Description

A kind of louver lamina

Technical field

The utility model relates to building materials field, specifically is curtain blade, particularly louver lamina.

Background technology

Shutter all is widely used in countries in the world, especially with Southeast Asia, European various countries shutter is had permanent use tradition and preference; In the existing house ornamentation industry of China, the decorative product that shutter is also often selected for use, day by day become in the daily residential life one of the indispensable a kind of dwelling house of institute or institute of office articles for use, its predominant use promptly is in order to intercept sunlight or the purposes of the privacy of isolating sight line is provided.The curtain of now being sold is on the market mainly made by following different materials:

1, plastics and aluminium.This class curtain is light and handy, and processing and fabricating is simple and easy, but its pollution is big, very is unfavorable for environmental protection; Plastic louver is that plastic material adds chemical staining agent, adds the hot extrusion molding product, though have economical advantage such as easy to manufacture, with low cost, but its shortcoming is as follows: (1) elasticity is low, and flexural deformation damages, produces folding line easily, is unfavorable for the cleaning wiping of curtain; (2) coloring agent that adds in the plastics was easy to fade after sunshine, hindered attractive in appearancely, and the chemical staining agent that produces again can contaminated air; (3) day with high temperature photograph makes the plastics embrittlement, and shorten application life; (4) plastic shutter of Hui Huaiing, can't recycling and plastics can't in the short time, decompose, environmental pollution and load infringement are greatly.

2, timber.Wooden curtain sheet because of its quality is attractive in appearance, is subjected to liking of customer and curtain manufacturer deeply.But because in recent years, the over-exploitation of forest, because after country implemented protection to wildwood, operational timber was fewer and feweri, makes curtain if re-use timber, not only drawing materials is not easy, and can cause sizable destruction to environment; The price ordinary consumer of the louvre of making of solid wood is difficult to accept in addition.

3, bamboo.This class curtain is because quality is attractive in appearance, and the customer that also experiences likes.Though with respect to the above two processing technology complexity, careful because of the skin texture of bamboo itself, compressive resistance is strong, make that product is very practical outside, also because the bamboo growth fast, little to ambient influnence, become the best product that replaces wooden louvers for window.

But no matter be to have following point with timber or with the shutter that bamboo is made: the blade of louver window on the existing market generally adopts the timber or the bamboo of full wafer, require very high to drawing materials, particularly bamboo will find full wafer to be fit to do the not a lot of of blade of louver window, causes the raw material anxiety.In actual production, many thin narrow bamboo chip or bamboo silks can only be used for making ground cushion or seat cushion, and the area of ground cushion or seat cushion is bigger, can stay many clouts after reducing according to the customer requirement size, can only discard because area can't utilize inadequately.This can improve the manufacturer production cost undoubtedly, and under the abundant present situation of China's forest tree resource, this also is not environmental protection to raw-material waste.

The utility model content

For solving the problem that a large amount of thin narrow bamboo chip clout that sun blind production in the prior art adopts the problem of drawing materials that the individual layer integrated plate blade brings and bamboo production to exist is wasted, the utility model provides a kind of composite bed louver lamina.

The purpose of this utility model is that the thin narrow bamboo chip clout that makes full use of in the bamboo production is made a kind of composite bed louver lamina.

The technical solution adopted in the utility model is: a kind of louver lamina, described curtain blade have blade layer, inferior lobe lamella, go up back sheet, back sheet, support layer down, and support layer upper surface connects goes up back sheet, last back sheet connection blade layer; Support layer soffit connects back sheet down, and following back sheet connects the inferior lobe lamella; Blade layer and inferior lobe lamella are slice and form.

Described upward back sheet, following back sheet and support layer are composite bed; Described support layer, last back sheet and following back sheet are optional with paper material, cloth material, wood materials, bamboo material, plastic material, fibrous material or metal material.

Described blade layer is or/and the inferior lobe lamella can be wide slice composition; Can form for the slice that width differs.

Described slice comprises at least a in bamboo chip, wood chip, the scraps of paper, herbaceous stem thin slice and the cotton rope.

The utility model compared with prior art has the following advantages: 1, because adopt the structure of folded double, so in the blade production of sun blind, be not subjected to the restriction of bamboo chip width, broken through the pattern of existing individual layer full slice system louver lamina, the composite bed blade can more utilize bamboo resource, and raw material are abundant; 2, can utilize a large amount of thin narrow bamboo chip clout in the bamboo production fully, solve the big industry difficult problem in the current bamboo production, cost is more saved in environmental protection; 3, the two-sided blade of louver window of Zhi Zuoing has overcome the problem of blade of louver window burr.
