Abstract
Abstract of the Disclosure A biologically resolvable blind slat and the manufacturing method therefor, wherein PVC powders serve as a basic material and are added with stabilizer, lubricant, calcium carbonate and surface-treated starch to mix therewith, the mixture being processed by a granulating machine into granules which are further heated and pressed by a press machine into strips, the strips being then cut into blind slats in a certain pattern and at a certain length.
Description
20~9~01 A Biologically Resolvable Blind Slat and Manufac ~ erefor Background of the Invention Ihe present invention relates to a biologically resolvable blind slat and the manufacturing method therefor, wherein PVC powders serve as a basic material and are added with stabilizer, lubricant, calcium carbonate and surface-treated starch to mix therewith, the mixture being processed by a granulating machine into granules which are further heated and pressed by a press machine into strips and the strips are then cut into blind slat in a certain pattern and at a certain length. Such blind slat is biologically resolvable and can be made with a colorful drawing on the surface thereof to improve the appearance thereof.
Convention blind slats are mainly made of plastics or made of wood or metal. Ihe light-shielding effects thereof are substantially the same. Ihe wooden blind slat after discarded can be burned off to avoid causing environment pollution. However, the wooden slat is made at high C09t and the manufacture thereof is relatively difficult. Moreover, such slat is apt to fissure after a long term of exposing to sunlight. Iherefore, such ~slat is not durable. As to the metal slat, after .

Convention blind slats are mainly made of plastics or made of wood or metal. Ihe light-shielding effects thereof are substantially the same. Ihe wooden blind slat after discarded can be burned off to avoid causing environment pollution. However, the wooden slat is made at high C09t and the manufacture thereof is relatively difficult. Moreover, such slat is apt to fissure after a long term of exposing to sunlight. Iherefore, such ~slat is not durable. As to the metal slat, after .
1.
2~9~1 discarded, the metal slat can be recovered to avoid cau~sing environment pollution~ However, the cost thereof is high and surface-processing thereof is difficult. Also, metal slat i9 apt to be bent and distorted while unable to restore to its original shape.
Plastic slat is made at low cost and easily manufactured and such slat is durable. However, plastic slat after discarded will not be naturally resolved so as to cause environmental contamination. If such slat is processed by burning, air pollution will inevitably take place.
Moreover, the above three types of blind slats after manufactured, are difficult to be made with any colorful drawings thereon so that these slats can only shield the sunlight while failing to produce decorative effect.
Iherefore, a blind slat which can be easily manufactured at low cost and which can be naturally resolved after discarded to avoid causing environment pollution and which can be freely made with desired colorful drawings thereon is needed.
Summary of the_Invention It is a primary object of this invention to provide a biologically resolvable blind slat wbich possesses the advantages of a plastic blind slat while able to eliminate the problem of environment pollution.
2.
20~9~3 Moreover, such blind slat can be made with colorful drawings thereon by the user to improve the decorative effect.
According to the above object, the present blind slat is made in such a manner that surface-treated starch and stabilizer, lubricant and calcium carbonate are added to and evenly mixed with PVC powder which serves as a basic material and then the mixture is processed by a granulating machine into granules.
Color powder can be directly added to the mixture to form a desired color of blind slat.
- Ihe above biologically resolvable blind slat i9 manufactured in such a manner that the surface-treated starch, PVC powder, stabilizer, lubricant and calcium carbonate are mixed evenly and then the mixture is processed by a granulating machine into granules which are further heated and pressed by a press machine into strips. Ihe ~trips are then cut into the blind slats in a desired pattern and at a desired length.

Ihe blind slat of this invention i9 manufactured in such a manner that stabilizer and calcium carbonate are added to PVC granules and surface-treated starch and mixed therewith, and then the mixture is heated and 3.
20~9~1 processed by a granulating machine into granules which ~re further heated and pressed by a press machine into strips and then the strips are cut in a certain pattern and at a certain length into the slats.
Ihe mixture is formed at such a composition ratio that 95 kilogram PVC powder, 4 kilogram stabilizer, kilogram lubricant, 45 kllogram calcium carbonate and 10 kilogram starch are evenly mixed.
Ihe slat formed by the above compositions due to PVC property possesses corrosion-resistance, appropriate rigidity and collision-resistance and will not suffer efflorescence and thus can be durably used. In addition, due to the added surface-treated starch, the blind slat is formed with fine holes on its surface and thus like a paper, can be made with a colorful drawing thereon while still keeping the regidity and collision-resistance. Particularly, general starch will be burned black at about 96C while the surface-treated starch used in this invention can stand high temperature up to 250 C. Moreover, such starch can cooperate with the stabilizer, calcium carbonate and lubricant to evenly mix with the PVC so that the PVC particles can closely combine with the starch molecules to maintain the original rigidity and collision-resistance of the PVC
and starch materials while further having the heat-, 2059~1 resistance. Moreover, when the slat is burled in the ground, the starch will be resolved biologically and totally disappear from the ground after one and half years to two years. Iherefore, the environmental S contamination is eliminated.
When manufacturing the above blind slat, the color po~der can be directly added into ~he composltions to form a desired color of blind slat.
Ihe biologically resolvàble blind slat is ~ manufactured in such a manner that the aforesaid compositions is heated by a press machine at about 230C
and then the heated material is pressed into strips with equal width ~hich is then cut in a certain pattern and - , .
