Abstract

The invention discloses a method for preparing an air-conditioner indoor unit shell. The shell is manufactured by pulp die-pressing processing. The pulp die-pressing processing method comprises the following steps of: soaking a pulp board into emulsion for pulp die-pressing, removing redundant moisture from the wet pulp board through a roller to obtain the wet pulp board for pulp die-pressing, cutting the wet pulp board into boards slightly bigger than the inner surfaces of the dies according to the dimension sizes of the inner surfaces of a panel die-pressing forming die, an upper shell die-pressing forming die and a lower shell die-pressing forming die for the air-conditioner indoor unit shell respectively, and pressing the wet pulp boards into a panel, an upper shell and a lower required by the air-conditioner indoor unit shell on a pulp die-pressing forming machine by using the die-pressing forming dies respectively. The air-conditioner indoor unit shell produced by using the method has the characteristic of resisting water, corrosion, aging and flame, has light weight and low overall noise, is paint-free, and has low production cost.

Description

Technical field [0001] The invention belongs to the technical field of plastic processing, and relates to a method for preparing an air conditioner indoor unit casing. Background technique [0002] At present, the housings of indoor units of air conditioners on the market are all made of plastic particles by injection molding. These plastic housings have defects such as easy aging, easy discoloration, and high processing costs. Invention content: [0003] The purpose of the present invention is to provide a method for preparing a low-cost, low-carbon, and environmentally-friendly paper air conditioner indoor unit casing [0004] In order to achieve the above object, a method for preparing the housing of an air conditioner indoor unit of the present invention is made of pulp molding, and the pulp molding material is made of pulp board, styrene-acrylic emulsion, titanium dioxide, antimony trioxide, tetrabromobis Composed of phenol A, talcum powder, calcium carbonate, lithop...
