Problems solved by technology

However, the use of urea-formaldehyde resin adhesives and other adhesives has obvious disadvantages: these adhesives contain substances harmful to the human body, such as formaldehyde, benzene, toluene, xylene, and various harmful volatile organic compounds.
However, this kind of wood-based panel and composite floor produced with polyethylene as an adhesive still has room for improvement in terms of bonding strength and the like.

Abstract

The present invention provides a plant fibre product containing nontoxic adhesive and a production method thereof. The plant fibre product contains polystyrene as the adhesive. The production method of the plant fibre product comprises that the polystyrene is used as the adhesive for producing the plant fibre product by heat pressing. During the process of producing the plant fibre product, compared with the existing adhesive, the polystyrene adhesive reduces the content of toxic substance in the adhesive and improves the bonding strength at the same time, and has good water resistance and long service life; in addition, the plant fibre product prepared by the polystyrene adhesive does not contain moisture, so that the plant fibre product does not bubble easily, and moisture is not required to by vaporized during the course of processing, thereby shortening the production period; the plant fibre product has good flexibility; and an adhesive layer is colorless and does not influence the appearance of the product.

Description

technical field [0001] The invention relates to a plant fiber product containing a non-toxic adhesive and a production method thereof, in particular to an artificial board or composite floor containing polystyrene as an adhesive and a production method thereof. Background technique [0002] Adhesives need to be used in large quantities in the manufacturing process of plant fiber products (including wood products). For example, use wood or other wood-based panels to produce composite floors, or blockboard (large core board), particleboard, fiberboard, and other wood-based panels to bond veneer, printed decorative paper, melamine decorative panels and other materials to produce decorative panels. The most popular are adhesives such as urea-formaldehyde resin glue. However, there are obvious disadvantages in using adhesives such as urea-formaldehyde resins: these adhesives contain substances harmful to the human body, such as formaldehyde, benzene, toluene, xylene, and various...
