Method for controlling biodegradation induction period of biodegradable high polymer material
The technical field is as follows:
the invention relates to the biodegradation performance and control of biodegradable polymer materials and products, in particular to a method for controlling the biodegradation induction period of biodegradable polymer materials.
Background art:
at present, the plastic waste is large in quantity and difficult to degrade, and the environment and the ecology are seriously influenced. Therefore, the application of biodegradable polymer materials is increasing. Due to the fact that the controllability of the biodegradability of the biodegradable high polymer material and the biodegradable high polymer product is not ideal, particularly the volatility of the biodegradation induction period is large, the requirements of storage time and storage environment of the biodegradable high polymer material and the biodegradable high polymer product are higher than those of common plastics, and popularization and use of the biodegradable high polymer material and the biodegradable high polymer product are greatly influenced.
The invention content is as follows:
the invention provides a method for controlling the biodegradation induction period of a biodegradable high polymer material, which improves the biodegradation induction period of the biodegradable high polymer material and a product by adding a master batch containing a control agent or directly adding the control agent, and achieves the purpose of prolonging the controllability of the biodegradation induction period by adjusting the technology of the control agent; meanwhile, the ecological friendly and environmental protection level of the biodegradable high polymer material and the product is not influenced.
The control agent is calcium oxide (CaO), the calcium oxide (CaO) is added in proportion, and the content proportion in the final end product of the biodegradable polymer material is 0-60%.
The control agent is calcium oxide (CaO); 0 to 85 percent of biodegradable high polymer material, 0 to 99.5 percent of calcium oxide (CaO) and a small amount of other additives are uniformly mixed to prepare control agent master batch; then the master batch of the control agent is uniformly mixed with the biodegradable high polymer material to process and manufacture the biodegradable high polymer material and the product, so that the biodegradation induction period of the biodegradable high polymer material and the product is improved and the controllability is prolonged; and ensures good performance. This is a master batch method.
The control agent is calcium oxide (CaO); 2 to 100 percent of biodegradable polymer material, 0 to 60 percent of calcium oxide (CaO) and a small amount of other additives are uniformly mixed and added into production and processing equipment to process and manufacture the biodegradable polymer material and the product, so that the biodegradation induction period of the biodegradable polymer material and the product is improved and the controllability is prolonged; and ensures good performance. This is a straightforward approach.
Compared with the prior art, the method provided by the invention can achieve the following technical effects:
1. the biodegradation induction period of the biodegradable high polymer material and the product is improved and the controllability is prolonged; meanwhile, the ecological friendly and environmental protection level of the biodegradable high polymer material and the product is not influenced.
2. The storage condition of the biodegradable polymer material and the product is widened and the storage cost is reduced.
3. When the biodegradable high polymer material and the product are used, the biodegradation induction period can be scientifically controlled.
