Abstract

The invention discloses a bakelite pen tongue and a preparation method thereof. The bakelite pen tongue comprises the following components: a parent material, butadiene rubber, sulfur, a recycled powder material, an oiling agent, a filler and an additive. By using the bakelite recycled material, the problem that part of bakelite is difficult to recycle is solved, and the production cost can be reduced; by adding butadiene rubber, the elasticity, wear resistance and cold resistance of the pen tongue can be improved; by adding yellow vaseline and carbon black, the mechanical property of the pen tongue is improved, and certain blackness is provided, so that the color of the ink is not changed; by adding light calcium carbonate, the tensile strength, wear resistance and tear strength are improved, and the consistency is adjusted; the surface of the pen tongue has good ink-loving wettability, and after the surface of the pen tongue has good wettability, ink can be evenly laid on the surface, and large-particle ink falling cannot be formed.

Description

technical field [0001] The invention belongs to the field of pen production and relates to a feed, in particular to a cost-reduced and improved bakelite feed and a preparation method thereof. Background technique [0002] The pen feed refers to the bracket of the nib of the pen, which is one of the key parts of the ink pen. The main functions of the pen feed are to be beautiful, to support the nib, to provide ink, to replenish the air in the ink bag / tank, and to provide a temporary storage place for the ink produced by the change of air pressure in the ink tank. [0003] The function of the pen feed is to store excess ink and supply it to the nib. Once a large amount of ink flows out of the pen case due to air pressure and vibration, the vertical and horizontal grooves on the tongue of the pen will play the role of "blocking floods and storing water". Once the pen case is out of water, the tongue will store it again Ink continues to be supplied to the nib. [0004] The ma...
