Recyclable novel composite material

Abstract

The invention discloses a recyclable novel composite material. The recyclable novel composite material comprises the following components in percentage by weight: 5%-20% of waste polypropylene plastics, 30%-60% of polypropylene, 10%-45% of fiberglass, 5%-10% of plasticizer, 1%-10% of mica, 0.3% of toughener (SEBS), dicumyl peroxide, antioxidants and a slipping agent. The recyclable novel composite material provided by the invention is reasonable in formulation, low in cost and high in practicality, and the prepared plastic composite material is short in molding period, good in flexibility and low in density; and is recyclable, which is known as a green industrial material in the 21st century. The application fields of the composite material are developed from the field of automobile industry to the fields of building industry, chemical preservation, sport equipment, furniture manufacturing and the like.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a novel recyclable composite material. Background technique [0002] Thermoplastic composite materials were developed abroad in the mid-1940s. After nearly 70 years of development, the technology and process have been perfected day by day, and the variety and output have also expanded and increased. The matrix resin used is mainly polypropylene (PP) resin, which has a short molding cycle, good toughness, low density, and can be recycled. It is called a green industrial material in the 21st century. Its application fields have developed from the automobile industry to the construction industry, chemical industry Anti-corrosion, sports equipment, furniture manufacturing and other fields.

AI Technical Summary

Problems solved by technology

[0003] The characteristics of existing products: the current formula and production process mostly use chopped fiber granulation, the mechanical properties of the products are obviously higher than those of the matrix resin, and it is easy to form products with complex shapes, but due to the high viscosity of the resin itself, the reinforcement fiber is limited Added amount

The addition of glass fiber is not high, resulting in low strength, uneven fiber distribution, uncontrollable orientation of glass fiber, low output, high production cost, etc., which limits their impact resistance and corrosion resistance.
