Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with specific embodiments, but not limited to specific examples.

[0009] The concrete implementation steps of the synthetic method of soybean protein adhesive are:

[0010] 1. Pretreat the soybean protein and urea solution with a solid-to-liquid ratio of 1:10 in the pumping bath for 10-20 minutes.

[0011] 2. Then, 0.8 g of potassium persulfate and 0.2 g of sodium sulfite are respectively configured into solutions with a concentration of 30% and added to the pretreated reaction solution and continuously stirred with a stirrer to make it fully react.

[0012] 3. After 10 minutes, add methyl glycidyl methacrylate to react for 3-5 hours,

[0013] 4. Put it in the refrigerator to refrigerate.

Abstract

The invention relates to a method for synthesizing a biological adhesive, in particular to a method for synthesizing a soybean protein adhesive. Compared with the prior method, the method has the characteristics of short pretreatment time, short reaction time, and good water resistance, is simple, convenient and feasible, and also greatly improves the bonding strength of adhesives.

Description

1. Technical field: [0001] The invention relates to a synthesis method of biological adhesives, in particular to a synthesis method of soybean protein adhesives. 2. Background technology: [0002] Soy protein is a natural protein polymer and a biodegradable organic material. In recent decades, due to the limited global petroleum resources and the existence of a large amount of toxic and volatile formaldehyde in synthetic resin adhesives, which endangers human health, the research on soybean protein adhesives has become a hot research topic. At present, the synthesis methods of soybean protein mainly include: low alkali amount, low liquid ratio, high strength denaturation method and homogenized soybean protein method. Although the soybean protein adhesive synthesized by the above method has certain bonding strength, it is lacking in pretreatment time and water resistance. 3. Contents of the invention: [0003] The purpose of the present invention is to overcome above-ment...
