Description
Technical field
The present invention relates to field of adhesive technology, and in particular to a kind of Wood adhensive of wood pulp cellulose preparation.
Background technique
Bonding agent is that one kind can be by the material of homogeneous or heterogeneous surface bonding connection together, conventional use of glue
The features such as materials of adhesive has stress distribution continuous, light-weight, good airproof performance, technological temperature is low.Bonding bonding especially suitable for
The connection of different materials, different thicknesses, ultra-thin specification and complex component；Therefore, process is manufactured in the industrial products of today
In, the use of all kinds of bonding agents is very extensive.
Traditional wood working process generallys use the technologies such as riveting, joggle and fixes to complete the assembling of all kinds of components, but
It is in the heavy industrialization processing of today, conveniently the application of chemical adhesive is more extensive, and chemistry is viscous
Connect the connection that can also be applied to timber and other materials.
Currently, the competition of door and window industry is fiercer, for the quality and the market competitiveness for improving product, need to carry out constantly
Improvement.The energy saving wooden doors and windows of top grade being widely used in external window of building engineering include：Pure Wood-door window, aluminium clad wood doors and windows,
The big kind of the wooden aluminium composite door and window three.And the wooden aluminium composite door and window is because its outside is heat insulated shape bar of aluminum alloy, inside is the wooden decoration bar section,
Therefore the weather conditions of southern rainy, high temperature, humidity are suitable for.The knot of present domestic market processing and fabricating wood aluminium composite door and window
Structure is unreasonable, and secondary operation is wanted in aluminium layering assembly, and is also not very in the aspect of performance such as Wind-Pressure Resistance, air-tightness and sound insulation, heat-insulated
Ideal has still remained substantial portion of energy loss.Timber window is due to beauty, the feeling to get close to nature, has extraordinary city
Field prospect, but since the use environment of window is special, present increasingly rugged environment, such as haze weather, lead to timber window institute in addition
The bad environments at place, if the quality of timber window is unqualified, it is easy to occur to crack between ligneous piece, connect defective tightness, influence using
Effect leads to customer complaint, and therefore, research and development can be applicable in boisterous timber window adhesive special with before huge market
Scape.
The performance of wooden door and window and the performance of bonding agent are closely related.Currently used Wood adhensive all has good
Adhesive property, adhesive effect firm stable, but used in the bonding agent of part a large amount of organic molten with volatility and toxicity
Agent, this bonding agent have a degree of harm to environment in use, also will affect the body of bonding operator
Health.In addition, the durability of part bonding agent is insufficient, service life is shorter, is easy natural cracking after long-term use.Part glue
The longer curing time of stick is also a problem, this will affect the working efficiency of bonding wood.
A kind of wood flooring binder disclosed in number of patent application 201410131861.3.The binder can be used for
The splicing of timber floor is installed, but the type adhesive is there are adhesion strength deficiency, weatherability and the poor problem of anti-aging property,
It is easily broken off or generates in use crack.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of Wood adhensives of wood pulp cellulose preparation, should
Type Wood adhensive has good bond effect, and the adhesive strength of material is high, good weatherability, and anti-aging property is prominent.
A kind of Wood adhensive of wood pulp cellulose preparation, according to mass fraction, including following component in Wood adhensive：Third

The addition of preservative can make the holding time of the type bonding agent longer, avoid bonding agent oxygen during preservation
Change degradation and destruction of the rotten or performance by microorganism.
Preferably, starch selects the starch after oxidation modification.
After carrying out oxidation modification processing to starch using carboxyl or carbonyl, the interface of the starch and bonding agent material of main part is imitated
Fruit gets a promotion, and material compatibility is more preferable, and addition of the starch in bonding agent can be improved the gelling ability of bonding agent, shortens
Curing time, and make the film-formation result of bonding agent more preferable.
Preferably, emulsifier is iso-octyl polyoxyethylene ether or phenethyl phenol polyethenoxy ether.
The effect of emulsifier is the dispersion effect that material is promoted in bonding agent preparation, when it is dispersed in the surface of dispersate
When, dispersed phase can be made with charge, thus the droplet of dispersed phase can be prevented to condense mutually, keep the emulsion to be formed more steady
It is fixed.
10, the Wood adhensive of a kind of wood pulp cellulose preparation according to claim 9, it is characterised in that：The wood
The preparation method of material bonding agent includes the following steps：
According to mass fraction, polyvinyl alcohol and dibutyl maleate are added in reaction kettle, in reaction kettle be added go from
Sub- water increases the temperature in reaction kettle to 80-90 DEG C, and stirring to mixture is uniformly dispersed, and acrylic acid is added and adjusts mixture
Then emulsifier is added in pH value into reaction kettle, insulation reaction 40-60min after stirring, then by methyl acrylate, ureaformaldehyde tree
Rouge and vinyl acetate are added in reaction kettle, are increased the temperature in reaction kettle to 90-95 DEG C, are continued stirring and insulation reaction 15-
The temperature of product is reduced to room temperature after reaction by 20min, by sodium ethylene diamine tetracetate, nanometer calcium carbonate, starch, wood pulp
Fiber, defoaming agent and preservative are added in reaction kettle, are stirred 20-25min, obtain required Wood adhensive.
The present invention has following beneficial effect：
It has been used in the type bonding agent and has been added to the materials such as wood pulp cellulose, the association of other ingredients in the additive and adhesive component
Together, the adhesive strength of bonding agent can be made more preferable, improves the stability of bonding, the material of the type bonding agent is uniform, film forming
Effect is good, and the material solidification time is shorter, can have better compatibility with wood materials, promote the stability of bonding wood,
