- HDPE polyethylene
- B of polyethylene can be in particularly problematic areas as an alternative or in addition to Application come.
- Polyethylene either as an additional coating on top of one already existing polymer coating applied or instead of the original used to process polymer.
- HDPE is particularly against Bio-Diesel (rapeseed oil methyl ester) resistant.
- a wear layer on the Polymer layer applied, for example by the fact that wear-resistant Substances as particles on the not yet hardened fiber-reinforced Polymer layer can be sprinkled on.
- a separate wear protection layer can, for example, be a cross-linkable one Polyester or moisture-curing polyurethane are used as binders which the wear-resistant substances are present.
- To be able to discharge metal is additionally guaranteed in the wear layer and / or carbon in an amount of up to 20 wt .-% introduced. Silicon carbide or iron oxides as wear-reducing materials the advantage that they improve the discharge capacity at the same time.
- Coke or graphite can be used as carbon.
- the wear layer ie the layer containing the wear material
- a cover layer as a seal
- a layer of a self-curing polyurethane in an amount of 100 to 300 g / m 2 .
- This layer can then also ensure the conductivity by adding carbon.
- the fiber material is preferably in the form of a nonwoven, with a basis weight of 100 to 500 g / m 2 .
- Polyester and glass fiber fleeces are preferred; other materials can also be used.
- adhesion or elastic properties intermediate layers may be appropriate.
- a fuel-resistant sealing compound to be sealed. It can be both around a parting line, as well as around Joints to adjacent road surfaces and to joints to built-in parts act.
- the sealing compound is expediently a two-component reactive curing sealant, especially based on polysulfide or polyurethane.
- the method according to the invention is suitable for existing ones Build over joints without causing leaks.
- the elasticity of the Plastic masses and the fiber material are sufficient (tension) tensions catch.
- the method according to the invention for creating a fuel-resistant has the advantage that Lifting and adjusting built-in parts by applying a further ceiling no longer have the necessary protection height, if necessary, milling an existing road surface by a maximum the thickness of the new layer to be applied is eliminated.
- the total layer thickness are generally 2 to 9 mm, in particular 3 to 5 mm.
- Covering layer As far as the thickness of the coating is not important or a stronger one Covering layer can be accepted, it is easily possible to get one Provide cover layer from an alternative cover material.
- alternative Materials are conventional building materials, such as bitumen, Asphalt, sand, gravel, cladding, concrete and the like. In this case it is sealing level not visible.
- the method according to the invention can be applied to existing road surfaces various designs can be used, provided they are pre-cleaned Show underground. These include, for example, paving slabs, bituminous ceilings and especially concrete ceilings. For concrete blocks and -covering is recommended to use a polyurethane primer if for the central plastic layer a polyester is used.
- the optimal installation thickness of the multi-layer system is around 3 to 6 mm. To generate a uniform road surface, local lower or larger layer thicknesses are readily accepted become.
- the method according to the invention primarily serves to seal existing non-liquid-tight concrete, paving or pavements Rolled asphalt. However, it can also be used to renovate existing ones liquid-tight road surfaces that have become in need of repair, be used.
