Problems solved by technology

[0004] The filler talcum powder, calcium carbonate, and clay in the formulas of Chinese patent applications 95111976.1 and 98111945.X will affect the air permeability and water permeability of flower pots, and affect the growth of plants
In addition, the former uses pulp as raw material, which is highly polluting, and its products have poor mechanical processing performance, and cannot be made into complex structures to meet the needs of large-scale mechanized planting abroad; the latter lacks a release agent and is difficult to realize industrial production
[0005] Chinese patent application 99113554. Its adhesive uses flour, which has poor mechanical strength and short service life
[0006] Chinese patent 01113233.7 application described in the natural degradable environmental protection flowerpot production method is to use urea formaldehyde as adhesive, its disadvantage is poor degradation performance, it is difficult to degrade completely; the ratio of adhesive to plant fiber is 1: 1-1.2, too High adhesive ratio affects the production cost of the product
At the same time, because the product is prone to excessive free formaldehyde, it may affect the growth of plants
So far, there is no natural degradable environmental protection flower pot with practical value in the prior art

Embodiment 1

[0027] The manufacture method of the naturally degradable environment-friendly flowerpot of the present invention comprises the following steps:

[0028] ①. After crushing the plant fiber and adhesive, pass through a 60-100 mesh sieve to obtain the sieve material;

[0029] ②. Take 60 grams of sieved plant fiber and 40 grams of adhesive and put them into a mixer to stir to obtain a mixture;

[0030] ③. Add 1 gram of lubricant——zinc stearate and 5-10 grams of water to the mixture, and then stir well to obtain a molding material;

[0031] ④. Put the above molding material into the mold heated to 130-160°C, the pressure is 15-30Mpa, the pressing time is 0.4-1.5 minutes, and the middle exhaust is 1-3 times, and the product is formed;

[0032] ⑤. Take out the molded product, grind off the flash when it is still warm, and make a drainage hole at the bottom of the flowerpot. Wherein the adhesive in step 2 consists of 10 grams of oxidized starch, 10 grams of polyvinyl alcohol (PVA), ...

Abstract

The present invention relates to one kind of naturally degradable green flower pot and its making process. The naturally degradable green flower pot is made with crushed plant fiber and adhesive, and the adhesive is oxidized starch, PVA, PCL, amino plastic powder or their mixture. The making process includes the following steps: crushing the material, mixing, adding lubricant and water, stirring, molding to form, polishing and drilling holes. The naturally degradable green flower pot has the advantages of low cost and capacity of degrading naturally, has adjustable use period and strength and is suitable for planting various kinds of flowers especially in large mechanized plantation.

Description

technical field [0001] The invention relates to a naturally degradable environment-friendly flowerpot and a manufacturing method thereof. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, various flowers are becoming more and more popular, and planting and appreciating flowers have become a part of many people's lives. In order to reflect the prosperity and stability of the country and build a harmonious society, every May 1st, 11th, Spring Festival, New Year's Day and other holidays, a large number of flowers are placed on the streets of various places to celebrate. This greatly stimulated the development of the flower planting industry. [0003] At present, the flowerpots used for planting flowers include plastic flowerpots and ceramic flowerpots. Plastic flower pots are light in weight and can be made into various complex structures suitable for large-scale mechanized planting. However,...
