Abstract

The present invention discloses a wax emulsion for treating board for making pencil. Said wax emulsion is made up by using mineral wax, sterilizing agent, adjuvant, emulsifier, preservative and water according to a certain mixing ratio. The cutting face of the pencil made of the board treated by said wax emulsion is smooth and clean, and said invented wax emulsion can greatly raise quality of the product. As compared with dry board-baking wax-impregnating method said invented method can reduce consumption of wax-like material, also can reduce environmental pollution due to dry baking wax-impregnating method.

Description

technical field [0001] The invention belongs to an impregnating agent for wood, in particular to a wax emulsion for treating wood used for pens. Background technique [0002] The processing of wooden boards is an extremely important process in the production process of wooden pens (such as pencils, cosmetic pens, etc.). The common method is that the wood board must first be baked at a high temperature to oxidize or partially carbonize the lignin and cellulose of the wood, so that the pen can be cut effortlessly. While baking the wood board at high temperature, solid low-melting point wax can also be baked together with the wood board at a temperature of 200-250°C in a roller baking machine, so that some solid hydrocarbon molecules can penetrate into the fiber gaps of the wood board. Because the wax soaked in the wooden board by this dry baking method is very limited, there is a problem that the finished pen is difficult to cut and the cutting surface is rough. Chinese pate...
