Referring to the first figure, in one aspect, the present invention discloses a straw manufacturing method and a composition thereof. The invention is almost free of plastic.

The steps of the present invention include preparing the paper, see step 110 of the first figure. After the process or after the pulp is completed, the natural enzyme or nano silver is added to facilitate sterilization after the product is completed, step 120.

The paper is crimped into a tube, and step 130, in order to facilitate the formation of airtightness, may be at least partially overlapped, preferably at least 20% of the surface area overlap, and in one embodiment two circles overlap.

Subsequently, in step 140, the inner and outer membranes may be coated with a water repellent (hydrophobic) membrane. For example, a hydrophobic material may be used, including an alkane, an oil, a fatty substance, or any combination of the above. In another embodiment, PP or PE can be used to increase the usability in the liquid. In another embodiment, a lotus effect can be utilized, based on which a biomimetic superhydrophobic substance, such as a nanopin film made by Nanotechnology, is utilized. When the contact angle of the cone material is sufficiently large, Cassie's law predicts the large contact angle value of the composite. This special nanofilm can use borosilicate glass as the main substrate and CoCl ₂ . A solution of 6H ₂ O or cobalt chloride hexahydrate in a chemical bath deposition at 60 ° C for 24 hours to form a composition having a layer of brucite-type cobalt (II) hydroxide Co. _1.13 Cl _0.09 (CO ₃ ) _0.39 .0.05 H ₂ 0. This step can be implemented before step 130.

In another embodiment, the extension molding can be utilized: that is, inflating with compressed air in the film tube, and depending on the thickness of the manufacturing, the rotation speed and the amount of extrusion are used to cause the paper tube to expand outward. The lateral and longitudinal extensions are followed, and the thickness adjustment and the extrusion volume of the extruder are selected in accordance with the requirements of the product thickness. The paper film is then separated. Subsequently, the surface of the paper film can be treated with a surface corona treatment machine as in the prior art, and a number of fine pores are formed on the surface by the corona discharge treatment, so that the surface has a better adhesion when coated. The thickness of the environmentally friendly paper can be controlled between 30 microns and 150 microns in the process. The above base material, silicone rubber and auxiliary agent are mixed, extruded and mixed into a pellet, and put into a molding machine for forming. Some papers need to be surface coated to make a matte or glossy surface. The surface coating may be an oil coating liquid.

In order to improve the toughness of the straw only, an appropriate amount of titanium dioxide, cerium oxide, a polymer material such as polypropylene, polyethylene, and an auxiliary agent may be added, and the mixture is mixed and extruded to form granules, which are put into a manufacturing machine for production adjustment to produce 20 micrometers and 55 micron paper substrate. The shaped substrate is placed in a molding apparatus and the temperature is controlled to soften the row of substrates to facilitate molding.

In another embodiment, part or all of the pulp may be replaced by an eggshell, a shell or a crustacean, and a straw substrate preparation method comprising the preparation base material comprising one or any mixture selected from the group consisting of an eggshell, a shell or a crust; The shell-based material is ground into particles; the above-mentioned ground particles, cerium oxide, polymer materials and auxiliary agents are mixed and mixed, and the particles, the cerium oxide, the polymer and the auxiliary agent are used to form a shaped substrate; And molding the substrate into a molding device and controlling the temperature to soften the row of substrates to facilitate molding. The cerium oxide is selected from the group consisting of silicone rubber, glass, or any combination. Wherein the shell base material comprises 28 to 35% by weight of eggshell, shellfish or crustacean; wherein the ceria comprises 25 to 30% by weight; wherein the auxiliary comprises 1 to 2% by weight; the polymer material comprises 28 to 38% by weight.

Another embodiment is to use an amylogenic material (such as polylactic acid) or a wax (such as beeswax or palmow wax) as a water repellent film to increase the usability in a liquid. Beeswax has a melting point between 62 and 64 degrees Celsius. The beeswax begins to change color when heated above 85 degrees Celsius. Its main components are palmitate, palmitoleate, hydroxypalmitate and long-chain fatty alcohols. Palm wax is a plant material, a vegetable wax, and an important non-petroleum wax.

In another embodiment, the starch biomaterial may be employed as the straw body or mixed with the paper fibers as the straw body. The monomeric lactic acid of polylactic acid can be synthesized by chemical synthesis or renewable resources. Generally, starch extracted from corn and cassava, sugar and cellulose extracted from sugar cane and sugar beet are obtained, and lactic acid is obtained through fermentation, dehydration and the like. The obtained lactic acid needs to be purified to produce polylactic acid. Compared with other biodegradable materials, polylactic acid has hydrophobicity by processing such as extrusion, injection molding and stretching, and polylactic acid can be formed into a desired shape and film.

Referring to the second figure, a method for making an environmentally-friendly straw comprises: preparing starch as a straw material (210); fermenting the straw material to produce lactic acid (220); fermenting the lactic acid into a raw granule (230); Formed into a hollow tube (240) into the forming machine. The starch raw material further comprises any combination of bamboo, corn stem, wheat stem, rice stem, orange stem, coffee grounds, bagasse or any combination thereof. Wherein the straw material further comprises cellulose, and the environmentally-friendly straw comprises lactic acid D-form (type), L-form (type) or any combination of the above. Natural enzymes or nanosilver may be added during, before or after the forming step 240 to facilitate sterilization after completion of the article.

The polylactic acid raw material is derived from corn, wheat, sweet potato and other crops, and includes corn stems, wheat stems, rice stems, bagasse, and the like. The starch is completely extracted from the plant raw material, and is produced by a polymerization process such as fermentation, and can be completely decomposed by the microorganism to finally generate carbon dioxide and water. Mixing two lactic acid D-forms (D-forms) and L-forms (L-types) (Poly(D, L-lactic acid)) in a specific ratio can make the material properties of polylactic acid stronger and longer.

An environmentally friendly straw comprises a hollow tube body comprising starch and fibers distributed in a hollow tube body; wherein the starch and fiber are taken from paper (fiber), corn stem, wheat stem, rice stem, coffee ground, bagasse, potato Any combination of one or more. Composed of starch or thermoplastic starch (TPS) with different physical or chemical properties. The main materials are potato starch, paper fiber (raw pulp) and additives, and the products are produced by an injection molding process. The composition of the starch is about 60 to 70%, the paper fiber is 30 to 20%, and the rest is an additive having a biodegradable product.
