Embodiment 1

[0033] Add 146 gram salicylic acid, 5.3 gram nickel chloride, 4.23 gram methanesulfonic acid, 106 gram styrene in the there-necked flask equipped with stirrer, reflux condenser, thermometer, be warming up to 125 ℃ while stirring, at 2 220 g of styrene was added dropwise within 1 hour, and the temperature was raised to 180° C. after the addition was completed, and the reaction was carried out for 3 hours. Then the temperature of the reaction system was reduced to 95° C., and 201.5 grams of prepared slurry (45 grams of zinc hydroxide, 5 grams of activated clay, 15 grams of isopropanol, 135 grams of water, 0.3 grams of polyvinyl alcohol, and 1.2 grams of sodium polyacrylate) were added, Reaction was carried out at the reaction temperature for 5 hours, and then rectification under reduced pressure was carried out to distill off unreacted substances. Finally, 525 grams of resinous activated clay modified aralkyl substituted salicylic acid resin zinc salts were obtained.

Embodiment 2

[0035] Carry out according to the method identical with embodiment 1, just replace the methanesulfonic acid in embodiment 1 with active clay. Finally, 523 grams of resinous activated clay modified aralkyl substituted salicylic acid resin zinc salts were obtained.

Embodiment 3

[0037] Carry out according to the method identical with embodiment 1, just replace the nickel chloride in embodiment 1 with lithium chloride. Finally, 526 grams of resinous activated clay modified aralkyl substituted salicylic acid resin zinc salts were obtained.

Abstract

The invention discloses a preparation method of modified aralkyl substituted salicylic acid resin polyvalent metal salt. Aralkyl substituted salicylic acid obtained by the reaction of salicylic acid or derivatives of the salicylic acid and styrene or derivatives of the styrene by a catalyst reacts with polyvalent metallic compound and activated clay mixture. The reaction temperature is 50-200 DEG C, and the time is 0.5-5 hours. Purification is carried out after the completion of the reaction, and the activated clay modified aralkyl substituted salicylic acid resin polyvalent metal salt is obtained. The preparation method provided by the invention has the advantages of simple process, no waste water and acid generated in the reaction process, high yield and no environmental pollution.

Description

technical field [0001] The invention belongs to the field of organic developer for pressure-sensitive and heat-sensitive recording paper, in particular to the field of zinc salicylate resin developer for pressure-sensitive carbonless copy paper. The invention relates to a preparation method of modified aralkyl substituted salicylic acid resin polyvalent metal salt. Background technique [0002] Carbonless copy paper is a kind of special paper that develops color by the contact reaction of colorless dye coated on paper and color developer. It is mainly composed of three layers: upper paper (CB), the back of this layer of paper is coated with non Microcapsules of colorless dyes in volatile solvents; middle paper (CF / CB), the front of this layer of paper is coated with a developer coating, and the back is coated with microcapsules; bottom paper (CF), this layer of paper CF coating with developer only on the front side. The principle of color development is that when pressure ...
