Antiskid pencil paint and process for producing coated pencil by using same

Technical Field

The application relates to the field of pencils, in particular to an anti-skid pencil paint and a process for producing coated pencils by applying the same.

Background

The pencil paint is paint which is coated on the surface of the wooden pencil holder to improve the appearance of the wooden pencil holder. The pencil paint can prevent the pencil holder from bending deformation and glue opening caused by moisture absorption from the air, and prolong the storage time and the service life of the pencil.

The nitrolacquer has the characteristics of quick drying and good decoration, so that the application of the nitrolacquer in the pencil lacquer can improve the production efficiency of enterprises and reduce the production cost. Generally, the paint coated on the surface of the pencil is called pencil paint, generally adopts cellulose nitrate as a main raw material and is divided into three types of priming paint, finish paint and varnish, wherein the priming paint is directly coated on the surface of a wooden pole to fill up the wood grain and uneven parts of the wooden pole, and the paint contains more filling pigment; the finish paint is coated on the primer so that the pencil can have the required color; the varnish is glossy, color free, contains a large amount of low viscosity nitrocellulose and synthetic resin. The pencil paint coated on the surface of the wooden pencil can prevent the pencil holder from bending deformation and glue opening caused by moisture absorption from the air, and can prolong the storage time and the service life of the pencil. In addition, after the pencil is painted, the pencil is elegant in shape, bright in pen holder and bright in paint film, and gives people aesthetic feeling, and even if dust is stained on the pencil, the original aesthetic feeling and luster can be recovered once the pencil is wiped.

With respect to the related art in the above, the inventors consider that: the wooden pencil surface after the japanning is comparatively smooth, and in long-time use, the hand glides easily, needs constantly to adjust and holds a distance, and need squeeze the pen-holder hard and just can hold the pencil firmly, arouses hand fatigue easily.

As can be seen by combining examples 1-3 and Table 2, the anti-slip pencil paint prepared by the method has good anti-slip performance, adhesion performance and leveling property, wherein the performance of example 2 is better.

As can be seen by combining examples 1-5 and Table 2, the prepared anti-slip pencil paint has better anti-slip property, adhesion property and leveling property when the grain diameter of the sand flour is 150 μm.

Combining examples 1-5 and comparative examples 1-3 and combining Table 2, it can be seen that when 5-500 μm of sand flour is added to the nitropencil paint, the resulting non-slip pencil paint has good non-slip properties, adhesion properties and leveling properties.

By combining the examples 2, 10-11 and the comparative examples 4-7 and combining the table 2, it can be seen that when the mass part ratio of the ethyl acetate to the butyl acetate is 1:2, the sand powder and the nitropencil paint have good dispersibility in the mixed solvent, so that the sand powder particles can be reasonably combined with the nitropencil paint, and the prepared anti-skid pencil varnish has excellent anti-skid property, leveling property and adhesion property.
