Combined door panel and its manufacturing process

Abstract

The invention discloses a combined door board and a manufacturing process thereof. The combined door board comprises a core board, a door frame and insertion strips. The middle of the door frame is provided with a cavity, one side of the door frame is provided with edge blocking strips on four sides of the cavity towards the inside side direction of the cavity, the inner sides of four sides of the door frame or the inner sides of any two opposite sides are provided with inserting grooves. The core board is arranged in the cavity in the middle of the door frame, and one side of the core board adheres to strips of the four sides of the cavity. The insertion strips are arranged on the core board, located on four sides of one face adhering to the edge blocking strips and inserted in the inserting grooves of the door frame. The insertion strips are fixedly connected with the core board through nails. The manufacturing process comprises the steps of respectively manufacturing the door frame, the core board and the insertion strips and respectively spraying paint; placing the core board at the right center of the middle cavity of the door frame; embedding the insertion strips into four sides of the core board and inserting the insertion strips into the inserting grooves; finally connecting the insertion strips with the core board through the nails. The door frame, the core board and the insertion strips are manufactured in advance and respectively sprayed with the paint, so that the edges of the core board of the assembled door board are prevented from being exposed after being contracted.

Description

technical field [0001] The invention relates to a wooden door panel, in particular to a combined door panel for preventing the door panel from showing white and a manufacturing process thereof. Background technique [0002] At present, the combined door panels on the market are all spray-painted as a whole, that is, after the overall production of the door panel is completed, the entire door panel is spray-painted. Under this method, the paint only covers the visible surface of the door panel. [0003] Due to the influence of ambient temperature, humidity and other factors, wood will expand with heat and contract with cold due to environmental factors. Therefore, at low temperatures, the core board of the composite door panel is easy to shrink, causing its four sides to be white. Contents of the invention [0004] In order to solve the above problems, the present invention provides a combined door panel and its manufacturing process which can effectively avoid the whitenin...
