The present invention relates to a paper sizing mixture, and more particularly to a paper sizing mixture that has a high sizing effect and is highly practical. In addition to rosin, carboxymethyl cellulose, polyvinyl alcohol, wax emulsion, alkyl ketene dimer, and the like are used as paper sizing agents, and more recently, substituted cyclic dicarboxylic acid anhydrides have also been used. Various emulsifiers are also known to be used in conjunction with the substituted cyclic dicarboxylic anhydride as a sizing agent. However, when conventional emulsifiers are used, it is necessary to perform high-speed stirring using a homogenizer to form an emulsion, which is very inconvenient. The object of the present invention is to provide a paper sizing agent mixture consisting of a specific sizing agent and a specific emulsifier, which eliminates the above-mentioned drawbacks. The present invention is based on the general formula (Here, Ar is an aralkyl group, m is an integer from 1 to 5,
n represents an integer of 10 to 80. ) is a paper sizing agent mixture consisting of polyoxyethylene aralkyl phenyl ether represented by the following formula and a substituted cyclic dicarboxylic acid anhydride. Polyoxyethylene aralkyl phenyl ether represented by the above general formula (1) is a new emulsifier for paper sizing agents, specifically polyoxyethylene α-methylbenzyl phenyl ether represented by the following formula. (where m and n are the same as above) or polyoxyethylene phenethyl phenyl ether represented by the following formula: (Here, m and n are the same as above). The emulsifier preferably has an HLB value of 14.5 to 18, more preferably 16.5 to 17.5. The HLB value can be adjusted by blending two or more substances with different properties in an appropriate ratio. Next, examples of the substituted cyclic dicarboxylic acid anhydride which is a sizing agent include those represented by the following formula. (Here, R represents dimethylene, trimethylene, and R' represents alkyl, alkenyl, aralkyl, or aralkenyl having 5 or more carbon atoms.) (Here, Rx and Ry represent C4 to C10 alkyl.) Regarding the mixing ratio of the above-mentioned sizing agent and emulsifier, it is appropriate to use 3 to 20 parts by weight of the emulsifier per 100 parts by weight of the sizing agent. By mixing this blend at a temperature of 50 to 100°C and cooling it, a mixture of the present invention in which each component is dispersed can be obtained. To explain how to use the paper sizing mixture of the present invention, water is gradually added to the mixture until the sizing agent concentration reaches 20%, and the mixture is stirred to form an emulsion. Then dilute to 0.5%.
At this time, there is no need to perform high-speed stirring using a homogenizer as in the prior art. Then for example 0.5%
The emulsion is added to a pulp slurry such as LBKP (Laubholz Bleached Kraft Pulp), and an appropriate amount of a fixing agent (boiled cationic starch, etc.) and a retention agent (cationic polyacrylamide resin, etc.) are added, and then paper is made. Then 100~
Dry at 130°C for 1 to 30 minutes and adjust the humidity as necessary to obtain a product. Measure the size degree of this product to find the size effect. When the paper sizing agent mixture of the present invention is used, a desired emulsion can be obtained with low-speed stirring, so it is highly practical and a high sizing effect can be obtained. Next, the present invention will be explained with reference to examples. Example 1 For 10 g of a substituted cyclic dicarboxylic acid anhydride synthesized by adding maleic anhydride to an isobutylene oligomer having 11 to 18 carbon atoms under reaction conditions of 210°C and 5 hours, = 2, n = 19, molecular weight 1137, HLB value 14.7 polyoxyethylene aralkyl phenyl ether (emulsifier A)
26.5% by weight, m=2, n=64, molecular weight 3117,
After adding 0.75 g of an emulsifier adjusted to an HLB value of 17.2 by blending 73.5% by weight of polyoxyethylene aralkyl phenyl ether (emulsifier B) with an HLB value of 18.1, 70 to 80
℃ and thoroughly mixed. Thereafter, the paper sizing agent mixture was cooled to room temperature or below, and water was gradually added while stirring the paper sizing agent mixture with a stirring blade to prepare a uniformly dispersed sizing agent emulsion with a concentration of 20%. It was further diluted with water and used as a 0.5% sizing emulsion for paper sizing. This paper sizing agent emulsion was used as a sizing agent for paper manufacturing, and the degree of sizing was evaluated by the Stekicht method in accordance with JIS P8122. The results are shown in Table-1. Note that the sizing process was performed by the following method. Beating degree 350ml (Canadian standard form of JIS P8121)
LBKP was made into a 0.5% pulp slurry, a paper sizing agent emulsion was added thereto, and the slurry was uniformly dispersed, and then paper was made into paper with a basis weight of 60 g/m 2 using a hand-sheeting machine (JIS P8209). This paper was dried in a rotary dryer at 110°C for 3 minutes, and then kept in a constant temperature and humidity atmosphere of 20°C and 65% RH for 24 hours. In addition, boiled cationic starch was used as a fixing agent and cationic polyacrylamide resin was used as a retention agent.
