In the whole house custom-made panels, most of them are wood-based panels. As long as they are wood-based panels, they cannot be separated from glue. There are mainly three commonly used glues: urea-formaldehyde resin glue, phenolic resin glue, and melamine glue. Today Let’s analyze it for everyone.
1. Urea-formaldehyde resin adhesive is one of the most commonly used wood-based panel adhesives.
Urea-formaldehyde resin adhesive is mainly filled with formaldehyde and urea. A kind of adhesive which is processed by the material, the full name of urea-formaldehyde resin adhesive is urea-formaldehyde resin adhesive, abbreviated as urea-formaldehyde resin, urea-formaldehyde resin, the English abbreviation is UF (urea-formaldehyderesins).
urea-formaldehyde resin glue products are insoluble and infusible translucent solids with a lighter color. It has the characteristics of weak acid and weak alkali resistance, good insulation performance, poor initial viscosity, large shrinkage, large brittleness, water resistance, and poor weather resistance (referring to stability under temperature, humidity and pressure changes). It is easy to decompose when encountering strong acid and strong alkali. It is easy to decompose when exposed to damp and heat. Urea-formaldehyde resin adhesive is a kind of adhesive with good performance, low price, easy manufacture and wide application.
Formaldehyde-free adhesive is a polyurethane adhesive. Formaldehyde-free adhesives are mainly used in this type of adhesive, which is widely used in all aspects of life. Shoes and clothes use this type of adhesive. The wood-based panel and wood processing industry is a new type of green and environmentally friendly adhesive.
Second, phenolic resin adhesive is the earliest industrialized synthetic resin
phenolic resin adhesive is also the earliest synthetic adhesive.It is also the first structural adhesive prepared by modification and was first used in the aviation industry.
phenolic resin glue is prepared by polycondensation of benzene and aldehydes in the presence of a catalyst. The finished products of phenolic resin glue can be liquid, powder and film. It has high chemical stability and is not corroded by fungi and insects. It has high bonding strength, water resistance, oil resistance, abrasion resistance, corrosion resistance, aging resistance, and good heat resistance (long-term It can withstand a high temperature of 120 degrees under use), good insulation performance, and darker color.
melamine adhesive is a kind of environmentally friendly polymelamine adhesive, which is a kind of high-condensed polymelamine adhesive and melamine adhesive. Good stability, boiling water resistance, chemical resistance and electrical insulation; heat resistance and water resistance are better than phenolic resin and urea-formaldehyde resin glue, but after curing melamine adhesive layer is brittle, uncured glue The storage period is short. Liquid melamine glue is a milky white uniform viscous substance, and the cured melamine glue is colorless, transparent and rich in light color. melamine resin adhesives include melamine formaldehyde resin glue and melamine urea formaldehyde resin glue. The most commonly used is melamine formaldehyde resin glue, referred to as melamine resin glue.
Formaldehyde-free adhesive is a polyurethane adhesive. Formaldehyde-free adhesives are mainly used in this type of adhesive, which is widely used in all aspects of life. Shoes and clothes use this type of adhesive. The wood-based panel and wood processing industry is a new type of green and environmentally friendly adhesive.
