Embodiment Construction

[0033] The present invention relates to composite materials obtained from thermoplastic materials such as conventional polymers and biodegradable biopolymers as well as proteinaceous materials. Using castor bean cake, blends were prepared from polyhydroxyalkanoates (PHAs), high-impact polystyrene (HIPS), polypropylene (PP) and linear low-density polyethylene (LLDPE), varying particle size, filler content and The time it took to prepare the mixture. The mixture of castor bean residue and the polymer was prepared in a Haake Rheocord 9000 mixing chamber.

[0034] Mixtures were prepared with the four different polymers (PHB, HIPS, PP and LLDPE) using well pulverized and sieved natural and solid state fermented castor bean residues. The weight percentage of the protein material is 5-60%; the particle size of the castor bean residue is 45-256 μm, and the mixing time is 5-10 min. The mixture is homogenized at a temperature between 20°C and 200°C and then shaped.

Abstract

The present invention relates to a composite material, and a preparation method of the composite material which contains a traditional thermoplastic material, a biodegradable thermoplastic biopolymerand a protein material. In the invention, castorseed cake is used as a filler for producing the composite material which is prepared by the widely available polymer, such as high impact polystyrene (HIPS), linear low density polyethylene (LLDPE), polypropylene (PP) and a biodegradable biopolymer such as polyhydroxyalkanoates. The composite material obtained from the mode of the invention has goodmechanical property and heat property. A series of prepared composite material can be used for the industries which require using the wood for large amount and the industries in the fields of civil engineering, and can be used in the disposable product.

Description

field of invention [0001] The present invention relates to composite materials based on thermoplastic materials and proteinaceous materials and methods for their production to replace conventional plastics in order to avoid environmental problems caused by the large-scale use of plastics of petrochemical origin. More specifically, the present invention uses a proteinaceous material, such as castor bean cake, as filler for the production of said composite made of widely available polymers, with the aim of increasing the biodegradability of said material without compromising its mechanical properties. properties because these polymers are widely used in the production of products with a short service life, such as disposable cups, plastic bags, jars and packaging. Background of the invention [0002] The widespread consumption of traditional plastics to replace other materials such as wood, glass and steel has raised enormous concerns among some governments and the general pub...
