Poplar pencil coating and preparation method thereof

Abstract

The invention provides a poplar pencil coating and a preparation method thereof and relates to the technical field of pump production. The poplar pencil coating is prepared from the following materials: acrylate resin, mica powder, red gold powder, polypropylene adipate, dimethyl silicon oil, isocyanate, ferulic acid, pyrrolidone carboxylic acid, ethyl palmitate, an anti-aging agent, diethylene glycol monobutyl ether, VAE emulsion, white glue, bee wax, an antifoaming agent, a thickening agent, petroleum coke powder, water-based stock white and deionized water. The preparation method comprises the following steps: 1) fully mixing the materials except the liquid material, and then, stirring and dispersing the mixture; 2) fully grinding the solid raw materials, adding all solid raw materials into a container, adding the liquid, carrying out full mixing, and carrying out emulsification treatment; 3) cooling the materials in the step 2) to 50-60 DEG C, and keeping the temperature for 20-30 minutes; and 4) cooling the stirred materials to room temperature, and continuously grinding the materials into a colloid. The poplar pencil coating is not easy to scratch, convenient to produce, long in service life and resistant to water and high temperature.

Description

technical field [0001] The invention relates to the technical field of pencil production, in particular to a poplar pencil paint and a preparation method thereof. Background technique [0002] Poplar is a plant of the genus Populus. There are more than 100 species in the genus. There are about 62 species in my country, of which 57 species are distributed in China, and about 4 species are introduced and cultivated. In addition, there are many varieties, variants and introduced strains. Poplar has a wide range of uses, not only for wood, but also mainly for processing industrial materials. Poplar has become an important additional raw material for plywood, fiberboard, paper-making matches, sanitary chopsticks and packaging. Pencil is a kind of pen used for writing and drawing and sketching. It has a history of more than 400 years. Among them, pencils for drawing and sketching are divided into many types, which are divided into three stages of development, namely Graphite, woo...

AI Technical Summary

Problems solved by technology

For wooden pencils. Pencil shaft materials mainly include wood and glue. Wood is used to make pen shafts, which require upright texture, fine and uniform structure, soft or slightly soft, slightly brittle, less resin, low hygroscopicity, and swelling. Small shrinkage and no deformation. Mainly include pencil cedar (red cedar), cedar, sida, basswood, alder, etc. The adhesive should have appropriate viscosity, fluidity and wettability, and the adhesive layer has toughness after hardening , less damage to the tool, has certain water resistance, heat resistance, aging resistance, easy to cure at room temperature, short hardening time, non-toxic, etc. The wood of poplar is hard, and has high hygroscopicity and poor brittleness. It is not easy to make pencils in technology

The paint on the pencil falls off, and some paints are not waterproof, mildew-proof, etc., which reduces the service life of the pencil
