Benefits of technology

This patented technology involves mixing different types of raw ingredients together into crumbles that can be easily molded down on demand without leaving any residue behind when they break off during production. These filled sheets made from this mixture help reduce waste while still maintaining their strength over time. They also provide good print quality due to its ability to absorb water vapor even after it evaporation.

Problems solved by technology

This patented technical solution involves developing synthesis papers for use in various industries like civil engineering or industrial production processes due to their ability to reduce waste emissions while maintain good quality material resources. These synthesives can include modifying minerals, polymers, resins, admixtures, solvents, surfactants, lubricant oils, and biological agents. However, there exist challenges associated with producing durability syntenic paper suitable for disposal purposes without causing damage to our natural environments.

Abstract

The invention relates to a degradable synthetic paper material and a preparation method thereof. The degradable synthetic paper material comprises the following components in part by weight: 100 parts of plastic resin, 50 to 600 parts of starch filler, 50 to 300 parts of inorganic filler and 10 to 100 parts of auxiliary agents. The preparation method comprises the following steps of: adding dried polymer resin, starch, a modified inorganic filler and various auxiliary agents into a high-speed material-mixing machine with a heating device according to a certain ratio; mixing the components at the temperature of between 80 and 90 DEG C for 2 to 15 minutes; extruding the mixed materials by using a double-screw extruder for pelleting; and performing extruding blow moulding on the pelleted granular materials to obtain the degradable synthetic paper. The degradable synthetic paper material and the preparation method thereof have the characteristics of low cost, simple preparation process, no environmental pollution in the production process and the like. The synthetic paper can be used for writing and printing, has excellent mechanical properties, and can be subjected to controlled degradation by a soil buried method or a solarization method.
