Flowerpot made of plant fibres and its manufacture method

Abstract

A flowerpot is made up by the plant fibres chosen from straw, stalk, husk, reed, grass, bamboo and wood and urea-formaldehyde adhesive through proportioning, pulverizing, mixing, wetting and die pressing. Its advantages are better water and air permeability and natural degradation of pot body by itself to supplement organic fertilizer.

Description

technical field [0001] The invention relates to a pot body material component of a plant fiber flowerpot and a manufacturing method thereof. Background technique [0002] In the prior art, there is Chinese patent 95111976.1 application disclosure specification related to the present invention. The plant fiber straw pulp board is used as the main raw material, and it is treated with a modifier, and the flowerpot is made by vacuum adsorption net molding. The grass used in this technology Pulp is not only relatively expensive, but also produces a large amount of waste water during the bleaching process of straw pulp, which seriously pollutes the environment. It is an industry strictly controlled by the state, and the source of straw pulp is restricted; in addition, the pulp molding process of this technology is complicated. It also consumes a lot of water (which can be called the pulp method). Due to the limitation of water resources, the product cost must be high; the filler t...

[0002] In the prior art, there is Chinese patent 95111976.1 application disclosure specification related to the present invention. The plant fiber straw pulp board is used as the main raw material, and it is treated with a modifier, and the flowerpot is made by vacuum adsorption net molding. The grass used in this technology Pulp is not only relatively expensive, but also produces a large amount of waste water during the bleaching process of straw pulp, which seriously pollutes the environment. It is an industry strictly controlled by the state, and the source of straw pulp is restricted; in addition, the pulp molding process of this technology is complicated. It also consumes a lot of water (which can be called the pulp method). Due to the limitation of water resources, the product cost must be high; the filler talcum powder and precipitant aluminum sulfate used in the formula weaken the air and water permeability of the pot body, which is not conducive to plant growth. growth; therefore, the technology is difficult to apply widely

Another related Chinese patent 91108365.0 and its later improved Chinese patent application 98111945.X use raw materials that can be used as feed (straw, corn cob, rice bran, etc.) Molding tableware and food packaging, less water consumption (can be called dry powder method), simple process, but this solution lacks a release agent, fillers such as talcum powder, calcium carbonate, clay and binders such as flour in the formula , rosin, and animal blood do not have a good demoulding effect, and it is difficult to realize industrial production; the same as the Chinese patent application 95111976.1, the filler talcum powder, calcium carbonate, and clay in the formula will also weaken the air and water permeability of the pot body and affect the plants. growth, therefore, this technique is not suitable for industrial manufacturing of plant fiber pots

There is also Chinese patent application 99113554.7 made of plant fiber, binding agent and release agent to make a seedling pot, wherein the bonding agent adopts flour, and the service life of the pot body is very short, which is suitable for seedling cultivation but not for flower planting
