Problems solved by technology

[0003] Compared with foreign countries, there is a big gap in the application of additives in my country's papermaking industry. The overall situation is that the quantity is small, the variety is not large, and specialized production has not yet formed, which cannot meet the requirements of technological progress and product upgrading in the papermaking industry. Therefore, papermaking assistants In the future, it is necessary to vigorously develop environmental protection and green papermaking additives that can improve the environment, and develop papermaking additives that integrate multiple functions.

Embodiment Construction

[0027] Put 100 parts of diatomite raw soil (water content 50%) produced in Ma'anshan Village, Changbai County, 5 parts of wollastonite powder, 5 parts of heavy calcium, and 0.55 parts of cationic polyacrylamide into a kneader, and use a speed of less than 1000r / min Stir at a rotating speed of less than 1 hour to fully mix the materials; put the mixed materials into the dryer, and dry them at a temperature of 50°C~80°C for 2 hours to dry the materials, and put the dried materials into the pulverizer In the process, pulverize at a speed of 10000r / min or less for 5s, then add diatomite composite flocculant (patent application number: 201410769722.3) in the above ratio after pulverization, put it into a kneader and stir at a speed of 1000r / min or less for 1 hour or less, Mix the materials evenly, weigh them, and pack them to get the finished product.

[0028] The preparation method of the above-mentioned diatomite composite flocculant (patent application number: 201410769722.3) is...

Abstract

The invention relates to a functional filler additive used in the field of papermaking. The filler additive is made of the following raw materials in proportion by weight: 100 parts of raw diatomite, 5 parts of wollastonite powder, 5 parts of heavy calcium, 0.55 parts of cationic polyacrylamide, 33.2 parts of diatomite composite flocculant (patent application number: 201410769722.3), the present invention has eight major functions, namely: increase the pulp saving rate, prolong the service life of felt and mesh cloth, ease the burden of sewage treatment, and increase production , Improve paper physical indicators (ring pressure strength, strength tensile force, surface finish, color), save energy, save drying steam, help retention and drainage, and cost-effective.

Description

technical field [0001] The invention relates to a functional filler additive used in the field of papermaking and a preparation method thereof. technical background [0002] my country's paper industry continues to develop towards high-speed, continuous, and large-scale directions, and labor productivity continues to increase. Due to the lack of coniferous wood resources, the use of hardwood and grass raw materials continues to increase, and the recycling rate of waste paper is also increasing. High, therefore, the content of fine components in the slurry increases. Due to the worldwide shortage of water resources and the requirement to prevent pollution, papermaking must be closed and circulated water. In this case, from the perspective of saving energy, reducing pulp consumption and reducing the treatment load of papermaking drainage, it is necessary to keep the fine components and fillers in the pulp as much as possible, and at the same time strengthen the dehydration of ...
