Performance test
Detection method/test method
New plant pot materials were prepared according to the preparation methods of examples 1 to 13 and comparative examples 1 to 4, and the prepared plant pots were examined as follows, and the examination results are shown in Table 3.
Tensile strength: detecting according to a method in GB1040-79 Plastic tensile test method;
flexural strength and flexural modulus: detection was carried out according to the method of GB 1042-79.
TABLE 3 test results of examples 1 to 13 and comparative examples 1 to 4
As can be seen from the test data of examples 1 to 13, comparative examples 1 to 4, and Table 3, the new flowerpot material prepared by the present application has a tensile strength of more than 29.5MPa, a bending strength of more than 28.8MPa, and a bending modulus of more than 843MPa, which indicates that the new flowerpot material has uniform filler distribution, good compatibility between the filler particles and the raw materials such as PP, ABS, etc., and does not cause a situation that various properties of the new flowerpot material are greatly reduced due to agglomeration of the filler particles in the material.
From the test data of example 2 and examples 4-5, it can be seen that the modified filler prepared in preparation example 2 has better compatibility with PP and ABS raw materials, and in combination with examples 6-8, the tensile strength, flexural strength and flexural modulus of the new flowerpot material are gradually reduced with the increase of the modified filler, therefore, the amount of the modified filler is not recommended to be more than 45 kg.
Since alkylphenol ethoxylates has a good permeation effect, after the alkylphenol ethoxylates is applied to a hydrophobic agent, the permeation effect of the hydrophobic agent can be increased, the hydrophobic agent is enabled to be in better contact with the surface of a filler, a hydrophobic film formed on the surface of filler particles is enabled to be more compact, and the compatibility between the filler particles and PP and ABS is increased, so that the detection data of the embodiment 7 and the embodiments 9-10 show that the alkylphenol ethoxylates is added to the hydrophobic agent in the preparation process of the modified filler, and various performances of the novel flowerpot material can be improved.
From example 11, it is clear that a larger particle size of the filler is not favorable for uniform dispersion in the new material, and therefore, the average particle size is not preferably more than 1.5 mm.
From the detection data of the examples 12 to 13, it can be known that the modified filler can be better added into new flowerpot materials when the filler is straw or stone powder.
As can be seen from the detection data of example 8 and comparative example 1, when the filler is not modified, the filler has poor compatibility with other raw materials, so that the filler is easy to agglomerate in the new material, and the new material has poor performance; in combination with the filler which is not treated by the wetting agent in the comparative example 2, the surface tension between the surface of the filler particles and the hydrophobic agent is larger, so that the hydrophobic agent is not easy to form a film on the surface of the filler particles; in combination with comparative examples 3-4, when the water repellent agent is not added with polyisocyanate emulsion or sodium polyacrylate, the film forming property of the surface of the filler particles is poor; when the hydrophobic film on the particle surface is poor, the compatibility of the filler and other raw materials of the new material is greatly influenced, and various properties of the new material are greatly reduced.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of the present application is not limited by the embodiments of the present application, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
