High-viscosity extrusion forming agent

Abstract

The invention discloses a high-viscosity extrusion forming agent, comprising the following ingredients: 15-20 wt% of rosin modified resin, 10-15 wt% of paraffin No.58, 20-25 wt% of paraffin No.43, 25-30 wt% of paraffin oil, 5-10 wt% of dibutyl phthalate (DBP), 1-5 wt% of coconut amine, and 5-10 wt% of oleamide. According to the invention, extrusion billets can be prevented from cracking in the quick drying process, the extruded billets can be guaranteed to have good shape retention, and the qualified rate of the products is raised.

Description

technical field [0001] The invention relates to a high-viscosity extrusion molding agent. Background technique [0002] At present, the cemented carbide extrusion molding agent mainly adopts the paraffin (solvent-containing) process system. The viscosity of paraffin wax itself is low, and the paraffin wax (solvent-containing) extrusion molding agent process contains a certain amount of oil components. During the rapid drying process, the extruded billet extruded by this forming agent process is affected by the violent volatilization of the solvent and the low viscosity of the paraffin itself, which easily causes drying cracks, resulting in a low product qualification rate. [0003] In view of this, the inventor improves the existing cemented carbide extrusion molding agent, and this case arises from it. Contents of the invention [0004] The purpose of the present invention is to provide a high-viscosity extrusion molding agent to prevent the compact from drying and crac...
