Abstract
A surface sizing agent containing fragrance for papermaking comprises modified rosin resin, methyl methacrylate, a surfactant, a dispersing agent, an initiator, a perfume and a defoaming agent. The surface sizing agent prepared by the process has fragrance and safe fragrance, and the coated paper can cover the peculiar smell of the paper. Compared with the common sizing agent without fragrance, the sizing agent has stronger performance breaking strength, better stability and lower foamability after the sizing of paper.
Description
Technical Field
The invention relates to the technical field of organic silicon polymers, in particular to a surface sizing agent with fragrance for papermaking.
Background
The research work for synthesizing surfactants by using rosin began in the 20 s abroad. Rosin acid ester sulfonate, rosin amine polyoxyethylene ether and the like were synthesized in the 60 s. Since the 70 s, research work has been further intensive. The united states, germany, japan, and the former soviet union have conducted excellent and successful research in this regard. In the last three or forty years, a number of patents have been published abroad, which describe ionic, cationic, nonionic and amphoteric surfactants synthesized from rosin acid.
The existing surface sizing agent can greatly enhance the physical properties of paper, but can not change the peculiar smell brought by paper production, and is easy to cause discomfort of workers.

2) slowly adding the surfactant and the dispersing agent into the reaction kettle, opening a steam pipeline valve of a jacket of the reaction kettle, introducing steam, heating the system to 85 ℃, and fully stirring for about 1 hour;
3) adding an initiator, fully reacting to ensure that the solid content is 25-35%, cooling to below 45 ℃, adding a defoaming agent, and stirring;
4) adding a flavoring agent when gelatinization is about to be completed in the stirring process, and continuously stirring uniformly to finally obtain the surface sizing agent containing the fragrance for papermaking.
Preferably, the dispersant in step 2) is at least one of vinyl acetate acrylate copolymer salt, styrene-acrylate copolymer salt, casein, polyvinylpyrrolidone and polyvinyl alcohol.
Preferably, the flavoring agent in the step 4) is food-grade flavoring agent.
The surface sizing agent prepared by the process has fragrance, so that people feel comfortable, the fragrance is safe, and the coated paper can cover the peculiar smell of the paper. Compared with the common sizing agent without fragrance, the sizing agent has stronger performance breaking strength, better stability and lower foamability after the sizing of paper.
