Abstract

The invention relates to the technical field of chemical environment-friendly adhesives, and specifically relates to a waterborne thermosetting adhesive and a preparation method thereof. The adhesive is composed of a component A and a component B, wherein the component A is prepared from the following raw materials in parts by weight: 480-520 parts of soybean protein, 5-6 parts of fumed silica and 5-6 parts of aqueous bentonite; and the component B corresponding to every 480-520 parts of soybean protein is prepared from the following raw materials in parts by weight: 380-420 parts of thermosetting resin solution, 2.5-3.5 parts of urea, 2.5-3.5 parts of sodium dodecyl sulfate, 2.5-3.5 parts of sodium carbonate, 2.5-3.5 parts of sodium hydroxide, 1.5-2.5 parts of defoaming agent and 580-620 parts of water. The agents in the adhesive cooperate with each other to improve the cross-linking characteristic between the soybean protein and the resin base material, so that the adhesive has good stability, high adhesion strength and good mobility and water resistance.

Description

technical field [0001] The invention relates to the technical field of chemical environmental protection adhesives, in particular to a water-based thermosetting adhesive and a preparation method thereof. Background technique [0002] In today's world adhesive market, the consumption of adhesives in the wood processing industry is huge, among which wood-based panels consume the most adhesives, and a large part of wood-based panels now use phenolic resin adhesives and urea-formaldehyde resins. The adhesive is glued with melamine-formaldehyde resin, commonly known as "trialdehyde glue". However, the artificial panels made of these glues will release formaldehyde during use. As we all know, formaldehyde is listed by the World Health Organization as carcinogenic and teratogenic, which will endanger the environment and human health. At the same time, the raw materials of these glues are all non-renewable petroleum as raw materials. As oil storage becomes more and more tense, it...
