Abstract
The invention discloses formaldehyde-free plywood and a preparation method thereof. The formaldehyde-free plywood is prepared from the following formula components in parts by mass: 20 to 30 parts of waste plastic, 10 to 20 parts of filling, 6 to 8 parts of a compatilizer, 6 to 10 parts of oxidized PE (Polyethylene) wax, 6 to 8 parts of polyvinyl alcohol, 1 to 3 parts of a curing agent, 10 to 12 parts of talcum powder, 10 to 15 parts of gypsum powder, 7 to 9 parts of aliphatic hydrocarbon wax, 4 to 6 parts of oxidized polyethylene, 6 to 8 parts of polypropylene and 1 to 3 parts of a lubricant. The invention provides the method for preparing the toxin-free and environment-friendly formaldehyde-free plywood by utilizing the waste plastic, so that the problem that the environment and human bodies are poisoned through releasing free formaldehyde of common plywood is solved; meanwhile, the invention provides a recycling and reutilization way of the waste plastic.
Description
Technical field
The present invention relates to glued board technical field, in particular to a kind of formaldehyde-free plywood and preparation method thereof.
Background technology
The adhesive that glued board and decoration plywood product in the market is used is mostly the glue containing formaldehyde components
Stick, product discharges a large amount of free formaldehydes during production and use and causes room air pollution, to producers and consumers
Healthy generation great threat.
The Chinese patent " high-density polyethylene glued board producing method " of Application No. 200710100722.4 discloses one
Kind ureaformaldehyde, the adhesive such as phenolic aldehyde are replaced with high density polyethylene (HDPE), assembly again after rolling pin hole respectively on veneer, then Jing add
Heat, pressurization prepare the production method of glued board.High density polyethylene (HDPE) (HDPE) is nontoxic, tasteless, and with good resistance to acids and bases,
But its loss of properties on aging, ESCR is poor, easy stress cracking, easily aging, yielding, particularly thermal oxidation meeting
Make its hydraulic performance decline.HDPE production glued boards are used alone, water resistance does not reach I class weatherability sheet material, and by rolling pin
Hole processes veneer, easily causes veneer stress concentration and generates a large amount of rift grain crackings, and the tensile strength parallel to grain of sheet material is substantially reduced.
The content of the invention
The invention provides a kind of formaldehyde-free plywood and preparation method thereof, the invention provides being prepared using waste plastic
