Problems solved by technology

Due to the high brittleness of the existing hot-press glue after curing, the glue layer will easily break after the wood veneer is used for a period of time, making the veneer easy to warp and fall off, affecting the normal use of the wood veneer and shortening the wood veneer service life
Therefore, there is the problem that the service life of wood veneer is short in existing technology

Abstract

The invention discloses a production process of an adhesive for veneer, and the production process comprises the following steps: A, mixing polyvinyl alcohol with one-third part by weight of deionizedwater to obtain a product a; B, sequentially adding methylacrylic acid, polyvinyl acetate, ammonium persulfate and sodium polyacrylate into the product a, and stirring evenly to obtain a product b; C, adding one quarter part by weight of a cross-linking agent to the product b, stirring to obtain a product c1, then warming the product c1 up to 60-70 DEG C, keeping warm for 10-15min, and naturallycooling to room temperature to get a product c; D, then pouring sequentially methylparaben, hydroxyl terminated polysiloxane and monodisperse polystyrene microspheres into the product c to obtain a product d; and E, pouring sequentially the remaining parts by weight of the deionized water, nano-activated carbon and the remaining parts by weight of the crosslinking agent into the product to d obtain a product e, warming the product up to 50-65 DEG C, stirring for 20-30min, and naturally cooling to get the finished product. The adhesive has the characteristics of being able to effectively improve the service life of a wood veneer panel.

Description

technical field [0001] The invention relates to an adhesive for veneer, in particular to a production process for the adhesive for veneer. Background technique [0002] The wood veneer is usually composed of a veneer and a base plate, and the veneer is adhered to the base plate by hot-pressing glue, and bonded by hot pressing. Due to the high brittleness of the existing hot-press glue after curing, the glue layer will easily break after the wood veneer is used for a period of time, making the veneer easy to warp and fall off, affecting the normal use of the wood veneer and shortening the wood veneer service life. Therefore, there is the problem that the service life of wood veneer is short in existing technology. Contents of the invention [0003] The object of the present invention is to provide a production process of an adhesive for veneer. The invention has the characteristics of effectively improving the service life of the wood veneer. [0004] Technical scheme o...
