The preparation method comprises the following steps: soaking soybeans in water for 24 hours, grinding the wet beans and water according to a ratio of 1:3, and then filtering by using gauze to obtain the soybean milk; adding the soybean milk and the sesame oil according to a ratio of 3:1 into a reaction container, and stirring for 5-15 min; mixing an obtained mixture and the resin according to a ratio of 4:1, putting into a paint mixer, stirring for 20-50 min, adding the plasticizer, the edible pigment additive and the edible essence while stirring, then stirring for 5-20 min, and filtering to obtain the safe, non-toxic and fragrant pencil paint.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a safe, non-toxic and scented pencil paint and a preparation method thereof. Background technique [0002] Existing pencils are embedded in wooden penholders by strip-shaped pen cores, and then the penholders are polished and varnished. In the existing production technology, the pen cores are generally made of graphite powder and clay mixed, and the penholders of pencils are generally made of wood. In the cutting process, logs are made into cylindrical, regular hexagonal or regular octagonal penholders, which are heated through the core, and then polished, polished, and painted to make the finished product. Although the refill has been mixed with lead-free graphite powder and clay, the phenomenon that children's long-term use of pencils leads to lead poisoning and affects intellectual development still exists. Lead-poisoned refills, but in the process of painting, the paint contain...
