Highly filled polymer composition with improved properties

A highly filled polymer composition with improved properties comprising: a continuous matrix material; a filler material in an amount of 10 to 80 wt. % of said composition; a polymer plasticizer dispersed in said continuous matrix material in an amount of 0.5 to 15 wt. % of said filler; a filler coating material which coats said filler particles in the form of a continuous coating layer thus forming coated filler particles; a diffusion zone around said coated filler particles where said filler coating and said continuous matrix material are mutually diffused into one another wherein said filler coating material is distributed with concentration decreasing in the direction outward from said continuous coating layer. Provided also is a method of preparing the aforementioned composition which guarantees that during extrusion or similar treatment the filler particles are coated with a continuous layer of the filler coating material and that the aforementioned diffusion zone is formed around the coated filler particles. In the manufacture of various products such as pipes, sheets, profiles, etc., the composition of the invention combines high deformation capacity with sufficient strength. Furthermore, the composition of the invention possesses high anticorrosive properties, has low shrinkage, and has high adhesion to metals, wood, plastics, etc.

Method for reclaiming carbon fiber reinforced epoxy resin composite material

The invention relates to a method for reclaiming a carbon fiber reinforced epoxy resin composite material. The conventional method is high in equipment requirement and high in reclamation cost. The method comprises the following steps of: adding a catalyst into an organic reagent to prepare supercritical CO2 composite solution; putting the carbon fiber reinforced epoxy resin composite material tobe decomposed into a reaction kettle, and adding the supercritical CO2 composite solution; and reacting for 1 to 24 hours at the temperature of between 100 and 250 DEG C under the pressure of 7.5 to 25.0MPa, cooling the product to normal temperature, washing and drying the solid product in the product to obtain carbon fibers, and performing reduced pressure distillation on the liquid product in the product to obtain phenol and derivatives thereof. The catalyst is one or two of liquid super acid, solid super acid, phosphotungstic acid, phosphomolybdic acid, acetic acid, formic acid, hydrochloric acid, sulfuric acid and nitric acid. The method has the advantages of high degradation efficiency, environmental friendliness, low cost and the like, and is a green method for reclaiming the waste and old carbon fiber reinforced epoxy resin composite material.
