A kind of thermal insulation and sound insulation environmental protection solid wood composite door

Abstract

The invention discloses a thermal insulation, sound insulation and environmental protection solid wood composite door, which relates to the technical field of production and processing of solid wood composite doors. In order to solve the problem of sound insulation of the existing solid wood composite doors, a bridge cavity mechanical plate is generally used for sound insulation, but the noise decibel is as high as When it is fifty decibels and above, its sound insulation effect begins to show obvious deficiencies, and we need to strengthen it. The inside of the solid wood composite door body is provided with a solid wood keel board, and the outer walls of the upper and lower ends of the solid wood keel board are provided with high-density boards, and the high-density board is fixedly connected with the solid wood keel board, and the outer wall of the high-density board is provided with There is a solid wood cortex, and the solid wood cortex is fixedly connected with the high-density board, and the inner wall of the high-density board is provided with noise reduction through holes, and the noise reduction through holes are fixedly connected with the high density board, and there are several noise reduction through holes. A sound-absorbing sponge body is arranged inside the noise-reduction through hole, and the sound-absorbing sponge body is fixedly connected with the noise-reduction through hole.

Description

technical field [0001] The invention relates to the technical field of production and processing of solid wood composite doors, in particular to a thermal insulation, sound insulation and environmental protection solid wood composite door. Background technique [0002] Solid wood composite door refers to a solid or close-to-solid body made of wood, glued wood, etc. as the main material. The surface layer is a door made of wood veneer veneer or other cladding materials. It is made of pine wood, fir wood or imported filling materials, pasted with density board and solid wood veneer, made after high-temperature hot pressing, and sealed with solid wood lines. Generally advanced solid wood composite door, the door core is mostly high quality white pine, the surface is solid wood veneer. Due to the low density, light weight and easy control of the moisture content of white bulk, the weight of the finished door is relatively light. [0003] However, the existing solid wood compos...
