Embodiment 1

[0027] see Figure 1-4 , the present invention provides the following technical solutions: a seaweed masterbatch, wherein the ingredients and percentages of the seaweed masterbatch are: seaweed powder: 60-80%, EVA: 10-15%, zinc stearate: 3-5% , Aluminate: 1.5-2.5%, binder: 0.5-1%, antioxidant: 1-2%.

[0028] The seaweed powder is washed and desalted seaweed, and the seaweed is dehydrated and dried and crushed. The crushed seaweed powder is less than 300 mesh. minute.

[0029] The percentage content of each component of the seaweed masterbatch is: seaweed powder 60%, EVA 31%, zinc stearate 5%, aluminate 2.5%, binder 0.5%, antioxidant 1%.

Embodiment 2

[0031] In this embodiment: the percentage content of each component of seaweed masterbatch is: seaweed powder 65%, EVA 26%, zinc stearate 5%, aluminate 2.5%, binder 0.5%, antioxidant 1%.

Embodiment 3

[0033] In this embodiment: the percentage content of each component of seaweed masterbatch is: seaweed powder 70%, EVA 21%, zinc stearate 4.7%, aluminate 2%, binder 0.8%, antioxidant 1.5%.

Abstract

The invention provides a seaweed master batch and a manufacturing method of EVA foam, wherein EVA foam comprises the seaweed master batch; the seaweed master batch comprises the components in percentage: 60-80% of seaweed powder, 10-15% of EVA, 3-5% of zinc stearate, 1.5-2.5% of aluminate, 0.5-1% of an adhesive and 1-2% of an antioxidant. Multiple raw materials are combined with the seaweed powder to prepare the seaweed master batch, the seaweed master batch is used, and a sole can effectively remove TVOC, peculiar smell, staphylococcus aureus and the like; in addition, EVA is biodegradable, similar to PVC in price, light in weight, free of odor, heavy metal and phthalate, high in transparency, soft, high in toughness and ultra-strong in low temperature resistance (-70 DEG C); and in addition, the EVA is also resistant to water, salt and other substances, also has high heat adhesion and low adhesion temperature, can be used for silk-screen printing and offset printing, and has remarkable significance when being applied to the shoe manufacturing industry.

Description

technical field [0001] The invention belongs to the technical field of seaweed processing, and in particular relates to a preparation method of seaweed masterbatch and EVA foam. Background technique [0002] The habitat of seaweed is the ocean. When the ocean water body is affected, a large number of seaweeds grow abnormally, which poses a threat to marine ecology and affects human survival. In the Caribbean Gulf of Mexico, sargassum is scattered throughout the Caribbean Gulf, which is harmful to coastal ecology. Wreaking havoc, in some areas the seaweed completely covered the beach, making it impossible for the turtles to lay their eggs. A study shows that seaweed on the beach is a threat to human health or causes disease. When the seaweed decays, it consumes more oxygen, forming a special low-oxygen zone, which means that other seaweeds such as corals, fish, etc. May die from lack of oxygen. [0003] The derivation of a large number of seaweeds has deteriorated the local...
