Abstract
The present invention relates to a polymer composite produced to be used in white goods and to the production method thereof.
Description
- The present invention relates to a polymer composite, to the production method thereof and the use thereof in white goods.
- Vacuum Insulation Panels (VIP) which are used as insulation material cannot be recycled. The vacuum insulation panels cause serious problems such as clogging in recycling machines, which prevents the same from being recycled. This material which is now waste seriously harms the environment and causes serious problems in terms of costs.
- In the state of the art American Patent Application No. US 4,446,090, a method is disclosed, for obtaining a thermoplastic polymer by using materials containing silicone such as silica, talk, fumed silica, etc. as additive to cross-link thermoplastic polymers.
- The state of the art German Patent Application No. DE 199915311 A relates to a seven-layer vacuum insulation panel with improved insulation properties.
- The aim of the present invention is the realization of white goods comprising polymeric composites obtained by recycling the Vacuum Insulation Panels (VIP) used as insulation materials and adding the resulting material into the polypropylene matrix.
- The polymeric composite realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a polypropylene (PP) matrix, powdered waste vacuum insulation panel (VIP) and maleic anhydride-grafted polypropylene (MA-g-PP). Optionally, mineral additives such as calcite, talk, etc. and fiber additives such as glassfiber and carbon fiber can be added.
- The polymeric composite of the present invention is used in white goods such as washing machine, dishwasher, laundry dryer, oven, air conditioner, small appliances, etc., in particular in refrigerators.
- The polymeric composite of the present invention comprises a polypropylene (PP) matrix and maleic anhydride-grafted polypropylene (MA-g-PP). MA-g-PP interacts with the silica, glassfiber and silicon carbide present in both polypropylene matrix and the vacuum insulation panel (VIP) filler, thus making the filler and the polymer matrix compatible. Thus, the physical and mechanical properties thereof given below are improved.
- The polymeric composite of the present invention comprises powdered waste vacuum insulation panel (VIP).
- Waste vacuum insulation panels which cannot be recycled are used as filler in the polymeric composite, thus significantly improving the mechanical properties of raw materials. While in the PP matrix with the silica-based vacuum insulation panel (VIP) filler and MA-g-PP additive, the existing flexibility and lightness of the PP material can be partially retained, the silica, glassfiber and silicon carbide therein significantly improve tensile and yield strength, Young modulus, E modulus and bend strength. By using the waste vacuum insulation panel material in the PP matrix, cost advantage is provided in raw material costs, and the waste vacuum insulation panel contents are prevented from harming the environment.

Table 1 Vacuum Insulation Panel Components. By mass % Silicon (SiO 2 ) 75 Glassfiber 15 Silicon carbide (SiC) 15 - In an embodiment of the present invention, the polymeric composite comprises 50-94% polypropylene (PP) matrix, 5-40% powdered waste vacuum insulation panel (VIP) and 3% maleic anhydride-grafted polypropylene (MA-g-PP). In a preferred embodiment of the present invention, 77% PP, 20% VIP and 3% MA-g-PP by weight are used.
- The VIP filler increases the strength of the material while decreasing the elongation at yield value. Therefore, the elongation at yield value obtained by using 5-40%, preferably 20% VIP by weight is suitable for white goods applications.
