AI Technical Summary

Problems solved by technology

To sum up, the pollution problem cannot be completely solved, and the price is high; plant fiber pressing molding flowerpot: plant fiber has many uses, and using it to produce flowerpots will still cause a shortage of plant resources, and it will not solve the dust in the wood-based panel industry pollution problem
Using paper seedling pots, due to the use of chemical treatment methods in the early pulping process, not only corrosive strong alkali black liquor will be discharged, but also harmful waste residues and waste gases will be discharged, and the pollution of "three wastes" is serious
The price of paper seedling pots is too high, it is easy to be deformed by moisture, and it is difficult to use in automatic seedling production lines

Embodiment 1

[0015] Example 1: Using straw board sanding powder as the main raw material, the weight of the finished flowerpot is 500g, and the specific manufacturing process steps are as follows:

[0016] 1) Take straw board sanding powder accounting for 84% of the total weight and dry until the moisture content is 5%;

[0017] 2) Add the dried straw board sanding powder and 1% of the total weight of auxiliary materials into a high-speed mixer and stir evenly; the release agent in the auxiliary materials accounts for 10% of the weight of the auxiliary materials; the pigment accounts for 90% of the weight of the auxiliary materials.

[0018] 3) At the same time, take 15% of the total weight of the adhesive (modified urea-formaldehyde resin adhesive model NL-UF07) and 1% of the total weight of the adhesive, and stir evenly; then add 3% of the adhesive by weight. The pH value is adjusted to 4.5; starch in the auxiliary agent: soybean powder=1: 1.5.

[0023] Example 2, using straw board sanding powder as the main raw material, the weight of the finished flowerpot is 500g, and the specific manufacturing process steps are as follows:

[0024] 1) Take straw board sanding powder accounting for 50% of the total weight and dry until the moisture content is 4%;

[0025] 2) Add the dried straw board sanding powder and auxiliary materials accounting for 20% of the total weight into a high-speed mixer and stir evenly; the release agent in the auxiliary materials accounts for 20% of the auxiliary material weight; the pigment accounts for 30% of the auxiliary material weight, and the dye accounts for 50% by weight.

[0026] 3) At the same time, take 40% of the adhesive (modified urea-formaldehyde resin adhesive model NL-UF07) and 15% of the total weight of the adhesive and stir evenly; then add 3% of the adhesive by weight. The pH value of the mixture is adjusted to 6; the starch in the auxiliary agent: soybean powder=1:0.5.

Abstract

The present invention relates to a method of producing a flowerpot with the sanding powder of a waste straw board. In the technique, the sanding powder of the waste straw board is dried; the dried sanding powder of the waste straw board is uniformly mixed with auxiliary materials in a high-speed mixer; meanwhile, adhesive is uniformly mixed with addition agent; composite hardener is added, so thatthe pH value of the adhesive solution is regulated to 4.5 to 6.0; the adhesive solution is sprayed into and then uniformly mixed with the mixed material; the material is dried; finally, compression molding is carried out. The present invention has the advantages that because raw materials, such as soil, plastic, timber or other plant fibres, are replaced by the sanding powder for the production of flowerpots, the flowerpots are cheap and high-quality, the waste is turned into treasure, resources are saved, and the drainage and air permeability of the flowerpots is good. In the process of transplanting, the flowerpot does not need to be turned over, and the nutritious flowerpot in the soil can be naturally degraded into humic acid organic fertilizer. If freely falling down to the cement floor from an altitude of one meter, the flowerpot cannot be damaged. After being irradiated by an xenon lamp for total sixty six hours, the appearance and shape of the flowerpot are greatly changed, the mildewing phenomenon is severe, the surface goes rough and has a few of cracks, so the phenomena indicate that the flowerpot has the properties of controllable photodegradation and biological degradation, and therefore the flowerpot is degradable.

Description

technical field [0001] The invention relates to waste straw board sanding powder as the main raw material, adding a small amount of auxiliary materials such as mold release agent, pigment, dye, etc., applying adhesive and appropriate additives, and making waste through high-speed stirring, drying, molding, etc. Straw board sanding powder planter. It belongs to the technical field of flower pot container manufacturing. Background technique [0002] At present, there are all kinds of flowerpots on the flower market: wooden flowerpots, clay flowerpots, porcelain flowerpots, plastic flowerpots... The domestic market mainly uses two types of flowerpots made of clay and plastic, Seedling pots; foreign countries mainly use degradable plastic and paper flower pots and seedling pots. The performance characteristics of various flowerpots are also quite different. Clay flowerpots: Compared with plain-fired flowerpots and plastic flowerpots, it not only destroys a lot of land and tak...
