Foamed hollow plastic fender product and production method

Abstract

The invention provides a foamed hollow plastic fender product and a production method and equipment. The product comprises outer skin of the fender body and a filling layer, and is characterized in that a center hole is arranged in the fender body; an outer layer of an inner core, an enhancement layer and an inner layer of the inner core are sequentially arranged between the filling layer and thecenter hole, and a high-strength extrusion-tension rod is arranged in the filling layer. The invention has the following advantages: the product is suitable for the quay fenders, crash barriers, girders, columns and other building structures, saves the timber, rubbers and steel, is easy for construction, shortens the construction period and saves the building cost; besides, the product has excellent chemical stability and oxidation resistance, substantially enhances the impact resistance and flexibility, increases the elastic modulus and rigidity, thoroughly solves the problem that the steel reinforced concrete is corroded by seawater and doubles the service life; the application range of the product is expanded and waste polyethylene is used as the main material, thus obviously lightening the pressure of pollution.

Description

technical field [0001] The invention belongs to an anti-collision fender used on the shore and a pile product used on land, in particular to a foamed hollow plastic fender product and a production method. Background technique [0002] When building the wharf, stone, cement, and mountain soil are often used to fill in the sea to form a "mountain" shaped trestle bridge to form a slipway. The coastline of seawater is divided artificially, the seawater does not flow, destroys the original ocean current, seriously affects and destroys the ecological environment of the coastline, causes the seawater in the wharf to deteriorate and stink, and damages the living environment of marine organisms, and the working hours are long and the cost is high. When soiling, it destroys the ecology of the land. At present, old-style plastic fenders are used, such as the "low-foaming plastic fender" with patent No. 02281015.3. Because the inner core is made of high-density polyvinyl foam material,...

AI Technical Summary

Problems solved by technology

The coastline of seawater is divided artificially, the seawater does not flow, destroys the original ocean current, seriously affects and destroys the ecological environment of the coastline, causes the seawater in the wharf to deteriorate and stink, and damages the living environment of marine organisms, and the working hours are long and the cost is high. When soiling, it destroys the ecology of the land

At present, old-style plastic fenders are used, such as the "low-foaming plastic fender" with patent No. 02281015.3. Because the inner core is made of high-density polyvinyl foam material, it is relatively brittle and easy to break when subjected to a large impact; and Heavy weight, not easy to float; low rigidity, easy to bend when making piles

The joints are not easy to handle when beams and columns are connected, so solid products are only suitable for use as fenders, not suitable for use as building piles
