Abstract
The present invention relates to make the method for the oily molten shape rosin phenolic resin of light color, promptly magnesium oxide and the basic metal lithiumation thing with significant quantity is catalyzer, and to make the mole ratio of phenol and formaldehyde be 1: 1.2～2.0, thereby makes the product look number reach 8～9, saving phenol about 30%.In addition, it is good that the light colour modified rosin phenolic aldehyde resin made from the inventive method is still had a softening temperature height, oil soluble, can be widely used in the industries such as paint, printing ink, cable, printing, rubber, plastics, tackiness agent.
Description
The present invention relates to make the method for the oily molten shape modified rosin phenolic aldehyde resin of light color.
The method of known manufacturing modified rosin phenolic aldehyde resin (seeing " natural resin process technology " that Nanjing forest product industry institute compiles), be to be catalyzer with hexamethylenetetramine and zinc oxide, condensation reaction is taken place in phenol and formaldehyde in fused rosin, the mole ratio of phenol and formaldehyde is 1: 1.12, carry out addition reaction then, use glycerine esterification at last, phenol usage is 15.3% of a rosin consumption, and the products obtained therefrom look number is 11～12(iron cobalt method).
Product with the currently known methods manufacturing can not guarantee more shallow color, and because of phenol usage is bigger, makes manufacturing cost higher.
The purpose of this invention is to provide a kind of color of aufhellung modified rosin phenolic aldehyde resin, the manufacture method that reduction phenol consumes.
Reach this purpose, the method of making light colour modified rosin phenolic aldehyde resin is that magnesium oxide and the basic metal lithiumation thing with significant quantity is catalyzer, and the mole ratio of adjustment phenol and formaldehyde, make it is 1: 1.2～2.0, in fused rosin, carry out condensation, addition reaction, use glycerine esterification at last, make look and number be 8～9 yellow transparent rosin products.
Through test, if be catalyzer only, though but the color of resin aufhellung is opaque shape with magnesium oxide.And be catalyzer with magnesium oxide and basic metal lithiumation thing, when the two weight ratio is 1: 0.2～2.0, and significant quantity accounts for 0.01 of rosin consumption～1.0% o'clock, and color of resin is shallow and transparent, is 1: 0.5～1.5 to be the best with the two weight ratio especially.Basic metal lithiumation thing is selected Quilonum Retard or lithium hydroxide or both mixtures for use.
Other details of the present invention can be derived from following embodiment and Comparative Examples:
In the there-necked flask of being furnished with agitator, thermometer, condenser, after the prescription of the existing technology according to the form below in edge adds catalyzer, phenol, formaldehyde respectively, condensation reaction 3～4 hours, heat up dehydration to 220 ℃, add 58 parts of glycerine, 270 ℃ of following esterifications 4 hours, vacuumize 1 hour after, each test products is measured and is analyzed.
| Content instance | Gum resin (one-level) add-on (g) | Catalyst levels (g) | Phenol add-on (g) | Formaldehyde add-on (g) | The products measure value |
| One | 600 | Six methyne methylamines, 4.5 zinc oxide 1.2 | 91.8 | 88.1 | Look numbers 11, acid number 18,139 ℃ of softening temperatures, appearance transparent. |
| Two | 600 | Magnesium oxide 2.0 | 85 | 95 | Look numbers 9, acid number 17.5,138 ℃ of softening temperatures, outward appearance muddiness are opaque. |
| Three | 600 | Quilonum Retard 1.0 magnesium oxide 2.0 | 85 | 95 | Look numbers 8, acid number 16,140 ℃ of softening temperatures, outward appearance yellow transparent. |
| Four | 600 | Quilonum Retard 1.0 magnesium oxide 2.0 | 85 | 107 | Look numbers 8, acid number 17,152 ℃ of softening temperatures, outward appearance yellow transparent. |
| Five | 600 | Quilonum Retard 1.0 magnesium oxide 2.0 | 62 | 110 | Look numbers 8, acid number 18,138 ℃ of softening temperatures, outward appearance yellow transparent. |
Annotate: formaldehyde is 37% aqueous solution, and product colour is pressed iron cobalt method and measured
Advise making the method for light colour modified rosin phenolic aldehyde resin, guarantee that the product look number reaches 8～No. 9, softening temperature is more than 135 ℃, the outward appearance yellow transparent, both aufhellung product colour, also reduced phenol consumption (subtract and reach 20～30%), thereby reduced product cost, enlarged the product application scope.
