Abstract

The invention discloses hot sol for preparation of an aspen wood pencil and a preparation method thereof and relates to the technical field of pencil production. The hot sol comprises, by weight, 100 to 120 parts of UF resin, 10 to 20 parts of peach gum, 10 to 20 parts of metal soap, 10 to 20 parts of triethanolamine oleic soap, 6 to 10 parts of a curing agent, 30 to 50 parts of a filler, 5 to 9 parts of a modifier and 90 to 110 parts of water. The method comprises 1) orderly adding the UF resin, peach gum, metal soap, triethanolamine oleic soap and water into a mixer and carrying out full stirring blending, 2) grinding all the solid raw materials to obtain powder, adding all the solid raw materials into a container and carrying out full mixing emulsification until there is no air mass in the raw materials in the mixer, 3) adding a curing agent into the emulsion and carrying out stirring for 5-10min, and 4) adding a modifier into the mixture and carrying out stirring. The hot sol has the advantages of good thermosetting property, high viscosity, high strength, good endurance, slow deterioration, good water-proofing effect, long service life of the plywood and low cracking possibility.

Description

Technical field: [0001] The invention relates to the technical field of pencil production, in particular to a hot melt adhesive for making pencils from poplar wood 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 o...
