Abstract
The invention discloses a kind of modified phenolic resin adhesive and preparation method thereof, modified phenolic resin adhesive includes changing the rosin modified phenolic resin of property by acting on rosin, drying oil and aliphatic acid.Its preparation method comprises the following steps：The phenolic resin of 1 parts by weight and the rosin of 5.5~6.5 parts by weight are mixed, by 4 hours~4.5 hours, are heated to 230 DEG C, it is continuously agitated in heating, and the aliphatic acid of the drying oil and 1.0~1.2 parts by weight into 2.0~2.5 parts by weight is dripped, after being incubated 10 hours, it is cooled to normal temperature.The present invention compared with prior art, can solve the problems, such as existing phenolic resin adhesive indissoluble or insoluble in vegetable oil or alcohol.
Description
Technical field
The present invention relates to rosin deep process technology field, especially a kind of modified phenolic resin adhesive and its preparation side
Method.
Background technology
Existing phenolic resin adhesive is that phenols forms resin with aldehydes under catalyst action.Though urea formaldehyde adhesive
So have that glue-joint strength is high, water-fast, heat-resisting, wear-resisting and good chemical stability, during weather-proof, the heat-resisting timber-work of production
Synvaren is preferred adhesive, but wearability is relatively low, cost is higher, solidification temperature is high, hot pressing time because it is present
The problems such as long, it is difficult to widely used in every profession and trade, especially its it is less soluble or insoluble in vegetable oil or alcohol, it is necessary to heat up
It is bonded while hot after baking, even more directly hinders its use.
The content of the invention
Problem to be solved by this invention is to provide a kind of modified phenolic resin adhesive and preparation method thereof, existing to solve
There is phenolic resin adhesive indissoluble or the problem of insoluble in vegetable oil or alcohol.
In order to solve the above problems, the technical scheme is that：This modified phenolic resin adhesive includes passing through and pine
Fragrant, drying oil and aliphatic acid act on and change the rosin modified phenolic resin of property.
The preparation method of this modified phenolic resin adhesive comprises the following steps：By the phenolic resin of 1 parts by weight and 5.5~
6.5 parts by weight rosin mixing, by 4 hours~4.5 hours, be heated to 230 DEG C, heating when be continuously agitated, and drip into
The aliphatic acid of the drying oil of 2.0~2.5 parts by weight and 1.0~1.2 parts by weight, after being incubated 10 hours, it is cooled to normal temperature.
In the above-mentioned technical solutions, more specifically：The weight ratio of phenolic resin and rosin, drying oil and aliphatic acid is
1.0：6.5：2.0：1.0.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
This modified phenolic resin adhesive changes the phenolic aldehyde tree of property using the method acted on rosin, drying oil and aliphatic acid
The property of fat, modified phenolic resin is preferably dissolved in vegetable oil or alcohol, glued while hot after avoiding the need for heating baking
The problem of connecing, there is larger breakthrough using upper.Whole preparation process, it ensure that phenolic resin and rosin, dryness oil ＆ fat
Acid dissolves and permeated well, and reaction is more abundant.

Phenolic resin.
Its preparation method comprises the following steps：
The phenolic resin of 1 parts by weight and the rosin of 6.5 parts by weight are mixed, by 4.5 hours, are heated to 230 DEG C, in heating
It is continuously agitated, and drips the aliphatic acid of the drying oil and 1.0 parts by weight into 2.5 parts by weight, after being incubated 10 hours, is cooled to normal temperature
.
Embodiment three：
This modified phenolic resin adhesive includes changing the Abietyl modified of property by acting on rosin, drying oil and aliphatic acid
Phenolic resin.
Its preparation method comprises the following steps：
The phenolic resin of 1 parts by weight and the rosin of 6.0 parts by weight are mixed, by 4.5 hours, are heated to 230 DEG C, in heating
It is continuously agitated, and drips the aliphatic acid of the drying oil and 1.1 parts by weight into 2.3 parts by weight, after being incubated 10 hours, is cooled to normal temperature
.
