Abstract

The invention provides a composition of a novel synthetic paper material and a preparation method. The invention comprises the following components in weight percent: 50-85% of polyolefin blend, 10% of inorganic mineral powder and 5-12% of auxiliary agent; then 0.1-1% of antioxidant calculated according to the total weight the above materials is added for pre-mixing; then a double-screw extruder is utilized for extrusion and pelletizing to manufacture into base resin with high steel and high toughness; and the comprehensive performances are all better than ordinary PP synthetic paper material,thus expanding the application range, and simultaneously by adding auxiliary agent (anti-static agent, antibacterial agent, aromatizing agent and the like), and by the processes of fusion, blending and even dispersion in the resin base body, different functional requirements can be satisfied. The paper manufactured from the high-performance PS and PP alloy novel synthetic paper material can be widely used in packaging, high-quality printed matters, tags, paper money, developing paper, tracing paper, express envelopes, paper fans, umbrellas and the like, can save a large amount of forest resource and water resource, and reduces sewage treatment pressure and energy consumption.

Description

technical field [0001] The invention belongs to the technical field of new synthetic paper materials, and in particular relates to a novel PS / PP synthetic paper material with improved impact performance, tensile performance, bending performance, chemical corrosion resistance, surface polarity and surface hardness. Background technique [0002] Synthetic paper is made of thermoplastic high polymers such as polyethylene, polypropylene, polystyrene, polyvinyl chloride. . Synthetic paper is divided into PP synthetic paper, HDPE synthetic paper, PS synthetic paper, PVC synthetic paper, PET synthetic paper, ABS synthetic paper, etc. [0003] In today's world, especially in my country, due to the dwindling forest resources, the demand for paper raw materials has become a new problem. The production process of synthetic paper mainly uses polypropylene and calcium carbonate powder, which can not only solve the problem of raw materials, but more importantly, these two raw materials ...
