Description

High-strength energy-storage heat-preservation door

Technical Field

The utility model relates to a door industry field especially relates to a high strength energy storage heat preservation door.

Background

Traditional heat preservation door that gives sound insulation fills foam cement in the internal portion of door, though foam cement can realize giving sound insulation and heat retaining effect, foam cement intensity is low, thereby the door can break or the fracture can cause the door body to lose sound insulation heat retaining function through its inside foam cement of long-time back of using. With the increasing noise pollution and the demand for energy conservation, a high-strength sound-insulation heat-preservation door is particularly important.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a high strength energy storage heat preservation door, this kind of door adopt multiple function material composite construction for the door body that makes has energy storage heat preservation and syllable-dividing effect.

The above technical purpose of the present invention can be achieved by the following technical solutions: the high-strength energy-storage heat-preservation door comprises a bamboo charcoal magnesium oxychloride cement foaming plate, non-woven fabrics, a phase change layer, a buffer layer and a plastic diaphragm, wherein the bamboo charcoal magnesium oxychloride cement foaming plate, the non-woven fabrics, the buffer layer and the phase change layer are arranged in a door body frame, the non-woven fabrics are covered on the upper surface and the lower surface of the bamboo charcoal magnesium oxychloride cement foaming plate, the buffer layer is arranged on the non-woven fabrics on the upper surface of the bamboo charcoal magnesium oxychloride cement foaming plate, the phase change layer and the buffer layer are further arranged on the non-woven.

The door body frame is made of wood materials.

The buffer layer is soft foamed plastic, preferably is made of one of foamed polyurethane and foamed ethylene vinyl acetate copolymer, and has a thickness of 2-5 mm.

The phase change layer is a polyethylene glycol film, the molecular weight of the polyethylene glycol is preferably 2000-10000 for realizing phase change energy storage, and the thickness of the film layer is 2-5 mm.

The plastic diaphragm wraps the bamboo charcoal magnesium oxychloride cement foam board, the non-woven fabric, the phase change layer and the buffer layer into a whole, and the interface between the multilayer materials is bonded by adopting an isocyanate adhesive so as to facilitate the production and processing of the wooden door.

To sum up, the utility model discloses following beneficial effect has: the bamboo charcoal magnesium oxychloride cement foam board is used as a core board, and the upper surface and the lower surface of the core board are covered with non-woven fabrics to enhance the strength of the bamboo charcoal magnesium oxychloride cement foam board. Compared with other foam boards, the bamboo charcoal magnesium oxychloride cement foam board has higher strength and crack resistance. Have phase transition layer and buffer layer on the non-woven fabrics of this application in addition, the buffer layer can weaken the door body and spread the energy of bamboo charcoal magnesium oxychloride cement foaming board when receiving the impact for bamboo charcoal magnesium oxychloride cement foaming board is difficult for breaking, and the phase transition layer can further improve the thermal insulation performance of bamboo charcoal magnesium oxychloride cement foaming board, and it is more convenient that the plastics diaphragm becomes a body messenger's timber with multilayer composite construction and adds man-hour.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments or the technical solutions in the prior art will be briefly described below. Throughout the drawings, like elements or portions are generally identified by like reference numerals. In the drawings, elements or portions are not necessarily drawn to scale.

Fig. 1 is a schematic view of a door body structure according to a first embodiment of the present invention;

reference numerals: 1. bamboo charcoal magnesium oxychloride cement board; 2. non-woven fabrics; 3. a buffer layer; 4. a phase change layer; 5. a plastic diaphragm; 6. a door frame.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

The first embodiment is as follows:

the utility model provides a high strength energy storage heat preservation door, is including setting up bamboo charcoal magnesium oxychloride cement foaming board 1, non-woven fabrics 2, buffer layer 3, phase transition layer 4, plastic diaphragm 5 in door body frame 6, the surface covers has non-woven fabrics 2 about bamboo charcoal magnesium oxychloride cement foaming board 1, still has one deck buffer layer 3 on the non-woven fabrics 2 of its upper surface, still has one deck phase transition layer 4 on the non-woven fabrics 2 of its lower surface, plastic diaphragm 5 wraps up bamboo charcoal magnesium oxychloride cement foaming board 1, non-woven fabrics 2, phase transition layer 3, buffer layer 4 four-layer structure as an organic whole, and the interface between the multilayer material combines to adopt the isocyanate gluing agent.

The door body frame 6 is made of wood, the buffer layer 3 is made of soft foamed plastic, and the preferable material is foamed ethylene vinyl acetate copolymer with the thickness of 3 mm. The phase change layer 4 is a polyethylene glycol film, the preferred polyethylene glycol has a molecular weight of 3000 and a thickness of 2mm, and the polyethylene glycol can play a role in phase change energy storage.

The bamboo charcoal magnesium oxychloride cement foam board 1 is used as a core board, and the non-woven fabric 2 covers the upper surface and the lower surface of the core board to enhance the strength of the bamboo charcoal magnesium oxychloride cement foam board 1. Compared with other foam boards, the bamboo charcoal magnesium oxychloride cement foam board has higher strength and crack resistance. In addition there are buffer layer 3 and phase transition layer 4 on the non-woven fabrics 2 of this application, buffer layer 3 can weaken the door body and propagate the energy of bamboo charcoal magnesium oxychloride cement foaming board 1 when being strikeed for bamboo charcoal magnesium oxychloride cement foaming board 1 is difficult for breaking, and phase transition layer 4 can further improve bamboo charcoal magnesium oxychloride cement foaming board 1's thermal insulation performance, and it is more convenient that plastics diaphragm 5 becomes an organic whole with multilayer composite structure and makes the timber man-hour add.

Further, when the timber was used, the buffer layer orientation was outdoor, and the phase transition layer was indoor, and the buffer layer can absorb partial open air sound and weaken the energy that the external portion of door propagated the bamboo charcoal chlorine oxygen magnesium cement foaming board when being strikeed simultaneously, and the phase transition layer combines bamboo charcoal chlorine oxygen magnesium cement foaming board can play better heat preservation effect, through the utility model discloses a multilayer composite structure can realize a high strength, give sound insulation, energy storage heat retaining timber. The timber is after using for many years, even bamboo charcoal chlorine oxygen in the middle of the timber your cement foaming board fracture or break, through the utility model discloses a buffer layer and phase transition layer, the timber still can have better heat preservation sound insulation effect.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
