Description

Self-illuminating floating fenders

technical field

The utility model relates to marine equipment, in particular to a floating fender device.

Background technique

The existing floating fenders are mostly made of rubber, which can play a protective role under normal berthing conditions, but at night, when the light is poor, it is difficult to berth and easily cause accidents.

At present, luminescent products are in the ascendant, and various new luminescent pigments have emerged in endlessly. For example, powdery photoluminescent light-storing luminescent materials can realize light-emitting function by absorbing various visible light, especially have a strong absorption ability for short-wave visible light below 450 nanometers, and can be recycled many times. This luminescent pigment does not contain radioactive elements, and can be used as an additive to be evenly distributed in various transparent media, such as paint, powder coating, ink, paint, enamel, ceramics, plastic, fiber, glass, etc. It presents its own appearance color, and emits different colors of light in dark places, showing good functions of low-level emergency lighting, indicating signs, and decoration and beautification. Most of the luminescent pigments are slightly soluble in water and decompose in acid, so they cannot be applied to water-soluble systems and acidic systems.

On the other hand, spraying polyurea elastomer (Spray Polyurea Elastomer, hereinafter referred to as SPUA) technology is a foreign country in the past ten years, after high solid content coatings, water-based coatings, radiation curing coatings, powder coatings and other low (no) pollution coating , a new type of solvent-free and pollution-free green construction technology developed to meet the needs of environmental protection. It is developed on the basis of reaction injection molding (RIM) technology. This process belongs to the rapid response spraying system and the raw material system It does not contain solvents, has fast curing speed and simple process. It can be easily sprayed on the facade and curved surface with a thickness of more than ten millimeters without sagging. SPUA technology has completely broken through the limitations of traditional environmental protection coating technology. Therefore, once this technology comes out, it will develop rapidly.

Polyurea elastomer is a two-component, 100% solid content, does not contain any volatile organic compounds, and is environmentally friendly. The material itself is a light yellow translucent liquid, which can be completely mixed with luminous pigments to effectively ensure the luminous effect. And through the special dispersant and anti-sedimentation agent, it can fully ensure the uniform distribution in the polyurea elastomer. It does not contain catalysts and is fast curing. It can be sprayed on any curved surface, inclined surface and vertical surface without sagging. It gels in 5 seconds and reaches walking strength in 1 minute.

The thickness of the SPUA technology in one construction can range from hundreds of microns to several centimeters, which overcomes the disadvantages of multiple constructions in the past. Using a complete set of equipment, the construction is convenient and the efficiency is extremely high; the design thickness requirement can be achieved in one construction, which overcomes the disadvantages of the previous multi-layer construction. SPUA technology has good prototype reproducibility, continuous and dense coating, no seams, no pinholes, beautiful and practical.

The resulting polyurea elastic layer has excellent physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, and corrosion resistance.

Contents of the invention

In view of the above-mentioned problems existing in the prior art and the development status of the prior art, the utility model aims to disclose a self-luminous floating fender device, which uses polyurea elastomer instead of rubber, and the outermost polyurea layer Luminous pigments are added to the foam, and sprayed polyurea elastomer technology (SPUA) is used to spray on the outer layer of the lightweight foam, thus possessing self-luminous performance.

The technical solution of the present utility model is realized in this way:

A self-illuminating floating fender device, comprising a core, a lightweight foam, characterized in that it also includes a polyurea elastic layer and a polyurea luminous layer; the lightweight foam is bonded to the outer surface of the core; the polyurea The elastic body is sprayed and attached to the surface of the lightweight foam to form a polyurea elastic layer; the polyurea luminescent layer is sprayed and attached to the outer surface of the polyurea elastic layer, and forms a whole with the polyurea elastic layer. The polyurea light-emitting layer is formed by uniformly distributing the light-emitting material in the polyurea elastic body material, spraying and adhering to the outer surface of the polyurea elastic layer.

The luminescent material is a powder photoluminescence luminescent material. For example, an R-type luminescent pigment whose luminescent color is orange-red can be selected.

Compared with the prior art, the beneficial effects of the utility model are obvious:

The polyurea elastomer material makes the performance of the floating fender more excellent, improves the floating height, reduces the reaction force, improves corrosion resistance, aging resistance, and prolongs the service life. The addition of luminescent pigments can make the original color monotonous floating The fenders turn into various colors, bright and beautiful, especially at night, which brings convenience to ships berthing, makes night operations safe, reliable, high accuracy, and can effectively avoid accidents and reduce losses.
