Description
Technical field
The invention belongs to wood processing fields, are related to the production of particieboard, in particular to a kind of life of particleboard with zero-formaldehyde emission
Production. art.
Background technique
Particieboard is one of the principal item for customizing household plate, is mainly added with timber or non-wood plant fibre raw material
Work applies adhesive and other additives at wood shavings (or particle), and assembly forms and through one kind artificial board made of hot pressing.Urea
Urea formaldehyde or modified urea-formaldehyde resin are the most commonly used adhesives of current artificial board, and wood-based plate is wide in finishing material indoors
General application can release formaldehyde in use process to some extent.There is harm to the health of human body in formaldehyde, with quality of the life
Raising and low-carbon environment-friendly theory be rooted in the hearts of the people, consumer wishes to obtain more healthy, more environmentally-friendly high-quality plate.Plane
Card is one of most popular plate of having furniture made to order at present, and dosage rapidly increases every year.
Artificial board controls Form aldehyde release, reaches E0Or zero-emission is the target that industry of artificial boards is pursued.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is disclose a kind of life of particleboard with zero-formaldehyde emission
Production method.
Technical solution:
A kind of production technology of particleboard with zero-formaldehyde emission, comprises the following steps, timber/broken veneer/section feeds intake → chips → flaking →
Particle drying → screening → glue compounding and applying → mats formation → precompressed → hot pressing → cutting edge → cooling → quenched → sanding → inspection point etc. →
It is packed and stored, in which:
In the particle drying step, the wood shavings moisture content after drying is in 1.5-2.5%；
It in the glue compounding and applying step, is layered and is glued using watch core layer, surface layer adhesive is no aldehyde rubber made from soybean cake, and sandwich layer adhesive is water
Property polyamide and PMDI；
In the step of mating formation, wood shavings moisture content is in 11-14% after the sizing of surface layer, and wood shavings moisture content is in 7-9% after sandwich layer is glued；
In the slab heat-press step, hot pressing temperature is 180-235 DEG C, using five sections of humidity provinces, hot pressing pressure 0-4MPa.
In the more excellent disclosed example of the present invention, in the glue compounding and applying step, surface layer addition manner is by prepared no aldehyde soybean
Glue, waterproofing agent emulsified wax pass through surface layer glue system and surface layer wood shavings uniform stirring；Sandwich layer addition manner is will be aqueous poly-
Amide, PMDI, waterproofing agent melt paraffin pass through sandwich layer glue system and sandwich layer wood shavings uniform stirring.
In the more excellent disclosed example of the present invention, in the glue compounding and applying step, resin added of the surface layer without aldehyde soybean glue is over dry table
The 11-14% of layer wood shavings quality, 0.5% that waterproofing agent emulsified wax additive amount is over dry surface layer wood shavings quality；The aqueous polyamides of sandwich layer
Ten thousand China are purchased from outside the amine 5-8% relative to over dry sandwich layer wood shavings quality, PMDI() it is 3-5kg/m3, the addition of waterproofing agent melt paraffin
Measure 0.5% relative to over dry sandwich layer wood shavings quality.
In the more excellent disclosed example of the present invention, in the glue compounding and applying step, the component of no aldehyde soybean glue by mass percentage:
The soy meal of 25-40%, the dispersing agent of 3-10%, 0.5% antibacterial mildew inhibitor and excess water.
Wherein, the soy meal was 200-300 mesh, powdery；
The dispersing agent is purchased from Guangzhou Xu Xiang Chemical Co., Ltd., and model NN0-B, it is evenly dispersed that dispersing agent facilitates soy meal
In glue, it is not easy to be layered；
The antibacterial mildew inhibitor is purchased from the vast biochemical Co., Ltd in Nantong, and model Xin Ke -01C, antibacterial mildew inhibitor is in order to prevent
Rotten, the raising stable storing phase occurs for rubber made from soybean cake.
Further, the preparation steps of no aldehyde soybean glue are as follows:
A, water, stirring plus lye pH adjustment are added in a kettle to 10-12；
B, soy meal and dispersing agent are added while stirring；
C, it is all dispersed in water to soy meal, antibacterial mildew inhibitor is added, stir 20-40min；
D, go out sample.
Beneficial effect
Using particieboard made from the method disclosed in the present, without containing the poisonous and harmful substances such as free formaldehyde, the first of plate
Aldehyde burst size is almost 0mg/100g, while its mechanical property meets country and company standard, overcomes current particieboard and contains
The deficiency of burst size of methanal；It is poor to solve the disadvantages that form using the surface layer MDI wood shavings, release agent need to be used to increase cost.This hair
The bright formaldehyde pollution for efficiently solving the problems, such as China's indoor environment, for wood-based panel product get rid of burst size of methanal provide it is new
Solution route.
