Abstract

Description

    POLYMER COMPOSITE
  • The present invention relates to recycled polymer composites, to the production method thereof and the use thereof in white goods.
  • Microfibers in textiles which are called lint and which are invisible to the naked eye pose great risks to all living beings, in particular humans. Releasing of said microfibers into the environment, in particular to the seas and oceans, and constant accumulation thereof results in toxic affects in the food chain.
  • In the state of the art American Patent No. US 6,756,412 B2, thermoplastic composites with improved mechanical properties with the use of fibers and a method for producing said composites are disclosed. Recycled plastic is used for the production of the composites.
  • The state of the art American Patent Application No. US 5,545,475 A relates to a method for production porous composite film by using liquid crystal polymer fibers as microfiber reinforcement in order to improve the poor dimensional stability and very high coefficient of thermal expansion of polytetrafluoroethylene which is widely preferred to be used especially in electronic applications.
  • The aim of the present invention is the realization of white goods comprising plastic composites obtained by recycling the microfibers (lints) accumulated on the filters of the white goods and adding the same into thermoplastic materials.
  • The polymer composite realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises at least one thermoplastic material; recycled waste microfiber; maleic anhydride–grafted polypropylene (MA-g-PP) compatibilizer; at least one antioxidant; at least one lubricant; at least one color masterbatch and as per preference, a mineral reinforcement such as talk, calcite, etc. and/or a fibrous reinforcement such as glassfiber, carbon fiber, etc.
  • The polymer composite of the present invention can be used in white goods such as laundry washing machine, laundry drying machine, dishwasher, refrigerator, air conditioner, oven, hair dryer, coffee machine, tea machine, curling iron, hair straightener, cooker, etc.
  • The polymer composite comprises at least one thermoplastic material; maleic anhydride–grafted polypropylene (MA-g-PP) compatibilizer; at least one antioxidant; at least one lubricant; at least one color masterbatch and as per preference, a mineral reinforcement such as talk, calcite, etc. and/or a fibrous reinforcement
  • The polymer composite of the present invention comprises recycled waste microfiber.
  • Microfibers accumulated in the filtration systems of white goods such as laundry washing machine, laundry drying machine, etc. are recycled and used in the production of the polymer composite of the present invention. Reinforcement of microfibers into the thermoplastic material increases the rigidness of the material, and thus white goods comprising recycled, environmentally-friendly polymer composite with improved mechanical properties and suitable for industrial use can be produced. Moreover, by means of the use of recycled waste microfibers, product costs are decreased.
  • The resistance of the materials against deformation under force is an important parameter in the selection of components. When the mechanical results are examined, by means of the reinforcement of the microfibers into the raw material, the E modulus and the bending modulus of the material significantly increase while the yield strength and the bend strength thereof are improved. Since the losses in the yield strain and impact strength are tolerable, the polymer composite of the present invention can be used in a wide range of product groups. The analyses of the polymer composites of the present invention show that thermoplastic materials such as polypropylene, etc. can be considered as composite with the reinforcement of polyester, polyamide and cotton-based microfibers. Thus, the present invention not only provides cost advantage in the raw material but also allows the use of microfibers which cause problems when released into the environment. Consequently, by means of the present invention, recycled and environmentally-friendly polymer composites with improved mechanical properties are produced while providing cost advantage.
