Problems solved by technology

However, since the raw materials for preparing urea-formaldehyde resin involve formaldehyde, formaldehyde will be released during the production and use of urea-formaldehyde resin, and the palm fiber mat products produced by using urea-formaldehyde resin will also release formaldehyde, and the release period is as long as 3 to 15 years. , causing serious harm to human health

Abstract

The invention discloses a formaldehyde-free adhesive and a method for producing a formaldehyde-free palm fiber mattress by using the formaldehyde-free adhesive. The formaldehyde-free adhesive is produced by using formaldehyde-free raw materials which are vegetable protein, a cross-linking agent, an auxiliary material and water. According to the method for producing the formaldehyde-free palm fiber mattress by using the formaldehyde-free adhesive, a palm fiber raw material is a natural coconut palm fiber yarn or a natural arenga engleri fiber yarn and is sequentially subjected to working procedures of felting, needling, glue spraying, drying, slicing, hot-pressing, side shearing and checking. The palm fiber mattress, the release amount of the free formaldehyde of which is far less than 0.050mg / m<2>.h (stated in QB1952.2-2004 spring soft mattress of upholstered furniture), can be produced according to the method. The free formaldehyde of the palm fiber mattress is only derived from the natural palm fiber, thereby the problem of formaldehyde release of the palm fiber mattress is fundamentally solved.

Description

technical field [0001] The invention relates to a building material product and an application method thereof, in particular to a formaldehyde-free adhesive and a method for using the same to produce a formaldehyde-free palm fiber mat. Background technique [0002] Palm fiber mat is a three-dimensional mesh material made of natural palm fiber filaments and adhesives. It is widely used in the production of mattresses, sofa cushions, car cushions and other products. According to the raw materials, the palm fiber mats currently on the market include coconut palm fiber and mountain palm fiber. of fiber filaments. Commonly used adhesives include natural latex, urea-formaldehyde resin, etc. [0003] Natural latex does not contain free formaldehyde. The free formaldehyde in the palm fiber mat produced by using natural latex as adhesive comes only from the palm fiber itself, and its content is extremely low. It can be regarded as a pure natural formaldehyde-free environmental prot...
