[0026] Embodiment 1~3 and comparative example 1 wood industry plant adhesive

[0027] The first preparation material is:

[0028] Prepare a solid content of 30% sodium hydroxide aqueous solution for subsequent use;

[0029] Preparation concentration is the phosphoric acid aqueous solution of 15% standby;

[0030] Prepare alum, ferrous sulfate and anhydrous calcium chloride 1:1:1 (weight ratio) and mix for subsequent use;

[0031] Prepare water: the (weight ratio) aqueous solution of borax=20:1 is standby;

[0032] Prepare a 30% aqueous urea solution, and then dissolve sodium hexametaphosphate into the 30% aqueous urea solution to prepare a polymerization inhibitor for future use.

[0033] a. Disperse the vegetable starch binder and the bond strength modifier in water under stirring at a rate of 200rpm; after the dispersion is uniform, add a stabilizer and mix uniformly; Butyl ester to suppress the bubbles generated under stirring, and continue to disperse for 10 to 15 minu...

Abstract

The invention discloses a wood industry vegetable adhesive. The wood industry vegetable adhesive comprises a plant starch adhesive, a bonding strength modifier, an oxidizing agent, a pasting agent, across-linking agent, a polymerization inhibitor, a catalyst and water. The plant starch adhesive is selected from cassava starch, sweet potato starch and/or corn starch, preferably the cassava starch;the cross-linking agent comprises a first cross-linking agent borax, a second cross-linking agent sodium trimetaphosphate and a third cross-linking agent epoxy chloropropane. According to the wood industry vegetable adhesive prepared by multiple cross-linking reaction steps in the invention, molecules of the wood industry vegetable adhesive form stable chemical bonds of a multi-dimensional network structure, and the water resistance and bonding strength of the wood industry vegetable adhesive are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a wood industry plant adhesive and a preparation method thereof. Background technique [0002] In recent years, air pollution poisoning incidents after interior decoration have occurred continuously. After the renovation of a certain elementary school, students collectively experienced poisoning and vomiting incidents; after the renovation of a college dormitory, the air was seriously polluted, and the incident of students sleeping outdoors collectively triggered a group incident of some parents besieging the school, causing public opinion. At present, domestic building decoration materials and wood industry adhesives are basically chemically synthesized resin materials such as urea-formaldehyde glue, phenolic glue, melamine-formaldehyde glue (commonly known as trialdehyde glue). In order to fundamentally solve indoor air pollution, it is necessary to develop a gre...
