Abstract
The invention discloses zero-formaldehyde plywood and a preparation method thereof. The plywood is prepared from formula components in parts by mass as follows: 15-25 parts of fibers, 4-6 parts of oxidized polyethylene, 1-2 parts of a surface treatment agent, 10-30 parts of modified unsaturated polyester resin, 10-20 parts of fine wood meal, 7-9 parts of aliphatic hydrocarbon wax, 6-8 parts of a white emulsion, 6-8 parts of polyvinyl alcohol, 1-3 parts of isocyanate, 13-15 parts of talc, 6-8 parts of modified polyvinyl acetate and 1-2 parts of a lubricant. The produced plywood contains no formaldehyde and is good in water resistance, high in mechanical property and good in paint adhesion, industrialization can be realized without transformation on an existing dry-method plywood production line, the problem of formaldehyde pollution in the living space can be effectively solved, and a new solution is provided for artificial board products for getting rid of the formaldehyde release problem.
Description
Technical field
The present invention relates to plywood technical field, in particular to a kind of zero-formaldehyde plywood and preparation method thereof.
Background technology
As living standard is improved, requirement more and more higher of the people to IAQ (indoor air quality).House decoration sheet material and furniture
It is three big plates, i.e. fibre board, particieboard and plywood that sheet material source is most of.They by timber (fiber, wood shavings or veneer) with
Urea-formaldehyde glue mixing compacting is formed, and formaldehyde can be slowly released in use, causes room air pollution, affects resident's body
Health, being chronically in the high environment of concentration of formaldehyde even can cause cancer.Over more than 100 years, the first of ureaformaldehyde product is attempted to
Aldehyde discharges, and produces little effect.Because its with low cost, water-fast corrosion resistant, intensity preferably, process is simple, social required quantity constantly increases on the contrary
Plus, the year output and demand of China are above million tons.National environmental protection portion is by three big plates and three big glue (ureas within 2015
Aldehyde glue, phenol glue and melamino-formaldehyde glue) list high pollution, high environmental risk register in, seriously constrain sending out for wood-based plate
Exhibition.Form aldehyde release impact how is eliminated, is the problem that timber industry needs constantly to probe into while ensureing product quality.It is big at present
Part research is concentrated with isocyanates as adhesive, realizes zero formaldehyde Wood-based Panel Production.
The content of the invention
The invention provides a kind of zero-formaldehyde plywood and preparation method thereof, the plywood that the present invention is produced is without first
Aldehyde, the water resistance of sheet material is good, and high mechanical properties, paint adhesion is good, need not change on existing dry method plywood production line
Make and be capable of achieving industrialization, the formaldehyde pollution problem in living space can be efficiently solved, be that wood-based panel product is broken away from formaldehyde and released
Problem is put there is provided new solution route.
For achieving the above object, the present invention provides following technical scheme：
