Problems solved by technology

[0002] At present, the non-slip pencils on the market are mainly composed of a pen core, a pen holder, and several bumps. The bumps are made of plastic materials. During friction between fingers and bumps, the bumps are easy to fall off from the pencil. On the one hand, the anti-skid performance of the pencil is reduced, the use effect is reduced, and the aesthetics are poor. On the other hand, when children use the pencil, the bumps that fall off are easy to adhere to On the fingers, it is easy to be eaten by children, causing children's health to be affected, and the actual application effect is poor

Abstract

A pencil, comprising a penholder, the outer surface of the penholder is coated with a paint layer, a group of bumps are cured on the paint layer, the bumps are a preparation, the preparation is cured on the paint layer on the outer surface of the penholder, and the preparation is UV ink , is prepared from the following raw material proportions by weight: prepolymer, reactive diluent, photoinitiator, pigment, thixotropic agent, dispersant, defoamer, and polymerization inhibitor. The beneficial effects of the present invention are: the bonding ability of the bumps and the paint layer is improved, the adhesion of the bumps on the paint layer is enhanced, the overall adhesion of the bumps is strong, and the bumps cannot be pulled out on the paint layer by normal force It ensures that the bumps will not fall off from the pencil, improves the anti-skid performance of the pencil, and at the same time prevents children from eating the bumps by mistake, ensuring that children's health will not be affected, and the use effect is good, which is conducive to promotion.

Description

technical field [0001] The invention relates to the technical field of pens, in particular to a pencil. Background technique [0002] At present, the non-slip pencils on the market are mainly composed of a pen core, a pen holder, and several bumps. The bumps are made of plastic materials. During friction between fingers and bumps, the bumps are easy to fall off from the pencil. On the one hand, the anti-skid performance of the pencil is reduced, the use effect is reduced, and the aesthetics are poor. On the other hand, when children use the pencil, the bumps that fall off are easy to adhere to Fingers are easy to be eaten by children, causing children's health to be affected, and the actual application effect is poor. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems in the prior art, and provides a pencil, which solves the problem that non-slip pencils are easy to fall off, and meets the needs of pencil users. [0004] T...
