Abstract
The invention provides a cardanol-modified phenol resin and a preparation method of the cardanol-modified phenol resin. The cardanol-modified phenol resin comprises the following components by weight: 0.2-0.32 parts of cardanol, 0.7-0.8 parts of phenol, 0.58-0.8 parts of formaldehyde, 90-110 parts of sulfuric acid (2%), 0.5-0.6 parts of toluene, 0.5-0.6 parts of alcohol, 0.8-0.95 parts of epoxy resin 6101# and 0.15-0.25 parts of magnesium hydroxide. The prepared phenol resin provided by the invention has the characteristics of high flexibility, good processing properties and excellent acid and alkali resistance. The prepared phenol resin provided by the invention has the characteristics of high flexibility, good processing properties and excellent acid and alkali resistance.
Description
Technical field
The present invention relates to a kind of resol, particularly relate to a kind of modified by cardanol resol and preparation method thereof.
Background technology
Cashew nut tree has another name called the Jia if tree, extensively plants near the equator, and begin establishing in large scale in Hainan Island the eighties in 20th century.Long 2 ~ the 4cm of cashew nut tree fruit, shell is polynuclear plane, includes the reddish-brown oily liquids, and its weight accounts for 67% of nut, is referred to as cashew shell liquid, and its staple is a cardanol, the cashew nuts edible in the shell.As the sub product of cashew nut industry, it is that a kind of agriculture section reclaims resource, is the source of natural phenol.
Cashew shell liquid is because poisonous, and people's skin is had strong pungency and corrodibility, so once once went out of use at initial stage of development.In recent years, Along with people's is to the exploitation that deeply reaches application of the composition research of cashew shell liquid, and cashew shell liquid begins to be widely used on the industrial production as a kind of the most economic natural phenol.Compare with traditional resol, polymer-modified acidproof, the alkali resistance with higher snappiness, better machining property and excellence of cashew shell liquid is the outstanding monomer of producing resin compound.In addition, cashew shell liquid is polymer-modified to have a characteristic feature, has lower decline property and low temperature resistant abradability when promptly rubbing, and this makes its application aspect friction materials also rather extensive.
Summary of the invention
The object of the present invention is to provide a kind of modified by cardanol resol.
Another object of the present invention is to provide a kind of preparation method of modified by cardanol resol.
In order to realize the object of the invention, the technical scheme that the present invention adopted is following:
A kind of modified by cardanol resol is characterized in that, mainly forms by following components in part by weight,
Cardanol 0.2-0.32 part;
Phenol 0.7-0.8 part;
Formaldehyde 0.58-0.8 part;
Sulfuric acid (2%) 90-110 part;
Toluene 0.5-0.6 part;
Alcohol 0.5-0.6 part;
Epoxy resin 6101# 0.8-0.95 part;

The preparation method of modified by cardanol resol of the present invention is characterized in that, may further comprise the steps:
(1), cardanol, phenol and mass percent 63%～69% formaldehyde added the back that stirs in the reaction kettle add sulfuric acid (2%), be warming up to backflow, insulation 1h is cooled to 90 ℃ and vacuumizes 45min, is cooled to room temperature;
(2), in step (1) gained mixture, add remaining formaldehyde, being warming up to the insulation 2.5h that refluxes, it is transparent to be evacuated to material; Add toluene, alcohol and epoxy resin 6101# and stir 0.5h,
(3), in step (2) gained mixture, add the Marinco H furnishing type time to 1-3min/180 ± 2 ℃, filled stirring is cooled to blowing below 50 ℃.
The resol that the present invention prepares gained has higher snappiness, better machining property and excellent acidproof, alkali-proof characteristics.
