Description
Technical field
The invention belongs to adhesive fields, and in particular to a kind of environment-friendly type based Wood Adhesives and its application method.
Background technology
Based Wood Adhesives are that the surface glue of timber and timber or other objects is connected into the material being integrated.Utilize splicing skill
Different size, lignocellulose raw material of different nature are glued, are recombinated and Compound Machining by art, are produced suitable for difference
Plank, square bar and pressing of requirement etc..These all be unable to do without adhesive and adhesive bonding technique.For this purpose, adhesive and glue
Status of the connection technology in wood processing field just seems even more important.Development with social economy and living standards of the people
It improves, the demand to wood materials is also constantly increasing, since the demand and yield of timber are increased sharply, to required adhesive
Demand growth is also very fast, and there are about 70% adhesives to be used for wood-processing industry in China.China's adhesive industry development is fast
Speed, yield sharp increase, but adhesive production in China's disperses very much, has extensive and high-caliber producer only various schools of thinkers,
Most enterprise's production technology levels are low, equipment it is outmoded it is simple and crude, science and technology strength is weak, product quality is not high, three waste discharge is not met
National requirements for environmental protection, some indexs of correlation lack corresponding examination requirements and standard, this series of problems make adhesive industry
There are the larger wasting of resources and problem of environmental pollutions.
Adhesive is still based on the adhesive made of synthetic resin from petroleum resources used in current wood industry, such as
Phenolic resin and Lauxite, such adhesive are not only had excellent performance, but also cheap, and application technology is ripe.But it is resistance to simultaneously
Aqueous poor, free formaldehyde content is high, these adhesives can all release a large amount of formaldehyde during production and use, especially
Its decorate indoors and Furniture panel in, because of formaldehyde not fully polycondensation, often with the presence of considerable part with free state, meeting
It is gradually dissipated to surrounding and causes environmental pollution, cause to pollute environment and endanger public health, for this reason, it is necessary to research and develop a kind of wood
Timber-used is nontoxic, environmental type adhesive.
Invention content
The technical problems to be solved by the invention：Poor for current based Wood Adhesives water resistance, free formaldehyde content is high,
Toxicity is big, pollution environment and the problem of endanger public health, and the present invention improves a kind of environment-friendly type based Wood Adhesives and its use
Method.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of environment-friendly type based Wood Adhesives, including infiltration component, gluing enhance component；
The infiltration component is in mass ratio 1:3~6:2, by additive, complex liquid and protective agent；
The preparation method of the gluing reinforcing agent, includes the following steps：
（1）Take sawdust, surfactant and water in mass ratio 4:1:2 ~ 3 are put into ball mill and carry out ball milling, collect ball milling object, will
Ball milling object and ethanol solution in mass ratio 1:3 are put into steam blasting device and carry out steam blasting, collect steam blasting object；
（2）Steam blasting object is subjected to vacuum distillation recycling ethyl alcohol, residue is collected, counts in parts by weight, take 80 ~ 90 parts of hydrogen-oxygens
Change sodium solution, 60 ~ 80 parts of water, 30 ~ 40 parts of residues, 18 ~ 22 parts of taurines, 14 ~ 17 parts of N-（3- dimethylamino-propyls）Methyl
Acrylamide, 11 ~ 13 parts of divinylbenzenes, 4 ~ 7 parts of nano-titanium dioxides, 1 ~ 4 part of ferrous pyrophosphate and 3 ~ 6 parts of calcium mucins；
（3）Sodium hydroxide solution, residue, nano-titanium dioxide are put into container, 16 ~ 18h, mistake are stirred at 60 ~ 65 DEG C
Filter is collected filter cake and Washing of Filter Cake to neutrality is put into reactor, added taurine, ferrous pyrophosphate, protected using nitrogen
Shield, is warming up to 60 ~ 90 DEG C, and preheating adds N-（3- dimethylamino-propyls）Methacrylamide is warming up to 105 ~ 110 DEG C, protects
Temperature；
（4）It after heat preservation, is cooled to room temperature, collects substance in reactor, freeze-drying object is collected in freeze-drying, will be cold
Freeze dried object, divinylbenzene, calcium mucin to mill, collection mills object to get gluing reinforcing agent.
Preferably, the mixed enzyme is in mass ratio 3:1 ~ 1.6, peroxidase, extension albumen are mixed.
Preferably, the mixed liquor is in mass ratio 1：6：2, copper sulphate, water and ethylene glycol are mixed, then is added dropwise
6mol/L ammonium hydroxide continues that ammonium hydroxide is added dropwise until precipitation is completely dissolved to get mixed liquor after having precipitation to generate.
Preferably, the protective agent is Amifostine and 0.1mol/L sodium chloride solutions in mass ratio 1：20 ~ 25 mix.
Preferably, the surfactant is sodium sulfate of polyethenoxy ether of fatty alcohol, fatty alcohol polyoxyethylene ether ammonium sulfate
In any one.
The present invention also provides the application method of environment-friendly type based Wood Adhesives, which includes the following steps：
A. plank is taken, infiltration component is pressed into 10 ~ 13mg/cm2, plank both sides are uniformly applied to, the plank after smearing is placed in 28 ~
4 ~ 6h is stood at 35 DEG C, is then placed 10 ~ 15min at 70 ~ 80 DEG C again, is obtained pretreatment plank；
B. by gluing reinforcing agent and water in mass ratio 4:Mixture is pressed 13 ~ 16g/cm by 11 ~ 12 mixing2, uniformly it is applied to pre- place
Plank both sides are managed, the pretreatment plank after smearing is stacked, it is 2 ~ 4 pieces to stack number, is placed in press, 108 ~
115 DEG C, 3 ~ 5min of hot pressing under 1.5 ~ 1.8MPa, you can.
Compared with other methods, advantageous effects are the present invention：
（1）The present invention first infiltrates wood surface by infiltrating the mixed liquor in component, passes through the second two in mixed liquor
Alcohol permeability brings other substances infiltrated in component into, recycles the copper ammon solution formed in mixed liquor to wood internal cell
In cell wall destroyed, expand hole therein, and copper is supported on cell wall, due to the expansion of the hole of cell wall
Greatly, so that the peroxidase in mixed enzyme is handled the substances such as the substance such as colloid of cell wall, further increase hole, and
So that cell wall is dredged exhibition using extension albumen, but in order to avoid cell membrane is destroyed, cell membrane is protected using Amifostine；
（2）For the present invention after being handled wood surface by infiltration component, reusing gluing enhances component at it
Reason, is handled sawdust first with steam blasting, and the substances such as cellulose therein, lignin is made to be ruptured or be degraded,
Under the initiation of ferrous pyrophosphate, pass through N-（3- dimethylamino-propyls）Methacrylamide carries out at sulfonation sawdust
Reason, and taurine is loaded, increase the timber that sulfonation wood pellet is destroyed with cell wall by using the effect of taurine
The combination of cell, and be combined using calcium mucin and wood cell film, wood cell is supplemented, puppet is formed it into
Complete wood cell, while copper of the sulfonation sawdust absorption carriage on cell wall, increase conjugation between the two, gluing are made to increase
The tie that strong component is combined as wood surface iuntercellular increases between timber in conjunction with dynamics, while the diethyl in hot pressing
Alkenyl benzene makes to be crosslinked between substance as crosslinking agent, further increases gluing intensity, while in the effect of nano-titanium dioxide
Lower carry out auto polymerization, further increases gluing intensity, while improving water resistance.
Infiltration component and gluing the enhancing component of the present invention has synergistic effect, keeps safety of the invention non-hazardous, and without first
Aldehyde discharges, while Optical instrument is good, and water resistance is high, to human body and environmentally friendly.
