Problems solved by technology
Although this kind of anti-adhesion film plays a certain role in marine antifouling, because the template of its protruding structure is processed by etching method, there are disadvantages such as complicated process and high cost, and it is still difficult to produce after it is made of silicon polymer material. There are disadvantages such as heavy film weight and easy aging of polymers, so the use and maintenance costs are relatively high

Embodiment Construction
[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.
[0031] refer to figure 1 , the preparation method of diatomite solidified surface, comprises the steps:
[0032] In the first step, the diatomite is pretreated to obtain a diatomite mixture. The diatomite pretreatment process can adopt common pretreatment methods, and can also adopt the following diatomite pretreatment steps: (A) at room temperature, diatomite is dissolved in HF solution with a mass percentage concentration of 1.5% to 3.5%. Soaking for 3 minutes to 5 minutes, and then filtering with a filter cloth of 15 μm to 45 μm to obtain the first diatomite mixture. (B) Soak the first diatomite mixture in NH4, H2O2, H2O mixture (1:2:7) for 10min~20min at a temperature of 80℃~90℃, and then use a 15μm~45μm filter Cloth was filtered to obtain the...

Abstract
The invention relates to the field of bionic technology, specifically to a diatomite solidification method and an application thereof. The manufacturing method of the diatomite solidified surface comprises the following steps of: 1) diatomite pretreatment; 2) diatomite acid etching treatment; and 3) diatomite thermocompression bonding solidification to obtain the diatomite solidified surface. Thediatomite solidified surface is arranged on the liquid-contacting surface of an object which is immersed in a liquid, and the diatomite solidified surface forms an antifouling surface on the liquid-contacting surface so as to prevent adhesion of marine fouling organisms. By the adoption of the above technical scheme, the diatomite solidified surface prepared by the above technology can reserve a lot of micrometer or nanometer protruding thorn structures and has characteristics of stable chemical properties, light weight, wear resistance, certain strength and the like. The diatomite solidifiedsurface prepared by the above technology can be applied in antifouling surface, thus effectively reducing adhesion of marine fouling organisms.
Description
technical field [0001] The invention relates to the field of bionic technology, in particular to a curing method and application of diatomite. Background technique [0002] Diatomaceous earth is a siliceous sedimentary rock formed from the ancient remains of diatoms. It is mainly composed of siliceous skeleton fragments of ancient diatoms, and its main chemical component is silicon dioxide. Diatomaceous earth exists as a mineral in large quantities in nature, so it has a wide range of sources and low prices. Because diatomite has the characteristics of fineness, light weight, large porosity, stable chemical properties, wear resistance, heat resistance, and certain strength, it is a material with important application value. Existing diatomaceous earth is commonly used in filtration, insulation, and sound-absorbing material applications. [0003] Marine microorganisms, algae, and shellfish often attach and grow on the surface of underwater vehicles and underwater operating ...
