Description
Technical field
The present invention relates to chemical field is and in particular to the formula of floor base material fibre board firming agent.
Background technology
Lauxite is the adhesive that current wood-based plate manufacturing is most widely used, rapid with wood-based panel industry
Development, also will greatly increase to the demand of Lauxite.In actual applications, in order to improve curing rate and guarantee after solidification
Glue-line there is enough cohesive strengths it is necessary to add firming agent or accelerator in Lauxite.The species of firming agent and use
Amount is the key factor of impact Lauxite product propertiess.The aqueous solution of strong acid weak base salt is faintly acid and its catalytic action tool
There is certain latency, be more satisfactory firming agent.At present China's wood processing enterprise the most commonly used be ammonium chloride, because
Its price is low, nonpoisonous and tasteless and water solublity is preferable, also can individually can apply with mixed with resin.But some nearest researchs are thought
Wood-based plate with ammonium chloride as firming agent is probably a potential environomental pollution source, because chloride timber-work is in burning,
The extremely strong dioxin of toxicity may be generated.Although there is no definite conclusion between the generation of dioxin and the use of ammonium chloride, mirror
In dioxin to the intensity of environmental hazard and persistent period, the process problem of the wood-based plate with ammonium chloride as firming agent is in many
Serious concerns are caused through industrialized country.The particieboard on the ground such as European Union member countries, Canada, New Zealand, medium density fibre board (MDF)
Manufacturer no longer or ammonium chloride will be stopped using, some production firms also using its product not containing ammonium chloride as the feature of environmental protection
Mark.Ammonium chloride has certain corrosivity to production equipment, and life-time service can cause to production equipment to damage.In this context,
We need a kind of urea formaldehyde resin curing agent of environmental protection, and separately in the curing process, if curing rate is too fast, glue-line is easily aging,
It is thus desirable to extending hardening time, and in actual production, curing rate also should not excessively slow it is therefore desirable to be controlled,
It is preferred within 200 to 350 seconds, optimal at 300 seconds about.
Content of the invention
It is an object of the invention to provide the formula of floor base material fibre board firming agent, urea formaldehyde resin curing agent not environmentally,
The problem that hardening time is inappropriate and solidification effect is not good.
For solving above-mentioned technical problem, the present invention employs the following technical solutions: the joining of floor base material fibre board firming agent
Side, comprises ammonium sulfate, carbamide, organic acid, water.The after-treatment that there is not ammonium chloride system under the effect of ammonium sulfate curing system is dirty
Dye problem, therefore can substitute ammonium chloride, and more environmentally-friendly.Lauxite in the curing process, has Form aldehyde release
Problem, adds carbamide, can PARA FORMALDEHYDE PRILLS(91,95) be caught, and reduces the release of formaldehyde, plays the effect of environmental protection.Simultaneously because ammonium sulfate is
Secondary ackd salt, therefore pass through dissociation and with formaldehyde react produced by hydrogen ion concentration higher so that curing reaction is too fast, and
After adding carbamide, this curing reaction can be played with the effect of buffering, the especially initial stage to curing reaction, it is to avoid solidification
Too fast, inner glue layer easily aging problem, and in the lifting of cured later speed, it is to avoid hardening time is long, and then meets solidification
The requirement of time.Add organic acid in system, be that curing reaction improves sour environment, the carrying out of triggering curing reaction.Component
In each composition cooperate, Lauxite solidification process is adjusted, meets wood-based plate solidifying requirements, and environmentally friendly.
Preferably, calculating by weight, comprise 15～25 parts of ammonium sulfate, 4～6 parts of carbamide, 70～80 parts of water, organic
Acid is less than 0.1 part.Lauxite is when firming agent ph is 4.5～6, optimal to the bonding strength of wood-based plate, therefore organic acid
Content should be less than 0.1 part.And through overtesting, the floor base material fibre board firming agent hardening time obtaining by above proportioning and solidification
Best results.
Preferably, also including triethanolamine, calculate by weight, described triethanolamine content is less than 0.05 part.
Triethanolamine has the characteristic of facile hydrolysiss, during Lauxite elevated cure, can produce hydroxyl, add the friendship of Lauxite
So that the structure of Lauxite is more tight in connection polycondensation reaction, improve bonding strength, meanwhile, triethanolamine is in alkalescence, whole
Play the effect of acid-base balance in individual system, therefore curing reaction can be played with the effect of buffering, extend hardening time, but three second
Alcohol amine content is unsuitable too high, controls optimal less than 0.05 part.
Preferably, also including phytic acid, also including phytic acid, calculating by weight, described phytic acid content is 0.01～
0.03 part.Lauxite corrosion resistance has much room for improvement, and adds phytic acid in firming agent, can improve the corrosion resistance at gluing and resist
Oxidisability, makes glued effect duration longer.Phytic acid is strong acid, and in firming agent, content is unsuitable excessive.
Compared with prior art, the present invention at least can produce a kind of following beneficial effect: the present invention is environment friendly and pollution-free；This
Bright promotion Lauxite solidification, can extend hardening time again, good to curing time control effect, meet and produce needs；The present invention
Lauxite is combined even closer, strengthen glue performance；The present invention can improve the resistance to water at wood-based plate gluing.
