Abstract

The invention relates to an environment-friendly stone paper extrusion forming screw. The environment-friendly stone paper extrusion forming screw comprises a shaft portion, a connecting handle arranged at the end of the shaft portion and used for being connected to extrusion equipment and a thread arranged on the shaft portion. A pressure stabilization segment is arranged on the screw. A shaft portion of the pressure stabilization segment is equal in diameter, a thread of the pressure stabilization segment is equal in pitch, a chamfer R2 on the rear side of the thread of the pressure stabilization segment is 2-3 times the angle of a chamfer R1 on the front side, the radius range corresponding to the chamfer R1 on the front side of the thread of the pressure stabilization segment is 3-7 mm, and the radius range corresponding to the chamfer R2 on the rear side is 6-19 mm. The invention relates to an environment-friendly stone paper extruder which comprises a screw and a screw barrel. The invention further relates to a stone paper production process. The environment-friendly stone paper extrusion forming screw, the environment-friendly stone paper extruder and the stone paper production process have good dispersity to materials, the stable extrusion quantity and extrusion pressure and are especially suitable for extrusion production of stone paper formula materials.

Description

technical field [0001] The invention relates to the field of production equipment for environment-friendly stone paper, in particular to an extrusion molding screw for environment-friendly stone paper, an extruder and a production process for stone paper. Background technique [0002] Stone paper is a new type of material between paper and plastic, which can replace some traditional functional paper, professional paper, and most of the traditional plastic packaging. It can save a lot of forest resources for the society and reduce the secondary pollution produced in the papermaking process. Stone paper is made of limestone mineral resources with large reserves and wide distribution as the main raw material (calcium carbonate content is 70-80%), with polymer as auxiliary material (content is 20-30%), using the principle of polymer interface chemistry and The characteristics of polymer modification, after special process treatment, it is made by polymer extrusion and blow mold...
