Abstract
The invention discloses a pencil lead, the surface of which is covered with a membrane, the outer surface of the elongated or bullet-headed pencil lead is covered with a layer of membrane to ensure that the fingers of the user are not dyed black in the process of assembly, and the writing concentration is not effected, the pencil lead has the advantages of facilitating people to use the pencil without timber directly, decreasing the use of timber, saving resources.
Description
Affiliated technical field
The present invention relates to a kind of writing implement, particularly the surface the pencil-lead of film.
Background branch art
At present, the pencil-lead that all propelling pencils use, no matter be lead bullion core, thin lead for retractable pencil, or the sub warhead sample pencil-lead that processes by the lead bullion core, all deceive on its surface, the user will pack these pencil-leads in the pen into hand in use, and the user points nature and dyed black in assembling process.
Summary of the invention:
Do not dyed blackly in order to guarantee that the user points in assembling process, be the invention provides the pencil-lead that a kind of surface film.
The technical scheme that the present invention solves its technical problem is such: at pencil-lead outer surface homogeneous immersion colloidal solution or paint, constitute film on the pencil-lead surface after this colloid material drying or behind the paint curing.This impregnation process can be once to finish, and also can finish several times, and the thickness of film does not dye the evil backstage manipulator when using pencil-lead and refers to, do not influence again and write concentration and be advisable.
The colloid material kind that can select for use is a lot, for example 108 glue, latex, glue, birds, beasts and eggs, thin rice gruel, dextrin that glutinous property is strong, the coating that chemical paste even viscosity are strong; Paint can be all kinds of paint, as the combination of novolaks or polyester lacquer, curing agent, diluent.Can also in the colloid material, add mould inhibitor, anticorrisive agent because of its territory of use's humidity is bigger.
The invention has the beneficial effects as follows: allow the not dirty hand of pencil user, allow people's be more convenient for directly using pencil of no timber, reduce the use of timber, economize on resources.
