Abstract
The invention provides a method for preparing modified phenolic resin by adopting cardanol. The method adopts phenol, methanal, the cardanol, auxiliary agent and hydrochloric acid to have reaction; the pH value of a reaction system is controlled to be within the range of 1.5-2.0, the temperature is slowly raised to 80-90DEG C, and then heating is stopped; the heat of the reaction is released untilthe temperature of the reaction system is 100 DEG C, and the reactant begins to boil; and after heat preservation reaction is stabilized for 2-3h, decompression dehydration can be carried out, so that the phenolic resin can be obtained. The performance of the modified phenolic resin can be measured under the experiment condition, the softening point is 82-90 DEG C, the flowing degree is 2.9-5.0cm, the polymerization speed is 60-90S, the viscosity is 12-15mpa*s, and the temperature is 25DEG C. The method can greatly reduce the manufacturing cost of the phenolic resin, so that the phenolic resin has good market prospect. The phenolic resin is environment-friendly and has no volatile component, thus being successfully applied to the coating industry by consumers. Furthermore, the method improves the inoxidizability and the heat resistance of the phenolic resin.
Description
Technical field:
The present invention relates to chemical field, relate in particular to a kind of preparation method of macromolecular compound, is a kind of method that adopts cardanol to prepare modified phenolic resins specifically.
Background technology:
The existing many reports of the application of cardanol in resol, but the amount that substitutes phenol is not high, generally about 10%, Nguyen etc. think that cardanol substitutes amount and is not more than at 15% o'clock, and the synthetic resin can improve the chemical resistant properties of resin and the tensile strength and the flexural strength of resin significantly.
Modified by cardanol is become reactive thinner, substitute like product on the market.Make cardanol become the surfactivity dilute catalyst by modification.It is softening that this cardanol tensio-active agent can allow resol take place, and find that from chemist's Baeyer in 1872 resol is to today, resol owing to unique properties, be widely used and obtained to develop rapidly, current production rate is arranged the 6th in thermoplastics, arrange the 1st in thermosetting resin.Because closely piling up of the rigidity aromatic ring that methylene radical connects in the molecular structure makes the resin body become fragile, the easy oxidation of phenolic hydroxyl group on the resin and methylene radical, thermotolerance and scale resistance are bad, and therefore pure resol can not satisfy the market requirement that enlarges day by day.
In recent years the biomass resource cashew shell liquid (cashew nut shell liquid, CNSL) application at chemical field comes into one's own day by day, it is cardanol that CNSL handles the back main component through decarboxylation.Long alkyl chain between cardanol on the position has toughness, can overcome the fragility of pure phenolic resin, has enlarged its Application Areas.
Summary of the invention:
The object of the present invention is to provide a kind of method that adopts cardanol to prepare modified phenolic resins, it is crisp that the preparation method of described this modified phenolic resins will solve resol resin body of the prior art, the easy oxidation of phenolic hydroxyl group on the resin and methylene radical, the technical problem that thermotolerance and scale resistance are bad.
The invention provides a kind of method that adopts cardanol to prepare modified phenolic resins, described this method adopts phenol, formaldehyde, cardanol, auxiliary agent and hydrochloric acid to react, and the weight part of each material is as follows:
Phenol 100-120 part
Formaldehyde 80-90 part
Cardanol 40-45 part
Auxiliary agent 7-9 part
Hydrochloric acid 1.6-1.9
The pH value of reaction system slowly is warmed up to 80-90 ℃ between 1.5-2.0, stop the heating, exothermic heat of reaction comes to life for 100 degrees centigrade to system temperature, stablize insulation reaction 2～3h after, decompression dehydration promptly obtains resol.
Further, described phenol is phenol.
Under above-mentioned experiment condition modified resin is carried out performance measurement, softening temperature is 82-90 degree centigrade, and the trickling degree is 2.9-5.0cm, and polymerization velocity is 60-90S, and viscosity is 12-15mpa*s, 25 degrees centigrade.
The present invention and prior art compare, and its effect is actively with tangible.The present invention can make phenolic resin-made cause this to reduce greatly, is a kind of product of good market prospects; The client has been successfully applied to coating industry, and environmental protection does not have volatile component.The oxidation-resistance and the thermotolerance of resol have been improved.
Embodiment:
Based on phenol 100 weight parts, the hydrochloric acid of the formaldehyde of the cardanol of 45 weight parts, 85 weight parts, 1.8 weight parts and 7 weight part auxiliary agents are put into the four-hole round-bottomed flask, adjust pH to 1.5～2.0, slowly be warmed up to 80-90 ℃, stop the heating, exothermic heat of reaction comes to life for 100 degrees centigrade to system temperature, stablize insulation reaction 2～3h after, decompression dehydration obtains scarlet transparent solid---resol.
