Abstract
A process for preparing paper-making disperser includes adding styrene and maleic acid anhydride in grammol ratio of 1 : 1 to organic solvent, addition of trigger, solution polymerization and water-bath heating.
Description
The invention belongs to multipolymer, specifically a kind of preparation technology of paper-making dispersant agent with two unsaturated aliphatic based compounds.
At present, the production of domestic noncarbon recording paper (having another name called pressure-sensitive carbon paper) is with the most of production domesticization of raw material, but wherein dispersion agent still needs import, and import price is higher, 1 ton about 50,000 yuans, and the user brought inconvenience in the use.
The preparation technology who the objective of the invention is to avoid above-mentioned weak point of the prior art and the paper-making dispersant agent that a kind of cost is low, price is low, dispersion effect is good is provided.
Purpose of the present invention can reach by following measure:
A kind of preparation technology of paper-making dispersant agent, the vinylbenzene and the MALEIC ANHYDRIDE that it is characterized in that getting mole ratio and be 1: 1 join in the organic solvent, add initiator again, adopt solution polymerization, and the heating in water bath mode can make product.
The present invention has following advantage compared to existing technology:
1. solvent of the present invention recovery capable of circulation is used again.
2. the product that provides, the user can directly use.
3. raw material all is homemade, for country has saved a large amount of foreign exchanges.
4. prospect is very extensive, can apply to industries such as papermaking, plastics, medicine, water treatment.
Embodiment:
In being furnished with the 500ml baking bottle of agitator, thermometer, reflux condensing tube; put into the MALEIC ANHYDRIDE of the vinylbenzene and 9.8 grams (0.1 mol) of 10.4 grams (0.1 mol); the dimethylbenzene or the toluene that add 250 grams again; in water-bath, heat; the benzoyl peroxide or the Diisopropyl azodicarboxylate that in the time of 30 °-50 ℃, add 0.2 gram; slowly heat up; in the time of 70 °-80 ℃, respond; control reaction temperature is no more than 100 ℃; sustained reaction 1-3 hour, be incubated after 1 hour the cooling miscellany; after the filtration, oven dry promptly gets product again.
In order to regulate molecular weight and controlled polymerization speed, can add molecular weight regulator or retarder.
Claims (4)
1, a kind of preparation technology of paper-making dispersant agent, the vinylbenzene and the MALEIC ANHYDRIDE that it is characterized in that getting mole ratio and be 1: 1 join in the organic solvent, add initiator again, adopt solution polymerization, and the heating in water bath mode can make product.
2, the preparation technology of a kind of paper-making dispersant agent according to claim 1 is characterized in that organic solvent adopts dimethylbenzene or toluene.
3, the preparation technology of a kind of paper-making dispersant agent according to claim 1 is characterized in that initiator adopts benzoyl peroxide or Diisopropyl azodicarboxylate.
4, the preparation technology of a kind of paper-making dispersant agent according to claim 1 is characterized in that temperature of reaction is at 70 °-100 ℃.
