Problems solved by technology

Wood-based panels are mechanically processed panels using natural wood and waste materials in processing. In the production process, most of them use urea-formaldehyde resin or modified urea-formaldehyde glue. This type of adhesive has bonding strength. High, not easy to open glue, but it will produce formaldehyde release under certain conditions, formaldehyde is determined by the World Health Organization as a carcinogenic and teratogenic substance, causing certain harm to human health

Abstract

The invention discloses a method for producing an environmentally-friendly lightweight composite board. The environmentally-friendly lightweight composite board is through the following steps: producing a composite fiber felt from natural fibers and polypropylene synthetic fibers, and performing a hot press molding technology through using a steel die. The environmentally-friendly lightweight composite board is produced from the natural fibers and the polypropylene synthetic fibers through using the thermoplastic technology, so the composite board is absolutely free from formaldehyde and otherharmful substances; a one-component water-soluble cold glue is a water-soluble polyurethane adhesive, and uses water as a medium, so the composite board is nontoxic, non-flammable, non-polluting andnon-hazardous, and can truly achieve zero formaldehyde environmental protection level; and the length, the width and the thickness of the lightweight composite board are correspondingly adjusted according to users' different needs, so the practicality is improved.

Description

technical field [0001] The invention relates to the technical field of energy-saving building materials and decorative materials processing, and more specifically relates to a manufacturing method of an environment-friendly lightweight composite board. Background technique [0002] At present, the traditional lightweight composite panels on the market are mostly made of wood-based panels, which are bonded with ordinary adhesives. Wood-based panels are mechanically processed panels using natural wood and waste materials in processing. In the production process, most of them use urea-formaldehyde resin or modified urea-formaldehyde glue. This type of adhesive has bonding strength. High quality, not easy to open glue, but it will release formaldehyde under certain conditions. Formaldehyde has been identified as a carcinogenic and teratogenic substance by the World Health Organization, causing certain harm to human health. [0003] With the improvement of living standards, peop...
