Embodiment 1

[0017] Example 1: In a reactor with a capacity of 1 ton, first put all the 905 emulsion into the reactor, start the motor, stir at a speed of 50-60 rpm for 5-10 minutes, then slowly add cornstarch, control Keep the rotation speed at 50-60 rpm to ensure that the cornstarch is evenly dispersed without agglomeration. After stirring for 20-30 minutes, add defoamer to the reactor and reduce the rotation speed to 40-50 rpm to prevent the occurrence of Bubbles, then add 6064 emulsion, and finally add preservatives, stir thoroughly for 30 to 40 minutes, adjust the pH value to 6, seal the reaction kettle, and vacuum to ensure that the glue will not produce air bubbles.

Abstract

The invention discloses solvent-resistant glue used for sealing edges of furniture and a processing method thereof. The formula of the glue comprises the following components: 5-10 percent of water soluble polyurethane emulsion, 15-25 percent of 905 emulsion, 50-60 percent of 6064 emulsion, 15-20 percent of corn starch, 0.5 percent of defoaming agent and 0.2 percent of preservative. By adding water-containing copolymer emulsion without a surfactant, the invention enhances the solvent resistance of the glue and the adhesiveness of the glue to a coated substrate greatly. Moreover, the invention has the advantages of simple manufacturing process and cost saving and conforms to the technological requirement of putting into the industrialization production.

Description

technical field [0001] The invention relates to a glue used for edge sealing of furniture, in particular to a solvent-resistant glue used for waterproof edge sealing on the wood fiber surface of a solid wood substrate, and also to a processing method of the glue. Background technique [0002] Modern panel furniture uses wood-based panels such as medium density fiberboard, high density fiberboard, particleboard, plywood, etc. as the base material, so there is a problem of edge sealing of the panel. The adhesiveness of the edge banding glue and the heat resistance in subsequent processes such as heating directly affect the quality of the edge banding. External moisture can easily enter the interior of the board from the exposed wood fiber surface around the board, causing expansion and deformation around the board. , have a great impact on the appearance and use effect. The most common one in the market at present is EVA hot melt adhesive, which is a general-purpose adhesive ...
