Description

Environmental protection interior door

Technical field

The present invention relates to a kind of building door, especially a kind of environmental protection interior door.

Background technology

Interior door produced in the market is mainly based on timber.Timber can be divided into former Solid Door, solid wood finger-jointed plate door, solid wood composite door, molded door, high score cervical orifice of uterus, steel timber, PVC door and flush door etc.

1, former solid wood timber draws materials to make a core from the natural wood of forest, then through blanking, scrape, mortise, perforating, engraving, the operation science processing such as sizing makes.

2, solid wood finger-jointed plate door refers to the timber of log after sawing, finger, and through the timber that the operation that log Solid Door is identical is processed into, performance is much more stable than log Solid Door, not yielding.Mostly timber selected by full Solid Door is famous and precious timber, as cherry, walnut, teak etc.

3, the door leaf border of solid wood composite door uses China fir or pine, the structures such as central filler honeycomb paper, density board grid, bridge mechanical plate, solid wood, surface layer base material uses medium density fibre board (MDF) or perforated particleboard, various famous and precious solid wood veneer is pasted on surface, make after high temperature hot pressing, and use solid wood line edge sealing.Generally senior solid wood composite door, its Men Xin mostly is high-quality kahikatea, and surface is then plates of solid wood.

4, clamping plate mold pressing hollow-core door does framework with solid wood, and two sides decorative sheet is sticky to be pressed on framework, is processed into through hot pressing.Clamping plate mold pressing hollow-core door door core, framework are main mainly with pine, and style is single, and structure is simple, and gate limits by shape of template, and concrete other customization size may be out of proportion.

Wooden indoor door is mainly derived from the pure natural timber of the Nature due to material, even in order to improve interior door class, adopts some precious timbers as starting material, is a kind of destruction virtually like this to large natural environment.From production angle analysis, wooden indoor door, by carrying out carving on log basis or the technology such as hollow out is processed, is also constructed by carrying out the technology such as mold pressing to timber and other components.

For the interior door of engraving or the processing of the technology such as hollow out, for material itself and processing units accuracy requirement higher, cause cost quite high, production marketing selling at exorbitant prices.

By post-production technology such as mold pressings, the apparent moulding of door leaf is comparatively simple, single, and size is unstable control, and cause overall door leaf Quality Down, soundproof effect is relatively poor, and moisture protection is more weak, and work-ing life is short.

Summary of the invention

The invention provides a kind of environmental protection interior door making full use of waste.

Realize the environmental protection interior door of the object of the invention, comprise magnesium oxide, magnesium sulfate, agriculture and industry waste, whipping agent, composite modifier, compound water retaining agent, composite emulsion, PP fiber and fibrous mesh cloth and formed by pulverizing, fusion, mold pressing;

Described magnesium oxide 42.5 ~ 44.5%; Described magnesium sulfate 20.2 ~ 25.5%; Described agriculture and industry waste 9.5 ~ 11.5%; Described whipping agent 1.7 ~ 2.1%; Described composite modifier 1.6 ~ 1.9%; Described compound water retaining agent 0.01%; Described composite emulsion 0.08%; Described pp fiber 0.18 ~ 0.25%; Described fibrous mesh cloth 20 ~ 27%.

Described agriculture and industry waste is one or more in flyash, silicon ash, vegetable fibre, coal gangue, page rock, glass, iron tailings, jade mine tailing, grain slag, mica mine tailing or stalk.

The beneficial effect of environmental protection interior door of the present invention is as follows:

Environmental protection interior door of the present invention, by adopting some wastes such as industrial refuse, agricultural waste to be raw material, making environmentally-friendly sanitary product, solving and cause the problems such as environmental disruption because adopting a large amount of timber at present, meanwhile, the destruction that waste causes environment is also solved.
