Abstract

The invention discloses an impact-resistant high-flame-retardancy PP plate which comprises a PP layer arranged in the middle and reinforcing layers symmetrically arranged on the two sides of the PP layer, and each reinforcing layer comprises an ABS layer, a PTFE layer and a ceramic layer; the PP layer is prepared from the following raw materials: polypropylene, co-polypropylene, a flame retardant, a toughening agent, an antioxidant and color master batch; the preparation method of the PP plate comprises the following steps: 1, preparing the PP layer: (1) weighing raw materials in proportion and stirring, (2) conveying the stirred raw materials to an extruder, and (3) melting and molding the raw materials; and 2, preparing the PP plate: connecting the ABS layers to the two sides of the PP layer through hot melting, then connecting the PTFE layer to the outer sides of the ABS layers through hot melting, and finally adhering the ceramic layer to the outer side of the PTFE layer to obtain the PP plate. The preparation method of the impact-resistant high-flame-retardancy PP plate is simple and reasonable, and has fewer operation processes; and the prepared PP plate has good impact resistance and excellent flame retardant property.

Description

technical field [0001] The invention belongs to the technical field of PP boards, in particular to a PP board with impact resistance and high flame retardancy and a preparation method thereof. Background technique [0002] PP board, also known as polypropylene plastic board, is a semi-crystalline material. It is harder and has a higher melting point than PE material. PP extruded sheet has the characteristics of light weight, uniform thickness, smooth surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation, and non-toxic. PP board is widely used in the production of clothing, felt and other fiber products, medical equipment, chemical containers, and pipelines. However, there are some problems in the existing PP board, such as poor impact resistance, which makes the board easy to cause damage during use, and it is relatively easy to cause cracks, and the flame retardancy is poor, so it cannot be used at high temperature...
