Wooden door machining method for improving thermal insulation performance

Abstract

The invention belongs to the field of furniture manufacturing, and particularly discloses a wooden door machining method for improving thermal insulation performance. The wooden door machining methodcomprises the following steps of grinding bentonite into powder, performing calcining at a high temperature, grinding together with diatomite to obtain mixed clay, and mixing with aluminum phosphate emulsion and water in proportion to obtain viscose; shearing aluminum silicate ceramic fibers and glass fibers to obtain mixed fiber powder, and then mixing with expanded graphite to obtain a mixed rawmaterial; and processing the viscose and the mixed raw material to obtain a molten feed liquid, performing spinning to obtain composite fiber yarns, preparing a composite thermal insulation board, and compounding the composite thermal insulation board with an external composite board to obtain the required wooden door. According to the wooden door machining method, the bentonite is calcined at the high temperature and mixed with the diatomite, thereby facilitating the intrusion of expanded graphite powder into micropores. The aluminum silicate ceramic fibers and the glass fibers are taken asthe raw materials, so that a good heat preservation effect is achieved. Meanwhile, the raw material is compounded with the aluminum phosphate emulsion, so that the bonding capability of each componentis optimized; a good environmental protection effect is achieved; the thermal insulation effect of each component can be brought into full play; and the thermal insulation performance of a door bodyis improved effectively.

Description

technical field [0001] The invention relates to the field of furniture manufacturing, in particular to a wooden door processing method for improving thermal insulation performance. Background technique [0002] The door is the guardian of our home safety. It not only plays the role of decorating the home, but also reflects the taste and pursuit of the owner. In recent years, beautiful, environmentally friendly and practical composite solid wood doors have been welcomed by consumers and become mainstream products in the decoration market. Composite solid wood doors not only retain the advantages of solid wood doors such as beauty and nature, heat preservation and moisture retention, and sound insulation, but also make up for their defects that are not easy to crack and deform. [0003] Thermal insulation is a basic functional requirement of wooden doors, and the speed of heat conduction of wooden doors determines the change of indoor temperature. The characteristics of exis...
