, sodium citrate, sulfonated ricinoleol sodium salt, Croscarmellose sodium, stirred at 30-40°C to make a mixed solution;

[0045] 2) Weigh the perlite in the proportion by weight and add it to the mixed solution prepared in step 1), continue to stir, and keep it warm at 40-50°C for 30-50 minutes to prepare polyurethane foam, and put it in a vacuum at 60°C Dried in a desiccator for 40 hours, ready to use;

[0046] 3) The polyurethane foa...

Abstract

The invention discloses a water pond. The water pond comprises a pond body; pond body includes a plastic uptake liner, a side wall connected with the liner, and a drainage nozzle connected with the side wall; and a polyurethane foaming insulation layer is arranged on the outer side of the pond body. The invention further provides a production process of the water pond. Compared with the prior art, the insulation liner, obtained through plastic uptake, of the water pond is on the inner side of the pond body, and the outer surface of the pond body is the polyurethane foaming insulation layer, so that the pond body is not easy to be scratched, the insulation effect is good, and the strength is high; and the drainage nozzle is tightly connected with the side wall through polyurethane foaming, so that the drainage difficulty caused by welding deformation cannot be generated.

Description

technical field [0001] The invention relates to the technical field of air-conditioning fan coils, in particular to a water tray for central air-conditioning fan coils and a production process thereof. Background technique [0002] The water pan is a commonly used device for collecting condensed water and draining water in air conditioners. However, the outer layer of the existing metal water pan uses PE insulation cotton. The PE insulation cotton has limited thermal insulation effect, and the PE moisturizing cotton is easy to be scratched during the installation and operation of the water pan. In addition, the welded drain spout is easily deformed, making it difficult to drain water, and it is easy to breed bacteria and mildew. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a water tray with thermal insulation performance, thorough drainage, good anti-scratch performance. ...
