Description

MANUFACTURING METHOD OF A PRO-ENVIRONMENTAL VEGETABLE FIBER REPLACING WOOD, PAPER AND PLASTIC}

The present invention relates to a method for manufacturing environmentally friendly plant fiber molding that can replace wood, paper, and plastics. In particular, the present invention relates to a plant fiber that can replace wood, paper, and plastic using various crop residues and plant wastes. It relates to a manufacturing method.

Although plastics and paper products provide simple and inexpensive products, due to advances in industrial technology, plastics do not decompose and combust and release hazardous waste, cause environmental pollution, and in large quantities due to the large demand for wood and pulp. The forests have been destroyed, slowing mankind's reforestation and failing to meet demand. This not only destroys the ecological environment, but also increases the carbon dioxide content in the atmosphere, gradually increasing the temperature of the earth and increasing the global greenhouse effect. As a result, technical workers in the plastics industry are devoted to the study of degradable plastics, while technical workers in the wood and pulp industry are improving various plywood and alternative paper materials and recovering papers. In the end, use is not avoided, and high alkaline wastewater is generated during the production of the recovered pulp, which seriously contaminates the freshwater source. Therefore, the most effective solution is to manufacture environmentally friendly materials using various wastes.

The main object of the present invention is to provide an environmentally friendly plant fiber molding manufacturing method that can replace wood, paper materials, plastics, and in particular, processing and manufacturing fiber granules, plates and paper products using crop residues and plant wastes. By doing so, eco-friendly and energy-saving effect will be achieved.

Eco-friendly plant fiber molding manufacturing method that can replace the wood, paper materials, plastics, mainly by pulverizing the crop residues or plant wastes into powder, and then to add the specialty, plasticizers, additives, Among them, crop residues or plant wastes include 63 to 73%, starch 15% to 20%, plasticizer 7%, and additives 5 to 10%. In the manufacturing process, the crop residue, starch, plasticizer and additives are sufficiently mixed with a high speed mixer according to the required proportion, followed by pressure mixing with a double screw machine, followed by crushing with a grinder and pressing with a press, followed by a mold temperature controller. Furnace temperature is controlled to 160 ~ 180 ℃ and put into a cooling system to form an eco-friendly plant fiber work masterbatch, the eco-friendly plant fiber work masterbatch is the wood, plate, paper by extrusion of the extruder or injection of the injection molding machine Manufactured from ash and molded to replace various wood, paper and plastics, for example, interior and exterior packaging and corners and corrugated boxes, paper boxes or vacuum molding machines. And also replace various plastics directly by molding with an injection molding machine using a plant fiber working masterbatch The injection can be achieved can be formed, and further the work of plant fiber or plastic timber with a master batch, a bar can replace several products made of paper material, environment-friendly and energy-saving effect.

1 is a block diagram of a manufacturing method according to the invention.

In order to help examiners understand the manufacturing method and the effect of the present invention, the present invention will be described below with reference to the accompanying drawings.

Referring to Figure 1, the plant fiber that can replace the wood, paper materials, plastics of the present invention, after grinding or cutting the crop residue or plant waste into powder, and then added starch, plasticizer, additives, Molded by eggplant processing, among which crop residues are rice, wheat, palm husk, sugar cane waste, etc., plant wastes are wood chips, tree branches, tree leaves and non-toxic waste furniture, pallets, etc. Industrial starch, plasticizer is a plastic masterbatch, additives are dispersants, adhesives and resins, of which the proportion of crop residues or plant wastes is 63-73%, the proportion of starch is 15% -20%, The proportion is 7% and the proportion of the additive is 5 to 10%. As a manufacturing method, after grinding the crop residue or plant waste into 60 ~ 200 mesh, the starch, plasticizer, and additives are classified according to the product type, and then sufficiently mixed with a high speed mixer according to the required proportion to become sticky. After mixing, press the double screw machine, pressurize and mix thoroughly at high temperature and high pressure, extrude into a stick or annular shape, grind with a grinder and press with a press, then control the temperature to 160 ~ 180 ℃ with a mold temperature controller and cool After cooling and wind shearing put into the system form eco-friendly plant fiber working masterbatch.

Plant fiber working master batches made from 60-100 mesh crop residues or plant waste powders are directly extruded from an extruder and made directly from wood, boards, or by various wood substitutes by mold temperature controllers and cooling systems. Bars that can be molded include, for example, interior edges and boards or stair railings, furniture, veneers, and contact plates, and since the wood and the plates themselves do not contain formaldehyde, the high-quality wood and boards of eco-friendly interiors. In addition, furniture can be replaced, and flame retardants can be added to produce fireproof building materials.

Plant fiber working master batches made from 100-150 mesh crop residue or plant waste powder can be directly injection molded by an injection molding machine to replace various plastic products, for example toothbrushes, combs, etc. Disposable products such as blood sugar needles, pregnancy test rods, ballpoint pen outlines, and the like.

Plant fiber working master batches made from 150-200 mesh of crop residues or plant waste powders are produced in paper boards, paper boxes and paper boxes, or by vacuum forming machines, in and out of cartons and various paper products, for example Paper slippers, cardboard boxes, electronics liners, new liners, and dressing liners.

Since the product can directly replace wood, paper and plastic, it can meet the requirements of eco-friendliness, and also waste of resources because most raw materials use crop residues or plant waste that are no longer used. Can be prevented, energy can be saved, and more importantly, the manufacturing method according to the present invention does not completely discharge wastewater and waste during the manufacturing process, and thus does not cause water source and environmental pollution, The manufactured product can be completely recovered and reused.
