Problems solved by technology

[0004] Plastic nutrition bowls have the following disadvantages: 1) pollute the environment, cannot be degraded or incompletely degraded; 2) have poor air permeability; 3) are insoluble in water; 4) cannot provide nutrients by themselves, and need to rely on external compensation; 5) made of starch The cost of degradable plastics is relatively high

Abstract

The invention provides a biodegradable composite material, a plant nutrient pot and a production method of the plant nutrient pot, and relates to the technical field of degradable materials. The biodegradable composite material is prepared from the following raw materials in parts by weight: 20 to 40 parts of degradable plastic and 55 to 80 parts of straw powder. The biodegradable composite material has the advantages of being capable of being completely degraded, and being environment-friendly, pollution-free, good in ventilation and low in cost. The plant nutrient pot produced by using the biodegradable composite material has the advantages of environment friendliness, no pollution, good drainage ventilation, resource saving, low cost and capability of generating nutrient substances required by nursery stock after degradation.

Description

technical field [0001] The invention relates to the field of degradable materials, in particular to a degradable composite material, a plant nutrition bowl and a preparation method thereof. Background technique [0002] Oxidative biodegradation technology is a new hotspot in the development of environmentally friendly materials in the world. It is one of the most advanced technologies after starch biodegradable plastics. It has not been understood and used by most people in China. Oxo-degradable plastic refers to a completely degradable environmentally friendly plastic that undergoes both oxidative degradation and biodegradation during the degradation process. By adding degradation additives to polymer materials (PE, PP and PS), the plastics undergo oxidation reactions under the action of light or / and heat. After the plastic products are abandoned, there are two kinds of substances in the additives: one is the pre-oxidant (mainly some non-toxic metal ions), and the other is...
