Abstract

The invention relates to the technical field of polycarbonate, and discloses a functional nano-zinc oxide modified polycarbonate sheet material, nano-zinc oxide reacts with methacrylic acid 2-isocyanate ethyl ester to obtain alkenylated zinc oxide, the alkenylated zinc oxide reacts with tris (2-aminoethyl) amine to obtain aminated zinc oxide, the aminated zinc oxide reacts with maleic anhydride grafted polypropylene to obtain a functional nano-zinc oxide modified polycarbonate sheet material, and the functional nano-zinc oxide modified polycarbonate sheet material is obtained. The functional nano-zinc oxide modified polycarbonate plate is finally obtained by mixing the maleic anhydride grafted polypropylene modified zinc oxide with polycarbonate and pressing the mixture through a press vulcanizer, and the nano-zinc oxide and the maleic anhydride grafted polypropylene can absorb and disperse stress. The maleic anhydride grafted polypropylene grafted on the surface of the nano zinc oxide is used as a flexible long chain to be added into a composite board matrix, so that the flexibility of the polycarbonate matrix can be effectively improved, the capability of the composite board for absorbing plastic deformation work is improved, and the comprehensive properties such as toughness of the composite board are further enhanced.

Description

technical field [0001] The invention relates to the technical field of polycarbonate, in particular to a functional nano zinc oxide modified polycarbonate plate and a preparation method. Background technique [0002] Polycarbonate is an engineering plastic variety second only to nylon among the five major engineering plastics. It has excellent properties such as high temperature resistance and high transparency. Since the industrial production of this material, it has been widely used in many fields such as electronic appliances, automobile manufacturing, and household appliances. In this industry, the board prepared with polycarbonate as the matrix has been gradually applied to the construction industry in recent years, but for this special industry, polycarbonate is required to have higher strength and toughness, but the polycarbonate structure contains A large number of bisphenol A structures are easy to cause stress concentration on itself, which leads to a greater test ...
