Abstract

The invention discloses a multifunctional special adhesive for wooden furniture and a preparation method of the multifunctional special adhesive. The adhesive is prepared from the following raw materials in parts by weight: 30-50 parts of lignin, 10-20 parts of oxidized starch, 15-30 parts of konjac glucomannan, 5-12 parts of pine oil, 2-6 parts of tung oil, 1-5 parts of boracic acid, 60-75 partsof water, 3-10 parts of an emulsifier, 1-3 parts of wormwood oil and 1-3 parts of eucalyptus oil. The adhesive is a pure natural plant extract, is prepared by a reasonable formula and a unique process, is high in wood adhesion ability, has functions of repelling mosquitos and refreshing air, and is particularly suitable for the wooden furniture.

Description

technical field [0001] The invention relates to the field of furniture materials, in particular to a special adhesive for multifunctional wooden furniture and a preparation method thereof. Background technique [0002] Adhesives are materials that use the stickiness of substances to connect and fix two separate materials together. Adhesive is one of the most important auxiliary materials whether in industrial production or daily life. With the improvement of people's living standards and more emphasis on physical health, the choice of furniture tends to be more functional, healthy and high-quality. Existing furniture is mainly made of various natural woods or artificial woods, usually using petroleum compounds such as urea-formaldehyde resins as adhesives for bonding, but most of these adhesives will release formaldehyde during use, causing serious damage to human health. harm. [0003] To this end, people have developed various types of environmentally friendly adhesives...
