Problems solved by technology

However, although the solid wood adhesive prepared by the existing preparation method can solve the requirements on the strength of the solid wood splicing board, the adhesive is much faster than the solid wood aging, that is, the solid wood of the solid wood product has not aged yet and loses its practical performance. However, the adhesive has aged, and the solid wood products have fallen apart into a pile of waste wood, which greatly affects the life of the solid wood products and reduces their applicability, and the preparation methods are too complicated, and some have some harmful intermediate products, which affect the human body. healthy

Abstract

The invention discloses a preparation method for an anti-aging environmentally friendly solid wood adhesive. The method comprises the steps that water is added into a reaction still, a backflow deviceis started for stirring, and vinyl versatate is added into the reaction still, stirred for comprehensive dissolving and heated to 78-82 DEG C; an emulgator is added into the reaction still at a timeand stirred for 24 minutes, EVA emulsion, styrene-acrylic emulsion and carboxyl-butadiene emulsion are added, the stirring speed is increased to 120-170 r / min, and the mixture is stirred; a dispersingagent is added into the reaction still, after stirring, a cross-linking agent is added into the reaction still, and the temperature is preserved for reaction for 30-50 minutes; the temperature of thereaction still is decreased to 40-50 DEG C, a filler is added, and the mixture is stirred for 8-13 minutes to obtain the adhesive. The prepared adhesive has higher adhesive strength and is excellentin anti-aging performance, aqueous, environmentally friendly and pollution-free, the preparation method is simple, and no harmful intermediate products are produced.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a preparation method of an anti-aging environment-friendly solid wood adhesive. Background technique [0002] The traditional splicing of solid wood is connected and fixed by mortise and tenon. However, with the development of society, the profession of carpenter has also been replaced by machines and others, and this handicraft has gradually been lost. However, people's enthusiasm for solid wood products has not decreased, so the splicing of solid wood needs to be solved urgently, and solid wood adhesives have emerged as the times require. However, although the solid wood adhesive prepared by the existing preparation method can solve the requirements on the strength of the solid wood splicing board, the adhesive is much faster than the solid wood aging, that is, the solid wood of the solid wood product has not aged yet and loses its practical performance. However, the adhesiv...
