Effect test

Embodiment 1

[0036] The screening experiment of embodiment 1 epoxy resin

[0037] Experiment A (the scheme is oyster shell powder + water)

[0038] Mix 33.4 parts of oyster shell powder and 66.6 parts of water, stir evenly at room temperature, let stand for 4 days, solidify and form the finished product of oyster shell powder material.

[0039] Test results: As the oyster shell powder itself has no cohesive force, the final oyster shell powder material is very brittle, and it will become powder when pinched hard, and the hardness does not meet the expected standard. This program cannot be used.

[0040] Experiment B (the scheme is oyster shell powder + water + white cement)

[0041] Mix 40 parts of oyster shell powder with 20 parts of water, add 40 parts of white cement, stir evenly at room temperature, let stand for 4 days, solidify and form the finished product of oyster shell powder material.

[0042] Test results: Since the oyster shell powder and white cement itself have no cohesiv...

Embodiment 2

[0058] Embodiment 2 (screening of epoxy resin and curing agent ratio)

[0059] (1) At room temperature, mix oyster shell powder and epoxy resin to obtain a uniform mixture;

[0060] (2) Add the curing agent to the mixture obtained in the step (1), and stir at room temperature to obtain a uniform semi-finished product;

[0061] (3) Pour the semi-finished product obtained in the step (2) into a silicone mold with a length of 100 mm, a width of 50 mm and a height of 20 mm, so that the height of the mixed material is limited to 4 mm;

[0062] (4) Stand still until solidified and formed, and obtain an oyster shell powder biomass composite material with a length of 100 mm, a width of 50 mm, and a height of 4 mm.

[0063] According to the experimental procedure of Example 2 and the ratio of each group of oyster shell powder, epoxy resin and curing agent in Table 1, 5 groups of materials are weighed respectively, and the total weight of each group of materials is 100g, and the oyster...

Embodiment 3

[0071] Example 3 Validation of the effect of accelerator

[0072] (1) At room temperature, mix oyster shell powder and epoxy resin to obtain a uniform mixture;

[0073] (2) Add curing agent and accelerator to the mixture obtained in step (1), and stir at room temperature to obtain a uniform semi-finished product;

[0074] (3) Stand still until solidified and formed to obtain the oyster shell powder biomass composite material.

[0075] Table 2: Validation of Accelerator Action

[0076]

[0077] The performance and curing time of the biomass composite materials in groups 1-4 in Table 2 of Example 3 were verified, and it was found that the effect of the accelerator was negligible, so the accelerator could be added or not.

Abstract

The invention discloses an oyster shell powder composite material and a preparation method thereof. The oyster shell powder composite material excellent in industrial processing performance and moderate in hardness and ductility can be prepared into different industrial products including modern furniture, home decorations and stationary and substitute for some plastics, timbers and cement. Compared with the prior art, the oyster shell powder composite material has the advantages that oyster shell powder accounts for at least 50% of the composite material and can ease the redundancy of oystershells after the oyster shell powder composite material is popularized and utilized on a large scale.

Description

technical field [0001] The invention belongs to the technical field of polymer / biomass composite material and its preparation, and in particular relates to an oyster shell powder biomass composite material and a preparation method thereof. Background technique [0002] Oyster, referred to as oyster, is a worldwide shellfish that ranks first in the artificially cultured shellfish in the coastal areas of China. In recent years, people's consumption of oysters has continued to increase, and the scale of oyster farming has continued to expand, but oyster shells have been discarded as waste, and a large number of oyster shells have caused serious pollution to the environment. [0003] The use of oyster shells has existed since ancient times. For example, the building of oyster shell walls is a living specimen of the regeneration and application of ecological technology by residents in the coastal areas of Lingnan, but this use has been gradually replaced by new materials. [000...
