Abstract

The invention discloses a preparation method of a lac-based environment-friendly artificial board adhesive. The lac-based environment-friendly artificial board adhesive is prepared from lac, an acid-base regulator, rosin, glycerol, ethanol and a modified accelerator. According to the preparation method, the adhesivity of the lac can be enhanced, and the lac-based environment-friendly artificial board adhesive does not contain benzene and formaldehyde, and can be used for manufacturing various artificial boards. The artificial boards manufactured through the adhesive can solve the problem that the harmful substances, such as formaldehyde, of the artificial board adhesive can bring pollution, the needed adhesion requirement of the artificial boards can be met, and the environmental friendliness property of the artificial boards can be improved.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a shellac-based environmental-friendly artificial board adhesive and a preparation method thereof. Background technique [0002] The wood-based panel industry is one of the important industries of my country's national economy. Its products are widely used, mainly used in construction and decoration materials, furniture, wooden floors, packaging materials, automobiles and sports culture. [0003] supplies etc. Since wood-based panel products are mainly used for furniture and interior decoration (wood floors and various decorative panels, etc.), most wood-based panels use formaldehyde-containing adhesives (the amount of urea-formaldehyde adhesives has reached 80% of the formaldehyde-containing adhesives), so , with the widespread use of wood-based panel products indoors, the harm of formaldehyde pollution to human health has become a social problem that needs to be solved urgently. ...
