Abstract
The invention discloses a preparation method of a cardanol-modified adhesive. The preparation method comprises that cardanol and paraformaldehyde undergo a reaction at a temperature of 55-60 DEG C at pH of 1.6-2.3 for 30-40min, the reaction product is heated to a temperature of 96-98 DEG C and then undergoes a reaction until a relative density index is satisfied, wherein when the relative density index is satisfied, the condensation polymerization reaction develops to a reaction endpoint, then resorcinol is added into the reaction product, the mixture undergoes a reaction for 30-40min, water and residual raw materials are removed, when the temperature is reduced to 50-55 DEG C, urea is added into the reaction product, the mixture undergoes a reaction for 30-40min to produce a finished product and the finished product is discharged. The preparation method has simple processes, is easy to promote, realizes good hydrophobicity of the cardanol-modified adhesive and reduces waste water discharge.
Description
Technical field
The invention belongs to phenolic resin adhesive technical field, particularly to a kind of preparation side of modified by cardanol adhesive
Method.
Background technology
Modified phenolic adhesive, with respect to traditional adhesive, has fire retardant, low toxicity and excellent heat resistance and thermal insulation.But
Modified phenolic adhesive also has some defects, such as high cost, be also easy to produce aging cracking, viscosity is low, penetration is strong, easy seep through, alkali resistance
Difference, poor to the bonding property of foreign material, the shortcomings of toxicity is big, and in traditional modified phenolic adhesive production process, using benzene
Phenol is reacted with 37% formalin, produces substantial amounts of industrial wastewater.On the other hand, with petrochemical materials price rise with
And the gradually exhaustion of natural mineral resource is so that people increasingly pay attention to natural reproducible resource in terms of preparing modified phenolic adhesive
Application.Anacardol is a kind of very rare natural biomass phenol, can replace the fine stone of multiple phenols in chemicals synthesis
Change raw material.The modified phenolic adhesive prepared for raw material using anacardol replacement phenol, can replace multiple phenols in chemicals synthesis
Fine petrochemical material.And due to containing unsaturated long-chain in anacardol structure, can improve phenolic resin pliability and
Hydrophobicity.
Content of the invention
It is an object of the invention to overcoming above-mentioned deficiency, following technical scheme is proposed：
The invention is intended to providing a kind of preparation method of modified by cardanol adhesive, for this invention provides following invent
Content：
A kind of preparation method of modified by cardanol adhesive, including：
Anacardol and paraformaldehyde are 1.6-2.3, react 30-40min, Ran Housheng under conditions of temperature 55-60 DEG C in pH
High-temperature is 96-98 DEG C and continues reaction, until reaching relative density index, represents that polycondensation reaction reaches terminal；Between being subsequently adding
Benzenediol, reacts 30-40min, goes moisture removal and residual raw materials, treat that temperature is reduced to 50-55 DEG C, adds urea, continues reaction
30-40min, discharging obtains finished product.
Further, anacardol and the mass ratio of paraformaldehyde are 6：1-6:2.
Further, the addition of resorcinol is the 1.1-1.5% of anacardol quality.
Further, the addition of urea is the 0.5-0.7% of anacardol quality.
According to technical solution of the present invention：
1st, with the anacardol of cheap environmental protection for Material synthesis epoxy curing agent；
2nd, in individual molecule structure, there are multiple unsaturated bonds, hydrophobicity performance can be made more preferable；
3rd, the phenol structure in anacardol and unsaturated long-chain can give the more preferable toughness of adhesive and water resistance；
4th, use paraformaldehyde to replace formalin, excessive waste water will not be produced.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content of present invention instruction, people in the art
Member can various modifications may be made or changes to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiment 1
Weigh 300g anacardol, 45g paraformaldehyde is added in four-hole bottle, above-mentioned solution drips HCl, regulation system
PH value be 1.6～2.3 between.Heating 30min about, make system be warmed up to 55～60 DEG C, stop heating, because reaction is put
Heat, system temperature can raise automatically.When in bottle, temperature is 96～98 DEG C, after continuing reaction 1h, sampling and testing resin is relatively close
Degree, reaches requirement to relative density, represents that polycondensation has reached terminal, adds resorcinol, continues reaction 30min, then takes out true
Blank pipe removes moisture and unreacted residual raw materials, cools to 50 DEG C about addition urea, continues reaction 30min discharging.
Claims (4)
1. a kind of preparation method of modified by cardanol adhesive is it is characterised in that anacardol and paraformaldehyde are 1.6- in pH
