However, the current floor heating laying is to lay a thicker layer of benzene board on the building structure layer, and then lay the floor heating water pipe on the benzene board. Due to this laying method, the strength of the floor heating benzene board is limited, which requires a thicker layer when laying, and the overall laying thickness is 80 mm to 100 mm. In addition, the benzene board needs to be laid on-site with floor heating water pipes, wh

Abstract

The invention relates to a method for coating a thin floor-heating insulation benzene plate. The method comprises the following steps of: material charging, i.e., charging polystyrene particle materials into a ready-made die cavity; die closing, i.e., introducing super-heated steam into the die cavity until the die cavity is completely full of polystyrene; first die opening, i.e., carrying out vacuum pumping until completely pumping the steam to dry, thus forming a polystyrene foaming benzene plate; coating, i.e., adding a polystyrene sheet material between the benzene plate and a die upper plate; die semi-closing, i.e., introducing super-heated steam into the die cavity; die closing, i.e., carrying out die closing and pressing, and meanwhile introducing super-heated steam into the die cavity; second die opening and die releasing; and trimming, i.e., cleaning the edge of the benzene plate. When the coated polystyrene benzene plate prepared by the method is used for fixing a floor-heating water pipe, the pipe material is unlikely to be damaged since the strength of the pipe material is protected; and the pipe material is unlikely to deform after being fixed, and the pressure bearing capacity of the foaming benzene plate is enhanced.

Description

technical field [0001] The invention relates to a film-coating method of a benzene board, in particular to a film-coating method of a thin floor heating and thermal insulation benzene board. Background technique [0002] Traditional floor heating (80 floor heating) has been accepted by more and more users as a heating method. It has many advantages such as comfort, energy saving, low level of heat source requirements, and saving room space. However, when laying floor heating now, a thicker layer of benzene board is laid on the building structure layer, and floor heating water pipes are laid on the benzene board. Due to this laying method, the strength of the floor heating benzene board is limited, which requires a thicker layer when laying, and the overall laying thickness is 80 mm to 100 mm. In addition, the benzene board needs to be laid on-site with floor heating water pipes, which will cause on-site installation. etc. are greatly affected by the technical level of the ...
