Problems solved by technology

The isocyanate adhesive of the present invention has excellent bonding strength, good water resistance, no environmental pollution, is easy to implement and low in price, reduces the cost, and broadens the application environment. When put on, the bonding strength with the willow wood surface is average. After a long time, it is easy to crack and fall off, making it impossible to continue to maintain the bonded state

Abstract

The invention discloses a preparation method of an adhesive for willow artware. The preparation method comprises the following steps of: under the catalytic action of a catalyst, carrying out hydroxylfluorosilicone acidification treatment on soybean protein to obtain a composite soybean protein degradation solution; carrying out blending treatment on the composite soybean protein degradation solution and toluene diisocynate dissolved by acetone, respectively carrying out high-speed stirring treatment twice at 40-45 DEG C and 55-60 DEG C, and performing concentration and acetone removal so asto obtain the adhesive for the willow artware. The adhesive prepared by the preparation method of the adhesive for the willow artware has excellent bonding strength and can be better applied to bonding of the willow artware.

Description

technical field [0001] The invention belongs to the technical field of handicrafts, in particular to a method for preparing an adhesive for willow handicrafts. Background technique [0002] Wooden handicrafts are made by using various kinds of wood as the main raw material, and are made manually or by machines. They have high use value and artistic value, and are widely favored by consumers. [0003] Willow wood structure is fine, soft, smooth after planing, flammable, slightly poor anti-corrosion ability. Whitewood width varies with growing conditions and is light beige in color. Its heartwood is the exact opposite in color, ranging from reddish brown to brownish gray. Willow has a fine, even grain, although usually straight, sometimes cross-grained, or rounded. [0004] Wooden handicrafts made of willow wood will be bonded with adhesives during processing. For example, the "application number CN201711062345.X" disclosed in the prior art is an isocyanate adhesive. The pr...
