Definitions

  • the invention relates to covers that are placed on internal combustion engines.
  • the invention especially relates to the engine top cover that consists of a mixture of polyol, isocyanate, blowing agent, cell expander, water, liquid pigment concentrate and in-mold coating.
  • Covers that are made of various materials and that possess various functionalities are used in a variety of vehicle engines in the prior art.
  • the invention is an engine side cover which contains a cover made of metal plate and a cork gasket; wherein it relates to containing the mentioned cover made of aluminum, a cover canal provided on the sides of the inner part of the mentioned cover, O-ring placed in the mentioned canal of the cover, filter that is placed on the inner part of the mentioned cover and a ventilation pipe placed on the outer part of the mentioned cover.”
  • the object of the mentioned invention is to provide a high-strength and oil-proof engine side cover, which is made of aluminum, in order to prevent the engine from leaking oil, on the side of the engine.
  • a Cover Another application is the utility model application no. TR200700730 called "A Cover”.
  • the invention is briefly described as: "The present invention relates to a cover, which is placed on the floor of vehicles such as buses, midibuses, minibuses; which is used for accessing the engine and which is assembled by means of t-nuts”.
  • the object of the mentioned invention is to provide a cover, which is located on the floor of the vehicle for accessing the engine and which does not have any exposed apparatus that may disturb people such as clamping arms and connection bolts.
  • Another application is the utility model application no. TR201004537 called “A novelty in engine top covers of tractors'.
  • the invention is briefly described as: "The present invention relates to engine top covers (valve cover) that are placed on tractor engines.
  • the engine top cover of the invention is characterized in that; it is made of aluminum, wherein it contains o- ring gasket housing (2.a) and o-ring gasket as the seal (leak tightness) inside the o-ring gasket housing (2. a).
  • the object of the mentioned invention is to produce an engine top cover made of aluminum and to use o-ring gasket in the structure, due to the indurable and fragile structure of engine covers, used in the prior art, that essentially contain plastics.
  • Present invention relates to an engine top cover that meets the abovementioned requirements, eliminates all disadvantages and provides some additional advantages.
  • Primary object of the invention is to provide a cover that consists of a mixture of polyol, isocyanate, blowing agent, cell expander, and water, wherein it is singly placed on internal combustion engines.
  • Another object of the invention is to provide temperature resistance for temperatures between -40°C and 140°C.
  • Another similar object of the invention is to provide a lightweight cover as compared to similar ones in the prior art.
  • Another object of the invention is to provide a water based integral type system, wherein it is different than foam type polyurethanes.
  • Another object of the invention is to resist high temperatures (140°C) and not get deformed.
  • the invention is a cover that consists of a mixture of polyol, isocyanate, blowing agent, cell expander, water, liquid pigment concentrate and in-mold coating, wherein it is to be placed on internal combustion engines.
  • Raw material Preferred amount (%) Usable amount (%)
  • Polyol is a mixture, which contains nonhazardous additives and consists of a mixture of ⁇ , ⁇ , ⁇ ', ⁇ ', ⁇ ""- Pentamethylene triamine, 2,2'-iminodiethanol of specified materials, with an OH number between 150-180 and water ratio of maximum 1 %. It is water based MDI type polyether polyol. Various catalysts, surfactants, crosslinking agents, filling materials, antistatic materials and such may be used in polyol.
  • Isocyanate is an MDI type isocyanide with NCO value between 26-29. It consists of a mixture of 4-4'-methylenediphenyldiisocyanate; diphenylmethane / 4,4' diisocyanate(MDI)polymethilenepolyphenylpolyisocyanate, glycerol etoxylated-propoxylated, coploymer and o-(p-isocyanatebenzyl)phenyl isocyanate,diphenylmethane-2,4'diisocyanate.
  • Polyurethane foams or polyurethane based products consist of two main components, catalysts that start a reaction for them and blowing (foaming) agents.
  • the two main components are: 1 st Component (Component A): Polyol; 2 nd Component (Component B): Isocyanate.
  • Blowing agent lowers the density. It increases skin thickness. It increases the effect of sound absorption. Sound absorption has two types; internal and external. Inflator gas; is used for improving external sound absorption. This gas aids the product in moving inside the mould and filling the mould.
  • Cell expander is a mixture of glycerol, propylene oxide, ethylene oxide polymer. It expands the pore structure and aids in absorbing of the sound in the material. Cell expander is used to improve internal sound absorption.
  • the invention also involves the use of liquid pigment concentrate and in-mold coating.
  • Liquid pigment concentrate is used to match the color of polyol with the on-mold coating and to prevent color differences in deburring processes with deep burrs.
  • On-mold coating is used to remove the scars of raw material formed when moving inside the mould.
  • Pressure values of the polyurethane machine are: 150 ⁇ 50 bar for polyol and 170 ⁇ 70 bar for isocyanate. These pressure values may differ according to temperature, viscosity and nozzle diameter. Raw material temperatures (in the range of 20-35 ⁇ in raw material tanks) and mold temperatures are adjusted according to parameter conditions (40-60 ⁇ ). Mixing ratio of raw materials (polyol/iso) in the PU (polyurethane) machine may vary between 100/45 and 100/62 depending on the desired material hardness. Application of the mentioned composition on the cover:
  • on-mold coating is made ready.
  • mould release agent is added to the mould so as to enable easy removing of the material from the mould.
  • on-mold coating is added under a certain temperature.
  • the composition mixed inside the PU machine is injected into the mould from the material input area of the mould or casting process is achieved in the form of the cast (by pouring into the mould from the head of the PU machine with a certain path when the mould is open).
  • the product is removed from the mould. After minimum 8 hours on settling racks, products are deburred by burr removing operators. Product is packaged and moved to stock.
  • Mentioned on-mold coating preferably has a ratio of 3-6%.
