Abstract

The invention discloses formaldehyde-free plant adhesive and its manufacturing process. The manufacturing process is characterized by comprising the following steps: S1, material preparation: taking fresh bamboo, washing and airing, rolling the bamboo by a thread rolling machine to obtain 0.1-0.2 mm bamboo fiber so as to obtain a first prefabricated material; S2, cooking: cooking the first prefabricated material in a cooking tank at the cooking temperature of 160-200 DEG C for 10-30 min so as to obtain a second prefabricated material; S3, squeezing: squeezing the second prefabricated material obtained in the step S2 by a squeezer for 5-10 min to squeeze out a juice so as to obtain a third prefabricated material; S4, distillation: sending the third prefabricated material obtained in the step S3 into distillation equipment to dry moisture, drying by distillation and purifying the material to 90% so as to obtain a fourth prefabricated material; and S5, modulation of pH value, viscosity and dilutability: regulating pH value of the fourth prefabricated material obtained in the step S4 to 8-9%, adjusting viscosity of the material to 19-21 Pa / s, and thermocuring the material for 50-70s so as to obtain a finished product, namely the formaldehyde-free plant adhesive. By using bamboo fiber as a raw material, the formaldehyde-free plant adhesive is pollution-free and environmentally friendly.

Description

technical field

[0001] The invention relates to the technical field of handicraft manufacturing, in particular to a formaldehyde-free vegetable glue and its manufacturing process. Background technique

[0002] Fiberboard is a wood-based panel made by interweaving lignocellulosic fibers and utilizing their inherent adhesive properties. Adhesives and / or additives can be applied during the manufacturing process.

[0003] Fiberboard, also known as density board, is a wood-based panel made of wood fiber or other vegetable fiber and applied with urea-formaldehyde resin or other suitable adhesives. Adhesives and / or additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small difference in vertical and horizontal strength, and is not easy to crack. It has a wide range of uses. It takes about 2.5 to 3 cubic meters of wood to manufacture 1 cubic meter of fiberboard, which can replace 3 cubic meters of sawn timber or 5 cubic mete...
