Abstract
The invention discloses a kind of tripolycyanamide gluing agent addition agent and processing method thereof, bark powder is modified, making modified bark powder have faintly acid, to replace part flour, main formula technology is that each weight portion material is mixed in proportion and forms (usage percentage is): bark powder 30%-40%；Modifying agent 2%；Flour 58% 68%；The addition of described filler is the 20%～30% of total adhesive weight；The tripolycyanamide gluing agent addition agent of the present invention can effectively reduce the cost of glued board adhesive, effectively reducing delamination of plywood, bubble plate rate, weakly acidic condition also helps the curing reaction of tripolycyanamide gluing agent, thus strengthens bonding strength, strengthen water resistance, reduce burst size of methanal.
Description
Technical field
The present invention relates to a kind of tripolycyanamide gluing agent addition agent, a kind of tripolycyanamide gluing agent addition agent and
Processing method.
Background technology
In building template production process, in tripolycyanamide adhesive, the flour of gross weight 20-30% to be added is made
For filler；Traditional old technique impregnation method adding flour, only has bond stress in adhesive, and without Hydrogen bonding forces, face
Although the addition of powder improves solids content and adds tack, improve Pre-pressure property, add a large amount of flour in making sheet heat
Pressure hardening process can produce bigger contractility, produce substantial amounts of steam, it is easy to form bubble plate and come unglued plate, and tension
Intensity is low, moisture-sensitive, plastic deformation, sheet material do not have toughness.
Summary of the invention
In order to solve grain resource waste problem, improving bonding quality, the core of this project is to add modified bark powder, changes
After property, bark powder has faintly acid, and can replace part flour, main formula technology is that each weight portion material is mixed in proportion and forms
(usage percentage is): bark powder 30%-40%；Modifying agent 1.5%-2%；Flour 58%-68%.State the addition of filler
Amount is the 20%～30% of total adhesive weight；The present invention can effectively reduce the cost of glued board adhesive, effectively reduces glue
Delamination of plywood, bubble plate rate；Weakly acidic condition also helps the curing reaction of tripolycyanamide gluing agent, thus strengthens glued strong
Degree, strengthens water resistance, reduces burst size of methanal.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is:
Tripolycyanamide gluing agent addition agent, is mixed by following each raw materials by weight: bark powder 30%-
40%；Acid modification agent 1.5%-2%；Flour 58%-68%.
The processing method of tripolycyanamide gluing agent addition agent, including herein below:
(1) preparation of acid modification agent: take the formic acid of 85% and the oxalic acid 2:1 by volume of 99.5 purity mixes,
Weigh the configured good mixed solution ethanol dilution of 100g again and become 1L, shake up；
(2) bark powder screening: weigh bark powder by the percentage by weight of constitutive material, and sieved by acid-base value detection
Select non-strong basicity bark powder；
(3) weigh and the bark powder of the quality such as acid modification agent, then with high pressure watering can, acid modification agent is sprayed uniformly
It is spread across in the bark powder after screening, repeatedly to stir by stirring rod during sprinkling, stand in placing into 60 degrees Celsius of drying baker
24-36 hour；
(4) bark powder modified for above-mentioned steps (3) is put into 105 degrees Celsius of drying baker dried 2 hours, be dried
To moisture content less than 5%；
(5) bark powder is put into bark shredder to crush, be ground into threadiness, be finally putting into 120 mesh to 200
Purpose vibrosieve packs below row filter, screen cloth.
Described bark powder selected from non-strong basicity bark powder such as birch, Pinus koraiensis, Eucalyptus.
Described acid modification agent is to use the formic acid of 85% and the oxalic acid 2:1 of 99.5 purity to mix, and uses the most again
Ethanol dilution becomes melting concn to be 3%.
The addition of described additive is the 20%～30% of total adhesive weight.
The invention have the advantage that
The present invention can effectively reduce the cost of glued board adhesive, effectively reduces delamination of plywood, bubble plate rate；Faintly acid
Condition also help the curing reaction of tripolycyanamide gluing agent, thus strengthen bonding strength, strengthen water resistance, reduce formaldehyde
Burst size.
Detailed description of the invention
Embodiment 1, first, selects eucalyptus bark and through row modification, uses oxalic acid and formic acid as acid modification agent, modification
Dilution agent concentration is 3%, to eucalyptus bark chemical modification；Mainly the formic acid of 85% and the oxalic acid 2 to 1 of 99.5 purity are carried out
Mixing, then weigh the configured good mixed solution ethanol dilution of 100g and become 1L, shakes up, and weighs and the quality such as acid modification agent
Bark powder, is then sprayed onto acid modification agent in the bark powder after screening uniformly with high pressure watering can, wants anti-during sprinkling
Multiplexing stirring rod stirs, and stands 36 hours in placing into 60 degrees Celsius of drying baker；Again modified bark powder is put into 105 Celsius
Dried 2 hours in degree drying baker, is dried to moisture content less than 5%；Again bark is put into bark shredder to crush, powder
It is broken into threadiness, is finally putting into the vibrosieve with 120 mesh and packs below row filter, screen cloth.
When using as additive, main formula technology is that each weight portion material is mixed in proportion and forms (mass percent
It is): bark powder 40%；Acidic treatment modifying agent 2%；Flour 58%.
The addition of above-mentioned additive is the 25% of total adhesive weight.
The surface bonding intensity of the plastic-faced plywood building template of the high number of turnover of present embodiment and mechanical property
Index can be shown in Table 1.
Table 1 uses tripolycyanamide gluing agent addition agent plywood character
