Embodiment 1

[0026] A production method utilizing enteromorpha to prepare thermal insulation materials, comprising the steps of:

[0027] (1) Enteromorpha pretreatment

[0028] Use the Enteromorpha fishing device to catch fresh Enteromorpha, wash and remove impurities such as sediment, then dry and crush;

[0029] (2) Enteromorpha antiseptic treatment

[0030] The Enteromorpha obtained in step (1) is immersed in a dehydroacetic acid solution with a mass fraction of 0.05% for 10 min;

[0031] (3) Water-repellent and oil-repellent treatment on the surface of Enteromorpha

[0032] Add a silicone-based water and oil repellent treatment agent to the antiseptic treatment solution in step (2), and continue soaking for 1 hour;

[0033] (4) Enteromorpha drying treatment

[0034] After the Enteromorpha treated in the step (3) is cleaned with clear water for 2 times, vacuum filtration is performed to obtain modified Enteromorpha;

Abstract

The invention discloses a production method for preparing a thermal insulation material by using enteromorpha. The method comprises the following steps: (1) pretreatment of enteromorpha; (2) preservative treatment; (3) oil and water-repellent treatment for the surface of the enteromorpha; (4) drying treatment of the enteromorpha; (5) preparation of materials; (6) molding. The method can effectively solve the problem of enteromorpha treatment, save resources, realize utilization of waste products, and protect environment; the enteromorpha has the advantages of high yield, easy availability and low cost, compared with the traditional insulation materials which do not have flame retardation performance and needs addition of fire retardants in the preparation process, the enteromorpha has flame resistance; after the preservative treatment as well as the oil and water-repellent treatment, the enteromorpha can be used for preparing the thermal insulation material with good anticorrosion, flame retardation, and thermal insulation effects, and the thermal insulation material can be used in places where insulation treatment is needed, such as pipeline insulation, wall insulation, and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a production method for preparing thermal insulation materials using enteromorpha. Background technique [0002] Enteromorpha is a kind of green algae. The algae are bright green and consist of a single layer of cells, which are surrounded by tubes or adhered into ribbons. Under the microscope, there are often many air sacs in the algae of Enteromorpha. Enteromorpha is widely distributed in the world. In the oceans, some are distributed in brackish water or rivers. Due to global climate change, eutrophication of water bodies and other reasons, the "green tide" of large marine alga Enteromorpha will break out, and it needs to be salvaged and removed. Since 2008, it has periodically erupted and disappeared in the Yellow Sea from May to August every year, causing different environmental impacts and economic losses to coastal areas. [0003] The larg...
