According to the present invention, with the technical scheme, the production cost is low, the market prospect is good, and the obtained low-odor polypropylene composite material can be used in the vehicle field such as vehicle instrument panels, door protection plates, sub-instrument panels and other vehicle interior and exterior decoration parts, and the household appliance field such as refrigerators and small household appliances.

The invention provides a method for preparing single-piece talcum powder. The method for preparing the single-piece talcum powder by collaborative foaming expansion shear tensile specifically comprises the following steps: firstly, preprocessing the talcum powder by a swelling agent to increase an interval between talcum powder layers so as to enable a foaming agent to be dipped between the talcum powder layers, and enabling the talcum powder layers to relatively slide; utilizing a multistage millstone type mixing mill for shearing and peeling to enable the talcum powder layers to be peeled, and forming the talcum powder of a single-layer laminated structure. The talcum powder prepared with the method is the single-layer laminated talcum powder and has the advantages of high preparation efficiency and high additional value, and the layer structure of the talcum powder is not damaged. The talcum powder is used for composite materials, has a high enhancement function, has transparency, can be widely added into products including plastics, high-class coatings and the like, is suitable for scale production and has an obvious market application value.
