Technical Field

The invention relates to a manufacturing process method of an alloy pen core, in particular to a novel manufacturing process method of an alloy pen core.

Background

The writing core in the market mainly has two basic characteristics, namely a pen, a pencil, a ball-point pen and the like, the ink changing and the pen core changing belong to consumable products, and in the repeated writing process, due to the quality difference, a plurality of unstable factors are caused, the writing effect and the using effect are directly influenced, so that the writing pen which does not use ink, does not need to change the pen core, is difficult to break the pen core and has low price is urgently needed in the market.

Disclosure of Invention

The invention aims to provide a manufacturing process method of a novel alloy pen, which does not use ink or change a pen core, is difficult to break the pen core and is low in cost.

The preparation scheme adopted by the invention is as follows:

a flux, comprising: the activating agent, the thixotropic agent, the resin and the solvent are mixed in equal proportion and then heated to smelt liquid, and the liquid is cooled to be in a solid-liquid coexisting state.

The invention has the beneficial effects that:

the pen core is prepared by heating tin, lead and antimony according to the mass ratio of 61:35:4 to 800 ℃, adding soldering flux, uniformly mixing three metal liquids, and naturally cooling and performing compression molding.

A manufacturing process method of a novel alloy pen core comprises the following steps:

soldering flux; the activating agent, the thixotropic agent, the resin and the solvent are mixed in equal proportion and then heated to smelt liquid, and the liquid is cooled to be in a solid-liquid coexisting state.

A manufacturing process method of a novel alloy pen core comprises the following steps:

a pen core; the tin-lead-antimony composite material is prepared by heating tin, lead and antimony in a mass ratio of 61:35:4 to 800 ℃, adding soldering flux, uniformly mixing three metal liquids, and naturally cooling and performing compression molding.

A manufacturing process method of a novel alloy pen core comprises the following steps:
