Embodiment 1

[0012] The preparation of embodiment 1 soybean protein solution

[0013] First measure 50ml of deionized water and pour it into a three-necked flask, then weigh 2g of soybean protein isolate and pour it into the three-necked flask, and stir in a water bath at 85°C for 1 hour to obtain a soybean protein solution.

Embodiment 2

[0014] The preparation of embodiment 2 soybean protein / microcrystalline cellulose adhesive

[0015] Add 3 mL of methacryloxy-functional silane and 0.5 g of microcrystalline cellulose to the above soybean protein solution, and continue stirring for 1 h in a water bath at 65° C. to obtain a soybean protein / microcrystalline cellulose adhesive.

Embodiment 3

[0016] The mensuration of embodiment 3 soybean protein / microcrystalline cellulose adhesive glue liquid viscosity

[0017] With the soybean protein / microcrystalline cellulose adhesive glue liquid that above example is made, according to GB / T 2794-1995, adopt the rotational viscometer method to measure its viscosity. The measured viscosity is 0.24~12.62Pa.s.

Abstract

The invention discloses a preparation method of a soybean protein / microcrystalline cellulose adhesive. The soybean protein / microcrystalline cellulose adhesive comprises the following components in parts by weight: 100 parts of soybean protein, 2000-3000 parts of water, 0.5-1.5 parts of microcrystalline cellulose and 0.5-1 part of silane coupling agent. The preparation method comprises the following steps: evenly mixing the soybean protein and water, and adding the microcrystalline cellulose and silane coupling agent to carry out combined modification, thereby obtaining the soybean protein / microcrystalline cellulose adhesive. The method disclosed by the invention has the advantages of simple technique, low production cost, no pollution and high binding property, and is convenient to use and applicable to industrial production. The adhesive can be used for binding wood, paper and other fiber materials. Besides, the soybean source is wide, and thus, the adhesive has favorable popularization value.

Description

technical field [0001] The invention belongs to the field of polymer materials and adhesives, and in particular relates to a preparation method of a soybean protein / microcrystalline cellulose adhesive. Background technique [0002] At present, formaldehyde-based adhesives are mainly used in wood adhesives, and formaldehyde volatilized from formaldehyde-based adhesives pollutes the environment and endangers health. Long-term inhalation of a small amount of formaldehyde will cause chronic poisoning. And the raw materials of many formaldehyde-based adhesives are petrochemical products. With the depletion of non-renewable resources such as petroleum, coal, and natural gas, their development is seriously restricted. People urgently need renewable natural adhesives. As one of them, soybean protein is composed of various amino acids connected by peptide bonds. It has the advantages of biodegradability, extremely rich resources, fast regeneration speed, and low price. Therefore, res...
